Description:
'Color Coded Intravenous Administration Set"

Field of Invention

This invention relates generally to intravenous administration of medicaments and/or nutrients and, more particularly, to systems for intravenous administration of a plurality of edi- caments and/or nutrients contained in respective liquid containers.

Background of the Invention The intravenous administration of liquids or, more particularly, medicaments and/or nutrients (collectively referred to below as medicaments) is commonplace. A medicament is so administered using an administration set including means defining a flow path having an upstream or entry end adapted to be fluidly connected to a liquid container or reservoir, e.g. a bottle or bag, containing the medicament and a downstream or exit end adapted to be fluidly connected to a vasopuncture device which is inserted into the patient's blood vessel, e.g. artery. The flow path is defined over a major por- tion of its length by a flexible intravenous tube

formed of light-transmitting, e.g. clear, plastic material.

It is becoming more common to run a plu¬ rality of "I.V. lines" to a patient, i.e. to simul- taneously intravenously administer a plurality of medicaments from respective liquid containers through respective flow paths defined by a corres¬ ponding plurality of administration sets. This can be accomplished without difficulty when only two or even three lines are running.

It is not uncommon today for as many as six to nine different I.V. lines to simultaneously run through respective administration sets to a single patient. However, problems are often en- countered in such cases, especially where the exit ends of the flow paths of the administration sets are fluidly connected to vasopuncture devices lo¬ cated proximate to each other, such as in the blood vessels of the arms, neck and head. In particular, the flexible intravenous tubes of the administra¬ tion sets tend to become tangled and interwoven with each other as the patient moves or is moved by hospital personnel, due to the "memory" of the plastic material from which the tubes are made. The intravenous tubes generally tend to bow or spiral during use in an attempt to return to the curled form in which they were packaged. The tangled tubes must be simply and safely identified without the aid of additional equipment (e.g., separators) .

The tangling of intravenous tubes becomes a significant problem, for example, when it is nec¬ essary during a surgical procedure to inject anoth¬ er drug as quickly as possible through an inter-

mediate coupling provided in an existing I.V. line. Such situations occur for example, when a patient to whom a plurality of I.V. lines are running goes into shock and it is not possible to find another blood vessel into which to inject another drug. In such a case, it is the practice to inject the drug into the line or flexible flow path through which a benign medicament is already being administered, i.e. to "piggyback" an additional I.V. line with an existing line. However, it is not always an easy matter to distinguish one line from another in the short time available in emergency situations, such as during anaesthesia or during emergency surgical procedures. Catastrophic results may occur where a drug is inadvertently injected into an I.V. line through which a medicament is already flowing which is not compatible with the injected or "piggy¬ backed" drug. For example, if heparin or protamine is inadvertently injected into a line through which lidocane is already flowing, a flakey precipitate forms in the mixture which should not be injected into the patient's blood vessels.

It is seen from the foregoing that it is desirable to provide a system for the intravenous administration of a plurality of medicaments through a plurality of administration sets wherein the particular medicament flowing through each intravenous tube or line can be readily and reli¬ ably identified. Conventional attempts to administer a plurality of medicaments through a plurality of administration sets wherein the particular medica¬ ment flowing through each intravenous tube or line can be readily and reliably identified, include the

use of a plurality of administration sets wherein each intravenous tube or line for each administra¬ tion set includes indicia disposed at intervals along the length of the tube. Typically, the indicia is printed on the tubes at intervals of about six inches and is printed three times at each location along the tube, around its circumference. In other conventional administration sets the indicia is printed once at each location in a spi- railing pattern along the tube.

In the conventional administration sets, the I.V. tubing is constructed of clear plastic, so that the color of the fluid flowing therethrough may be easily identified. The type of indicia which is printed on the tubes includes letters, bands of color or other symbols.

However, the conventional intravenous administration sets have several drawbacks. First, the conventional systems require a three-step manu- facturing process. The clear plastic tubing is first extruded and then the indicia is applied to the tubing. The indicia is then sealed to the tubing. Secondly, as mentioned above, aside from where the indicia is printed along the tubing, the I.V. tubing is constructed of clear plastic. As such, if it is necessary to quickly administer a light sensitive medicament, such as ampicillin, the I.V. tubing must first be covered with a light shielding material, such as aluminum.foil. This seriously inhibits the quick administration of the medicament.

