Abstract

The invention relates to a special puncture needle for thyrocricoid puncture and belongs to the technical field of medical appliances. The special puncture needle is characterized by comprising a special injector, a puncture support and a damping fixing ring, wherein the puncture support comprises a support outer frame, a left support arm, a right support arm and a puncture fixing ring, the support outer frame comprises an upper frame body and a lower frame body, a puncture plug hole is formed in the puncture fixing ring, and an annular fixing ring groove is formed in the upper part of the puncture plug hole; the damping fixing ring comprises a ring body with a damping inner hole, and an annular retarding flange is arranged at the upper part of the ring body; when the damping fixing ring sleeves a puncture needle tube, the damping inner hole can tightly wrap the external wall of the puncture needle tube; and when the puncture needle tube is inserted into the puncture plug hole, the external wall of the ring body of the damping fixing ring can fill and plug up the fixing ring groove. The special puncture needle can be used for assisting implementation of thyrocricocentesis, the success rate of the thyrocricocentesis is increased, and injury to sufferers is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a special puncture needle for cricothyroid membrane puncture. Background technique [0002] Cricothyropuncture is one of the first aid methods clinically used for patients with airway obstruction and severe dyspnea. It can buy time for tracheotomy and is an important part of on-site first aid. Such as figure 1 As shown, the existing medical equipment for implementing cricothyrocentesis is simple and simple, only a puncture needle tube, a puncture needle core and a common syringe. The operator pours physiological saline into the syringe, and then connects the front end of the puncture needle core to the injection tube of the syringe , the rear end of the puncture needle core is inserted into the puncture needle tube. If a patient needs cricothyrocentesis urgently, the operator will now disinfect the patient's surgical site, fix both sides of the cricoid cartil...
