Patent Description:
Human survival rely greatly on fluids, especially air and water. For human bodies, fluids sometimes are necessities, while sometimes are burdens. Fluids are needed by human bodies in some situations such as urinalysis, breast augmentation, skin care, wound care, cooling or keeping warm, staying hydrated, breastfeeding, etc. Fluids are a burden to human in some situations such as treating body fluids (breast milk, urine, semen, blood), etc..

Although there have been several solutions for the need or the burden between fluids and human bodies, there are still many deficiencies. For example, as for satisfying human's needs, such as for flat-chested females, bra pads would easily shift, NuBras would lose adhesiveness after repeatedly used, and surgery implanting fluids (saline implants, silicone implants) is painful and expensive. As for relieving burden, for example, babies and bedridden females would face the pain of urinary catheterization and the risk of infection when collecting urine, people with urinary incontinence would feel discomfort when wearing diapers, or face difficulties using each kind of urine collection bag which causes the leakage of urine. <CIT> discloses a fluid-carrying application according to the preamble of claim <NUM>.

In view of the above problems, the present invention provides a fluid-carrying application to temporarily keep fluids on body surfaces, which is easy to adhere to human bodies and does not easily peel off. The present invention is capable of collecting various fluids such as water, air, skin care products, liquid medicine, milk, urine, semen, or blood without leakage, meanwhile meeting human's demands for fluids and releasing the burden of fluids for human bodies. The present invention provides a simple structure, which is easy to use and low-cost. The application of the present invention may be widely used and can process the relationship between human bodies and fluids properly.

To achieve the above objectives, the present invention provides a fluid-carrying application, according to claim <NUM>. Different embodiments are disclosed in claims <NUM>-<NUM>.

Specific implementations of the present invention are described below with reference to the accompanying drawings, wherein the same or similar components are denoted by the same reference numerals.

<FIG> is an embodiment of the present invention. The fluid-carrying application <NUM> comprises a first sheet <NUM> with at least a first drainage port <NUM>, with the first sheet <NUM> having a first surface S1 and a second surface S2, and a second sheet <NUM> having a third surface S3 and a fourth surface S4. A part of the third surface S3 and a part of the second surface S2 of the first sheet <NUM> are connected (welded or adhered) to at least a band-shaped region <NUM>, thereby forming a first chamber R1 having at least an opening which may store fluids. The inside of the first chamber R1 can communicate with the outside through the first drainage port <NUM>. The edge of the first sheet <NUM> and the edge of the second sheet <NUM> may, but not limited to, align with each other. An adhesive layer <NUM> is set up at the fourth surface S4 of the second sheet <NUM> for adhesion to a user, and to attach the fluid-carrying application <NUM> to the body surface. A release layer <NUM>, which covers at least a part of the adhesive layer <NUM>, and prevents the adhesive layer <NUM> from losing the adhesiveness due to staining before use. The release layer <NUM> may be, for example, a release paper.

The fluid-carrying application <NUM> may be made of, for example, but not limited to, natural latex, synthetic latex, rubber, silicone, polyisoprene (PI), polyurethane (PU), polyethylene (PE), polyvinyl chloride (PVC), a polymer material, a biomaterial or a synthetic DNA material. The material constituting the adhesive layer <NUM> may include, for example, a pressure-sensitive adhesive, which is used for the adhesion of the second sheet <NUM> on the user's skin through the adhesive layer <NUM>. The second sheet <NUM> may also be made of a viscous material. The second surface S2 of the first sheet <NUM> and the third surface S3 of the second sheet <NUM> are interconnected. The interconnection may be achieved by adhesion using such as, but not limited to, a solvent, an adhesive, a tape, or a glue film, or may be welded and connected by, for example, but not limited to, electric heating, ultrasonic, or high-frequency welding.

The first sheet <NUM> and the second sheet <NUM> may be soft sheets in natural state, which may be preferably made of an elastic material, yet an inelastic material may also be used. The thickness of the first sheet <NUM> and the second sheet <NUM> is preferably no more than <NUM>. The first sheet <NUM> and the second sheet <NUM> may be fabricated as a flat or arc-surface film, and the edge may be in the shape of, but not limited to, a circle, an ellipse, a rounded regular polygon, or in any shape. Preferably, the first sheet <NUM> is a water-proof sheet, such as a thermoplastic polyurethane (TPU) film. The second sheet <NUM> which is configured for adhesion to the user's skin requires better air permeability and may be made of a microporous film, such as, but not limited to, a highly air/water-permeable polyurethane (PU) film. The thickness of the second sheet <NUM> is preferably less than <NUM>, more preferably less than <NUM>, and most preferably less than <NUM>. The air permeability of the second sheet <NUM> is preferably with a moisture vapor transmission rate (MVTR) greater than or equal to <NUM>/(m<NUM>·<NUM>), and the water permeability after gumming thereof is preferably greater than or equal to <NUM>/(m<NUM>·<NUM>). To improve comfort and the compatibility with the skin, any material may be attached to the first surface S1 of the first sheet <NUM>, such as woven materials, nonwoven materials or films. For ease of understanding the structures of the sheets, most of the following drawings are shown in sectional views and in exemplary forms with the chamber full of fluids.

