Description:
INVENTION TITLE Bacteriostatic Pocket Medical Scrub CROSS REFERENCE TO RELATED APPLICATIONS [Para 1] This application is a continuation of application Ser. No.16/940,282 filed on July 27, 2020 the entire contents of which is hereby expressly incorporated by reference herein.

TECHNICAL FIELD [Para 2] This invention relates to improvements in medical scrubs. More particularly, the present bacteriostatic pocket medical scrub includes a bacteriostatic pocket that reduces or eliminates bacteria and viruses on items placed within the pocket.

BACKGROUND ART [Para 3] In late 2019 and 2020 an outbreak of a virus spread across the globe to create a pandemic. One form of transmission of the virus is / was from surface contact and transfer of the bacteria. In hospitals and other settings some medical equipment such as stethoscopes and other non-disposable equipment could transfer bacterial from one person to another. The use of anti-bacteria sprays, cream or jellies can be applied before and / or after each use of the stethoscope can be used, but some anti-bacteria material can cause harm to the stethoscope or the skin of a patient. [Para 4] Ancient civilizations exploited the antimicrobial properties of copper long before the concept of microbes became understood in the nineteenth century. In addition to several copper medicinal preparations, it was also observed centuries ago that water contained in copper vessels or transported in copper conveyance systems was of better quality (i.e., no or little visible slime or biofouling formation) than water contained or transported in other materials. [Para 5] A number of patents and or publications have been made to address these issues. Exemplary examples of patents and or publication that try to address this /these problem(s) are identified and discussed below. [Para 6] U.S. Patent Number 6,286,147 issued on September 11, 2001 to James E. Ingold and is titled Stethoscope support. This patent discloses a stethoscope support assembled onto a garment to be worn by a medical practitioner. The garment is provided with a stethoscope bell holder pocket adjacent one shoulder thereof that is sized to slidingly hold a bell of a stethoscope. A first attachment component is connected to the garment adjacent a second shoulder thereof. A complementary attachment component is connected to the stethoscope in the area of its headpiece. While this patent provides support for a stethoscope in a garment, there is no mechanism to reduce bacteria. [Para 7] US Design patent D750,345 issued on March 1, 2016 to Billy Zackery Earley is titled Medical Scrub Uniform. This design patent discloses medical scrubs with at least an elongated pocket for storage of a stethoscope. [Para 8] U.S. Patent Number 10,182,788 issued on January 22, 2009 to Marcus De La Fuente and is titled Stethoscope Securing Device. This patent discloses a device comprises two reversibly connectable connector halves that can be attached at different points along the stethoscope, such that a stable closed loop can be formed when the two halves are in the connected position. The halves can be unconnected easily by the user when the stethoscope is desired to be used, but resists unintended or accidental disconnection. While this patent offers another method to hold a stethoscope it also does not reduce bacteria on the stethoscope. [Para 9] What is needed is a bacteriostatic pocket medical scrub where a stethoscope can be stored in the pocket when not being used and bacteria on the stethoscope is cleaned between uses. The bacteriostatic pocket medical scrub disclosed in this document provides the solution.

DISCLOSURE OF THE INVENTION [Para 10] It is an object of the bacteriostatic pocket medical scrub to reduce or eliminate bacteria. Reducing bacteria transformation is important to prevent infections from passing from one person to another. In a hospital setting, a doctor will use a stethoscope or other medical devices and tools to check different patients and between using the stethoscope they will place the stethoscope in a pocket where bacteria on the stethoscope can be transferred between patients. Storing the stethoscope in a container or the bacteriostatic area of the garment will prevent the transfer of bacteria between patients. [Para 11] It is an object of the bacteriostatic pocket medical scrub to be in the form of a pocket for storing frequently used non-disposable medical equipment. A stethoscope easily forms into an elongated shape with the bell and diaphragm having a weighted end that easily pulls the remainder of the stethoscope into an elongated pocket. This pulls all or nearly all of the stethoscope into the elongated pocket to prevent or eliminate bacteria on the stethoscope to prevent transfer between patients. The pocket will have a flap, snap or button that separates the ear tips to prevent the entire stethoscope from being pulled into the pocket. [Para 12] It is an object of the bacteriostatic pocket medical scrub for the pocket to have layers of copper fabric mesh. Copper and copper mesh kill molecular mechanisms responsible for the antibacterial action of copper have been a subject of intensive research. Scientists are also actively demonstrating the intrinsic efficacy of copper alloy "touch surfaces" to destroy a wide range of microorganisms that threaten public health. [Para 13] It is another object of the bacteriostatic pocket to take the form of a storage case. The storage case is constructed with woven copper with foam pads that ensure contact with items placed within the storage case. The use of copper fabric mesh allows the fabric to easily flex around a stethoscope to increase the surface contact area. Pure thin strands of copper are highly flexible and easily conforms around objects. The thin strands can be flexed many times without failure of the strands. [Para 14] It is still another object of the bacteriostatic pocket medical scrub to stop the spread of nosocomial and hospital acquired diseases continue to rise, causing substantial accidental death, morbidity, and billions annually in lost, wasted revenue. The bacteriostatic pocket medical scrub can sharply decrease unwanted statistics of the transmission of viruses and save lives and money. [Para 15] Various objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.

