Laryngeal mask model selecting tool safe, easy and convenient to use

Abstract

The invention relates to a laryngeal mask model selecting tool safe, easy and convenient to use. The tool is provided with two bent measuring arms. Each measuring arm is provided with a front measuring arm, a hinged section and a rear measuring arm from the head end to the tail end in sequence. The two measuring arms are hinged through a hinge shaft at the hinge sections. A finger ring is arranged at the tail end of each measuring arm, and an elliptic gasket is movably connected to the side wall of the outer side of the head end of each measuring arm; one end of a graduated disc is fixed to the side wall of the inner side of the rear measuring arm of the first measuring arm, and the other end of the graduated disc penetrates through a through hole in the rear measuring arm of the second measuring arm and stretches out of the second measuring arm; a laryngeal mask identifier is arranged on the graduated disc. By applying the laryngeal mask model selecting tool, the laryngeal mask model most suitable for the volume of the laryngeal part of pharynx of a patient can be determined safely, accurately, easily, conveniently and rapidly, the postoperation complications of the laryngeal part of pharynx of the patient are remarkably reduced, the postoperation comfort and satisfaction of the patient are greatly improved, and the great clinic application value is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a safe and convenient laryngeal mask model selection tool. Background technique [0002] Since the British anesthesiologist Archie Brain invented the laryngeal mask in 1981, the laryngeal mask has been widely used in clinical anesthesia. The laryngeal mask is placed in the patient's throat. As a special type of supraglottic ventilation tool, it has the advantages of easy operation, high success rate of placement, little airway irritation, good patient tolerance, and little impact on hemodynamics. Retaining the advantages of spontaneous breathing to maintain anesthesia, less postoperative complications, and easy to master, it has become the most important airway device besides the tracheal tube, and is widely used in the airway management of patients in general anesthesia operations at home and abroad, and emergency airway management. Management and intubation of diff...

AI Technical Summary

Problems solved by technology

Tongue width can accurately reflect the volume of the throat, but the width of the tongue will vary with the length of the tongue protruding from the mouth, and there will be errors in the measurement, or the patient is thin and the tongue is huge, these factors will increase the probability of choosing the wrong model
