Description

The utility model relates to medical equipment, in particular, to devices for first aid by fixing the upper and / or lower extremities of people injured.

Immobilization as an integral part of first aid is used in the first hours and minutes after injury. Often, it plays a decisive role not only in the prevention of complications, but also in maintaining the lives of the wounded and injured. With the help of immobilization, peace is ensured, the interposition of vessels, nerves, soft tissues, the spread of wound infections and secondary bleeding are prevented. In addition, transport immobilization (immobilization for the duration of the patient’s delivery to the hospital) is an integral part of measures to prevent the development of traumatic shock in the wounded and injured. Timely and correctly performed transport immobilization is the most important first aid measure for gunshot, open and closed fractures, extensive soft tissue injuries, damage to joints, blood vessels and nerve trunks. The lack of immobilization during transportation can lead to the development of serious complications (traumatic shock, bleeding, etc.), and in some cases to the death of the victim.

The following requirements are imposed on modern tires for transport immobilization: the possibility of repeated use and use in any weather and climatic conditions, high rigidity in the working position, X-ray permeability, ventilation of the surface of the immobilized limb and access for visual control of its condition, as well as for the necessary manipulations.

These requirements are met by the folding medical transport immobilization tire with the cutaneous limb traction function, consisting of three or more elements, known from the patent for utility model RU 172400 U1 (A61F 5/05, A61F 5/01, published July 6, 2017). An element of the tire has a length of not less than the average anatomical length of the forearm in total with the length of the wrist of an adult, and the sum of the lengths of all elements in the extended position and with rigid bonding relative to each other exceeds the average statistical length of the lower limb of an adult by at least 20 cm. Each of the elements corner from two mutually perpendicular plates with bent edges, with through cuts in the planes of corners in the form of rectangles for ventilation and skipping of fixing straps s or straps and circular holes for fastening elements between a bracket and traction system limb. The individual corner elements of the tire have different sizes, selected so that all the elements can be inserted one into the other in the transport position and held relative to each other due to the bends of the guide edges of the corner plates. When bringing the tire into working position, the corner elements extend to the required length from each other and are fixed with through plastic latches or screws with wing nuts. If necessary, all elements of the tire can be used separately to immobilize different limbs. The tire elements can be spliced at right angles with the screws with wing nuts, plastic latches in combination with the fastening of the bus elements with tension belts or with an arm for the traction system. 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, including by passing fixing elements through the slots in the tire plates.

However, the known element of the tire has significant disadvantages. Bringing the tire into working position is a time-consuming process, as the individual elements of the tire must be fixed in several places using small fasteners that may be lost. In addition, the dimensions of the individual elements in the transport position do not ensure the compactness of the tire during storage.

These disadvantages are deprived of the busbar for transport immobilization, disclosed in patent RU 2367382 C1 (A61F 5/05, published September 20, 2009), assembled from small flat hollow elements inserted one into the other and fixed to each other on two sides by a lock connection of the protrusion type -hole. The number of assembled elements is determined by the required tire length. Separate elements of the tire have figured protrusions, figured holes and recesses for telescopic connection with each other along the length of the protrusions. The middle protrusion of one of the elements is inserted into the recess of the same profile of the other element, and two extreme identical curly protrusions form a locking connection by engaging the edges of the curly holes in the other element. Figured protrusions disengage from the figured holes due to the flexibility of applying to them a force directed perpendicular to the longitudinal axis of the element. Elements are made by stamping from polymeric or synthetic materials.

The objective of the utility model is to expand the arsenal of technical means designed to ensure transport immobilization of victims using a reusable busbar in all weather and climatic conditions, with high rigidity in the working position, low weight and compact dimensions in the transport position, X-ray permeability and ventilation of the immobilized surface limbs and access for visual control of her condition, as well as for the necessary mann of populations.

The technical result, the claimed utility model is aimed at, is to implement the indicated transport immobilization of the victims.

The claimed element of the busbar for transport immobilization is made flat and can be connected and fixed to each other on both sides by a locking connection. The tire element is made in the form of a structure of three interconnected plates, on the end sides of the middle of which there are figured protrusions and figured recesses designed to create complementary protrusions and cavities of the castle connection of the flat element. The middle plate on each end side has a figured protrusion and a figured recess.

The first shaped protrusion is made with a thickening at its lower end and with an undercut located under it. From the side of the thickening, a recess is made.

