Description

Spraying agent leakage detection device

Technical Field

The utility model relates to a nebula production facility technical field, in particular to nebula leak hunting device.

Background

The spray is a preparation which is prepared by filling raw material medicines or proper auxiliary materials into a special device, releasing the content in the form of mist by means of pressure of a manual pump, high-pressure gas, ultrasonic vibration or other methods when in use, and is used for lung inhalation or directly sprayed to cavity mucosa, skin and the like. The propellant is different from aerosol, and the propellant is the power of the medicine sprayed by the aerosol, such as chlorofluoroalkane (which is not used at present), hydrofluoroalkane, dimethyl ether and the like.

After the spray is filled into a bottle, leakage detection is needed through leakage detection equipment, the problem that the product qualification rate is caused due to the fact that sealing is not tight can be avoided, and the existing leakage detection mode is a differential pressure color washing bath method. The rolled and covered spraying agent bottle is put into water with a color which is obviously different from that of the medicine and is placed for a period of time, then the medicine is taken out to see whether the colored water enters the medicine or not, and whether the medicine leaks or not is judged manually. This method has several disadvantages: 1. destructive testing, the packaging material and even the product can be contaminated. Even worse, drugs with minimal microleakage are not detected but have become contaminated; 2. low efficiency, long test period, complex process, and large amount of raw materials and manpower; 3. the probabilistic detection method is greatly influenced by color, concentration and environment, and is greatly influenced by the complexity of leakage channels and manual identification.
