Negative pressure flusher

Abstract

The invention belongs to the field of portable medical instruments, particularly provides a medical instrument capable of achieving negative pressure flushing, and relates to a negative pressure flusher. The negative pressure flusher aims to solve the problem that an existing flusher cannot flush a guide pipe smoothly when blocky materials are mixed in flowing liquid. The negative pressure flusher comprises a syringe, a piston arranged in the syringe, a piston rod connected to the piston from one side and a breaking component connected to the piston from the other side. A connector is arranged on the syringe and can be connected with a guide pipe. When the syringe is full of flushing liquid, the piston rod is pushed, the guide pipe is flushed by the flushing liquid, and meanwhile a breaking device smashes blocky secreta flowing in the guide pipe; and in addition, the negative pressure flusher can be used in cooperation with a flushing bag and a drainage bag, repeated flushing on the guide pipe is achieved, the flushing effect of the negative pressure flusher is improved, and a good dredging function is achieved on the guide pipe.

Description

technical field [0001] The invention belongs to the field of medical equipment, and specifically provides a negative pressure flusher for urinary catheters. Background technique [0002] With the increasingly harsh living environment, the prevalence rate of human beings is also increasing year by year. Especially in recent years, more and more patients need surgical treatment every year to recover, but many patients still exist after surgical treatment. Many postoperative problems, for example, patients in the Department of Urology need to use a catheter to remove the substances in the bladder after undergoing urinary tumor resection or vascular disease surgery. There is still residual tissue in the urine, and the clot and residual tissue in the discharge often lead to poor drainage of the catheter, or even blockage. [0003] In order to remove blood clots and residual tissue blocks and make the drainage of the urinary catheter unobstructed, at present, medical personnel us...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the existing syringe or lavage device cannot dredge the urinary catheter well, the present invention provides a negative pressure washer, which is connected with the catheter , for sucking the massive secretion of the human organ to which the catheter is connected, characterized in that the negative pressure washer comprises a syringe, a piston arranged in the syringe, connected to the The piston rod of the piston and the crushing member connected to the piston from the other side, during use, the syringe is connected to the catheter, the crushing member protrudes from the syringe and extends to the In the catheter, when the piston rod reciprocates in the syringe, the crushing member can crush the lumpy secretion in the catheter
