Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially, and it is female catheter convenient for measuring urine leakage. BACKGROUND

[0002] Catheter is a common medical supply in the nursing of critical patient monitoring, ICU, vegetable person monitoring and the like. The catheter can be generally divided into male and female, and there is a certain difference in use. At present, when female patients cannot get up to urinate due to urine retention, postoperative braking, coma, inconvenience in movement, long-term bedridden and other reasons, a catheter or a urine pad is generally used. When the catheter is used, since the air bag of the catheter cannot completely block the sphincter or the sphincter is relaxed or disturbed unconsciously, urine will seep along the outer wall of the catheter and leak out of the urethral orifice, which not only pollutes the sickbed, but also causes the skin near the urethral orifice to be red and inflamed, etc., which not only makes the patient uncomfortable, but also increases the workload and nursing difficulty of medical staff. When the urine pad is used, it is generally laid under the buttocks of the patient to directly absorb the urine when the patient urinates. However, in actual situations, urine may come into contact with the skin, causing discomfort and possibly causing wetness dermatitis and even pressure sores. Moreover, the general urine pad cannot well judge the amount of urine absorption, resulting in certain inconvenience.

[0003] Especially the catheter, at present, when urine leakage occurs, the catheter is generally replaced. However, the replacement of the catheter not only has high cost, but also is troublesome in the replacement process, and there is a risk that the urine leakage cannot be completely solved. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the utility model aims to provide a female catheter convenient for measuring urine leakage, which is provided with a urine leakage prevention structure. When the catheter is used, the urine leakage can be avoided, and the amount of urine leakage can be known, so that the catheter can be replaced conveniently.

[0005] The utility model solves the above technical problems through the following technical means:

[0006] The female catheter convenient for measuring urine leakage comprises a catheter, a urine leakage prevention structure is detachably arranged on the catheter, the urine leakage prevention structure comprises a liquid absorption unit, a fastening unit and a color development unit, the liquid absorption unit is detachably arranged on the catheter through the fastening unit, the color development unit is arranged in the liquid absorption unit, and different colors are displayed according to the amount of urine absorbed by the liquid absorption unit.

[0007] On the basis of the above scheme, the following improvements are made in the present application:

[0008] Furthermore, the absorbent unit is configured with an absorbent material, which has a through hole along its central axis for fitting with a urinary catheter, and the absorbent material has a through notch that communicates with the through hole.

[0009] According to the above-mentioned technical means, by setting through holes and notches on the absorbent material, the absorbent material can be made into an openable type, which facilitates the assembly of the absorbent material before use and the removal of the absorbent material after use.

[0010] Furthermore, one end of the absorbent material is cylindrical, and the other end is conical.

[0011] According to the above-mentioned technical means, by limiting the shape of the absorbent material to a round strip with a narrowed top, it is easier for the absorbent material to come into contact with the urethral opening, thereby avoiding urine leakage.

[0012] Furthermore, the color-developing unit is configured as a color-developing area, which extends from the inner surface to the surface of the liquid-absorbing unit.

[0013] Based on the above-mentioned technical means, the amount of urine absorbed in the aspiration unit can be known by the color change of the hot melt adhesive urine display area or the ink urine display area, which makes it easier for medical staff to determine whether the aspiration material needs to be replaced. It is simple and convenient.

[0014] Furthermore, the fastening unit is configured as an elastic buckle, the elastic buckle has a slit extending along the length of the elastic buckle, the liquid absorption unit covers the elastic buckle, and the length of the liquid absorption unit is greater than the length of the elastic buckle.

[0015] According to the above-mentioned technical means, by using elastic buckles to fasten the catheter, the aspiration unit can be firmly installed on the catheter without affecting the absorption of leaked urine by the aspiration unit.

[0016] Furthermore, the fastening unit is configured as an adhesive tape, which is adhered to the outer surface of the liquid absorption unit.

[0017] Based on the above-mentioned technical means, the liquid absorption unit is fixed to the urinary catheter using adhesive tape, which is simple and highly practical.

