Thyrocricocentesis needle

Abstract

Disclosed is a thyrocricocentesis needle. The thyrocricocentesis needle comprises a deep vein puncture needle, the tail end of the deep vein puncture needle is connected with a needle tube, the inside of the needle tube is provided with a piston and a push rod, the inside of the needle tube between the piston and the deep vein puncture needle is provided with a spring, and the portion of the deep vein puncture needle, which is closed to the needle tube, is provided with a valve; one end of the push rod is connected with the piston, and the other end of the push rod is provided with a handle. The thyrocricocentesis needle can ensure that the needle punctures a trachea, and is easy to operate, accurate in location, safe and practical. Besides, the thyrocricocentesis needle can reduce the risks of mis-puncturing an esophagus or a great vessel as well as the operating difficulty of a doctor holding the needle in a negative-pressure mode in inserting the needle, so that the doctor can more concentrate on judgment of anatomic layers to avoid the risk of mis-puncture.

Description

technical field [0001] The invention relates to a medical device, in particular to a cricothyroid puncture needle. 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 also a necessary way for retrograde tracheal intubation. [0003] At present, there are no special regulations and requirements for cricothyroid puncture tools. In clinical practice, thick needles over 16G are mostly used, and epidural puncture needles are often used in anesthesiology departments. Since the depth of the needle cannot be observed during the needle insertion process, puncture may occur Injury to blood vessels or accidental injury to the esophagus when the needle is inserted too deep can lead to complications such as bleeding and esophageal perforation. In severe cases, the patient can suffer from suffocation, esophagotracheal fistula complicated by severe in...
