Liquid drainage control system, and liquid collection bag and pressure monitoring unit thereof, connected with pressure monitoring and controlling unit

Abstract

The invention provides a liquid drainage control system, and a liquid collection bag and a pressure monitoring unit thereof, connected with a pressure monitoring and controlling unit. The liquid drainage control system comprises an electronic control unit, the pressure monitoring and controlling unit, the liquid collection bag and a liquid pipeline, wherein the pressure monitoring and controlling unit comprises a control valve and a pressure sensing component, the pressure sensing component can be used for monitoring liquid pressure and outputting pressure signals, the control valve controls the connection and the disconnection between a liquid inlet and a liquid outlet according pressure signals; the liquid inlet of the pressure monitoring and controlling unit is communicated with a pipe inserted into a human body, the liquid outlet is communicated with the liquid collection bag through the liquid pipe, the function of helping a patient to drain is achieved, and more risks during use by the patient are effectively avoided.

Description

technical field [0001] The invention relates to a liquid drainage control system, a liquid collection bag connected to a pressure monitoring control unit, and a pressure monitoring control unit, which are mainly used for the drainage control and collection of human body fluid, and belong to the technical field of medical devices. Background technique [0002] There are many types of surgical drainage tubes used clinically, and they are used in the chest cavity, brain cavity, gastrointestinal tract, biliary tract, and bladder. The purpose of surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or body cavities to the outside of the body, to prevent postoperative infection and affect wound healing, and to prevent organ damage in coma, urinary incontinence, and postoperative states. For example, many patients with paraplegia and hemiplegia caused by cerebrovascular and spinal cord vascular diseases, most of them are accompanied by urination ...