[0018] Furthermore, the liquid absorption unit is configured as a water-absorbing material, which includes a base layer and a surface layer. The base layer and the surface layer are detachably connected, and the base layer and the surface layer have communicating connection holes. The fastening unit is disposed in the communicating holes, and the color developing unit extends from the surface layer to the base layer and is located on the outer surface of the base layer.

[0019] Based on the above-mentioned technical means, by dividing the absorbent material into a base layer and a surface layer, it is formed into an arc-shaped sheet. The surface layer is attached to the urethral opening, so that when urine leakage occurs, it can absorb the leakage from all directions, which is especially suitable for female patients to prevent urinary leakage. Furthermore, by connecting the base layer and the surface layer, not only can the absorption of urine leakage be increased, but the outer surface of the base layer can also be colored, so that the amount of urine leakage absorbed by the absorbent material can be known.

[0020] Furthermore, the base layer includes a body, a foldable layer, and an extension layer. The body has a receiving position, the foldable layer is connected to the body and located at the bottom of the receiving position, the extension layer is connected to the body and located at the top of the receiving position, and the foldable layer is bonded to the extension layer.

[0021] Based on the above technical means, by setting a foldable layer and an extension layer on the main body, the main body can have two forms: open and closed. When the foldable layer and the extension layer are closed, leakage can be prevented. When the foldable layer is open relative to the extension layer, the main body can be removed from the catheter for replacement.

[0022] Furthermore, the surface layer includes a first surface layer and a second surface layer, which are symmetrically arranged and fixedly connected to the fastening unit.

[0023] According to the above-mentioned technical means, by dividing the surface layer into a first surface layer and a second surface layer, it is convenient for the surface layer to be separated when the absorbent material is disassembled, so that it can be removed from the catheter.

[0024] Furthermore, the first and second surface layers have the same structure, with the outer surface of the first surface layer being arc-shaped and gradually flattening outwards towards the fastening unit.

[0025] Based on the above-mentioned technical means, by changing the surface height of the surface layer, it is beneficial to fit the urethral opening, thereby absorbing urine leakage in all directions.

[0026] The present application, employing the above-described scheme, has the following beneficial effects:

[0027] 1. In this application, by setting a detachable anti-leakage structure on the urinary catheter, the anti-leakage structure can seal the outer wall of the urinary catheter and the area around the urethral opening when it comes into contact with the urethral opening, thereby preventing leakage and making it easier to know the amount of leakage and to replace it in a timely manner.

[0028] 2. In this application, the detachable leak-proof structure is configured as an aspiration unit, a fastening unit, and a color-displaying unit. The aspiration unit absorbs leaked urine, and the color-displaying unit displays the amount of leaked urine absorbed by the aspiration unit, thereby measuring the amount of leaked urine and making it easy to know the amount of urine absorbed by the aspiration unit. The fastening unit detachably fixes the aspiration unit to the catheter, making it easy for medical staff to replace. It is simple and highly practical.

[0029] 3. In this application, by setting the liquid absorption unit as a tapered strip or arc-shaped sheet, it can not only fit the female urethral opening, but also seal the urethral opening and the outer wall of the catheter, thereby effectively preventing urine leakage; moreover, the liquid absorption unit in this application is not only easy to disassemble, but also can measure the amount of urine leakage absorbed, making it highly practical.

In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the figures are only for illustrative purposes and should not be construed as limiting the present utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances. In the description of this application, terms such as "first", "second", etc. are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0043] like Figures 1-7 As shown in the figure, this application discloses a female urinary catheter 1 for easy measurement of urine leakage, including a urinary catheter 1. A detachable anti-leakage structure 100 is detachably provided on the urinary catheter 1. By providing a detachable anti-leakage structure 100, when in contact with the urethral opening, the anti-leakage structure 100 can seal the outer wall of the urinary catheter 1 and the area around the urethral opening, thereby preventing urine leakage and making it easy to know the amount of leakage for timely replacement.

