Description

The utility model relates to the field of medicine and can be used for controlled injection of pure medical carbon dioxide [A61M5/00, A61M5/44, A61M5/52, A61M13/00, A61M16/00, A61M5/155, A61M5/165, A61M5/168, A61M13 /003].

Known from the prior art is a GAS DELIVERY DEVICE FOR THERAPEUTIC PURPOSES [US2008269669 (A1), published: 10/30/2008], in particular carbon dioxide, containing a gas supply reservoir connected via a supply line to a needle intended for insertion into the subcutaneous area of the patient, characterized in that it comprises a heating/sterilization system located in said delivery line in front of said injection needle to sterilize said gas and heat it to an optimal temperature so that it can be introduced under the skin of a patient, wherein the heating/sterilization system comprises a heater/sterilizer, containing a container containing a UV lamp that emits electromagnetic waves in the ultraviolet range between 250 nm and 280 nm.

The disadvantage of this analogue is the complexity of dosing carbon dioxide due to the lack of elements in the design that allow for controlled dosed administration of carbon dioxide in one injection, which threatens the safety of the patient’s body when increasing the single dose of carbon dioxide injection on the one hand and reduces the effectiveness of the procedure when reducing the single injection dose of carbon dioxide injection on the other side.

The closest in technical essence is a DEVICE FOR CARBOXYTARAPY [EP3673940 (A1), published: 07/01/2020], containing a high-pressure cylinder with carbon dioxide, a control device and controls for the specified device, an injection needle suitable for subcutaneous administration, a connecting line the internal volume of a cylinder with an injection needle, the line contains an outlet valve suitable for opening or closing the line, characterized in that said outlet valve is suitable for opening or closing said line with an activation frequency of more than 0.5 Hz and a flow rate of more than 100 cm ³ /min , wherein the device further comprises pressure regulating means for compensating the back pressure encountered by the flow of carbon dioxide at the outlet of the injection needle, heating means for heating the gas flow, and the line contains an intermediate reservoir suitable for storing carbon dioxide under pressure near said injection needles.

The pressure control means consists of means for measuring pressure and means for regulating the opening of valves.

The main technical problem of the prototype is the low reliability of the device, due to the implementation of pressure control means in the form of separate pressure sensors and means for regulating the opening of valves, which are also spaced in the diagram, which also affects the accuracy of pressure control and, accordingly, a single dose of carbon dioxide injection. Also, the reliability of the device is affected by the absence of carbon dioxide filtration elements in the line, which can lead to clogging of the line elements with mechanical impurities and failure of the device. The prototype does not indicate a method for regulating gas injection. It is only stated that activation of the device involves opening and closing the outlet valve with a frequency of more than 0.5 Hz and a flow of more than 100 cm ³ /min.

The purpose of a utility model is to eliminate the shortcomings of the analog and prototype.

The device for carrying out carboxytherapy contains a housing (not shown in the figures) inside which a controller 1 and a memory module 10 connected to it are mounted on a board, and a monitoring and control module 2 connected to the controller 1 is mounted on the outside of the housing. The monitoring and control module 2 is designed primarily in the form of a touch display.

The controller 1 and the monitoring and control module 2 are powered from the power supply 3, mounted inside the housing.

A receiver 4 for carbon dioxide, a heater 5, a valve 6, a filter 8 and a gas flow regulator 9 are mounted inside the housing.

Valve 6 can be made in the form of a 3-line, 2-position normally open distributor with electromagnetic control from controller 1.

Fittings are mounted on the body of the device (not shown in the figures) for connecting the device with a hose to a source of carbon dioxide and connecting a hose with an injection needle at the end to the device.

The source of carbon dioxide is made in the form of a cylinder with compressed carbon dioxide (not shown in the figures). The cylinder is equipped with a reducer (not shown in the figures).

To the source of carbon dioxide via the pneumatic inlet line through the first fitting mentioned above, a filter 8 and the first inlet of the valve 6 are connected in series, communicating in a normally open state through the heater 5 with the receiver 4. The injection needle along the output line communicates in series with the gas flow area regulator 9, the valve 6, heater 5 and receiver 4.

The heater 5 is predominantly designed as a flow-through type for heating the gas as it passes through the pipeline and is electrically connected to the controller 1 to control its on/off.

