Abstract

The utility model relates to a pneumothorax puncture needle, which mainly comprises a needle body (1), a union body (2), a syringe (3), a transfusion system (4) and a drainage pack (5); the ends of the union body of the tee are respectively connected with the needle body (1), the syringe (3) and the transfusion system (4); the drainage pack (5) with a drainage switch (12) is connected with the soft pipe at the other end of the transfusion system (4), wherein the needle body (1) is provided with a switch (6) of the needle body, both ends of the union body with one end connected with the needle body and the other end connected with the transfusion system are respectively provided with spherical shape switches (7, 8). The utility model has the advantages that negative-pressure is generated because of the elastic force of springs, liquid in the thoracic cavity can be sucked as well as the tip of the needle pierces into the thoracic cavity without worrying the lung pierced by the needle tip, the pneumothorax is formed, and thus, the safety is high; furthermore, for the wide range of application, and the pneumothorax puncture needle can be used for the patients who have hydrothorax, ascites, arthroedema, pneumothorax, etc. In addition, the liquid withdrown is not exposed to air and can be sterilized in the state of hermetic closure that is pollution-free for environment.

Description

Novel thoracentesis needle

Technical field

This utility model relates to medical machinery, is specifically related to a kind of novel thoracentesis needle.

Background technology

At present, for patients such as hydrothorax, arthroedema, pneumothoraxs, particularly the perforation drainage is adopted in hepatic ascites, tuberculous pleural effusion patient's treatment mostly, the one, patient is painful big, the 2nd, operation safety is not high, and easily thorn goes up lungs and forms pneumothorax, and the 3rd, operating difficulty is big, need carry out special training, the 4th, the hydrops of extracting out exposes contaminated environment in the air.

Summary of the invention

The purpose of this utility model is: a kind of novel thoracentesis needle is provided, utilizes the direct puncture drainage of this pin, simplify the operation, alleviate patient's misery, safety is provided.

Technical solution of the present utility model is: this puncture needle is mainly connected to form by needle body, union body, syringe, transfusion device and drainage bag, each end of the union body of threeway connects needle body, syringe and transfusion device respectively, and drainage bag connects on the transfusion device other end flexible pipe.

Each parts is connected to form novel thoracentesis needle, then needle point is entered to adjust corresponding each parts switch behind the subcutaneous tissue and promptly can carry out the hydrops drain.

Description of drawings

Fig. 1 is this utility model structural representation

Among the figure: 1 needle body, 2 union bodies, 3 syringes, 4 transfusion devices, 5 drainage bags, 6 needle body switches, 7,8 unidirectional ball type switch, 9 springs, 10 pintles, 11 speed control system switches, 12 drainage bag switches

The specific embodiment

As shown in the figure, this puncture needle is mainly by needle body 1, union body 2, syringe 3, transfusion device 4 and drainage bag 5 connect to form, union body 2 each end of threeway connect needle body 1 respectively, syringe 3 and transfusion device 4, the drainage bag 5 of band drain switch 12 connects on the other end flexible pipe of transfusion device 4, wherein, establish needle body switch 6 on the described needle body 1, union body is provided with unidirectional ball type switch 7 respectively with the two ends that needle body is connected with transfusion device, 8, constitute unidirectional ball type switch 7 by density near the spheroid of water, 8, its diameter is slightly less than the union body lumen diameter, the flow direction of the motor control liquid by spheroid; The speed control system switch 11 that drips of transfusion device is positioned at the flexible pipe upper end, establishes spring 9 on the pintle mouth of syringe 3 and produces the outwards power of motion of pintle that makes.

During use, operation as follows:

1, checks whether puncture needle is expired, whether intactly packs.

2, check whether leak gas

(1) except the syringe, puncture needle is connected, gas in the emptying drainage bag, and tighten the drainage bag switch.

(2) fasten transfusion device and drip speed control system switch and syringe needle switch.

(3) emptying syringe proper amount of gas and union body connect, if pintle is returned to and resets, then must reexamine connection or change puncture needle.

3, puncture: needle point enters subcutaneous tissue, opens the syringe needle switch, then, continues inserting needle, has when needle point passes parietal pleura and breaks through sense, and at this moment, liquid can be attracted owing to the suction function of syringe.

4, open the transfusion device gauge tap, the controlling liquid flow velocity in case intrathoracic pressure power is too high, causes patient's discomfort behind poly-right the decline.

5, suction: promote pintle, unidirectional ball type switch 7 closes, and unidirectional ball type switch 8 is opened, liquid flows to drainage bag from syringe, unclamp behind the pintle because the elastic force effect of spring forms negative pressure in the syringe, switch 7 leaves, and switch 8 closes, and liquid flows in the syringe from the thoracic cavity.

6, as if injectable drug in the thoracic cavity, close the syringe needle switch, keep syringe needle, pull out remaining part, the syringe that connects injection is opened the syringe needle switch, injects required medicine, and routine is pulled out syringe needle then.

The utlity model has following advantage: (1) not necessarily will realize and break through sense because the elastic force effect of spring forms negative pressure, and needle point enters the thoracic cavity can attract liquid, and worries that thorn goes up lungs, forms pneumothorax, and safety is good.(2) understandable eager to learn, one the religion promptly can, be specially adapted to begin to learn puncture person.(3) applied widely, can be used for hydrothorax, patients such as ascites, arthroedema, pneumothorax.(4) liquid of Chou Chuing is not exposed in the air, can airtightly sterilize environmentally safe.

Claims