<FIG> are another embodiment of the present invention. Between the first sheet <NUM> and the second sheet <NUM> of the fluid-carrying application <NUM> is provided with a third sheet <NUM>, thereby forming a second chamber R2 between the third sheet <NUM> and the second sheet <NUM>. The edge of the third sheet <NUM> may be welded/adhered in between the first sheet <NUM> and the second sheet <NUM> at the same time (as shown in <FIG>), or welded/adhered to the first sheet <NUM> (as shown in <FIG>), or welded/adhered to the second sheet <NUM> (as shown in <FIG>). The first chamber R1 and the second chamber R2 may be injected with the same or different fluids, respectively.

<FIG> is another embodiment of the present invention, which may be used for ice packs/warm compresses. The first drainage port <NUM> at the first sheet <NUM> further comprises a drainage portion, which is connected to the first drainage port <NUM>, and enables the inside of the first chamber R1 to connect with outside through the first drainage port <NUM> and the drainage portion. The first drainage port <NUM> may also be formed by an open portion of the connecting part, which was formed by overlapping and connecting the edges of the two first sheet <NUM>. In the present embodiment, the first sheet <NUM> and the second sheet <NUM> are thermoplastic films. The edges of the first sheet <NUM> and the second sheet <NUM> are heat seal processed to form a band-shaped region <NUM> in a continuously enclosed manner. The drainage portion is a drainage tube <NUM> being set up correspondingly to the first drainage port <NUM>. One end of the drainage tube <NUM> is connected to the first sheet <NUM>, and the first chamber R1 is in communication with outside through the first drainage port <NUM>. The drainage tube <NUM> has an inner cross sectional area which is generally the same as or greater than the first drainage port <NUM>, and the configuration may be in a manner of connecting the cross section of the tube wall of one end of the drainage tube <NUM> with the first surface S1 or the second surface S2 of the first sheet <NUM>. Alternatively, as shown in <FIG>, one end of the drainage tube <NUM> may be provided with a brim portion <NUM>, which is generally perpendicular to an axial direction of the drainage tube <NUM> and surrounds the periphery of the drainage tube <NUM> (exemplarily, the two elements are herein connected integrally). The brim portion <NUM> is connected to the first surface S1 of the first sheet <NUM>, thereby increasing the fitting tightness and the reliability of connection between the drainage tube <NUM> and the first sheet <NUM>. The drainage tube <NUM> may be provided with a closed end, which is formed integrally with other parts of the drainage tube <NUM>, such as a test tube. Alternatively, the drainage tube <NUM> may further comprise a cap <NUM> for the drainage tube <NUM> to be opened or closed. In the present embodiment, the drainage tube <NUM> extends from the first drainage port <NUM> to the direction opposite of the first chamber R1, and the cap <NUM> and the drainage tube <NUM> are threadedly locked with each other. When in use, the fluid-carrying application <NUM> is attached to a user's skin through the adhesive layer <NUM>, cold/hot water is injected into the first chamber R1, and the drainage tube <NUM> is closed with the cap <NUM>, which may help the user with icing, warm compression, physiotherapy, or keeping warm in cold weather. The drainage tube <NUM> may also be used to drain and exchange the water when the water temperature is similar to the body temperature. It may be understood by those of ordinary skill in the art that in this embodiment, the design may be simplified by replacing the threads with a flange provided on one of the cap <NUM> and the drainage tube <NUM> and a concave flange provided on the other, so that the two may be fixed with each other.

