Precharged negative pressure drainage device

Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a precharged negative pressure drainage device. The precharged negative pressure drainage device ischaracterized in that a drainage tube is inserted into the outer wall of the top of a drainage bottle, a transition tube is in threaded connection with the end, away from the drainage bottle, of the drainage tube, a sealing regulation valve is in threaded connection with the end, away from the drainage tube, of the transition tube, a Luer taper is in threaded connection with the end, away from thetransition tube, of the sealing regulation valve, a connecting tube is in threaded connection with the end, away from the sealing regulation valve, of the Luer taper, a tower joint is in threaded connection with the end, away from the Luer taper, of the connecting tube and suitable for different types of drainage tubes, a through hole is formed in one side of the outer wall of the top of the drainage tube, and a one-way valve is inserted into the through hole. The precharged negative pressure drainage device has beneficial effects as follows: by means of the sealing regulation valve, a doctorcan adjust negative pressure according to the drainage part of a patient while the sealing performance is better, and therefore, the device can be suitable for clinical complex environments.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pre-filled negative pressure drainage device. Background technique [0002] The negative pressure suction device is a tool that creates the negative pressure state of its suction head through a certain method, and the material outside the suction head is squeezed toward the suction head to complete the "suction" effect. [0003] Chinese Patent No. CN103638590B provides a negative pressure drainage device, which includes a drainage ball and a drainage tube connected to the drainage ball, and is characterized in that a filter is provided in the drainage tube, and a spike is provided on the filter. The invention has the advantages of simple structure and convenient use, can make the drainage material quickly enter the drainage ball, and the drainage tube is not easy to be blocked, thereby reducing the labor of medical personnel while alleviating the pain of the patient. ...
