Description

Technical Field

[0001] The present disclosure relates to absorbent articles, an absorbent system including a plurality of absorbent articles, and a dispensing system including the absorbent system.

Background Art

[0002] Isolation of the working area and management of dental fluids such as moisture, blood, and saliva in the patient's oral cavity are generally challenges for dentists. To address this challenge, multiple approaches have been taken over the years. Conventional solutions, such as rubber dams or cotton rolls, have various drawbacks, such as discomfort for the patient, difficulty in placement within the patient's oral cavity, or eventual saturation and the need for frequent replacement. Generally, rubber dams are commonly used by dentists. However, rubber dams are difficult to use and may cause discomfort to the patient. Thus, rubber dams are utilized in only about 15% of clinical cases. Further, cotton rolls are typically placed between the patient's teeth and cheek or between the teeth and tongue. Cotton rolls saturate quickly. Further, cotton rolls become slippery once saturated, which may make the procedure uncomfortable. Thus, cotton rolls may need to be replaced frequently.

[0003] Thus, there may be a desire to have a simple, comfortable, and easy-to-setup solution for isolating the working area and managing dental fluids in the patient's oral cavity.

Mode for Carrying Out the Invention

[0009] In the following description, reference is made to the accompanying drawings, which form part of the description and in which various embodiments are shown by way of example. It should be understood that other embodiments may be envisioned and implemented without departing from the scope or spirit of the present disclosure. Therefore, the following mode for carrying out the invention is not to be construed in a limiting sense.

[0010] All numbers mentioned herein shall be deemed to be modified by the term “about.” In this specification, “a,” “an,” “the,” “at least one,” and “one or more” are interchangeable. In this specification, layers, components, or elements may be described as adjacent to one another. Layers, components, or elements may be adjacent to one another by direct contact, by being connected through one or more other components, or by being held or attached adjacent to one another. Layers, components, or elements that are in direct contact may be described as directly adjacent.

[0011] This disclosure relates to an absorbent article comprising at least two absorbent pads spaced apart from each other and an interconnecting member. Each absorbent pad comprises an absorbent material configured to absorb liquid. Each absorbent pad further comprises an outer surface. The interconnecting member joins the outer surfaces of at least two absorbent pads. The interconnecting member is expandable and contractible. This disclosure further relates to an absorbent system comprising a plurality of absorbent articles and at least one fragile wire. This disclosure further relates to a distribution system comprising an absorbent system and a dispenser.

[0012] The absorbent articles of this disclosure may be used to isolate a work area and absorb liquids in the oral environment of a patient's mouth. Liquids may include saliva, water, and blood. The absorbent articles may further prevent liquids from entering the patient's throat. Conventional methods for isolating a work area or absorbing liquids in the oral environment include the use of rubber dams, cotton rolls, or suction devices. Conventional methods have various drawbacks, such as discomfort for the patient, difficulty in placement in the patient's mouth, eventual saturation, and the need for frequent replacement.

[0013] The absorbent pad can be molded into a desired shape to fit the patient's oral cavity. The absorbent pad may also be moldable. Thus, the absorbent pad can fit the patient's oral cavity without causing any discomfort while providing efficient absorption of liquids from the oral environment. Furthermore, the absorbent pad may have curved or rounded edges. Curved edges can prevent any bruising or damage to oral tissues within the patient's oral environment.

[0014] When using absorbable articles, dental practitioners may penetrate or puncture the interconnecting members to create through-holes or slits and position the interconnecting members over teeth within the work area. Because the interconnecting members are expandable and contractible, the through-holes or slits can surround and secure the teeth. Thus, the interconnecting members of absorbable articles can help isolate the work area and provide dental practitioners with visibility and access to the work area.

[0015] The absorbent articles of this disclosure may be easy to manufacture, comfortable for the patient, and easy to set up. The absorbent articles of this disclosure can be used to isolate work areas and absorb liquids in the oral environment.

[0016] Furthermore, a dental clinician may remove or tear one or more absorbent articles from a group of absorbent articles. To facilitate removal or tearing, the absorbent system may have at least one fragile line.

[0017] In addition, the distribution system can further provide dental clinicians with ease and convenience for distributing absorbable materials in accordance with applicable requirements.

[0018] Figures 1A and 1B show a schematic top view and a schematic perspective view of the absorbent article 101, respectively. The absorbent article 101 may be used by a dental clinician to keep the oral environment dry. The dental clinician may be a professional who specializes in addressing the oral health of patients. The absorbent article 101 includes at least two absorbent pads 102A and 102B that are spaced apart from each other. Each absorbent pad 102A and 102B includes outer surfaces 104A and 104B. Specifically, absorbent pad 102A includes outer surface 104A. Absorbent pad 102B includes outer surface 104B.

