Description:
ABSORBENT ARTICLE, ABSORBENT SYSTEM AND DISPENSING SYSTEM

Technical Field

The present disclosure refers to an absorbent article, an absorbent system including a plurality of absorbent articles, and a dispensing system including the absorbent system.

Background

Isolation of a working area and management of a dental fluid, such as moisture, blood, and saliva, in a mouth of a patient is generally a challenge for dental practitioners. Multiple approaches have been taken over the years to address this challenge. Conventional solutions, for example, rubber dams, or cotton rolls, have various drawbacks, such as discomfort for the patient, difficulty of placement in the mouth of the patient, or eventual saturation, and a need to be frequently replaced. Generally, the rubber dams are commonly used by the dental practitioners. However, the rubber dams are difficult to use and can cause discomfort to the patient. Therefore, the rubber dams are utilized in only about 15% of clinical cases. Further, the cotton rolls are typically positioned between a tooth and cheek, or between the teeth and a tongue of the patient. The cotton rolls get saturated rapidly. Further, the cotton rolls may become slippery and uncomfortable to work with once saturated. Therefore, the cotton rolls may need to be frequently replaced.

Thus, it may be desirable to have a simple, comfortable, and easy to set up solution to isolate the working area and manage the dental fluid in the mouth of the patient.

In some embodiments, the interconnect member 103 (shown in FIGS. 1A and IB) joins the outer surfaces 204 of the at least two absorbent pads 202.

Each absorbent pad 202 includes an outer layer 206. Each absorbent pad 202 further includes an inner layer 205 disposed adjacent to the outer layer 206. The outer layer 206 defines the outer surface 204.

As used herein, the term “layer” refers to a thickness of material that has a relatively consistent formula. A given layer may be combined or connected to other layers. A layer may be either partially or fully continuous as compared to adjacent layers. A given layer may be partially or fully coextensive with the adjacent layers.

As used herein, the term “inner layer” refers to a layer which does not reside on the outer surface 204 of the absorbent pad 202. The inner layer 205 may include a single layer or may be multi-layered.

The outer layer 206 of the absorbent pad 202 is folded upon itself to form a first portion 240A and a second portion 240B connected to the first portion 240A, such that the inner layer 205 is enclosed by the outer layer 206.

The outer layer 206 is made of a liquid permeable material. In some embodiments, the outer layer 206 is hydrophilic. The outer layer 206 may therefore readily allow the liquid to pass to the inner layer 205 disposed adjacent to the outer layer 206. The inner layer 205 includes the absorbent material configured to absorb the liquid. In some embodiments, the outer layer 206 is tear resistant. In such embodiments, the absorbent pad 202 may be placed in the oral environment without tearing or perforating of the outer layer 206 due to contact with the teeth of the patient. However, in some embodiments, on addition of an additive, the outer layer 206 may turn from hydrophilic to hydrophobic. The additive may be added to the outer layer 206 once absorbent pad 202 is saturated with the liquid.

In some embodiments, the outer layer 206 may have an average thickness Tl. In some embodiments, the average thickness Tl may be greater than about 0.1 mm, greater than about 0.25 mm, greater than about 0.5 mm, greater than about 0.75 mm, or as per desired application attributes. In some embodiments, the inner layer 205 has a maximum thickness T2. In some embodiments, the maximum thickness T2 may be greater than about 5 mm, greater than about 7.5 mm, greater than about 10 mm, greater than about 12 mm, or as per desired application attributes. In the illustrated embodiment of FIG. 2A, the average thickness Tl of the outer layer 206 is less than the maximum thickness T2 of the inner layer 205. In some embodiments, the average thickness Tl of the outer layer 206 may be less than the maximum thickness T2 of the inner layer 205. However, in some other embodiments, the average thickness Tl of the outer layer 206 may be substantially equal to the thickness T2 of the inner layer 205.

