Pneumothorax puncture needle

Abstract

The invention discloses a pneumothorax puncture needle, which comprises a needle core (1) and a sleeve (2), the needle core (1) is inserted into the sleeve (2), and the front end extends out of the sleeve (2); drainage is also provided The one-way valve (4), the front section and the rear section of the casing (2) are respectively the front hard pipe section (21) and the rear hard pipe section (23), the middle section is the middle hose section (22), and the back section of the rear hard pipe section (23) When the needle core (1) is pulled out, a drainage one-way valve (4) is installed at the rear end of the rear hard pipe section (23). The end of the one-way valve is an L-shaped air guide tube (6). The trachea (6) is transparently provided with a spherical fan (7) inside; an extended hard pipe section (24) is arranged between the front hard pipe section (21) and the middle hose section (22), and the extended hard pipe section (24) and The front hard pipe section (21) is integrally formed, and the extended hard pipe section (24) is sleeved with a shielding sheath (8). The advantage of the present invention is that it can overcome the disadvantages of the prior art, and the structure design is reasonable and novel.

Description

technical field [0001] The invention relates to a pneumothorax puncture needle and belongs to the field of medical instruments. Background technique [0002] Pneumothorax puncture is one of the most commonly used diagnosis and treatment techniques in thoracic surgery. The current traditional method is to use an indwelling puncture needle to puncture, pull out the needle core, leave the cannula at the drainage site, and then connect the drainage bottle and the drainage tube through the drainage tube. Drainage with a cannula, although this method is effective, also has the defects of a large number of devices, cumbersome operation steps, and inconvenient portability, especially when the patient is facing first aid or field treatment, the above defects are more prominent. A pneumothorax puncture needle for first aid (Patent No. CN201620769395.6) is disclosed in the prior art to solve the above problems. This kind of pneumothorax puncture needle in the prior art is mainly used ...
