Description

Intelligent inhaler

Technical Field

The invention relates to medical equipment, in particular to an intelligent auxiliary inhaler for treating respiratory diseases such as asthma and the like.

Background

The aerosol inhaler is a common treatment device for respiratory tract patients (such as asthma patients), and is used together with bottled or canned aerosols or powder, such as Mo Tuolin and other medicines, to relieve bronchospasm of patients suffering from asthma or chronic obstructive pulmonary diseases (reversible airway obstruction diseases), and to acutely prevent exercise-induced asthma or bronchospasm induced by other allergens, thereby achieving emergency treatment.

The top of the bottled pneumatic medicine bottle is provided with a medicine powder outlet, and the medicine quantity pressed out each time can be ensured to be a fixed value. However, the correct use method should make the powder directly enter the trachea and bronchi under the condition of deep inhalation, and the powder staying in the oral cavity does not have enough curative effect on bronchospasm. Patients often feel uncomfortable on themselves and use larger amounts of powder even more often, and the powder is swallowed by the esophagus or stays in the mouth, which is also bad for the body.

Generally, the instructions of Mo Tuolin and other medicines explain the use method, but the patient cannot always operate correctly during the use process, especially when using by novice, so as to influence the curative effect of the medicine powder.

In view of this situation, some large medical equipment manufacturers abroad, such as microtechnology corporation of new jersey axle in united states, claim patent CN200410085926.1 "air intake device for delivering powdered medicine from a container", which is an air intake device for delivering powdered medicine from a container, the air intake device comprising: an audio controller, said audio controller including an audio microphone element for detecting the sound of the air flow in the vicinity of said audio microphone element and generating a signal representative of said air flow; and a high frequency vibrator for vibrating the container in response to the signal, the vibrator thereby being operable to induce the medicament into the airflow.

The product has considered that only after the inhalation volume reaches a proper value, the trachea and the bronchi are fully opened, and the inhalation of the medicinal powder is only at a proper time, but the inhalation of the medicinal powder is not strictly matched with the proper inhalation air flow and the effective inhalation duration of the medicinal powder, so that the user can cause insufficient total inhalation air flow to cause the medicinal powder to fully enter the focus, and the defects still exist.

Detailed Description

An intelligent inhaler is used in combination with a push-type medicine can for treating respiratory diseases, and can monitor the use condition of medicines by a user and remind the user of correctly using the medicines.

As shown in fig. 1, the manual intelligent inhaler is composed of a canister mounting seat, an air flow mixing channel and a monitoring part, the canister 2 is reversely inserted into the canister mounting seat 1, and the medicine outlet 21 of the canister is ensured to extend into the air flow mixing channel.

The air flow mixing channel is started from an air inlet hole 5, is stopped and is connected with a suction nozzle 3, is a tubular channel and is divided into two parts by a filter screen 8, a gong 6 and a microphone 7 are arranged at the part close to the air inlet hole, and a medicine mixing area is arranged at one side close to the suction nozzle. The filter screen can ensure that the medicine powder cannot be used as a gong part, and avoid the sound distortion of the gong or the pickup failure of a microphone.

A display screen 10 and a sounding element 13 are arranged on one surface of the medicine tank mounting seat facing to a user, and the sounding element is a small loudspeaker, a loudspeaker or a buzzer. A circuit board 4 is arranged between the air flow mixing channel and the medicine tank mounting seat, a battery and a processor are arranged on the circuit board, and a signal transmitter 12 is arranged on the outer side of the air flow mixing channel.

When the user inhales through the suction nozzle, the air flow of the air inlet hole is larger than a certain preset value, the air pipe and the lung of the user are fully opened, meanwhile, the gong emits sound with special frequency, the microphone receives the sound and then transmits the sound to the processor of the circuit board, the processor is responsible for recording the time t1 when the sound starts to emit, and continuously counting until the air suction of the user is saturated, the air suction quantity is insufficient to trigger the gong to emit sound, the sound disappears, and the processor records the time t2 when the sound stops again.

The time difference between t2 and t1 represents the duration of time that the user's airflow reaches a certain measure C, and in general, the user's inspiratory airflow exceeds the measure C, i.e., ensures that the inhaled drug powder reaches the focal region of the trachea and lungs.

