AI Technical Summary

Technical Problem

Existing urethrostomy instruments have valves that are inconvenient to operate, making it difficult to open and close them easily without repositioning both hands, and are prone to unwanted dripping or overflow.

Method used

A valve comprising a first valve section and a second valve section is designed, which is threadedly engaged by a threaded connector, allowing the sleeve to rotate relative to the handle to open and close the passage, and the distal closure is adapted to close or open the valve outlet to achieve controlled discharge of fluid.

Benefits of technology

It provides an easy-to-use valve that users can easily open and close by rotating the sleeve to control the flow rate and prevent unwanted dripping or overflow, making it suitable for the ergonomic needs of most users.

Abstract

A valve (10) for draining fluid from a urostomy pouch (5), wherein the valve (10) comprises a first valve part (20) and a second valve part (30), the first valve part comprising a head part (24), an inlet (15), a stem (6), a first bore (22), at least one outlet opening (23) and a distal closure (25), the second valve part comprising a sleeve (7), a second bore (32) and a valve outlet (33), wherein the stem (6) and the sleeve (7) are threadably engaged by a threaded connection (26), the first bore (22) and the second bore (32) form a passage to convey fluid from the inlet (15) to the valve outlet (33), the sleeve (7) surrounds the stem (6) and is adapted to close the passage to prevent fluid drainage, the distal closure (25) of the first valve part (20) is adapted to close the valve outlet (33) of the second valve part (30), the threaded connection (26) between the stem (6) and the sleeve (7) is adapted to displace the sleeve (7) away from the head part (24) of the first valve part (20) to open the passage and allow fluid drainage through the valve (10) as the distal closure (25) is simultaneously displaced into the second bore (32).