[0019] Each absorbent pad 102A, 102B further comprises an absorbent material configured to absorb liquid. In some embodiments, the liquid includes at least one of saliva, water, and blood. In some embodiments, the absorbent material is made of one or more of superabsorbent particles, superabsorbent fibers, cellulose ethyl sulfonate, carboxymethylcellulose, sodium polyacrylate, hydrogel particles, hydrogel nonwoven materials, cellulose foam, hydrogel polyurethane, silicone foam, and polyurethane foam. As used herein, the term “absorbent material” refers to a material having the ability to absorb liquid (such as saliva, water, and blood). The absorbent material may have a suitable absorption rate depending on the desired application attributes. As used herein, the term “absorption rate” refers to the volume of liquid absorbed per unit time, e.g., milliliters / second. In some embodiments, the absorption of liquid does not need to significantly increase the size or volume of the absorbent pads 102A, 102B. However, in some other embodiments, the absorption of liquid may increase the size or volume of the absorbent pads 102A, 102B.

[0020] The absorbent article 101 further includes an interconnecting member 103. The interconnecting member 103 joins the outer surfaces 104A and 104B of at least two absorbent pads 102A and 102B. In some embodiments, the interconnecting member 103 joins the outer surfaces 104A and 104B of at least two absorbent pads 102A and 102B by one or more of the following: adhesive, heat sealing, stitching, or friction heating.

[0021] Furthermore, the interconnecting member 103 is stretchable. In some embodiments, the interconnecting member 103 is made of an elastomer material. In some embodiments, the elastomer material is rubber. In some embodiments, the interconnecting member 103 is made of a liquid-impermeable material. In some embodiments, the interconnecting member 103 includes at least one of polyurethane, styrene block copolymer, polyester elastomer, and elastomer polyolefin. In some embodiments, the interconnecting member 103 is made of a nonwoven fabric material.

[0022] In some embodiments, each absorbent pad 102A, 102B has lengths L1, L2. Specifically, absorbent pad 102A has length L1, and absorbent pad 102B has length L2. In some embodiments, the lengths L1, L2 of absorbent pads 102A, 102B may be less than about 1 centimeter (cm), less than about 2 cm, less than about 3 cm, less than about 4 cm, less than about 5 cm, less than 5.5 cm, or according to desired application attributes. In the embodiment illustrated in Figure 1A, the lengths L1, L2 of absorbent pads 102A, 102B are substantially equal to each other. However, in some other embodiments, the lengths L1, L2 of absorbent pads 102A, 102B may be different to each other. The lengths L1, L2 of absorbent pads 102A, 102B may be such that each absorbent pad 102A, 102B fits easily into the oral environment and is comfortable for the patient.

[0023] In some embodiments, each absorbent pad 102A, 102B has widths W1, W2. Specifically, absorbent pad 102A has width W1, and absorbent pad 102B has width W2. In some embodiments, the widths W1, W2 of absorbent pads 102A, 102B may be greater than about 0.5 cm, greater than about 1 cm, greater than about 2 cm, greater than about 3 cm, or according to desired application attributes. In the embodiment shown in Figure 1A, the widths W1, W2 of absorbent pads 102A, 102B are substantially equal to each other. However, in some other embodiments, the widths W1, W2 of absorbent pads 102A, 102B may be different to each other. The widths W1, W2 of absorbent pads 102A, 102B may be such that each absorbent pad 102A, 102B fits easily into the oral environment and is comfortable for the patient.

[0024] In some embodiments, each absorbent pad 102A, 102B has heights H1, H2. Specifically, absorbent pad 102A has height H1, and absorbent pad 102B has height H2. In some embodiments, the heights H1, H2 of absorbent pads 102A, 102B 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 according to desired application attributes. In the illustrated embodiment of Figure 1B, the heights H1, H2 of absorbent pads 102A, 102B are substantially equal to each other. However, in some other embodiments, the heights H1, H2 of absorbent pads 102A, 102B may be different. The heights H1, H2 of each absorbent pad 102A, 102B may be such that each absorbent pad 102A, 102B fits easily into the oral environment and is comfortable for the patient.

[0025] In the embodiment shown in Figure 1A, each of the absorbent pads 102A and 102B has a rectangular parallelepiped shape. However, the absorbent pads 102A and 102B may have any preferred shape depending on the desired application attributes. In some embodiments, the shape of each absorbent pad 102A and 102B is at least one of cylindrical, pyramidal, rectangular parallelepiped, and polyhedron.

[0026] In some embodiments, the interconnecting 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 2.5 cm, or according to a desired application attribute. In the embodiment shown in Figure 1A, the width W3 of the interconnecting member 103 is smaller than the widths W1 and W2 of the absorbent pads 102A and 102B. However, in some other embodiments, the width W3 of the interconnecting member 103 may be substantially equal to the widths W1 and W2 of the absorbent pads 102A and 102B. In some other embodiments, the width W3 of the interconnecting member 103 may be larger than the widths W1 and W2 of the absorbent pads 102A and 102B. The width W3 may correspond to the normal unstretched width of the interconnecting member 103.

[0027] In the embodiments shown in Figures 1A and 1B, the length of the interconnecting member 103 is substantially equal to the lengths L1 and L2 of the absorbent pads 102A and 102B. However, in some other embodiments, the length of the interconnecting member 103 may be shorter than the lengths L1 and L2 of the absorbent pads 102A and 102B.

