Description

 The invention relates to medicine, more specifically to a class of medical devices using the principle of electronic stimulation in physiotherapy.

 An electronic rectal-vaginal stimulator is designed to treat chronic constipation, prostatitis, enhance sexual potency in men, eliminate frigidity in women, cystitis, enuresis, hemorrhoids, etc.

 Known self-contained electrical stimulator (NPP), made in the form of a capsule, the body of which is divided into two parts, serving as electrodes, and inside is an electric pulse generator and a power source (ed. St. N 936931).

 The clinical use of nuclear power plants involves swallowing, introduction into the intestinal lumen during surgery, as well as rectal and through intestinal stomas. In all these methods, along with an unconditional positive effect, there are objective disadvantages consisting in the following: the lack of control of the device’s functioning during the procedure, the possibility of failure due to corrosion (due to prolonged exposure to a chemically aggressive environment), undesirable effects in actual the presence of diseases that limit the scope of the NPP (open wounds, peptic ulcer, etc.) that were not identified before the procedure, discomfort of the sterilization process of the NPP after his evacuation.

 Some of these drawbacks are eliminated in a technical solution protected by copyright certificate N 1223922, in which the transduodenal probe is a partially collapsible olive connected to an elastic tube. This design allows you to replace the batteries, while maintaining tightness, which is caused by a threaded connection and a silicone rubber o-ring. The electronic unit with the pulse generator microcircuit is made inseparable, which is a 19-bit binary divider with a control circuit and electronic components that ensure the selection of parameters of the generated pulses. This device, like the nuclear power plant by ed. St. N 936931, begins to function only in a conductive medium, but does not contain means of monitoring operability and, in addition, similarly to the indicated nuclear power plant, does not contain means limiting the amount of current flowing between the electrodes during the existence of stimulating pulses, which increases with an objective increase in the conductivity of the medium, which can cause discomfort in the patient.

 The proposed device, while maintaining the positive properties of the known above technical solutions, allows to eliminate these disadvantages. The closest analogue of the author. St. N 936931.

 To achieve this result, the electronic rectal-vaginal stimulator contains a pulse generator with a power source, a pulse generator power circuit breaker, a limiting resistor connected between the control input of the negative and the pulse generator power circuit, and a trip indicator connected between the control output of the pulse generator and minus the power supply bus, while the signal shaper is placed in a portable case with a removable cover and space but spaced from the electrode holder, one of the electrodes of which is connected to the output of the pulse generator, and the second to its control input, the pulse generator is configured to adjust the pulse repetition frequency, pulse duration, pulse train repetition period, number of pulses in the packet, and the electrode holder can be made in the form of a cylindrical rod with a rounded end, on the surface of which are placed ring-shaped electrodes of a given width in the form of a tablet, on the opposite sides of which p electrodes are arranged, or in the form of a baby's nipple with electrodes located on its conical part, and the operation indicator can be made in the form of an electro-acoustic transducer or LED, while the connection of the signal shaper with the electrode holder can be detachable.

 The drawing shows a structural electrical diagram of an electronic rectal-vaginal stimulator.

 The stimulator contains a signal shaper 1, a pulse generator 2, a power supply 3, a limiting resistor 4, a switch 5 in the pulse generator power supply circuit, a trip indicator 6, and an electrode holder 7 with two electrodes placed on it.

 The 2 pulse generator is made on microchips of the type 564 TM2 (BKO.347.064 TU1) and 564 LE10 (BKO.347.064 TU21), which are respectively a D-trigger and an AND-NOT circuit, using mounted resistors, capacitors and diodes located on circuit board in the housing of the signal converter 1. Hinged elements allow you to adjust the parameters of the generated signals.

 The power source 3 is two batteries of the type FL 2325 installed in holders mounted on the body of the signal former 1 to carry out the replacement.

 The switch 5 in the power circuit of the 2-pulse generator represents a miniature switch of the type ЦД 9-2 ОЮО.360.089, whose control element is brought to the outer surface of the signal conditioner housing.

 The actuation indicator 6, when executed in the form of an electro-acoustic transducer, is attached by the working surface to the inner surface of the signal conditioner housing to create an acoustic contact in it. As an element indicating the presence of pulses at the output of the pulse generator, an element piezoelectric-EP4D-17-1, ODO can be used. TU 712.017.

 When used as an indicator of operation of the LED, it is located on the body of the signal shaper with the ability to visually control the indicating surface.

 The electrode holder 7, on which the electrodes are placed, is made of PCB or high-pressure food polystyrene and, depending on the type of procedure, is a cylindrical rod 115-120 mm long, 12 ± 2 mm in diameter, a tablet with a diameter of 12 ± 2 mm or a case in in the form of a baby nipple (with a thickened end part). In all embodiments, the electrode holder should not have sharp edges. As the material of the electrodes can be used stainless steel 17X18H9, which has sufficient corrosion resistance.

 The signal generator 1 and the electrode holder 7 are spatially separated, and the connection of the electrode holder 7 with the housing of the signal former 1 can be detachable.

 Stimulator electronic rectal-vaginal works as follows. When the electrode holder 7 is inserted into the cavity between the electrodes, a conductive medium is created, as a result of which the switch 5 in the power circuit of the pulse generator 2 is activated, the pulse generator 2 is triggered, which causes the current to flow between the electrodes of the electrode holder 7, creating a voltage across the limiting resistor 4 connected to control input 2 pulse generator, thereby allowing the passage of signals to the indicator 6 operation, which creates sound vibrations with a frequency corresponding to or hydrochloric frequency pulses in the burst (in the case of an electroacoustic transducer) or light signals with a repetition period of the burst, when used as the indicator 6 trip LED (vibrations at a frequency of filling the pack, in this case not fixed due to the inertia of view).

 The limiting resistor 6 does not allow the current to exceed 500 μA, that is, eliminates the likelihood of unpleasant sensations with increasing conductivity of the medium.

The parameters of the signals of the 2-pulse generator are selected from the condition of the greatest efficiency of electrical stimulation and are:
-pulse duration 5-7 ms;
- pulse repetition period of 20-28 ms;
-pulse burst duration 300-450 ms;
-period of repetition of bursts 2500-3500 ms.

 The procedure time is 10 minutes in newborns, 20-30 minutes in adults. The holder 7 of the electrodes is inserted into the rectum to the depth of the metal electrodes, and in the form of a tablet is placed in the oral cavity (under the tongue). Procedures are performed daily or every other day. The course of treatment is 10-15 procedures. After the procedure, the holder 7 of the electrodes is sterilized.

 The compliance of the electronic rectal-vaginal stimulator with the requirements of medical practice in terms of functional qualities is confirmed by the prototype test protocols.
