AI Technical Summary
Technical Problem
When used in the existing pleural effusion drainage device, the effusion rate is too fast, resulting in increased discomfort and tension in the patient, and the drainage effect is unbalanced.
Method used
A pleural effusion drainage device for severe patients based on changes in drainage is designed. Through the combination of drainage tube group, negative pressure forming mechanism and follow-up mechanism, the automatic adjustment of the drainage path is achieved, and the flow rate change of effusion in the drainage path is gradually reduced.
Benefits of technology
Automatic adjustment of drainage volume is achieved, reducing the patient's discomfort and tension, and ensuring the easing and effectiveness of the drainage process.

Abstract
The invention relates to the technical field of medical equipment, in particular to a critical patient pleural effusion drainage device and method.The critical patient pleural effusion drainage device based on the drainage amount change comprises a box body and a liquid collecting cylinder arranged on the side portion of the box body through an elastic bearing mechanism, and further comprises a drainage pipe set and a drainage pipe, comprising a first catheter, a second catheter and a third catheter which are installed on the box body, the first catheter is connected with the second catheter through a conduction control mechanism, and the end, away from the second catheter, of the first catheter is connected with a drainage needle tube; the liquid collecting cylinder is provided with two through openings matched with the second catheter and the third catheter respectively so as to form a drainage channel of pleural effusion, finally, the function of automatically adjusting and changing the drainage amount is achieved, the whole drainage process is milder, discomfort and tension of a patient can be effectively reduced, and the drainage device is suitable for being used and popularized.