The regulator 9 is configured to change the diameter of the flow section of the line in the area between the valve 6 and the injection needle and, accordingly, the pressure and gas velocity at the outlet of the injection needle. The flow area regulator 9 allows the device to use valves 6 with different flow characteristics (throughput, nominal diameter), including from different manufacturers, since even valves 6 of the same type, but from different manufacturers, have different flow capacities within the limits of the characteristics declared by the manufacturer. This ensures high precision controlled dosing of a single injection of carbon dioxide. The mentioned regulator 9 together with valve 6 allows the carboxytherapy procedure to be carried out using the claimed device in a gentle, less painful mode, by providing adjustment of the gas supply pressure and, accordingly, the gas flow rate at the outlet of the injection needle, while simplifying the pneumatic part of the device as a whole and for Due to this, the labor intensity of device maintenance is reduced, which in turn affects the reliability of the device. Also, the combination of these advantages leads to a reduction in the time spent on the carboxytherapy procedure, which reduces the cost of paid services to the patient.

The filter 8 is designed to retain mechanical impurities and prevent them from contaminating the lines and pneumatic elements of the device. The regulator 9 can be made mechanical, electrical or electromagnetic.

Valve 6 is controlled by pressing pedal 7, which is connected to controller 1.

Controls for turning the device on/off are mounted on the body of the device for carboxytherapy. The fittings for connecting the carbon dioxide supply hose to the device from the source and the carbon dioxide supply hose to the injection needle are mounted mainly on the rear wall of the housing. There is also a pedal connector 7 mounted on the housing wall.

There are ventilation holes on the side wall of the case, mainly the rear one. In addition, the device can be equipped with a cooling fan (not shown in the figures), which is mounted inside the case for additional cooling of controller 1.

Controls for device modes are located on monitoring and control module 2.

Using the principle of carboxytherapy, the study device is a controlled injection of pure medical carbon dioxide into various areas of the body in accordance with the indications for use. Application (intradermal, subcutaneous, intramuscular) is carried out using needles of various lengths and thicknesses (25 - 32G).

Turn on the device. From the gas source, carbon dioxide is supplied through a constant-pressure reducer into the line inside the device, where the gas, through filter 8, normally open valve 6, heater 5, enters receiver 4. When passing through heater 5, the gas heats up. Heating of carbon dioxide is necessary because the carbon dioxide in the cylinder is liquefied and is at a temperature of 31°C, and when injected without preheating, the procedure will be sensitive and painful.

In controller 1, using the controls of the monitoring and control module 2, the volume of carbon dioxide required for the procedure is set, which can be adjusted from 0.1 to 50 ml and the volume of a single injection dose of carbon dioxide, which depends on the pressure at the outlet of the reducer, the duration opening of the valve 6 and the cross-section and, accordingly, the pressure at the outlet of the regulator 9. The specified operating mode, if necessary, is stored in the memory module 10 for subsequent quick selection.

Next, the injection needle is inserted and the valve 6 is opened by pressing the pedal 7, which supplies gas from the receiver 4 and the heater 5 to the regulator 9 and at the same time shuts off the gas supply from the gas source.

The gas, when passing from the heater 5 to the needle, is naturally cooled to a temperature of about 35-38°C depending on the ambient temperature and makes the procedure painless.

Valve 6 closes automatically depending on the set value of the single injection dose of carbon dioxide in controller 1. The duration of pressing pedal 6 does not matter. Pressing pedal 6 initiates a signal from controller 1 to open the valve, and then valve 6 closes based on a signal from controller 1, depending on the set value of a single injection dose of carbon dioxide, which, provided that constant pressure is supplied to the input of the device from the gas source, established by the conditional cross section of the regulator 9, depends only on the duration of opening of the valve 6.

During operation of the device during the procedure, the monitoring and control module 2 displays information about the volume of gas injected during the procedure, which is used to control the volume of carbon dioxide injections.

Injections can be superficial, intradermal, with a needle angle of 15 to 30 degrees, and deeper, subcutaneous with a needle angle of 45 degrees.

Examples of carboxytherapy procedures using the claimed device:

1. Treatment of the upper and lower eyelids.

The needle is inserted into an area located approximately 2 cm from the outer corner of the eye, the injection of carbon dioxide is made superficially, the angle of the needle is 15-30 degrees. The filling of the upper and lower eyelid area is quick. The patient, despite the visible swelling, does not feel pain. It is recommended to give 2-3 injections, approximately 2 cm apart in the direction of the lower eyelid. First, one and then the other periorbital areas are treated.

