While the medicine in the atomizing core 320 is atomized, the medicine in the storage cartridge 210 is continuously replenished into the atomizing core 320 through the minute holes of the piercing member 310, and the medicine is continuously administered.
Further, a temperature sensor is disposed on the atomizing core 320, and the temperature sensor is electrically connected to the control mechanism 400. The temperature sensor is capable of measuring the temperature of the atomizing core 320 and feeding back to the control mechanism 400. The control mechanism 400 controls the amount of current flowing through the heating member 330 based on the feedback result of the temperature sensor, thereby controlling the amount of heat generated by the heating member 330.
Referring to fig. 12, in addition, considering that the first housing 110 where the heating element 330 is located is detachably connected to the second housing 120 where the control mechanism 400 is located, the heating element 330 is provided with a conductive contact 331, and the control mechanism 400 is provided with a conductive contact 410.
When the first housing 110 is connected to the second housing 120, the conductive contact 331 contacts the conductive contact 410, thereby electrically connecting the heating member 330 to the control mechanism 400.
In addition, the conductive contacts 331 and the wire contacts are magnetically attracted to ensure stability of the connection of the heating member 330 and the control mechanism 400.
Specifically, the control mechanism 400 includes a power supply, a controller, and a respiration monitoring unit. The power supply supplies power to the heating element 330 under the control of the controller, and the temperature sensor is electrically connected to the controller. In addition, breathe the monitoring unit and be connected with the controller electricity, breathe the monitoring unit and can discern patient's respiratory state to in time feed back to the controller.
In the present embodiment, the respiration monitoring unit employs any one of an airflow sensor, a barometric pressure sensor, a vibration sensor, and a microphone sensor.
In a word, the above medicine atomizing device adopts the water-absorbing ceramic with a microporous structure as the atomizing core 320, so that the medicine can be in a dispersed state in advance. On the basis, the heating element 330 heats the atomizing core 320, so that the medicine in the atomizing core 320 is atomized, and liquid drops with nanometer particle size can be obtained, thereby meeting the requirement of deep-layer medicine application in the lung.
In addition, the sealing membrane 220 covering the liquid outlet is always fixedly connected with the storage chamber 210 during the administration process, and the medicine in the storage chamber 210 is led out by the puncture piece 310 puncturing the sealing membrane 220. The sealing film 220 is used for replacing movable parts such as valves and the like and is fixed on the storage bin 210 in a gluing or welding mode, so that the requirement of the medicine storage mechanism 200 on the sealing performance is more easily met, and the manufacturing difficulty of the medicine storage mechanism 200 is reduced.
