Description
Technical field
Pressure measurement and knowledge technology field, especially relate to when the utility model belongs to disposable sterilized laryngeal mask Clinical practice
And a kind of laryngeal mask gasbag pressure shows table.
Background technology
Disposable sterilized laryngeal mask is a kind of a kind of novel gas passage equipment occurred in recent years, it is for during surgery
Anesthetic gases and oxygen are sent into unconscious device in patient body, are widely used clinically.Its basic structure includes logical
Airway and air passage after bottleneck throat, make vent hood be located at hypopharynx after air passage insertion, and are formed around throat close
It closes.When intubating laryngeal mask airway is normally inserted into, after inflation, laryngeal mask cover capsule can form a sealing ring, the blowing pressure around throat
It controls in reasonable range, thus establishes artificial airway rapidly, establish after artificial airway and lay a good foundation for anaphase；
The case where for the ease of showing the pressure in laryngeal mask air bag, medical staff being facilitated to understand established artificial airway in real time, generally
Pressure-display device is configured, for supervising laryngeal mask intracapsular pressure value；Existing market mainly refers to using a kind of gasbag pressure
Show device, Patent No. ZL200820074424.2, the product mainly by medical staff according to the deformation size of bellows come
Judge the size of pressure, error is larger existing for this mode, higher to the skill requirement of medical staff, and in qi of chong channel ascending adversely or
Illusion is easy tod produce when pumping, and then causes pressure excessive or too small.
In addition, a kind of this dial type micro-pressure indicator is also disclosed on patent database, number of patent application is
201510589313.X, product that this foundation patent document produces at present do not find that it is primarily present as follows also on the market
Defect, first, used air bag shown in patent application document is ellipse, fan-shaped, triangle or quadrilateral structure,
The stress deformation of air bag is analyzed from amechanical angle there are irregular, therefore when have after pressed gas can not be along for punching in air bag
One Direction distortion, reduces so as to cause the utilization rate of distortional stress, also just says that deformation force cannot be maximum when air pressure change is
Limit acts on a unidirectional stress point；Secondly utilize a push plate along slideway according to shown in patent application document

Dynamic is smooth, or even will appear stuck phenomenon, once the function that stuck pressure is shown will make its effect, if medical staff does not have
Anticipation, which will be stuck phenomenon, to be continued growing, and certainly will have security risk in this way；Third, according to pointer shown in patent application document
Reset by spring realize reset, using spring reset, firstly there are pressure errors, can not react air bag authentic and validly
True pressure；4th, according between push plate and case shown in patent application document there are larger contact surfaces, and then cause to slide
It is dynamic unsmooth, it is dumb to cause to rotate, show inaccurate defect；5th, it is profit according to the present invention shown in patent application document
It pushes rack to realize the patent of pointer with moving gear rotation again with air bag, but since the variation of air bag is irregular, goes out sometimes
Existing push plate pushes rack to press to gear diameter direction, can not rotate or rotate the unsmooth problem of rotation so as to cause gear, into
And inaccurate problem can not be shown or show by causing stress.
In addition, a kind of low pressure alarming pressure gauge is also disclosed, patent No. ZL200710012390.4, a kind of diaphragm type pressure