<FIG> is another embodiment of the present invention, which may achieve the effect of increasing a female's breast size visually after wearing clothes. The brim portion <NUM> of the drainage tube <NUM> is connected to the second surface S2 of the first sheet <NUM>. The drainage tube <NUM> extends from the first drainage port <NUM> to the direction of the first chamber R1 for fluid injection. After the injection of water, upon closing the drainage tube <NUM> with the cap <NUM>, the fluid in the first chamber R1 would be drained due to pressure or gravity. As a result, the drainage tube <NUM> may further comprise a non-return structure to prevent the fluid from flowing from the inside of the first chamber R1 to outside through the drainage tube <NUM>. The first chamber R1 is formed by connecting the first sheet <NUM> and the second sheet <NUM> with the continuously enclosed band-shaped region <NUM>. Especially the first chamber R1 which is made of soft sheets, would expand like a pillow from the periphery to the center when being full of fluids, and the pressure of the fluids would make the edges of the second sheet <NUM> peel off easily from the body surface. To solve the above problems, the edge of the second sheet <NUM> may be larger than the outer edge of the band-shaped region <NUM> or the edge of the first sheet <NUM>, thereby forming a distance between the outer edge of the band-shaped region <NUM> and the edge of the second sheet <NUM>, wherein the widest part of the distance is preferably greater than <NUM>, more preferably greater than <NUM>, most preferably greater than <NUM>, so as to improve the fitting of the periphery of the fluid-carrying application <NUM>. Such as a tent that is secured to the ground with ropes and tent stakes, the radially protruded second sheet <NUM> (such as a rope) may better attach a surface of the first chamber R1 that is adjacent to the second sheet <NUM> on the body surface through the adhesive layer <NUM> (such as a tent stake). Furthermore, with regard to the second sheet <NUM>, setting the inner edge of the band-shaped region <NUM> as the reference point, the effect of bilateral fix at the inner side and the outer side of the second sheet <NUM> is achieved by the adhesive layer <NUM>, and effectively prevents the second sheet <NUM> from peeling off from the body surface due to excessive tensile force or hydraulic pressure applied on the first sheet <NUM>. In addition, since the second sheet <NUM> is larger than the outer edge of the band-shaped region <NUM> (that is, there is a distance between the edge of the second sheet <NUM> and the outer edge of the band-shaped region <NUM>), the total thickness gradually increases from the edge to the center. Comparing to the configuration shown in <FIG> where the thicker (two layers) edge is formed by the first sheet <NUM> and the second sheet <NUM> aligning with each other, and the thicker edge is easily rolled up due to friction, the thinner edge may better prevent the periphery of the fluid-carrying application <NUM> from peeling off due to friction. The present invention may further comprise a structure support unit <NUM>, which extends along the edge of the first sheet <NUM> or the second sheet <NUM>, functioning as a frame being set up at the first sheet <NUM> or the second sheet <NUM>, in order to maintain the shape of the edge before adhesion and prevent the formation of folds. After adhesion, the user may remove the structure support unit <NUM>. In the present embodiment, the second sheet <NUM> for adhesion to a breast is a flat film, while the first sheet <NUM> is preferably made of an arc-surface film, thereby increasing the volume of the first chamber R1 and can increase the breast size visually. Additionally, a fourth sheet <NUM> may be set up at least a part of the adhesive layer <NUM> for sweat absorption. The fourth sheet <NUM> is an absorbent sheet comprising fibers, pores, or water absorbing polymeric materials, such as but not limited to tissue papers, cottons, gauzes, non-woven fabrics, sponges, or artificial skin. The edge of the fourth sheet <NUM> does not extend beyond the inner edge of the band-shaped region <NUM>. Apart from increasing the size of breast shape visually, one may flatter figures of other parts using the same methods, such as but not limited to the plantar arc of a flat foot.

<FIG> show the steps of utilizing the present invention to increase the size of a breast shape visually for a female when wearing clothes. The fluid-carrying application <NUM> comprises a fifth sheet <NUM>. A part of the fifth sheet <NUM> is connected to the second surface S2 of the first sheet <NUM> and is provided with a liftable part <NUM>. The liftable part <NUM> is larger than the first drainage port <NUM> and is able to fully cover the first drainage port <NUM> from the inner side of the first chamber R1. Therefore, the liftable part <NUM> may only be lifted toward the inside of the first chamber R1 and achieves the effect of a non-return valve, and prevent the fluid from flowing from the inside of the first chamber R1 to outside through the first drainage port <NUM> (if a part of the fifth sheet <NUM> is connected to the first surface S1 of the first sheet <NUM>, there will be a reverse effect). In step <NUM>, as shown in <FIG>, the release layer <NUM> is separated and peeled off to expose the adhesive layer <NUM> on the second sheet <NUM>. In step <NUM>, as shown in <FIG>, the second sheet <NUM> is adhered to the breast skin with the adhesive layer <NUM> facing towards the breast. In step <NUM> (not necessary), as shown in <FIG>, the structure support unit <NUM> is removed. In step <NUM>, as shown in <FIG>, an appropriate amount of water is injected through the first drainage port <NUM>, and the hydraulic pressure inside the first chamber R1 would push the liftable part <NUM> towards the first drainage port <NUM> and therefore clog the first drainage port <NUM>. The gradually expanding first chamber R1 causes the second sheet <NUM> to apply pressure on the soft tissue of the covered part of the breast in the direction towards the pectoralis major muscle, causing the breast to appear in a recessed state, while the first sheet <NUM> combines with the uncovered skin of the breast to form an enlarged breast shape. In step <NUM>, as shown in <FIG>, the first drainage port <NUM> is covered with the cap <NUM> provided with a reusable adhesive to prevent a small amount of fluid from seeping. The water inside the first chamber R1 may combine with the user's breast through the above steps and form a natural body shape. It is also convenient for females to further adjust the volume of the breast by adjusting the amount of injected water. Since the specific gravity of water is approximately equal to the specific gravity of a human body, the characteristics of fluids may better provide the natural bounce and jiggle, and the sense of touch of the breast.