[0028] As shown in Figures 1A and 1B, each absorbent pad 102A, 102B may have a curved or rounded edge. A curved edge can prevent any bruising or injury to oral tissues within the patient's oral environment.

[0029] Figures 2A and 2B show a schematic cross-sectional view and a schematic top view of the absorbent pad 202, respectively. The absorbent pad 202 may be substantially the same as the absorbent pads 102A and 102B shown in Figures 1A and 1B. The absorbent pad 202 includes an outer surface 204. In some embodiments, the absorbent article 101 may include at least two absorbent pads 202, as shown in Figures 1A and 1B. In some embodiments, an interconnecting member 103 (shown in Figures 1A and 1B) joins the outer surfaces 204 of at least two absorbent pads 202.

[0030] Each absorbent pad 202 includes an outer layer 206. Each absorbent pad 202 further includes an inner layer 205 positioned adjacent to the outer layer 206. The outer layer 206 defines an outer surface 204.

[0031] As used herein, the term “layer” refers to the thickness of a material having a relatively consistent composition. A given layer may be bonded or connected to other layers. A layer may be partially or completely continuous with respect to an adjacent layer. A given layer may have partially or completely identical extent to an adjacent layer.

[0032] As used herein, the term “inner layer” refers to a layer that is not present on the outer surface 204 of the absorbent pad 202. The inner layer 205 may be a single layer or a multi-layer layer.

[0033] The outer layer 206 of the absorbent pad 202 is folded over itself so that the inner layer 205 is surrounded by the outer layer 206, forming a first portion 240A and a second portion 240B connected to the first portion 240A.

[0034] The outer layer 206 is made of a liquid-permeable material. In some embodiments, the outer layer 206 is hydrophilic. Thus, the outer layer 206 can easily allow liquid to pass through to the inner layer 205, which is positioned adjacent to the outer layer 206. The inner layer 205 contains an absorbent material configured to absorb liquid. In some embodiments, the outer layer 206 is tear-resistant. In such embodiments, the absorbent pad 202 can be placed in the oral environment without tearing or perforation of the outer layer 206 due to contact with the patient's teeth. However, in some embodiments, the outer layer 206 may change from hydrophilic to hydrophobic upon addition of an additive. Once the absorbent pad 202 is saturated with liquid, the additive may be added to the outer layer 206.

[0035] 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 according to 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 according to desired application attributes. In the embodiment shown in Figure 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.

[0036] 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 according to desired application attributes. In some embodiments, the maximum height H3 of the absorbent pad 202 may be substantially the same as one of the heights H1, H2 of the absorbent pads 102A, 102B shown in Figure 1B. However, in some other embodiments, the maximum height H3 may be different from the heights H1, H2.

[0037] In the embodiments shown in Figures 2A and 2B, the absorbent pad 202 has a rectangular shape. However, the absorbent pad 202 may have any preferred shape depending on the desired application attributes.

[0038] Each absorbent pad 202 further includes a sealing portion 207 formed between a first portion 240A and a second portion 240B. The sealing portion 207 may be formed using any sealing method such as heat sealing, ultrasonic sealing, friction heating, adhesive bonding, or suturing.

[0039] Figure 3 shows a schematic cross-sectional view of the absorbent article 301. The absorbent article 301 may be substantially the same as the absorbent article 101 shown in Figures 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 outer surfaces 304A, 304B. Specifically, absorbent pad 302A includes outer surface 304A. Absorbent pad 302B includes outer surface 304B. The absorbent article 301 further includes an interconnecting member 303. The interconnecting member 303 joins the outer surfaces 304A, 304B of at least two absorbent pads 302A, 302B.

[0040] 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 positioned between the first layer 308 and the second layer 309. The first layer 308 and the second layer 309 together define the outer surfaces 304A, 304B. The third layer 310 is surrounded by the first layer 308 and the second layer 309.

[0041] In some embodiments, the first layer 308 is hydrophilic. Therefore, the first layer 308 allows liquid to pass easily to a third layer 310 located adjacent to the first layer 308. The third layer 310 contains an absorbent material configured to absorb liquid. The absorbent material may include one or more of the following: superabsorbent particles, superabsorbent fibers, cellulose ethyl sulfonate, carboxymethylcellulose, sodium polyacrylate, hydrogel particles, hydrogel nonwoven materials, cellulose foam, hydrogel polyurethane, silicone foam, and polyurethane foam. However, in some embodiments, the addition of additives can change the first layer 308 from hydrophilic to hydrophobic. Once the absorbent pad 202 is saturated with liquid, additives may be added to the outer layer 206.

[0042] In some embodiments, the first layer 308 is tear-resistant. In such embodiments, the absorbable article 301 can be placed in the oral environment without tearing or perforation of the first layer 308 due to contact with the patient's teeth.

[0043] In some embodiments, the second layer 309 is made of a liquid-permeable material. Thus, the second layer 309 can allow 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 does not allow liquid from the third layer 310 to pass through, and thus the liquid can be trapped within the third layer 310. In this way, the second layer 309 can ensure that the flow of liquid within each absorbent pad 302A, 302B is unidirectional.