As shown in fig. 1, a reset spring 11 and a contact switch 9 are arranged at the bottom of the medicine tank seat, when the medicine tank is pressed down by a user, the contact switch is propped against the top of the medicine tank (the medicine tank is inverted at the moment), medicine in the medicine tank starts to be sprayed out, at the moment, the contact switch transmits a signal to a processor of a circuit board, the processor is responsible for recording the touch starting moment ta of the contact switch, when the user releases the medicine tank, the reset spring drives the medicine tank to move upwards, the medicine in the medicine tank stops to be sprayed out, at the moment, the contact switch loses contact, and the processor records the moment tb again. The time difference between the time tb and the time ta is the continuous ejection time of the medicine.

In general, a medicine for treating respiratory tract is sprayed in two modes, one is a pressing type structure, one is pressed once, a fixed medicine amount is sprayed, and the other is an internal pressure type, and the sprayed medicine amount is proportional to the duration of pressing. For the former medicine pot, only the time for inhaling the medicine is controlled, so that the medicine can be ensured to directly reach the focus. For the latter canister, it is necessary to meter the duration of the drug ejection. And the duration of the drug ejection should be effective in the case where the user's trachea and lungs are sufficiently open. The intelligent inhaler can simultaneously meet the requirements of the medicine tanks in the two spraying modes.

For the manual intelligent inhaler, the correct operation is that the user presses the medicine tank after hearing the sound generated during inhalation, the medicine powder is sprayed out, mixed by the airflow mixing channel and inhaled into the respiratory tract from the suction nozzle, and a certain airflow (the gong continuously sounds) is continuously kept in the process of inhaling the medicine powder.

Fig. 3 to 6 are graphs of time and amount of medicine inhaled and sprayed by a user, wherein the horizontal axis represents time and the vertical axis represents inhalation amount. Where D is the peak inhalation volume and C is a standard inhalation volume sufficient to bring the powder into the respiratory tract. Metric C is also the lowest air flow for which the gong just sounds.

In general, the inhalation process of the user starts from 0 and gradually increases, and reaches the inhalation amount reaching the measurement C at a certain moment ta, the inhalation amount gradually increases until approaching a peak value D, then is kept relatively flat and gentle for a period of time, and after the lungs are fully opened, no more air can be inhaled, and the inhalation amount rapidly decreases.

Because the time when the user presses the canister and the time when the gong is heard often cannot be the same, as shown in fig. 3, the user presses the canister first and then begins inhaling. I.e. the spray switch of the medicine tank is pressed at the time ta, the medicine powder can not be effectively inhaled into the respiratory tract until the time t1, the medicine tank is released at the time tb by the user, and the effective inhalation time is continued to t2.

From the above analysis, it can be seen that although the powder is ejected during the period ta to t1, the inhalation amount is obviously insufficient, and a small amount of inhalation will send the powder into the oral cavity only, and not further to the focus of the respiratory tract, so that the ejected powder in the period ta to t1 is ineffective and wasteful. In the period from t1 to tb, the sprayed medicinal powder can penetrate into the respiratory tract and is an effective medicinal dose. While after tb to the stage t2, the powder has not been ejected, although the user is still striving to inhale, and inhalation at this time is also ineffective. This results in an excessive amount of powder and is not well absorbed by the respiratory tract.

Fig. 4 shows another common situation of the user, the user inhales first, and presses the canister after hearing the sound made by the gong, i.e. t1 is earlier than ta, and the user continues to press the canister after the inhalation amount is insufficient, and continues to spray until tb is over. The two disadvantages occur at this moment, namely, if the time between t2 and ta is too short, a large amount of sprayed medicine powder is insufficient to be inhaled into the respiratory tract by the patient, the medicine dosage is insufficient, and the other is that the large amount of sprayed medicine powder is only inhaled into the oral cavity due to insufficient air flow of inhalation, so that waste is caused, the patient can mistakenly take enough dosage for the respiratory tract, and even the disease control is delayed.

Fig. 5 is a timing chart of a more accurate method of using the manual smart inhaler, in which a user inhales deeply, and after hearing the sound of the gong, the user presses the canister rapidly, and the powder is ejected, the powder ejection time is enough, and after hearing the prompt tone or display screen of the smart inhaler, the canister is released, and after stopping the ejection, the inhalation amount is gradually reduced.

