Problems solved by technology

With this atomization method, the atomized particles are thicker and the drug inhalation rate is low
On the other hand, when the patient uses the above two nebulizers for nebulization treatment, during the exhalation phase, the drug particles cannot be inhaled by the patient, which is in a state of complete waste
In addition, no matter what kind of atomization generating equipment, there is a high purchase cost, and it is difficult to carry out atomization treatment at home.

Embodiment 1

[0044] The high performance mesh type atomizer of the present invention, its whole operation process is as follows:

[0045] The liquid medicine passes through the mesh atomizing sheet from the liquid medicine tank 1 to form liquid medicine particles with an MMAD value of 2-3 microns, and enters the mist storage tank body 3 through the communication hole 16 of the mist storage tank body. Since the base 4 of the mist storage tank body 3 has an inhalation check valve, the medicinal liquid particles will not escape from the mist storage tank body 3 . When the patient inhales, the exhalation one-way valve 8 on the mask joint 2 is tightly closed, and the drug particles are sucked out by the patient from the mist storage tank 3. At this time, the air pressure in the mist storage tank 3 decreases, and the base of the mist storage tank 3 The suction one-way valve of 4 is turned on, the external air enters the mist storage tank body 3, and the air pressure in the mist storage tank body...

Abstract

The invention provides a high-performance mesh atomizer, which belongs to the field of medical devices. The high-performance mesh atomizer includes a liquid medicine tank (1), and a liquid medicine cover (5) for closing the liquid medicine tank (1). ), mask connector (2), isolation plate, mist storage tank (3) and the base (4) detachably connected to the bottom of the mist storage tank (3), the liquid medicine tank (1) and the mask joint (2) Set on the isolation plate and detachably connected with the storage tank (3) through the isolation plate, the liquid medicine tank (1) can form the liquid medicine into liquid particles with MMAD value less than 5 μm and input them The spacer tank body (3) is inhaled by the patient through the mask connector (2). The high-performance mesh nebulizer provided by the invention is an atomization inhalation device suitable for atomization inhalation of children and adults. The device has the characteristics of high atomization inhalation rate, low working noise, low use cost, and high convenience.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a high-performance mesh type atomizer. Background technique [0002] At present, the domestic atomization market has great potential and maintains rapid growth every year, mainly because the atomization inhalation of drugs has the advantages of strong targeting, high bioavailability, and small side effects. [0003] At present, there are two main types of nebulizers used in medical institutions on the market, compressed gas nebulizers and ultrasonic nebulizers. The compressed gas atomizer uses the Venturi effect to atomize the liquid medicine by outputting high-pressure and high-speed airflow. The main disadvantage of this atomization method is that the atomized particles are uneven in thickness, the effective atomization inhalation rate is low, and the working noise is relatively large. Ultrasonic nebulizers use ultrasonic waves to atomize liquid medicine. In this...