[0044] Each absorbent pad 302A, 302B includes sealing portions 307A, 307B formed between the first layer 308 and the second layer 309. Specifically, absorbent pad 302A includes sealing portion 307A. Absorbent pad 302A includes sealing portion 307B. The sealing portions 307A, 307B may be formed using any sealing method such as heat sealing, ultrasonic sealing, friction heating, adhesive bonding, or suture. In some embodiments, at least a portion of the sealing portions 307A, 307B may bond an interconnecting member 303 to each of the absorbent pads 302A, 302B.

[0045] The interconnecting member 303 is stretchable. In some embodiments, the interconnecting member 303 is made of an elastomer material. In some embodiments, the elastomer material is rubber. In some embodiments, the interconnecting member 303 is made of a liquid-impermeable material. In some embodiments, the interconnecting member 303 includes at least one of polyurethane, styrene block copolymer, polyester elastomer, and elastomer polyolefin. In some embodiments, the interconnecting member 303 is made of a nonwoven fabric material.

[0046] Figures 4A and 4B show a schematic top view and a schematic perspective view of the absorbent article 401, respectively. The absorbent article 401 is substantially similar to the absorbent article 101 shown in Figure 1A. However, the interconnecting member 103 includes one or more through-openings 411. Each of the one or more through-openings 411 is configured to receive at least one tooth.

[0047] In the embodiments shown in Figures 4A and 4B, the interconnecting member 103 includes only one through-opening 411. In some embodiments, the through-opening 411 may be configured to accept one tooth. In some embodiments, the through-opening 411 may be configured to accept two or more teeth. In the embodiments shown in Figures 4A and 4B, the through-opening 411 is substantially circular 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 according to desired application attributes.

[0048] In some other embodiments, there may be multiple through-openings (such as through-opening 411). In some embodiments, each of the multiple through-openings may be configured to accept one tooth. In some embodiments, the multiple through-openings may be similar in size and shape. In some other embodiments, the multiple through-openings may be different in size and shape. The size and shape of one or more through-openings 411 may vary based on desired application attributes.

[0049] Figures 5A and 5B show a schematic top view and a schematic perspective view of the absorbent article 501, respectively. The absorbent article 501 is substantially similar to the absorbent article 401 shown in Figures 4A and 4B. However, the interconnecting member 103 includes one or more through-openings, 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 two or more teeth. In the illustrated embodiments of Figures 5A and 5B, the slit 511 is substantially oval-shaped 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 according to a desired application attribute. 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 according to a desired application attribute.

[0050] Figure 6A shows a schematic diagram of the patient's mandible 640 and the absorbent article 401 in use. Fluids such as blood, saliva, and / or water may be generated and accumulated within the mandible 640. In some other embodiments, the absorbent article 401 may be placed in the patient's maxilla (not shown). The interconnecting member 103 includes a through-opening 411, as shown in Figure 4A. When in use, the interconnecting member 103 is stretched and positioned over at least one tooth 650 being worked on by a dental clinician. Specifically, the interconnecting member 103 is stretched and positioned over at least one tooth 650 so that the through-opening 411 can surround and secure the at least one tooth 650. In some embodiments, the through-opening 411 may take the shape of at least one tooth 650. In some embodiments, the interconnecting member 103 is stretched and positioned over at least one tooth 650 so that multiple through-openings (not shown) surround and secure the corresponding teeth. Specifically, at least one tooth 650 may protrude through the through-opening 411 to provide the dental clinician with visibility and accessibility to the work area.

[0051] The absorbent pads 102A and 102B may be positioned on either side of at least one tooth 650. This arrangement of the absorbent pads 102A and 102B and the interconnecting member 103 of the absorbent article 401 can isolate at least one tooth 650 and ensure that the liquid is absorbed efficiently from the oral environment without causing discomfort to the patient. The absorbent article 401 can further prevent the liquid from entering the patient's throat. Thereafter, the absorbent article 401 can keep the oral environment dry and provide the dental clinician with visibility and accessibility to the work area.

[0052] In the illustrated embodiment of Figure 6A, an absorbent article 401 is shown. However, in other embodiments, absorbent articles 101 and 301 (shown in Figures 1A and 3, respectively) may be used similarly. When using absorbent articles 101 and 301, the dental clinician may penetrate or puncture the interconnecting members 103 and 303 to form through-openings 411 before stretching the interconnecting members 103 and 303 and positioning them over at least one tooth 650. In some embodiments, the dental clinician may penetrate or puncture the interconnecting members 103 and 303 to form multiple through-openings for receiving corresponding teeth.

