Abstract

The utility model provides an inflated mattress, comprising a mattress surface, a mattress bottom and a gas storing inner cavity which is formed by the envelop of the mattress surface and the mattress bottom, wherein, after the gas storing inner cavity is inflated, the mattress surface forms a strip-shaped gas passage structure system which is two sets of strip-shaped gas passages arranged alternately and alternated by each other, the strip-shaped gas passages are inflated and deflated by a gas duct forming an external connection with an air compressor. The utility model has the advantages of simple structure and convenient manufacture and maintenance, and for the realization that two sets gas passages are inflated alternately, can improve the gas permeability and realizes the automatic shifting between patients and the contact points of the mattress surface to prevent the growth of decubitus.

Description

A kind of inflatable packer

The utility model relates to mat, refers to inflatable packer especially, belongs to the accessory of sick bed etc.

Mat will be counted inflatable packer for best at present as the sick bed accessory with SC facility.Inflatable packer is that rubber or plastics constitute generally by having had flexible material, and it has certain thickness, connect need cutting after, adopt the sealed knot technology to form one by the inner-cavity structure that can store gas in pad face and rebasing its that surrounds; In addition, for improving the gas permeability of inflatable packer, its pad face and rebasing sealed knot make that generally the pad face forms the strip air passage structure after inflation.The inflatable packer of prior art generally has two kinds: the one, and whole inflatable packer has only one to deposit the gas inner chamber, also is that all strip air flues are and are interconnected, and has only an external air compressor of wireway; Another kind of inflatable packer then has a plurality of gas inner chambers of depositing, and also is that all strip air flues are that each does not communicate, and form one and independently deposit the gas inner chamber, and each inner chamber all has an external air compressor machine of wireway.Obviously, though the former structure is simple, because have only one to deposit the gas inner chamber, charges and discharge gas and work simultaneously for all strip air flues, the contact point relative fixed of this feasible pad face and human body is easy to generate bedsore, and is therefore also impracticable; Then a kind of inflatable packer, that can realize in addition so each inner chamber in principle charges and discharge gas separately, but it is actual and remarkable because strip inner chamber number is many, in addition, since each deposit the gas inner chamber wireway, complex structure all arranged, produce with maintenance all inconvenient, if reduce the wireway number, certainly will will increase the width of each strip air flue, thereby make patient the body point do not feel well because of the gas permeability difference.

The purpose of this utility model, provide a kind of inflatable packer, its pad face forms narrow round horizontal stripe shape, not only good permeability, even also can realize easily human body when not standing up with the change displacement of pad face contact point, have simple in structure, easy to maintenance and can obviously prevent the characteristics that bedsore is grown.

Technology division of the present utility model is as follows: this inflatable packer comprises pad face, rebasing, this pad face and rebasing sealed knot form the inner chamber that can deposit gas in it, this pad face is being deposited gas inner chamber inflation back formation strip air passage structure, wherein, this strip air passage structure system forms two groups and is distributed in distance and mutually every the strip air flue of look, these two groups of air flues respectively be provided with a wireway with external air compressor machine realize its separately charge and discharge gas.In addition, according to the embodiment of the utility model, above-mentioned two wireways connect air compressor machine via two valves respectively, and connect blast pipe through other two valves.

The utlity model has following advantage: therefore easy to manufacture although 1 the utility model has many bar shaped air flues because have only two external air compressor machines of wireway, also be convenient to maintenance; 2, owing to adhering to two groups separately, strip air flue of the present utility model independently deposits the gas inner chamber, therefore easily realize that it takes turns mould and charge and discharge gas, even, prevent that due to illness body produces bedsore with the pad face because of crossing to contact for a long time so do not stand up the automatic shift that also can realize patient and pad face contact point under the mobile situation patient; Therefore 3, because strip air flue of the present utility model is distributed in distance, can be designed to narrower round horizontal stripe shape, make to couch comfortablely, and under the situation of alternately inflating, guarantee the gas permeability that it is necessary.

Provide embodiment of the present utility model below in conjunction with accompanying drawing, and be described in further detail.

Fig. 1 is the structural representation of the utility model inflatable packer.

Fig. 2 is the A-A view of Fig. 1.

Fig. 3 is the B-B view of Fig. 1.

Fig. 4 be the utility model inflatable packer charge and discharge the gas schematic diagram.

The utility model inflatable packer adopts two structures of depositing the gas inner chamber, utilizes one to fill a mode of putting, and makes the pad face form waveform, realizes the automatic shift of human body and inflatable packer pad face contact point.With reference to Fig. 2-3, the utility model inflatable packer is after inflation is heaved, its pad face 1 forms narrower round horizontal stripe shape, and, as shown in Figure 1, the utility model inflatable packer forms two groups of strip air passage structures by the gas inner chamber system that deposits that pad face 1 becomes with rebasing 2 sealed knots, and wherein strip air flue 3 is distributed in distance with strip air flue 4, but they are then isolated obstructed fully each other, also promptly form two and independently deposit the gas inner chamber.In addition, this two groups of air flues 3,4 each link to each other with extraneous air compressor machine via the wireway 31,41 that is fixedly arranged in rebasing 3 and charge and discharge the gas (see figure 4) with what realize that it deposits the gas inner chamber separately.The utility model inflatable packer pad face 1 forms 2 centimetres wide, 2 centimetres high round horizontal stripe shape after inflation, both guaranteed the comfortable of patient body's sense, has guaranteed necessary gas permeability again because it is alternately inflated.

As can be seen from Figure 4, the inflation/deflation structure that links to each other with air compressor machine and blast pipe via valve F1-F4 respectively of above-mentioned wireway 31,41.Because two groups of air flues the 3, the 4th are separate, therefore charge and discharge gas with can realizing its one after the other.Also promptly when air flue 3 inflation, 4 venting of air flue are shown in the solid line and dotted line of pad face 1 among Fig. 4; Naturally also can make it to charge and discharge simultaneously gas, these processes need only the switch of by-pass valve control F1-F4 and can realize easily.For example, when air flue 3 inflations, during air flue 4 venting, as long as open valve F1, F4, valve-off F2, F3 get final product; If will make air flue 3 venting, air flue 4 inflations then need valve-off F1, F4, and open valve F2, F3.If two air flues 3,4 are inflated simultaneously, then should open valve F1, F3 and valve-off F2, F4; Otherwise,, can exit simultaneously when valve-off F1, F3 when opening valve F2, F4.In addition, in view of the switch that charges and discharge the air pump by-pass valve control of the utility model inflatable packer is realized,, realize charging and discharging the timing controlled of gas easily therefore by means of existing automatic control technology, perhaps come remote control by patient, this has practical value especially for the heavy patient that those are difficult for standing up.
