Portable cricothyroid membrane puncture needle assembly for thyrocricocentesis

Abstract

The invention provides a portable cricothyroid membrane puncture needle assembly for thyrocricocentesis. The portable cricothyroid membrane puncture needle assembly comprises a hollow puncture needle tube and a translation driving mechanism, wherein the head end of the puncture needle tube is provided with a puncture needle head; the head end of a puncture catheter of the puncture needle assembly is also provided with a structure which is used for wrapping the puncture needle head and is used for buffering and preventing the puncture needle head from further puncturing a trachea after the puncture needle head punctures a cricothyroid membrane; the translation driving mechanism comprises a rotating handle and is used for driving the structure and the puncture needle head to generate relative displacement so as to enable the puncture needle head to retract into the structure; and the tail end of the puncture needle tube is provided with a standard interface. The portable cricothyroid membrane puncture needle assembly is small in size, convenient to carry, remarkable in effect, more reliable in puncture operation, not prone to injuring a patient after puncture, convenient to carry in a standby state, easy to operate in a using state, capable of being operated by non-medical staff and more portable for medical staff, and the rescue success rate of a patient with ventilation disorder caused by airway obstruction is greatly increased.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a portable cricothyroidotomy needle assembly for cricothyroidotomy. Background technique [0002] The cricothyropuncture needle is suitable for patients with acute laryngeal obstruction, especially glottic area obstruction, severe dyspnea, and it is too late to establish an artificial airway. The cricothyroidotomy can be performed quickly to relieve dyspnea. Because people will stop their heartbeat within 2 to 4 minutes of suffocation, and irreversible brain lesions will appear. If the medical staff cannot arrive and treat them in such a short period of time, the chance of the patient surviving is very small, so the rescue at this time Every second counts, and it is best for non-medical staff to operate. This requires that the cricothyropuncture needle must be easy to carry, easy to use, and effective, so that it can relieve the patient's breathing difficulties before ...

AI Technical Summary

Problems solved by technology

[0003] However, some technical points have been neglected in the above-mentioned prior art, which may cause harm to the patient during puncture, specifically: after the puncture needle penetrates the cricothyroid membrane, the needle enters the trachea, as in the puncture, if the puncture If the needle is too large or needs to be punctured deeply, if the puncture depth is not grasped, it may cause the needle to penetrate the trachea or puncture, which will affect the operation and cause harm to the patient

In addition, the puncture needle needs to be sterilized before the puncture, but this point is not taken into account when it is portable, so the time-consuming disinfection may be increased during the operation, resulting in a shorter puncture effective time, which increases the patient's ability to relieve breathing.
