Description

BACKGROUND

Technical Field

The present disclosure is related to an atomizer and an atomization method for generating a plurality of pharmaceutical aerosols, and in particularly, to an atomizer and an atomization method for adaptively generating a plurality of pharmaceutical aerosols with different particle sizes according to a body state of the patient, treatment medicine for the patient and other factors.

Related Art

Pharmaceutical aerosols is an atomized liquid with medicine drug particles, and the pharmaceutical aerosols can enter the upper respiratory tract, lower respiratory tract and lungs of the human body, and be absorbed by the upper respiratory tract, lower respiratory tract and lungs to further treat specific diseases by using the medicine drug particles. The particle sizes of pharmaceutical aerosols that can be absorbed by different parts of the upper respiratory tract, lower respiratory tract and lungs are not the same. Usually, the particle size of pharmaceutical aerosols is expressed by the mass medium aerodynamic diameter (MMAD).

For example, the MMAD of the pharmaceutical aerosols which can be absorbed by the upper respiratory tract (such as, nose, throat, trachea) is about 5 μm to 50 μm, even larger than 50 μm; the MMAD of the pharmaceutical aerosols which can be absorbed by the lower respiratory tract is about 2 μm to 5 μm; the MMAD of the pharmaceutical aerosols which can be absorbed by the alveolar area is about 1 μm to 3 μm; and the MMAD of the pharmaceutical aerosols which can be absorbed by the parenchyma of lungs is less than 0.1 μm.

For patients with different symptoms, it is necessary to send drug particles to different tissues of the patient. However, at present, the atomizer can only produce pharmaceutical aerosols of a specific particle size, so it is necessary to use a plurality of atomizers that produce pharmaceutical aerosols of different particle sizes to meet various therapeutic needs. On the other hand, there are still differences in physique between patients. Therefore, pharmaceutical aerosols for the same tissue may still have differences in particle size to meet the purpose of precision treatment, or, because of different medicine drugs, the particle size of the pharmaceutical aerosols must vary to make the pharmaceutical aerosols be absorbed by the patient.

For example, for the treatment of throat inflammation, the pharmaceutical aerosols of the 40 μm particle size can be effectively absorbed by a throat of a first patient, however, the pharmaceutical aerosols of the 40 μm particle size cannot be effectively absorbed by a throat of a second patient, but the pharmaceutical aerosols of the 45 μm particle size can be effectively absorbed by the throat of the second patient. For example, for the treatment of infections in the alveolar region, the pharmaceutical aerosols of the 2 μm particle size which contains a first medicine drug can be effectively absorbed by the alveolar region of the first patient, the pharmaceutical aerosols of the 2 μm particle size which contains a second medicine drug cannot be effectively absorbed by the alveolar region of the first patient, but the pharmaceutical aerosols of the 3 μm particle size which contains the second medicine drug cannot be effectively absorbed by the alveolar region of the first patient. In short, there are needs of an atomizer and an atomization method for adaptively generating a plurality of pharmaceutical aerosols with different particle sizes according to a body state of the patient, treatment medicine for the patient and other factors.

The waveform pattern determination module 13 is configured to generate the modulation control signal according to the body state and the auxiliary information. That is, according to the factors which should be considered, the particle size(s) of the pharmaceutical aerosols or the particle size distribution the pharmaceutical aerosols can be determined. In short, the waveform pattern determination module 13 considers various types of data (even big data) to determine how to generate a vibration signal of a specific waveform pattern to the piezoelectric device 18, and the piezoelectric device 18 vibrates according to the vibration signal, thereby generating the corresponding particle size (for example, the particle size varies from 0.1 μm to 10 μm) or the corresponding particle size distribution of the pharmaceutical aerosols, thereby achieving the precision treatment for the patient. The modulation control signal can be one of a square wave, a triangular wave and a sine wave or the combination of the square wave, the triangular wave and the sine wave (i.e., the modulation control signal can be an arbitrary waveform). The modulation control signal is usually a low-frequency signal, such as a low-frequency signal of 0.05 Hz to 10 Hz, but the present disclosure is not limited thereto. In one of the embodiments, the data transmission interface DI can be removed, and the waveform pattern determination module 13 generates a modulation control signal only according to the body state.

The mixer is electrically connected to the high-frequency oscillation circuit 15 and the waveform pattern determination module 13, and the filter module is electrically connected to the mixer and is electrically connected to the piezoelectric device 18 through the power amplifier 17. The mixer is used to mix the modulation control signal and the high-frequency oscillation signal to generate a mixed signal.

There are many ways for the signal modulation module 14 to perform modulation. Although the above-mentioned modulation method is described with an example of intensity or amplitude modulation, the modulation manner can be one of intensity or amplitude modulation, phase modulation and frequency modulation or combinations thereof, and the present disclosure is not limited thereto.

The power amplifier 17 is used to amplify the vibration signal and output the amplified vibration signal to the piezoelectric device 18. In one embodiment, if the vibration signal is not affected by noise and the power of the vibration signal is sufficient to make the piezoelectric device 18 vibrate, the power amplifier 17 can be removed.

For example, the manipulation can be press once, long press for a few seconds, press quickly several times, and so on. The waveform pattern determination module 13 can generate the modulation control signal according to the switch control signal. In this way, the atomizer 10 can not only automatically change the particle size(s) of the pharmaceutical aerosols 20 according to the body state of the patient 30, but also manually change the particle size(s) of the pharmaceutical aerosols 20 by operating the manual switch P. Preferably, in the embodiment of the present disclosure, the priority of the switch control signal is greater than that of the body state, that is, when the atomizer 10 receives the switch control signal, it does not consider the body state of the patient 30, but uses the switch control signal to determine the particle size(s) of the pharmaceutical aerosols 20. However, it is noted that the present disclosure is not limited thereto.

The porous screen 19 is used to squeeze or press the liquid medicine 40 through the holes 191 of the porous screen 19 according to the vibration of the piezoelectric device 18 to generate a plurality of pharmaceutical aerosols 20, wherein the pharmaceutical aerosols has the particle size(s) corresponding to the modulation control signal. In addition, the nozzle 11 in FIG. 1 is located on the outer surface of the container CT, and is arranged corresponding to the plurality of holes 191 so as to eject or spray the plurality of pharmaceutical aerosols 20.

It is noted that, if it is assumed that the modulation control signal used is a square wave signal, the signal modulation module 14 is implemented by an electronic switch, the high-frequency oscillation signal is a 100 kHz sine wave signal, the square wave signal is a logic high level for 1.5 seconds and a logic low level for 1.5 seconds, the generated pharmaceutical aerosols will have the 3.5 μm MMAD. Further, under the similar condition, but the square wave signal is a logic high level for 1.5 seconds and a logic low level for 3 seconds, and then the generated pharmaceutical aerosols will have the 1.85 μm MMAD.