[0044] In some embodiments, the leak-proof structure 100 includes an aspiration unit, a fastening unit, and a color-displaying unit 3. The aspiration unit is detachably mounted on the catheter 1 via the fastening unit. The color-displaying unit 3 is disposed within the aspiration unit and extends from the inside out. It displays different colors according to the amount of urine absorbed by the aspiration unit, allowing color changes to be observed on the surface of the aspiration unit. Based on these color changes, the amount of urine leakage can be determined, enabling healthcare personnel to replace the catheter promptly.

[0045] In an optional embodiment, such as Figures 1-2 As shown, the absorbent unit is composed of absorbent material 2, one end of which is cylindrical and the other end is conical. By defining the shape of the absorbent material 2 as a tapered strip with a narrowed top, it facilitates contact between the absorbent material 2 and the female urethral opening, thereby preventing urine leakage. The absorbent material 2 has a through hole along its central axis for fitting with the catheter 1. The absorbent material 2 also has a through notch 21 that communicates with the through hole, thus making the strip-shaped absorbent material 2 openable and closable, facilitating assembly before use and removal after use.

[0046] In one implementation, such as Figure 1 As shown, the fastening unit is an elastic buckle 4. The elastic buckle 4 has a slit 41 extending along its length. The absorbent material 2 is adhesively wrapped around the elastic buckle 4, allowing it to be securely fastened to the catheter 1. When removing the catheter, the absorbent material 2 can be opened by prying open the elastic buckle 4, facilitating removal and replacement. The length of the absorbent material 2 is greater than the length of the elastic buckle 4, ensuring that the top of the absorbent material 2 covers the elastic buckle 4, preventing contact with the urethral opening while ensuring the top of the absorbent material 2 fits snugly against the catheter 1, preventing leakage.

[0047] In this embodiment, the color-developing unit 3 is set as a color-developing area. The color-developing area extends from the inner surface to the surface of the absorbent unit, so that the surface of the absorbent material 2 can change color, so that medical staff can see it intuitively and judge the amount of urine absorbed based on the color change, and then judge whether it needs to be replaced.

[0048] In this embodiment, the color-developing area is set as a hot melt adhesive urine-developing area or an ink urine-developing area. That is, the color-developing area is formed by mixing the hot melt adhesive urine-developing material or the ink urine-developing material with the absorbent material 2, and a portion of the hot melt adhesive urine-developing material or the ink urine-developing material is located on the inner surface of the absorbent material 2 and continuously located on the outer surface. It can be in the form of vertical strips or rings, so that the hot melt adhesive urine-developing material or the ink urine-developing material can change color after absorbing urine, and the color change can be observed on the surface of the absorbent material 2.

[0049] In this embodiment, both hot melt adhesive urine-displaying materials and ink urine-displaying materials are existing technologies and will not be described in detail here.

[0050] In another implementation, such as Figure 2 As shown, the fastening unit is set as adhesive tape 5, preferably transparent adhesive tape 5. The adhesive tape 5 is adhered to the outer surface of the absorbent material 2, thereby fixing the absorbent material 2 to the catheter 1 through the adhesion of the adhesive tape 5. The operation is simple and practical. After the hot melt adhesive urine indicator material or ink urine indicator material is mixed with the absorbent material 2, a part of the hot melt adhesive urine indicator material or ink urine indicator material is located on the inner surface of the absorbent material 2 and continuously located on the outer surface. It can be vertical or ring-shaped, so that the hot melt adhesive urine indicator material or ink urine indicator material can change color after absorbing urine, and the color change can be observed on the surface of the absorbent material 2. In this embodiment, the hot melt adhesive urine indicator material or ink urine indicator material are existing technologies and will not be described in detail here.

[0051] In this embodiment, the absorbent material 2 can be set as a sponge, cotton strip, super absorbent polymer (SAP), etc., and appropriate materials can be selected according to the actual situation.