2. Treatment of the back of the hands

The injection is carried out superficially, the angle of the needle is 15-30°. Usually 4-5 injections are given in the middle of the back of the hand and in the wrist area.

3. Treatment of fat deposits on the abdomen.

Carbon dioxide is injected subcutaneously at an angle of 45 and/or 90°, depending on the severity of subcutaneous fatty tissue. Before the procedure, the abdominal area must be roughly divided into zones: two in the upper abdomen, four in the lower abdomen. Zones are treated in one procedure or with a break of a week. Usually 5-10 injections are administered in one area. If necessary, the procedure is repeated. The minimum number of procedures is 15-20.

4. Treatment of the head area.

The area for injection is the area of the trapezius muscles, the semispinalis cervicis muscle and the neck extensor muscles.

During the procedure, the patient should sit comfortably on a chair, holding the back of it with his hands, with only his head slightly tilted forward. CO ₂ is injected into the area of the trapezius muscles, neck extensors (in increments of 2-3 cm) and the suboccipital region until persistent hyperemia appears. When trigger points are detected, a deep needle insertion is used at an angle of 45°.

The cutting is carried out along two lines - the first line runs 1 cm below the hair growth on the back of the head, and the second line runs 1.5-2 cm under the first row. The distance between individual injections is approximately 1.5 cm. It is necessary to move in the direction from the ear (from the processus mastoideus) to the back and then in the opposite direction.

5. Back treatment.

Injection zones: acupuncture points corresponding to a particular problem.

The patient is placed face down on a couch with a special cutout. Trigger zones are palpated, focusing on the patient’s sensations. Needling is carried out according to the acupuncture scheme with a more thorough study of the triggers of the painful area - a slightly larger volume of injected gas can be applied to these points - we focus on 5 ml.

6. Treatment of keloid scars and hypertrophic scars.

Depending on the size of the scar, the procedure is performed in one or two stages. Carbon dioxide is injected in the direction of the force lines of the rumen. As a rule, when injecting the scar area, patients note a short-term burning sensation and crepitus, which disappears by the 2-5th minute of the procedure.

One-step procedure (papular route of administration). It is used intradermally directly into the scar. The distance between injections is 2 cm. The volume of injected gas is determined by the change in the red color of the scar and the appearance of a white shade of skin on it (blanching).

Two-stage procedure (linear retrograde injection method). First, the scar is punctured along the periphery, inserting a 30G needle (0.3×12.13 mm) “under it” in a linear retrograde manner. The number of injections depends on the length of the scar. Then an intradermal procedure is performed directly into the scar. The procedure is carried out until the scar is completely lightened.

After the carboxytherapy procedure, the patient is given a rest of about 30 minutes. On the day of the procedure and for 3-5 days after the procedure, the patient is advised to increase fluid intake.

To achieve the maximum therapeutic effect, the first 2-3 sessions every other day are optimal. For example, on Monday, Wednesday, Friday, and the following sessions 2 times a week. Optimal procedures: 1st week - 3 times (every other day), 2nd week - 2 times a week, 3rd week - 1 time, then procedures are carried out to maintain the final effect. A maintenance procedure once a month is suitable. Intensive courses of treatment can be repeated 1-2 times a year. The effect of carboxytherapy is usually visible after 3-6 sessions.

If you have problems with the musculoskeletal system, you can perform the procedure in two places at once - the back and shoulder, knee and elbows, shoulder blade and shoulder, etc.

Technical result - increasing the accuracy of controlled dosing of a single injection of carbon dioxide is achieved by connecting in the output line connecting the injection needle with the receiver 4 at the outlet to the injection needle a regulator 9 of the flow area, which ensures regulation of the pressure at the outlet of the injection needle and due to this at a constant pressure carbon dioxide from a source, a constant single dose of injection of carbon dioxide with one press of pedal 7, which is configured to open valve 6, and the closing of which is set in controller 1 and depends only on the duration of opening of valve 6. Filter 8 in this case eliminates clogging of the lines of the device and in first of all, regulator 9 and valve 6, which eliminates malfunctions in their operation and, accordingly, affects the accuracy of carbon dioxide dosing.
