Ascites drainage control device

Abstract

The invention relates to the field of medical instruments, and discloses an ascites drainage control device. The ascites drainage control device is composed of a folding bracket assembly, a suspensionsupporting assembly, a flow speed adjusting assembly, a controller and a power supply assembly. The folding bracket assembly adopts a folding design, can provide support for other parts, and can feedback a weight signal to the controller; the suspension supporting assembly is used for suspension supporting of a drainage bag; the flow speed adjusting assembly comprises a connecting tube used forcommunication between a drainage tube and the drainage bag, a speed adjusting mechanism used for extruding the connecting tube to different degrees to control the drainage speed and a driving device used for providing power for the speed adjusting mechanism; and the controller can control the speed adjusting mechanism based on a weight signal and preset parameters. The ascites drainage control device adopts an intelligent design, can realize automatic control of timing drainage, quantitative drainage and constant-speed drainage by cooperation with an existing conventional drainage assembly, improves the safety and stability of drainage operation, adopts a foldable design as a whole, is portable to carry and place, and is convenient and quick to operate.

Description

[0001] The present invention is a divisional application of the invention patent application with application number 2018111350238 submitted on September 28, 2018. technical field [0002] The invention relates to the technical field of medical devices, in particular to a device capable of controlling clinical ascites drainage operations. Background technique [0003] Under normal conditions, there is a small amount of fluid (generally less than 200ml) in the peritoneal cavity of the human body, which acts as a lubricant for intestinal peristalsis. If the amount of fluid in the peritoneal cavity increases under pathological conditions, when it exceeds 200ml, it is called peritoneal effusion, also known as peritoneal effusion clinically. ascites. There are many causes of peritoneal effusion, such as cardiovascular disease, liver disease, peritoneal disease, kidney disease, nutritional disorder, abdominal metastasis of malignant tumor, ovarian tumor, connective tissue disease,...

AI Technical Summary

Problems solved by technology

[0004] In the clinical operation of drainage of a large amount of effusion, there are often specific requirements for clinical parameters such as daily drainage times, each drainage volume, and drainage speed according to the condition of the case. The parameters are usually controlled subjectively by the medical staff or the patient's family members. The current artificial control method has certain disadvantages. As a result, the drainage process cannot be carried out in the way the doctor expected, and the improper drainage will cause discomfort and injury to the patient, and even endanger the patient's life. On the other hand, the real-time drainage volume and drainage speed during the drainage process are usually determined by human observation. Judgment, the error is large, and it is difficult to guarantee the drainage effect. At the same time, the current control method will obviously increase the burden on the medical staff and the patient's family members.
