Spray hole optical batch detecting device and method for aerosol inhalation driver

Abstract

The present invention discloses a spray hole optical batch detecting device for an aerosol inhalation driver. The aerosol inhalation driver comprises a main body and a nozzle at one end of the main body; a spray hole for providing an aerosol is formed in the nozzle. The optical detecting device includes a light source, a camera and an image processing apparatus; the light source illuminates one end of the main body, wherein the one end of the main body is far away from the nozzle; the lens of the camera faces the spray hole; and the image processing apparatus processes a picture taken by the camera. According to the detecting device, the diameter of the spray hole is obtained by means of an optical mode and a photographing mode. The spray hole optical batch detecting device for the aerosolinhalation driver has the advantages of simple and convenient operation, high accuracy of acquired data and the like.

Description

technical field [0001] The invention belongs to the processing field of aerosol inhalation drug dispensers, and in particular relates to an optical batch detection device and method for nozzle holes of an aerosol inhalation driver. Background technique [0002] As air pollution becomes more and more serious, the number of patients suffering from respiratory diseases at home and abroad is increasing day by day, and medicines for the respiratory system have gradually entered the field of vision of pharmaceutical companies, doctors and patients. Asthma (Asthma) and chronic obstructive pulmonary disease (Chornic Obstructive Plumonary Disease, COPD) are the two major respiratory diseases that have the most serious impact on patients. Statistics from the World Health Organization in 2013 show that respiratory diseases have jumped to the third highest fatality rate diseases, the mortality rate is as high as 14.09%. However, with the great development of new technology in pulmonary...

Problems solved by technology

However, this detection method cannot accurately judge the roundness of the small hole and the surface defect of the small hole. It may also be due to the poor accuracy of the detection equipment, which leads to inaccurate or wrong measurement results.

If the small hole is not a complete circle or there are burrs around it, it may cause the medicine to be sprayed out of the prescribed dose or direction when spraying, which will affect the droplet distribution data of the medicine, affect the quality of the medicine, and cause differences to patients. degree of potential harm

[0005] In addition, the existing airflow batch detection method needs to provide more proprietary auxiliary equipment such as air pressure source, which increases the consumption of various resources such as production site and energy by the system, which is also one of the main shortcomings of this method.
