SUMMER CASE ON THE EXTERNAL FIXING DEVICE

The utility model relates to medical devices, can be used as a reusable protective agent for treating bones with an external fixation device for walking in the warmer months and when moving around the building, as well as an additional means of hygiene of the operated limb under clothing and inside a winter warmed cover.

Treatment 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. In this regard, there is a need for sanitary and hygienic protection of the operated limb with an installed external fixation device (hereinafter referred to as AFF) from the negative impact of the external environment. For this purpose, use protective hygienic covers.

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 not suitable for reusable use, the cover material does not allow multiple washing, drying, thermal disinfection. 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.

Known protective cover (source [2]: patent RU 95514) made of a single layer soft flexible fabric, woven or non-woven material providing free air circulation, containing fixing means on two opposite (closable) sides of the fabric, made in the form of a zipper, which allows to hold the web is in a rolled state, a tightening element in the form of a cord passed into the channel along the edge of the web (braid), providing a retraction of the cover for its tight adjunction to the limb. The channel for the cord is formed by the fact that the canvas is bent and stitched along the edge where the tightening element is located. The canvas has two tightening elements located on opposite sides of the canvas and providing a tight attraction of the cover to the limb from two opposite open sides. The cover can be made in the form of a sleeve with two braids or in the form of a boot for placing the ankle joint and foot closed on one side and having a braid in the area of the shaft. The canvas for the case in the form of a sleeve in the expanded state has the shape of a rectangle. The canvas for the boot-shaped cover in the unfolded state has this shape when folded which forms the boot, so that on one side the fabric is stitched with the formation of a seam in the foot area. The seam has a free allowance that excludes the appearance of open areas at the places of divergence or loose contact of the edges of the cover.

The protective cover [2] refers to barrier medical devices and involves the protection of the patient’s operated limb from the penetration of dangerous organic contaminants (bacteria, fungi, viruses, prions, parasites, insects, etc.) and inorganic nature (dust of metals and their oxides, various minerals , inorganic salts, plastics, synthetic fibers, etc.). Woven or non-woven material, cloth analog [2] does not have the necessary properties. The material of the canvas, in order to protect the limbs, the possibility of reusable comfortable use, in addition to ensuring air exchange (free air circulation), must have additional properties, such as high wear resistance (for repeated washing and daily use), strength (to withstand contact with metal parts of the AFF) , suitability for sterilization (withstanding heat treatment), lightness. Transosseous osteosynthesis implies the presence of open soft tissue punctures, around the knitting needles and bone rods, bruising, biological discharge from the wound, the use of antiseptic ointments are possible, therefore, it is crucial that the material of the canvas has hygienic properties, repels moisture, and does not accumulate dust. The analogue material [2] does not possess the listed properties (except for free air circulation). The design of the cover should be such that the space inside the cover, after it is dressed on a limb, is tight, does not communicate directly with external air, for this the cover should fit snugly against the body, taking into account the shape of the limbs and the presence of parts of the AFF. The canvas for the cover [2] has the shape of a rectangle or such a shape when folded which forms a boot. This form is not always able to fit snugly to the body at the joints of the limbs, joining them to the body, for example in the groin, elbow, armpit, ankle. The cover [2] does not provide for armholes, curved cutouts that take into account the anatomical shape and the presence of parts of the AFF coming out from under the cover. The rectangular cloth from which the cover [2] is made in the form of a sleeve does not fit snugly on the limb, for example, when the cover is placed on the shoulder (in the armpit area) or the thigh (in the groin area), the edge of the cover is straight without cuts and is inconvenient for the patient for excessively overhanging fabric (canvas) or such a cover is not able to completely cover the AVF which can have a complex shape. A boot-shaped cover [2] contains a seam in the foot area, which causes discomfort, as the patient feels the seam, especially when there are injuries on the foot (for example, fistulas). At the same time, the presence of a seam is not hygienic, it complicates the sterilization of the cover, since the sheet is overlapped to remove dirt and biological discharge from the seam is much more difficult than from the rest of the sheet.

Thus, the covers [1; 2] do not provide full protection of the limbs and parts of the AVF from external influences, they do not allow the covers to be reused, washed and sterilized by heat treatment.

The technical result consists in ensuring the protection of the limb and mounted on it AVF, from the negative effects of the environment with a cover capable of repeated use and sterilization.

The technical result is achieved by the fact that the summer cover on the external fixation apparatus (hereinafter referred to as the cover) is made of a single-layer, one-piece soft flexible fabric that provides air exchange (air circulation through the fabric), contains a fixing tool for the closed sides of the fabric, made in the form of a zipper that allows you to hold the fabric in collapsed state, a tightening element made in the form of a cord passed into the channel along the edge of the web (braid), providing a tightening of the cover for its tight adjunction to the limb, The cord for the cord is formed by the fact that the fabric is bent and stitched along the edge. It differs in that the fabric is made of a fabric consisting of a mixture of cotton fibers and synthetic fibers with a content of the latter in the range from 20 to 80%, density in the range from 80 to 315 grams per square meter (g / m ² ), with water-repellent impregnation, strength tensile strength of at least 500 N, abrasion resistance of at least 3000 cycles, hygroscopicity in the range from 1 to 18% air permeability of at least 35 dm ³ / m ² sec.