In some embodiments, each absorbent pad 202 has a maximum height H3. In some embodiments, the maximum height H3 may be greater than about 2 mm, greater than about 4 mm, greater than about 5 mm, greater than about 6 mm, greater than about 8 mm, greater than about 10 mm, greater than about 12 mm, or as per desired application attributes. In some embodiments, the maximum height H3 of the absorbent pad 202 may be substantially similar to one of the heights Hl, H2 of the absorbent pads 102A, 102B shown in FIG. IB. However, in some other embodiments, the maximum height H3 and the heights Hl, H2 may be different.

In the illustrated embodiment of FIGS. 2A and 2B, the absorbent pad 202 has a rectangular shape. However, the absorbent pad 202 may have any suitable shape, as per desired application attributes.

Each absorbent pad 202 further includes a seal 207 formed between the first portion 240A and the second portion 240B. The seal 207 may be formed using any sealing method, such as heat sealing, ultrasonic sealing, frictional heating, adhesive bonding, stitching, and so forth.

FIG. 3 illustrates a schematic cross-sectional view of an absorbent article 301. The absorbent article 301 may be substantially similar to the absorbent article 101 illustrated in FIGS. 1A and IB. The absorbent article 301 includes at least two absorbent pads 302A, 302B spaced apart from each other. Each absorbent pad 302A, 302B further includes an outer surface 304A, 304B. Specifically, the absorbent pad 302A includes the outer surface 304A. The absorbent pad 302B includes the outer surface 304B. The absorbent article 301 further includes an interconnect member 303. The interconnect member 303 joins the outer surfaces 304A, 304B of the at least two absorbent pads 302A, 302B.

Each absorbent pad 302A, 302B includes a first layer 308 made of a liquid permeable material. Each absorbent pad 302A, 302B further includes a second layer 309. Each absorbent pad 302A, 302B further includes a third layer 310 disposed between the first layer 308 and the second layer 309. The first layer 308 and the second layer 309 together define the outer surface 304A, 304B. The third layer 310 is enclosed by the first layer 308 and the second layer 309.

In some embodiments, the first layer 308 is hydrophilic. The first layer 308 may therefore readily allow the liquid to pass to the third layer 310 disposed adjacent to the first layer 308. The third layer 310 includes the absorbent material configured to absorb the liquid. The absorbent material may include one or more of superabsorbent particles, superabsorbent fibers, cellulose ethyl sulfonate, carboxymethyl cellulose, sodium polyacrylate, hydrogel particles, hydrogel-based non-woven material, cellulose foam, hydrogel polyurethane, silicone foam, and polyurethane foam. However, in some embodiments, on addition of the additive, the first layer 308 may turn from hydrophilic to hydrophobic. The additive may be added to the outer layer 206 once absorbent pad 202 is saturated with the liquid.

In some embodiments, the first layer 308 is tear resistant. In such embodiments, the absorbent article 301 may be placed in the oral environment without tearing or perforating of the first layer 308 due to contact with the teeth of the patient.

In some embodiments, the second layer 309 is made of a liquid permeable material. The second layer 309 may therefore allow the liquid from the third layer 310 to pass through. In some other embodiments, the second layer 309 is made of a liquid impermeable material. In some embodiments, the second layer 309 is hydrophobic. In such embodiments, the second layer 309 may not allow the liquid from the third layer 310 to pass through and therefore, trap the liquid in the third layer 310. Thus, the second layer 309 may ensure that a flow of the liquid in each absorbent pad 302A, 302B is unidirectional. Each absorbent pad 302A, 302B includes a seal 307A, 307B formed between the first layer 308 and the second layer 309. Specifically, the absorbent pad 302A includes the seal 307A. The absorbent pad 302A includes the seal 307B. The seals 307A, 307B may be formed using any sealing method, such as heat sealing, ultrasonic sealing, frictional heating, adhesive bonding, stitching, and so forth. In some embodiments, at least a portion of the seals 307A, 307B may join the interconnect member 303 to each of the absorbent pads 302A, 302B.

The interconnect member 303 is stretchable. In some embodiments, the interconnect member 303 is made of an elastomeric material. In some embodiments, the elastomeric material is rubber. In some embodiments, the interconnect member 303 is made of a liquid impermeable material. In some embodiments, the interconnect member 303 includes at least one of polyurethane, styrene block copolymers, polyester elastomers, and elastomeric polyolefins. In some embodiments, the interconnect member 303 is made of a non-woven material.