[0053] Figure 6B shows a schematic diagram of the patient's mandible 640 and the absorbable article 501 in use. In some embodiments, the absorbable article 501 may be placed in the patient's maxilla (not shown). The interconnecting member 103 includes a slit portion 511, as shown in Figure 5A. When in use, the interconnecting member 103 is stretched and positioned over at least one tooth being worked on by a dental clinician. Specifically, the interconnecting member 103 is stretched and positioned over at least one tooth so that the slit portion 511 can surround and secure at least one tooth. In the illustrated embodiment of Figure 6B, the slit 511 surrounds and secures two teeth 660, 670. In some embodiments, the slit 511 may take the shape of teeth 660, 670. However, in some other embodiments, the slit 511 may surround and secure either one of teeth 660, 670. Specifically, teeth 660 and 670 may protrude through the slit 511 to provide the dental clinician with visibility and accessibility to the working area.

[0054] The absorbent pads 102A and 102B are positioned on both sides of the teeth 660 and 670. This arrangement of the absorbent pads 102A and 102B and the interconnecting member 103 of the absorbent article 501 can isolate the teeth 660 and 670, ensuring that the liquid is efficiently absorbed from the oral environment without causing discomfort to the patient. The absorbent article 501 can further prevent the liquid from entering the patient's throat. Thereafter, the absorbent article 501 can keep the oral environment dry and provide the dental clinician with visibility and accessibility to the work area.

[0055] In the illustrated embodiment of Figure 6B, an absorbent article 501 is shown. However, in other embodiments, absorbent articles 101 and 301 may be used similarly. When using absorbent articles 101 and 301, the dental clinician may penetrate or puncture the interconnecting members 103 and 303 to form a slit 511 before stretching the interconnecting members 103 and 303 and placing them on the teeth 660 and 670.

[0056] Figures 7A to 7G show schematic diagrams of various absorbent pads having different shapes. Specifically, Figures 7A to 7G show the respective absorbent pads 602A, 602B, 602C, 602D, 602E, 602F, and 602G. Absorbent pad 602A has a substantially rectangular parallelepiped shape. Absorbent pad 602B has a pyramidal shape. Absorbent pad 602C has a prism shape. Absorbent pad 602D has a spherical shape. Absorbent pad 602E has a substantially L-shape. Absorbent pad 602F has a three-dimensional shape. Absorbent pad 602G has a triangular pyramidal shape. As is evident from Figures 7A to 7G, the absorbent pads 602A, 602B, 602C, 602D, 602E, 602F, and 602G may be designed in any shape to fit different parts of the patient's oral cavity without causing discomfort. In some embodiments, the absorbent pads 602A, 602B, 602C, 602D, 602E, 602F, and 602G may be filled with absorbent material by an injection molding process.

[0057] Similarly, the absorbent pads 602A, 602B, 602C, 602D, 602E, 602F, and 602G may have any size depending on the size of the patient's mouth. For example, if the patient is a child, the size of the absorbent pads 602A, 602B, 602C, 602D, 602E, 602F, and 602G may be relatively small.

[0058] Figures 8A and 8B show a schematic top view and schematic perspective view of the absorbent article 701, respectively. The absorbent article 701 is substantially similar to the absorbent article 101 shown in Figures 1A and 1B. The absorbent article 701 includes at least two absorbent pads 702A, 702B spaced apart from each other. However, as shown in Figures 8A and 8B, each absorbent pad 702A, 702B is arc-shaped such that the first absorbent pad 702A of the at least two absorbent pads 702A, 702B forms an inner arc 713, and the 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 the shape of the patient's mandible 640 (shown in Figures 6A and 6B). Therefore, the absorbent article 701 can easily fit into the patient's mouth without causing discomfort to the patient.

[0059] Each absorbent pad 702A, 702B further includes outer surfaces 704A, 704B. The interconnecting member 703 joins the outer surfaces 704A, 704B of at least two absorbent pads 702A, 702B. In some embodiments, the interconnecting member 703 includes one or more through openings 711A, 711B, 711C, 711D, 711E (collectively, one or more through openings 711). Each of the one or more through openings 711 is configured to receive at least one tooth. In the embodiments illustrated in Figures 8A and 8B, the interconnecting member 703 includes five through openings 711. However, in some other embodiments, the interconnecting member 703 may include more than five through openings 711. In some other embodiments, the interconnecting member 703 may include fewer than five through openings 711. In some other embodiments, the interconnecting member 703 may include one through opening 711.

[0060] The first absorbent pad 702A and the second absorbent pad 702B of the absorbent article 701 may cover both sides of at least one tooth while exposing only that tooth to the dental clinician. This allows the absorbent article 701 to keep the oral environment dry and to provide the dental clinician with visibility and accessibility to the work area.

[0061] Figure 8C shows a schematic top view of the 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 expandable and contractible. In some embodiments, the inner member 816 is made of a liquid-impermeable material. In some embodiments, the interconnecting member 703 and the inner member 816 of the absorbent article 701 are made of similar materials. The inner member 816 may be placed on the patient's tongue. The inner member 816 may cover the patient's tongue and protect the patient from sharp instruments used by the dental clinician. The inner member 816 may further restrict the flow of liquid to the patient's tongue. The inner member 816 may further help to keep the patient's tongue away from at least one tooth.