An embodiment of the present invention is shown in <FIG>. A piece of a part of the first sheet <NUM> extends outwards and forms an extending portion <NUM>. The extending portion <NUM> is reversely folded and the edge of which is connected to the first sheet <NUM>, forming into a belt. An embodiment of the present invention is shown in <FIG>. The first sheet <NUM> or the second sheet <NUM> is provided with undulating edges, enabling the fluid-carrying application <NUM> to better attach on a non-planar surface. The second sheet <NUM> with the undulating edge may also serve as a claw that provides a grip strength, and can better resist the external pulling force when the chamber is full of fluids. A fastener <NUM> may be further set up at the edge of the first sheet <NUM> or the second sheet <NUM> to connect two adjacent fluid-carrying applications <NUM> in a permanent or removable way. A fastener <NUM> may be, but is not limited to, a buckle, a button, a rivet/stud, a hasp, a zipper, a tape, a Velcro, or a binding band/rope. In the present embodiment, the fastener <NUM> is a C-shaped/U-shaped buckle. The two ends of the buckle pass through two aforementioned belts from the extending portion <NUM> of the first sheet <NUM> which faces towards each other, respectively, thereby shortening the distance between the two breasts, centering the breasts and boosting the cleavage visually.

<FIG> show another embodiment of the present invention with two first drainage ports <NUM>. The second sheet <NUM> is exemplarily shown with the same piece, where the petaloid edge achieves the same effect as the undulating edge shown in <FIG>, enabling the second sheet <NUM> to better attach on a non-planar surface. A non-return structure, a C-shaped/U-shaped first liftable part <NUM> formed by die-cutting the first sheet <NUM>, forms a part of the first drainage port 12A. A sixth sheet <NUM> is further set up at the first drainage port 12A. The edge of the sixth sheet <NUM> is connected in an enclosed manner to the first surface S1 of the first sheet <NUM> in a form of surrounding the first liftable part <NUM>, and is provided with an opening with the opening smaller than the first liftable part <NUM> and can be fully covered by the first liftable part <NUM> from the inner side of the first chamber R1. Therefore, the first liftable part <NUM> can only be lifted towards the inside of the first chamber R1 and performs the effect of a non-return valve, which prevents the fluids injected by the user from flowing from the inside of the first chamber R1 to outside through the first drainage port 12A (if the edge of the sixth sheet <NUM> is connected to the second surface S2 of the first sheet <NUM>, there will be a reverse effect). As shown in <FIG>, an open portion is formed where the second surface S2 of the first sheet <NUM> and the third surface S3 adjacent to the edge of the second sheet <NUM> are not welded or adhered with each other, and the open portion serves as another first drainage port 12B. When a non-return structure is set up at the first drainage port 12B (not shown in the figure), the first liftable part <NUM> may be formed at the edge of the first sheet <NUM> adjacent to the first drainage port 12B, while the edge of the sixth sheet <NUM> is connected to the first sheet <NUM> and the second sheet <NUM> at the same time in an enclosed manner in a form of surrounding the first liftable part <NUM>. The first drainage port 12B may further comprise a drainage portion. In the present embodiment, the drainage portion is a drainage tube <NUM> sandwiched between the first sheet <NUM> and the second sheet <NUM>. An extending tube <NUM> may be further connected to the drainage tube <NUM> for draining. The fluid in the first chamber R1 may be drained through the first drainage port 12B, the drainage tube <NUM> and the extending tube <NUM> to the user's mouth. Thus the present invention may be provided as a water bottle adhered to the user's body for outdoor activities' use, such as long-distance running, biking, long-distance swimming or