Description
Technical field
The present invention relates to a kind of gasbag pressure checkout gear and there is the laryngeal mask device that pressure quantizes measuring ability, for detecting the pressure condition of laryngeal mask air bag, guaranteeing the safe handling of laryngeal mask.
Background technology
In order to maintain the ventilation of unconscious patient respiration, respiration channel must be set up to it.Traditional mode uses tracheal intubation.But there is larger defect in tracheal intubation: be first be difficult to fast and suitably pipeline inserted trachea, because this is a kind of processing procedure needing very high-tech, will by devices such as laryngoscopes toward contact, therefore the operator of certain technology must be had to implement, just make this mode in patient body, set up respiration channel as early as possible to strive for that the situation (such as critical patient rescue etc.) for the treatment of time brings a lot of inconvenience at some needs; Secondly, tracheal intubation in use easily causes that the cardiopulmonary of patient reacts, throat pain, cough or laryngospasm etc., and owing to needing head and the cervical region of control patient when inserting, patient's neck also may be come to harm; In addition, conveniently insert, the distal dimension of tracheal intubation is sufficiently little, and this just makes the respiration channel of generation less or narrower.
Laryngeal mask airway device is that another sets up the new device of respiration channel.Use laryngeal mask airway device to insert in patient body relatively easily 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 the lung of patient 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 set up significantly is greater than the respiration channel set up by tracheal intubation.Meanwhile, owing to inserting less, therefore also less to the potential injury of patient to the control action at the positions such as patient's head, neck time.Due to above-mentioned advantage, laryngeal mask airway device has become more and more popular since nineteen eighty-three invention.
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 in respiratory gas from leaking from the gap of laryngeal mask and cavum laryngis, be then connected to patient ventilation with breathing apparatus by the conduit on laryngeal mask.Air bag is generally adopt the raw material such as silica gel or plastic cement to make through mould is moulding, air bag is formed again by technique for sticking, if poor attachment or the air-tightness of material own bad, can gas leak phenomenon be caused under a certain pressure, so just cannot play sealing function, if this situation can not Timeliness coverage, just very likely there is medical-risk, can not give patient's air feed safely, this just causes medical personnel to worry to some extent when selecting laryngeal mask application, more extensively and for a long time can not use laryngeal mask.
Summary of the invention