[Para 22] Item Numbers and Description [Para 23] 14 ear tips 15 binaural [Para 24] 16 tubing 17 bell and diaphragm [Para 25] 18 stethoscope 19 person [Para 26] 20 medical scub 21 shirt [Para 27] 22 pocket 23 pants [Para 28] 24 medical device 28 stitching [Para 29] 29 snap /button 30 elongated pocket [Para 30] 31 upper seam 32 clothing fabric [Para 31] 33 Polyester / Copper 34 Polyester / Copper [Para 32] 35 outer cloth fabric 40 flap [Para 33] 41 snap 50 square pocket [Para 34] 51 pocket patch 52 rectangular pocket [P 35] 53 k t 60 t [Para 36] 61 top lid 62 bottom lid [Para 37] 63 latch 64 latch [Para 38] 65 handle 66 copper mesh fabric [Para 39] FIG.1 shows a perspective view of a medical scubs 20 with a bacteriostatic elongated pocket 30. The pocket forms a hollow chamber where any tool or device can be stored. In this preferred embodiment the elongated pocket is lined or formed with a material made of 71% polyester and 29% copper. 1000 ppm’s of cooper is bacteriostatic against bacterium species. The medical scubs 20 is shown with a shirt 21 and a pants 23 set having a draw string. The shirt 21 is shown with a single pocket 22, but could have no pockets or more than one pocket on the shirt 21. [Para 40] The elongated pocket 30, and some or all of the pockets, can be lined with a copper fibers, filaments, or dust, that utilizes a conversion factor from liquid to solid formula of 1gm per cm 2 is woven or secured inside of the pocket. The copper, this will function as a self- functioning autoclave like device, where the bacteria and colonization of all hospital acquired bacterium species will be inhibited, thus, preventing colonization, growth, and transmission of the bacteria from commonly used hospital devices. In one preferred embodiment, the material is made of 71% polyester and 29% copper, but copper content as low as 20% is contemplated. [Para 41] This elongated pocket 30 having dimensions of around 4 inches width x 21 inches in length is shown configured for a stethoscope with the bell and diaphragm 17 in the lower area of the elongated pocket 30. It is contemplated that the width of the pocket can be between 1 and 8 inches and the length can be between 4 and 24 inches. A stethoscope is a common tool known to transmit invisible pathogens from patient to patient and to other hospital workers. In this figure the ends of the binaural and the ear tips 14 of the stethoscope 18 are shown extending from the top of the upper seam 31 of the elongated pocket 30. The figure also shows a snap or button 29 that closes the elongated pocket 30 and separates the ends of the binaural 15 to keep the stethoscope 18 from drooping into the elongated pocket 30. While a snap or button is shown, it could also be a hook-and-loop fastener or a magnetic closure. Other embodiments of the pocket closure are shown and described with other figures herein. [Para 42] Copper and its alloys such as, but not limited to brasses, bronzes, copper Nickle, copper-nickel-zinc, and others) are natural antimicrobial materials. Ancient civilizations exploited the antimicrobial properties of copper long before the concept of microbes became understood in the nineteenth century. In addition to several copper medicinal preparations, it was also observed centuries ago that water contained in copper vessels or transported in copper conveyance systems was of better quality (i.e., no or little visible slime or biofouling formation) than water contained or transported in other materials. [Para 43] The antimicrobial properties of copper are still under active investigation. Molecular mechanisms responsible for the antibacterial action of copper have been a subject of intensive research. Scientists are also actively demonstrating the intrinsic efficacy of copper alloy "touch surfaces" to destroy a wide range of microorganisms that threaten public health. Copper works several ways, on the cell wall, interferes with protein synthesis, and it works inhibiting bacterium, virus, and fungi, using copper ionic properties. [Para 44] FIG.2 shows an opposite side of the medical scrubs 20 that are shown in FIG.1 with a variety of other bacteriostatic pockets. The shirt 21 is shown with a chest pocket 22. While a single pocket is shown none or more than one pocket can be used. It is contemplated that this pocket 22 could be used to store glasses that pass into an antimicrobial pocket when the glasses are not being used. This pants 23 leg has a variety of different pocket configurations for holding medical devices 24. [Para 45] One or more of these pockets can be bacteriostatic pockets where medical devices 24 are placed into the bacteriostatic pockets when not being used. This embodiment shows one contemplated configuration of pockets with a square pocket 50 sewn or otherwise secured to the pants 23. A pocket patch 51 is shown with a variety of different pockets including, but not limited to rectangular pockets 52 and a square pocket 53. The