SU992075A1 - Device for electrophoresis of medicinal preparations - Google Patents

Description

The invention relates to a medical technique, namely, devices for the introduction of medicinal substances into tissues, in particular for nasal electrophoresis.

A device for electrophore of medicinal substances is known through a mucous membrane of the nasal cavity containing wadded or gauze tampons (turban moistened with a medicinal solution introduced into each nostril. The ends of the pipe are placed on an oilcloth or rubber pad and pressed with a metal plate electrode. A device is also used in which metal electrodes are used as electrodes placed in on-trunks l

However, these devices for nasal electrophoresis create inconvenience for the patient, because during the whole procedure the patient is forced to breathe with his mouth open, which leads to

 you (the upper mucous membranes; the respiratory tract and adversely affect respiratory diseases.

The closest to the technical essence of the proposed method is the device for the electrophoresis of medicinal substances, including

: eyelets, a flexible element for fixing on the patient's head, a filler neck, cylindrical hollow electrodes and a source of current-2.

However, this device is inconvenient in operation, since the current passes not through the mucous membranes, but through the skin, which reduces the effectiveness of the procedure.

The purpose of the invention is to improve the convenience of carrying out the procedure of nasal electrophoresis of medicinal substances. To achieve this goal in an apparatus for electrophoresis of medicinal substances containing a container with eyelets, a flexible element for fixing the patient's head, a filler neck, cylindrical hollow electrodes and a current source in the walls The containers are made of a series of holes, and the electrodes are installed in these holes and are provided with a hygroscopic lining located on the outer surface of the electrodes.

Figure 1 shows the device, front view; figure 2 - the same, the view of the superuser; ya fig.Z - to the same, bottom view; figure 4 is the same longitudinal section.

A device for nasal electrophoresis of medicinal substances pc capacity 1, made of glass or acrylic plastic, in the front part of the container 1 is located behind the tap ropjjpBHHa 2; on the sides 1 there are lugs 3 dp for inserting an elastic with a ribbed surface of the flexible element 4 5; in order to secure the device to the patient's head; Two metallic cylindrical hollow electrodes 5 are attached to the bottom of the container 1 in such a way that the inner space of the E. Electrodes 5 is connected to the outer space outside the container 1; A clamp-contact jj b is placed on the bottom of the tank 1 in the gap between the outlet openings of both hollow electrodes 5 and connected by wires to the metal of the electrodes 5 and intended to connect a current source J in the upper part of the tank 1 two short truncated conical protrusions 7 are located through which pass out cylindrical electrodes 5 with a hygroscopic tubular lining. 8, the latter covers hollow electrodes 5 along their entire length. 25

The device works as follows. all at once ..

In the container 1 through the neck 2 pour the medicinal solution to the level, 1 / 2-3 / 4 capacity and close the hole -. kiT stopper. Then the electrodes 5, covered with a hygroscopic lining 8, are inserted into the nasal openings until the nasal ophthaloids are in tight contact with the skin with truncated conical tips 7 in the upper part of the tank 1. 5 In this position, the device is fixed on the patient's head using ribbed elastic of the flexible element I, which is threaded into the ears 3 of the container 1. The current source is connected to the terminal 6, 40 and the second pole is connected to the plate-electrode (not shown) placed depending on the technique on the back of the head or neck region. The medicinal solution is lifted up by the capillaries - (45 frames of the hygroscopic lining and reaches the depth of the nasal nasal cavity. Me.

re consumption of the drug solution in the absorbent lining, it is continuously replenished due to its receipt from the container. The internal diameter of the hollow electrodes (at least 5. mm) provides the patient with normal nasal breathing. Sterilization of the device is achieved by treatment with disinfecting solutions or boiling. Tubular hygroscopic elements before each procedure is subjected to washing, boiling and subsequent drying. Hygroscopic linings can also be used for single use.

The device for nasal electrophoresis provides increased ease of use and savings in drug substances.