diving. Users are therefore able to drink water or consume liquid diet during the activities. Alternatively, the first chamber R1 may be formed as a flowing space with one end for injecting while the other for draining. When the present invention is used for ice packs/warm compresses, water with the same temperature may be continuously injected to keep the first chamber R1 at a constant temperature. Apart from gumming on the second sheet <NUM> during manufacturing, the materials composing the adhesive layer <NUM> may further include, for example but not limited to, a double-sided tape. One surface of the double-sided tape may be adhered to the second sheet <NUM> while the other surface adheres to a user, thus the first chamber R1 formed by the connection of the first sheet <NUM> and the second sheet <NUM> may be repeatedly used simply by changing the double-sided tape. <FIG> is a front view. The drainage tube <NUM> is formed by the connection of two side edges of two seventh sheets <NUM>. The first drainage port 12B surrounds the drainage tube <NUM>. A part of the seventh sheet <NUM> that is adjacent to the first drainage port 12B connects with the second surface S2 of the first sheet <NUM> and the third surface S3 of the second sheet <NUM> respectively in an enclosed manner (as shown in <FIG>), causing the drainage tube <NUM> to be flat in a natural state. The drainage tube <NUM> made of thin films with the thickness less than <NUM> may achieve an non-return effect, preventing the fluid in the first chamber R1 from draining. One of the surfaces of the drainage tube <NUM> that face each other is provided with an isolation material <NUM> (not shown in the figures), and therefore prevents the blockage of fluid flow, which results from the melting and bonding of the inner surfaces (apart from the two side edges) of the seventh sheet <NUM> due to the heat during the manufacturing. The isolation material <NUM> is sandwiched, coated or printed before the drainage tube <NUM> is formed by the connection of the two sheets. An isolation material <NUM> is set up at a part of the seventh sheet <NUM> that is adjacent to the second sheet <NUM> (as shown in <FIG>). In the present embodiment, the first sheet <NUM> may further comprise an extending portion <NUM>, which replaces the seventh sheet <NUM> that connects to the first sheet <NUM> (that is, the first sheet <NUM> and the seventh sheet <NUM> are formed integrally), thus forming a drainage tube <NUM>. <FIG> is a front view. The drainage portion is a drainage bag <NUM> being set up correspondingly to the first drainage port 12B. Similar with the drainage tube <NUM> in <FIG>, the drainage bag <NUM> is formed by connecting the two side edges of the two seventh sheets <NUM> as well as the bottom edge. The volume of the drainage bag <NUM> may be increased by widening and lengthening the seventh sheet <NUM>. As shown in <FIG>, the drainage bag <NUM> is similar to the drainage tube <NUM> in <FIG>. The seventh sheet <NUM> adjacent to the first sheet <NUM> may be replaced by extending the first sheet <NUM>. The end of the extending portion <NUM> of the first sheet <NUM> is connected with the bottom edge of the seventh sheet <NUM>. The top edge of the seventh sheet <NUM> is connected with the second sheet <NUM>. The drainage bag <NUM> is formed by connecting the two open side edges of the extending portion <NUM> and the seventh sheet <NUM>. An isolation material <NUM> is provided on either the surface of the seventh sheet <NUM> that faces the extending portion <NUM>, or the surface of the extending portion <NUM> that faces the seventh sheet <NUM>. The opening of the sixth sheet <NUM> is further covered with a cap <NUM> provided with a reusable adhesive, preventing a small amount of fluid from seeping. As shown in <FIG>, the drainage bag <NUM> is formed by folding an eighth sheet <NUM> in half and sealing all or part of the edges of the eighth sheet <NUM>. In the present embodiment, a drainage tube <NUM> is further being set up correspondingly to the opening of the sixth sheet <NUM>.

