SUMMER COVER WITH SOLE

ON THE EXTERNAL FIXING DEVICE

The utility model relates to medicine, namely to auxiliary technical means, can be used as a reusable protective agent in the treatment of an external fixation device for walking in the warm season and when moving in a building.

Treatment of bones with transosseous osteosynthesis involves the use of external fixation devices that are installed on the bare extremity, while bone fixators, knitting needles or bone screws come out of the bone directly through soft tissue. Regardless of the time of year, in order to provide favorable conditions for the restoration of a damaged limb, patients are shown motor activity, an early functional load on the operated limb. External fixation devices (hereinafter referred to as AVF) allow the patient to load the limb several days after the operation, allow walking, with additional means of support (crutches), indoors and outdoors. During outdoor walks in the summer season, when the air temperature on average is in the range from plus 25 ° to 28 ° C (degrees Celsius), it can drop to plus 18 ° C and rise to plus 40 ° C exposed to the environment (sunlight, wind, dust, thermal effects of the external environment, vulture, etc.), which can lead to adverse effects. At the same time, in the summer there are many insects (midges, mosquitoes, flies, etc.) in the environment that are active. Therefore, it is necessary to limit this effect, and for these purposes, covers of various designs are used.

Known hygienic cover disposable on the Ilizarov apparatus (source [1]: patent RU 126905). The hygienic cover [1] is made of a “breathable” waterproof material laminated from the outside with a plastic film, together forming a soft flexible canvas. A braid is sewn along the upper and lower bent edges of the cover to tighten the edges. The right and left edges of the case are equipped with Velcro fasteners. The cover is equipped with strips of water-absorbing (water-absorbing) material, preventing the penetration of water into the cover, located at the edges and along the edge of the Velcro. The cover [1] is disposable and is intended for use while patients are taking a shower during treatment.

This analogue [1] is intended for indoor use, structurally unsuitable for foot protection, does not provide effective protection of the limbs from mechanical and thermal effects of the environment, does not involve reusable use, and is not able to provide the best microclimate inside the case when walking on fresh air in the summer season, when the air temperature on average is in the range from plus 25 ° to 28 ° C (degrees Celsius), it can drop to plus 18 ° C and rise to plus 40 ° C. A device for connecting the edges of a flexible web made in the form of Velcro fasteners when used outdoors quickly fails due to degradation of the felt side and clogging of the side with micro hooks. The analogue [1] does not contain a supporting surface protecting the foot from mechanical damage.

Known case insulated on the external fixation device for the foot reusable (source [2]: patent RU 174651). It is made in the shape of a sleeve, with one closed end or a “boot” made of flexible fabric, contains a zipper on the side surface, an elastic sole and protects the foot from mechanical and thermal effects when walking. A flexible fabric consists of an outer layer made of windproof moisture-proof vapor-permeable fabric, an inner layer made of vapor-permeable insulation and a soft vapor-permeable hypoallergenic substrate made of a non-woven textile fabric. The fabric of the outer layer consists of cotton fibers with a polyamide coating (cotton raincoats with water-repellent impregnation, cotton + synthetics) with a water resistance of 8,000 to 10,000 mm water column and vapor permeability of 6,000 to 8,000 g / m2 / 24 h. The inner layer is made of non-woven material based on structured polyester fibers (synthetic winterizer 300 g / m ² , holofiber) with a thermal conductivity of not more than 0.039 W / (m⋅ ° C). The layer of soft vapor-permeable hypoallergenic substrate is made of vapor-permeable non-woven knitted fabric (fleece).

This analogue [2] is intended for use in the winter, at air temperatures below minus 5 ° C, for this it has a three-layer flexible cloth containing an inner layer of insulation in the form of a non-woven material based on structured polyester fibers (synthetic winterizer 300 g / m ² , holofiber ) with a thermal conductivity coefficient of not more than 0.039 W / (m⋅ ° C). When used in summer, a three-layer flexible cloth, with a layer of syntepon, leads to overheating of the limb, causes discomfort to the patient and the formation of sweat on the limbs under the cover, which is an undesirable phenomenon, as it promotes the growth of microorganisms, bacteria.

Known protective and cosmetic coating for external fixators (source [3], patent US 7887495), involves use in both cold and warm climates. The coating [3] is made of soft, washable, waterproof fabric, made of vinyl, neoprene or nylon, in shape and size corresponding to the shape and size of a limb segment, including the shape of a “boot” and designed to protect the lower leg and foot. It contains a cord threaded into the fabric to tighten the upper edge of the cover, and an opening is formed in which the lower leg passes. Contains a device for connecting the edges of the fabric of the cover, in the incision area, made in the form of Velcro or lacing. Contains window inserts with ventilation holes or pockets for installing a fan.

Coating [3] does not provide comfortable and safe use in the summer, when the patient is exposed to sunlight, for example, when relaxing on the beach or in nature. The analogue uses synthetic waterproof fabrics that do not provide free air circulation indoors or outdoors in the summer. The design includes windows and pockets for forced ventilation. The removal of vapors and counteraction to the greenhouse effect due to open ventilation openings, a mesh screen, a fan, open direct air flows are not hygienic, microscopic particles contained in the air, including infectious agents, and vagus, can also penetrate into openings, which can lead to a deterioration of the patient's condition. With prolonged contact with the skin, synthetic tissues can cause irritation and sweat. In order to provide the limbs with a comfortable microclimate, to avoid overheating from warm sun exposure, to avoid condensation of moisture, fumes, on the limbs and parts of the apparatus, the properties of the cover materials should differ from the properties of the materials used in the autumn or winter. Also, to ensure comfort, the material should be light, should reflect as much solar radiation as possible, which is not provided for in the analogue [3]. The coating [3] does not contain a sole, a supporting surface for the foot, it is assumed that the supporting surface for the foot is equipped with an AVF. Velcro fasteners when used outdoors quickly fail, due to degradation of the felt side and clogged side with hooks.

