Abstract

FIELD: medicine.

SUBSTANCE: thermoelectric device for performing electrophoretic medical procedures contains an electrically conductive plate electrically connected to a constant current source, brought into contact with a body region through a porous substance impregnated with a drug. Thermoelectric modules (TEMs), electrically connected to a constant current source through a control unit, are brought into thermal contact with the plate. These TEMs contain working and supporting junctions. And the working junctions of TEMs are conjugate, with the provision of thermal contact with minimal thermal resistance, with the upper plane of the conductive plate. Said supporting junctions are in contact, with the provision of thermal contact, with the base, which plays the role of heat rejection of excess heat into the environment and is made of highly heat-conducting material. Further, the capacity for drugs through an elastic tube is connected to a porous substance, which is attached to the lower plane of the conductive plate and in which a temperature sensor is installed, electrically connected to the control unit. Said TEMs are divided into sections with the possibility of their serial connection in accordance with the signal that comes from the temperature sensor located in the porous substance.

EFFECT: invention provides the ability to control the temperature of the electrophoretic agent directly during the procedure.

Description

The invention relates to medicine, in particular, to devices for conducting electrophoretic procedures.

Scope: in medical equipment, namely in physiotherapy and reflexology for the introduction of drugs of the human body through electrophoresis at a controlled temperature of the administered drug.

Irritation of nerve receptors by direct current during the procedure, and subsequently prolonged continuous irritation of them with ions of a medicinal substance introduced into the patient’s skin, is transmitted to higher autonomic centers. The resulting response in the form of a generalized ion reflex is specific for the action of the administered drug substance. This substance enters into metabolic processes and affects cells and tissues in the affected area. Slowly entering the blood and lymph, the medicinal substance introduced by the method of electrophoresis, acts on organs and tissues sensitive to it, on the body as a whole.

Thus, drug electrophoresis has the following advantages over other methods of introducing a drug into the body: a drug is administered in the form of individual ingredients, while its pharmacological activity is increased, and ballast substances do not enter the body; the drug substance is injected directly into the tissue of the pathological focus, creating a sufficiently high concentration in it, without saturating the entire body; Unlike oral and parenteral methods of administering drugs to the body, electrophoresis is less likely to cause negative reactions to the administered drug and its side effects are less pronounced, as well as the drug is administered without compromising the integrity of the skin, therefore, sterilization of the drug is not required.

Known devices that provide electrophoretic procedures [1, 2].

However, the disadvantage of these devices is the lack of temperature control of the drug during the procedure, which can cause unpleasant, and sometimes painful sensations in the patient.

The aim of the invention is the provision of temperature control of the drug directly in the process of electrophoretic procedures.

This goal is achieved through the use of thermoelectric semiconductor converters operating in cooling or heating mode, depending on the temperature of the medicine set by the medical personnel on the control unit.

The technical result is the ability to control the temperature of the electrophoretic agent directly during the procedure.

The technical result is achieved through the use of TEM working in heating or cooling mode to control the temperature of the plate, through which the necessary current is supplied through the porous substance with the drug for therapeutic effect.

The block diagram of the proposed device is shown in FIG. one.

The device consists of thermoelectric modules (TEM) 1, electrically connected to a direct current source through a control unit (not shown in Fig.), The reference junctions of which are in contact, providing thermal contact, with base 2, which plays the role of heat discharge of excess heat into the environment, made of highly conductive material. Working junctions of TEM 1 are coupled, providing thermal contact with minimal thermal resistance, with the upper plane of the electrically conductive plate 3 (for example, from lead). A porous substance 4 is attached to the lower plane of the conductive plate 3, in which a temperature sensor 5 is mounted. A container for drugs 7 is connected to the porous substance 4 by means of an elastic tube 6. To ensure rigidity of the entire structure, the base 2 and the conductive plate 3 are connected by fixing devices 8. For convenience of positioning on a part of the human body, a holder 9 is attached to the base 2. which comes from the temperature sensor 5 located on the porous substance 4.

The device operates as follows.

The drug for electrophoresis is poured into a container 7, which through an elastic tube 6 enters the porous substance 4, falling into which is evenly distributed. A temperature sensor 7 located on the porous substance 4 monitors changes in the temperature of the drug. Using the holder 9, the device is brought into contact with a portion of the body where electrophoresis is performed.

The procedure begins by turning on the control unit (not shown in FIG.). The control unit sets the required temperature of the drug. When the temperature of the drug changes from the set value, the control unit turns on the TEM 1 through the power supply either in the cooling mode if the temperature of the drug is higher or in the heating mode if the temperature is lower. Switching from one mode to another is carried out by switching the polarity of the TEM 1 power supply. By changing the TEM 1 power supply current, as well as by connecting the TEM 1 sections in series, the temperature of the injected drug can be smoothly controlled by changing the temperature of the TEM 1 working junctions and electrically conductive plates 3. Temperature the drug will also change due to the fact that the porous substance 4 is in thermal contact with the conductive plate 3, and the heat exchange process will occur ak by conduction material, and due to microconvection in the drug, which is impregnated with a porous substance. The design of the plate 3 electrically conductive allows you to apply electric current to it to conduct directly electrophoretic process.
