Abstract
Description
Technical Field
[0001] The present invention belongs to the field of medical and health care utensils, and specifically relates to a skin-friendly leak-proof gasket and its application method, a urinal using the leak-proof gasket, and a composite nursing auxiliary utensil. Background Art
[0002] Fluid leak-proof collection is of great significance in medicine and nursing, such as maintaining cleanliness, preventing the spread of infections, and facilitating management or disposal. This is not only reflected in well-known excreta and vomitus, but also in other fields such as wound fluid collection. Moreover, during the collection and nursing process, corresponding comfort and respect need to be provided to offer a more comfortable user experience and reduce discomfort to individuals. Specifically, for individuals who need to use wearable items, staying as dry and clean as possible can improve comfort. Therefore, it is necessary to enhance the sealing between the nursing collection utensil and the skin to improve the leak-proof effect.
[0003] For example, the part of the existing urinal that fits the skin and the urinal are made of the same material as a whole. This design leads to a contradiction: to maintain its shape, the urinal requires a certain hardness (Shore hardness 40 - 60) or a harder D-type material; in actual use, in order to maintain its normal functional shape, the urinal can only choose an appropriate hardness, resulting in the part that fits the skin being too hard to fully conform to the skin, leading to urine leakage. Summary of the Invention
[0004] Technical Problem: The technical problem to be solved by the present application is to provide a leak-proof gasket with high softness that improves the sealing performance by enhancing the skin-fitting effect, and to manufacture a urinal using this gasket to solve the problem of urine leakage at the skin-contact surface. And in combination with the fecal collection bag fixing seat disclosed in Chinese Invention CN115813649A, to provide a comprehensive nursing utensil for urine and feces, so as to improve the discomfort and nursing difficulty caused by urine leakage in the prior art.
[0005] Technical Solution: A skin-friendly leak-proof gasket includes a ring body and a coating layer. The ring body includes an adhesive surface and a contact surface, and the coating layer is applied to the contact surface. The Shore hardness of the ring body material is A0 - 25. The "adhesive" in the "adhesive surface" here does not refer to bonding with glue in a broad sense, but the purpose of this surface is to connect other leak-proof and liquid-conducting components in any connection manner.
[0006] Furthermore, the ring body material is silicone gel, and the coating layer is a water-based glue or a biological glue. This hardness of silicone gel material is usually used in women's breast pads, which provide functions such as support, decoration, or enhancing the visual effect of wearing options. Applying this material to the skin-friendly sealing for fluid leakage prevention has produced unexpected technical effects.
[0007] Furthermore, the contact surface between the rubber ring and the skin is provided with raised textures. The density of the textures is 0.3 mm - 2 mm, and the height of the texture protrusions is 0.2 mm - 0.5 mm. The human skin is not absolutely flat. Therefore, if the contact surface is too flat, even if a water-based glue or a bio-glue is applied, relative sliding is likely to occur, affecting the sealing effect. Therefore, setting textures on the contact surface is beneficial to improving the sealing performance.
[0008] Furthermore, the main body of the ring body is annular. The shape of the annular surface is designed according to the shape of the liquid guiding component and the body contact surface. The bonding surface and the contact surface are respectively located on the outer side walls of both sides of the ring body along the central axis. That is, when the gasket is laid flat on the skin, the side in contact with the skin is the contact surface, and the side opposite to the contact surface is the bonding surface. The bonding surface is used to connect the liquid guiding component. The shape of the contact surface can refer to the shape of the prior art that has been made public, and can be made into a shape that bends inward along the whole body, or can also be directly made into a solid shape, because the softness of the material itself can already solve the comfort problem.
[0009] In this application, the application method of the leak-proof gasket is used for leak-proof liquid treatment. When applied, the contact surface coated with the water-based glue contacts the human skin to play a sealing role. The bonding surface connects the necessary liquid guiding components.
[0010] Furthermore, the first bonding method is to apply an adhesive on the bonding surface to bond with the liquid guiding component.
[0011] Furthermore, the second bonding method is to provide a limit protrusion / groove along the circumference on the bonding surface, and a corresponding groove / protrusion is provided on the liquid guiding component. The leak-proof gasket and the liquid guiding component are connected by embedding the limit protrusion into the groove.
[0012] Furthermore, it also includes a connecting piece.
[0013] The Shore hardness of the connecting piece is greater than that of the leak-proof gasket or the liquid guiding component.
[0014] The connecting piece is annular in front view, and its side view is vertical or the upper and lower ends are bent towards one side.
[0015] When the leak-proof gasket is connected, part or all of the bonding surface of the leak-proof gasket wraps the outer edge of the connecting piece, and the two form an intermediate assembly with the leak-proof gasket.
[0016] An inward wrapping opening is provided at the interface of the liquid guiding component, and a circumferential limit groove is provided below the wrapping opening.