Thus, the well-known covers are not suitable for comfortable and safe use on the foot and lower leg for walking in the fresh air in the summer by patients who are not able to wear shoes on the foot. Known covers [1; 2; 3] poorly provide safe air circulation, heavy, not enough reflect solar radiation.

The technical result consists in providing protection of the tibia with foot, recorded in the AFF, from the negative effects of the environment in the summer season, ensuring a safe microclimate under the cover. The cover is lightweight, does not allow overheating of the extremity and eliminates temperature fluctuations, provides thermal and mechanical protection of the lower leg and foot, creates a barrier to infectious agents in the air, dust, sediments, and also avoids the "greenhouse effect".

The technical result is achieved by the fact that the summer cover with a sole on the external fixation device (hereinafter referred to as the cover) is made of flexible fabric, contains a braid in the upper part, a fastener made on the side surface. It differs in that it contains an elastic sole in the lower part, the flexible fabric is made in one piece, made of soft "breathable" hypoallergenic cotton-containing fabric, the fastener is made in the form of a zipper.

Provided that the flexible sheet is made of white fabric, the mass density of the tissue 40 to 315 grams per m ^2, and the flexible sole made of thermoplastic rubber. It is envisioned that the flexible web is made of fabric based on 100% cotton fibers. It is envisaged that the flexible fabric is made of fabric based on cotton fibers with a synthetic fiber content of not more than 20%. It is envisaged that the flexible fabric is made of fabric based on cotton fibers with a synthetic content of not more than 80%. It is envisaged that the cover is made in the form of a hollow cylinder with a bottom, with a braid in the upper part and a zipper on the side surface. It is envisaged that the cover is made in the form of a boot with a braid in the area of the shaft and a zipper on the side surface, the braid is made in the upper part of the cover in the form of a flat lace mounted with the possibility of movement in a flexible fabric. It is envisaged that the cover has an armhole in the upper part for the passage of parts of the external fixation apparatus and the cover to fit the limb.

The utility model is illustrated by graphic materials.

The objective of this real utility model is the development of a lightweight case for the movement of patients during treatment with an external device  fixations that do not have the ability to wear shoes on the operated limb in the warm season and while in the building.

A summer cover with a sole on the external fixation apparatus is made of flexible fabric, contains a braid 1 (Fig. 1; 2; 3) in the upper part, a zipper 2 (Fig. 1; 2; 3), made on the side surface and an elastic sole 3 (Fig. 1; 2; 3) in the lower part. The flexible fabric is made of a soft, single-layer, hypoallergenic cotton-containing fabric made from a "breathable" (providing appropriate heat transfer, air exchange and exhaust vapors). It is assumed that the flexible sheet is made of white cloth on the basis of 100% cotton fibers, a mass density of from 40 to 315 grams per m ^2, and the flexible sole made of thermoplastic rubber.

The cover is preferably made in the form of a hollow cylinder with a bottom (figure 1; 2), with a braid 1 in the upper part and a zipper 2 on the side surface. It is permissible if the flexible fabric is made of fabric based on cotton fibers with a synthetic fiber content of 20% but not more than 80%. The cover can also be made in the form of a boot (Fig. 3) with a braid 1 in the area of the shaft and a zipper 2 on the side surface, the braid 1 is made in the upper part of the cover in the form of a flat lace mounted for movement in a flexible fabric, also in the ankle region can also be installed additional braid 4 (figure 3), to enable adjustment of the size of the cover. The cover for the passage of parts of the external fixation apparatus and tight fit to the limb may have an armhole in the upper part (not shown in the photographs).

The cover provides appropriate heat transfer, air exchange and exhaust vapors to create a favorable microclimate inside the cover. The white fabric of a single-layer cotton-containing flexible fabric reflects part of the solar radiation (unlike dark-colored fabric, for example black), allows air to circulate through it, and at the same time filters the incoming air. The cover, when used, is hermetically worn on the limb and does not allow dust, a vulture, etc. to penetrate into the cover. The cover can be made personally of different sizes depending on the size of the limb segment, for example, for children or adults.

The cover is used in the summer season, when the air temperature on average is in the range from plus 25 ° to 28 ° C (degrees Celsius), can drop to plus 18 ° C and rise to plus 40 ° C as follows.

The cover is put on the foot and wrapped on the shin with the installed AVF. Open ends wrap around the limbs. Fasten the zipper 2 by pulling it on the lock. Pull the loop 1 and the edges of the cover in the form of a loop, tighten the limb, provides a snug fit of the flexible web to the skin, the inner space of the cover becomes airtight and air can circulate only penetrating through the fabric of the flexible web. The edges of the tape 1 are tied or fixed with a lock-latch installed on it. During operation (a walk in the warm season and in the building), an elastic profiled rubber sole provides mechanical protection of the foot. The cotton fabric of the flexible fabric allows fumes to be removed from the surface of the limb, does not cause discomfort from the contact of the cover with the skin, does not cause irritation, absorbs sweat and allows the skin to “breathe”. The cover protects the limb from sunburn, dust, dirt, and insect bites. Depending on the design of the AVF, the cover may have an armhole for comfortable placement of the cover on the device and limbs. When cutting the cover, the different heel and toe heights are also taken into account. A boot-shaped case may have additional straps along the length of the toe to create the most comfortable form of the case. Patients have the opportunity of safe movement on the street in the warm season and in the hospital. Reusable cover, hand and machine washable.

The claimed technical solution is made and applied by the applicants in the treatment of patients in the Ilizarov Center of Kurgan.
