Intelligent reminding effective aerosol inhalation device for internal medicine nursing

Abstract

The invention discloses an intelligent reminding effective aerosol inhalation device for internal medicine nursing. The device comprises a frequency acquisition circuit, a feedback comparison circuitand a filtering emission circuit. The frequency acquisition circuit is used for acquiring analog signal frequency of a controller in the internal medicine nursing intelligent reminding effective aerosol inhalation device. The feedback comparison circuit uses a triode Q1 and a triode Q2 to form a push-pull circuit to prevent signal crossover distortion. Meanwhile, an operational amplifier AR1, a diode D2 and a diode D3 are used for forming a mean value detection circuit to extract mean value signals in signal waveforms, an operational amplifier AR4, a capacitor C4, a capacitor C5 and a capacitor C9 are used for forming a frequency selection circuit to limit the signals, and a capacitor C7, a capacitor C8 and resistors R16-R16 are used for the filtering transmitting circuit. And a resistor R18 forms a filter circuit to filter signal clutters, and the signal clutters are sent to a remote monitoring platform of the aerosol inhalation device through a signal emitter E1, so that the performance of the internal medicine nursing intelligent reminding effective aerosol inhalation device is guaranteed.

Description

technical field [0001] The invention relates to the field of circuit technology, in particular to an intelligent reminder and effective atomization inhalation device for internal medicine nursing. Background technique [0002] At present, the atomization inhalation method uses high-speed oxygen gas flow to make the liquid medicine into a mist shape, and then inhales it through the respiratory tract to achieve the purpose of treatment. The speed of the high-speed oxygen flow and the nebulization rate signal of the drug liquid can be adjusted in time according to the physiological condition of the patient to improve the efficiency of nebulization inhalation, while the nebulization rate signal received by the controller of the nebulization inhalation device will change from time to time during collection. As a result, the nebulization inhalation device controller receives the nebulization rate signal purely with a delay, resulting in errors in the adjustment of equipment parame...

[0002] At present, the atomization inhalation method uses high-speed oxygen gas flow to make the liquid medicine into a mist shape, and then inhales it through the respiratory tract to achieve the purpose of treatment. The speed of the high-speed oxygen flow and the nebulization rate signal of the drug liquid can be adjusted in time according to the physiological condition of the patient to improve the efficiency of nebulization inhalation, while the nebulization rate signal received by the controller of the nebulization inhalation device will change from time to time during collection. The nebulization inhalation device controller receives the nebulization rate signal due to pure delay, resulting in errors in the adjustment of equipment parameters by the nebulization inhalation device controller, which seriously affects the performance of the internal medicine nursing intelligent reminder and effective nebulization inhalation device
