Description

The utility model relates to the medical field of application, to devices for inhaling drugs. This class of devices is called inhalers, they are used in the treatment and prevention of respiratory diseases.

A known analogue is a portable universal inhaler, US patent No. 20070056581A1, 03/15/2007, containing the outer part and the inner part inserted into the outer part. In the inside is a container with a drug. The inside contains a universal connector for the use of various commercially available drug containers. The inner and outer parts connected together form a chamber of sufficient volume in order to accommodate a measured dose of medication. The mouthpiece is connected to the chamber with the possibility of inhaling medication from the chamber through it.

The disadvantage of the analogue of the device is the possibility of its simultaneous use with only one type of aerosol drug, lack of a built-in peak flow meter, dose counter, lack of an electronic module that provides functions for processing and storing data on the active substance, dosage, frequency of reception, peak flow metering data, diagnosis, visits to the doctor , inspection data, inspection results.

A powder inhaler is also known - RF patent No. 2491103, 08/27/2013, selected as a prototype of the proposed inhaler, comprising a housing and a mouthpiece, said housing including an inlet and outlet, and the mouthpiece is detachable from said housing, a cartridge adapted to said a dry powder inhaler and containing dry powder medicine for inhalation, and the dry powder inhaler contains air channels configured to have a predetermined distribution of air flow and around and through said cartridge, configured to mix the drug with air, forming a stream of powder for delivery to the patient’s respiratory system.

The first drawback of the analogue is that this device can only be used to take one drug, which makes it difficult to control the correctness and regularity of taking several drugs. The second disadvantage of the analogue is the lack of a means of monitoring the correctness and regularity of the drug. These two shortcomings define the technical problem described below, which is proposed to be solved by the proposed utility model.

Historically, all companies that produce inhaled drugs, original or generic, develop their own delivery vehicles for them - inhalers. Moreover, each of them is unique and has a number of technical features and rules of practical application, which are mandatory for effective therapy. That is, for taking various drugs, the patient is forced to use several types of inhalers developed by various manufacturing companies. These inhalers have various designs and features of use. In this case, the patient is forced to know and follow the instructions for use of each inhaler, which are different. Under such conditions, the patient in most cases is not able to perform the inhalation procedure correctly, which leads to a decrease in the effectiveness of therapy. In clinical studies, it was shown that when using more than one drug in the regimen of taking more than once a day, patients have difficulty remembering information about the active substance, dosage, frequency of administration and other aspects of therapy. A multiple decrease in adherence to therapy was noted with its increase at each next step: plus one drug or plus one dose per day. Monitoring the correct use of drugs in the treatment of bronchopulmonary diseases, such as asthma, is impossible without regular monitoring of the function of external respiration, for which a peak flow meter is used.

The technical result of the proposed utility model is to ensure control of the correctness and regularity of the simultaneous administration of several drugs during the course of therapy.

The solution to the technical problem in an inhaler containing a housing with inlet and outlet openings, a mouthpiece, a cartridge containing a dry powdered drug substance for inhalation, air channels made with the possibility of mixing the powder medicine with air, forming a stream of powder for delivery into the respiratory tract of the patient through the mouthpiece, is achieved by the fact that the inhaler has three cartridges, a peak flow meter and an electronic module connected to the body of the inhaler, and containing a printed circuit board with a control controller, lementom power, memory module, transceiver Bluetooth, electronic module sync button, with peak flow meter and cartridges have sensors connected to an electronic module.

Figure 2 shows the inhaler with the cartridge removed.

Figure 3 shows an electronic module without a housing.

Figure 4 shows a nebulizer with a cartridge in section.

Figure 5 shows the shape of the keys for installing cartridges in the right place in the body of the inhaler.

The inhaler comprises a housing 1 with an inlet 2 and an outlet 3 openings, a mouthpiece 4, cartridges 5 containing a dry powder medication for inhalation. Air ducts 6 connected to the chamber 7, into which the drug enters from the cartridge 5, and through which the air stream is passed, and mixing the powder drug with air, forming a stream of powder for delivery to the patient's airways through the mouthpiece 4. The inhaler has three cartridge 5, peak flow meter 8 and electronic module 9. The electronic module 9 is connected to the housing 1, and contains a printed circuit board 10, a control controller 11, a battery 12, a memory module 13, a Bluetooth transceiver 14, button 15 synchronization of the electronic module 9. The peak flow meter 8 has a sensor (not shown), connected to the electronic module 9.