The first figured recess is a recess in the upper part of which, at a distance from the upper horizontal wall, there is an elongated protrusion with a head protruding from the vertical wall. A thickening is made on the face of the plate substantially opposite said elongated protrusion.

The second figured protrusion, located on the opposite end from the first figured recess, is made with a thickening at its upper end and with an undercut located above it. From the side of the thickening, a recess is made.

The second figured recess, located on the opposite end of the plate from the first figured protrusion, is a recess in the lower part of which there is an elongated protrusion with a head protruding from the vertical wall. A thickening is made on the face of the plate substantially opposite said elongated protrusion.

The dimensions of the figured protrusions and recesses and, accordingly, their thickenings and recesses correspond to each other and create complementary protrusions and cavities of the castle connection of the flat element.

When two solid plates are connected with a plate with a lock between them, an element is formed that has a protrusion and an opening on each end face for fixing with another similar element and forming a busbar.

The plates are made of a polymeric material, in particular polyurethane, and are interconnected with dichloroethane.

When connecting individual prefabricated elements to the tire, the second protrusion enters the first recess and is fixed in the recess due to the elasticity of the elongated protrusion. The thickening of the first figured recess, in turn, is included in the undercut of the second figured protrusion and is fixed in it. The first figured protrusion accordingly enters the second figured recess and is fixed by its thickening due to the elasticity of the elongated protrusion.

The essence of the utility model is illustrated by drawings, which show:

FIG. 1 - element of the busbar;

FIG. 2 - the middle plate of the tire element with curly protrusions and recesses.

Shown in FIG. 1 element 1 is intended for tire assembly for transport immobilization. Each element 1 consists of an upper plate 2, a middle plate 3 and a lower plate 4. As shown in FIG. 2, the middle plate 3 on each end side has a figured protrusion 6, 7 and a figured recess 5, 8.

The first figured recess 5 is a recess in the upper part of which, at a distance from the upper horizontal wall, there is an elongated protrusion 51 protruding from the vertical wall 51 with a head 52, and a thickening 53 is made on the end side of the plate 3 essentially opposite the elongated protrusion.

The first figured protrusion 6 is made with a thickening 61 at its lower end and an undercut 62 located below it, and a recess 63 is made from the side of the thickening 61.

The second figured recess 7 is located on the opposite end of the plate 3 from the first figured protrusion 6 and is a recess, in the lower part of which at the distance from the lower horizontal wall there is an elongated protrusion 71 protruding from the vertical wall 71 with a head 72, and on the end side of the plate is essentially opposite said elongated protrusion 71 made a thickening 73.

The second figured protrusion 8 is located on the end of the plate 3 opposite from the first figured recess 5 and is made with a thickening 81 at its upper end and an undercut 82 located above it, and a recess 83 is made on the side of the thickening.

The dimensions and arrangement of the figured recesses and protrusions correspond to each other and create complementary protrusions and cavities of the castle connection of the flat element 1.

When two elements are connected, the second figured protrusion 8 of the first element enters the first figured recess 5 of the second element, and the first figured protrusion 6 of the second element enters the second figured recess 7 of the first element so that the bulge 81 bends upward the head 52 and then slides along the elongated protrusion 51 , returning the head 52 to its original position, and the bulge 53 slides under the undercut 82 and then is located in the recess 83, thereby making the elements snap into place. Similarly, engagement is made between the first figured protrusion 6 of the second element and the second figured recess 7 of the first element.

Due to two corresponding curly grooves and protrusions, spontaneous separation of the elements is eliminated, and their longitudinal and transverse displacement is prevented.

Plates 2, 3, 4 of the elements are made of plastic polymer material, in particular polyurethane. It is advisable to use material in bright colors to attract attention. The thickness of the middle plate 3 is 4 mm, the thickness of the upper and lower plates 2, 4 is 2 mm. The plates are interconnected with dichloroethane. The protrusions and recesses on the plate are performed by laser cutting or stamping.

In the manufacture of the tire, the individual elements 1 are inserted into each other by direct translational movement of the elements to meet each other with the corresponding locking side until the locking device is fully latched. Upon reaching the required length, the tire is superimposed on the immobilized limb and fixed on it. Fixation of the tire on the limbs of the injured person is carried out with the help of a covering Velcro-type dressing bandage. If necessary, tires on an immobilized limb can be superimposed on both sides. When dismantling the bus elements 1 are disconnected.

It is possible to additionally equip the tire with an electronic device of the "timer" type, displaying the time elapsed since the tire was fixed on the limbs and the tourniquet was applied.