[0062] Figures 9A, 9B, and 9C show absorbent pads 902A, 902B, and 902C, respectively. Absorbent pads 902A, 902B, and 902C are substantially the same as absorbent pad 102A in Figure 1A. Absorbent pads 902A, 902B, and 902C include outer surfaces 914A, 914B, and 914C, respectively. However, each absorbent pad 902A, 902B, and 902C further includes wire meshes 917A, 917B, and 917C disposed on the outer surfaces 914A, 914B, and 914C. Specifically, absorbent pad 902A includes wire mesh 917A disposed on outer surface 914A. Absorbent pad 902B includes wire mesh 917B disposed on outer surface 914B. Furthermore, the absorbent pad 902C includes a wire mesh 917C disposed on the outer surface 914C. In some embodiments, each of the wire meshes 917A, 917B, and 917C may include a ductile wire. The wire meshes 917A, 917B, and 917C can help conform each absorbent pad 902A, 902B, and 902C to a desired shape that fits the patient's oral cavity. In other words, the wire meshes 917A, 917B, and 917C can deform and change the shape of each absorbent pad 902A, 902B, and 902C to fit different inner sizes and shapes of the oral cavity. Absorbent pads 902A, 902B, and 902C including the wire meshes 917A, 917B, and 917C can provide good coverage to areas where fluids such as blood, saliva, and / or water are generated and accumulate, and thus can provide efficient absorption of fluids from the oral environment. In some other embodiments, the wire meshes 917A, 917B, and 917C may be embedded within their respective absorbent pads 902A, 902B, and 902C. For example, the wire meshes 917A, 917B, and 917C may be embedded within a third layer 310 (shown in Figure 3). In such embodiments, the wire meshes 917A, 917B, and 917C can hold the absorbent material in place. In some other embodiments, the wire meshes 917A, 917B, and 917C may be embedded within a first layer 308 (shown in Figure 3) and / or a second layer 309 (shown in Figure 3).

[0063] Figure 10 shows a schematic diagram of the absorbent article 1001. The absorbent article 1001 is substantially similar to the absorbent article 701 in Figure 8A. However, at least one of the two absorbent pads 702A, 702B includes a tube 1013 that is 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 generate negative pressure inside the tube 1013. In some embodiments, the tube 1013 is flexible and can be easily bent to conform to other shapes. The suction source 1012 can provide active suction to remove excess liquid from at least one of the two absorbent pads 702A, 702B once that pad is saturated. In some embodiments, the suction source 1012 may be located away from the absorbent article 701.

[0064] Figures 11A to 11E show an absorbent article 931 according to another embodiment of the present disclosure. Specifically, Figure 11A shows a schematic perspective view of the absorbent article 931, Figure 11B shows a schematic cross-sectional view of the absorbent article 931 along line 1-1 in Figure 11A, Figure 11C shows a schematic front view of the absorbent article 931, Figure 11D shows a schematic rear view of the absorbent article 931, and Figure 11E shows a schematic top view of the absorbent article 931.

[0065] Referring to Figures 11A to 11E, the absorbent article 931 includes at least two absorbent pads 932A and 932B that are spaced apart from each other. Each absorbent pad 932A and 932B includes outer surfaces 934A and 934B. Specifically, absorbent pad 932A includes outer surface 934A, and absorbent pad 932B includes outer surface 934B.

[0066] Each absorbent pad 932A, 932B contains absorbent material 935A, 935B (shown in Figure 11B). In other words, absorbent material 935A, 935B is placed within each absorbent pad 932A, 932B. Specifically, absorbent pad 932A contains absorbent material 935A, and absorbent pad 932B contains absorbent material 935B. Absorbent material 935A, 935B is configured to absorb liquid. In some embodiments, the liquid includes at least one of saliva, water, and blood.

[0067] In some embodiments, the absorbent materials 935A and 935B are made from one or more superabsorbent particles, superabsorbent fibers, cellulose ethyl sulfonate, carboxymethylcellulose, sodium polyacrylate, hydrogel particles, hydrogel-based nonwoven fabrics, cellulose foams, hydrogel polyurethanes, silicone foams, and polyurethane foams. Absorbent material 935A may be the same as or different from absorbent material 935B.

[0068] Furthermore, the absorbent materials 935A and 935B may have a suitable absorption rate depending on the desired application attributes. In some embodiments, liquid absorption does not necessarily increase the size or volume of the absorbent pads 932A and 932B. However, in some other embodiments, liquid absorption may increase the size or volume of the absorbent pads 932A and 932B.

[0069] The absorbent article 931 further includes an interconnecting member 933. The interconnecting member 933 joins the outer surfaces 934A and 934B of at least two absorbent pads 932A and 932B. Furthermore, the interconnecting member 933 is expandable and contractible.

[0070] In some embodiments, each absorbent pad 932A, 932B further comprises films 936A, 936B. Specifically, in some embodiments, absorbent pad 932A comprises film 936A, and absorbent pad 932B comprises film 936B. Films 936A, 936B are made of a liquid-permeable material. Films 936A, 936B may allow liquids (e.g., saliva, water, and blood) to pass through them.

