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.

DETAILED DESCRIPTION
In the following description, reference is made to the accompanying figures that form a part thereof and in which various embodiments are shown by way of illustration. It is to be understood that other embodiments are contemplated and may be made without departing from the scope or spirit of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense.
As recited herein, all numbers should be considered modified by the term “about”. As used herein, “a,” “an,” “the,” “at least one,” and “one or more” are used interchangeably. As used herein, layers, components, or elements may be described as being adjacent to one another. Layers, components, or elements can be adjacent one another by being in direct contact, by being connected through one or more other components, or by being held next to one another or attached to one another. Layers, components, or elements that are in direct contact may be described as being immediately adjacent.
The present disclosure relates to an absorbent article including at least two absorbent pads spaced apart from each other and an interconnect member. Each absorbent pad includes an absorbent material configured to absorb a liquid. Each absorbent pad further includes an outer surface. The interconnect member joins the outer surfaces of the at least two absorbent pads. The interconnect member is stretchable. The present disclosure further relates to an absorbent system including a plurality of absorbent articles and at least one line of weakness. The present disclosure further relates to a dispensing system including the absorbent system and a dispenser.
The absorbent article of the present disclosure may be used to isolate a working area and to absorb the liquid in an oral environment within a mouth of a patient. The liquid may include saliva, water, and blood. The absorbent article may further prevent the liquid from entering a throat of the patient. Conventional methods of isolation of the working area or absorption of the liquid in the oral environment include use of rubber dams, cotton rolls, or suction devices. Conventional methods 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.
The absorbent pads may be molded into a desired shape to fit in the mouth of the patient. The absorbent pads may further be formable. Therefore, the absorbent pads may fit in the mouth of the patient without causing any discomfort while providing an efficient absorption of the liquid from the oral environment. Further the absorbent pads may have curved or rounded edges. The curved edges may prevent any bruises or injures to oral tissues in the oral environment of the patient.
When using the absorbent articles, a dental clinician may penetrate or puncture the interconnect member to form a through hole or a slit and place the interconnect member over a tooth in the working area. As the interconnect member is stretchable, the through hole or the slit may surround and secure the tooth. The interconnect member of the absorbent article may therefore help to isolate the working area and may provide the dental clinician with visibility and accessibility to the working area.
The absorbent article of the present disclosure may be simple to manufacture, comfortable to the patient, and easy to set up. The absorbent article of the present disclosure can be used to isolate the working area and to absorb the liquid in the oral environment.
Further, the dental clinician may detach or tear one or more absorbent articles from the plurality of absorbent articles. For ease of detaching or tearing, the absorbent system may have at least one line of weakness.
In addition, the dispensing system may further provide ease and convenience to the dental clinician to dispense the absorbent articles, according to application requirements.
FIGS. 1A and 1B illustrate a schematic top view and a schematic perspective view, respectively, of an absorbent article 101. The absorbent article 101 may be used by a dental clinician to keep an oral environment dry. The dental clinician may be a professional specialized in addressing an oral health of a patient.

As used herein, the term “absorbent material” refers to a material with an ability to absorb a liquid (such as, saliva, water, and blood). The absorbent material may have a suitable absorption rate as per desired application attributes. As used herein, the term “absorption rate” refers to a volume of liquid absorbed per unit time, for example, milliliters per second. In some embodiments, the absorption of the liquid may not significantly increase a size or a volume of the absorbent pads 102A, 102B. However, in some other embodiments, the absorption of the liquid may increase the size or the volume of the absorbent pads 102A, 102B.
The absorbent article 101 further includes an interconnect member 103. The interconnect member 103 joins the outer surfaces 104A, 104B of the at least two absorbent pads 102A, 102B. In some embodiments, the interconnect member 103 joins the outer surfaces 104A, 104B of the at least two absorbent pads 102A, 102B by one or more of an adhesive, heat sealing, stitching, or frictional heating.
Furthermore, the interconnect member 103 is stretchable. In some embodiments, the interconnect member 103 is made of an elastomeric material. In some embodiments, the elastomeric material is rubber. In some embodiments, the interconnect member 103 is made of a liquid impermeable material. In some embodiments, the interconnect member 103 includes at least one of polyurethane, styrene block copolymers, polyester elastomers, and elastomeric polyolefins. In some embodiments, the interconnect member 103 is made of a non-woven material.
In some embodiments, each absorbent pad 102A, 102B has a length L1, L2. Specifically, the absorbent pad 102A has the length L1. The absorbent pad 102B has the length L2.

In some embodiments, a shape of each absorbent pad 102A, 102B is at least one of cylindrical, pyramidal, cuboidal, and polyhedral.
In some embodiments, the interconnect member 103 has a width W3. In some embodiments, the width W3 may be less than about 0.25 cm, less than about 0.4 cm, less than about 0.5 cm, less than about 0.75 cm, less than about 1 cm, less than about 1.5 cm, less than about 2 cm, less than about 2.5 cm, or as per desired application attributes. In the illustrated embodiment of FIG. 1A, the width W3 of the interconnect member 103 is less than the widths W1, W2 of the absorbent pads 102A, 102B. However, in some other embodiments, the width W3 of the interconnect member 103 may be substantially equal to the widths W1, W2 of the absorbent pads 102A, 102B. In some other embodiments, the width W3 of the interconnect member 103 may be greater than the widths W1, W2 of the absorbent pad 102A, 102B. The width W3 may correspond to a normal unstretched width of the interconnect member 103.
In the illustrated embodiment of FIGS. 1A and 1B, a length of the interconnect member 103 is substantially equal to the lengths L1, L2 of the of the absorbent pads 102A, 102B. However, in some other embodiments, the length of the interconnect member 103 may be less than the lengths L1, L2 of the of the absorbent pads 102A, 102B.
As illustrated in FIGS. 1A and 1B, each absorbent pad 102 A, 102B may have curved or rounded edges. The curved edges may prevent any bruises or injures to oral tissues in the oral environment of the patient.
FIGS. 2A and 2B illustrate a schematic cross sectional view and a schematic top view, respectively, of an absorbent pad 202. The absorbent pad 202 may be substantially similar to the absorbent pads 102A, 102B illustrated in FIGS. 1A and 1B. The absorbent pad 202 includes an outer surface 204. In some embodiments, the absorbent article 101, as illustrated in FIGS. 1A and 1B, may include at least two absorbent pads 202. In some embodiments, the interconnect member 103 (shown in FIGS. 1A and 1B) 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 T1. In some embodiments, the average thickness T1 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 T1 of the outer layer 206 is less than the maximum thickness T2 of the inner layer 205. In some embodiments, the average thickness T1 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 T1 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 H1, H2 of the absorbent pads 102A, 102B shown in FIG. 1B. However, in some other embodiments, the maximum height H3 and the heights H1, 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 1B. 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. 1A. 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. 5A 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.

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.

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, 711B, 711C, 711D, 711E (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.
