Description

Technical Field

[0001] This utility model relates to the field of medical and nursing care products technology, specifically to a leak-proof and antibacterial medical catheter. Background Technology

[0002] Medical catheterization pants are generally used to assist patients with urination. Their structural design facilitates urine collection and drainage while preventing soiling of clothing or bed sheets. However, existing medical catheterization pants still have some shortcomings in practical use, such as limited leak-proof performance, insufficient antibacterial effect, and insufficient adaptability to patient activity. A search revealed a design in CN110338491B, a pair of pants for patients undergoing intermittent catheterization, published on December 22, 2023. This design uses zippers and buttons for easy operation by medical staff, but the diaper pads only partially absorb urine, making it difficult to effectively prevent leakage, especially during patient activity where side leakage is prone to occur. Furthermore, this design lacks antibacterial functionality, which may lead to bacterial growth and increase the risk of infection. Another design, CN114128943B, published on January 30, 2024, uses a fixing device to achieve quick installation of the drainage auxiliary device. However, it still suffers from urine diffusion and leakage problems, and similarly lacks antibacterial measures. Long-term use may pose health risks due to urine residue. These issues indicate that existing medical catheters have limitations in terms of leak prevention and antibacterial properties, and urgently need improvement to better meet patient needs.

[0029] This utility model provides a leak-proof and antibacterial medical catheter, the specific implementation of which is as follows. Figure 1 As shown, the diaper includes a pant body 1, a drainage component 2, and an antibacterial layer 3. The crotch area of ​​the pant body 1 has a drainage groove 4, which extends along the length of the pant body 1 and communicates with the drainage component 2. The drainage component 2 consists of a drainage cavity and a partition plate, which divides the drainage cavity into upper and lower layers: an upper drainage channel 5 and a lower fluid storage cavity 6. A flexible sealing strip 7 is provided at the entrance of the drainage channel 5. The two sides of the flexible sealing strip 7 are fixed to the inner wall of the drainage cavity by elastic connectors, and the middle of the flexible sealing strip 7 is arc-shaped and conforms to the patient's perineal area. A drain port 8 is provided at the bottom of the fluid storage cavity 6, and the drain port 8 is connected to a sealing cap by threads.

[0030] like Figure 2As shown, in the layered structure of the drainage cavity, the inner wall of the drainage channel 5 is provided with multiple guide plates 12, which are evenly distributed along the length of the drainage channel 5. Each guide plate 12 has an arc-shaped cross-section, with the arc protrusion facing the center line of the drainage channel 5. The surface of the guide plate 12 is coated with a hydrophobic coating. Adjustable elastic bands 10 are provided on both sides of the drainage cavity. One end of the elastic band 10 is sewn to the outer wall of the drainage cavity, and the other end is connected to the waist of the pants 1 via Velcro. The elastic band 10 has a memory alloy wire 11 inside, and the two ends of the memory alloy wire 11 are fixed to the two ends of the elastic band 10 respectively.

[0031] like Figure 3 As shown, the inner wall of the storage chamber 6 is provided with an absorbent core layer 13, which is made of superabsorbent polymer resin. The outer side of the absorbent core layer 13 is wrapped with a waterproof membrane 14. The absorbent core layer 13 is fixed to the inner wall of the storage chamber 6 by a hot-pressing process. The bottom of the storage chamber 6 is provided with a drain port 8, which is connected to a sealing cap by threads for periodically cleaning the urine in the storage chamber 6.

[0032] like Figure 4 As shown, the waistband of the trousers 1 has an elastic tightening ring 15, and a silicone pad 16 is provided on the inner side of the elastic tightening ring 15. The surface of the silicone pad 16 has an anti-slip texture. The two ends of the elastic tightening ring 15 are fixed to the waistband of the trousers 1 by stitches. A coil spring is provided inside the elastic tightening ring 15, and the two ends of the coil spring are welded to the two ends of the elastic tightening ring 15 respectively. The design of the elastic tightening ring 15 ensures that the trousers 1 maintain a close fit when the patient moves.

