Abstract
The utility model relates to a thoracic puncture and drainage device which belongs to the technical field of the medical device. The thoracic puncture and drainage device consists of a syringe, a drainage tube, and a puncture syringe needle; the thoracic puncture and drainage device is characterized in that a unidirectional liquid inlet valve is arranged in the middle of a liquid inlet tube in front of the syringe; the outer wall of the front end of the liquid inlet tube is provided with a ring-shaped embossment; the side wall of the front end of the syringe is provided with a liquid outlet tube communicated with the inner cavity of a syringe cylinder; and the unidirectional liquid inlet valve is arranged on the liquid outlet tube; one end of the drainage tube is connected with the puncture syringe needle, the outer wall of which is provided with scale marks, and the other end of the drainage tube is sleeved on the ring-shaped embossment at the front end of the syringe. The utility model has simple structure, convenient use, and continuous push and pull in a sealed environment, can avoid the position change of the puncture syringe needle resulted from the repeat clamping of hemostatic forceps and the repeat extraction of the syringe and can prevent pneumothorax.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of thoracic drainage and thoracentesis device.
Background technology
At present, when hydrothorax is taken out in capable puncture to hydrothorax, generally with traditional thoracentesis needle, close the flexible pipe that is connected with piercing needle with mosquito forceps after extracting a syringe hydrothorax out, to prevent that gas from entering the thoracic cavity and causing pneumothorax, pull out being connected of syringe and flexible pipe, be connected with syringe again after turning down hydrothorax, unclamp mosquito forceps, carry out the suction second time, and the like, again and again, in aspiration procedure,, closes mosquito forceps owing to pressing from both sides repeatedly, unclamp, syringe is connected repeatedly with flexible pipe, disconnect, the position of piercing needle is changed and injure lungs, and action cooperates and badly air backflowed cause pneumothorax into the thoracic cavity.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy to operate, but continuous sucking, accurately metering, the thoracic drainage and thoracentesis device that suction is carried out under enclosed environment all the time.
The purpose of this utility model is achieved in that this thoracic drainage and thoracentesis device is made up of syringe, drainage tube, piercing needle, syringe front end feed tube middle part is provided with unidirectional feed liquor valve, feed tube front end outer wall is provided with annular protrusion, the syringe front end side wall is provided with the drain pipe that communicates with the syringe inner chamber, and drain pipe is provided with unidirectional liquid valve; Drainage tube one end is connected with the piercing needle that outer wall is provided with scale mark, and the other end is sleeved on the annular protrusion of syringe front end feed tube.
Advantage of the present utility model: simple in structure, easy to operate, but continuous sucking, accurately metering, suction is carried out under enclosed environment all the time, avoid because of mosquito forceps repeatedly clamp and syringe extract repeatedly and cause the position of puncture needle to change, prevent to cause pneumothorax.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
