Definitions

  • the present invention relates to a method of making a laryngeal mask and a laryngeal mask.
  • the function of the laryngeal mask is to maintain the breathing of unconscious patients such as patients with drenched body, and to establish a respiratory passage for patients. It is a component of the clinical operation of important clinical treatment measures such as critically ill patients, surgical anesthesia and cardiopulmonary resuscitation.
  • the laryngeal mask generally includes a membrane-type air bag, an air tube, and an inflation tube.
  • the air bag is located at one end of the air tube, and the air tube is connected to the air bag.
  • the existing airbag is made by blow molding, and the outer surface of the airbag thus produced has a mold clamping line, which not only makes the patient feel uncomfortable in use, but also damages the patient's throat wall. Therefore, according to the clinically more scientific and humanized treatment needs, it is imperative to improve and innovate the existing laryngeal mask.
  • the present invention provides the following technical solutions.
  • the invention provides a method for manufacturing a laryngeal mask, comprising the steps of: manufacturing an integral mold for forming an airbag, having a step on the inner side of the mold; placing the mold into the PVC slurry; taking out the mold and heating it in a heating box Forming; taking out the formed airbag and fixing the air guiding tube to one surface of the step; opening and removing the mold on the other surface of the step; and closing the opening.
  • the present invention also provides another method for manufacturing a laryngeal mask, comprising the steps of: manufacturing an integral mold for forming an airbag, having a step on the inner side of the mold; preheating the mold; and placing the preheated mold into the PVC slurry Removing the mold and placing it in a heating box for heating; taking out the formed airbag and fixing the air guiding tube to one surface of the step; opening and removing the mold on the other surface of the step; and closing the opening.
  • the mold is fixed to one surface of the step by glue.
  • the opening is closed by glue.
  • the temperature in the heating box is the temperature at which the PVC matures.
  • the present invention also provides a laryngeal mask made by the above-described laryngeal mask manufacturing method.
  • the outer surface of the airbag made by using the integral mold has no mold clamping line, which solves the discomfort and the patient's discomfort caused by the mold clamping line formed by the blow molding method in the prior art.

  • the mold 200 when the air guiding tube 10 is fixed to one surface of the step 202, the mold 200 is inside the airbag 20, so that the mold 200 supports the step 202 of the airbag 20, which is advantageous for fixing the air guiding tube 10 to one surface of the step 202. Moreover, when the opening is closed, the airway tube 10 supports the step 202 to facilitate closure of the opening.

Abstract

La présente invention concerne un procédé de fabrication d'un masque laryngé et le masque laryngé, comprenant les étapes de fabrication suivantes : fabrication d'un moule intégral (200) utilisé pour fabriquer un sac gonflable, dans lequel un gradin (202) est agencé sur le côté interne du moule (200) ; placement du moule (200) dans une suspension concentrée de PVC ; retrait du moule (200) et placement du moule dans une boîte chauffante, et chauffage du moule pour formage ; retrait d'un sac gonflable formé (20) et fixation d'un tuyau de guidage d'air (10) à une surface du gradin (202) ; formation d'une ouverture sur l'autre surface du gradin et retrait du moule ; et fermeture de l'ouverture. Le sac gonflable est fabriqué au moyen du moule intégral et ne comporte pas de ligne de jonction sur la surface externe de celui-ci, permettant ainsi de résoudre les problèmes d'inconfort pour les patients et les dommages à la gorge causés par un sac gonflable avec des lignes de jonction fabriqué au moyen d'un procédé de moulage par soufflage de l'art antérieur.
