Abstract

The invention discloses an active inhalation drug delivery device system optimization method based on MEMS. The active inhalation drug delivery device system optimization method comprises a liquid medicine box, an oil guide plate, a porous liquid guide block, an atomization chip, a base, a PCB and a suction nozzle, the oil guide plate is provided with at least one liquid guide hole, the porous liquid guide block is mounted below the liquid guide hole, the base is provided with two through holes, and metal electrodes are arranged in the through holes. A metal electrode comprises an upper metal electrode, a lower metal electrode and a spring, one end of the spring is fixedly connected to the upper metal electrode, the other end of the spring is fixedly connected to the lower metal electrode, a contact on the upper metal electrode abuts against a resistance wire on the atomization chip, and the lower metal electrode abuts against a connecting column of the PCB. A first aerosol channel is arranged on the base, the suction nozzle is installed on the base, a second aerosol channel is arranged in the suction nozzle, and the second aerosol channel communicates with the first aerosol channel. According to the active inhalation drug delivery device system optimization method based on the MEMS, the problem of deformation or fragmentation of partial structure on an MEMS atomization core or chip can be solved.

Description

technical field [0001] The invention relates to the field of MEMS medical technology, in particular to a system optimization method for an active inhalation drug delivery device based on MEMS. Background technique [0002] At present, with the diversification of life and the aggravation of environmental pollution, respiratory diseases have become common diseases, such as asthma and chronic obstructive pulmonary disease, and the number of patients is still increasing. Generally, chronic respiratory diseases require long-term treatment, and the choice of treatment method is very important. Existing studies have shown that inhalation administration is the most simple and effective route of administration for the treatment of respiratory diseases such as asthma and chronic pulmonary obstruction. [0003] Inhalation therapy is a method in which the medicinal liquid is atomized to form an aerosol, and the patient inhales to complete the treatment. The aerosol of the medicinal li...