Consider an example of a specific inhaler implementation. The main parts of the inhaler, such as the housing 1, the cartridge housing 5, the housing of the electronic module 9, the peak flow meter parts 8, button 15 are made of polypropylene by injection molding on a thermoplastic machine. The mouthpiece 4 is made in one piece with the housing 1 and is part of it. The electronic module 9 is installed on the housing 1 of the inhaler using latches (not shown in the drawing), which allow you to remove the electronic module 9. Cartridges 5 are filled with medicinal powders in the factory. Cartridges 5 are attached to the body 1 of the inhaler using latches (not shown in the drawing) and have mechanical keys 16 for matching with the body, which have the shapes shown in Figure 5. The keys prevent the cartridges from being misplaced or two cartridges 5 of the same class of drugs into one inhaler. The peak flowmeter sensor 8 is an inductive sensor that converts the movement of the active element caused by the patient’s breathing into voltage, and then the voltage in the electronic module 9 is converted into an electronic signal, which is data on the respiratory capacity of a particular patient.

On the cartridge 5 there is a technological hole 17 for the flow of drug through it into the chamber 7 of the inhaler. The cartridges 5 are equipped with sensors (not shown) for monitoring the administration of drugs, as well as a mechanical dose counter 18 and a mechanical button 19 for activating the cartridge on each cartridge. On the body 1 of the inhaler there is a mechanical button 20 for switching between the peak flow metering mode and the drug inhalation mode.

Consider an inhaler in operation. The patient may be prescribed treatment, which consists in taking three drugs. If less than three drugs are prescribed, instead of cartridges with a drug, the inhaler is equipped with imitating cartridges that preserve the shape of the device, but do not contain any medicinal substance, or any mechanical or electronic device inside. Information about the diagnosis and the prescribed course of taking the medicine, including a single dose of taking the medicine, the number and frequency of doses, is downloaded to the electronic module 8 via the Bluetooth 14 transceiver. The patient installs 5 cartridges with the prescribed drugs in the inhaler. After installing the cartridge 5, part of the medicine from it enters the chamber 7. Using the activation button 21, it turns on the electronic module 9 of the inhaler, a light signal integrated in the activation button 21, indicates the device is ready.

The patient brings the inhaler to his mouth, grasps the mouthpiece 4 with his lips and takes a breath, as a result of which air is sucked in through the inlet 2, passing through the air channels 6 containing the chamber 7, and ending with the outlet 3 located in the mouthpiece 4. When passing the stream air through the chamber 7, it captures the powdered drug located in the chamber 7, and delivers to the patient's respiratory tract. The sensor located in the cartridge 5, records the dose of the consumed drug, information about which is transmitted to the electronic module 9, where it is registered. Information from the electronic module 9 through the Bluetooth transmitter 14 is transmitted to a computer or smartphone. When the next time for taking the drug comes, the application of the computer or smartphone gives a reminder to the patient. This allows you to follow the treatment regimen.

If you need to change the therapy (increase / decrease the dosage of already prescribed drugs or change the drugs), the doctor prescribes only the replacement of the corresponding cartridges 5, without changing the inhaler itself. Therefore, the patient is trained in the correct inhalation technique on the same device, excluding the variability factor of devices and techniques. Case 1 of the inhaler is replaceable, the period of its intensive use is 28 days. After that, the electronic module 9 is removed from it and rearranged on a new case.

The achievement of the technical result in the proposed device is due to

- the presence of three cartridges with various drugs in one device,

- the presence of a peak flow meter that allows you to control the correct intake of medications in the treatment of bronchopulmonary diseases, such as asthma, by controlling the function of external respiration,

- the presence of an electronic module that provides the functions of processing, storage and synchronization of data on the intake of several drugs with the software of a computer or smartphone. This allows you to monitor the intake of drugs. Subject to the legal aspects, the patient can provide access to the personal doctor’s personal health data, however, the manufacturer is not responsible for the correctness of these procedures.

The proposed technical solution increases the efficiency of use of the inhaler and, as a result, increases the effectiveness of the therapy carried out with the help of it, saves time and money spent by doctors and patients on the study and retraining of the use of various types of inhalers and on drugs that are taken less effectively in the absence of a control system available in the proposed technical solution for multi-cartridge multi-dose inhaler.
