Spray counter

The present invention relates to a spray counter that clearly shows the number of administrations, and more particularly to a breathable spray can or a similar structure for use in asthma patients.

Life is alive, life, old age, illness, and death are inevitable. People who are ill need to seek medical treatment as soon as possible to avoid more serious illnesses. In addition to sudden accidents or cardiovascular diseases with large climate change, emergency medical treatment should be urgently provided. Diseases have more time to seek treatment.

Taking asthma as an example, a patient with asthma will receive a can of asthma-fighting spray cans for asthma medication. When the patient returns home, if there is asthma in the daily routine, the asthma can be used to spray the cans and nozzles. The starter is placed in front of the mouth and the spray can is pressed, so that the asthma in the can is inhaled into the lungs of the patient, so as to expand the trachea to prevent the patient from breathing out or inhibiting the inflammation of the trachea, thereby achieving self-treatment. However, the traditional asthma dose spray can not know the amount of the remaining drug. If the patient has prepared a bottle of asthma spray can, it can solve the urgent need. If the patient does not prepare the extra asthma spray can, there is no other side. When people are sick, if they are suffering from asthma, the patient may not be able to save themselves by using a pant spray can with no medication in their possession. It is more likely to cause a death accident due to the missed prime time of emergency treatment.

And the conventional anti-asthmatic quantitative spray can uses CFC (Clorofluorocarbon) as the propellant. Since the CFC gas itself has low water absorption capacity, it is generally recommended to throw the spray can into the water and observe the drug in the tank in the tank. In the case of the remaining amount, in addition to being quite inaccurate, such a measurement method is also inconvenient for using the water ups and downs method to test the stock. In addition, because CFC gas is a substance that will destroy the ozone layer, it is essential for medical use, and will be completely replaced by the new HFA (Hydrofluoroalkane) propellant gas-based anti-asthmatic spray can product.

The HFA gas is used in the quantitative spray cans for asthma. Although the propellant gas of the HFA itself has a strong ability to absorb moisture, it is generally not recommended to drop the anti-asthmatic spray cans with HFA as a propellant into the water for the stability of the drug. The remaining drug stock, for the safety of the patient's drug use, must be designed to show the function of the count, in order to facilitate the patient to understand the remaining state of the drug.

The general solution is to design a mechanical window counter on the plastic nozzle starter with a quantitative spray can for asthma. However, this will increase the manufacturing cost of the plastic nozzle starter that is attached to the product by several tens of times. And the environmental protection burden of plastic materials increased, and the window area font is too small, which is unfavorable for people with poor visual acuity to read and possible failures, resulting in incorrect interpretation of doses. Therefore, the inconvenience in use and the uncertainty of stock still exist.

The main object of the present invention is to provide a spray counter capable of clearly showing the advantages of the number of remaining medications, avoiding the trouble of insufficient amount of medicament sprayed in an emergency, and returning to zero after repeated use and re-application for new asthma dose. The spray can is used to achieve the environmental protection purpose of reducing the material demand of the plastic nozzle starter, and the large display subtitle is beneficial for the user to read the residual drug amount.

In order to achieve the above object, the spray counter of the present invention is combined with a spray can for asthma, and is composed of an upper cover having a window on the surface, a circuit board, a positioning ring, a battery and a bottom cover, wherein the circuit board has a a counting circuit and a display screen, the display screen is disposed under the window, and the circuit board is positioned through the positioning ring, and the bottom sleeve is connected to the upper cover by the bottom-up device; thereby, the spray is transmitted through the bottom cover The counter is placed at the rear end of the asthma spray can.
