Description

The gas circuit switch prompting method of respirator and respirator
Technical field
The present invention relates to medical instruments field, relate in particular to the gas circuit switch prompting method of respirator and respirator.
Background technology
Respirator is that it possesses three kinds of gas output functions conventionally for the equipment to patient's oxygen gas-supplying or respirable mist, that is: supplemental oxygen output, argoshield output and the output of circulatory and respiratory gas.Correspondingly, this respirator need be provided with three gas output end mouths, that is: supplemental oxygen output port, argoshield output port (it can be described as again auxiliary live gas outlet, and corresponding English is Auxiliary Common Gas Outlet (ACGO)) and circulatory and respiratory gas output end mouth.
Above-mentioned three kinds of gases output is by air (Air), oxygen (O by respirator 2) and laughing gas (N 2o) one or more in is mixed to get mutually.In addition, the function that this respirator also can have anesthetics volatilization and carry, now this respirator can be described as again anesthetic machine or anesthesia respirator.
This respirator is when operation, and above-mentioned three gas output end mouths at a time can only have one in running order (that is, in upstate), that is to say and can not have plural gas output end mouth to export gas simultaneously.Therefore, importantly to understand which gas output end mouth in running order with will be clear that for user (for example, clinician), to guarantee, according to pre-provisioning request, desired gas flowed to patient.
Fig. 1 is that a kind of gas of existing respirator is carried schematic diagram.As shown in the figure, in the gas circuit between gas source 1 and gas output port 4 (do not indicate), be provided with volume control device 2, total flow meter 31, selector valve 32, selector valve 33 and selector valve 34 etc., to realize, the various gases from gas source 1 mixed and be transported to gas output end mouth 4.This gas source 1 specifically comprises air source 11, source of oxygen 12 and laughing gas source 13, and this gas output end mouth 4 specifically comprises supplemental oxygen output port 41, circulatory and respiratory gas output end mouth 42 and argoshield output port 43.This volume control device 2 comprises corresponding with air source 11, source of oxygen 12 and laughing gas source 13 respectively air flow control valve 21, oxygen flux control valve 22 and laughing gas flow control valve 23, they can be mechanical flow control valve or electronic flow control valve, in order to control the flow of various gases.This selector valve 32, selector valve 33 and selector valve 34 mix various gas for the setting according to user and mixed gas are correctly transported to supplemental oxygen output port 41, circulatory and respiratory gas output end mouth 42 or argoshield output port 43.
Certainly, from gas source, to the gas gas output end mouth, carry and also can adopt alternate manner.For example,, referring to No. 201,0/0,175,695 A1, U.S. Patent Application Publication US and No. 201010620493.0 disclosed anesthetic machines of Chinese patent application CN.
In above-mentioned respirator (comprising anesthetic machine), user need to rule of thumb judge which gas is mixing and will be transported to which gas output end mouth.This exists the risk of erroneous judgement, thereby likely correctly desired gas is not flowed to patient, and potentially patient is damaged.
Therefore, be necessary to provide a kind of gas circuit switch prompting method that overcomes respirator and the respirator of above-mentioned shortcoming.