<FIG> show another embodiment of the present invention. A first drainage port <NUM> is formed at an open portion where the first sheet <NUM> and the part adjacent to the edge of the second sheet <NUM> are not welded or adhered to each other. As shown in <FIG>, the half-folded eighth sheet <NUM> in <FIG> is further replaced by the extending portion <NUM> of the first sheet <NUM> to form a drainage bag <NUM>. The drainage bag <NUM> is formed by connecting the first surface S1 of the extending first sheet <NUM> and the third surface S3 of the second sheet <NUM>, and then connecting the two open side edges of the half-folded extending portion <NUM>. Meanwhile, the second sheet <NUM> is provided with at least a second drainage port <NUM>, which enables the inside of the first chamber R1 to communicate with the outside through the second drainage port <NUM>. The second drainage port <NUM> is smaller than the inner edge of the band-shaped region <NUM>, thereby forming a distance between the second drainage port <NUM> and the inner edge of the band-shaped region <NUM>. The distance is preferably greater than <NUM>, more preferably greater than <NUM>, and most preferably greater than <NUM>. When the present invention is used as a semen collection device, the thickness of the first sheet <NUM>, the second sheet <NUM> and the seventh sheet <NUM> is preferably less than <NUM>, more preferably less than <NUM>, most preferably less than <NUM>. The perimeter of the second sheet <NUM> is preferably less than <NUM>, more preferably less than <NUM>, most preferably less than <NUM>. The widest part of the second sheet <NUM> is preferably less than <NUM>, more preferably less than <NUM>, most preferably less than <NUM>. The volume of the drainage bag <NUM> is preferably less than <NUM>, more preferably less than <NUM>, most preferably less than <NUM>. Lesser perimeter and thickness of the sheet can create a smaller and thinner body fluid collection device <NUM>, so as to increase pleasure during sexual intercourse. The volume is set with reference to the fact that the amount of sperm per ejaculate by male is generally no more than <NUM>. <FIG> shows another embodiment of the present invention for semen collection. Since the coronal sulcus adjacent to the frenulum of prepuce is the part that bears the strongest friction during thrusting activity, the first sheet <NUM> and the second sheet <NUM> in this area are connected with each other with the U-shaped/C-shaped band-shaped region <NUM>. The first chamber R1 is generally in a closed state during sexual intercourse, effectively preventing the first sheet <NUM> and the second sheet <NUM> from peeling off due to a pulling force that is caused by friction. <FIG> is a back view (also referring to <FIG>), where the second drainage port <NUM> extends from the center of the second sheet <NUM> to the top edge of the second sheet <NUM>, forming the second sheet <NUM> with an opened and U-shaped (or C-shaped/V-shaped) upper end. When in use, by adhering the fluid-carrying application <NUM> to a bedridden female's pudendum with the open end facing towards the female's pubis bones, the urine sample may be collected directly instead of using a catheter in an invasive method. The second sheet <NUM> with the design of an open end may prevent the difficulty in removing, which is caused by the adhesive layer <NUM> sticking to body hairs. The structure support unit <NUM> (not shown in the figure) may further extend outwards from the edge to form a pinch portion <NUM> protruding from the second sheet <NUM>. At least one point of the pinch portion <NUM> is connected to the structure support unit <NUM> for the ease of the user to adjust the position of the fluid-carrying application of the present invention before adhesion, or to remove the structure support unit <NUM> after adhesion while pinching with fingers.

<FIG> show another embodiment of the present invention. As shown in <FIG>, the drainage tube <NUM> has a wider cross section of the tube wall and an outer cross section generally same as the first drainage port <NUM>. The cap <NUM> or the cross section of the tube wall of one end of the drainage tube <NUM> is provided with a reusable adhesive, thereby the cap <NUM> is adhered to the drainage tube <NUM> in a removable way. Meanwhile, the second sheet <NUM> is provided with at least a second drainage port <NUM>. The user may inject drugs or skin care products through the drainage tube <NUM>. The fluid in the first chamber R1 may therefore contact the body surface directly through the second drainage port <NUM>, and the drugs or skin care products may be directly introduced to wounds or can be used to moisten skins directly. For the drugs that are absorbed through skins, the effect of preventing the loss of the drugs or avoiding clothes being stained may also be achieved. If there is the need to slower the effect of the fluid on bodies, a unidirectional or bidirectional osmosis membrane may be set up at the second drainage port <NUM> (as shown in <FIG>), such as gauze or meltblown nonwoven fabric. Alternatively, a plurality of second drainage ports <NUM> may be formed by processing at least a part of the second sheet <NUM>. Small and densely arranged openings enable the fluid to slowly permeate through the microporous membrane. Alternatively, when the user injects fluid, the liftable part <NUM> of the fifth sheet <NUM> may prevent the fluid from flowing out. A plurality of spotted/ribboned band-shaped regions <NUM> may be further set up at the range of the first chamber R1 (as shown in <FIG>, which is the front view of <FIG>) to form a plurality of small chambers that can communicate with one another in the first chamber R1. The distance between the first sheet <NUM> and the second sheet <NUM> is shorter (as shown in <FIG>), so that the best effect of immersion may be achieved by lesser fluids. Two side edges of the structure support unit <NUM> may be further provided with pinch portions <NUM> correspondingly for a user to operate at ease.

