Abstract

FIELD: medical engineering.

SUBSTANCE: device has flat bed on supporting members having backs. The flat bed is shaped as rounded rectangle with crosspieces and longitudinal sleepers. Bed back has irregular members for increasing rigidity. The crosspieces are made of straight metal tubes having not less than 0.5 mm thick wall and circular and/or non-circular cross-section and/or are bent on radius. The radius is not less than 1/8 times internal size of the smallest side of bed. The crosspieces bent on radius are turned with their convex surfaces oppositely to the backs or in concordance with orientation of the backs.

EFFECT: reduced structure weight; increased strength and comfort given to patients and nurses.

Description

The invention relates to medical equipment and can be used as a device for caring for patients, for example, as a hospital bed.

A bed for patients is known according to the description for the USSR author's certificate No. 49046, A 61 G 7/00, 08/31/1936, containing a bed with backs placed on supports, having the shape of an elongated rectangle with crossbars.

Known bed does not have longitudinal elements that ensure its rigidity and, therefore, is not a solid structure.

A closer analogue of our invention (prototype) can be considered a bed according to the description of the author's certificate of the USSR No. 111940, A 61 G 7/00, 08/01/1959, containing a bed with backs placed on supports, having the shape of an elongated rounded rectangle with cross-pieces and with longitudinal lags . The prototype has sufficient rigidity, but has a complex structure, as well as significant weight and cost, which excludes its widespread use in most medical institutions.

The problem solved by our invention is to create a simple and affordable medical bed with improved performance and comfort.

The technical result of the invention is manifested in reducing the weight of the structure, in increasing its strength characteristics, in convenience for medical personnel and patients.

The essence of the invention is expressed in the fact that the medical bed, containing a bed with backs placed on the supports, having the shape of an elongated rounded rectangle with cross-pieces and with longitudinal lags, unlike the closest analogue, has backs, which are equipped with curly elements for increasing stiffness and cross-section, made of straight metal pipes having a wall of at least 0.5 mm with a round and / or non-circular cross-section and / or bent along a radius of at least 1/8 of the inner dimension of the smallest side us bed, wherein the cross member, bent radially oriented convex surfaces of the opposite side of the backs or the side backrest orientation.

The above set of essential features is sufficient to achieve the technical result of the invention in all cases to which the requested amount of legal protection applies. In special cases of its implementation or use, the medical bed may contain at least two wheels, a bed with a spring-loaded net, having, for example, a rhombic cell or with a steel bar grill, or with a steel bar net, straight cross members covered by a laminated sheet of wood-fiber plates or a U-shaped profile of sheet steel with longitudinal stiffeners, backs made of pipes with round or non-circular cross-section, connected to the bed by corners and fixed with detachable or integral many joints, and backs, which are covered with a laminated wood-fiber board, while the bed may contain spring transverse strips made, for example, of plywood.

The causal relationship of the above features of the invention with its technical result is that the implementation of the backs of a medical bed with curly elements to increase rigidity gives significant weight savings (approximately two times compared with analogues), which also contributes to the implementation of cross-pieces from straight metal pipes with a wall of at least 0.5 mm and / or curved along a radius of at least 1/8 of the inner dimension of the smallest side of the bed.

The mentioned wall thickness of metal pipes along with rational selection of weight provides strength characteristics of all elements made of these pipes, and the above-mentioned bending radius of the cross members with the orientation of their convex surfaces to the opposite side from the backs characterizes patient comfort along with strength.

The lightness of the structure and its strength can be achieved at the lowest cost when making walls of round and / or square pipes connected to the bed by corners and secured with detachable and / or one-piece joints, as well as when performing backs closed with a laminated wood-fiber board.

Depending on the disease, the patient’s comfort is also facilitated by a spring-loaded net, for example, with a rhombic cell or a steel bar grill or a steel bar grid and straight cross members, which are covered by a laminated wood-fiber board or a U-shaped profile made of sheet steel with longitudinal stiffeners.

The invention is illustrated in the drawing, where Fig.1-6 depicts a medical bed in various versions of its implementation.

Medical bed contains placed on the supports 1 bed 2 with backs 3.

Bed 2 has the shape of an elongated rounded rectangle with crossbars 4 and with longitudinal lags 5.

The backrests 3 are provided with figured elements 6 for increasing stiffness, and the cross members 4 are made of straight metal pipes with a round and / or non-circular cross section and with a wall of at least 0.5 mm and / or curved in a radius of at least 1/8 of the inner size of the smallest side of the bed 2, and the radius-curved cross-beams 4 are oriented by convex surfaces in the opposite direction from the back (see FIG. 2) to the orientation of the backs 3 (see FIG. 5). A medical bed may contain at least two wheels 7, a bed 2 with a spring-loaded mesh 8, for example, with a rhombic cell or a grid 9 from a steel bar or a grid from a steel bar. The straight cross members 4 can be covered with a laminated wood-fiber board 10 or a U-shaped profile 11 made of sheet steel with longitudinal stiffeners. The backrests 3 can be made of pipes with a large or small (square) cross-section, connected to the bed by corners 12 and secured with detachable or integral joints.

The backs 3 can be covered with a laminated wood-fiber board, and the bed 2 can contain spring transverse strips 13 made, for example, of plywood.

When operating the bed, it is installed in the right place, lifting one of the backs 3 and using the wheels 7. Moreover, the figured elements 6 together with the cross members 4, longitudinal lags 5 and corners 12 exclude deformation of both the backrest 3 and bed 2. Since this bed has weight, approximately half that of standard medical beds, this operation can be performed by one person, moreover, not only within the same room.

Then, after appropriate preparation, the patient lies on the bed, to whom, for example, a spring-loaded mesh 8 with a rhombic cell or springy transverse strips 13 provide the necessary comfort.

The corresponding bending of the cross member 4 does not prevent the deflection of the spring-loaded mesh 8, but provides the necessary structural rigidity.
