RU2231347C1 - Sanitary wheel litter - Google Patents

Abstract

FIELD: medical equipment, in particular, for manual transportation of patients from dwellings with staircases.

SUBSTANCE: litter has bed, tubular frame, drop back and three pairs of carrier wheels manufactured from plastic and made in the form of pulleys, three pulleys at each side of frame, said pulleys being covered with V-belt defining closed contour. Two brake devices are fixed at one end of frame. Each braking device has bracket, spring-loaded balance beam with brake shoe and flexible cable. Two tension members are fixed at other end of frame. Two pairs of arms with extensions are attached to both ends of frame.

EFFECT: improved operating characteristics, convenient use and reduced labor consumption owing to exerting of minimal physical force.

Description

The invention relates to medicine, in particular to medical equipment, is used primarily for the manual transportation of patients from residential premises with stairwells.

Known sanitary wheel stretcher containing a tubular frame, bed, handles and hinged legs pivotally mounted on the frame with wheels (see AS No. 1017328, A 61 G 1/02).

The disadvantage of this invention is that it is very overall both in assembled form and in the working position.

The complexity of the design will lead to an increase in the weight of the structure. Transporting by flights of stairs is very dangerous, without constant points of support.

Known sanitary stretcher - gurney. The stretcher contains longitudinal bars, each of which consists of two links connected by a swivel, and three pairs of wheels (see AS No. 2000092, C A 61 G 1/02).

The disadvantage of this invention is that the flights of stairs the patient must be carried on his hands, spending a lot of physical effort.

Known sanitary stretcher (see AS No. 249559, A 61 G 01/00).

The disadvantage of this device is that carrying patients requires large physical stresses.

This invention relates to trackless vehicles and can be used by people with disabilities to travel on stairs and along horizontal sections of the track.

The purpose of the invention is the improvement of operational characteristics and increase ease of use with the least use of physical labor.

Sanitary wheeled stretcher A.G. Dvoryanidova, having a tubular frame, a bed, a folding back, is characterized in that it has three pairs of support wheels made of plastic in the form of pulleys, wheels of three pieces on each side of the frame, fitted with a wedge-shaped belt forming a closed loop, on one ring to two braking devices are attached to the frame, consisting of an arm, a rocker arm, a flexible cable, two tensioning devices are attached to the frame at the other end, two pairs of handles with extensions are attached to the frame at both ends.

Figure 2 - lifting the stretcher on the flight of stairs by rolling.

Figure 3 is a support wheel in section.

Figure 4 is a section of the creek of the wheel and belt.

A sanitary wheeled stretcher consists of longitudinal pipes 1, which, together with transverse connections, form a stretcher frame 2, a hinged back 3 is hingedly attached to the top of the frame 2, allowing the patient to be transported in a half-sitting position. Two wheels 5, made of plastic, in the form of pulleys are attached to the frame 2 from two sides with clamps 4. The wheels 5, located in three pieces on each side of the frame 2, are covered with a V-belt 6, forming a closed loop. The height of the V-belt 6 is slightly higher than the depth of the creek of the wheel 5, so the outer wall of the belt 6 protrudes from the creek (figure 4) and bears all the load on itself. At one end, two braking devices 7 are attached to the frame, consisting of an arm 8, a spring-loaded rocker arm 9, and a brake shoe 10 attached to its lower end. A flexible cable 11 is attached to the other end of the rocker arm, which at the other end enters the extenders 12 of the handle 13. The cable exiting the extension cord in the vicinity of the handle 13 ends with a ring 14, which, when the stretcher descends from the stairs, the nurse puts on his index finger and as soon as the sanitary wheel stretcher begins to move down, the nurse pulls the flexible cable 11 over the ring 14 d, overcoming the resistance of the spiral spring (not shown) mounted with the beam 9, turns the beam 9 clockwise, the other end of the beam 9 together with the brake shoe 10, turning the same clockwise, presses the shoe 10 against the belt 19, part of which is on the end wheel pulley. Braking occurs and the stretcher is forced to slow down. At the end of braking, the orderly releases the ring 17, the coil spring rotates the beam counterclockwise and the shoe 10 moves away from the belt 19 and the braking ends.
