Abstract

The disposable medical bandage contains the transparent moisture-proof film in a shape of the ring of the adhesive plaster with the attached flexible ring containing the strips for stick fasteners andthe additional extension for binding. At the top base of the ring, the deformator designed as the goffered ring is attached with the eccentric microporous absorbing cotton-and-gauze layer inside. The deformator is overlaid by the cover composed of two parts. The lower transparent plastic part of the cover contains the holes for air that may be protected by the cloth mesh. The upper dome-shaped part is able to rotate relative to the lower one. The focusing plastic lens with the air-permeable holes is installed in the center of the upper part. The air-permeable holes open upon being aligned withcorresponding holes of the lower part. The design of the both parts of the cover allows for their self-fixation in both closed and open positions with the aid of the extensions on the outer surface of the lower part and the hollows on the inside surface of the upper part. Another design of the medical bandage is possible. Namely, the bandage comprises the base with the airproof cotton-and-gauze ring inserted into the flexible ring containing the strips for attaching to the body with the stick fasteners. The cylindrical cover is made from the elastically deformed material with the absorbing cotton-and-gauze layer inside. At the top, the cover ends with the transparent plastic plate containing the valve.

Description

The invention relates to medicine, namely, to means of protection and treatment of open wounds, frostbite, burns, skin diseases, purulent wounds after their dissection and postoperative sutures.

A known bandage having several layers of dressing material, under its surface layer are placed elastic tubes with holes in the side surface, directed towards the working part of the bandage and spacers made of dressing material, located between the tubes |As. USSR Me1232251, IPC: Ab1E13/00, publ. byul. Mme19, 1986.1.

The disadvantage of the analogue is direct contact with the affected parts of the body, which causes pain and injury during application and removal, air and daylight do not reach the affected areas, which, when lymph, blood, pus is released from the wounds, creates a favorable environment for the development of purulent-inflammatory processes , impossibility to visually monitor the treatment process without removing bandages, difficulty in use, long process of rehabilitation of patients.

The closest in terms of technical essence is a bandage that has a membrane made of a thin transparent moisture-proof film with holes for fittings, the membrane is made of two layers, air cavities in it alternate with strips of electrically conductive material (AS USSR Mo402366, IPC: Ab1TE13/)), published Bull. Mo42, 1973 |.

Disadvantages of the prototype are direct contact with the affected areas, impossibility of free access of air and sunlight and control over the course of treatment, difficulty in use.

The technical task is to create a single-use medical bandage, through a constructive solution and the use of transparent and airtight hermetic materials, to avoid direct direct contact with the wound tissue, to avoid the danger of ingress of pathogenic bacteria from the outside, which will make it possible to suck and collect purulent secretions, and will be easy to use and will speed up the process of treating wounds, burns, frostbite, skin diseases, purulent wounds and postoperative sutures in patients.

The given technical task is solved by a single-use medical bandage, which consists of a moisture-proof film made in the form of a ring of sticky plaster, surrounded from the inside by a layer of microporous cotton-gauze absorbent material, which is fixed by a plastic flexible ring equipped with Velcro strips and a protrusion for additional fastening using a sticky patch (if necessary), in addition, a deformer in the form of a corrugated ring is attached to the upper base of the ring, which (the deformer) is also covered from the inside with a cotton-gauze absorbent layer, a two-part dome is attached above the deformer: the lower one is cylindrical the transparent part of the dome is made of plastic with air-permeable holes protected by a fabric mesh (or without it for some versions) to reduce the ingress of dust, the upper part of the dome is plastic, transparent with a focusing plastic lens in the central part and also made with air-permeable holes and with the possibility of rotation on the lower part of the dome so that the ventilation holes can be closed and opened when necessary. A focusing plastic lens in the upper part of the dome of the disposable medical bandage serves to better focus and collect sunlight and daylight. After fixing the disposable medical bandage on the patient's body, by turning the upper transparent part of the dome with holes and the focusing lens 60 degrees to the right, the ventilation holes are opened. The top part of the dome is self-locking in the closed or open position by means of protrusions on the outer surface of the lower part of the dome and cells on the inner surface of the top part of the dome of the medical dressing.

Disposable medical bandages are made with the possibility of opening and closing holes to prevent water, dust, and cold air from entering.

An eccentric (thickened on one side) layer of microporous absorbent material is used to collect purulent secretions, while the bandage is attached to the patient's body with the thickened layer down, and an additional protrusion for attachment - up, to enable discharge to flow onto the thickened part of the absorbent layer.

A variant of a single-use medical bandage is a single-use suction medical bandage, which is used for the treatment of purulent wounds, namely, for extracting (sucking) purulent secretions from a wound and venom after a snake bite.

The disposable absorbent medical bandage consists of a base consisting of a cotton-gauze airtight ring attached to a flexible plastic ring equipped with elastic strips for attaching to the patient's body with Velcro, a dome in the form of a cylinder, made of elastic deformed (corrugated) silicone rubber, covered from the inside with an absorbent cotton-gauze layer, in the upper part of the dome is closed with a transparent plastic plate with a valve that serves to maintain the vacuum in the capsule, the valve in the working position is closed.

