AI Technical Summary

Technical Problem

In existing technologies, the drainage rate cannot be controlled during abdominal drainage, leading to complications such as a sudden drop in abdominal pressure, pulmonary edema, and hypotension. Furthermore, the drainage rate cannot be flexibly adjusted according to the patient's condition, affecting the treatment effect and patient comfort.

Method used

Design a speed control switch including a switch body and a speed control roller. By fitting the switch body onto the drainage tube and using the speed control roller to rotate within the accommodating cavity, the degree of squeezing on the drainage tube is gradually adjusted, thereby controlling the flow rate of the accumulated fluid.

Benefits of technology

It enables flexible control of the drainage rate, avoids complications, improves treatment effectiveness and patient comfort, and reduces pain.

Abstract

The utility model provides a speed regulation switch for peritoneal drainage. The speed regulation switch comprises a switch main body and a speed regulation roller, wherein the middle part of the switch main body is provided with a placing groove which penetrates through two ends along the axial direction and is opened on one side, and the placing groove is suitable for being clamped and fixed with a drainage tube; a containing cavity communicated with the placing groove is formed in the middle of the top of the switch body, and a long-strip-shaped opening communicated with the containing cavity is formed in the top face of the switch body; the speed regulating roller is movably mounted in the accommodating cavity and can rotate along the accommodating cavity so as to gradually increase or reduce the extrusion on the drainage tube. During use, a drainage tube is sleeved with the switch body, the speed adjusting roller is pushed to move in the containing cavity, the extrusion degree of the speed adjusting roller on the drainage tube is adjusted, and therefore the flow speed of hydrops in the drainage tube is controlled, and after drainage is finished, the switch body is taken down from the drainage tube; the speed regulating switch can be flexibly adjusted according to the drainage speed required by a patient, complications caused by improper flow speed are avoided, the treatment effect is improved, and the pain of the patient is relieved.