[0033] like Figure 5 As shown, a temperature sensing module 17 is provided on the outer side of the antibacterial layer 3, and a display screen 18 is provided on the surface of the temperature sensing module 17. The temperature sensing module 17 contains a temperature sensor and a microprocessor. The probe of the temperature sensor contacts the inner surface of the antibacterial layer 3, the microprocessor is electrically connected to the temperature sensor, and the output of the microprocessor is electrically connected to the display screen 18. The power interface of the temperature sensing module 17 is located on the outer side of the trouser body 1, and the power interface is connected to an external power source via a wire. The design of the temperature sensing module 17 enables real-time monitoring of temperature changes in the antibacterial layer 3 and displays the results on the display screen 18.

[0034] A protective cover 19, which is semi-circular in shape, is provided at the front end of the flow guide cavity. A cushioning pad made of polyurethane foam is provided on the inner side of the protective cover 19. A handle made of rigid plastic is provided on the outer side of the protective cover 19. The design of the protective cover 19 can protect the front end area of ​​the flow guide cavity to a certain extent.

[0035] The leg openings of the trousers 1 are equipped with elastic cuffs. The inside of the elastic cuffs has an anti-chafing pad made of cotton fabric. The two ends of the elastic cuffs are secured to the leg openings of the trousers 1 with stitching. An internal tension spring is installed in the elastic cuffs, with its two ends welded to the ends of the elastic cuffs. The elastic cuff design prevents the trousers 1 from shifting or loosening during patient movement.

[0036] An exhaust port 20 is provided at the rear end of the flow guide cavity. A filter screen is provided inside the exhaust port 20. A dust cover is provided on the outside of the exhaust port 20, and the dust cover is connected to the outer wall of the flow guide cavity by a hinge. The design of the exhaust port 20 can effectively discharge the gas in the flow guide cavity while preventing external pollutants from entering.

[0037] The outer surface of the trousers 1 is provided with reflective strips 21. The two ends of the reflective strips 21 are fixed to the outer surface of the trousers 1 by stitching, and the reflective strips 21 are made of polyester fiber. The design of the reflective strips 21 can improve the patient's visibility at night or in low-light environments, thereby enhancing safety.

[0038] The connections and positions of the aforementioned components are all achieved through specific structural designs. For example, the flow guiding assembly 2 is connected to the trouser body 1 via the flow guiding groove 4, and the layered structure of the flow guiding cavity is achieved through partition plates. The flexible sealing strip 7 is fixed to the inner wall of the flow guiding cavity via elastic connectors, the elastic strap 10 is connected to the waist of the trouser body 1 via Velcro, and the shape memory alloy wire 11 is embedded inside the elastic strap 10 by fixing it at both ends. The absorbent core layer 13 is fixed to the inner wall of the liquid storage cavity 6 via heat-pressing points, and the temperature sensing module 17 is fixed to the outside of the antibacterial layer 3 via stitching. The connection methods between these components ensure the stability and functionality of the entire device.

[0039] The working principle of this utility model is as follows. When the patient wears the catheterization pants, the elastic tightening ring 15 and elastic cuff of the pants 1 ensure a close fit between the pants 1 and the patient's body. The flexible sealing strip 7 in the drainage assembly 2 fits tightly against the patient's perineal area, preventing urine leakage from the entrance of the drainage cavity. Urine enters the reservoir cavity 6 through the drainage channel 5, and the guide plate 12 in the drainage channel 5 guides the flow of urine and reduces residue. The absorbent core layer 13 in the reservoir cavity 6 quickly absorbs and locks in the urine, and the waterproof membrane 14 prevents urine from seeping outside the pants 1. The design of the vent 20 allows gas to be discharged from the drainage cavity, while the filter and dust cover prevent external contaminants from entering. The nano-silver fibers in the antibacterial layer 3 inhibit bacterial growth, and the breathable membrane 9 allows air circulation, thereby improving patient comfort. The temperature sensing module 17 monitors the temperature changes of the antibacterial layer 3 in real time and displays them on the display screen 18 to help medical staff understand the patient's health status.

[0040] The specific embodiments of this utility model fully disclose the technical solution, enabling those skilled in the art to implement the technology based on the contents of the specification. The connection relationships, positional relationships, and mutual cooperation relationships between the various components are described in detail, ensuring the functionality and stability of the entire device.

