Allowing at the same time as the drainage of the lesion, and prolonged the processing of drugs, this device, however, due to the presence of magnets and magnetic screen is quite difficult and cumbersome in execution.

You know Dre is therapy indications for abdominal surgery, proctology, gynecology, adopted as a prototype, is a hollow perforated forming element in the form of a body of rotation on the outer part of which is fixed to the cloth of the hydrophilic textile material coated with a complex of biologically active substances and biocompatible biodegradable polymer, provided with a latch input, the opposite input end of the device, and the ends of the napkins from the input end of the device is fixed with a safety thread, and the ends of the napkin with the opposite of stormy fixed clamp (EN, application No. 2001127293, MKI A 61 L 15/64, Paul. Resch. from 26.09.2002).

However, allowing prolongirovanne to bring drugs into the zone of abdominal diseases while ensuring the removal of the decay products of the pathological focus, this device is time-consuming to manufacture ethnologica and has insufficient permeability for gas and exhaust detachable from the side of the input end.

The present invention solves the problem of creating a more efficient, easy to manufacture and technological drainage device with a prolonged therapeutic effect, with good quotedata is solved by in the device with a bioactive coating for drainage and prolonged local drug therapy, is a hollow perforated forming element in the form of a body of rotation on the outer part of which is fixed to the cloth of the hydrophilic textile material applied thereto, at least one layer of a complex of biologically active substances and biocompatible biodegradable polymer, it is new that the ends of the napkins folded into the inside of the shaping element and secured within it by means of the rings of elastomer.

Such fixation of tissues with prolonged therapeutic effect on the forming element allows not only to carry out the drainage direct contact with biologically active substances with diseases and dosed prolonged their income, but also makes the device less traumatic and more simple in manufacture and in use. At the same time increases the efficiency of the device due to good through the detachable cross in his way.

It is most convenient to perform a formative element of elastomers permitted in medicine. At present lie is more complete sorption detachable inside shaping element can be located filler.

Currently, the most commonly used:

as hydrophilic textile material, which is the basis napkins with prolonged action, woven or non-woven fabric of cotton, rayon or a combination thereof;

as biocompatible biodegradable polymer carboxylmethylcellulose, alginate or polysaccharide.

Biologically active coating, depending on the nature and extent of the affected area may contain antimicrobial, and/or hemostatic and/or anaesthetic and/or antioxidant and/or a wound healing agent.

To improve drainage napkin can be done perforated.

The supply device to the output end of the fixing element is made of elastic material, enables you to control the depth of penetration into the affected area and protect from dropping the device into the affected cavity. The form of this element can be any appropriate functions mentioned above.

From the output end of the shaping element fixed pin thread that insures its excretion from the affected cavity, which may be located both inside and outside of the shaping element.

The claimed design ustroystvo made in the VLR shaping element in the form of a hollow cylinder 1. On the outer part of the hollow cylinder 1 is fixed biologically active coating consisting of wipes 2 of textile material with hydrophilic properties coated with a complex of biologically active substances and biocompatible biodegradable polymer, and the ends of the napkin 2 is fixed inside the hollow cylinder 1 by means of the rings 3 of elastomers. On the output end of the hollow cylinder 1 can be fixed locking element 4, made of an elastic material, permitted in medicine

Inside Polota cylinder 1 can be located filler 5 (Fig.2), and from its output end can be fixed pin thread 6 (located inside Fig.1 or from the outside Fig.2) of the hollow cylinder 1.

The proposed device operates as follows. Before use, the napkin 2 is quenched, and the device is inserted into inflamed cavity, in the case of treatment of proctologic diseases, it is desirable to lock the locking element 4. When the locking element 4 prevents the disappearance of the entire device in the affected area.

In the case of treatment of gynecological diseases when wet wipes 2 the device is inserted into the vagina completely, leaving outside only vaustralia can provide both passive drainage with therapeutic action, obespechivaiut biologically active coating, and in the mode of active drainage from the connection circuit, which feeds into the unit additional biologically active fluids and medicines from outside.

In case of heavy use allocations forming element in the form of a hollow cylinder filled with a filler for sorption detachable 5 (granules, gauze, cotton wool, non-woven fabric). Deleting devices using the lead of the thread 6 or the locking element 4 is produced depending on the nature of the disease. With copious discharge at least 2-3 times a day, in the absence of discharge, depending on the physiology of the patient, as the flow of biologically active substances from the tissues 2, impregnated with a therapeutic substance, is as biodegradation containing polymer, i.e., about 3 days.

This ensures the most prolonged contact of the drug substances with a pathological focus, which helps to reduce the time of treatment.

The effectiveness is confirmed by the use of an experimental batch of the above-described devices for the treatment of hemorrhoids, fissures, active drainage cavities in the postoperative lane and active surfaces for drainage and prolonged local drug therapy, representing a hollow perforated forming element in the form of a body of rotation on the outer part of which is fixed to the cloth of the hydrophilic textile material applied thereto, at least one layer of a complex of biologically active substances and biocompatible biodegradable polymer, characterized in that the ends of the napkins folded into the inside of the shaping element and secured within it by means of the rings of elastomer.
