Nebulization device and method capable of automatically recognizing frequency points of different mesh sheets

Abstract

The invention discloses a nebulization device capable of automatically recognizing frequency points of different mesh sheets. The nebulization device comprises a main unit cup with a cavity. A mainboard control panel is arranged in the cavity of the main unit cup and comprises a single-chip microcomputer module, a power management circuit module and a drive circuit module, wherein the power management circuit module and the drive circuit module are connected with the single-chip microcomputer module, and the drive circuit module is connected with the power management circuit module and mesh sheets. The mainboard control panel further comprises a battery module connected with the power management circuit module and the single-chip microcomputer module. The single-chip microcomputer module is used for generating high-frequency signals and converting external voltage signals into digital signals through an AD acquisition circuit; the power management circuit module is used for adjusting the voltage of the battery module into needed working voltage; the drive circuit module is used for amplifying the high-frequency signals generated by the single-chip microcomputer module and driving the mesh sheets to vibrate through a transformer. The invention further discloses a method capable of automatically recognizing frequency points of different mesh sheets. By means of the method, the mesh nebulization device can determine the working frequency points of different types of nebulization mesh sheets through scanning.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an atomization device and method for automatically identifying frequency points of different mesh sheets in the field of atomization therapy. Background technique [0002] With the continuous promotion of nebulizer inhalation therapy in various hospitals, the demand for nebulizers in the market is increasing. The current mainstream nebulizers include medical ultrasonic nebulizers and compression nebulizers. Among them, the traditional ultrasonic nebulizer is relatively bulky, and due to the heat generated during use, there are restrictions on nebulizing drugs. The compressed air nebulizer has become the mainstream product in the nebulizer market due to its simple structure and good drug adaptability. [0003] The mesh nebulizer is a new generation of nebulizer product developed based on the principle of ultrasonic nebulizer. It uses ultrasonic resonance to make the l...

Problems solved by technology

Once the working frequency of the mesh atomizer exceeds the fixed frequency error range, the atomizer will not vibrate at the optimal frequency, the current will increase, and the power consumption will increase; the spray rate cannot be guaranteed, and production inspection is required make very strict screening

In terms of after-sales service in the market, if the customer needs to replace the mesh atomizer, the manufacturer must replace it with a mesh atomizer of the same specification. If the mesh atomizer of other frequency points is misused, it may cause the customer Fixed-frequency nebulizer does not work properly

[0005] In recent years, as the market share of mesh nebulizers continues to increase, there are more and more mesh atomizers of different materials from different suppliers, and the existing atomizers cannot adapt to mesh fog at different frequency points. In the production process, for a mesh atomization device with a fixed frequency point, a large number of mesh atomization sheets that are not within the error range will inevitably be screened out, which will bring waste to the enterprise and increase production costs; The hole atomizing sheet is a consumable item. If it is replaced, it must be replaced together with the main unit of the atomization device. Replacing the mesh atomizing sheet alone may cause the risk of mismatching frequency points, and the power consumption of the machine will increase; the spray rate will not be equal. abnormal situation