FIGS. 4A and 4B depict a schematic top view and a schematic perspective view, respectively, of an absorbent article 401. The absorbent article 401 is substantially similar to the absorbent article 101 illustrated in FIG. 1 A. However, the interconnect member 103 includes one or more through apertures 411. Each of the one or more through apertures 411 is configured to receive at least one tooth.

In the illustrated embodiment of FIGS. 4A and 4B, the interconnect member 103 includes only one through aperture 411. In some embodiments, the through aperture 411 may be configured to receive one tooth. In some embodiments, the through aperture 411 may be configured to receive more than one tooth. In the illustrated embodiment of FIGS. 4A and 4B, the through aperture 411 is substantially circular in shape and has a radius R. In some embodiments, the radius R may be less than about 0.25 cm, less than about 0.5 cm, or as per desired application attributes.

In some other embodiments, multiple through apertures (such as, the through aperture 411) may be present. In some embodiments, each of the multiple through apertures may be configured to receive one tooth. In some embodiments, the multiple through apertures may be similar in size and shape. In some other embodiments, the multiple through apertures may be different in size and shape. The size and shape of the one or more through apertures 411 may vary based on the desired application attributes.

FIGS. 5A and 5B depict a schematic top view and a schematic perspective view, respectively, of an absorbent article 501. The absorbent article 501 is substantially similar to the absorbent article 401 illustrated in FIGS. 4A and 4B. However, the interconnect member 103 includes one or more through apertures including a slit 511. The slit 511 is configured to receive at least one tooth. In some embodiments, the slit 511 may be configured to receive more than one tooth. In the illustrated embodiment of FIGS. 5 A and 5B, the slit 511 is substantially oval in shape and has a maximum radius R1 and a minimum radius R2. In some embodiments, the maximum radius R1 may be less than about 0.1 cm, less than about 0.25 cm, less than about 0.5 cm, less than about 0.75 cm, or as per desired application attributes. In some embodiments, the minimum radius R2 may be less than about 0.1 cm, less than about 0.25 cm, less than about 0.5 cm, or as per desired application attributes. FIG. 6A depicts a schematic view of a lower jaw 640 of the patient and the absorbent article 401 in use. The liquid, such as blood, saliva and/or water, may be produced and accumulated in the lower jaw 640. In some other embodiments, the absorbent article 401 may be placed in an upper jaw (not shown) of the patient. The interconnect member 103 includes the through aperture 411 as shown in FIG. 4A. When in use, the interconnect member 103 is stretched and placed over at least one tooth 650 to be worked on by the dental clinician. Specifically, the interconnect member 103 is stretched and placed over the at least one tooth 650 such that the through aperture 411 may surround and secure the at least one tooth 650. In some embodiments, the through aperture 411 may take a shape of the at least one tooth 650. In some embodiments, the interconnect member 103 is stretched and placed over the at least one tooth 650 such that the multiple through apertures (not shown) surround and secure a corresponding tooth. Specifically, the at least one tooth 650 may project through the through aperture 411 providing a working area visibility and accessibility to the dental clinician.

The absorbent pads 102A, 102B may be placed on either side of the at least one tooth 650. This placement of the absorbent pads 102A, 102B and the interconnect member 103 of the absorbent article 401 may isolate the at least one tooth 650 and may ensure that the liquid is absorbed from the oral environment efficiently and without discomfort to the patient. The absorbent article 401 may further prevent the liquid from entering a throat of the patient. The absorbent article 401 may thereby keep the oral environment dry and provide the working area visibility and accessibility to the dental clinician.

In the illustrated embodiments of FIG. 6A, the absorbent article 401 is shown. However, in other embodiments, the absorbent articles 101 and 301 (shown in FIGS. 1A and 3, respectively) may also be used in a similar manner. When using the absorbent articles 101 and 301, the dental clinician may penetrate or puncture the interconnect member 103, 303 to form the through aperture 411 before stretching and placing the interconnect member 103, 303 over the at least one tooth 650. In some embodiments, the dental clinician may penetrate or puncture the interconnect member 103, 303 to form the multiple through apertures to receive the corresponding tooth.

