Body-cavity effusion drainage system

Abstract

The invention discloses a body-cavity effusion drainage system. The body-cavity effusion drainage system includes a control module, an electric air exhaust pump, a sealed liquid storage tank, an air-pressure detecting module, an effusion catheter and a valve, the electric air exhaust pump is provided with an air suction port which is communicated with the interior of the sealed liquid storage tank through an air catheter, the air-pressure detecting module is arranged in the sealed liquid storage tank, one end of the effusion catheter is communicated with the interior of the sealed liquid storage tank, the valve is arranged on the effusion catheter, the control module includes a controller and a display module which is connected with the controller, the controller is in signal connection with the air-pressure detecting module, is connected with the electric air exhaust pump and controls the electric air exhaust pump, and a battery provides power for the controller. According to the body-cavity effusion drainage system, through the air-pressure detecting module, the air pressure in the sealed liquid storage tank is detected, and information is sent to the controller; through the controller, the electric air exhaust pump is controlled to work, so that the air pressure in the sealed liquid storage tank reaches a preset value, in this way, the pressure is controlled, and the situation is avoided that the gastrointestinal mucous membrane of the human body is damaged when body-cavity effusion drainage is conducted.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a body cavity fluid drainage system. Background technique [0002] Extracting body cavity fluid through negative pressure drainage is a common method for clinical diagnosis and treatment, but there are many problems in negative pressure drainage, especially when extracting gastric juice, because the pressure is not easy to control, it may cause damage to the gastrointestinal mucosa of the human body . [0003] Chinese invention patent "Body Cavity Fluid Drainage System" (publication number: 106512112A; publication date: March 22, 2017) discloses a body cavity fluid drainage system, which includes a drainage tube, a connection with the drainage tube An extension tube connected at one end, a negative pressure drainage device connected with the extension tube, and a puncture device is pierced on the other end of the drainage tube; wherein, the negative pressure ...

[0002] Extracting body cavity fluid through negative pressure drainage is a common method for clinical diagnosis and treatment, but there are many problems in negative pressure drainage, especially when extracting gastric juice, because the pressure is not easy to control, it may cause damage to the gastrointestinal mucosa of the human body

[0003] Chinese invention patent "Body Cavity Fluid Drainage System" (publication number: 106512112A; publication date: March 22, 2017) discloses a body cavity fluid drainage system, which includes a drainage tube, a connection with the drainage tube An extension tube connected at one end, a negative pressure drainage device connected with the extension tube, and a puncture device is pierced on the other end of the drainage tube; wherein, the negative pressure drainage device is cylindrical, and there is a The upper end of the spring is provided with the first opening connected by the extension tube; through analysis, it can be seen that the volume of the negative pressure drainage device is compressed by pressing the spring, thereby driving out the air inside the negative pressure drainage device, and the spring is released to restore it to its original state, negative pressure. The pressure drainage device returns to its original state. At this time, a negative pressure is formed inside the negative pressure drainage device. It may cause excessive pressure difference and cause damage to the gastrointestinal mucosa of the human body
