Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a multifunctional anti-backflow ultrasonic atomization sheet and a multifunctional atomization device. Background Art

[0002] Atomization therapy mainly refers to aerosol inhalation therapy. An aerosol refers to tiny solid or liquid particles suspended in the air. Therefore, aerosol inhalation therapy uses an atomization device to disperse a drug into tiny mist droplets or particles, making them suspended in a gas and entering the respiratory tract and lungs to humidify the airway and treat respiratory tract inflammation. However, when existing atomization devices are in use, affected by the patient's breathing, drug mist will flow back, thus affecting the drug uptake during the next inhalation and reducing the atomization therapy effect. Summary of the Invention

[0003] The present invention provides a multifunctional anti-backflow ultrasonic atomization sheet and a multifunctional atomization device. By means of a blower, the pressure of the drug mist in the atomization tube is increased, thereby overcoming the influence of the pressure change in the atomization cover on the mist outlet state of the atomization hose and effectively avoiding the backflow of the drug mist.

[0004] To achieve the above object, the present invention provides the following technical solution: A multifunctional anti-backflow ultrasonic atomization sheet and a multifunctional atomization device, which include: a device main body, a horizontal positioning table is provided at the top of the device main body, a vertical bracket is provided on one side of the positioning table, and a controller is provided on the side of the bracket away from the positioning table; an atomization bottle, the atomization bottle is adapted to be placed on the positioning table, and a bottle cap is fitted on the top. An ultrasonic atomization sheet extending into the interior of the atomization bottle is provided at the bottom of the bottle cap, a ventilation pipe and a mist outlet pipe communicating with the ultrasonic atomization sheet are provided at the top, and the ultrasonic atomization sheet is electrically connected to the controller; a blower, the blower is fixedly arranged on the top of the bracket, and the air inlet of the blower is communicated with the mist outlet pipe, the air outlet of the blower is connected with an atomization hose, and the blower is electrically connected to the controller; an atomization cover, the atomization cover is provided with an air inlet and an air outlet, and the air inlet is communicated with the atomization hose.

[0005] Preferably, an electric heating plate is provided inside the device main body corresponding to the bottom of the positioning table, the electric heating plate is electrically connected to the controller, and a first one-way valve is provided in the mist outlet pipe.

[0006] Preferably, it further includes a circulation pump, the circulation pump is arranged at the bottom of the bracket, and the air inlet of the circulation pump is communicated with the air outlet through a first three-way joint, and the exhaust port of the circulation pump is communicated with the atomization hose through a second three-way joint; and a second one-way valve is provided at the second three-way joint corresponding to the circulation pump; the circulation pump is electrically connected to the controller.

[0007] Preferably, the ventilation pipe is connected to a pressurization pipe, and the pressurization pipe is connected to the exhaust port of the circulation pump through a third three-way joint.

[0008] Preferably, a filter is further included, and the filter is connected in series on the pressurization pipe.

[0009] The beneficial effects of the present invention are as follows: The device main body and the bracket are used to fix the atomization bottle, and the atomization bottle contains the liquid medicine for atomization. After the bottle cap is fastened, the ultrasonic atomization sheet contacts the liquid medicine, and under the action of the controller, the liquid medicine is atomized and discharged outwards through the atomization pipe. At the same time, the controller starts the blower, and the blower pressurizes the medicine mist discharged from the atomization pipe and sends it into the atomization hood through the atomization hose for the patient to inhale. During this process, the blower increases the pressure of the medicine mist in the atomization pipe, thereby overcoming the pressure change during the patient's breathing process and effectively avoiding the backflow of the medicine mist. The electric heating plate heats the liquid medicine in the atomization bottle under the action of the controller. On the one hand, it increases the temperature of the liquid medicine, making the atomization efficiency of the liquid medicine higher. On the other hand, it also increases the temperature of the medicine mist, improving the patient's inhalation comfort. The circulation pump circulates the gas in the atomization hose and the atomization hood, increasing the flow rate of the medicine mist in the atomization hose while reducing the influence of the pressure change in the atomization hood on the mist outlet state of the atomization hose. The filter filters the medicine-containing gas pumped by the circulation pump and sends it into the atomization bottle through the ventilation pipe, thereby avoiding the generation of negative pressure in the atomization bottle and improving the mist outlet efficiency.
