Abstract
A medical oxygen saving device comprises a valve body (1), an air inlet connector (2), an air outlet mouth (3), a pressure reducing device and a flow control device. The pressure reducing device is arranged on the upper portion of the valve body (1) and is connected with an air inlet hole. Air currents flow in through the air inlet connector (2). An inner cavity of the valve body (1) is provided with three air cavities which are an air cavity A, an air cavity B, and an air cavity C. The medical oxygen saving device is characterized in that an air inlet end and an air outlet end are respectively provided with an inducting device controlling air inflow and an inducting device control air outflow. According to the medical oxygen saving device, flow of oxygen supply can be designed to be a convenient and quick stepping switch according to different flow requirements, and oxygen with different flow can be provided. The two air current inducting devices composed of membranes and springs are arranged, and air gaps of the cavities are reasonably set so that oxygen supply can be stopped at exhaling time and be started at inhaling time, and therefore oxygen is saved. Oxygen of the same volume can be prolonged by 2-3 times in utilization time, and the oxygen can be saved by more than 60%.
Description
Technical field
The present invention relates to medical instruments field, a kind ofly specifically use oxygen and with the oxygen output device of decompression for the saving of medical oxygen uptake process.
Background technology
Present oxygen inhalation apparatus is all at the uniform velocity to export gas, inserts the nostril oxygen supply through oxygen catheter.And in the process of patient respiration, when air-breathing, oxygen can be absorbed and used, and when exhaling, oxygen is also being exported always, has mostly wasted.In order to improve oxygen uptake efficient, also have and adopt the mask oxygen-inspiration method, but increased respiratory resistance after wearing, during expiration, carbon dioxide is discharged restrictedly, and therefore the patient can feel under the weather.
Summary of the invention
The objective of the invention is to solve the defective of above-mentioned prior art, reduce waste of oxygen, improve oxygen uptake efficient.
Technical scheme of the present invention is on the basis of existing oxygen regulator, at inlet end and outlet side, a diaphragm and spring to be set respectively, by place's diaphragm control inlet end diaphragm of giving vent to anger.When the outside is air-breathing, form negative pressure, first open the outlet side diaphragm, then the pressure due to inside reduces, and opens the inlet end diaphragm, thus output oxygen; When internal pressure is reduced to less than the counteracting force of outlet side spring, will close the outlet side diaphragm, internal pressure is increased, under the combined effect of inlet end spring force and pressure, close the inlet end diaphragm, thereby stop exporting oxygen.Outside exhalation process can accelerate to stop this process of air feed.
The invention has the beneficial effects as follows, the gas of same capacity can extend working time 3-5 times more than, has greatly reduced waste, has greatly improved oxygen uptake efficient.
Description of drawings
Fig. 1 is structural representation of the present invention
The specific embodiment
When reaching balance by distance between inlet suction port 1, valve pillar 2 and relief spring 3, gases at high pressure are converted to the low pressure input, low-pressure gas divides lead to fixedly Continuous Flow metering-orifice at three the tunnel: one, if gear just switches to this hole, outlet nozzle 4 is exported continuous flows, be not save oxygen when this grade, not so this gas circuit is blocked; Two lead to an air cavity A, and spring 5 is arranged in the bottom and a diaphragm 7 is sealed centre bore to jacking block 6 and air cavity B separates, and air cavity A communicates with outlet nozzle 4 by flow rate disc 8; Three lead to air cavity B through a micropore; Air cavity B communicates with atmosphere by a micropore, and this place is separated air cavity B by another diaphragm 9 and spring 10 with atmosphere.Formed simultaneously air cavity C, air cavity C communicates with outlet nozzle 4.When outlet nozzle 4 was air-breathing, air cavity C formed negative pressure, and diaphragm 9 is opened, and air cavity B and atmosphere are connected, and gas reduces and forms again negative pressure, and diaphragm 7 is opened, and by flow rate disc, the size of adjust flux outputs to outlet nozzle to gas, is sucked by patient from air cavity A; When the pressure of air cavity B was reduced to a certain degree, under the effect of the power of spring 10, diaphragm 9 up closedtop was lived micropore, blocking air cavity B communicates with atmosphere, air cavity B pressure raises, and diaphragm 7 is lived in pore in the effect lower seal of the power of air cavity pressure and spring 5, and outlet nozzle 4 has held one's breath.The carrying out that outside expiration can be accelerated this process.Along with going round and beginning again of breathing, this circulation is also constantly carried out, thereby reaches the function of joint oxygen.
