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

Embodiment 1

[0054] Such as figure 2 As shown, the limiting component is an airbag structure, and the airbag structure includes a columnar airbag 4, an inflation valve 5, and an inflation tube 6. The columnar airbag 4 and the inflation tube 6 are covered outside the bendable mirror body, and the columnar airbag 4 communicates with the inflation tube 6 to Valve 5 is connected. When inflating the columnar airbag 4 through the inflation valve 5, the columnar airbag 4 expands and fits closely with the inner wall of the vent tube 10 lumen, and the bendable mirror body is locked and fixed; when the gas in the columnar airbag 4 is drawn out through the inflation valve 5 , the columnar airbag 4 is deflated and separated from the inner wall of the vent tube 10, and the position of the flexible mirror body 2 is adjustable.

[0055] Insert the positioning guide core into the ventilation tube 10, inflate the columnar airbag 4, and the columnar airbag 4 expands to fix the relative position of the out...

Embodiment 2

[0062] Such as image 3 As shown, the limit assembly is a spring structure, the spring structure includes a spring ring 8 and a spring fixed body 9, the spring fixed body 9 is sleeved outside the outer sleeve, and the upper part of the spring fixed body 9 is connected to the spring ring 8 through a buckle. When the spring pull ring 8 is pulled, the spring fixed body 9 is stretched, the spring fixed body 9 is separated from the inner wall of the vent tube 10, and the position of the bendable mirror body is adjustable; when the spring pull ring 8 is released, the spring fixed body 9 After reset, the spring fixed body 9 is closely attached to the inner wall of the vent tube 10, and the bendable mirror body is locked and fixed.

[0063] Such as Figure 4~5 As shown, the guide core assembly is placed in the vent tube 10, when the spring pull ring 8 is pulled, the spring fixed body 9 is stretched, and the spring fixed body 9 contacts with the vent tube 10 loosely; when the spring p...

Abstract

The invention discloses a flexible laryngeal mask with a locating guide core and a using method thereof. The flexible laryngeal mask comprises a laryngeal mask body, the locating guide core and a disposable transparent protection sleeve; the laryngeal mask body comprises a ventilating pipe and a cover body communicated with the ventilating pipe, and the locating guide core can be placed in the ventilating pipe; the locating guide core comprises a flexible mirror body with adjustable radian; a limit assembly capable of fixing and clamping the flexible mirror body and the ventilating pipe is arranged on the flexible mirror body; in the using process, the flexible mirror body with the outer portion sleeved with the disposable transparent protection sleeve is inserted in the ventilating pipe and placed in the pharynx oralis along with the laryngeal mask body, and relative displacement is not generated between the flexible mirror body and the ventilating pipe through the limit assembly. Theflexible laryngeal mask has the advantages that whether or not the contact between the ventilating pipe and the flexible mirror body is close is controlled by the limit assembly, the force transmission is improved, the success rate and quality of first-time placing of the flexible laryngeal mask can be significantly improved, and it can be ensured that the whole process is visible.

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 ...
