Medical drainage device special for cardiology department

Abstract

The invention relates to the technical field of medical treatment, and discloses a medical cardiology department special drainage device. The device comprises a shell and a needle; a round cavity is formed in the side wall of the shell, a catheter is arranged in the round cavity, the side wall of the catheter is fixedly connected with the side wall of the round cavity, and the two ends of the catheter penetrate through the side wall of the round cavity and extend outwards; a rotating block is rotatably connected to the center of the circular cavity through a rotating sleeve, two movable rods are symmetrically and fixedly connected to the side wall of the rotating block, circular blocks are fixedly connected to the ends, away from the rotating block, of the two movable rods, and the circular blocks and the guide pipe are arranged in a mutual extrusion mode; the syringe needle is fixedly communicated with the end, extending to the outside, of the catheter, the other end of the catheter is fixedly communicated with a liquid discharging pipe, one end of the rotating block penetrates through the side wall of the circular cavity and extends outwards, and a limiting mechanism is arrangedat the end, extending to the outside, of the rotating block. Concentrated water can be continuously and slowly pumped, the stability is good, and people can conveniently use the concentrated water pumping device.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a special drainage device for medical cardiology. Background technique [0002] Drainage is the act, process and method of drawing fluid from a body cavity or wound by means of attraction or gravity. [0003] At present, most of the special drainage devices for cardiology use a syringe to drain the concentrated water in the heart. When the syringe is full, the syringe needs to be taken out from the inside of the human body, and then the syringe needs to be replaced to extract the concentrated water again, which cannot be continuously extracted. Operation is cumbersome, and then is not convenient for people's use. Contents of the invention [0004] The purpose of the present invention is to solve the problem in the prior art that when the inside of the syringe is full, it is necessary to take out the syringe from the inside of the human body, and then replace the syringe to ex...