[0071] In some embodiments, films 936A and 936B comprise at least one of polyurethane, styrene block copolymer, polyester elastomer, elastomer polyolefin, and nonwoven fabric material. In some embodiments, films 936A and 936B are tear-resistant. In some embodiments, films 936A and 936B are hydrophilic. Film 936A may be the same as or different from film 936B.

[0072] As shown in Figures 11A and 11B, in some embodiments, films 936A and 936B are folded over themselves to form three or more folded layers 937A and 937B. Specifically, in some embodiments, film 936A is folded over itself to form three or more folded layers 937A, and film 936B is folded over itself to form three or more folded layers 937B. Films 936A and 936B may be folded over themselves to form three, more than three, more than four, more than five, more than six, more than seven, or more than eight folded layers 937A and 937B.

[0073] Films 936A and 936B may form at least partially the outer surfaces 934A and 934B of each absorbent pad 932A and 932B. Specifically, film 936A may form at least partially the outer surface 934A of absorbent pad 932A, and film 936B may form at least partially the outer surface 934B of absorbent pad 932B.

[0074] In the embodiment shown in Figure 11B, the films 936A and 936B further form hollow cores 938A and 938B. Specifically, in the embodiment shown in Figure 11B, film 936A forms the hollow core 938A, and film 936B forms the hollow core 938B. Furthermore, in the embodiment shown in Figure 11B, absorbent materials 935A and 935B are arranged within the hollow cores 938A and 938B. In some embodiments, the absorbent materials 935A and 935B arranged within the hollow cores 938A and 938B may be in powder form.

[0075] Furthermore, in the embodiment shown in Figure 11B, at least one absorbent pad 932B further includes a spacer material 940 disposed within the hollow core 938B of at least one absorbent pad 932B. In some embodiments, the spacer material 940 is configured to increase the radial stiffness of at least one absorbent pad 932B. The spacer material 940 may have any preferred shape and dimensions to increase the radial stiffness of at least one absorbent pad 932B. The spacer material 940 may occupy, for example, more than 30%, more than 40%, more than 50%, more than 60%, or more than 70% of the volume of the hollow core 938B. In some examples, the spacer material 940 may include a stiff cloth.

[0076] In some embodiments, each absorbent pad 932A, 932B may include a spacer material 940 placed within the hollow core 938A, 938B, the spacer material 940 may increase the radial stiffness of each absorbent pad 932A, 932B. However, it should be noted that the spacer material 940 is optional and may be omitted.

[0077] Furthermore, the films 936A and 936B may completely surround the absorbent materials 935A and 935B by any preferred means (for example, by a sealing member) so that the absorbent materials 935A and 935B are not exposed and are contained within each absorbent pad 932A and 932B. In some examples, the films 936A and 936B may further completely surround the spacer material 940.

[0078] As shown in Figures 11A and 11C to 11E, in some embodiments, the films 936A, 936B of each absorbent pad 932A, 932B include a first tapered portion 942A, 942B and a second tapered portion 944A, 944B opposite to the first tapered portion 942A, 942B, such that the films 936A, 936B completely surround the absorbent material 935A, 935B (shown in Figure 11B). The first tapered portion 942A, 942B and the second tapered portion 944A, 944B may be formed by pinching and compressing the opposite portion of the film 936A, 936B.

[0079] In some embodiments, the film 936A of the absorbent pad 932A includes a first tapered portion 942A and a second tapered portion 944A opposite to the first tapered portion 942A, such that the film 936A completely surrounds the absorbent material 935A (shown in Figure 11B). Furthermore, in some embodiments, the film 936B of the absorbent pad 932B includes a first tapered portion 942B and a second tapered portion 944B opposite to the first tapered portion 942B, such that the film 936B completely surrounds the absorbent material 935B (shown in Figure 11B). In some cases, each of the first tapered portions 942A, 942B and the second tapered portions 944A, 944B may have a relatively flat portion.

[0080] In some embodiments, each absorbent pad 932A, 932B further includes at least first sealing portions 945A, 945B (shown by dashed lines in Figures 11A and 11C to 11E) configured to seal the films 936A, 936B in the first tapered portions 942A, 942B, and at least second sealing portions 947A, 947B (shown by dashed lines in Figures 11A and 11C to 11E) configured to seal the films 936A, 936B in the second tapered portions 944A, 944B. Specifically, in the embodiments shown in Figures 11A and 11C to 11E, the absorbent pad 932A includes a first sealing portion 945A configured to seal the film 936A at the first tapered portion 942A, and a second sealing portion 947A configured to seal the film 936A at the second tapered portion 944A. Furthermore, in the embodiments shown in Figures 11A and 11C to 11E, the absorbent pad 932B includes a first sealing portion 945B configured to seal the film 936B at the first tapered portion 942B, and a second sealing portion 947B configured to seal the film 936B at the second tapered portion 944B. The first sealing portions 945A, 945B and the second sealing portions 947A, 947B can prevent the absorbent material 935A, 935B from detaching from the hollow core 938A, 938B of the film 936A, 936B.

