As an essential auxiliary instrument for maintaining breathing and ensuring ventilation of a respiratory failure patient, when a breathing machine assists breathing, gas delivered to an airway of the patient is mixed gas of oxygen and air, and the temperature and the humidity of the gas entering the airway of the patient are generally basically consistent with those of indoor air. The humidifier of the respirator is used for heating humidifying liquid (sterilization water for injection) to ensure that gas inhaled by a patient reaches sufficient temperature and humidity, so that the airway of the patient is protected, and the occurrence of ventilator-associated pneumonia is reduced.

At present, two ways are added to a humidification liquid of a clinical respirator: 1. the pipeline of the respirator is disconnected, the stopper of the sterilized injection water bottle is pried open, and the humidifying liquid is directly poured to the water level line and then connected with the pipeline. However, the support function of the breathing machine is lost when the pipeline is disconnected, and caution is needed to be taken for severe patients. When the humidifying liquid is consumed, the humidifying liquid is added according to the method, the liquid is added for one time in 2-3 hours generally, and the phenomenon of excessive water addition or dry burning often occurs when the work is busy, so that the temperature and the humidity of the gas inhaled by a patient are extremely unstable, the patient is easy to cause unsmooth sputum excretion and airway spasm, the discomfort of the patient is increased, and the humidifying liquid is easy to enter the breathing machine to damage elements. 2. The infusion apparatus is connected with the humidifying liquid to turn on the switch at regular time to supplement the humidifying liquid. The method keeps the tightness of the pipeline, is more beneficial to the principle of aseptic operation, has the defect that the phenomenon of excessive water addition or dry burning is easy to occur, and because a manual water addition mode is adopted, and the water addition process is intermittent injection, the condition of large water injection amount, small water injection amount and large water injection amount is easy to occur, and the humidifying effect is influenced by the water injection amount. Moreover, as the nurse is busy and has heavy workload, the switch of the infusion apparatus is often turned on, and the nurse forgets to turn off the infusion apparatus after adding water, so that the phenomenon that the humidification liquid is added with excessive water often occurs.

Be equipped with intake pipe 3 on cover 7, inlet tube 4, outlet duct 6, controller 10, 3 hypomere of intake pipe stretches into jar body 1 in, and be equipped with touch switch 11, play response touching effect, touch switch 11 includes touch switch and lower touch switch, be equipped with movable sleeve 19 on last touch switch and the intake pipe 3 between the touch switch down, be equipped with kickboard 12 on the movable sleeve, be equipped with brokenly bubble thorn 14 on kickboard 12 bottom surface, be used for pricking the gaseous bubble that gets into aquatic and produce, be provided with solenoid valve 5 on inlet tube 4, be equipped with humidity transducer 17 and temperature sensor 13 on the 7 medial surfaces of cover of outlet duct 6 both sides respectively. The ultrasonic atomizer 9 and the heater 18 are integrally installed on the base 2 and used for atomizing and heating the wetting liquid, and the heat insulation layer 20 surrounding the ultrasonic atomizer 9 and the heater 18 is arranged in the base 2, so that the base 2 can be prevented from generating heat when the heater 18 heats slightly. The humidity sensor 17, the temperature sensor 13 and the touch switch are in signal connection with the controller 10, and the ultrasonic atomizer 9, the heater 18 and the electromagnetic valve 5 are electrically connected with the controller 10.

The working principle of the utility model is as follows:

when in use, the water inlet pipe 4 is connected with the infusion tube, the pipeline of the respirator is respectively connected with the air inlet pipe 3 and the air outlet pipe 6, the sterilization injection water is added into the tank body 1 through the water inlet pipe 4, and the oxygen is input from the air inlet pipe 3 and is output from the air outlet pipe 6 after being humidified. In the process of continuously adding the sterilization water for injection, the water level gradually rises, the movable sleeve 19 floats upwards along the air inlet pipe 3 under the buoyancy action of the floating plate 12, when the movable sleeve 19 is in contact with the upper touch switch, the upper touch switch transmits a contact signal to the controller 10, and the controller 10 controls the electromagnetic valve 5 to be closed, so that the water inlet pipe 4 is closed, and the phenomenon of 'overflow' is avoided by ensuring that water cannot be injected continuously. In the process, the bubble-breaking pricks 14 on the bottom surface of the floating plate 12 can effectively pierce bubbles to stimulate water mist to oxygen, so as to increase the humidity in the oxygen. Along with the continuous work of the breathing machine, the water in the humidification tank is slowly reduced, the water level is gradually reduced, the movable sleeve 19 is slowly reduced along with the liquid level, and the movable sleeve 19 is separated from the upper touch switch; when the movable sleeve 19 descends to the lower touch switch and contacts with the lower touch switch, the lower touch switch transmits a contact signal to the controller 10, the controller 10 controls the electromagnetic valve 5 to be opened again, and then the water inlet pipe 4 is opened and water is injected continuously, so that the liquid level in the humidification tank is kept at a better height, and the danger of 'idle burning' of the humidification tank caused by too little humidification water is avoided. The humidifying tank is internally provided with a temperature sensor 13 and a humidity sensor 17 (arranged on the inner sides of the tank covers 7 at the two sides of the air outlet pipe 6), the temperature and the humidity of the air output by the air outlet pipe 6 are monitored, and relevant information is displayed on the display screen 8 in real time and is transmitted to the controller 10. When the temperature is higher, the controller 10 controls the heater 7 to stop heating; when the humidity is high, the controller 10 controls the ultrasonic atomizer 9 to stop atomizing. The display screen 8 is convenient for nurses to check the humidification tank.

Therefore, the utility model discloses can guarantee that exhaust oxygen humidity and temperature are moderate in the outlet duct 6, can improve the comfort level of patient at the oxygen therapy in-process, realize carrying out accurate control to output oxygen's humidity and temperature, stop that humidifying jar "overflow" or "dry combustion method" phenomenon takes place, improve the security that clinical machine ventilated, avoid serious medical malpractice to take place, also reduce medical personnel's work load.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the present invention is not limited by the appended claims.