FIG. 6B depicts a schematic view of the lower jaw 640 of the patient and the absorbent article 501 in use. In some embodiments, the absorbent article 501 may be placed in the upper jaw (not shown) of the patient. The interconnect member 103 includes the slit 511, as shown in FIG. 5 A. When in use, the interconnect member 103 is stretched and placed over at least one tooth to be worked on by the dental clinician. Specifically, the interconnect member 103 is stretched and placed over the at least one tooth such that the slit 511 may surround and secure the at least one tooth. In the illustrated embodiment of FIG. 6B, the slit 511 surrounds and secures two teeth 660, 670. In some embodiments, the slit 511 may take a shape of the teeth 660, 670. However, in some other embodiments, the slit 511 may surround and secure any one of the teeth 660, 670. Specifically, the teeth 660, 670 may project through the slit 511 providing the working area visibility and accessibility to the dental clinician.

The absorbent pads 102A, 102B are placed on the either side of the teeth 660, 670. This placement of the absorbent pads 102A, 102B and the interconnect member 103 of the absorbent article 501 may isolate the teeth 660, 670 and may ensure that the liquid is absorbed from the oral environment efficiently and without discomfort to the patient. The absorbent article 501 may further prevent the liquid from entering the throat of the patient. The absorbent article 501 may thereby keep the oral environment dry and provide the working area visibility and accessibility to the dental clinician.

In the illustrated embodiments of FIG. 6B, the absorbent article 501 is shown. However, in other embodiments, the absorbent articles 101 and 301 may also be used in a similar manner. When using the absorbent articles 101 and 301, the dental clinician may penetrate or puncture the interconnect member 103, 303 to form the slit 511 before stretching and placing the interconnect member 103, 303 over the teeth 660, 670.

FIGS. 7A to 7G illustrate schematic views of various absorbent pads having different shapes. Specifically, FIGS. 7A to 7G depict respective absorbent pads 602A, 602B, 602C, 602D, 602E, 602F, 602G. The absorbent pad 602A has a substantially cuboidal shape. The absorbent pad 602B has a pyramidal shape. The absorbent pad 602C has a prismatic shape. The absorbent pad 602D has a spherical shape. The absorbent pad 602E has a substantially L-shape. The absorbent pad 602F has a cubical shape. The absorbent pad 602G a triangular pyramidal shape.

In some embodiments, the absorbent pads 602A, 602B, 602C, 602D, 602E, 602F, 602G may be filled with the absorbent material through an injection molding process.

Similarly, the absorbent pads 602A, 602B, 602C, 602D, 602E, 602F, 602G may have any size depending upon a size of the mouth of the patient. For example, if the patient is a child, a size of the absorbent pad 602A, 602B, 602C, 602D, 602E, 602F, 602G may be relatively smaller.

FIGS. 8 A and 8B depict a schematic top and a schematic perspective view, respectively of an absorbent article 701. The absorbent article 701 is substantially similar to the absorbent article 101 illustrated in FIGS. 1 A and IB. The absorbent article 701 includes at least two absorbent pads 702A, 702B spaced apart from each other. However, as illustrated in FIGS. 8 A and 8B, each absorbent pad 702A, 702B is arc-shaped, such that a first absorbent pad 702A of the at least two absorbent pads 702A, 702B forms an inner arc 713 and a second absorbent pad 702B of the at least two absorbent pads 702A, 702B forms an outer arc 715. The inner arc 713 and the outer arc 715 may correspond to a shape of the lower jaw 640 (shown in FIGS. 6A and 6B) of the patient. Therefore, the absorbent article 701 may fit in the mouth of the patient with ease and without causing discomfort to the patient.