pocket patch 51 allows for the pockets to be produced separately from the pants 23 and then added in a final step of assembly. This also allows for more customization based upon the needs /use of the scrubs. While the words square, rectangular and elongated are used to describe the shape of the can take any regular or irregular shape to hold medical devices 24. [Para 46] FIG.3 shows a side view of the pants 23 of the medical scrubs and FIG.4 shows a cross-section of a pocket. In figure 3 the stethoscope is shown with the bell and diaphragm 17 in the bottom of the elongated pocket 30. The binaural 15 tubes are shown extending out of the elongated pocket 30 and crossing under a flap 40 that is secured with a snap 41. While a snap or button is shown, it could also be a hook-and-loop fastener or a magnetic closure. The flap 40 and snap 41 keeps the ear tips 14 separated and keeps the stethoscope from falling into the elongated pocket 30. The tubing 16 connects from the binaural 15 to the bell and diaphragm 17. The tubing 16 and the binaural 15 most often makes contact with a person or their clothing and any patient discharge. [Para 47] Stitching 28 closes the bottom and sides of the elongated pocket 30. In figure 4 the construction of the bacteriostatic pocket is most visible. The bacteriostatic pocket is sewn or otherwise secured to the clothing fabric 32. A layer of polyester copper 33 is sewn or otherwise secured to the clothing fabric 32. The other inside of the bacteriostatic pocket has another layer of polyester copper 34 that is covered with an outer cloth fabric 35. Copper inhibits many bacterial propagations or is inhibited in concentrations above 10 g/L. Propagation and / or inhibiting the bacteria are increased by prolonged exposure, and periods of time beyond 10 minutes with ascorbic acid will essentially stop bacteria. The pocket forms a hollow chamber where any tool or device can be stored to inhibit and decrease bacterium grown and colonization of all common bacterial species. [Para 48] The 3-dimensional structure of proteins can be altered by copper, so that the proteins can no longer perform their normal functions. The result is inactivation of bacteria or viruses. Copper based materials form radicals that inactivate viruses. Copper may disrupt enzyme structures, and functions by binding to sulfur- or carboxylate-containing groups and amino groups of proteins. Microbes require copper-containing enzymes to drive certain vital thereby inhibiting their activities. Researchers believe that excess copper has the potential to disrupt cell function both inside cells and in the interstitial spaces between cells, probably acting on the outer envelope of cells. [Para 49] FIG.5 shows a bacteriostatic storage case 60. The case has a plastic composite or metal outer shell. In this embodiment the storage case 60 has upper latch 63 and lower latch 64 and a carrying handle 65. Within the outer case, in both the upper and lower portions of the storage case 60, is a memory foam, or other pliable foam rubber, padding or similar material that can conform around objects within the case 60. Placed over the top of foam is a copper fabric mesh 66 within the top lid 61 and the bottom lid 62. The copper fabric mesh is a fabric, mesh, filaments or other pliable form of construction that forms around objects within the case 60 under pressure of the underlying foam padding. [Para 50] Upon closing the storage case 60 the interior creates a pocket around tools or the stethoscope 18 that benefit from bacteriostatic processing. The bacteriostatic process takes about 2 hours to wipe out all gram negative and gram-positive bacterium. The storage case 60 allows equipment to be stored and sterilized and can be used in hospitals and with healthcare workers that are exposed to invisible pathogens and creates a bacteriostatic pocket storage device and clothing protection that will reduce or eliminate the transmission and delivery of commonly transferred bacterium. [Para 51] Copper alloy surfaces have intrinsic properties to destroy a wide range of microorganisms. In the interest of protecting public health, especially in healthcare environments with their susceptible patient populations. For the most part, the bacterial kill rate of copper alloys increased with increasing copper content of the alloy. Once surfaces are contaminated with virus particles, fingers can transfer particles to up to seven other clean surfaces. Because of copper's ability to destroy influenza A virus particles, copper can help to prevent cross-contamination of this viral pathogen. [Para 52] Thus, specific embodiments of a bacteriostatic pocket medical scrub have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.

INDUSTRIAL APPLICABILITY [Para 53] The industrial applicability relates to a bacteriostatic pocket medical scrub includes a bacteriostatic pocket that reduces or eliminates bacteria and viruses on items placed within the pocket.
