Description

The utility model relates to medicine, namely to disaster medicine, military medicine, surgery, traumatology, medical equipment, specifically to medical transport tires for immobilization of limbs and anatomical segments of the body in case of damage and to the methods of using such tires.

A known analogue (compact transport bus) in the description of the patent application RU 2003113253/14, A61F 5/00, publ. November 10, 2004, which is a jaw consisting of flexible material with rigid sections attached to it, located at a certain distance from one another, due to which the elements can be nested into each other, forming a rigid single tire structure of the required length, fixed to the limb using a flexible material.

Disadvantages: the design of the compact transport tire does not allow the tire to be molded according to the required anatomical shape, it does not allow the tires to spliced in width or at an angle to each other. The lack of perforation in the tire does not allow the immobilized limb to be ventilated, which can lead to maceration of the skin surface from moisture or body fluids.

Known analogue (tire for transport immobilization) in the description of the invention to patent RU 2367382, A61F 5/05, publ. 09/20/2009, which is a set of flat elements partially inserted into one another with fixation by an elastic locking joint.

Disadvantages: the design of the compact transport tire does not allow the tire to be molded according to the required anatomical shape, it does not allow the tires to spliced in width or at an angle to each other. The flat design of the tire provides rigidity in only one plane, with the possibility of bending the tire in another plane. The rigid construction of the tire does not allow for bending. The lack of perforation in the tire does not allow the immobilized limb to be ventilated, which can lead to maceration of the skin surface from moisture or body fluids.

A known analogue (medical transport folding tire Petrushin-Shutak) in the description of the invention to patent RU 2367382, A61F5 / 05, publ. 10.27.1999, which is two groups of pivotally connected rigid flat sections with hinged side sections that can be folded into a rigid spatial structure of two parts located at right angles to each other, fixed by stoppers.

Disadvantages: non-universal design - the ability to use only on certain departments of the limbs, the lack of anatomical adaptation of the tire, insufficient fixation of the limbs when their diameter is much smaller than the width of the tire.

The analogue is known (a tire for the transport immobilization of a person injured in emergencies and traffic accidents) in the description of the invention to patent RU 2150918, A61F 5/01, publ. 06/20/2000, which is a set of telescopically extendable and fixed reinforced box-shaped elements of a rectangular open profile inserted into one another, which can be bent along the notches into a given profile.

Disadvantages: insufficient lateral fixation of the limbs when their diameter is significantly less than the width of the tire box. The lack of perforation in the tire does not allow the immobilized limb to be ventilated, which can lead to maceration of the skin surface from moisture or body fluids.

A known analogue (disposable molding medical transport bus) in the description of the invention to patent CN 204671349 (U) publ. 19/30/2015, which is a multilayer strip consisting of an upper protective layer, a reinforcing mesh, a layer of superabsorbent polymer and a ventilated lining layer. The multilayer molding tire allows you to give it any desired anatomical shape and fix it by wetting the superabsorbent polymer layer with water, as a result of which the polymer becomes rigid and retains its shape.

Disadvantages: irreversible polymerization of the superabsorbent layer does not allow reuse of the tire or correction of its overlap. There is no possibility of splice tires along the length or width.

The closest analogue is known - the prototype (universal molding reusable medical immobilization tire) in the description of the invention in patent US 6981956, publ. January 3, 2006, made in the form of a wide tape made of foil made of plastic alloy, which is plastic deformable by application of the force of the fingers of the hands and is made of an aluminum alloy foil laminated on both sides with a foamed elastic polymer material. When applying a tire to a deformable laminated aluminum tape, any desired shape can be imparted, including creating a spatial profile (T-shaped, V-shaped, U-shaped and U-shaped with bends of the edges) to give the tire rigidity. A molding tire superimposed on a limb is secured with bandages or any kind of fixed ties. If necessary, the tire can be trimmed with scissors to create small tires (for example, to fix the bones of the fingers).

Disadvantages: there is no possibility of splice tires along the length, width or at an angle. The lack of perforation in the tire does not allow the immobilized limb to be ventilated, which can lead to maceration of the skin surface from moisture or body fluids.

The utility model is based on the task of creating a compact transformable universal reusable molding transport immobilization medical tire with the ability to quickly form an anatomically conditioned configuration and tire profile using the strength of the hands, the ability to splicing individual tires along the length, width and angle to create spatial structures (including the number of evacuation stretchers and other evacuation devices), with good spatial rigidity in the working position, having a structure that provides ventilation of the surface of the immobilized limb, applicable in any weather and climatic conditions, light, taking up little space in the transport position, having X-ray permeability.

The solution to this problem is provided by the fact that in a perforated molding medical tire for temporary transport immobilization of damaged limbs or body segments, containing in its construction a plastic and reversibly deformable aluminum alloy tape laminated on both sides with foamed polymeric material, all three layers of the tire strip are made with through perforation with a hole size sufficient for threading through them a cord or plastic snap locks, and provided with the possibility of fixed on a layer of tape facing the body of an additional removable non-woven layer of disposable material, fixed on Velcro fasteners.

The inventive molding transport immobilization medical tire is made of aluminum alloy hand tape with a thickness that allows it to deform plastically using only the strength of the fingers, while remaining permeable to x-rays. The size of the tape can be any, due to the appropriateness of use in certain age and gender groups of patients. For example, a universal tire can have a length of 100 cm and a width of 14 cm. At the same time, on both sides the tape of a deformable aluminum alloy is laminated (by heat, adhesive or a combination thereof) with foamed polymeric material, for example, foamed polyethylene, which ensures ease of use of the tire, protects soft tissue immobilized limbs from damage (including thermal or cold), allows the processing and disinfection of the tire for reuse. At the same time, through the layers of the tire, even through holes with a diameter sufficient to thread the connecting cord or plastic spring-loaded snap fasteners are evenly distributed across the entire tire surface through all layers.

