Description

Anti-bedsore inflatable cushion

Technical Field

The utility model relates to a cushion especially relates to a prevent bedsore inflatable cushion.

Background

At present, more and more people are in a sitting posture state for a long time in daily work and life, especially the disabled with inconvenient actions and office groups. No matter people sitting in an office for a long time or the disabled needing to ride instead of walk by virtue of a wheelchair, when the disabled is in a sitting posture state for a long time, a cushion is placed on the office chair or the wheelchair and used for adjusting a contact point between the hip and the seat so as to relieve the fatigue of the hip. However, a general seat cushion has a large contact area with the buttocks of the user, and when the user sits down, the seat cushion is completely in contact with the buttocks of the user, and most surfaces of the buttocks are in a pressed state, so that air circulation around the contact surface between the buttocks and the seat cushion is poor, discomfort is easily caused at the sitting position support point of the buttocks, and a severe person may cause a bedsore.

Disclosure of Invention

The utility model aims to solve the problem that a prevent bedsore inflatable cushion is provided, this kind of prevent bedsore inflatable cushion can make to have the clearance between user's buttock and the cushion, ensures the circulation of air between user's buttock and the cushion, improves user's comfort level, prevents that the user from leading to bedsore because of sitting for a long time. The technical scheme is as follows:

an anti-bedsore inflatable cushion comprises a base layer, a surface layer and an inflatable head, wherein the surface layer covers the base layer; the surface layer is provided with a plurality of air bags and a plurality of air passages, the air bags are formed by first convex parts protruding upwards from the surface layer, and the air passages are formed by second convex parts protruding upwards from the surface layer; the air bags are uniformly arranged into a plurality of rows and a plurality of columns, gaps are reserved among the air bags, the air passage is communicated with each air bag, and the inflation head is arranged on the surface layer and communicated with the air passage; the method is characterized in that: each air bag is provided with a plurality of convex ribs, and a valley part which is concave inwards is formed between every two adjacent convex ribs.

The first convex part forming the air bag and the second convex part forming the air passage are both formed by the surface layer through plastic suction or injection molding, and the part of the surface layer outside the air bag and the air passage can be closely covered and connected with the base layer in various ways, such as heat sealing or (through adhesive) adhesion.

After the air bags are inflated through the inflation head, the air bags which are compactly arranged are used as supporting points of the cushion, when a user sits, the convex ribs on the air bags are in contact with the buttocks of the user, and gaps among the air bags and valley parts among the convex ribs form air flow channels together, so that air can smoothly circulate between the buttocks of the user and the cushion when the user sits down, stuffiness and heat caused by long-time sitting of the buttocks of the user are eliminated, the comfort level of the user is improved, and bedsore caused by long-time sitting of the user is prevented.

As the utility model discloses a preferred scheme is in on the same gasbag many beads, every bead outwards and downwardly extending to the bottom edge of gasbag from the top of place gasbag, many beads on every gasbag are evenly arranged. The apex of gasbag is as the starting point of all beads on the gasbag, and the gasbag is sunken downwards when the user sits on the cushion, and the apex of gasbag is as the strong point between user's buttock and the cushion, and the supporting role to user's buttock is further assisted to many beads of evenly arranging on the gasbag moreover, and the pressure that every bead bore is equalling, makes that the user sits more comfortable.

For optimizing the air flue setting of inflatable cushion, as the utility model discloses further preferred scheme all there is an at least bead on each gasbag, and the bottom of this bead is linked together with the bottom of one of them bead on another adjacent gasbag. Two adjacent gasbags all carry out the circulation of air through two beads that the bottom is linked together, can make the gasbag set up compacter for whole inflatable cushion can only reserve an air flue of connecting the inflation head.

As a further preferable scheme of the present invention, the surface layer and the base layer are divided into a plurality of inflation regions by a plurality of heat-sealing lines, a plurality of air bags are uniformly distributed in each inflation region, and two air bags in different inflation regions are relatively independent; and each inflation area is provided with one inflation head. The cushion is divided into a plurality of inflation areas, each inflation area is provided with an independent inflation head for inflation, and the situation that the use of the whole cushion is influenced due to the fact that one air bag in one inflation area is damaged and leaks air is avoided.

Compared with the prior art, the utility model, have following advantage:

the utility model discloses prevent bedsore inflatable cushion has set up many beads in the gasbag of superficial layer, and form inside recessed trough of valley between two adjacent beads, aerify the back to the gasbag through inflating the head, arrange a plurality of gasbags of compactness as the strong point of cushion, when the user sits, bead on the gasbag contacts with user's buttock, and clearance between the gasbag and trough of valley between the bead form the air flow channel jointly, it is smooth and easy to make the user air can circulate between user's buttock and cushion when sitting, eliminate the vexed hot sense that user's buttock produced because of sitting for a long time, improve user's comfort level, prevent that the user from leading to bedsore because of sitting for a long time.