Thus, a need has arisen in the intraven¬ ous administration field for an administration set wherein the particular medicament flowing through

each intravenous tube can be readily and reliably identified, is easily manufactured and readily administers light sensitive medicaments.

The present invention provides a system for the intravenous administration of a plurality of different liquids to a patient. The system includes a plurality of flexible single-walled tubes which are fabricated of a polymeric material wherein the material used to form each tube has a different coloring agent from the material used to form the other tubes such that each of the tubes is of a different translucent color throughout its entire length. Since the tubes are translucent throughout their entire length, light sensitive medicaments can be administered by the system with¬ out providing further shielding of light. More¬ over, because the tubes are constructed of a poly¬ meric material having a coloring agent, the manu¬ facturing process is relatively simple, thereby reducing the overall cost of the administrative system. Consequently, use of the present invention results in a safer and more efficient medication delivery system without further increasing the cost of the administration set.

Summary of the invention

It is an object of the present invention to provide a new and improved apparatus for intra¬ venous administration of a plurality of medicaments contained in respective liquid containers. Another object of the present invention is to provide a new and improved apparatus for intravenous administration of a plurality of medi¬ caments contained in respective liquid containers

through a plurality of intravenous administration sets wherein the particular medicament flowing through an intravenous tube of an administration set can be quickly and reliably identified. Still another object of the present invention is to provide a new and improved appa¬ ratus for intravenous administration of a plurality of medicaments contained in respective liquid con¬ tainers through a plurality of intravenous ad in- istration sets and wherein another I.V. line for administering another drug can be readily and safely "piggybacked" with an intravenous tube of an existing administration set.

Briefly, in accordance with the present invention, these and other objects are obtained by providing a system for the intravenous administra¬ tion of a plurality of medicaments contained in respective liquid containers, comprising a plural¬ ity of liquid intravenous administration sets, each administration set including means defining a flow path from a point of entry adapted to be fluidly connected to a respective liquid container to a point of exit adapted to be fluidly connected to a vasopuncture device, the flow path being bounded over a portion of its length by a flexible intra¬ venous tube, and a plurality of indicia means, each respective indicia means designating a respective one of the liquid containers containing one of said medicaments and being associated with a respective one of the administration sets defining a flow path from that one of the liquid containers.

In accordance with a preferred embodiment of the invention, the plurality of indicia means comprise a plurality of respective colors, each

color designating a respective one of the liquid containers containing one of the medicaments and being associated with a respective one of the administration sets defining a flow path from that one of the liquid containers.

An intravenous tube of each administra¬ tion set is formed of a light-transmitting trans¬ lucent plastic material and in one embodiment has a respective color comprising a respective indicia means associated with the intravenous administra¬ tion set.

Each of the administration sets may include, in addition to the flexible intravenous tube, at least one injection coupling means for adding or "piggybacking" additional medicaments into the flow path between the points of entry and exit therefrom, entry means for fluidly connecting the point of entry of the flow path to a respective container, valve means disposed along the flow path for adjusting the rate of flow of liquid there¬ through, and/or exit means for fluidly connecting the point of exit of the flow path to a respective vasopuncture device. One or more of the injection coupling means, entry connecting means, valve means, and/or exit connecting means may have indi¬ cia means associated therewith.

Briefly stated, the present invention comprises a system for the intravenous administra¬ tion of at least two different liquids to a pat- ient. The system comprises a first flexible si gle-walled tube having a first end, a second end and an interior area for administering a first liquid to a patient. The first tube is fabricated of a polymeric material having a coloring agent

such that the first tube is of a first color throughout its entirety. The second end of the first tube receives insertion means for placing the tube in fluid communication with the patient. A first container is provided for storing the first liquid in an interior area thereof. The first container is fabricated of a polymeric material having a coloring agent such that the first con¬ tainer is of the first color through its entirety. The first end of the first tube is in fluid com¬ munication with the interior area of the first container. A second flexible single-walled tube has first end, a second end and an interior area for administering a second liquid to a patient. The second tube is fabricated of a polymeric material having a coloring agent such that the second tube is of a second color throughout its entirety. The second end of the second tube re¬ ceives insertion means for placing the second tube in fluid communication with the patient. A second container is provided for storing the second liquid in an interior area thereof. The second container is fabricated of a polymeric material having a col¬ oring agent such that the second container is of the second color throughout its entirety. The first end of the second tube is in fluid communi¬ cation with the interior area of the second con¬ tainer. As such, the first and second tubes and the first and second liquids within the first and second tubes can be readily identified by the color of the tubes and containers.

