Description

The invention relates to medical equipment and is intended for ionization and iontophoresis of mucous membranes with silver ions, without using external sources of electric current.

Silver ions have antimicrobial and astringent properties. These properties are used in medicine, including for the prevention of colds - rhinitis.

The invention is known "Antimicrobial ionizer and method for preparing a therapeutic solution" (RF patent No. 2190573). The ionator contains a short-circuited anode and cathode made of metals with various electrochemical potentials - silver and gold. An ionized solution prepared using an ionizer can treat the mucous membranes of the nose with silver ions. The disadvantage of an ionizer is that it cannot be used directly on the mucous membranes. In this regard, the effectiveness of the known method is not high.

Prolonged ionization can provide a bimetallic applicator for physiotherapy, containing two electrodes of metals with different electrochemical potentials (RF patent No. 2149623). Between the electrodes of the applicator there is a cavity into which a hydrophilic insert is inserted. The liner may be impregnated with a solution of, for example, a silver salt. The disadvantage of the applicator is that it is structurally not intended for ionization inside the nasal passages, and therefore it is impossible to prevent rhinitis with its help.

A device is known - a nasal dilator (US 2009101139 A1, 04/23/2009). The dilator is a design in the form of a split ring-holder of the stimulator with electrodes that are placed in the nasal passages for stimulation to facilitate nasal breathing. The disadvantage of this device is that with its help it is impossible to carry out iontophoresis with silver ions using the energy of the difference in electron yield, which would allow the device to be used for almost unlimited time. For the stimulator to work, the dilator needs additional sources of electricity, the duration of which is limited in time. Dilator power sources require periodic replacement. In fact, the well-known dilator is not one but two devices, each with its own independent power supply, which are located at different ends of the holder. Iontophoresis of the mucous membranes, simultaneously of both nasal passages, is possible if both devices are turned on simultaneously. Thus, the effectiveness of the well-known dilator, compared with other prototypes, for example, a physiotherapy device (RF patent No. 2215555), is provided by a simple combination of two devices, each of which, individually, does not have inventive advantages over the known physiotherapy device.

A device and method for physiotherapy (RF patent No. 2215555) is a prototype. The device contains two short-circuited electrodes for contact with the secrets of the skin or mucous membranes, while the electrodes are made of metals with different electron work function values. Using the known device, it is possible to ionize the nasal passages, including silver ions. The disadvantage of this device is that with its help it is impossible to carry out iontophoresis simultaneously from both nasal passages.

The present invention solves the above disadvantages. With its help, it is possible to carry out prolonged iontophoresis with silver ions of both nasal passages at the same time.

To implement the proposed device it is proposed to perform in the form of a split ring of elastic material. Such a material can be a metal recommended for contact with human skin, for example: silver, gold, stainless steel. It can be a metal-coated plastic. At the ends of the split ring are electrodes in the form of balls with a diameter of about 4-5 mm. If the structure is not made of precious metal, it is covered with a metal film of fine gold or silver. Moreover, if the coating is gold, one of the electrodes is additionally coated with silver. If the coating is silver, one of the electrodes is coated with gold. Since the ball-electrodes are spatially spaced from each other, this allows you to enter them into the nasal passages separately - one electrode on the right and the other on the left. In which particular nasal passage one or another electrode is located does not matter.

To use the proposed device, for the prevention of rhinitis, its electrodes are placed in the nasal passages, so that they are separated by a nasal septum. In places of contact with the mucous membranes, the electrodes are retained due to the elasticity of both the septum tissue and the elasticity of the split ring.

The use and design of the invention are illustrated in figures 1 and 2, where:

1 - silver electrode; 2 - a gold electrode; 3 - split ring.

Upon contact of two dissimilar metals with the mucous membranes of the nasal passages, silver ions are released from the silver electrode, where the electron yield is lower. This phenomenon is known as contact potential difference. Silver ions rush towards the gold electrode, where the electron yield is higher. There is iontophoresis of the mucous membranes. As a result, silver ions have a detrimental effect on pathogenic microorganisms and form metal-protein compounds with the proteins of the mucous membranes. These compounds have astringent properties, which helps to reduce mucous secretions.

The proposed device can be used both without time limitation, and for several hours, for example, during a night's sleep. In our experiments on volunteers, 8 hour applications showed that the concentration of silver ions in the mucous secretions increases during the first 4-6 hours and reaches values from 0.017 to 0, 044 mg / l. After which the concentration reaches the saturation point, and the ionization process stops. This is enough to obtain a preventive effect, without exceeding the maximum allowable metal concentrations. The difference in the values of ion concentrations can be explained by the individual characteristics of the volunteers, some differences in the composition and pH values of the secrets of the nasal mucous membranes.

The effect of the invention was studied on volunteers - students of Moscow University. M.V. Lomonosov. The experiment involved 74 people, aged 17 to 22 years. Volunteers were divided into two groups - experimental and control, 37 people in each group. In the autumn-winter period - November and December, for 50 days, volunteers installed devices in the nasal passages daily, before going to bed. In the morning, after sleep, the devices were removed. At the end of the experiment, the number of volunteers suffering from rhinitis was calculated over the entire experimental period. In the control group there were 14 such people; in the experimental - 5 people. Based on these results, it was concluded that the proposed device is effective for the prevention of rhinitis.
