Problems solved by technology

[0003] However, the current negative pressure ball is manually pressed. During the operation, the medical staff not only need to operate the surgical site, but also need to press the negative pressure ball, which increases the workload of the medical staff and makes the operation very troublesome.
[0004] In addition, the secretion sucked into the drainage bag may flow back into the patient through the drainage tube, which may easily cause wound infection

Abstract

The invention relates to the field of medical instruments, in particular to an anti-reflux drainage device which comprises drainage bags and drainage tubes connected to the drainage bags, wherein an elastic negative-pressure ball is connected to the drainage bags; the anti-reflux drainage device further comprises a cam and a motor used for driving the cam to rotate, a protruding part used for intermittently extruding the negative-pressure ball is arranged on the cam, the negative-pressure ball is sleeved with a limiting shell, an air outlet is formed in the negative-pressure ball, a first one-way valve used for enabling air to be exhausted from the negative-pressure ball in a one-way mode is arranged on the air outlet, and second one-way valves used for enabling the air in the drainage bags to enter the negative-pressure ball in a one-way mode are arranged between the negative-pressure ball and the drainage bags. According to the scheme, automatic pressing of the negative-pressure ballis achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-reflux drainage device. Background technique [0002] During the operation on the patient, it is often necessary to excrete secretions such as blood and body fluids in the patient's body through drainage. At present, a drainage device is used to discharge the secretions in the patient's body. The existing drainage device includes a drainage bag and a drainage tube. The drainage tube is connected to the drainage bag, and the drainage bag is connected with a negative pressure ball. The negative pressure ball will suck out the gas in the drainage bag, so that the negative pressure will be generated in the drainage bag, so that the patient's secretions can be sucked into the drainage bag through the drainage tube. [0003] However, the current negative pressure ball is manually pressed. During the operation, the medical staff not only need to operate the surgical site, but als...
