Abstract

Usage: for galvanization and electrophoresis in gynecology. The inventive inside a hollow cylindrical closed at the working end with the handle of the housing is a hollow metal rod with a lead plate fixed on it, used as an active electrode and as a channel for supplying a drug substance. Throttle holes are made in the wall of the distal end of the electrode body opposite the lead plate, through which ions of the drug substance have a locally directed effect on the site of inflammation. 1 ill.

Description

Ј

The invention relates to medical equipment, in particular to devices for electrophoresis and galvanization.

The purpose of the invention is to reduce the morbidity of manipulation due to locally directed exposure to a drug substance, and to reduce doses of physical energy.

The drawing shows an endovaginal electrode for galvanization and electrophoresis of drugs in section.

The endovaginal electrode for galvanizing and electrophoresis of medicinal substances consists of a hollow cylindrical enclosed at the working end of the housing 1 with a hollow metal rod 2 installed inside, on which a lead plate 3 is mounted. At the working (distal) end of the electrode housing 1 there are throttle openings opposite the plate 3 4. A channel is made in the handle 5 of the electrode connecting the rod 2 with the cannula 6 for the syringe. A limiter 8 is installed along the handle 5 with the possibility of moving and fixing with the latch 7. A transverse hole is also made in the handle 5, in which, for example, on a thread, a terminal 9 is mounted for connection to a current source.

The endovy end electrode for galvanizing and electrophoresis of drugs works as follows. A syringe is inserted into cannula 6 and a drug solution is introduced until the electrode cavity is filled. The electrode is inserted into the vagina with a closed cannula 6. The patient is rotated on the right side by 35-40 °, while the throttle holes 4 are set00

right and left in the vaults of the vagina, depending on the position of the patient. In this case, a solution of the drug substance does not flow into the vagina. After that, the limiter 8 is installed at a predetermined distance from the end of the body and secured with a latch 7. A second lead plate electrode is placed on the front abdominal wall in the right and ninth iliac regions or on the sacrum region on the right or left, depending on the location of the inflammation site (chronic adnexit or parametritis on the right or on the left). Through terminal 9, the electrode is connected to the apparatus. In this case, the ions of the drug substance through the throttle openings A upon contact of the solution with the vaginal wall are diffusely transported to the paravaginal and parametric tissue, where the nerve plexuses {pi. literovaglnalis) and vessels (arteries and veins) of the internal genital organs. Diffusing through the walls of blood vessels, drugs enter the bloodstream and are delivered to the uterus and appendages. At the same time, a locally directed effect of the drug substance is ensured by the use of small doses of physical energy during physiotherapy (up to 2 mA) of chronic adnexitis, parametritis, endomyometritis.

The following example illustrates the implementation of endovaginal electrophoresis using the proposed electrode.

Shch-va I.V., 36 years old, was in the gynecological department from 10.24.89 to 11.11.89., Medical history No. 1541.

Clinical diagnosis: chronic bilateral adnexitis, chronic endometritis. In the analysis of the smear from the cervical canal and the urethra before treatment (10.23.89) - leukocytes are completely in the field of vision, after treatment (09.1 1.89) - 3-5 leukocytes in the field of vision are single epithelial cells. Bakseeding from the cervical canal - green streptococcus 10bCOE (before treatment), after treatment - epidermal staphylococcus - moderate growth. The result of a histological examination of endometrial aspirate before treatment: chronic endometritis, after treatment there is no data for endometritis. Bimanual study data before treatment: uterus of normal size, sensitive to

palpations, appendages in the form of painful aches. After treatment, the uterus is painless, stiffness in the area of the appendages decreased. 15 sessions of endovaginal

electrophoresis with a 25% solution of dimexide and lidase 64 units, using the proposed electrode. The duration of the procedure is 20 minutes with a current strength of 1.5 mA (through the right and left vaginal arches). There were no complications after the procedure.

It should be noted that to date, vaginal electrophoresis has not been widely used in gynecology due to frequent complications, burns of the vaginal mucosa and cervix, dry necrosis. Designs of known electrodes provide maximum contact with the vaginal mucosa 2. More than 600 procedures have been performed using the proposed electrode, and no complications have been obtained. The electrode was used in women with chronic endometritis and chronic bilateral salpingoophoritis - from 10-15 sessions for 10-20 minutes (in the first phase of the menstrual cycle) with a current strength of 1.5-2.0 mA.

Tests of the proposed design of the electrode showed its advantages over the known ones (which consist in providing a locally directed effect of the drug substance on the inflammation site and the use of lower doses of physical energy, which leads to a reduction in the morbidity of manipulations. It should also be noted that medicines are saved when using the proposed electrode.
