Description

Functional bed.

The invention relates to the field of medicine, namely to the equipment of medical institutions, in particular to multi-purpose hospital beds

Known traumatic bed for traumatic No. 891092, M. Cl. C A61G7 / 08. onubl. 12/25/81, containing a bed of two frames, backs, height-adjustable legs with wheels. Between the back and the upper frame of the bed there is a screw mechanism for adjusting the inclination and fixing of the frames, made in the form of a coupling and two rods with left and right threads.

The disadvantage of this design is the small functional capabilities of the bed.

The closest technical solution is the Functional bed, item Russia No. 1412782, MNC 6 A61G7 / 00, publ. 01.20.95, taken as a prototype

The functional bed contains a base on wheels made in the form of a leaf spring connected to the frame (bed) by means of an arm and an axis, a three-section panel mounted on the frame, a back section tilt drive, a foot section tilt drive, a frame tilt drive made in the form of a screw with two nuts with right and left thread. The drive controls are made in the form of handles placed on different sides of the bed.

The disadvantage of the prototype is the inability to adjust the frame in a vertical plane and inconvenience in its operation.

The objective of the proposed technical solution is to expand the functionality of the bed and facilitate its operation.

.

This problem is solved due to the fact that the bed contains a base on wheels, an interconnected frame with a three-section panel, the tilt sections of the panel sections, a drive for changing the position of the frame with a screw mechanism, drive controls with handles, according to the invention, the base is made in the form of crossbars equipped with guide racks for installing the frame with the possibility of its vertical movement, the drive for changing the position of the frame is made in the form of a pivot-lever mechanism, the levers of which are connected with the frame, the base legs and the thrust interacting with the screw mechanism and the governing body, and the handles of the actuator controls are placed on the end face of the foot section in the same plane ..

The drive controls are made in the form of bushings pivotally connected to the handles and provided along the axis with a conical groove made at an angle.

The angle of the groove cone is 5-7 °

The sleeve is made of resilient plastic.

The implementation of the bed base in the form of crossbars equipped with guide racks for installing the frame, and the interaction of the frame and guide racks of the base with the levers of the articulated-lever mechanism for changing its position, connected through a rod with a screw mechanism and a control element, provide vertical movement of the frame, which extends the functional bed options. Placing the handles of the controls on one side, on the front side of the foot section, in one plane provides convenient operation of the bed.

The presence of elastic bushings in the drive controls pivotally connected to the handles and provided along the axis with a conical groove made at an angle ensures a change in their position in space and fixation of the occupied

provisions. Handles can be folded and tucked under the bed, which also allows convenient use of the bed.

The conducted patent studies suggest that the claimed technical solution has novelty.

The proposed device is industrially applicable existing technical means.

Thus, the proposed technical solution meets the established criteria of the utility model.

The essence of the claimed technical solution is illustrated by drawings, where in FIG. 1 shows a general view of a bed (without a three-section panel) with a drive for changing the position of the frame (its vertical movement), FIG. 2 - tilt drive of the back section, in FIG. 3 - tilt drive of the hip and foot sections, in FIG. 4 is a view A in FIG. 1, FIG. 5 - assembly B in FIG. 2, in FIG. 6 is a view E of FIG. 1, in FIG. 7 is a section BB in FIG. 6, section GG in FIG. 5.

The functional bed contains a base 1 on wheels 2, a frame 3 with a three-section panel 4 (back section 5, hip 6 and foot 7), tilt section drives, respectively, 8, 9, and a drive for changing the position of the frame 10 (vertical movement) with a screw the mechanism 11, as well as the controls of the actuators 12 with handles 13.

The base 1 is made in the form of beams, at the ends of which the guide rails 14, for example, box-shaped sections, are rigidly fixed. The wheels 2 mounted on the base are self-aligning with brakes 15.

Frame 1 - metal, quadrangular welded construction from bent profiles. Guides 16, for example, of a box-shaped profile, are rigidly mounted in the corners for installation in guiding racks 14. Under the frame 3 from the side

the transverse element 1 7 is rigidly fixed to the foot section, to which the brackets 18 are attached with brackets 19 in which plastic bushings 20 are installed for accommodating the non-threaded parts of the screws 11 of the drive mechanisms. The bushings 20 are secured against rotation by the bolts 21. The pins 22 prevent the axial movement of the screw 11 of the drives. In the center of the longitudinal elements of the frame 3, on both sides, brackets 23 are mounted for articulation with the dorsal 5 and hip 6 sections. On the side of the foot section on the frame 3, a bar 24 is pivotally mounted for articulating with the foot section 7. Backs 25 are rigidly fixed to the frame 3.

The sections of the three-section panel 4 are made of a bent profile. The supporting elements of the 26 sections are made in the form of bent metal profiles rigidly and sequentially installed one after another.

The tilt drives of the dorsal 5 and hip 6 with the foot 7 sections are made in the form of screws 10, interacting with the corresponding rods 27 and 28. The rods are tubular, provided with threaded bushings (nuts) 29 at the ends, welded into them., To ensure axial movement of the rods. The rods 27 and 28 are pivotally connected to the levers 30 and 31 to interact with the respective sections.

The drive for changing the position of the frame 3 (vertical movement) is made in the form of a pivot-lever mechanism, the two shoulders of which 32 and 33 are pivotally connected to the frame 3, guide racks 14 of the base 1 and rods 34 and 35 interacting with the screw 11 and the control 12c with the handle thirteen.

The handles of the drive controls are located on the end face of the foot section in the same plane. The controls of the actuators are made in the form of bushings 36 pivotally connected to the handles. The bushings are made of resilient plastic, such as ABC. The conical groove 37 is made along the axis of the sleeve at an angle of 15-17 °.

The angle of the groove cone is 5-7 °

The operation of the bed is as follows.

To change the position of the patient, the slope of the corresponding section — the dorsal 5 or the hip 6 with the foot 7 — is changed by rotating the handle of the corresponding drive control. In this case, the screw 11, fixed from axial displacement, provides translational movement of the corresponding thrust, which, through the system of the corresponding rods, changes the slope of the corresponding section. In a specific implementation example, the left handle (from the leg section) is used to tilt the back section, the right handle is to tilt the hip and foot sections, the central handle is to vertically move the bed with the sections. This provides a wide range of different patient positions - within 30 °, and the vertical movement of the bed - within 180 mm

By changing the position of the handle relative to the conical groove made at an angle to the axis of the sleeve 36, the handle can be folded and put under the bed.

Thanks to the high-quality coating of metal parts and galvanized fasteners, the bed is reliably protected from corrosion and can maintain multiple disinfection.
