Cricothyroid membrane puncturing and ventilating device

Abstract

The invention relates to a medical apparatus, in particular to a first-aid disposable cricothyroid membrane puncture airing device which is provided with an arc-shaped puncture needle, the back end of the puncture needle is provided with a column-shaped handle, the invention is characterized in that the puncture needle is externally provided with an arc-shaped sleeve, the column-shaped handle is sheathed with a respiration adapter tube, the arc-shaped sleeve is connected with the respiration adapter tube, the respiration adapter tube is connected with a respiration air source via an air duct, when in use, the arc-shaped sleeve and the respiration adapter tube are sheathed on the arc-shape puncture needle and the column-shaped handle, a respiration adapter tube sleeve and the column-shaped handle are positioned by a concave groove and a convex pad, a handheld respiration adapter tube sleeve is used for piercing the arc-shaped puncture needle and the arc-shaped sleeve into the position of the cricothyroid membrane, then, the concave groove and the convex pad are separated, the arc-shaped puncture needle is taken out by the column-shaped handle, and the air duct and the respiration adapter tube are fast plugged with each other to carry out artificial respiration for the patient, the air duct can be connected with a handheld respiration air bag or a respiration machine, the condition of the patient is observed to ensure that the arc-shaped sleeve and the respiration adapter tube can be positioned by a positioning band after the airing is smoothened. The invention has the advantages of convenient use, short operation period, good respiration effect, low operation cost, high success ratio of emergency treatment, etc.

Description

Technical field: [0001] The invention relates to a medical appliance, in particular to a disposable cricothyroid membrane puncture ventilator for first aid. Background technique: [0002] As we all know, acute laryngeal obstruction due to various reasons is an emergency and severe disease in various clinical departments, such as acute laryngitis, acute laryngeal edema of various reasons, foreign body obstruction in the laryngeal, acute epiglottitis, trauma to the head, neck or larynx, patients under general anesthesia Difficult-to-insert endotracheal intubation or tongue base retrograde obstruction after general anesthesia, if not treated in time, will cause the patient to die of respiratory asphyxia. At present, patients with laryngeal obstruction are often encountered in medical emergency and surgical anesthesia. In order to save the patient's life, emergency endotracheal intubation and tracheotomy or cricothyrotomy are required. Specialists are required to perform this op...

Problems solved by technology

Although this method can solve temporary ventilation, due to the limitation of the ventilation channel of the puncture needle, the ventilation volume cannot meet the needs of human breathing tidal volume, and at the same time, the patient is still in a state of hypoxia due to the inability to assist oxygen supply or connect to a ventilator to assist breathing. , thus failing to achieve the purpose of relieving laryngeal obstruction and continuing to threaten the patient's life
