Abstract

The invention relates to a novel cricothyroid membrane puncture needle. The puncture needle is characterized in that an outer tube (1) is provided with a tube body (9) which is a straight round tube,a head end tube orifice (3) is arranged at the head end of the tube body (9), a tail end tube orifice (5) is arranged at the tail end of the tube body (9), a through port (4) is arranged above the head end tube orifice (3) in a manner of being perpendicular to the tube body (9), a first tube handle (6) and a second tube handle (8) are vertically arranged on the tube body (9) parallelly, tube handle small holes (7) are formed in the left and right ends of the first tube handle (6) and used for thread ropes to penetrate, a tube core (2) is provided with a straight tube (11) which is slightly thinner than the outer tube (1), the straight tube (11) can be put into the outer tube (1), and the head end of the straight tube (11) is a triangular-pyramid-shaped head end (10) while the tail end of the same is spherical tail end (12). The puncture needle is simple and convenient to operate, accurate in puncture, capable of immediately relieve throat obstruction and less prone to causing damage toother normal tissue.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a novel cricothyroid membrane puncture needle used for the throat of the upper respiratory tract. Background technique [0002] In daily life, it is common for children to inhale laryngeal cavity by mistake when eating jelly and other foods, causing shortness of breath and acute laryngeal obstruction, causing dyspnea, and suffocation in severe cases. At this moment, the airway needs to be unblocked urgently to ensure smooth breathing. The patent number is 200820188282.2 The new cricothyroid membrane puncture needle is a 1 / 4 circle curved tubular structure, and its biggest disadvantage is: when puncturing the neck cricothyroid membrane, it has to go through the skin, subcutaneous fat and the tough tissue of the ligament in the cricothyroid membrane, and cannot pierce the cricothyroid membrane. If it enters the laryngeal cavity, the purpose of relieving dyspnea cannot be achieved, and the thyr...
