Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of internal medicine drainage device of thoracic cavity.
Background technology
In the internal medicine medical treatment, the Thoracicoabdominal puncture art is common diagnosis and treatment item.At present, the breast abdomen drainage device of using is connected with syringe as a section of sebific duct, the other end is connected with syringe needle, takes over by a glass between syringe needle and sebific duct to be connected, in use owing to will repeatedly sterilizing, easily cause the aging of sebific duct and stick together, gas leakage easily occurs the seam of glass adapter and puncture needle and sky is taken out phenomenon, needs to clamp sebific duct with mosquito forceps complex operation in aspiration procedure, a people is difficult to complete all operations were, has brought very large trouble to treatment.
Summary of the invention
This utility model is for the prior art above shortcomings, a kind of internal medicine drainage device of thoracic cavity is provided, design by conduction hole makes drainage effect better to this internal medicine with drainage device of thoracic cavity, the generation of effectively having avoided liquid to flow backwards by the design of drain check valve and drain check valve simultaneously.
The purpose of this utility model is to be achieved through the following technical solutions:
a kind of internal medicine drainage device of thoracic cavity, comprise syringe needle, described syringe needle is provided with conduction hole, described syringe needle end is provided with sucker, described sucker end is provided with conduit, be provided with the drain check valve in described conduit, described conduit is provided with the drain control valve, described catheter tip is provided with needle tubing, be provided with piston in described needle tubing, described needle tubing wall is provided with the needle tubing scale, be provided with drainage tube near described needle tubing place on described conduit, be provided with the drain check valve in described drainage tube, described drain check valve bottom on described drainage tube is provided with the drain control valve, described catheter tip is provided with bottle cap, described bottle cap has drainage bottle, described drainage bottle wall is provided with the drain scale.
Described conduction hole is 4-10.
This utility model beneficial effect: simple in structure, easy to use, do not backflow, syringe needle is easily fixing, and people just can complete operation, reduces doctor's labor intensity, dependable performance, drainage effect is good, is adapted at the medical appliance field and applies.
