Abstract

This invention relates to an inhalation driving medicine inhaler used for solving the deficiency of poor efficacy due to medicament being unable to reach depth of throat when being sprayed, resulting from inconsistent time of inhaling and medicament bottle pressing when a user uses a medicine inhaler. This invention comprises an inhalation sensing unit and a pressing unit disposed on an inhaler body and a control unit electrically connected to the inhalation sensing unit and the pressing unit. When the user is inhaling, the inhalation sensing unit senses and generates an inhalation signal and the control unit receives the inhalation signal and controls the pressing unit to press the medicament bottle to spray the medicament, so as to achieve the effect of consistent inhalation and medicament spraying, thereby enabling the medicament to elaborate the optimal therapeutic effect.

Description

Inspiratory drive drug inhaler

The invention relates to an inhalation-driven drug inhaler, in particular to inducing a user to inhale, and after a delay time, controlling the pressing unit to press the medicine bottle to eject the medicine, so that the medicine can reach the deep throat of the user accurately. A drug inhaler that works best for its effectiveness.

Patients currently in need of treatment with inhaled medicaments are usually administered by means of a single dose inhaler. When the user inhales, the medicine bottle is simultaneously pressed, so that the medicine bottle sprays the medicine for the user to inhale.

The structure of the medicament inhaler is, for example, the "Inhalation device and its recordable medication information device" of the Republic of China Patent No. I310905, which can be used to record the effective medication time and the number of effective medications for a patient using an inhalation device. Or the Republic of China Patent No. I224513 "Dose counter for medicinal inhalers", including an accurate and consistent drug dosing system for dispensing a discrete amount or dose of dry powdered drug for inhalation; a decompression system, The pressure in the drug storage chamber that manages the inhaler to ensure consistency of the dispensed dose; and a dose counting system for displaying the amount of dose dispensed from the inhaler.

However, when the user inhaler is used by the user, the inhalation of the mouth of the human body is often inconsistent with the time of pressing the bottle by the hand. When the medicament is injected, most of the medicament stays in the mouth and cannot be directly sprayed into the throat. This results in a lack of efficacy.

Therefore, in order to solve the problem of inhalation of the mouth of the human body and the pressure of the hand pressing the bottle when using the inhaler, the lack of efficacy is caused. In this case, an inhalation-driven drug inhaler is proposed, which includes:

An inhaler body, the inhaler body includes a suction member having a space at both ends, and a drug fixing seat is coupled to the inhalation member, and a medicine bottle is disposed on the medicine fixing seat; The sputum control unit is electrically connected to the snorkeling unit; the squeezing unit is disposed on the medicament holder of the inhaler body, and the pressing unit is electrically connected to the control unit. And the pressing unit is aligned with the aforementioned vial.

An inhalation signal is generated by inhaling from the inhalation member and being sensed by the inhalation sensing unit. The control unit receives the inhalation signal and controls the pressing unit to press the vial to eject the medicament.

Further, the control unit includes a timing module. After receiving the inhalation signal, the control unit calculates a delay time by the timing module. After the delay time, the control unit controls the pressing unit to press the medicine bottle. And spray the medicine.

Further, the air induction unit includes a channel connecting the inside of the suction member, and a piston extends into the channel, and a return spring is connected between the piston and the inner wall of the channel, and the air induction unit further includes The two conductive terminals are disposed on the suction member, the two conductive terminals are electrically connected to the control unit, and a hook is connected to the piston and corresponds to the conductive terminal. When the air is sucked from the suction member, the piston is displaced. The hook is hooked to the one of the conductive terminals to contact the other conductive terminal conducting circuit to generate the inhalation signal, and the return spring resets the piston after the end of inhalation.

Further, the pressing unit comprises a sleeve sleeved on the medicament fixing seat of the inhaler body, and a slide rail is disposed in the sleeve, a row of teeth is inserted into the slide rail, and the row of teeth is aligned The medicine bottle is further engaged with the gear by a gear, and the gear is sleeved on a rotating shaft of the motor, and the motor is electrically connected to the control unit.

Advantages of the invention include:

1. The inhalation sensing unit is used to sense the time when the user inhales the inhalation member to generate an inhalation signal, and then receives the inspiratory signal through the control unit, and controls the pressing unit to press the medicine bottle to eject the medicine, thereby achieving inhalation and The consistent effect of spraying allows the agent to exert the best therapeutic effect.

2. Using the timing module to calculate the delay time, at the end of the user's inhalation, about 0.5 seconds after the user starts inhaling, the control unit then controls the pressing unit to press the medicine bottle to spray the medicine, so that the medicine can reach the deep throat.

3. The invention has the advantages of simple structure, low cost and good practicability, and is highly competitive in the market.

In combination with the above technical features, the main effects of the inspiratory-driven drug inhaler of the present invention can be clearly demonstrated in the following examples.

Referring to the third and fourth figures, the user inhales from the inhalation member (11), at this time, since the passage (31) of the inhalation sensing unit (3) communicates with the inside of the inhalation member (11), The piston (32) is displaced by the vacuum suction force, and simultaneously compresses the return spring (33), and the piston (32) drives the hook (35) to catch the one of the conductive terminals (34) to contact the other one due to the displacement. a conductive terminal (34) and a conducting circuit further generates an air inhalation signal, and the inhalation signal is received by the control unit (4) [this part of the electronic circuit is a commonly known inductive electronic circuit, so the specification and the illustration are not detailed Said induction electronic circuit].

After the control unit (4) receives the inspiratory signal, the timing module (41) calculates a delay time, which is about 0.5 seconds after the user starts inhaling to the end of the user's inhalation. After the delay time, the control unit (4) controls the motor (55) of the pressing unit (5) to act, the motor (55) drives the gear (54) to rotate, and the gear (54) drives the row The tooth (53) advances in the slide rail (52) to press the medicine bottle (2) to spray the medicine bottle (2); however, the method is not limited to the above-mentioned pressing mechanism, and the piston displacement in the cylinder may be used. Or a variety of other pressing mechanisms are used as the mechanism for pressing the vial (2). Through the above method, the effect of inhaling and spraying can be achieved, and the medicament can reach the deep part of the throat without leaving too much medicament in the oral cavity, so that the medicament can exert the best therapeutic effect.

Referring to the second figure, when the user inhales the air, the two conductive terminals (34) are contacted, and the conduction circuit generates the air suction signal, the return spring (33) of the air induction unit (3) will The spring force is released to reset the piston (32), waiting for the next use to produce the effect described above.
