Description

Double-sleeve laryngeal mask for anesthesia endoscope

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a double cannula laryngeal mask for anesthesia scope.

Background

Since the invention of the laryngeal mask in 1981, it has been widely used for clinical anesthesia. The laryngeal mask is used as a special supraglottic ventilation tool, and has the advantages of simple and convenient operation, easy mastering, high success rate of placing by beginners, small stimulation to air passages, tolerance under shallow anesthesia, more stable hemodynamics of patients in induction and recovery periods, less complication after laryngeal mask operation and the like. Therefore, the laryngeal mask has become the most important airway device outside the tracheal tube at present, and is widely used for airway management of patients in general anesthesia operation at home and abroad, treatment of emergency airways and intubation of difficult airways. Currently, there are three types of laryngeal masks commonly used by adults: the selection is carried out according to the actual weight provided by a laryngeal mask manufacturer, namely, the laryngeal mask No. 3 is selected for 30-50 kg of weight, the laryngeal mask No. 4 is selected for 50-70 kg of weight, and the laryngeal mask No. 5 is selected for more than 70kg of weight. Each patient selects the laryngeal mask with the corresponding model according to the weight of the patient, however, in the clinical practical use process, the laryngeal mask selected according to the actual weight cannot achieve satisfactory ventilation when in use, because the laryngeal mask model selected according to the weight of the patient is not suitable, the glottis of the patient cannot be completely sealed at the mask opening, so that air leakage occurs in ventilation, the laryngeal mask model needs to be replaced at the moment, the original unmatched laryngeal mask is pulled out, and the laryngeal mask with the size of one larger or one smaller is selected again to be placed until the satisfactory ventilation is achieved. Therefore, once the laryngeal mask is changed, the original laryngeal mask needs to be pulled out and a new laryngeal mask needs to be placed again, so that extra oropharyngeal injury can be caused to the patient; in addition, the unmatched laryngeal mask also incurs a certain financial loss to the patient, since it is charged a certain amount. Therefore, there is a need for a new type of double cannula laryngeal mask for use with an anesthetic endoscope.

For example, chinese patent publication No. CN209137659U discloses a double cannula laryngeal mask for an anesthetic endoscope that includes an integral silicone balloon. This integral type silica gel sacculus is provided with the sputum and collects the chamber.

The inboard in sputum collection chamber is provided with the both ends and all runs through the pipe of putting into of integral type silica gel sacculus and put into the inboard fixed outer tube that has cup jointed to be located breather pipe one side. The inboard cover of outer tube is equipped with inner tube and the tip of inner tube is provided with and is used for dismantling the joint subassembly of being connected with the outer tube. The utility model discloses an adopt the double cannula setting that outer tube and inner tube combine to can make the card post stretch out then and make outer tube and inner tube can separate from the draw-in groove through the joint subassembly that sets up when making the laryngeal mask can be used for using with the gastroscope cooperation through the setting. However, the utility model still has the following technical disadvantages: because the utility model that this utility model laryngeal mask can be changed only has three kinds, and when patient or the laryngeal mask model that medical staff chooseed for use do not necessarily match completely with patient's oropharynx, still need change original laryngeal mask, consequently still need pull out original unmatched laryngeal mask, so just can cause extra oropharynx damage for the patient, also lead to the fact certain economic loss for the patient simultaneously.