Brief Description of the Drawings The foregoing summary, as well as the following detailed description, is better under¬ stood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, embodiments which are presently pre¬ ferred are shown in the drawings. It is under¬ stood, however, that this invention is not limited to the precise arrangements and instrumentality shown. In the drawings:

Description of the Preferred Embodiment Certain terminology is used in the following description for convenience only and is not limiting. The words "right", "left", "lower" and "upper" designate directions in the drawings to which reference is made. The words "inwardly" and

"outwardly" refer to directions toward and away from, respectively, the geometric center of the administration system and designated parts thereof. The terminology includes the words above εpecific- ally mentioned, derivatives thereof and words of similar import.

Referring now to the drawings wherein like reference characters designate identical or corresponding parts throughout the several views, and more particularly to Fig. 1, a system in accordance with the invention, generally designated 10, for intravenous administration of four differ¬ ent medicaments A, B, C, D contained in respective fluid reservoirs or containers 12a, 12b, 12c, 12d to a patient 20 located on an operating table 22 is illustrated. The bottles 12a-12d are suspended from a hanger bar 26 by hooks 24. Hanger bar 26 is supported on a stand 28 mounted on a base 30.

System 10 comprises four intravenous ad- ministrations sets 32a, 32b, 32c, 32d, each includ¬ ing means defining a flow path from an upstream point of entry coupled to a respective reservoir of medicament A-D in a respective bottle or container 12a-12d to a downstream point of exit coupled to a respective vasopuncture device 34a, 34b, 34c, 34d. Each flow path is bounded over a major portion of its length by a flexible, single-walled tube 36a, 36b, 36c, 36d. Each tube 36a, 36b, 36c, 36d includes a first end 37a, 37b, 37c, 37d, a second end 39a, 39b, 39c, 39d and an interior area 41a, 41b, 41c, Id for administering a liquid or medi¬ cament to the patient 20. As seen in Fig. 1 the various flexible intravenous tubes 36a-36d have a tendency to bow or curve and accordingly, become

tangled or interwoven with each other, especially when the vasopuncture devices are located in prox¬ imity with each other, such as in the example il¬ lustrated in Fig. 1. It is understood by those skilled in the art that the present invention is not limited to any particular number of administration sets 32. That is, the administration system 10 can be com¬ prised of two administration sets, nine adminiε- tration setε or any number of administration sets without departing from the spirit or scope of the invention.

In order to quickly and reliably identify a particular medicament flowing through a particu- lar intravenous tube 36, each of the tubes is formed of a light-transmitting plastic material having a particular color, each color designating a particular one of the containers 12a-12d containing one of the medicaments A-D. In the present embodi- ment, it is preferred that each of the tubeε 36 be fabricated of a polymeric material, such as poly¬ ethylene, having a coloring agent such that each tube iε of a different color throughout itε entire¬ ty. In the preεent embodiment, it iε preferred that the coloring agent be a dieεtuff (pigment) . However, it iε understood by those εkilled in the art, that the present invention is not limited to any particular type of coloring agent.

Similarly, it is preferred that each of the containers 12 be fabricated of a material sel¬ ected from the group consisting of a polymeric or ceramic material, such aε polyethylene or glass, respectively, having a different coloring agent than the coloring agent of the other respective

containex-ε 12 such that each of the containers is of a different translucent color throughout its entirety, but is identical to the color of its associated tube 36. It is understood by those skilled in the art, that the tubes 36 can be formed of any poly¬ meric material and that the containers 12 can be formed of any polymeric or ceramic material. For instance, the containers 12 could be constructed of plexiglas without departing from the εpirit and εcope of the invention.

