Description
Technical field
This utility model belongs to medical apparatus and instruments II class field.It is a kind of valving that is used on the medical oxygen uptake process oxygen inhalation apparatus.This valving is collection decompression, stepping metering oxygen supply, exhales and stop inhaling for saving three kinds of functions of oxygen supply the oxygen regulator that is one.
Background technology
The valve major function of present domestic oxygen inhalation apparatus is decompression and at the uniform velocity exports gas that the oxygen that is about to 15MPa pressure in oxygen station or the oxygen cylinder reduces pressure and is that 0.2-0.3MPa, flow set are the step-less adjustment output of 0-15l/min, oxygen supply at the uniform velocity continuously.This oxygen regulator is not quick to the adjusting inconvenience of different flow oxygen supply, and in human body oxygen uptake process, exhaling does not need oxygen, but owing to be continuous oxygen supply, can not stop oxygen supply when human body is exhaled, and oxygen supply this moment is wasted.Oxygen regulator is to realize exhaling stopping inhaling for the batch (-type) oxygen supply, to saving oxygen, prolongs oxygen cylinder and has decisive role service time.
Summary of the invention
To stop inhaling for the batch (-type) oxygen supply in order realizing exhaling, to prolong oxygen cylinder service time, this utility model provides a kind of medical joint oxygen actuator, and it is stronger to make it to reach reduced pressure capabilities, adapts to input pressure greater than 15-30MPa, and shuchuyali stabilizes to 0.2-0.3Mpa.
The technical solution of the utility model realizes in the following manner, medical joint oxygen actuator, comprise valve body, inlet suction port, outlet nozzle, decompressor and volume control device, be provided with on the decompressor on the top of valve body, air-flow enters from inlet suction port, and the inner chamber of valve body is respectively equipped with three air cavity A, B, C, and decompressor is located at the top of valve body, be connected with air inlet, it is characterized in that: the induction installation that described inlet end and outlet side respectively are provided with a control air inlet and give vent to anger.
Described inlet end induction installation is made up of a diaphragm and a spring.
Described outlet side induction installation also is made up of a diaphragm and a spring.
Described air cavity A is arranged on inlet end, and air cavity B and atmosphere link, and air cavity C communicates with outlet nozzle 4, and chamber A communicates with outlet nozzle 4 by flow dish 8.
Described decompressor comprises relief spring, decompression seat and valve pillar.
Described volume control device is to use cover cellular type flow dish to realize that the gas flow stepping accurately measures output.
This utility model, the flow of oxygen supply can be arranged to step switch easily and efficiently by different traffic demands, accurately confesses the needs of different flow oxygen.By airflow sensor device and the reasonable cavity airflow clearance of setting that two covers are made up of diaphragm and spring is set, realize exhaling and stop inhaling for saving oxygen.Can make the oxygen of same capacity, prolong 2-3 service time doubly, save oxygen and reach more than 60%.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model.
The specific embodiment
Know by Fig. 1, the medical joint oxygen actuator of present embodiment, comprise valve body 11, inlet suction port 1, outlet nozzle 4, decompressor and volume control device, be provided with on the decompressor on the top of valve body 11, air-flow enters from inlet suction port 1, and the inner chamber of valve body 11 is respectively equipped with three air cavity A, B, C, and decompressor is located at the top of valve body 11, be connected the induction installation that inlet end and outlet side respectively are provided with a control air inlet and give vent to anger with air inlet.Decompressor comprises relief spring 3, decompression seat and valve pillar 2.By inlet suction port 1, the gases at high pressure that will advance outward apart from balance between valve pillar 2 and the relief spring 3 transfer the low pressure input to.Air cavity A is arranged on inlet end, and air cavity B atmosphere links, and air cavity C communicates with outlet nozzle 4, and chamber A communicates with outlet nozzle 4 by flow dish 8.Low-pressure gas is by air cavity A, and bottom spring 5 and jacking block 6 are sealed centre bore with diaphragm 7, and B separates with air cavity, and air cavity A communicates with outlet nozzle 4 by flow dish 8.Low-pressure gas leads to air cavity B by a micropore simultaneously, and air cavity B communicates with atmosphere by a micropore, and the inlet end induction installation is made up of a diaphragm 7 and a spring 5.The outlet side induction installation also is made up of a diaphragm 9 and a spring 10.Because diaphragm 9 and spring 10 separate air cavity B with atmosphere, 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, air cavity B and atmosphere are connected, gas reduces and forms negative pressure again, and diaphragm 7 is opened, and gas is regulated the flow size from air cavity A by flow dish stepping, be input to outlet nozzle, be absorbed by the body.Reduce to a certain degree when the pressure of air cavity B, diaphragm 9 is upwards sealed micropore, blocks air cavity B and communicates with atmosphere, and air cavity B pressure raises, and diaphragm 7 is upwards sealed air inlet, and outlet nozzle 4 stops to give vent to anger.Along with renew the Tuesday of breathing, this circulation is constantly carried out.Thereby realized decompression, stepping metering oxygen supply.Exhale to stop inhaling and on an oxygen regulator, embody for saving oxygen supply three functions.Volume control device is to use cover cellular type flow dish to realize that the gas flow stepping accurately measures output.
This utility model has realized collecting three kinds of functions the technological break-through that is one, makes it to reach stronger in the decompression energy, adapts to the big 15-30MPa of input pressure, and shuchuyali stabilizes to 0.2-0.3MPa; The flow of oxygen supply can be arranged to step switch easily and efficiently by different traffic demands, accurately confesses different flow oxygen; Can stop oxygen supply during expiration, oxygen supply when air-breathing according to the frequency intermittent oxygen supply of human body respiration.According to medical statistics, the average per minute of human body respiration 20 times was breathed about 3 seconds at every turn, and wherein the time of Xiing is 1 second, and the time of exhaling is 2 seconds.Exhale with the ratio of inhaling be 1:2. Stop on the induction installation for exhaling in suction, at inlet end and outlet side the induction installation controlling air inlet and give vent to anger is set respectively, induction installation is made up of a diaphragm and spring.When human body is air-breathing, produce negative pressure, open the outlet side induction installation, after the outlet side induction installation was opened, the inner chamber body pressure between it and the inlet end reduced, and the inlet end induction installation is opened, oxygen enters volume control device from inlet end, import human body, when air-breathing stopping, negative pressure disappears, the outlet side induction installation cuts out, chamber pressure between it and the inlet end recovers, and the inlet end induction installation cuts out, and oxygen stops output.On volume control device, use two cover cellular type flow dish technologies, with different apertures different flows is set, regulate the different requirements of confessing a requisite oxygen amount of the every suction of human body.
