Abstract
The utility model discloses a thoracic cavity puncture device, relating to the technical field of medical devices for department of cardiac surgery. The thoracic cavity puncture device comprises a needle head, a syringe is connected on a needle handle of the needle head by a communicating pipe, a tee joint is arranged on the communicating pipe between the needle head and the syringe; the tee joint is respectively connected with the needle head, the syringe and an output pipe; the output pipe is communicated with a drainage bag with a plug cock type valve at the bottom end, and roller type infusion regulators are arranged on the communicating pipe between the needle head and the tee joint and the output pipe between the drainage bag and the tee joint, so as to achieve the purpose of diverting tissue fluid. As the tee joint is arranged on the communicating pipe between the needle head and the syringe, and the tee joint is respectively connected with the needle head, the syringe and the output pipe, tissue fluid blood clots can be prevented from blocking the pipeline when thoracic cavity puncture is carried out, the pain of patients is alleviated and resource waste can be reduced simultaneously.
Description
Technical field
This utility model relates to the department of cardiac surgery technical field of medical instruments, relates in particular to a kind of thoracentesis device.
Background technology
Traditional thoracentesis device of past mainly contains puncture needle, drain pipe clamp, vascular forceps composition.Its shortcoming is a thoracentesis inconvenient operation, loaded down with trivial details, the inserting needle depth easily takes place in the operating process to be difficult to grasp, the easy damaged lungs cause bleeding or pneumothorax, and in the drawing liquid process, easily leak gas, air inlet, even more serious is the hydrothorax such as the random discharging of extracting out, very easily causes environmental pollution and cross infection.There is the people that existing thoracentesis device is improved for this reason, design by Chai Shoudong in JIUYUE in 2006 20 days is disclosed as State Intellectual Property Office, the patent No. is 200520086654.7, name is called the utility model patent of disposable thoracentesis device, it comprises syringe needle, syringe is by on the needle handle that is connected syringe needle communicating pipe, on the communicating pipe between syringe needle and the syringe, be provided with three-way valve, this three-way valve connects syringe needle respectively, syringe, outlet tube, outlet tube is communicated with the drainage bag of bottom band plug valve, and the communicating pipe between syringe needle and the three-way valve is provided with the roller type infusion regulator.Its shortcoming is to use the three-way valve shunting that hydrops, congestion etc. are condensed in three-way valve, cause the obstruction of three-way valve, and the manufacturing cost of three-way valve is higher.
Summary of the invention
The purpose of this utility model provides a kind of safe in utilization, convenient and low thoracentesis device of cost.
The technical scheme that this utility model is adopted for achieving the above object is:
A kind of thoracentesis device, comprise that syringe needle, syringe are by on the needle handle that is connected syringe needle communicating pipe, on the communicating pipe between syringe needle and the syringe, be provided with threeway, this threeway connects syringe needle, syringe, outlet tube respectively, outlet tube is communicated with the drainage bag of bottom band plug valve, communicating pipe between syringe needle and the threeway is provided with the roller type infusion regulator, it is characterized in that: the outlet tube between described drainage bag and the threeway is provided with the roller type infusion regulator.
A kind of thoracentesis device of the present utility model, go up the communicating pipe between syringe needle and the threeway and drainage bag and threeway between outlet tube be provided with the roller type infusion regulator, can reach the purpose of tissue fluid shunting.On the communicating pipe between syringe needle and the syringe, be provided with threeway, this threeway connects syringe needle, syringe, outlet tube respectively, can when carrying out thoracentesis, prevent blocking pipes such as tissue fluid clot, alleviate patient's misery, also reduce the waste of resource simultaneously.
