Abstract

The invention discloses a double-channel thoracentesis needle, which comprises a main pipeline, a needle tube, a needle stretching device, an outer needle head, an inner needle head, a blocking deviceand a lateral passing pipeline, wherein the needle tube is connected with the main pipeline and the lateral passing pipeline; one end of the needle tube is connected with the outer needle head; the outer needle head is opposite to the main pipeline; the inner needle head is arranged inside the outer needle head; one end of the inner needle head is arranged in the needle tube; the needle stretching device and the blocking device are arranged on the side wall of the needle tube; the needle stretching device is connected with one end of the inner needle head; and the blocking device is matched with the inner needle head. After the double-channel thoracentesis needle is inserted into the thoracic cavity, the inner needle head is pushed out through the needle stretching device, so that the thoracentesis needle is convenient to use; in the insertion process, the use of the outer needle head cannot be affected; the blocking device is matched with the inner needle head, so that the inner needle head can be blocked by the blocking device to facilitate insertion and drawing of an injector; the problem of inconvenience of inserting and drawing the injector of an existing thoracentesis needleis solved; and the use safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-channel thoracentesis needle. Background technique [0002] Thoracentesis is a method commonly used in clinical diagnosis and treatment of diseases. If a patient is found to have fluid in the pleural cavity, the fluid can be extracted through thoracentesis, and various tests can be performed to find the cause of the disease; if there is a lot of fluid in the cavity, it can be compressed Lungs or fluid accumulation for too long will affect lung function and require puncture to remove the fluid accumulation. The current thoracentesis needle needs to use hemostatic forceps to clamp the rubber tube every time the thoracic cavity contents are extracted and the syringe is removed. This method is not only not firm enough, but also leads to the phenomenon of diversion, which has certain harm to the patient. . SUMMARY OF THE INVENTION [0003] The present invention is...