<FIG> is another embodiment of the present invention. The second sheet <NUM> is provided with a second drainage port <NUM>. The drainage portion is a drainage bag <NUM> being set up correspondingly to the first drainage port <NUM>. The drainage bag <NUM> may be formed by combining two seventh sheets <NUM> which is shown in <FIG>, or it may be as shown in the present embodiment, formed by folding the eighth sheet <NUM> in half and sealing all or part of the edges of the eighth sheet <NUM>. The edges of the eighth sheet <NUM> may be further provided with an unsealed open portion to form a drainage port of the drainage bag <NUM>. When in use, the second drainage port <NUM> is aligned with the urethral orifice and ostium vaginae of a female user, and the second sheet <NUM> is adhered to the vulva using the adhesive layer <NUM>, so that urine or menstrual blood may flow into the drainage bag <NUM> for storage. The drainage bag <NUM> may be further provided with a second drainage tube <NUM> for timely discharging body fluids. Additionally, the drainage bag <NUM> of the present embodiment may further comprise a structure with an non-return effect, and can prevent the fluid in the drainage bag <NUM> from flowing back to the first chamber R1. As shown in <FIG>, the first sheet <NUM> comprises a first liftable part <NUM>. The eight sheet <NUM>, which forms the drainage bag <NUM>, comprises a second liftable part <NUM> larger than the first liftable part <NUM>. The first sheet <NUM> and the eighth sheet <NUM> are connected in a enclosed manner in the form of surrounding the first liftable part <NUM> and the second liftable part <NUM>. At least a part of the first liftable part <NUM> is connected to the second liftable part <NUM> (welded or adhered). Since the size of the first liftable part <NUM> is smaller than the second liftable part <NUM>, the connection of the two parts may only be lifted towards the inside of the drainage bag <NUM>. Therefore, an effect of preventing backflow of the fluid in the drainage bag <NUM> may be achieved. It may be understood by those of ordinary skill in the art that if the drainage bag <NUM> is formed by two seventh sheets <NUM>, the seventh sheet <NUM> may likely be provided with a second liftable part <NUM> to prevent the fluid from flowing back.

<FIG> is another embodiment of the present invention. A flat operating portion <NUM> may be further set up at the drainage tube <NUM>, so that the user may open or close the drainage tube <NUM> with one hand fixing the drainage <NUM> and the other operating the cap <NUM>. When in use, the release layer <NUM> is first separated and peeled off. The second drainage port <NUM> is aligned with a nipple of a female and the second sheet <NUM> is adhered to the breast skin with the adhesive layer <NUM>. The cap <NUM> is then plugged into the drainage tube <NUM> by means of the elasticity and friction of material and close the drainage tube <NUM>. The user's milk may flow from the second drainage port <NUM> to the first chamber R1 and store in the first chamber R1. Then the user opens the drainage tube <NUM> to discharge the body fluid after selecting an appropriate place. The present invention may help breastfeeding mothers prevent staining clothes or unpleasant odor due to galactorrhea. When the second sheet <NUM> is adhered to a body surface that is arc-shaped, irregular fluctuated or fat, wrinkles are easily formed at the edge of the second drainage port <NUM>. Due to hydraulic pressure, fluids would leak from small channels formed at wrinkled area towards the edge of the second sheet <NUM>, eventually the second sheet <NUM> would peel off due to a gradually decreased adhesive strength of the adhesive layer <NUM>. Therefore, a structure support unit of the drainage port <NUM> may be further set up extending along the third surface S3 of the second sheet <NUM> and the edge surrounding the second drainage port <NUM> to maintain the shape of the second drainage port <NUM> and avoid leakage. By adjusting the adhesiveness of the structure support unit of the drainage port <NUM> (for example, by making the adhesiveness between the structure support unit of the drainage port <NUM> and the second sheet <NUM> weaker than the adhesiveness between the second sheet <NUM> and the human body through the adhesive layer <NUM>), after the second sheet <NUM> is adhered to the body surface, when the body surface forms wrinkles on the second sheet <NUM> due to squeezing or friction, the structure support unit of the drainage port <NUM> would peel off from the second sheet <NUM> due to the weak adhesiveness, therefore does not affect the adhesion between the edge of the second drainage port <NUM> and the body surface.

The embodiment of the present invention shown in <FIG> is for breastfeeding. The fluid-carrying application <NUM> is provided with detachable structures, such as but not limited to, an extending tube, a drainage bag, a pacifier or a valve. Referring to <FIG>, the second sheet <NUM> is provided with a second drainage port <NUM>. The drainage tube <NUM> is provided with an inner cross sectional area larger than the first drainage port <NUM>, so that the first chamber R1 has a better effect of sealing and leakproof. Additionally, the cap <NUM> may be further connected to a second drainage bag <NUM>. The second drainage bag <NUM> is set up correspondingly to a drainage port on the cap <NUM> on the cap <NUM>, therefore when the cap <NUM> is locked with the drainage tube <NUM>, the inside of the first chamber R1 is in communication with the inside of the second drainage bag <NUM> through the first drainage port <NUM>, the drainage tube <NUM> and the drainage port on the cap <NUM>, which may help breastfeeding mothers in milking and storing the milk. It may be understood by those of ordinary skill in the art that in the present embodiment, a second drainage bag <NUM> may also be directly connected to the drainage tube <NUM> for storing body fluids. As shown in <FIG>, a pacifier <NUM> may be further sandwiched between the drainage tube <NUM> and the cap <NUM>, in order to prevent the pain and damage of nipples due to breastfeeding. In the present embodiment, the cap <NUM> may also be connected to a valve, a cover, a switch or a sticker for opening or closing the drainage port on the cap <NUM> and discharging the milk to prevent clothes from staining due to galactorrhea. Alternatively, the cap <NUM> may be further connected to an extending tube <NUM> in order to drain the milk to a distal container. The set up of the brim portion <NUM> surrounding one end of the drainage tube <NUM> may be in the manner that, for example but not limited to, one of the brim portion <NUM> and the drainage tube <NUM> is provided with a flange and the other is provided with a concave flange so that the two are fixed with each other (as shown in <FIG>), the brim portion <NUM> and the drainage tube <NUM> are threadedly fixed with each other, the brim portion <NUM> and the drainage tube <NUM> are connected and formed integrally, or one of the brim portion <NUM> and the drainage tube <NUM> is plugged into the other by means of material elasticity and friction.

