Abstract

Usage: for medical equipment, in particular medical furniture. The medical bed contains a base 1, a bed 2, consisting of sections 4 located on the axis 3, through the openings of which preliminary stretched bundles are passed, fixed at their ends to the outer sections 4 and provided with a tension device 7. Each end section 4 is connected to an independent rotation drive 8 and a lift drive 11, the reversible electric motors of which are connected to a control unit, according to the program of which (or manual control) the sectional bed with the mattress 13 can perform the following movements: raising and lowering the patient; tilting the bed for inspection and other manipulations; tilting the bed with raising (lowering) the legs (head) of the patient to unload or stretch the spine; a helical motion of the bed for the study of joints and spine with regulation of the amplitude and frequency of oscillations; the same, with less frequency, to prevent pressure sores or to speed up falling asleep. 6 ill.

The invention relates to medical equipment, namely to beds for the prevention of bedsores in patients.

The purpose of the invention is to enhance functionality.

The goal is achieved in that in a medical bed containing a base, a section bed, one or more drives, according to the invention, the bed sections are located on the same axis and are interconnected by elastic elements, for example, pre-stretched rubber bands running parallel to the axis and through openings of sections, the axis being connected to the extreme sections via rotation drives and through rotary hinges to pushers of lifting drives, and the housing of one of the lifting drives is located on the base p. the possibility of horizontal movement along the axis.

Comparative analysis with the prototype shows; that the bed is characterized by the placement of bed sections on the same axis and interconnected by elastic elements. In this case, the axis is connected to the extreme sections via rotation drives and via rotary hinges to the pushers of the lift drives, and the housing of one of the lift drives is placed on the base with the possibility of horizontal movement along the axis.

Figure 1 presents a medical bed; figure 2 is the same, a top view; in Fig.3 - section aa in Fig.1; Fig. 4 is a diagram of a sectional bed, where the arrows show the movement made by its elements; Fig. 5 is a front view of a kinematic diagram of a medical bed and its drives; figure 6 is the same side view.

The medical bed consists of a base 1, a bed 2, made in the form of sections 4 placed on the axis 3, through the holes 5 of which parallel to the axis 3 pre-stretched rubber bands 6 are passed, fixed by their ends on the extreme sections 4. On one of the extreme sections 4 a device 7 for tensioning the harnesses 6 is installed. The extreme sections 4 are connected via axis 8 to the axis 3 and via rotary hinges 9-collisions 10 of the elevator 11. One of the hoist drives 11 is fixed on the base 1 rigidly, and the other with the possibility of horizontal movement along the axis 3. The electric motors of the drives 8, 11 are reversible and are electrically connected to the control unit 12. A mattress 13 is placed on the floor 2, for example, an anti-slip

Tigvo-puls T-81 / M36 cellular mattress with a pneumatic pulsator.

The bed works as follows. The control unit 12 according to a pre-configured program turns on and off the electric motors of the drives 8, 11, as a result of which the extreme sections 4 of the bed 2 make reciprocating movements in the vertical direction

0 and reciprocating movements relative to axis 3. In this case, the extreme sections 4 can move and rotate synchronously or in antiphase. In the latter case, bed 1 will make a wave-like motion, pressing a screw-like shape, as shown in Fig. 4. In addition, in block 12 provides manual control of the drives 8 and 11, with which you can carry out the lifting and rotation of the bed 2

0 at the request of the operator, patient or doctor. After turning off the electric motors, the drives 8 and 11 are self-locking, which ensures the fixation of the end position - bed 2.

5 The proposed medical bed may provide a number of functions arising from the possibility of changing the position of the sectional bed and then fixing it if necessary;

0 - raising and lowering the patient in a horizontal position with the position of the lifting drives;

- tilt of the bed (see Fig. 6) for inspection and other manipulations using 5 rotation and lifting drives;

- tilt of the bed (see Fig. 5) for unloading (stretching) the spine (includes one of the lift drives);

- helical motion of the bed (see

0 Fig. 4) (reverse-rotational movement of the rotation drives in antiphase - this movement allows you to work through the joints, develop the spine with the amplitude specified by the control unit);

5 - combined movement with a low speed of the lifting and turning engines;

a) combination-movement of the bed (see Fig.6) with the up-down movement of one of

0 lift drives (Fig. 5) - allows the application point of the resulting center of gravity of the patient’s body to vary over time and thereby prevent the formation of pressure sores. When tilting the bed with

5 drives of rotation, the patient does not completely turn on his side, however, the point of application of gravity is shifted towards the shoulder and he alternately lies on the left, then on the right side of the back, while if the legs are slightly higher than the head, then the point

the center of gravity is closer to the head, if the head is lower than the legs, then the center of gravity is shifted closer to the legs. If one oscillation period is performed for at least one minute, then the movement does not have a noticeable effect on the vestibular apparatus and even allows you to sleep during such manipulation with correctly selected oscillation amplitudes and promotes rapid falling asleep;

b) the combination of the spiral motion of the bed (see FIG. 4) with the up-down movement of one of the lift drives (FIG. 5) allows, in addition to preventing the formation of pressure sores, the development of the spine.

With accelerated operation of the engines according to the above scheme a or b and the use of a massage mat or a honeycomb mattress, you can massage the back and other parts of the body.

To increase the effectiveness of the anti-decubitus system, a cellular mattress can be fixed on the bed, for example, Tigvo-puls N-81 / M36 / 3 /, the design of which allows the pressure surface to be distributed throughout the body and to improve air circulation between the patient’s body and the mattress .

The proposed medical bed can be successfully used as a highly effective anti-decubitus system, as well as for stretching the spine, massage, as a hospital bed for developing the spine after injuries and operations. as a means to facilitate falling asleep and for other functions.
