Problems solved by technology

[0002] Ultrasonic nebulizer is a kind of ultrasonic atomizer that uses ultrasonic directional pressure to make the surface of the liquid bulge, and cavitation occurs around the raised liquid surface, so that the liquid is atomized into an aerosol of small molecules, so that the drug molecules can directly enter the capillaries or alveoli through the aerosol. , to achieve the therapeutic effect of equipment, suitable for colds, allergic rhinitis, nasal congestion, without heating or adding any chemical reagents, to achieve the purpose of auxiliary treatment; the medical ultrasonic nebulizer is always in a continuous working state, and the user only has The atomized medicinal liquid is inhaled into the respiratory system when inhaling, and the excess atomized medicinal liquid can only flow out directly from the exhaust port when exhaling, which not only directly causes waste of medicinal liquid, but the medicinal liquid flowing out of the exhaust port It will irritate the eyes and other sensitive organs of the human body, and will also cause certain pollution to the environment.
Those skilled in the art are also constantly trying to improve, but this problem has not been solved very well

Embodiment 1

[0016] see figure 1 — Figure 4 , a medical ultrasonic atomizer with suction induction intermittent air supply, the atomizer includes an atomizer shell 1, a medicine cup 2, an air supply fan 3, a transformer 11, A liquid level sensor 12, a control valve 4 and a CPU logic control circuit 5, the atomizer housing 1 is connected to the inhalation mask 7 through a pipeline 6, and a pressure / flow sensor 8 is arranged in the pipeline 6 leading into the inhalation mask, The control valve 4 is a solenoid valve or a one-way stop valve. An atomization volume adjustment switch 10 and an atomization concentration adjustment knob 9 are arranged on the atomizer shell. The function of the atomization amount adjustment switch is to adjust the oscillation amplitude of the atomization sheet, so as to achieve the function of adjusting the atomization amount, and it has the function of a power switch, the atomization concentration adjustment knob, and the adjustment knob can adjust the size of t...

Embodiment 2

[0018] see figure 1 , figure 2 , the use method of the medical ultrasonic nebulizer with suction induction intermittent air supply, the user's inhalation and exhalation will directly affect the pressure and flow rate of the air flow in the pipeline of the air supply channel of the nebulizer, and in the pipe of the air supply channel A pressure / flow sensor is installed in the road, and the sensor sends the sensed pressure or flow signal to the amplifying circuit with logic function or CPU logic control circuit, and the amplifying circuit with logic function or logic control circuit directly controls the speed or flow rate of the air supply fan. Air channel control valve switch.

[0019] How it works: see figure 1 — figure 2 , with inhalation induction intermittent air supply medical ultrasonic nebulizer The specific implementation method: add a pressure / flow sensor 5 in the pipeline of the nebulizer close to the inhalation mask, and the CPU logic control circuit will autom...

Abstract

The invention relates to an intermittent air supply type medical ultrasonic nebulizer with inspiration induction. The intermittent air supply type medical ultrasonic nebulizer is characterized in that the nebulizer comprises a nebulizer housing. A medicine glass, an air supply fan, a control valve and a CPU logic control circuit are arranged in the nebulizer housing. The nebulizer housing is connected with an inhalation mask through a pipe, and a pressure / flow sensor is arranged in the pipe led into the inhalation mask. According to the technical scheme of the nebulizer, the overall structural design is ingenious, and it is ensured that only a small amount of nebulization medicine liquid flows out of an exhaust port in the process that a user uses medical ultrasonic normally.

Description

technical field [0001] The invention relates to an atomizer, in particular to a medical ultrasonic atomizer with suction induction intermittent air supply, belonging to the technical field of medical equipment. Background technique [0002] Ultrasonic nebulizer is a kind of ultrasonic atomizer that uses ultrasonic directional pressure to make the surface of the liquid bulge, and cavitation occurs around the raised liquid surface, so that the liquid is atomized into an aerosol of small molecules, so that the drug molecules can directly enter the capillaries or alveoli through the aerosol. , to achieve the therapeutic effect of equipment, suitable for colds, allergic rhinitis, nasal congestion, without heating or adding any chemical reagents, to achieve the purpose of auxiliary treatment; the medical ultrasonic nebulizer is always in a continuous working state, and the user only has The atomized medicinal liquid is inhaled into the respiratory system when inhaling, and the exc...
