Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

First embodiment

Referring to fig. 1-4, in an embodiment of the present invention, a novel needle for thoracentesis includes: a tee joint 1;

the sleeve 2 is fixedly arranged on the tee joint 1;

the needle head is movably arranged in the tee joint 1 and the sleeve 2 and comprises a needle body 3 and a first needle seat 4, a nipple 41 is arranged at the top of the first needle seat 4, the needle body 3 is fixedly arranged on the nipple 41, the needle body 3 is a common long needle, and the nipple 41 has the same structure as that of a syringe nipple (liquid outlet pipe) and is used for firmly fixing a second needle seat 6 on the first needle seat;

the sealing ring 5 is fixedly arranged in the tee joint 1, the needle body 3 penetrates through the sealing ring 5, the sealing ring 5 mainly plays a role in sealing, after the needle body 3 enters the sleeve 2, the inner ring of the sealing ring 5 tightly wraps the needle body 3, and the outer ring of the sealing ring 5 is tightly attached to the inner wall of the tee joint 1, so that the situation that air enters the tee joint 1 and enters the lung to cause iatrogenic pneumothorax is avoided;

the second needle seat 6 is arranged on the tee joint 1, and the second needle seat 6 is matched with the first needle seat 4;

the three side holes 7 are formed in the sleeve 2, and the three side holes 7 are arranged, so that the blockage situation can not occur during liquid drainage;