<FIG> is another embodiment of the present invention. Also referring to <FIG>, apart from a drainage tube <NUM> that comprises a detachable pacifier <NUM> and a cap <NUM>, another drainage tube <NUM> may be further set up on the first sheet <NUM> for injecting cow's milk and thus can help mothers with low milk supply. The second sheet <NUM> may be provided with a second drainage port <NUM>, so that the breast milk may flow into the first chamber R1 simultaneously. The second sheet <NUM> may also be a continuously closed sheet, so that a user who does not produce milk (such as fathers) may also feed babies.

<FIG> is another embodiment of the present invention. Also referring to <FIG> and <FIG>, apart from the liftable part <NUM> covering the first drainage port 12A, the fluid-carrying application <NUM> may be further provided with a third sheet <NUM> between the first sheet <NUM> and the second sheet <NUM>. The edge of the third sheet <NUM> is welded/adhered to the second sheet <NUM>, thereby forming a second chamber R2 between the third sheet <NUM> and the second sheet <NUM> (separated from the original first chamber R1). The part where the third surface S3 of the second sheet <NUM> and the edge of the third sheet <NUM> are not welded or adhered with each other forms an open portion, which is further connected to a second drainage tube <NUM>. The drainage tube <NUM> is sandwiched between the second sheet <NUM> and the third sheet <NUM> and passes through another first drainage port 12B, so that the inside of the second chamber R2 may be in communication with the outside through the second drainage tube <NUM>. When in use, the user may first adhere the fluid-carrying application <NUM> to the breast, inject air into the second chamber R2 through the second drainage tube <NUM>, and then inject water into the first chamber R1 through the first drainage port 12A. It may not only increase the size of the breast visually when the user wears clothes, but also alleviate the burden on the chest. It should be understood by those of ordinary skill in the art that the second drainage tube <NUM> may also be connected to a second drainage port <NUM> on the second sheet <NUM> (not shown in the figures). In the present embodiment, the second sheet <NUM> for adhering to the breast is a flat film, the third sheet <NUM> may be made of a flat or arc-shaped film, and the first sheet <NUM> is preferably made of an arc-shaped film.

<FIG> show another embodiment of the present invention. Also referring to <FIG>, <FIG> and <FIG>, as shown in <FIG> is the back view of <FIG> where a second sheet <NUM> is further processed into a second drainage port <NUM>), one embodiment of the fluid-carrying application <NUM> of the present invention is further providing a belt loop <NUM> on the drainage bag <NUM>. A fixing rope or a fixing belt may pass through the belt loop passage formed between the belt loop <NUM> and the drainage bag <NUM>, and thus the drainage bag <NUM> may be fixed on a part of the user's body. The drainage bag <NUM> may be further provided with a plurality of belt loops <NUM> so that the user may choose different fixing positions. As shown in <FIG>, when the drainage bag <NUM> is generally being set up parallel to legs, a plurality of belt loops <NUM> may be set up in a vertical direction, thus enhancing the stability of the drainage bag <NUM> as well as enabling the user to choose different belt loop passages to adjust and achieve the best fixing way. The belt loop <NUM> may be formed in the manner of, for example, connecting a belt loop sheet <NUM> with the drainage bag <NUM> by welding or adhering (but not limited to the above manner). For example, as shown in <FIG>, if the belt loop sheet <NUM> is rectangular, two opposite sides of the rectangle may be connected to the drainage bag <NUM>, or two or more points in the scope of the rectangle may be connected to the drainage bag <NUM>. Alternatively, as shown in <FIG>, by using and connecting a long-strip belt loop sheet <NUM> to three or more points of the drainage bag <NUM> along the long side of the long-strip belt loop sheet <NUM>, a plurality of belt loop passages may be formed. A button hole <NUM> may be further set up on the belt loop sheet <NUM> correspondingly to every belt loop passage. In combination with the fasteners on the fixing belt, the drainage bag <NUM> may be prevented from shifting along the fixing rope or the fixing belt.
