Operation principle of the present utility model is as follows:
Fig. 1 is that master of the present utility model looks cross-sectional view, Fig. 7 be the outer medicated cap of air valve with the end chamber of the flat-top formation of cylindrical housings in the gas flow sketch map; Fig. 8 is the practical application sketch map of this utility model in laryngeal mask, and whole pressure detecting indication mechanism comprises syringe 9, the pressure indicator 8 that this utility model provides, gas tube 7, laryngeal mask 71.Referring to Fig. 1, Fig. 7 and Fig. 8 are shown in dotted line air flow direction among the figure.Twitch the piston 92 of syringe 9, make in the syringe inner chamber 93 and charge into air, syringe ports 91 is inserted in the connectivity port 31 of the outer medicated cap 3 of elasticity air valve, the upper end head 42 that firmly withstands resilient plug stifled 4 forces resilient plug stifled 4 to produce distortion, the inflation road is opened, the end chamber 32 that forms between the flat-top 21 of outer medicated cap 3 of elasticity air valve and housing 2 is communicated with syringe inner chamber 93, and promotion or twitch syringe piston 92 can be inflated or bleed laryngeal mask cover capsule 6.Air charges into or extracts out approach such as Fig. 1 and shown in Figure 7 of laryngeal mask cover capsule 6, air from syringe inner chamber 93 by because the passage that the distortion of resilient plug stifled 4 is opened enters the elasticity air valve outside the end chamber 32 of formation between the medicated cap 3 and housing flat-top 21, enter the belt chamber 25 of 13 of housing 2 inwalls and elasticity membrane vesicle cyst membranes again via the passage on the flat-top 22, enter the inner chamber of gas tube 7 by the cover bag hole roads 52 that communicate with laryngeal mask cover capsule 6 in the union joint 5 and with the pipe joint air flue 54 that gas tube 7 joins then, enter the inner chamber of laryngeal mask cover capsule 6 at last.In the process of laryngeal mask cover capsule 6 being inflated and bleeding, elasticity membrane vesicle 1 can be to intrinsic pressure the reacting of laryngeal mask cover capsule 6, thereby the compression and the stretching, extension of elasticity membrane vesicle 1 can appear, indication black ring 17 on this moment elasticity membrane vesicle 1 can be followed the compression of elasticity membrane vesicle 1 and stretching, extension and displacement be occurred, cooperates the scale 28 on the housing 2 just can indicate the intrinsic pressure situation of laryngeal mask cover capsule 6.The doctor can grasp the intrinsic pressure situation of laryngeal mask cover capsule 6, thereby the intrinsic pressure of laryngeal mask cover capsule 6 judged accurately by to the observation of black ring 17 with respect to the change in displacement of scale 28.
The intrinsic pressure reaction of making of 1 pair of laryngeal mask cover of elasticity membrane vesicle capsule 6 is such, when to laryngeal mask cover capsule 6 inflation or when oxynitride taking place diffusing in the laryngeal mask cover capsule 6, the 6 intrinsic pressure increases of laryngeal mask cover capsule, elasticity membrane vesicle 1 is made compression reaction, and black ring 17 will be to the direction displacement of the housing bottom of pressure indicator; Otherwise when laryngeal mask cover capsule 6 being bled or during generating cover capsule gas leak phenomenon, laryngeal mask cover capsule 6 intrinsic pressure reducing, elasticity membrane vesicle 1 is made and is stretched reaction, and black ring 17 will be to the vertical direction displacement of the housing of pressure indicator.
The doctor is when the charge operation of carrying out laryngeal mask cover capsule 6, can observe the change in displacement of pressure indicator black ring 17 while inflating, thereby the intrinsic pressure of laryngeal mask cover capsule 6 judged when laryngeal mask cover capsule 6 intrinsic pressure reached needed pressure (being generally 60 centimeter water columns), the doctor stopped inflation.Equally, after inflation is finished, if the intrinsic pressure generation of laryngeal mask cover capsule 6 increases or during the variation that reduces, according to the displacement of the black ring 17 in the pressure indicator, the doctor can take the bleeding or the inflation measure of laryngeal mask cover capsule 6, thus make laryngeal mask cover capsule 6 intrinsic pressurely remain on suitable size.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
