The designed oxygen humidifier of this utility model is opened oxygen cylinder or is connected central oxygen supply system in application process, and oxygen is taken into account air chamber enters nebulizer through connection tube air inlet by flow.Connect the power supply of circuit control panel, will be full of distilled water in the water connection tube, the heater that is positioned at the water storage bottle heats water.Electromagnetic valve is opened at interval automatically, and the distilled water in the water storage bottle enters by the water connection tube in the housing of aerosol apparatus, and after the intravital distilled water of shell reached predefined value, electromagnetic valve cut out automatically.The air inlet of oxygen by nebulizer enters in the nozzle in the nebulizer, spray orifice by upper end of nozzle, oxygen mixes the intravital water of shell with formation water smoke from water channel sucking-off and oxygen, water smoke stops through spray orifice top baffle plate, big particle water comes back in the housing, make that contained particle water is suitable for the human body needs in the water smoke, water smoke enters in the snakelike corrugated tubing by outtake tube, and the "T"-shaped pipe by snakelike corrugated tubing and patient airway place enters patient's gas port.The temperature sensor that is provided with on the "T"-shaped pipe of patient airway mouth will enter the temperature transfer of water smoke in the patient airway and give circuit control panel, and when temperature was low, the heater in the water storage bottle continued heating; When temperature was higher, heater quit work.After a period of time, when the intravital water of nozzle housing used up, electromagnetic valve was opened automatically, water-filling in the housing of nozzle, reach a certain amount of after, electromagnetic valve cuts out automatically.Electromagnetic valve can regularly start, and interval is set in advance by operator, and can regulate at any time as the case may be, thereby realizes the adjustable of humidifying degree.The oxygen flow of system can be regulated by flow-limiting valve.If no flow-limiting valve can make upper and lower the moving of baffle plate of spray orifice by regulating the outtake tube in the nozzle, regulate oxygen flow by the gas output of retaining plug control spray orifice.If do not have nebulizer in the oxygen humidifier, then oxygen enters air inlet pipe by effusion meter, stop by needle valve in air inlet pipe and water storage bottle air inlet junction, form tiny spray orifice, air-flow with water from water pipe that the air inlet pipe sidewall is linked up mutually in sucking-off, mix back formation water smoke enters in the internal layer water storage bottle with gas, big particle water sinks to getting back in the internal layer water storage bottle, the dampness and the water smoke of the heat of outer water storage bottle evaporation are mixed, pass to the "T"-shaped pipe of patient airway from the connection tube of sidewall, moistening gas enters the patient airway mouth, and air inflow can be regulated by needle valve.
The operation principle of the circuit of the oxygen humidifier that this utility model is designed is: when work, and energized, the critesistor (R in the temperature control circuit 1) measure the temperature of "T"-shaped pipe place gas in the patient airway, when temperature lower, critesistor (R 1) the resistance rising, power component (SCR) conducting, heater (AB) continues heating, the temperature of water in the water storage bottle is raise, thereby improve the temperature that enters gas in the patient respiration road; After gas temperature in entering the patient respiration road raises, critesistor (R 1) the resistance reduction, when being reduced to certain value, not conducting of power component (SCR), heater (AB) stops heating, the temperature of water in the water storage bottle is remained in certain temperature range, regulate the gas temperature that enters in the patient respiration road automatically, keep constant intake air temperature by temperature control circuit.The homoiothermic resistance R 4Can select temperature, temperature is controlled in 40 ℃~100 ℃ scopes.After the energized, power circuit conducting in the control circuit of electromagnetic valve, to battery (E) charging, meanwhile, the light emitting diode (D of power supply indication 3) bright, time base circuit work is controlled audion (T) conducting and is ended, and when audion (T) conducting, electromagnetic valve (L) is opened, water connection tube or water pipe conducting, after a period of time, audion (T) ends, and electromagnetic valve (L) cuts out, water connection tube or not conducting of water pipe.The time that electromagnetic valve (L) opens and cuts out can be regulated, and can regulate the moistening degree of oxygen atomization.When the power failure phenomenon occurring, the backup battery in the circuit (E) can be powered and be continued holding circuit work, keeps the oxygen humidifier operate as normal.
Heater available metal resistance wire, PTC pottery, quasiconductor or other heating material in the designed oxygen humidifier of this utility model are made.Also can control automatically oxygen humidifier in addition by single-chip microcomputer.
Sometimes for increasing the content of moisture content in the mixed gas, also can in the water storage bottle of the designed oxygen humidifier of this utility model, put into existing filter paper support, place spiral type filter paper on the filter paper support, strengthen disengagement area, thereby increase the evaporation of water amount.
The advantage of the oxygen humidifier that this utility model is designed is:
1. simple in structure, compact, removed in addition additional atomization plant from.Oxygen is fast by the air velocity at spray orifice or needle valve place, forms negative pressure, in the water suction gas with heating, forms droplet, and bigger particle water falls after rise to nozzle or water storage bottle, makes fogdrop diameter As soon as possible Promising Policy humidifying needs.
2. humidifying is abundant, keeps the temperature of gas consistent with 32~35 ℃ of the temperature of needed by human body.Because the water in the oxygen humidifier keeps its stationary temperature by heater and control circuit; therefore it is close to enter water smoke and respiratory mucosa the person required temperature and humidity from oxygen humidifier; respiratory mucosa is well protected; guarantee when human body is received treatment, reduce the damage of lung and bronchial mucosa as far as possible.
3. use easyly, the patient who receives treatment is unrestricted.When using, because work process is controlled automatically by control circuit, the temperature of its humidified gas is carried out automatically and is regulated, and the water source replenishes automatically, does not therefore need the nurse by the special messenger, has alleviated medical personnel's burden; The connection tube that is connected with the patient respiration road adopts snakelike corrugated tubing, has guaranteed that nebulizer vertically places, and water wherein can be not excessive, and patient can normally stand up, and nursing is convenient.
4. convenient drug administration.The directly administration of existing oxygen humidifier, and the designed oxygen humidifier of this utility model can be by the drug delivery port administration at nozzle place or directly medicine is added in the water in the water storage bottle, when oxygen by spray orifice or needle valve place with the water sucking-off during with the mixed formation of oxygen fog, medicine in the water is also in the entrained gas, bring in the patient body by gas, therefore administration is easy, convenient, and is atomized medicine introducing.
The designed oxygen humidifier of this utility model is mainly used in hospital, also can be used for other special treatment place.
In addition, the bottle of the oxygen humidifier that this utility model is designed and the shape of other parts, relative position can be done suitable adjustment as required, with the requirement of satisfying processing and using.