[0017] When the intermediate assembly is connected to the liquid guiding component, the intermediate assembly is embedded inside the groove.
[0018] Furthermore, the liquid guiding component is made of an elastic material, and the connection between the liquid guiding component and the intermediate assembly adopts an interference fit.
[0019] Furthermore, the third bonding method is to use layered injection molding to integrally mold the leak-proof gasket and the liquid guide component.
[0020] The present application also provides a urinal, including a urinal body, a feces receiving port is formed on the urinal body, the feces receiving port is connected to the above-mentioned leak-proof gasket, and the urinal body and the leak-proof gasket are connected using the above-mentioned three connection methods or other connection methods.
[0021] Furthermore, the bucket body is made of an elastic material with a Shore hardness of A50-60. The urinal body is still made of a material with a Shore hardness of 50-60 to maintain its overall shape and meet the function of collecting urine.
[0022] Furthermore, the elastic material is silicone, which is the most suitable material among the existing known materials because of its lightness and convenience for injection molding.
[0023] Furthermore, a support ring is arranged inside the urinal, and the support ring has the same shape as the fecal inlet, so as to support the urinal and avoid deformation during use.
[0024] Furthermore, a connection seat is provided at the lower edge of the toilet opening, and the connection seat is used for wearing and / or connecting other nursing appliances.
[0025] Furthermore, Velcro is provided on the connection seat. By changing the force arrangement of the fixed points, the present application changes the four "point" force arrangement of the existing urinal's four-button buckle into two "surface" force arrangements of two Velcros. Specifically, the upper and lower parts of the urinal are connected to the fixed shorts and the rear connecting belt respectively through Velcro, and the force direction is divided into two front and rear force surfaces. When the whole is pulled upward, it can well prevent the urinal from being deformed due to uneven force, and avoid the formation of gaps that cause urine leakage.
[0026] A composite nursing auxiliary tool comprises the aforementioned urinal and a stool bag fixing seat matched with the urinal. It can realize integrated defecation and urination care. The stool bag fixing seat can refer to the stool bag fixing seat disclosed in Chinese invention CN115813649A. By improving the sealing performance of the urinal, the urine leakage function is improved, thereby improving the overall performance of the composite nursing auxiliary tool.
[0027] The beneficial effects of the present invention are:
[0028] 1. By adopting silicone gel material and water-based glue / biological glue coating layer, as well as setting raised texture, the sealing between the leak-proof gasket and the skin can be effectively improved. It helps to prevent body fluid leakage and keep it dry and clean.
[0029] Silicone gel materials with a Shore hardness of A0 - 5 are usually applied to women's breast stickers, which are in the field of visual effect functions that provide decoration or increase wearing options. Applying this material to the medical care field of skin - tight sealing against body fluids leakage has produced unexpected technical effects.
[0030] 2. Silicone gel materials with low Shore hardness have good softness and elasticity, can fit well with the human skin, and provide a comfortable use experience. At the same time, the circular design of the ring body matches the shape of the body - fitting surface, ensuring the degree of fit between the gasket and the body.
[0031] 3. The leak - proof gasket provides a variety of connection methods, including adhesive glue, limit protrusions and card slots, layered injection molding, etc., for connecting with the liquid - guiding component. In this way, the most suitable connection method can be selected according to specific requirements to ensure a firm connection between the leak - proof gasket and the liquid - guiding component.
[0032] Especially the assembly connection method is equivalent to clamping a part of the leak - proof gasket between the connecting piece and the urinal (liquid - guiding component), solving the problem of assembling hard - soft binary materials.
[0033] 4. For the design of the urinal, it is made of an elastic material with a Shore hardness of A50 - 60 to maintain the overall shape of the urinal body; and by changing the force arrangement of the magic tape, the sealing performance and anti - deformation ability are improved, effectively preventing urine leakage and the generation of gaps. 5. In the composite nursing auxiliary appliance, the leak - proof gasket is connected in a supporting way with the stool - receiving urinal, and a stool - receiving bag fixing seat is equipped, further improving the overall performance of the existing composite nursing appliance.
[0034] The composite nursing appliance connected with the stool - receiving bag fixing seat can change the wearing method of the urinal. Specifically, in the existing wearing of the urinal, the wearing connecting belt needs to bypass the anus position. Either it is connected to the waist belt by means of diagonal pulling, or the lower connecting belt needs to be wound around the leg for wearing. Both of these methods increase the length of the wearing connecting belt. During long - term wearing, the elastic fatigue degree will accumulate, that is, the longer the connecting belt, the looser the later wearing will be. Therefore, this is also a major factor leading to urine leakage.
[0035] However, the stool - receiving bag fixing seat itself is provided with a defecation hole and can be lifted vertically backward for wearing, which not only improves the force - bearing mode of the urinal, reduces the possibility of urine leakage, but also can perform stool care by connecting a stool - receiving bag.
