[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation
[0017] As attached Figs. 1-3 As shown, in this embodiment, a urine collector includes a fixing component 1, which includes a diaper body 11 and connecting straps 12 connected to both sides of the diaper body 11; and an outlet component 2, which includes a collection member 21 connected to the middle of the bottom end of the diaper body 11, a connector 22 connected to the collection member 21, and an outlet pipe 23 connected to the connector 22, with a negative pressure absorber connected to the outlet pipe 23.
[0018] The diaper body 11 is used to wrap the patient's lower body. It is made of soft, skin-friendly non-woven fabric to ensure comfort during prolonged wear. The connecting strap 12 securely fastens the diaper body 11 to the patient's body. Its elastic material adapts to patients of different body types, and the elastic strap 12 allows for flexible adjustment of tightness according to the patient's needs. The collection unit 21 collects urine discharged from the absorbent section of the diaper body 11 and directs it through the discharge tube 23 and the external negative pressure absorber into a storage container. This reduces the need for frequent diaper changes and prevents leakage.
[0019] In use, the diaper body 11 is worn on the patient's lower body and secured with the connecting strap 12, adjusting the tightness to a suitable level according to the patient's body shape. After the patient urinates, the urine is first absorbed by the diaper body 11, and then effectively collected and discharged through the collection component 21 and the connecting component 22. This avoids urine accumulation inside the diaper, reduces skin problems caused by prolonged contact with the skin, improves patient comfort, and also reduces the workload of caregivers. Specific Implementation
[0020] As attached Figs. 1-3 As shown, in this embodiment, the diaper body 11 includes an absorbent portion 111 located in the middle and a fixing portion 112 located on the side of the absorbent portion 111.
[0021] The inner side of the absorption section 111 is provided with a plurality of drain holes 113, which are connected to the liquid collection vessel 211.
[0022] The absorbent part 111 is made of a highly absorbent material, which can quickly absorb and lock in urine, prevent urine backflow, and keep the patient's skin dry. Drainage holes 113 are evenly distributed on the inner side of the absorbent part 111 to ensure smooth urine drainage. The inner side of the fixing part 112 is made of elastic non-woven fabric, and the outer side of the fixing part 112 is made of waterproof material, which can effectively prevent urine leakage. Specific Implementation
[0023] As attached Figs. 1-3 As shown, in this embodiment, the collection unit 21 includes a liquid collection vessel 211 connected to the absorption unit 111, and a drain pipe 212 connected to the liquid collection vessel 211.
[0024] The collection container 211 is made of transparent medical-grade plastic, allowing medical staff to easily observe the amount of urine collected. The drain tube 212 is made of flexible silicone, with an inner diameter of 8mm and a length of 15cm, and its bending angle can be adjusted according to the patient's position without affecting urine flow. During use, the patient's urine enters the collection container 211 through the drain hole 113, and then flows through the connected drain tube 212 and outlet tube 23, passing through a negative pressure absorber into the storage tank. This prevents urine accumulation in the diaper and reduces the inconvenience of frequent changes. The connection between the drain tube 212 and the collection container 211 is tight, preventing the risk of urine leakage.
[0025] The connecting part 22 includes a positioning seat 221 fixedly connected to the drain pipe 212, and a connecting sleeve 222 slidably disposed at the end of the drain pipe 23 and threadedly connected to the positioning seat 221.
[0026] The front side of the positioning seat 221 is provided with multiple movable slots 223.
[0027] In use, the positioning seat 221 is fixedly mounted on the end of the drain pipe 212, and the end of the outlet pipe 23 is inserted into the positioning seat 221. A sealing ring is provided at the connection between the end of the outlet pipe 23 and the positioning seat 221, and then the connecting sleeve 222 is threadedly connected to the positioning seat 221. The connecting sleeve 222 gradually tightens during rotation, ensuring a tight and leak-free connection between the outlet pipe 23 and the drain pipe 212. The movable groove 223 provides the positioning seat 221 with a certain degree of elasticity, facilitating the installation and removal of the connecting sleeve 222 and enhancing the stability of the connection. When it is necessary to replace or stop using the urine collector, simply unscrew the connecting sleeve 222 to easily separate the outlet pipe 23 and the drain pipe 212, making the operation simple and quick. Specific Implementation
[0028] As attached Figs. 1-3 As shown in this embodiment, a fixing strip 114 is provided on the outer side of the end of the fixing part 111, and the fixing strip 114 is movably connected to the connecting belt 12.
[0029] The fixing part 111 is provided with an elastic strip 115 on one end of the connecting strap 12.
[0030] The fixing strip 114 is made of Velcro and is designed to correspond with the Velcro at the end of the connecting strap 12, allowing the connecting strap 12 to be flexibly adjusted in position according to the patient's body shape and needs, and ensuring a secure connection that is not easily detached. The elastic strip 115 has a certain degree of elasticity, which can act as a cushion during patient movement, reducing friction between the diaper body 11 and the patient's body, while also better conforming to the patient's body curves to prevent urine leakage. After the patient puts on the diaper body 11, the connecting strap 12 is fixed in the appropriate position using the fixing strip 114. The elastic strip 115 will automatically adjust according to the patient's body movements, ensuring that the entire urine collector is securely and comfortably fixed to the patient.
[0031] Working principle explanation: In use, the diaper body 11 is first placed on the patient's lower body in a suitable position, using the elasticity of the elastic strip 115 to conform to the patient's body curves. The connecting strap 12 is connected to the fastener 114 on the outer side of the fixing strip 114 at the end of the fixing part 111 via Velcro. The fixing position of the connecting strap 12 can be flexibly adjusted according to the patient's body shape and needs to securely fix the diaper body 11 to the patient's body. At this time, the elastic strip 115 acts as a cushion during patient movement, reducing friction between the diaper body 11 and the patient's body. After the patient urinates, the urine is first quickly absorbed and locked by the absorbent part 111, which is made of highly absorbent material, preventing urine backflow and keeping the patient's skin dry. Multiple drainage holes 113 evenly distributed on the inner side of the absorbent part 111 smoothly drain the urine into the collection container 211 connected to the absorbent part 111. The collection container 211 is made of transparent medical-grade plastic, making it easy for medical staff to observe the amount of urine collected. Urine then flows from the collection vessel 211 into the connected drain pipe 212. The drain pipe 212 is made of flexible silicone and can adjust its bending angle according to the patient's position without affecting the flow of urine. The positioning seat 221 is fixedly installed at the end of the drain pipe 212. The end of the outlet pipe 23 is inserted into the positioning seat 221, and a sealing ring is provided at the connection between the end of the outlet pipe 23 and the positioning seat 221. The connecting sleeve 222, which is slidably installed at the end of the outlet pipe 23, is then threadedly connected to the positioning seat 221. The connecting sleeve 222 gradually tightens during rotation to ensure a tight and leak-free connection between the outlet pipe 23 and the drain pipe 212. At the same time, the multiple movable grooves 223 on the front side of the positioning seat 221 give it a certain degree of elasticity, which facilitates the installation and removal of the connecting sleeve 222 and enhances the stability of the connection. Finally, the urine flows through the outlet tube 23 and the external negative pressure absorber into the storage tank, preventing urine accumulation in the diaper and reducing skin problems such as diaper rash caused by prolonged contact with the skin. It also prevents leakage, improving patient comfort and reducing nursing workload. When it is necessary to replace or discontinue the urine collector, simply unscrew the connecting sleeve 222 to easily separate the outlet tube 23 and the drain tube 212; the operation is simple and quick.
[0032] The preferred embodiments have been shown and described, but should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
