Description
Technical field
This utility model relates to a kind of medical breathing equipment, a kind of more precisely air, oxygen can be mixed by a certain percentage do manually, the device of the usefulness of Self-breathing.
Background technology
Present respiratory organ is of a great variety, as Chinese patent CN93230040.5 disclosed " breathing apparatus ", Chinese patent CN02250648.9 disclosed " medical " from adjust blood pressure changeable flow respiratory organ, these small product size are big, complex structure, very flexible, anti-electronic interferences, not too are fit to pre hospital care, military first aid uses.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of novel empty oxygen mixing respiratory organ.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of empty oxygen mixing respiratory organ, comprise diaphragm piston, respiration channel, source of the gas transfer valve and air inlet valve, bottom one side of diaphragm piston is provided with a secondary cavity, this cavity is connected with diaphragm piston by balancing orifice, its side is provided with air vent, respiration channel is attached thereto logical at the middle position of diaphragm piston, which is provided with air inlet and gas outlet, air inlet is connected with the following oxygen supply port of source of the gas transfer valve, the air inlet valve is set on its pipeline, the gas outlet is connected with secondary cavity by wing passage, the wing passage opening is provided with check valve, and the last oxygen supply port of source of the gas transfer valve is connected with secondary cavity by jet pipe, and the jet pipe opening is corresponding with check valve, the piston core of diaphragm piston links to each other by the control end of connecting rod with the source of the gas transfer valve, and the top of piston core is a manual actuation of button.
The jet pipe of oxygen supply port is provided with the expiration injector on the described source of the gas transfer valve.
The diaphragm top of described diaphragm piston is provided with extension spring, and the extension spring two ends are provided with the sheet spring.
The bottom of described diaphragm piston is provided with and is positioned at the intravital negative pressure in secondary chamber and all presses valve.
The bottom of described diaphragm piston is provided with malleation and all presses valve.
It is spigot joint that described respiration channel connects oxygen supply.
It is spigot joint that the air inlet of described source of the gas transfer valve connects oxygen source.
Operation principle of the present utility model is: when behind the oxygen of source of the gas transfer valve input 0.3～0.35Mpa, press manual actuation of button, this moment, the piston of source of the gas transfer valve was in upper, oxygen just sprays at a high speed through nozzle from following oxygen supply port, exit at the air inlet valve forms certain negative pressure, outside air enters the air inlet valve, and enter in the respiration channel with after the oxygen mix and supply with the patient, pressure in the respiration channel increases in time fast simultaneously, just promoting diaphragm overcomes on the extension spring power and moves, the extension spring two ends are provided with the sheet spring, after extension spring is in poised state, the diaphragm extension spring that moves up slightly just can be bent upwards rapidly, thereby the piston that drives the source of the gas transfer valve by connecting rod slides to the next, finish by air-breathing to the switching of exhaling, oxygen sprays at a high speed through the expiration injector, opening part at jet pipe forms negative pressure, patient's aerofluxus is finished the expiration function, at this moment, the respiration channel internal pressure descends, at the inboard pressure reduction that forms of diaphragm, diaphragm drives extension spring and moves down, and the piston that connecting rod drives the source of the gas transfer valve slides to upper, oxygen sprays into respiration channel from following oxygen supply port again, finishes by the air-breathing switching of exhaling.
This utility model adopts diaphragm piston formula structure, but just Self-breathing after manually booting has pneumatic gas-control, need not power supply, volume is little, in light weight, advantage such as be easy to carry, and is fit to the usefulness of first aid breathing.
