Countable quantitative dosing actuator device with protecting cover

Abstract

The invention discloses a countable quantitative dosing actuator device with a protecting cover. The countable quantitative dosing actuator device with the protecting cover is characterized in that an actuator body is included, a containing cavity is formed in the actuator body, a spray tank is arranged in the containing cavity, and a monomeric universal quantitative valve which can achieve quantitative dosing is arranged on the spray tank; one end of the actuator body is provided with a liquid medicine nozzle mechanism which is connected with the monomeric universal quantitative valve, a counter which can count the spraying times of the liquid medicine nozzle mechanism is arranged in the actuator body, and the other end of the actuator body is provided with the safe protecting cover which can prevent mistakenly pressing. According to the countable quantitative dosing actuator device with the protecting cover, the defects in the prior art are overcome, and the countable quantitative dosing actuator device with the protecting cover is simple in structure, convenient to use, safe, reliable and capable of achieving quantitative dosing and counting the spraying times.

Description

technical field [0001] The invention relates to a countable dosing actuator device with a safety cover. 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] The existing quantitative drug delivery aerosol products generally have no safety protection measures, and the valve is easy to be opened by mistake when moving or transporting, posing potential safety hazards. At the same time, the existing medicinal aerosol has no 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-threat...

Problems solved by technology

[0003] Existing quantitative drug delivery aerosol products generally have no safety protection measures, and it is easy to open the valve by mistake when moving or transporting, posing safety hazards

At the same time, the existing medicinal aerosol has no 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