[0052] In some embodiments, such as Figures 3-7 As shown, the absorbent material 2 can be further divided into a base layer and a surface layer 24, which are detachably connected to facilitate the assembly and disassembly of the absorbent material 2 and the catheter 1. The base layer and surface layer 24 have communicating connection holes, and fastening units are disposed within these holes to detachably secure the absorbent material 2 to the catheter 1. A color-developing unit 3 extends from the surface layer 24 towards the base layer and is located on the outer surface of the base layer, allowing the amount of urine absorbed by the absorbent material 2 to be observed on the outer surface of the base layer, and the amount of urine absorbed to be measured based on the color change of the color-developing unit 3.

[0053] By dividing the absorbent material 2 into a base layer and a surface layer 24, forming an arc-shaped sheet, the surface layer 24 is placed against the female urethral opening, thus absorbing urine from all directions when leakage occurs, making it especially suitable for female patients to prevent urinary leakage. Furthermore, by connecting the base layer and the surface layer 24, not only can the absorption of urine leakage be increased, but the outer surface of the base layer can also be colored, so that the amount of urine leakage absorbed by the absorbent material 2 can be known.

[0054] In this embodiment, the color-developing unit 3 is a hot melt adhesive urine-developing material or an ink urine-developing material. After being mixed with the base layer and surface layer 24 of the absorbent material 2, a portion of the hot melt adhesive urine-developing material or the ink urine-developing material is located on the surface layer 24 of the absorbent material 2 and is continuously located on the outer surface of the base layer.

[0055] In this embodiment, as Figure 7As shown, the fastening unit is preferably an elastic buckle 4, with one end of the elastic buckle 4 located inside the communicating hole and the other end located outside the communicating hole, facilitating the assembly and opening of the elastic buckle 4 with the catheter 1. The areas of the base layer and the surface layer 24 that contact the elastic buckle 4 are fixedly connected by adhesive.

[0056] In this embodiment, as Figures 4-6 As shown, the base layer includes a main body 20, a foldable layer 22, and an extension layer 23. The main body 20 has a receiving position 201. The foldable layer 22 is connected to the main body 20 and located at the bottom of the receiving position 201. The extension layer 23 is connected to the main body 20 and located at the top of the receiving position 201. The foldable layer 22 and the extension layer 23 are attached together. By providing the foldable layer 22 and the extension layer 23 on the main body 20, the main body 20 can have both open and closed forms. When the foldable layer 22 and the extension layer 23 are closed, leakage prevention is achieved. When the foldable layer 22 is open relative to the extension layer 23, the main body 20 can be detached from the catheter 1 for replacement.

[0057] In this embodiment, as Figure 4 As shown, the outer layer 24 includes a first outer layer 241 and a second outer layer 242, which are symmetrically arranged and connected to the elastic buckle 4 by adhesive. In other embodiments, the first outer layer 241 and the second outer layer 242 can also be sewn to the body 20 separately with needle and thread, so that when the foldable layer 22 is opened and the body 20 is removed, the first outer layer 241 and the second outer layer 242 can be separated, thereby removing the absorbent material 2 from the catheter 1.

[0058] In this embodiment, the first surface layer 241 and the second surface layer 242 have the same structure. The following description uses the first surface layer 241 as an example. The outer surface of the first surface layer 241 is arc-shaped and gradually flattens away from the elastic buckle 4, creating a change in surface height. This facilitates a close fit with the urethral opening, thereby absorbing urine leakage from all directions. Furthermore, a certain protrusion is formed at the top junction of the first surface layer 241 and the second surface layer 242, which can seal the catheter 1, preventing urine leakage along the outer wall of the catheter 1, and further ensuring a close fit with the urethral opening.

[0059] In this embodiment, a breathable sticker can also be provided on the edge of the main body 20 so that the absorbent material 2 can adhere to the skin through the breathable sticker when in use, thus preventing the absorbent material 2 from detaching from the urethral opening due to the patient's accidental movements.

[0060] In this embodiment, catheter 1 is a catheter with an air balloon.

[0061] The above provides a detailed description of a female urinary catheter for convenient measurement of urine leakage, as provided in this application. The specific embodiments are described only to aid in understanding the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
