Description

Dry powder drug inhalation aid

The present invention relates to a dry powder medicine inhalation aid, in particular to a medicine inhalation aid having a vibrating screen which can further pulverize and refine the powder.

For powdered medicinal inhalers, refer to the Republic of China invention patent No. 325409 "Drug powder and powdered medicinal inhaler with integrated metering device". The powder mash of this case has an integrated metering device, which contains at least one measuring pocket. In order to receive a predetermined amount of powder, the integrated metering device can be removed from the position of the filling in a nearly lateral direction in relation to the direction of flow of the powder into the position of emptying.

Since the powder is very fine and is easily agglomerated by moisture, when the user inhales, the partially agglomerated and bulky powder may stick inside the inhaler or stay in the inside of the inhaler due to insufficient suction, causing the user not to absorb it. Enough medicine.

Thus, in order to provide a sufficient dose of micropowder, the present invention provides a dry powder drug inhalation aid comprising:

An inhaler having a suction port, a gas flow hole and a powder inlet, forming an air flow path between the suction port and the air flow hole, the inhaler comprising a screen corresponding to the powder inlet; and an air flow sensing unit In the inhaler, in the airflow path, the airflow sensing unit is configured to sense an airflow signal; a control unit is electrically connected to the airflow sensing unit for receiving the airflow signal to output an activation signal; The power unit is connected to the screen and the control unit for receiving the start signal to start, and controlling the screen to generate vibration.

Further, the power unit includes a motor and an eccentric coupled to the motor, the eccentric being coupled to the screen.

Further, a canister is disposed on the inhaler and corresponds to the entrance of the powder, and the canister has an electrically controllable cover electrically connected to the control unit.

Further, the screen has a pore size of no more than 100 microns.

Through the above technical features, the following effects can be produced:

When the powder falls onto the screen, the powder is passed through the pores having a pore size of about 100 μm by the vibration of the screen, and then dropped into the inside of the inhaler, so that the powder becomes finer and more easily inhaled by the user. Make sure the user can absorb enough powder.

In combination with the above technical features, the main effects of the present dry powder drug inhalation aid will be clearly shown in the following examples.

Referring to the first figure and the second figure, the embodiment includes:

An inhaler (1) has a suction port (11), a gas flow hole (12) and a powder inlet (13), and an air flow path is formed between the suction port (11) and the air flow hole (12). [[Airflow path (14) please refer to the third figure], the inhaler (1) and a screen (15) corresponding to the powder inlet (13), the screen (15) has a pore diameter of not more than 100 microns; The airflow sensing unit (2) is disposed in the inhaler (1) and located on the airflow path (14); a control unit (3) electrically connected to the airflow sensing unit (2); a power unit ( 4), comprising a motor (41) and an eccentric (42) connected to the motor (41), the motor (41) is connected to the control unit (3), the eccentric (42) is connected to the screen (15); A medicine tank (5) is disposed on the inhaler (1) and corresponds to the powder inlet (13). The medicine tank (5) has an electrically controllable cover (51) electrically connected to the control unit (3).

Referring to the third figure, the user inhales from the suction port (11), and the airflow enters the inhaler (1) from the airflow hole (12), and the airflow sensing unit (2) senses the airflow. Entering to generate an air flow signal, the control unit (3) receives the air flow signal to control the cover (51) of the medicine can (5) to open, so that the quantitative powder in the medicine can (5) is from the powder inlet (13) Falling into the screen (15), the control unit (3) will output a start signal to the motor (41), so that the motor (41) can receive the start signal to start, thereby controlling the screen ( 15) generating a vibration, the vibration of the screen (15) passes the powder through the pores having a pore size of about 100 μm, and then falls to the inside of the inhaler (1), and enters along the air flow path (14). In the mouth of the person, when the powder passes through the screen (15), it will become more detailed and thus more easily inhaled by the user, ensuring that the user can absorb a sufficient amount of the powder.

In view of the above description of the embodiments, the above-described embodiments are merely a preferred embodiment of the present invention, and the implementation of the present invention is not limited thereto. The scope, that is, the simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the creation of the creation, are within the scope of this creation.
