    SUSPENSION PREVENTION FOR PREVENTION OF PRESSURE Wounds
    FIELD OF THE INVENTION The invention relates to a seat reducer, the structure of which enables wheelchair users to prevent pressure ulcers in the buttocks.
    BACKGROUND OF THE INVENTION There are millions of disabled people in the world who need a wheelchair for their mobility. Prolonged sitting in a wheelchair or, for example, on an aircraft bench, always exposes the buttocks to pressure sores, and their healing requires a long bed rest or even surgery. Therefore, their effective prevention is really important for the quality of life of disabled people and the cost savings of healthcare. In Finland, the average cost of one pressure wound surgery for healthcare is 30,000 euros, and the treatment for the disabled person themselves causes a four-to-six-month ban on sitting. That is, prevent all movement during that time because the wheelchair cannot be used. In prevention, the core issue is that the compression of the upper body caused by the upper body can sometimes be removed and the blood O circulating in the muscles as freely as possible again. O 25 Intermittent depressurization is really important because in the sitting O position, the buttocks of the buttocks are exposed to as much as 80% = body weight. Traditionally, the pressure relief has been done with various seat cushion solutions and weight transfer and 3 relief instructions. According to the instructions, in the wheelchair 5, the occupant should lift the back off the platform every fifteen minutes for at least fifteen seconds and / or regularly tilt to the front and both sides. In addition, seat cushion manufacturers have a wide range of solutions to distribute the weight of the seat on the cushion as evenly as possible. The most effective way is to periodically move the bed to the side position, allowing the weight to be completely removed from the buttocks. Still, pressure sores occur continuously. There are many reasons: the unsuitability of human anatomy for prolonged sitting and the numbness and dysfunction of the gluteal muscles caused by paralysis, and the huge range of limitations caused by injuries. In some, his hands work in such a way that he is able to lighten his posture by lifting, but the hand forces of several are not enough for that and some of his hands are also completely paralyzed. In addition, wheelchair users are sometimes bothered by hurries and forgetting, especially if the buttocks area is numb and does not alert you to change position. In addition, it is not always possible to move to a lateral position.
    OBJECT OF THE INVENTION n The invention makes it possible to relieve the pressure on the buttocks with N detachable lighteners. It is suitable for the prevention of pressure ulcers of people of all levels and sizes> 25 with disabilities, including the weak and the completely paralyzed. The lightener can be installed in a wheelchair> like a wheelchair and even on an airplane or bus seat. E In this way, the pressure caused by prolonged sitting can be relieved S regularly and often enough. O 30 5
    SUMMARY OF THE INVENTION The core idea of the invention is a light and easy-to-operate lifter, with which the weight of the occupant can be completely removed from the buttocks on the armpits and thighs, if necessary. Lifting is done by means of padded supports that can be turned under the armpits and a lifting support under the thighs.
    The lighter is powered by a manually operated inflatable small mounting pad, several of which can be found in hardware store product lists. With the help of such a cushion, a lift of 7.5 cm is achieved, which is completely sufficient for relieving the pressure in the buttocks, and the cushion lifts a load of up to 250 kg. The sitter or his assistant uses the lift with a small hand pump. Alternatively, the lifting function can be implemented with an electric motor.
    The idea of the invention is based on a simple fact: If it is desired to prevent a pressure ulcer in the heel, then the foot is lifted off the base, whereby the pressure is released and the blood circulates again. It is not treated with various foam, air or gel pads placed under the heel, such as those used as seat bases in wheelchairs. The finest structure of the seat cushion does not eliminate the fact that its elasticity always ends at some point and the weight of the upper body can squeeze the buttocks again. Why not use the same technique to prevent a buttock pressure ulcer as with the heel S Of course, the buttocks would still be empty if the seat cushion were 2 25 rings, but then the weight of the upper body only stretches and tightens © the skin of the buttocks against the seat bones and also exposes it to pressure ulcers. z In the idea of the invention, the most important parts are the pivoting supports under the armpits 2 and the support part under the thighs, by means of which the seat S is lifted off the base on the armpits and thighs and the buttocks 5 30 remain in the air, completely without compression.
    Movable, lightweight and collapsible, it can even be placed under the seat on an airplane bench. Flights can take up to ten hours, during which time the person unable to walk must always sit still on a cramped bench where there is no room for light bending. And therefore the risk of getting a pressure ulcer in the buttocks is really high at that time. In addition, waiting times at airports can be really long, and the disabled person has little opportunity and space to move to a lying position. In this case, an easy-to-use lighter is really necessary. The lighter weighs about 4kg, is foldable and fits in a transport bag with a size of 40 x 40 cm and a thickness of 20 cm. The invention enables the disabled to participate in even long-lasting events, parties, festivals and travels without the constant fear of pressure sores and thus significantly improves the quality of life. Assistive devices for participation and mobility are always important and welcome for those wrestling with life-limiting injuries. The pressure wound reliever gives a whole new freedom. A person with a disability does not have to go to bed for months due to a pressure wound, and society has huge savings from reducing pressure wound treatments. OF O

    DETAILED DESCRIPTION OF THE INVENTION The principle of operation of the invention is summarized in Figures 10 and
    12. In Figure 10, a wheelchair user is sitting in a standard self-winding chair with a resting light mounted on it. In Figure 12, the lighter is mounted on the seat of the aircraft and has been raised to the lighter position by the user. The user's buttocks are now in the air and blood can circulate freely in them. Figures 1 and 2 show the structure and operating principle of the lighter. The user turns the padded armpit supports 1 under the armpits and pumps the air with the hand pump 2 via the hose 3 of the mounting pad 10, whereby the upper part of the lighter rises and the user with it. At the same time, the door 21 at the top of the seat of the lighter opens, whereby the user's weight is now focused on the armpits and thighs and the buttocks remain in the air. After about fifteen seconds of relief, the user opens the valve 23 of the hose 3, whereby the mounting pad 10 is emptied and the reducer lowers again to its rest position and the user can turn the armpit supports 1 away from under his armpits. Figure 1 clarifies the structure of the lighter. The lighter has adjustable vertical tubes 4, adjustable seat tubes 7 and 9 and adjustable leg tubes attached to the footboard 12. 11. This allows the lighter to be infinitely adjusted to the size of the user N 25 and the wheelchair. The stationary> standing lower part of the lighter and the rising upper part are fastened to each other = with lifting guides 8. Figure 2 shows how in the> lightening position the door 21 has opened and the rear part of the soft E seat cushion 7 has bent down at the same time. S 30 3 5
    In Fig. 3, the backrest tubes 4 of the lighter have been turned to the reclining position on the basis of the inclination adjustment 5. Figure 4 shows the structure of the lighter from behind. The adjustable rear support 15 supports vertical tubes 4 which can be bent forwards and backwards on hinges 14. Figure 5 shows the lower part of the lighter seat from above. The support plate 16 provides a lower support for the mounting pad 10. The guide knobs 18 of the door 21 guide the door back to its original position when the lighter is lowered to the rest position. The support tubes 17 are also adjustable, so that the width of the lighter can be changed. Figure 6 shows the top of the lighter seat from above. The support damper 19 provides an upper support for the mounting pad 10. In the relief position, the door 21 opens down on the hinges 20. Figure 7 shows a mounting pad 10 which is pumped by the pump 2 via the hose 3 and emptied by opening the valve 23. OF O OF
