Description

Combined bedsore-proof gel ventilating pressure-reducing cushion

Technical Field

The utility model relates to the field of cushions, in particular to a combined bedsore-proof gel breathable pressure-reduction cushion.

Background

Modern people have a short working rhythm, and many working sitting postures need to be more than 8 hours. The wheelchair is suitable for long-term patients and the elderly who need to sit on the wheelchair. Because the blood circulation of human buttock is bad, the temperature is increased, the humidity is increased, the local shearing force and the friction force are increased due to sedentariness, the bedsore problem is easily caused, the health of the human body is influenced, and the social medical burden is increased. And use the pressure that anti-bedsore cushion then can directly reduce skin tissue and receive, increase buttock blood oxygen content, reduce temperature and humidity to avoid blood circulation problem and bedsore problem.

Therefore, the design of the bedsore-proof cushion mainly takes the reduction of the stress borne by the buttocks by various methods as the main attack direction. In order to reduce the local friction force, pressure and shearing force of the buttocks of a human body, various flexible deformable materials are used for solving the deformation pressure generated by the sitting posture of the human body. The main bedsore-preventing cushion in the current market is: latex gaskets, sponge gaskets, inflatable cushions, gel cushions, water bag cushions and polyurethane foam cushions. The excessive air quantity of the inflatable cushion is not as good as increasing the pressure of the ischiadic tuberosity protrusion part, and the insufficient inflation of the inflatable cushion also cannot play the roles of supporting and dispersing the pressure and lacks enough elasticity. Latex, sponge and foam cotton, which have certain elasticity but need extremely thick materials to manufacture the cushion, and more than 500 micropores per cubic centimeter are easy to accumulate heat and accumulate bacteria, human body dander and fine garbage, and are difficult to clean. Latex, sponge and foam cotton cushions generally have elasticity in a given shape and cannot deform adaptively according to different human buttocks and ischial bony prominences. The full-gel water bag cushion has the functions of cooling and radiating, cannot completely wrap, loses elasticity and cannot deal with other shearing force and friction force except the vertical pressure direction.

The cushion of single material can't both satisfy high elasticity, cooling, dampproofing, antibiotic, high wrappage nature, and the air flows, reduces the numerous requirements of frictional force and shearing force to can not rely on the cushion of single material to reach the effect of prevention bedsore. The polyurethane foam cotton has high elasticity, smooth surface, closed pores, good biocompatibility and excellent natural degradability, but can accumulate heat and seal water after reaching a certain thickness, and sweat can be secreted after the skin temperature rises, so that the humidity is increased, and the hip is not favorable for dryness and comfort.

The cushion with the air blowing function blows air to the buttocks directly due to the air blowing channel, and blows bacteria and peculiar smell of a sedentary or sick patient on the cushion to the periphery of the air, so that the cushion is very insanitary and unsafe.
