Problems solved by technology
[0003] Existing medicinal aerosols do not have a counting function, and patients cannot predict the amount of medicine used and the remaining medicine when using the product, which can easily lead to life-threatening or unnecessary troubles
For example, the appearance of traditional asthma spray cans cannot tell the amount of remaining medicine. If the patient has prepared multiple bottles of asthma spray cans, it can still solve the urgent need. If the patient does not prepare extra bottles of asthma spray cans, there is no one else around Once an asthma attack occurs, the patient may not be able to save himself by using the asthma spray can with no medicine in it, and is more likely to miss the prime time for emergency treatment, resulting in death accidents

The invention discloses a quantitative dosing actuator device enabling inverted spray assembly. The quantitative dosing actuator device is characterized in that the quantitative dosing actuator device includes an actuator body; an accommodating cavity is arranged in the actuator body; an aerosol can is arranged in the accommodating cavity; the aerosol can is provided with a universal quantification valve which is capable of quantitative dosing; one end of the actuator body is provided with a medicine liquid nozzle mechanism; the medicine liquid nozzle mechanism is connected with the universal quantification valve; and a counter which can count the number of times of medicine spray of the medicine liquid nozzle mechanism is arranged in the actuator body. The objective of the invention is to eliminate defects in the prior art. The quantitative dosing actuator device has the advantages of simple structure, convenient use as well as being safe and reliable, and can calculate the number of times of medicine spray.
Description
technical field [0001] The invention relates to a dosing actuator device assembled by reverse spraying. Background technique [0002] The metered dose aerosol actuator is an important part of the metered dose aerosol product, its main function is to carry the main body of the aerosol and open the valve of the aerosol, and at the same time open the contents of the drug according to the predetermined form It is sprayed into the throat of the mouth, and the drug particles of appropriate size directly act on the patient's lungs through the throat. [0003] Existing medicinal aerosols do not have a counting function, and patients cannot predict the amount of medicine used and the remaining medicine when using the product, which can easily lead to life-threatening or unnecessary troubles. For example, the appearance of traditional asthma spray cans cannot tell the amount of remaining medicine. If the patient has prepared multiple bottles of asthma spray cans, it can still solve t...