Conεiεtent with εtandard dictionary usage the term "light transmitting plastic" includes clear, transparent and translucent plastic. For example, Webεter'ε 9th Collegiate Dictionary states that "clear" implies "absence of cloudiness, hazi¬ ness or muddinesε", "tranεparent" implieε "being εo clear that objects can be seen distinctly" and "translucent" implies "the passage of light but not a clear view of what lies beyond." Similarly, The American Heritage Dictionary states that "trans¬ lucent" implies the transmiεsion of light "but causing sufficient diffusion to eliminate percep¬ tion of distinct images." Thus, an object that is translucent iε not transparent. The light trans¬ mitting plastic material may be of any color with¬ out departing from the spirit and scope of the invention so long as the light-transmitting plastic material iε of the same color in each ad inistra- tion set.

In the present embodiment, it is pre¬ ferred that the intravenous tubes 36a, 36b, 36c and 36d be formed by a εtandard injection molding or extrusion process. Preferably, the coloring agent

iε added directly to the material to be extruded or injected before the material iε injected or extrud¬ ed. However, it iε understood by those εkilled in the art that the intravenouε tubes 36a, 36b, 36c and 36d can be formed by other conventional manu¬ facturing methods without departing from the spirit and scope of the invention. For instance, the tubes 36 could be constructed of a clear plastic material and then dyed or painted to achieve the different colors thereof.

In the present embodiment, it is pre¬ ferred that the amount of coloring agent in the polymeric material of the tubeε 36 be sufficient to effectively diffuse light pasεing through the wall of the tubeε 36 and into the interior area thereof to maintain effective adminiεtration of a light εenεitive liquid or medicament. Similarly, the amount of coloring agent in the containers 12 is sufficient to effectively diffuse light pasεing into the interior area thereof to maintain effec¬ tive administration of light sensitive liquids or medicaments (e.g., nitropruεside) . Further, examples of such light sensitive liquid or medica¬ ments include inter alia, anaestheticε, antibi- otics, such as, erythromycin ethylsuccinate; erth- romycin stearate; ampicillin; ampicillin trihy- drate; penicillin P potasεium; and penicillin V potassium and vitamins, such as. A, B2, B6, C, etc. In the present embodiment, the blue color of intravenouε tube 36a designates medicament A contained in bottle 12a, the yellow color of tube 36b deεignateε medicament B contained in bottle 12b, the red color of tube 36c deεignateε medica¬ ment C contained in bottle 12c, and the green color

of tube 36d deεignateε medicament D contained in bottle 12d. The different colorε thus comprise a plurality of indicia means, each one of which des¬ ignates a particular one of the liquid containers 12 containing a particular one of the medicamentε. Each indicia meanε iε aεsociated with a respective one of the administration sets 32a-32d which de¬ fines a flow path from the particular liquid con¬ tainer 12 designated by that indicia means. It is understood by those skilled in the art that the present invention is not limited to each intravenous tube 36a-36d being of a single color throughout its entirety but that the intra¬ venous tubeε may possess an uncolored portion, or may possesε more than one indicia. Similarly, one of the plurality of intravenouε tubeε or admin¬ istration sets may entirely or partially be color¬ less.

Each administration εet 32 includes an entry adaptor 40a, 40b, 40c, 40d at the upstream end of the flexible intravenouε tube 36a-36d for fluidly connecting the intravenouε tube to a par¬ ticular bottle 12a-12d, a valve meanε or flow regulating clamp 44a, 44b, 44c, 44d disposed along the length of the intravenous tube 36a-36d for adjusting the rate of flow of liquid medicament therethrough, and upper and lower injection coup¬ lers 46a-46d; 8a-48d provided between the entry and exit adapterε compriεing portε through which additional medicaments can be administered through the intravenous tube.

The second end of each tube 36 receives inεertion means for placing each tube 36 in fluid communication with the patient. In the present

embodiment, it iε preferred that the inεertion meanε comprise an exit adapter 42a, 42b, 42c, 42d, as iε understood by thoεe εkilled in the art. Pre¬ ferably, the exit adapter 42a, 42b, 42c, 42d fluid- ly connectε the intravenous tube to a particular vasopuncture device 34a-34d. However, it iε under¬ stood by those skilled in the art, that insertion means can comprise any structure or method for placing the tube 36 in fluid communication with the patient.

