Problems solved by technology

[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 proc

Embodiment Construction

[0011] Such as figure 1 , the present invention comprises a deep vein puncture needle 1, its tail end is connected with a syringe 2, a piston 3 and a push rod 4 are arranged in the syringe 2, and a spring 5 is arranged in the syringe between the piston 3 and the deep vein puncture needle 1 , The deep vein puncture needle 1 is provided with a valve 6 near the syringe 2 .

[0012] One end of the push rod 4 is connected to the piston 3 , and the other end is provided with a handle 7 .

[0013] The push rod 4 is hollow, the middle part of the piston 3 is provided with a through hole 8, and the end of the push rod 4 close to the handle 7 is sealed with aluminum foil.

[0014] When using the present invention, the air in the needle barrel is first discharged through the piston, and then the valve on the deep vein puncture needle is closed to form a negative pressure in the needle barrel, and the needle starts to be inserted. When the needle is inserted into the trachea, the ai...

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...
