Negative pressure diverter

Abstract

The invention discloses a negative pressure diverter, which comprises a casing, a rotary vane, and a motor, the motor is installed inside the casing, and a driving tooth is arranged at the front end, and the driving tooth meshes with the driven tooth; the casing The end is provided with an interface, which matches the liquid channel, and a motor connector, which is used for connecting an external power supply to the motor; an expansion foam installed in the anti-backflow port; and a one-way valve. The invention has reasonable design, simple and compact structure, and can easily and quickly stir and drain the liquid that may be solidified; the casing of the invention is equipped with a liquid accumulation bag, and the negative pressure pumping device is used to pump the liquid accumulation bag into a negative pressure state. The interface is connected to the waste blood vessel, and the waste blood is drained into the waste blood vessel by suction generated by negative pressure. At the same time, the rationally designed rotating blade is used for stirring to help the circulation of the waste blood. Efficiency, reduced operation time, reduced operation risk, suitable for large-scale promotion and use.

Description

technical field [0001] The invention relates to a medical device, in particular to a negative pressure drainage device used for waste liquid treatment in operations. Background technique [0002] The hospital is a medical institution with the main purpose of providing medical care services to people. It can help the recipient patients relieve their pain, but only with the advanced and convenient hospital equipment can the patient's pain be better reduced; when performing surgery in the hospital, the operating room Advanced equipment can often give medical staff higher work efficiency, shorten operation time, and at the same time reduce the pain of patients. [0003] For example: when a doctor performs an operation, there will be granular muscle tissue and bleeding at the incision, and many of them will use some liquid to wash the patient's wound, so bloody sewage will be produced; and the treatment of these bloody sewage is through In this process, the port of the negative ...

Problems solved by technology

[0003] For example: when a doctor performs an operation, there will be granular muscle tissue and bleeding at the incision, and many of them will use some liquid to wash the patient's wound, so bloody sewage will be produced; and the treatment of these bloody sewage is through In this process, the port of the negative pressure device is easily blocked, and when the negative pressure device is not used for a period of time, the bloody sewage is easy to coagulate, and it is easy to block the catheter and the negative pressure device It is very inconvenient for medical staff to use it, which will cause catheter blockage, prolong operation time and increase operation risk
