Abstract

The utility model discloses improved air pads with multiple air chambers in multiple sets. Communicating passages between chambers outside the chambers and on a pair of edges vertical to the chambers are made into superposed multipath flat communicating passages clamped between pad bodies and an upper layer film like a multilayer printed circuit board. The air pads with no spiral added thick edges are convenient for folding package, storage and transportation, use and maintenance and are favorable for production. The air pads can also be matched with an air source controller, guiding pipes and other parts in the patent application No. 91232959. The air heating pads can be used as air pads on beds for preventing and treating bedsores and can be conveniently used as refreshing health air pads on various deck chairs and chairs.

Description

Improved pneumatic mattress with many inflatable chambers

This utility model belongs to bedsore prevention and treatment and health care apparatus.

The inventor's patent application: 91232959, though can implement, when manufacturing air cushion,, need the pad material of double spread for manufacturing communication passage between the chamber on the air cushion because of be coated with the rubber and plastic fabric in utilization, this is a difficulty to part producer.

The purpose of this utility model is that the structure of specially organizing communication passage between pancake chamber on the air cushion at multicell is further improved more, make under the conditional situation of raw material, can use the pad material of single spreading, and utilize communication passage between mode structure chamber, lower floor limit needn't be in aforementioned patent applications.

Scheme provided by the utility model is applicable to that the chamber group counts n greater than 2, with being coated with rubber and plastic fabric, rubber plastic film or other gastight thin mold materialss, and the air cushion of making through bonding, hot pressing or sewing tech.With manufacturing air cushion main body (pad and upper strata mould) or/and manufacture the thin-film material of its chamber (surrounding edge), with with make the same technology of chamber, in the chamber outside with the perpendicular a pair of air cushion edge of chamber, be made into as the multilayer printed circuit board be clipped between pad and the upper layer film, stacked multichannel pancake communication passage up and down.Each road pancake communication passage is communicated with each chamber in one group of chamber, and has an air inlet/outlet that leads to outside the pad.Each road pancake communication passage is then not exchanged information or is leaked gas.The pancake communication passage is communicated with each self-corresponding chamber, can use the fusiformis valve nozzle that uses in the common air cushion, also can use with communication passage itself with spline structure but short pancake is communicated with pore.

Multichannel pancake communication passage is clipped between pad and the upper strata mould, and is stacked up and down and air tight mutually, and this is to implement key of the present utility model.For this reason, a kind of scheme is that each road pancake communication passage all constitutes with surrounding edge as chamber, separates but must or be coated with the rubber and plastic fabric with gastight rubber-plastics material between the stacked mutually pancake communication passage.Second kind of scheme is that each road communication passage is all used softish gastight rubber-plastics material or is coated with the pancake pipeline formation that the rubber and plastic fabric is made.The third scheme is, the communication passage of using surrounding edge to constitute is stacked with the communication passage space of pancake pipeline formation, and at this moment gastight pancake pipeline had both played buffer action, again as one of communication passage.

Penetrating a stranded cotton rope or other in each group pancake communication passage can interstitial substitute, causes the communication passage obturation in the time of can preventing the air cushion warpage.

Organize air cushion according to the multicell that such scheme is manufactured more, air cushion that equally can be in aforementioned patent applications, there is not burdensome thick thick rim, be convenient to FOLD AND PACK, accumulating, use, maintenance, be beneficial to production again, too can with the supporting use of the miscellaneous part described in the aforementioned patent applications (source of the gas controller, airway etc.).And, reducing owing to arrange the width of communication passage on the edge of air cushion, the chamber utilization rate improves, and uses air cushion so this modified model air cushion not only can be used as the bed of preventing and treating decubital ulcer, also can be used as the anti-tired health air-pad on various chaise longues, the seat more easily.

Below in conjunction with accompanying drawing this utility model and embodiment are described.

Fig. 1 is the whole chambers and the layout sketch map of pancake communication passage on pad of the 4 groups of air cushions in one 12 Room.

Fig. 2 is with the stacked up and down cross-sectional configuration sketch map when bonding of the pancake communication passage of surrounding edge structure.

Fig. 3 is with the stacked up and down cross-sectional configuration sketch map when bonding of the pancake communication passage of pancake pipeline configuration.

Fig. 4 be with the pancake communication passage of surrounding edge structure with the stacked cross-sectional configuration sketch map when bonding in the communication passage space of pancake pipeline configuration.

Referring to Fig. 1, (1) is the pad layer, (2) be upper layer film, (3), (4), (5), (6) are respectively the pancake communication passage of 4 groups of chambers, wherein (3) and (5), (4) are stacked up and down mutually with (6), and (7) are the short pancake intercommunicating pores between chamber and the pancake communication passage, and it also can be with the fusiformis valve nozzle replacement of using on the common air cushion, (8) be that the chamber group is led to the outer turnover conductance hole of air cushion, (9) are the chamber form lines.

Among Fig. 2, (1) is the pad layer, (2) be upper layer film, (3) be the surrounding edge that constitutes underlying pancake communication passage, (4) be the surrounding edge of putting the pancake communication passage on constituting, (5) be the barrier film between the stacked communication passage up and down, it must use gastight rubber plastic film or be coated with the rubber and plastic fabric.

Among Fig. 3, (1) be the pad layer, (2) are upper layer films, and (3) are the pancake pipelines that constitutes the underlying communication passage, (4) be the pancake pipeline of putting communication passage on constituting, manufacture (3), (4) material can with pad and the bonding unlikely again mutual gas leakage of upper strata mould.

Among Fig. 4, (1) is pad, and (2) are upper layer films, and (3) are the pancake pipelines that constitutes the underlying communication passage, and (4) are the surrounding edges of putting communication passage on constituting, be here rely on the selection of (3) guarantee (3) and on put between the communication passage and can not leak gas.

Claims

1, a kind of usefulness is coated with the rubber and plastic fabric, or rubber plastic film, or other gastight thin-film materials, organize air cushion through the modified model multicell that bonding, hot pressing or sewing tech are manufactured more, by pad, upper layer film, be clipped in that communication passage constitutes between many groups chamber between pad and the upper layer film and multichannel chamber, it is characterized in that the chamber group that described multicell is organized on the air cushion more counts n greater than 2, between the multichannel chamber communication passage in the chamber outside with the perpendicular a pair of air cushion edge of chamber, be made into be clipped between pad and the upper layer film, stacked multichannel pancake communication passage up and down.

2, modified model multicell as claimed in claim 1 is organized air cushion more, it is characterized in that, the stacked up and down multichannel pancake communication passage that described multicell is organized on the air cushion more all constitutes with surrounding edge, but mutually with gastight rubber-plastics material or be coated with the rubber and plastic fabric and separate.
