Description
Technical field
It is the utility model relates to field of medical device, in particular to a kind of with the gas for pressing non-dissociation formula air bag from survey
Cannula.
Background technique
Trachea cannula is to be placed in a special endotracheal tube in tracheae or bronchus through throat by oral cavity or nasal cavity
Method, stop suddenly suitable for autonomous respiration, acute respiratory failure or be not able to satisfy needing mechanical logical for oxygen demand for body
Gas person is the important measures for rescuing respiratory dysfunction patient.
Wherein, the air bag on trachea cannula plays the role of very important, and air bag inflated size and aeration quantity stability are determined
Determine whether first aid succeeds.Air bag inflation is excessive easily to pull throat, causes throat, tracheal injury, under-inflation is then unfavorable for exhaling
It inhales, or even tracheae obscission occurs.In addition, the operation when stability of air bag aeration quantity ensure that surgical is smooth, subtract
A possibility that few unexpected burst.
Current most of doctors touch to be connected with air bag by experience when using trachea cannula with hand indicates sacculus
Aeration quantity judges to be inserted in the size of the air bag aeration quantity of bottleneck throat position in patient's mouth.This method is pure to lean on experience and feel,
The judgement of ununified judgment criteria, doctors is easy for there are deviation so that operation error leads to operative failure, delays treasured
Expensive emergency time.To solve this problem, hospital mostly uses German VBM air bag manometric method, when work external one on air bag
Pressure gauge injects air to air bag simultaneously, and pressure removes pressure gauge after stablizing.However this method is cumbersome, surveys pressure solution every time
From when, charge valve can reveal a certain amount of gas, can all decline 1-2mmHg so as to cause air pressure in air bag, and former barometer reading
It deviates, furthermore can similarly be led to the problem of when air charging system inflation finishes dissociation similar.Because of air bag small volume,
So the air pressure that manograph dissociation and air syringe lose when taking out can not be ignored easily, it should guarantee the true of barometric surveying as far as possible
Real stability reduces operation risk.However, not yet being proposed rationally to pressure error caused by this phenomenon in the prior art
Solution.
Utility model content
The purpose of the utility model is to overcome disadvantage mentioned above, provide a kind of survey with oneself and press non-dissociation formula air bag
Trachea cannula, which overcome the charge valve gas leakage when inflating or dissociation is pressed in survey to cause the problem of air pressure declines in air bag.
The utility model is achieved through the following technical solutions: a kind of with slotting from the tracheae for surveying the non-dissociation formula air bag of pressure
Pipe, it is characterised in that: including gas-guide tube, air bag, tracheae connector and air bag inflatable component；The air bag is nested with to be fixed on and lead
On the periphery wall of tracheae front, tracheae connector is fastened on the opening of gas-guide tube rear end；
The air bag inflatable component includes that gas tube, three-way diverter valve, inflating balloon, inflation check valve and outlet are unidirectional
Valve；One end of the gas tube extends at air bag along the tube wall of gas-guide tube and is connected to inside air bag, and the other end passes through outlet
Check valve is connected to the internal cavity of inflating balloon, and the company of the inside on inflating balloon and with inflating balloon is arranged in inflation check valve
It is logical；The three-way diverter valve is arranged on gas tube, and the first port of three-way diverter valve is connected to by gas tube with air bag, and second
Port is connected to outgassing nonreturn valve, and third port is in communication with the outside, and being equipped in three-way diverter valve makes first port and second port
The spool for being connected to or being connected to first port with third port.
Its working principle and process are as follows:
Three-way diverter valve is adjusted to air-suction state first, so that outside air is passed through inflation check valve by squeezing inflating balloon
It is flow in inflating balloon and air bag with the first, second port of three-way diverter valve.When the air pressure in air bag reaches preset air pressure,
It can stop inflating；When air bag pressure is more than scheduled air pressure, then release is carried out by the third port of three-way diverter valve, make it
Drop to scheduled air pressure range.Air bag inflatable component ensure that the stability of air bag pressure, while remaining gas in inflating balloon
Body may further be used to fine tuning air bag pressure.When needing to carry out bleed air operation to air bag, three-way diverter valve can be adjusted to out gaseity,
Conduit is connected with the third port of three-way diverter valve, flows the gas in air bag naturally
Out.
Why the program is not in when inflating or survey pressure dissociation in background technique from charge valve, due to charge valve air pressure
The problem of leakage causes air bag pressure to reduce, reason is: with inflating balloon instead of original charge valve, squeezing sacculus
It is inflated, dissociation process is not necessarily to, and there are also partial airs to be stored in inflating balloon, even if sacculus gas leakage nor affects on gas
Capsule air pressure, to ensure that the stabilization of inside air bag pressure.
For better implementation this programme, following prioritization scheme is also provided:
Further, in order to accurately grasp the air pressure size in air bag: it further include pressure test component, the pressure test group
Part includes air bag manograph, pressure-measuring pipe and three-way connection；
The first interface of the three-way connection is connected to by gas tube with air bag, and second interface is changed by gas tube and threeway
It is connected to valve with inflating balloon, third interface is connected to by pressure-measuring pipe with air bag manograph.
Further, in order to make the air pressure size in air bag be easy to observe: the air bag manograph includes that shell, pressure refer to
Show block, piston and elastic component；The pressure instruction block is movably arranged on enclosure interior, and piston is fixed on pressure instruction block
Top, elastic component upper end are fixed on the lower part of pressure instruction block, and lower end is fixed on inner sidewall in the lower part of the housing；The shell
Top be equipped with pressure tap for being connected to pressure-measuring pipe, pressure observation window is provided in the middle part of shell, pressure indicates the outer of block
The direction being moved along it on surface, which is sequentially coated with, more than two shows pressure color lump.
Further, in order to guarantee manograph energy normal use: the elastic component is spring, torsional spring or elastic rubber.
Further, in order to quickly determining air bag pressure size: described to show that pressure color lump includes red color lump, green color lump
And yellow color lump and be from top to bottom sequentially distributed pressure instruction block outer surface on.
The pressure color lump, yellow representative pressure is insufficient, and green area representative pressure is moderate, and red area indicates pressure mistake
Greatly.
