Description
Technical field
The present invention relates to a kind of electronic inductor for oxygen therapy/atomization path switching, belong to what medical institutions used
The component of the medical instruments such as oxygen inhalation apparatus, atomizer, simple respirator.
Background technology
Oxygen therapy and nebulae inhalation are the most common two kinds for the treatment of means of hospital, and are being treated in the more patient of division of respiratory disease
In journey, it is necessary to oxygen therapy and nebulae inhalation alternately.Hospitals at Present generally use oxygen carries out jetting type atomization as power source,
Rotation nasal oxygen tube and two kinds of consumptive material blocked operations of atomizer are needed during this period, and use is very inconvenient.There is inventor's proposition in the country
Oxygen therapy/changeable the oxygen inhalation apparatus of atomization path, switches oxygen therapy/atomization path, but these oxygen using triple valve or push rod
Gas path handoff technique scheme still suffers from larger defect：（1）Whether oxygen therapy/atomization path switches relies on range estimation or feel in place
Control；（2）There are the blind area of control, current path also may not be atomized path, if operation or monitoring neither in oxygen therapy path
It is improper that there are clinical risk.
The content of the invention
The present invention proposes a kind of electronic inductor for oxygen therapy/atomization path switching, mainly by valve body, spool, valve
Core driving device, gas path switching device, inductive switch composition, wherein：
The valve body is generally processed into using metal material extra beds such as copper, aluminium alloys；The side of valve body is equipped with intake channel,
To valve inner, branch becomes oxygen uptake output channel to intake channel after spool, flow monitoring mouth, gas path switching device successively
With being atomized output channel；It is atomized output channel and the setting position of oxygen uptake output channel and layout type is unlimited.The flow of valve body
The periphery of monitoring mouth is equipped with flow measurement device, and for the metering of output gas flow of gas, flow measurement device includes and is not limited to
Flow sensor, flowrator etc..
The spool is located in valve body, and the head of valve body layout corresponding with the air admission hole of intake channel, passes through spool
Controlling opening of valve is rotated forward or inverted, realizes the control of gas outflow amount size.
Device for driving valve body can use adjusting or two kinds of technical solutions of motorized adjustment manually.Manual regulation scheme is usual
One adjusting knob is set in the afterbody of spool, spool displacement control valve aperture is rotated forward or be driven reverse by knob, is adjusted
Save the size of oxygen output flow；Motorized adjustment scheme then usually sets a driving member in the afterbody of spool, driving member with it is straight
The drive division combination linkage work of galvanic electricity machine, drives the Bit andits control valve aperture of spool, adjusting oxygen defeated by direct current generator
The size of outflow.
The atomization output channel uses gas path switching device switching control with oxygen uptake output channel, according to clinical need
Will, atomization output channel is switched mutually with oxygen uptake output channel by push-and-pull/or rotation gas path switching device.Gas circuit switching dress
The concrete mode put includes and is not limited to select triple valve, switching push rod, and by operating triple valve, switching putter action controls oxygen
The conversion of two output channels for the treatment of/atomization；Triple valve includes and is not limited to ball valve, butterfly valve, and switching push rod includes and is not limited to horizontal stroke
To push-and-pull, vertical lifting.
The inductive switch is used for the perception of gas path switching device cutting into position and state, inductive switch specifically include and
It is not limited to microswitch, contact switch, plectrum switch.Inductive switch is separately positioned on gas path switching device at least provided with two
It is cut into oxygen uptake output channel or is atomized the correspondence position that can be triggered during output channel.Lead to when gas path switching device is switched to oxygen therapy
Lu Shi, gas path switching device triggering oxygen therapy inductive switch, inductive switch provide photosignal, prompt gas path switching device accurate
Really it is cut into oxygen uptake output channel；When gas path switching device is switched to atomization path, gas path switching device triggering atomization sensing
Switch, inductive switch provide photosignal, prompt gas path switching device to be accurately cut into atomization output channel；And work as gas circuit
Switching device is not switched to any path of oxygen therapy/atomization accurately, is atomized output channel and oxygen uptake output channel is not smooth
When, at this moment two inductive switches do not trigger, then system would know that gas path switching device is in the blind area of control, prompt again into
The operation of promoting the circulation of qi road switching.
It is an advantage of the invention that：It can be widely applied to the doctor such as oxygen inhalation apparatus of the changeable access structure of oxygen therapy/atomization
Equipment is treated, oxygen therapy/atomization path handoff procedure visualization is high, improves the correctness and comfort of operation, reduces existing
There are the clinical risk that the blind area of control is triggered for oxygen therapy/atomization path handoff technique.