[0081] The first seal portions 945A, 945B and the second seal portions 947A, 947B may be formed by any preferred sealing method such as heat sealing, ultrasonic sealing, friction heating, adhesive bonding, or suturing. For example, the first seal portions 945A, 945B and the second seal portions 947A, 947B may be ultrasonically welded. In some examples, the first seal portions 945A, 945B and the second seal portions 947A, 947B may partially extend onto the interconnecting member 933.

[0082] Furthermore, in some embodiments, the interconnecting member 933 and the films 936A, 936B of each absorbent pad 932A, 932B form a single integrated film member. For example, film 936A may be a first part of the single integrated film member, the interconnecting member 933 may be a second part of the single integrated film member, and film 936B may be a third part of the single integrated film member. In other words, in some embodiments, film 936A and film 936B may be integral. Furthermore, in such embodiments, the absorbent article 931 may be formed by folding a single integrated film member including films 936A, 936B at both ends to form at least two absorbent pads 932A, 932B, thereby the single integrated film member further forms an interconnecting member 933 between at least two absorbent pads 932A, 932B.

[0083] Figure 12 shows a schematic cross-sectional side view of an absorbent article 951 according to another embodiment of the present disclosure. The absorbent article 951 is similar to the absorbent article 931 in Figures 11A to 11E, and similar elements are indicated by the same reference numerals. However, the absorbent article 951 has a different arrangement of absorbent materials 935A, 935B compared to the absorbent article 931 in Figures 11A to 11E.

[0084] In the illustrated embodiment of Figure 12, the absorbent materials 935A and 935B are positioned between at least two adjacent folded layers 937A and 937B from three or more folded layers 937A and 937B. Specifically, in the illustrated embodiment of Figure 12, the absorbent material 935A is positioned between at least two adjacent folded layers 937A from three or more folded layers 937A, and the absorbent material 935B is positioned between at least two adjacent folded layers 937B from three or more folded layers 937B. In some embodiments, the absorbent materials 935A and 935B positioned between at least two adjacent folded layers 937A and 937B may be in fibrous form.

[0085] In such embodiments, one or more sealing portions may be provided (in addition to the first sealing portions 945A, 945B and the second sealing portions 947A, 947B in Figures 11A and 11C to 11E) to ensure that the absorbent materials 935A, 935B are completely surrounded by the films 936A, 936B. Furthermore, in such embodiments, the films 936A, 936B may or may not form a hollow core (similar to the hollow cores 938A, 938B shown in Figure 11B), depending on the type and stiffness of the overlap of the films 936A, 936B. In embodiments where a hollow core is formed, the absorbent materials 935A, 935B may be further placed within the hollow core. Furthermore, a spacer material (similar to the spacer material 940 shown in Figure 11B) may optionally be placed within the hollow core.

[0086] Figures 13A and 13B show an absorbent article 961 according to another embodiment of the present disclosure. Specifically, Figure 13A shows a schematic cross-sectional side view of the absorbent article 961, and Figure 13B shows a schematic top view of the absorbent article 961. The absorbent article 961 is similar to the absorbent article 951 of Figure 12, and similar elements are indicated by the same reference numerals. However, the absorbent article 961 has a different configuration of films 936A and 936B compared to the absorbent article 951 of Figure 12.

[0087] Specifically, in the embodiment shown in Figure 13A, the films 936A and 936B are folded over themselves in a fan-fold configuration (also called an accordion or z-fold configuration) to form three or more folded layers 937A and 937B. Furthermore, in the embodiment shown in Figure 13A, the absorbent materials 935A and 935B are positioned between at least two adjacent folded layers 937A and 937B from the three or more folded layers 937B and 937B.

[0088] As shown in Figure 13B, in some embodiments, each absorbent pad 932A, 932B may further include a third seal portion 948A, 948B extending between at least the first seal portions 945A, 945B and the second seal portions 947A, 947B, and a fourth seal portion 949A, 949B extending between at least the first seal portions 945A, 945B and the second seal portions 947A, 947B on the opposite side of the third seal portions 948A, 948B. The third seal portions 948A, 948B and the fourth seal portions 949A, 949B can ensure that the films 936A, 936B completely surround the absorbent material 935A, 935B in an accordion configuration.

[0089] Figure 14A shows a schematic cross-sectional side view of an absorbent article 971 according to another embodiment of the present disclosure. The absorbent article 971 is substantially similar to the absorbent article 931 of Figures 11A to 11E, and similar elements are indicated by similar reference numerals. However, the absorbent article 971 has a different configuration of films 936A, 936B compared to the absorbent article 931 of Figures 11A to 11E.

[0090] Specifically, in the embodiment shown in Figure 14A, the films 936A and 936B are folded over themselves in a spiral configuration to form three or more folded layers 937A and 937B. The films 936A and 936B may be folded over themselves in a spiral configuration via any suitable mechanical rotating device. The three or more folded layers 937A and 937B may be concentric or non-concentric in the spiral configuration. Furthermore, in the embodiment shown in Figure 13A, the films 936A and 936B further form hollow cores 938A and 938B, and the absorbent material 935A and 935B is placed within the hollow cores 938A and 938B.