[0041] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.

[0042] When wearing this medical catheterization pants, the patient first puts the pants 1 over their lower body, ensuring it fits snugly against the waist via the elastic tightening ring 15. The internal spiral spring of the elastic tightening ring 15 automatically adjusts the tightness according to the patient's waistline, while the anti-slip texture of the silicone pad 16 ensures that the pants 1 will not shift or loosen during activity. Simultaneously, the elastic cuffs at the leg openings of the pants 1, through the action of tension springs, further prevent the pants 1 from shifting upwards or twisting when the patient walks or turns over.

[0043] The design of the drainage component 2 plays a crucial role during urination. The arc-shaped protrusion of the flexible sealing strip 7 fits snugly against the patient's perineal area, and its two sides are fixed to the inner wall of the drainage cavity by elastic connectors, maintaining a stable fit during patient movement and preventing urine leakage from the inlet. When urine enters the drainage channel 5, the arc-shaped structure of the drainage plate 12 and the hydrophobic coating work together to guide the urine to flow rapidly along the arc-shaped protrusion, reducing the amount of urine residue in the drainage channel 5. This structural design not only improves the urine drainage efficiency but also reduces the risk of bacterial growth due to urine retention.

[0044] The absorbent core layer 13 in the reservoir 6 is made of superabsorbent polymer (SAP). When urine flows into the reservoir 6, the absorbent core layer 13 quickly absorbs and locks in the urine, forming a gel-like substance to prevent backflow. A waterproof membrane 14 wraps around the absorbent core layer 13, effectively preventing urine from seeping to the outside of the trouser body 1, thus achieving a double leak-proof effect. Furthermore, the drain port 8 at the bottom of the reservoir 6 is sealed with a threaded cap, facilitating regular cleaning of the urine in the reservoir 6 by medical personnel, ensuring the long-term performance of the device.

[0045] The antibacterial layer 3 is woven from nano-silver fibers, effectively inhibiting bacterial growth. The breathable membrane 9 allows airflow while preventing external pollutants from entering, ensuring the patient's skin remains dry and comfortable. The temperature sensing module 17 monitors the temperature changes of the antibacterial layer 3 in real time via a temperature sensor, transmitting the data to a microprocessor for processing, and finally displaying it on the display screen 18. This design helps healthcare professionals understand the working status of the antibacterial layer 3 and changes in the patient's local body temperature, thereby assessing the risk of infection.

[0046] The vent 20 at the rear end of the drainage chamber plays a crucial role in the urine drainage process. When urine enters the drainage chamber, the gas inside is expelled through the vent 20. The filter and dust cover design prevent external contaminants from entering the drainage chamber, ensuring the cleanliness of the drainage system. The protective cover 19 at the front end of the drainage chamber protects critical components with a cushioning pad, preventing damage from external impacts. The handle design allows medical staff to quickly operate the drainage chamber when needed.

[0047] The reflective strips 21 on the outer surface of the trousers 1 enhance patient visibility at night or in low-light environments, thereby improving safety. The elastic band 10, through the properties of the shape memory alloy wire 11, can automatically adjust its tightness according to the patient's body shape, ensuring that the drainage cavity always remains in close contact with the patient's body, preventing displacement or loosening due to movement.

[0048] The aforementioned steps and the coordination between components ensure the functionality and stability of the entire device. For example, the flow guiding assembly 2 is connected to the trouser body 1 through the flow guiding groove 4, the flexible sealing strip 7 is fixed to the inner wall of the flow guiding cavity through the elastic connector, and the water-absorbing core layer 13 is firmly connected to the inner wall of the liquid storage cavity 6 through the hot-pressing point. These designs have been repeatedly verified to ensure that the connection between each component is reliable and durable.

[0049] The above content details the specific operating principle and implementation method of this utility model in practical applications, enabling those skilled in the art to implement the technical solution based on the description. The connection relationships, positional relationships, and mutual cooperation relationships between the various components have been fully explained, ensuring the functionality and stability of the entire device.
