Air-pressure-type drainage controller

Abstract

The invention discloses an air-pressure-type drainage controller. The controller comprises a hollow cylindrical flow limit annular sleeve, an elastic extrusion layer is sleeved with the flow limit annular sleeve, and an airbag is defined between the elastic extrusion layer and the flow limit annular sleeve. A control unit controls the pressure of the airbag and controls the drainage process. The air-pressure-type drainage controller is high in automation level and flexibility and provides more safety guarantee for drainage.

Description

technical field [0001] The invention relates to the technical field of medical mechanical equipment, in particular to a pneumatic drainage controller. Background technique [0002] When draining internal fluids to the outside of the body in critically ill patients, it is usually necessary to quantify the parameters in the drainage process (such as drainage rate, drainage fluid volume, etc.) to ensure safe drainage as much as possible. In the process of traditional medical drainage, medical staff need to check and observe in real time, summarize and judge the outflow of drainage fluid, and further judge the solution content in the body and the recovery status of the patient. However, this drainage method requires high experience of medical staff and cannot be objective and timely. Actions to be taken in case of drainage parameters. [0003] On the other hand, during drainage, medical staff often need to observe the drainage situation frequently. Under the current situation t...

Problems solved by technology

In the process of traditional medical drainage, medical staff need to check and observe in real time, summarize and judge the outflow of drainage fluid, and further judge the solution content in the body and the recovery status of the patient. However, this drainage method requires high experience of medical staff and cannot be objective and timely. Measures to be taken in case of drainage parameters

[0003] On the other hand, during drainage, medical staff often need to observe the drainage situation frequently. Under the current situation that one medical staff needs to monitor multiple patients at the same time, sometimes it will cause more unfavorable problems to patients because the patients are not monitored in time and necessary measures are taken. As a result, even endanger the life and health of patients
