AI Technical Summary
Existing urine collection containers are prone to deformation during use and cannot fit tightly to the body, leading to urine backflow and leakage. This is especially problematic when the patient is weak, as it can easily scratch the skin and cause infection.
Design a flexible connection device using a curved, horn-shaped hollow tube made of silicone, TPR elastomer, or PE to ensure that the urination port remains drooping under gravity, preventing urine backflow and increasing capacity to buffer urine flow.
It effectively prevents urine backflow and leakage, reduces the risk of skin abrasions, and improves patient comfort and safety.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical and health care products, and in particular relates to a connection device for preventing urine backflow and overflow suitable for patients. Background Technology
[0002] Currently available urine collection containers are all fixed in shape and lack flexibility, designed under ideal conditions. They are prone to deformation and cannot be restored, causing urine leakage. Everyone's sleeping position and usage scenario are different, and frequent changes in posture cause the angle of the urine collection container to change. However, during use, the rigid material of the urine-discharging part cannot completely conform to the body. Furthermore, patients are often weak, and the urine flow is slow and weak during urination, leading to urine backflow and leakage, which can easily cause skin abrasions and infections. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides a connecting device for preventing urine backflow and overflow. One side of the connecting device is connected to a urine collection container, and the other side of the connecting device is connected to a urination port. The connecting device is a hollow pipe, so that urine in the urine collection container passes through the connecting device and is discharged through the urination port. The connecting device is malleable, so that the urination port always remains in a drooping state under the action of gravity.
[0004] The connecting device is a curved horn shape, with the outer arc length being greater than the inner arc length.
[0005] The connecting device has a larger opening on the side connected to the urine collection container and a smaller opening on the side connected to the urination port.
[0006] The connecting device is circular or elliptical on the side that connects to the urine container.
[0007] The connecting device is circular on the side that connects to the urination port.
[0008] The connecting device is made of silicone, TPR elastomer or PE.
[0009] The thickness of the connecting device is 1-2 mm.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This invention uses a soft, harmless silicone, TPR elastomer, or PE material for the connecting device. Regardless of the angle of the urine collection container, the outlet of the container always remains naturally drooping at a low position under the influence of gravity, thus preventing urine backflow and spillage. It also increases the capacity of the urine collection container, providing a buffer for patients with high urine flow and preventing spillage. The connecting device features a curved, flared design, ensuring minimal contact with the skin and preventing damage, further protecting patient safety. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings:
[0017] like Figures 1-4 As shown, this utility model provides a connecting device for preventing urine backflow and overflow. The connecting device 1 is part of a urination device, with one side connected to a urine collection container 2 and the other side connected to a urination outlet 3. The urine collection container 2 is shaped like a waist drum and is used to collect urine. The urination outlet 3 is located at the lower part of the urine collection container 2 and is used to drain urine. The connecting device 1 is a hollow pipe located between the urine collection container 2 and the urination outlet 3. This allows urine in the urine collection container 2 to pass through the connecting device 1 and then be discharged through the urination outlet 3. The connecting device 1 increases the capacity of the urine collection container 2, alleviating the problem of short-term urine storage. The connecting device 1 is malleable, allowing the urination outlet to remain in a drooping state under gravity, thus preventing urine backflow and overflow.
[0018] like Figures 1-3As shown, the connecting device 1 is a curved trumpet shape, with its outer arc length 11 being greater than its inner arc length 12, to ensure that the connecting device 1 has a good curvature and fits snugly against human skin. The opening of the connecting device 1 on the side connected to the urine container 2 is large, while the opening on the side connected to the urination port 3 is small. The small opening on the discharge side allows for a fast urine flow, which is beneficial for the smooth flow of urine from the urination port 3. The thickness of the connecting device 1 is 1-2 mm, which ensures the strength of the connecting device 1 and prevents it from breaking under the impact of urine. In this embodiment, the thickness of the connecting device 1 is 1.5 mm. The side of the connecting device 1 connected to the urine container 2 is circular or elliptical. In this embodiment, the side of the connecting device 1 connected to the urine container 2 is elliptical 13. The side of the connecting device 1 connected to the urination port 3 is circular 14. The connecting device 1 can be connected to the urine container 2 and the urination port 3 by various methods such as adhesive bonding and heat fusion bonding.
[0019] The connecting device 1 is made of a flexible material, specifically silicone, TPR elastomer, or PE. Silicone is softer and non-irritating to the skin; TPR elastomer is a thermoplastic rubber, and its performance is superior to silicone, providing greater comfort. Furthermore, connecting devices made of silicone, TPR elastomer, or PE are easier to mold and clean. Regardless of the angle of the urine collection container, the urination port remains naturally drooping at a low position under gravity, effectively preventing urine backflow and spillage. Moreover, the connecting device features a curved, flared design, ensuring minimal skin contact and preventing skin damage, further guaranteeing patient safety.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
