Description
Technical field
This utility model relates to a kind of gasbag pressure checkout gear and has pressure the laryngeal mask device that quantizes measuring ability, for detection of the pressure condition of laryngeal mask air bag, guarantees the safe handling of laryngeal mask.
Background technology
In order to maintain unconscious patient respiration ventilation, must set up respiration channel to it.Traditional mode is to use tracheal intubation.But there is larger defect in tracheal intubation: be first difficult to fast and suitably pipeline inserted to trachea, because this is a kind of processing procedure of high-tech very, will be by devices such as laryngoscopes toward contact, therefore must there is the operator of certain technology to implement, just make this mode need in patient body, to set up as early as possible respiration channel at some and such as, bring a lot of inconvenience with the situation (critical patient rescue etc.) of striving for treatment time; Secondly, tracheal intubation in use easily causes patient's cardiopulmonary reaction, throat pain, cough or laryngospasm etc., and need to control when inserting patient and cervical region, patient's neck also may be come to harm; In addition, insert for convenient, the distal dimension of tracheal intubation must be enough little, and this just makes the respiration channel of generation less or narrower.
Laryngeal mask airway device is another new device of setting up respiration channel.Use laryngeal mask airway device can insert relatively easily in patient body and set up respiration channel, general operation person just can use through short-term cultivation, therefore also very applicable in the occasion of first aid.Just can inflate to patient's lung because laryngeal mask airway device does not need to contact with the inner passage of trachea sensitivity, therefore the degree of patient's irriate greatly alleviates, and the respiration channel size of setting up is significantly greater than the respiration channel of being set up by tracheal intubation.Meanwhile, less, therefore also less to patient's potential injury to the control action at the positions such as patient's head, neck during due to insertion.Due to above-mentioned advantage, laryngeal mask airway device has become more and more popular since nineteen eighty-three utility model.
But existing laryngeal mask airway device also has its defect: because laryngeal mask use principle is that after inserting throat's inflation, expansion forms air bag elastomer, fit with cavum laryngis, play sealing function, prevent that gas leaks from the gap of laryngeal mask and cavum laryngis in respiratory, be then connected to patient and ventilate with breathing apparatus by the conduit on laryngeal mask.Air bag is generally to adopt the raw materials such as silica gel or plastic cement to make through mould is moulding, form air bag by technique for sticking again, if the own air-tightness of poor attachment or material is bad, this situation under certain pressure, can cause gas leak phenomenon, so just cannot play sealing function, if can not be found in time, just very likely there is medical-risk, can not give safely patient's air feed, this just causes medical personnel to worry to some extent in the time selecting laryngeal mask application, can not more extensively and for a long time use laryngeal mask.
