Abstract
A controlelr for oxygen therapy is composed of an inspiration-expiration detecting controller, nasal inspiration-expiration sensor, inspiration-expiration recognizing control, electrically controlled valve with inlet communicated to oxygen source, and oxygen delivering tube connected between the outer of said valve and nostril of patient.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of oxygen therapy controller that is used for to sufferer oxygen therapy.
Background technology
Oxygen uptake is the important means that the patient is rescued and treats.Correctly and effectively oxygen uptake is a rescue patient life, improves one of patient's survival rate and key factor of quality of life.People have designed many oxygen inhalers, respirator (or saying oxygen therapy device) for this reason.
People's breathing can be divided into expiration phase and intake period, and both time ratios are 3: 1.The oxygen therapy of expiration phase is invalid, only just can make oxygen enter alveolar in intake period oxygen therapy, combines with hemoglobin in the blood, thereby is input to systemic cell.The shortcoming of existing oxygen inhaler is in expiration phase and omnidistance oxygen therapy of intake period, phase and the intake period of promptly exhaling be all in oxygen therapy, and not only 75% waste of oxygen also hinders the expiration phase to exhale.Reason is that alveolar is moistening when exhaling, and warm gas has the effect of protection nasal mucosa, even inflammation occurs, and long-time continual oxygen therapy can make mucosa drying, hemorrhage.
Summary of the invention
Task of the present invention is the defective that will solve existing waste oxygen in the present oxygen therapy process, hinder expiration, designing a kind of may command oxygen therapy process opens oxygen, expiration phase in intake period and closes oxygen, thereby both saved oxygen, do not hindered the oxygen therapy controller of expiration again.
The technical scheme that realizes the object of the invention is:
A kind of oxygen therapy controller, it is characterized in that it contains an air-breathing/expiration detection control apparatus, be connected with one with this device by lead and be used for detecting the pick off that the nostril is air-breathing or exhale, be provided with air-breathing in the control device or the expiration recognition control circuit, be connected with an electrically-controlled valve with this control circuit, the air inlet of electrically-controlled valve is used for linking with source of oxygen, and the gas outlet of electrically-controlled valve is used for linking to each other with the inlet end of oxygen delivery tube, and the outlet side of oxygen delivery tube is inserted in oxygen uptake patient's nasal cavity.
Specifically, pick off is a critesistor, in the described air-breathing or expiration recognition control circuit temperature controller is arranged, and it links to each other with described electrically-controlled valve, opens or closes source of oxygen according to the temperature difference air-breathing or that exhale.
By such scheme as can be known; Utilize the present invention to control oxygen therapy, when air-breathing, oxygen is connected, normal oxygen therapy; Then oxygen shutoff during expiration.So, conserve oxygen (75%) in a large number not only, the warm also wettable alveolar of gas during expiration, the protection nasal mucosa avoids occurring inflammation, prevents mucosa drying that long-time continual oxygen therapy causes, hemorrhage.
Below in conjunction with accompanying drawing, the present invention is further described.
Description of drawings
Fig. 1 is an organigram of the present invention.
The specific embodiment
Embodiment:
A kind of oxygen therapy controller comprises an air-breathing/expiration detection control apparatus 1; Being connected with one with this device by lead 2 and being used for detecting the temperature sensor 3 that the nostril is air-breathing or exhale, can be to the sensitive critesistor of thermotonus specifically, can certainly be other temperature-sensitive element.Be provided with air-breathing in the control device 1 or the expiration recognition control circuit, as comparing amplifying circuit, gauge tap circuit, drive circuit etc.Be connected with an electrically-controlled valve 4 with control circuit, the air inlet 5 of electrically-controlled valve 4 is used for and source of oxygen (as oxygen cylinder, oxygenerator) links, and the gas outlet 6 of electrically-controlled valve 4 is used for linking to each other with the inlet end of oxygen delivery tube, and the outlet side of oxygen delivery tube is inserted in oxygen uptake patient's nasal cavity.The nasal cavity temperature is lower when air-breathing, near outside air temperature; The nasal cavity temperature is higher during expiration, near body temperature.The present invention is exactly the temperature difference of utilizing both, opens or closes source of oxygen by critesistor and air-breathing/expiration detection control apparatus 1, thereby saves oxygen when realizing gas transmission, does not hinder again and the purpose that helps exhaling.
Claims (2)
1, a kind of oxygen therapy controller, it is characterized in that it contains an air-breathing/expiration detection control apparatus (1), be connected with one with this device by lead (2) and be used for detecting the pick off (3) that the nostril is air-breathing or exhale, be provided with air-breathing in the control device (1) or the expiration recognition control circuit, be connected with an electrically-controlled valve (4) with this control circuit, the air inlet (5) of electrically-controlled valve (4) is used for linking with source of oxygen, the gas outlet (6) of electrically-controlled valve (4) is used for linking to each other with the inlet end of oxygen delivery tube, and the outlet side of oxygen delivery tube is inserted in oxygen uptake patient's nasal cavity.
2, according to the described oxygen therapy controller of claim 1, it is characterized in that described pick off (3) is a critesistor, in the described air-breathing or expiration recognition control circuit temperature controller is arranged, it links to each other with described electrically-controlled valve (4), opens or closes source of oxygen according to the temperature difference air-breathing or that exhale.
