Description

The invention relates to sports, general hygiene, medical field and can be used to accelerate recovery processes after heavy physical exertion, prolonged static postures, for example, in bedridden patients, for massage effects on various parts of the human body.

A known method of restoring the patient’s condition after physical exertion and prolonged static poses and a device for these purposes (brochure "Anti-decubitus system" AKS-decubiflow-100 ", Germany). The device contains a pneumatic air mattress with cells combined through one in two chambers, which, alternately, with the help of a compressor unit, pressure is supplied and relieved.

A method of restoring the patient’s condition after physical exertion and prolonged static poses involves redistributing pressure on the body of a lying person from the side of the mattress from pneumatic inflatable elements by periodically applying one or the other of two possible groups of inflated cells. At the same time, blood and lymph supply to tissues is facilitated, similarly to massage effects.

The disadvantage of the analogue is the limitation of functionality, since the method and device do not allow changing the position of a motionless lying person for care and impact on individual parts of the body.

Closest to the claimed is a method of restoring the patient’s condition after physical exertion and prolonged static poses and a device for its implementation (patent RU 2005452 "Method for controlling the process of anti-decubitus exposure to areas of the patient’s body and a device for preventing pressure sores" Cl. IPC ⁵ A 61 G 7 / 05, published on January 15, 94 Bulletin No. 1 and an advertising brochure for the device protected by this patent “Universal preventive and therapeutic device UP and LP-01“ Nadezhda ”manufactured by Skif, Voronezh, registration e license №95 / 311-319).

The method of restoring the patient’s condition after physical exertion and prolonged static postures according to the prototype includes periodically filling and releasing air pressure in two autonomous groups of pneumatically interconnected mattress elements. Moreover, first, both groups of mattress elements are filled with air, bringing it to a predetermined pressure value, then it is vented in the first group, maintaining at a predetermined level in the second group, then the first group of elements is filled and pressure is maintained in both groups at a preset value, then the pressure is relieved in the second group of elements, supporting it at a given value in the first group. In this case, the parts of the body that come into contact with the inflatable mattress elements under pressure are subjected to a vibration effect with a frequency of 15-25 Hz and an amplitude of not more than 0.55 mm.

The prototype device comprises a mattress consisting of a cover with cells and inflatable elements, united in groups. Each group is connected by a hose through a controlled valve to a control unit and a vibration compressor. When pressure is applied to one hose, another is depressurized and vice versa.

The disadvantage of the described method and device is the limitation of functionality, since it does not allow for massage movements associated with a change in body position, for example, alternating the lifting of the pelvic area with the lowering of the shoulder, and vice versa, or turning a person from side to side and others, which also facilitate patient care.

In addition, the described air mattress, even in a fully inflated state, easily bends and takes the form of a base lying under it, since it does not have sufficient bending stiffness, which does not allow aligning the body in a horizontal plane.

When creating this invention, the task was to develop a device that would increase the intensity of recovery processes after significant physical exertion, prolonged static postures, for example, in bedridden patients.

The task was to create a device that would be convenient for servicing patients and would have massage and static effects.

In solving this problem, the technical result is to expand the functionality of the device, as it allows a wide variety of massage and static effects on the person lying on the mattress.

The specified technical result is achieved in that, in comparison with a device for recovering a patient’s condition after physical exertion and prolonged static poses, comprising a compressor unit and a pneumatic air mattress consisting of a cover with cells and inflatable elements, the claimed device includes a new one - that inflatable elements combined into several zones symmetrically located relative to the longitudinal axis of the mattress, and in each zone the odd and even elements are combined into separate groups.

The compressor unit contains a switch that, by replacing the switching element, connects one or another group of inflatable elements to the compressor in accordance with the selected device operation scheme.

The upper and lower planes of the mattress cover are interconnected by additional jumper elements that form cells that resemble honeycombs. This design allows you to increase the rigidity of the mattress in the inflated state for better alignment of the lying person.

To simplify the manufacture and maintenance of the mattress, jumpers are attached only to the upper plane of the mattress cover, and the lower plane is formed by sections of jumpers connected to each other by means of Velcro.

Figure 1 presents the pneumatic diagram of the device; figure 2 is a section aa of figure 1; figure 3, 4, 5, 6, 7a, 7b are examples of the operation of the device.

The mattress contains a cover 1 of a honeycomb structure made of fabric and airtight inflatable elements 2 laid in a cell. Sealed inflatable elements 2 can be made in one piece with the mattress cover. The mattress is functionally divided into zones A, B, C, D, D, E, in each of which even and odd sealed elements are routed to their hoses 3 ... 14 connected to the outputs of the switch 15. To the input of the switch through hoses 16 and 17 connected to the compressor 18. The cells of the mattress cover are formed by the upper 19 (figure 2) and lower 20 planes connected by jumpers 21. The lower plane can be formed from parts of jumpers connected to each other by means of Velcro 22.

The device operates as follows.

The compressor 18 applies pressure to the switch 15 alternately through the hoses 16 and 17. The programmable switch 15 by replacing a switching element (not shown) in accordance with the desired scheme of the device, connects to the hoses 16 and 17 the selected sets of hoses 3 ... 14. So, if hoses 3, 4, 7, 8, 11, 12 are connected to the hose 16, and hoses 5, 6, 9, 10, 13, 14 are connected to the hose 17, then we obtain the operation scheme according to Fig. 5, when the pressure It is fed into zones A, B, D of the mattress and descends from zones B, D, E, and vice versa, with alternation, adjustable in time. The adjustment is provided by the control unit of the compressor unit.

To implement the operation of the circuit of Fig. 3, hoses 3, 5, 7, 9, 11, 13 are connected to the hose 16, and hoses 4, 6, 8, 10, 12, 14 are connected to the hose 17, while elements adjacent to the width of the mattress are inflated through one, the rest go down and vice versa. The scheme of operation in figure 4 is similar to the previous one, only with a shift of the right and left sides of the mattress by a step.

Implementation examples. Modes of operation according to the schemes of figures 3, 4, 5 can be carried out with a cyclical massage effect. The modes of operation according to the schemes of figures 3, 4 are similar to the modes of operation of many well-known mattresses and provide only a change in the contact points of the patient's body with the mattress. The operation mode according to the scheme of Fig. 5 provides a twisting effect when the shoulders and legs of one half of the body are raised, and the pelvis is of the other half and vice versa, while both a static position and a cyclic mode are possible. Work according to the scheme of Fig.6 by inflating one of the halves of the mattress allows you to turn a person on any side, for example, to change clothes or perform another procedure. The work according to the scheme of figa, 7b is used both for caring for bedridden patients, ensuring the inflation of one part of the mattress and the descent of the other for a long time, for example, to raise the pelvic area for embedding the vessel, and for massage or warm-up movements.

The pneumatic circuit of the device has 12 volumes, unlike most known devices having two volumes, and provides the multivariance of their connection to provide the required operating modes.

The increased rigidity of the mattress, and therefore its ability to even out the dips of the base lying under it, is determined by the fact that its upper and lower planes do not close anywhere, but are separated from each other by the height of the jumper. Inflatable elements, occupying the inflated state the entire cell volume, are in contact with each other by a plane, while the mattress is likened to a beam.

The presence of a programmable ability to choose which of the sealed elements to apply pressure to and from which to lower, as well as the large number of options for these sets allow a wide variety of massage and static effects on the person lying on the mattress.

The invention is applicable both in institutions for the care of bed patients, and at home, does not require special training of personnel.