In accordance with the invention, a re¬ spective one of the colors comprising the indicia means aεεociated with a particular adminiεtration εet may be applied to one or more of the entry adaptorε 40, the exit adaptorε 42, the valves 44 and the injection couplers 46, 48, asεociated with that adminiεtration εet, either in addition to or in lieu of applying that color to the intravenouε tube 36. Thuε, the entry adaptor 40a of adminis- tration set 32a may have the color blue associated with it (Fig. 2) , the exit adaptor 42b of the ad¬ ministration set 32b may have the color yellow asεociated with it (Fig. 5) , the injection coupler 46c of adminiεtration εet 32c may have the color red aεεociated with it (Fig. 3) and the valve means 44d of adminiεtration set 32d may have the color green associated with it (Fig. 4) .

Thus, each of the elements or hardware comprising the administration set may be provided, either alone or in combination with other elements of that administration set, with a particular one of the indicia means asεociated with the particular bottle 12 to which the flexible tube iε coupled. It is understood by those skilled in the art, that

the entry adaptors 40, the exit adaptors 42, the valves 44 and other asεociated hardware of the administration set may be of different contrasting color, without departing from the spirit and scope of the invention.

It iε particularly advantageouε to pro¬ vide the indicia meanε on the injection couplerε 46 and 48 εo that the particular medicament flowing through the flow path defined by a particular ad- miniεtration εet can be readily ascertained when it is desired to "piggyback" or inject another drug or medicament into an existing intravenouε tube 36 through the couplerε. Aε εhown in Fig. 3, the injection couplers preferably include an insertion portion 49c for receiving fluid from a different administration set. The inεertion portion 49c is preferably of the same color aε the tube of a dif¬ ferent adminiεtration εet to thereby facilitate piggybacking another liquid. Of course, the flow through portion 51c of the injection coupler 46c is preferably of the same color aε the tube 36c.

It iε of courεe possible to also asεoci- ate reεpective indicia meanε with the bottleε 12 containing the reεpective medicaments. However, this may not be neceεεary in the caεe where re¬ εpective indicia meanε are provided on the entry adaptorε 40 which are located adjacent to each of the reεpective bottleε. Indeed, referring to Fig. 2, each of the entry adaptorε 40 may include a hollow εpike 50 which extendε into the bottle when the administration set is coupled thereto. This εpike is generally visible within the bottle after connection and if provided with indicia means as

shown will provide ready identification of the particular medicament contained therein.

It will be understood that when color indicia are used, the colors may be applied to the respective administration sets in a manner other than as described above in connection with the il¬ lustrated embodiment. For example, color indicia may be applied to each administration set by apply¬ ing adhesive tape of an appropriate color to a por- tion or all of the intravenous tube of each admin¬ istration set. More typically, and aε indicated above, however, color will form an integral part of the extruded or injection molded tube. Moreover, it will be underεtood that indicia meanε other than colors may be utilized in accordance with the in¬ vention. For example, numbers, letterε, etc. may be utilized aε indicia means in accordance with the invention.

While it is understood that the preεent invention is not limited to any particular poly¬ meric material, ceramic material or coloring agent, the materials choεen should conform with Food and Drug Administration Standards to decrease the pos¬ sibility of harming the patient 20. The present invention is directed to a system for intravenous administration of a plural¬ ity of medicaments and/or nutrients contained in respective liquid containers. The εyεtem includes a plurality of liquid intravenous adminiεtration sets. Each administration set includes meanε for defining a flow path from a point of entry of the flow path adapted to be fluidly connected to a respective liquid container to a point of exit of the flow path adapted to be fluidly connected to a

vasopuncture device. The flow path iε bound over a portion of itε length by a flexible intravenouε tube. A plurality of indicia meanε iε provided to designate a respective one of the liquid containers containing one of the medicaments and/or nutrients and is associated with a respected one of the ad¬ ministration sets defining a flow path from the one of the liquid reservoirs.

From the foregoing description, it can be εeen that the present invention comprises a system for the intravenous administration of at least two different liquids to a patient. It iε appreciated by those skilled in the art that changes could be made to the embodiment deεcribed above without departing from the broad inventive concept thereof. It iε understood, therefore, that this invention iε not limited to the particular embodiment diεcloεed, but it iε intended to cover all modificationε which are within the εcope and spirit of the invention aε defined by the appended claimε.
