Abdominal-cavity drainage device

Abstract

The invention discloses an abdominal-cavity drainage device. The device includes a main machine, a collection box, a shunt pipe and a drainage pipe; the shunt pipe includes a backflow pipe and a pressure pipe, the head end of the backflow pipe is provided with a shunt-pipe joint, the head end of the pressure pipe is communicated with the head end of the backflow pipe through a pressure branch pipe, and the tail end of the backflow pipe and the tail end of the pressure pipe are provided with a backflow interface and a pressure interface respectively; the collection box is provided with a backflow-pipe interface and a negative-pressure interface; an electromagnetic valve, a first pressure sensor, a second pressure sensor and a negative-pressure pump are arranged in the main machine, and the side wall of the main machine is provided with a main-machine pressure interface and a main-machine negative-pressure interface; the main-machine negative-pressure interface is communicated with the electromagnetic valve and the first pressure sensor through flexible pipes; the main-machine negative-pressure interface is communicated with the second pressure sensor and the negative-pressure pump through flexible pipes. By the adoption of the abdominal-cavity drainage device, the pressure can be accurately controlled, and the abdominal-cavity drainage device is conductive to improving the efficiency and quality of drainage.

Description

technical field [0001] The invention relates to a medical device, in particular to a negative pressure drainage device. Background technique [0002] In the medical field, it is necessary to use a drainage device to extract excess fluid from the patient's chest cavity or abdominal cavity under negative pressure. The structure of the abdominal cavity drainage device in the prior art is relatively complicated. During the drainage process, due to the design of the drainage circuit, the control of the negative pressure is difficult. It is not accurate enough, and the drainage tube is often blocked by human tissue. If necessary, the drainage tube needs to be replaced for re-drainage, which is time-consuming and laborious, and also increases the pain of the patient. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an abdominal cavity drainage device with reasonable pipeline design and precise pressure contr...