The distance between the holes is chosen sufficient to maintain the mechanical strength and stiffness of the tire and to ensure ventilation of the surface of the immobilized limb.

Due to the ability of the aluminum alloy layer to deform plastically when applying the force of the fingers and maintain the attached shape and position, the claimed tire can be stored in the transport position in the form of a compact roll or in the form of a stack of equal length folded stacks with excesses of tape. From the transport position, the tire is easily straightened and used fully in length or folded several times until the desired length is reached. Also, the tire can fit a limb on both sides or completely wrap around a fixed element, for example in the form of a fixing collar when applied to the neck. If it is necessary to extend the tire, increase its width, length, create a spatial structure or evacuation devices, individual tires can be spliced together in length, width or at an angle using a cord or plastic snap fasteners threaded through combined through holes in the tires.

To impart spatial rigidity, eliminating or reducing the possibility of changing the longitudinal curvature of the tire, it can be given a T-shaped, V-shaped, U-shaped and U-shaped with curved edges in cross section. If it is necessary to obtain individual curly or small parts for immobilization, the claimed tire can be cut into elements of any shape using steel scissors for cutting clothes.

The tire can be fixed on immobilized limbs and body parts using lingering belts, fabric strips with Velcro locks, cords, adhesive tape, regular or elastic bandages, strips of torn clothing or fabric, and any other improvised materials.

The design of the tire and the properties of the materials used allow the tire to be used repeatedly, cleaning and disinfecting if necessary. The absence of elements in the tire structure whose properties change upon wetting, contamination, cooling or heating within the temperature ranges known in all climatic zones of the world, allows the design to be used for its intended purpose in almost all environmental conditions.

The utility model is illustrated in FIG. 1-5. In FIG. 1 shows a side view and a top view of a molding transport immobilization medical tire and samples of means for fixing it on a limb or body part. In FIG. Figure 2 shows the transport position of the molding immobilization medical tire. In FIG. 3 shows options for lateral profiling of a tire to give it longitudinal spatial stiffness. In FIG. Figure 4 shows the options for splicing tires along the width and length using cords or plastic snap elements. In FIG. Figure 5 shows some options for applying the tire with fixation on the limbs with fabric tapes with Velcro fasteners.

As shown in FIG. 1, the molding transport immobilization medical bus is a tape of three layers of materials joined together (FIG. 1B: a layer of foamed polymer material - 1, a layer of deformable aluminum alloy - 2, a layer of foamed polymer material on the back side - 3 ) having through perforation (Fig. 1A - 2 and Fig. 1B - 2). Fixation of the tire on the limbs can be carried out by any fixing means, for example, tightening belts with a spring lock (Fig. 1A - 4), fabric strips with Velcro fasteners (Fig. 1A - 5) or ordinary or elastic bandages (Fig. 1A - 6).

The utility model works as follows. From the transport position (Fig. 2A or B), the tire is straightened by hands to the state of a straight and flat tape. Depending on the place of application of the tire, the multilayer tape is given the required length by unscrewing the excess length of the tire or splicing several tires into a single unit (Fig. 4B) using perforated ribbons of the tire cords (Fig. 4-7) or plastic snap fasteners ( Fig. 4-8). Tires can also be spliced together in width to create immobilization means for pelvic fractures or other injuries requiring a large immobilization area or when creating an evacuation stretcher (Fig. 4A). Tires can be spliced together at different angles, for example, to immobilize bone fractures of the upper extremities (Fig. 5 - III).

To give the tire longitudinal rigidity, it can be profiled with your hands in the transverse direction. Depending on the place of application of the tire to give longitudinal stiffness, transverse T-shaped profiling can be given to it (Fig. 3 - D), which is also used to give rigidity to evacuation stretchers from tires; U-shaped transverse profiling (Fig. 3 - A) and V-shaped transverse profiling (Fig. 3 - B) are used in most cases of limb immobilization. With a significant length of the tire, its U-shaped profile can be enhanced by additional bending of the edges of the tape (Fig. 3 - B). The tire can be applied depending on the immobilized element on one side of the limb (Fig. 5 - III), on both sides of the limb (Fig. 5 - I, II) or wrapped around a fixed element (Fig. 5 - IV). The superimposed tire is fixed by means of tightening belts with a spring lock (Fig. 1A - 4), fabric tapes with Velcro fasteners (Fig. 1A - 5), regular or elastic bandages (Fig. 1A - 6), cords threaded through through holes either using strips of cloth or any other improvised materials.

When studying other well-known technical solutions in this field, the differences that exist in the proposed device were not revealed in such a combination of structural elements and their connections, allowing to create the possibility of splicing individual tires along the length, width or at an angle to each other, simultaneously with the molding of tires anatomical contours while maintaining ventilation of the surface of the immobilized limbs through the through perforation of the tires.

The advantage and difference of the claimed utility model of a molding transport immobilization medical tire over analogues is:

- the presence in the tire structure of a plastically deformable layer of aluminum alloy, which allows the tire to be reversibly molded along the anatomical contours with the creation of a curly cross-shaped profile to give the tire longitudinal spatial stiffness, with the possibility of reusable use.

- the presence in the tire structure of through perforation that allows you to ventilate the surface of the immobilized limb or part of the body, and used to spliced tires along the length, width or at an angle to create spatial structures for immobilization or evacuation, used to fix the tire in the required position and the ratio of the parts of the tire with using a cord threaded through openings of through perforation.