Disposable medical bandages of the following geometric shapes are produced: round, oblong, ellipsoidal, rectangular, as well as in the form of a pyramid of certain geometric dimensions in accordance with the specifics of placement on the surface of the patient's body, deformed rubber to give the disposable medical bandage the shape of the damaged surface on the patient's body.

The essence of the invention is explained by the figures of the graphic image, where in Fig. 1 - a general view of a disposable medical bandage, in Fig. 2 - a general view of a disposable medical bandage - side view, on the left - a top view, on the right - a cross-sectional view from the inside, on Fig. 3 - section AA from Fig. 2, in Fig. 4 - a general view of a disposable medical bandage for postoperative sutures and linear injuries, in Fig. 5 - a general view of a disposable medical bandage with a flat dome for minor wounds (non-purulent wounds), in Fig.b - a general view of a single-use suction medical bandage, on the right - a side view, on the left - in a section from the inside, in Fig.7 - a general view of a single-use suction medical bandage with a compressed deformation part, i.e. in working position.

The disposable medical bandage consists of a ring of adhesive patch 1, surrounded from the inside by an eccentric layer of microporous cotton-gauze absorbent material 2, which is fixed by a plastic flexible ring 3, equipped with Velcro strips 4 and a protrusion 5 for additional attachment to the patient's body with sticky plaster (if necessary), on the upper base of the ring 1 a deformer b is fixed, which has the appearance of a corrugated ring, which is also covered from the inside with a layer of cotton-gauze absorbent material 2, a two-part dome is placed above the deformer: the lower 7 and upper 8, the lower transparent the cylindrical part of the dome 7 is made of plastic with air-permeable holes 9 protected by a cloth mesh to reduce the ingress of dust, and the upper part of the dome 8 is plastic transparent with a focusing plastic lens 10 in the central part, the upper part of the dome 8 is made with air-permeable holes 9 and with the possibility turning on the lower part of the dome by 60 g radii so that the ventilation holes can be opened or closed as necessary. The upper part of the dome is self-fixed in the closed or open position with the help of protrusions 11 on the outer surface of the lower part of the dome 7, and cells 12 on the inner surface of the upper part of the dome 8 (fig. 2, 3)

The disposable absorbent medical bandage consists of a base 1, consisting of a flexible plastic ring 2, to which a cotton-gauze airtight ring is attached and a dome C in the form of a cylinder made of elastic deformed silicone rubber, covered from the inside with an absorbent cotton-gauze layer 4 , in the upper part, the dome is closed with a transparent plastic plate 5 with a valve 6, in addition, a flexible plastic ring 2 is equipped with elastic strips 7 for attaching to the patient's body with Velcro (fig. b, 7).

The disposable medical bandage works like this.

After the bleeding from the wound has stopped in the case of burns, frostbite in certain parts of the body, in various purulent-inflammatory diseases after their dissection, and after applying sutures, the wound is treated with medicinal drugs, and a disposable medical bandage is selected according to the following characteristics:

By the amount of damage to the body surface (diameter of the wound).

According to the form of damage (straight cuts, burns, postoperative stitches).

According to the shape of the damaged parts of the body. (In industrial production, all single-use medical bandages will be conventionally numbered in accordance with the sizes and shapes of individual parts of the human body).

After removing the disposable medical bandage from the sterile polyethylene package, remove the protective film from the adhesive patch 1, clean the periphery of the damage with an antiseptic solution, and attach the disposable medical bandage to healthy tissue with the help of adhesive patch 1. If there is a need for more reliable fixation of the medical bandage bandages on the patient's body, then use an additional fastening protrusion 5 and attach to the patient's body with a strip of sticky plaster. After fixing the medical bandage on a certain part of the body, by turning the upper part of the dome 8 with holes 9 and the focusing lens 10 by 60 degrees to the right, the ventilation holes 9 are opened.

An eccentric (thickened on one side) layer of microporous absorbent material 2 is used to collect purulent secretions, and the single-use medical bandage is attached to the patient's body with the thickened layer downwards, and the additional protrusion 5 for attachment is upward, so that the purulent discharges under the action of the earth gravity flowed to the thickened layer 2.

A single-use suction medical bandage is attached to healthy tissue by applying 1 adhesive substance to its base, which is in a separate small container together with a suction medical bandage in a sterile package. Then they are additionally fixed with the help of elastic strips on Velcro 7, after which, by pressing on the cover of the bandage 5, they compress it and "flatten" it, putting it in the working position (fig. b, 7). The valve in the cover serves to maintain the vacuum in the bandage and is closed in the working position. Elastic deformed rubber, trying to return to its original position, creates negative pressure, which in turn will be compensated by purulent discharge from the wound. In addition, purulent secretions will be absorbed by the microporous absorbent layer applied to the inner surface of the absorbent disposable medical bandage.

Information that confirms the possibility of implementing the invention.

A comparative evaluation of the effectiveness of the therapeutic effect of the proposed disposable medical dressings was carried out on two groups of patients (5 in each) with carbuncles of different localization. The time of wound cleaning, body temperature, and the time of appearance of granulation served as indicators for evaluating effectiveness.

In the 1st group, after dissecting the purulent focus and washing the wound with an antiseptic solution, medicinal preparations were applied to the wound surface using ordinary cotton-gauze bandages (control group).

In the 2nd group, after surgery and treatment of the wound with drugs, disposable medical bandages according to the proposed invention were used.

The test results are given in Table 1.