Each absorbent pad 702A, 702B further includes an outer surface 704A, 704B. An interconnect member 703 joins the outer surfaces 704A, 704B of the at least two absorbent pads 702A, 702B. In some embodiments, the interconnect member 703 includes one or more through apertures 711A, 71 IB, 711C, 71 ID, 71 IE (collectively, one or more through apertures 711). Each of the one or more through apertures 711 is configured to receive at least one tooth. In the illustrated embodiment of FIGS. 8A and 8B, the interconnect member 703 includes five through apertures 711. However, in some other embodiments, the interconnect member 703 may include more than five through apertures 711. In some other embodiments, the interconnect member 703 may include less than five through apertures 711. In some other embodiments, the interconnect member 703 may include one through aperture 711.

The first absorbent pad 702A and the second absorbent pad 702B of the absorbent article 701 may cover either side of the at least one tooth while exposing only the at least one tooth to the dental clinician. The absorbent article 701 may thereby keep the oral environment dry and may further provide the working area visibility and accessibility to the dental clinician.

FIG. 8C illustrates a schematic top view of an absorbent article 801. The absorbent article 801 is substantially similar to the absorbent article 701. However, the absorbent article 801 further includes an inner member 816 attached to the first absorbent pad 702A at least partially along the inner arc 713. In some embodiments, the inner member 816 is stretchable. In some embodiments, the inner member 816 is made of a liquid impermeable material. In some embodiments, the interconnect member 703 and the inner member 816 of the absorbent article 701 are made of a similar material. The inner member 816 may be placed over a tongue of the patient. The inner member 816 may cover the tongue of the patient and may protect the patient from sharp tools used by the dental clinician. The inner member 816 may further restrict the flow of the liquid to the tongue of the patient. The inner member 816 may further help to keep the tongue of the patient away from the at least one tooth.

FIGS. 9A, 9B and 9C illustrate absorbent pads 902A, 902B, 902C, respectively. The absorbent pads 902A, 902B, 902C are substantially similar to the absorbent pad 102A of FIG. 1A. The absorbent pads 902A, 902B, 902C include outer surfaces 914A, 914B, 914C, respectively.

Further, the absorbent pad 902C incudes the wire mesh 917C disposed on the outer surface 914C. In some embodiments, each of the wire meshes 917A, 917B, 917C may include ductile wires. The wire meshes 917A, 917B, 917C may help to conform the respective absorbent pads 902A, 902B, 902C to a desired shape to fit in the mouth of the patient. In other words, the wire meshes 917A, 917B, 917C may help to deform and alter a shape of the respective absorbent pads 902A, 902B, 902C to conform to different inner sizes and shapes of the mouth. The absorbent pads 902A, 902B, 902C including the wire meshes 917A, 917B, 917C may provide a good coverage in an area where the liquid, such as blood, saliva and/or water, is produced and accumulated, and may therefore provide an efficient absorption of the liquid from the oral environment. In some other embodiments, the wire meshes 917A, 917B, 917C may be embedded in the respective absorbent pads 902A, 902B, 902C. For example, the wire meshes 917A, 917B, 917C may be embedded the third layer 310 (shown in FIG. 3). In such embodiments, the wire meshes 917A, 917B, 917C may hold the absorbent material in place. In some other embodiments, the wire meshes 917A, 917B, 917C may be embedded in the first layer 308 (shown in FIG. 3) and/or the second layer 309 (shown in FIG. 3).

FIG. 10 illustrates a schematic view of an absorbent article 1001. The absorbent article 1001 is substantially similar to the absorbent article 701 of FIG. 8A. However, at least one of the two absorbent pads 702A, 702B includes a tube 1013 in fluid communication with the absorbent material . The tube 1013 is configured to be attached to a suction source 1012. The suction source 1012 may create a negative pressure inside the tube 1013. In some embodiments, the tube 1013 is flexible and may easily bend and adapt to other shapes. The suction source 1012 may provide active suction to remove the excess liquid from the at least one of the two absorbent pads 702A, 702B once the at least one of the two absorbent pads 702A, 702B is saturated. In some embodiments, the suction source 1012 may be placed away from the absorbent article 701.