At this time, the effective ejection time of the medicine is tb-ta, and the time is in a section with enough inhalation amount, and the medicine can directly reach the focus of the respiratory tract.

The invention also comprises an automatic intelligent inhaler, as shown in d in fig. 2 and 3, which is different from manual operation in that a set of medicine tank mounting seat is additionally arranged on the medicine tank mounting seat, a trigger mechanism is arranged in the medicine tank mounting seat, a control end of the trigger mechanism is connected with a processor circuit on a circuit board, a trigger end of the trigger mechanism is fixedly connected with the medicine tank, and a trigger stroke of the trigger mechanism is larger than a minimum distance for triggering spray of a nozzle of the medicine tank.

Therefore, the user does not need to press the medicine tank manually, only needs to inhale the air flow and surpass the measurement C, makes the gong make suitable sound, triggers the microphone, and the processor just starts trigger mechanism voluntarily, pulls down the medicine tank, spouts the medicine to it calculates the blowout time voluntarily, reaches and sends sound or/and demonstration suggestion to the user after predetermineeing the time, and the patient can stop inhaling, so as to ensure that the powder measurement is sufficient. If the patient does not reach the desired inhalation time, the smart inhaler will also give false alarms and prompts to continue inhalation.

The above-mentioned one is to spray the pressure-operated structure medicine pot of the fixed dosage, the corresponding time of spraying is comparatively fixed, can regard as a definite value to consult, namely only need consider between t1 and t2 time difference can cover the spraying time of the medicine pot can, its timing diagram is the same with figure 6.

In summary, in the present invention, determining whether the ejection of the medicine is up to the standard can be performed according to the following method, wherein Δt is the minimum ejection duration of the medicine tank to ensure a sufficient amount of the medicine.

When the intelligent inhaler is operated manually, a user uses a judging method of whether the intelligent inhaler is correct or not, and the method comprises the following steps of:

step 1: the starting moments t1 and t2 of the pronunciation are acquired and recorded, and the time ta when the contact switch is triggered and the time tb when the contact switch is released are acquired and recorded.

Step 2: the larger values of t1 and ta are compared, the smaller values of t2 and tb are compared, and the time Δt for which the difference between them persists is calculated.

Step 3: the processor judges whether the delta T is larger than a preset value delta T or not, and displays the result through a display screen or prompts through a loudspeaker. If Δt is greater than or equal to a preset value Δt, the test is considered to be acceptable, and if Δt is less than the preset value Δt, the test is considered to be unacceptable.

When the intelligent inhaler is automatically operated, when the inhalation amount reaches a preset value C, the gong sounds, and when the starting time t1 of sound is automatically recorded, the device automatically sprays the medicine. When the inhalation amount of the user reaches saturation and is lower than the preset value C, the ending time t2 is automatically recorded. The processor judges whether the time difference between T2 and T1 is larger than a preset value delta T, and displays the result through a display screen or prompts through a loudspeaker. And if the time difference between T2 and T1 is greater than or equal to a preset value delta T, the test result is qualified, and if T is smaller than the preset value delta T, the test result is unqualified.

As intelligent inhaler, a trigger mechanism 14 is arranged in the medicine tank mounting seat, the control end of the trigger mechanism is connected with a processor circuit on the circuit board, the trigger end of the trigger mechanism is in tight fit connection with the medicine tank, when the inhalation amount reaches a preset value C, the trigger mechanism is automatically started to pull the tank body of the medicine tank downwards, and the spray head of the medicine tank is triggered to spray medicine. The trigger travel of the trigger mechanism is larger than the minimum distance for triggering the spray of the spray nozzle of the medicine tank.

The intelligent inhaler comprises a manual intelligent inhaler and an automatic intelligent inhaler, can judge whether the user correctly and incorrectly inhales the medicine powder or not, and records the judgment, so that automatic timing reminding is realized, even through networking, the directional help of doctors is obtained, the respiratory patient can be helped to treat the diseases more effectively, and the pain is relieved. And it can change the medicine jar, repeatedly use, practice thrift use cost.
