A bendable laryngeal mask with a positioning guide core and its application method

Abstract

The invention discloses a bendable laryngeal mask with a positioning guide core and a use method thereof, comprising a laryngeal mask body, a positioning guide core and a disposable transparent protective cover; the laryngeal mask body includes a ventilation tube and a mask connected with it body, the positioning guide core can be placed into the ventilation tube; the positioning guide core includes a bendable mirror body with adjustable bending arc; a limit assembly that can fix the bendable mirror body and the ventilation tube is provided on the bendable mirror body When in use, the flexible mirror body with a disposable transparent protective cover is inserted into the ventilation tube, and placed in the mouth and pharynx along with the laryngeal mask, and the limiting component can prevent relative displacement between the flexible mirror body and the ventilation tube. The advantage of the present invention is that the tightness of the contact between the ventilation tube and the flexible mirror body is controlled by the limit assembly, which improves the force conduction, not only can significantly improve the success rate and insertion quality of the flexible laryngeal mask for the first time, but also Can ensure full visibility.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a bendable laryngeal mask with a positioning guide core and a use method thereof. Background technique [0002] In recent years, the flexible laryngeal mask has been widely used clinically because of its soft ventilation tube, flexible fixed position, large operating space for doctors in the oral cavity and head and neck, and less damage to the patient's oropharynx and throat. However, while the flexible laryngeal mask has the above advantages, there are also some disadvantages, that is, the softness of the ventilation tube increases the difficulty of its placement. At present, the insertion method of the flexible laryngeal mask still adopts the classic laryngeal mask insertion method: the flexible laryngeal mask is gently slid down to the entrance of the esophagus along the midline of the incisors, hard palate, and posterior pharyngeal wall with bare hands. Gently rotate ...

AI Technical Summary

Problems solved by technology

However, the diameter of the tracheal intubation guide core is too thin compared to the laryngeal mask ventilation tube, so it is easy to make the laryngeal mask ventilation tube and the mask body rotate around the guide core

The rotation of the laryngeal mask on the endotracheal intubation guide core, coupled with the poor conductivity of the force of the flexible ventilator, often causes deflection and improper insertion depth of the mask after being placed in the pharyngeal cavity

At the same time, this method is a blind detection operation, and there are problems that the operator cannot immediately see whether the mask body is in a proper position, whether it is deflected, whether the size of the laryngeal mask fits the patient's pharyngeal cavity structure, etc.

Failure to insert the laryngeal mask or the insertion position is not satisfactory, often requiring repeated insertions, which will undoubtedly increase the chance of damage to the oropharynx
