Description

Air cushion for assisting in getting up

Technical Field

The utility model relates to the technical field of nursing beds, in particular to an air cushion for assisting in getting up.

Background

The elderly and some special people, such as post-operative patients, post-stroke patients, pregnant women, etc., have difficulty or even impossible to get up from the bed, and a large part of them have some self-care ability. Even the simple work of getting up and lying down during ordinary care has high demands on the physical ability of the operator, for which various care beds are on the market.

The nursing bed is manual and electric, the manual price is low, the structure is simple, the reliability is good, the electric function is strong, the use is convenient, but the structure is complex, and the price is high. An electric auxiliary uprighting device is arranged behind the electric auxiliary uprighting device, and the electric auxiliary uprighting device also utilizes a motor as a power supply to provide uprighting assistance.

However, these products have some defects, firstly, the basic framework made of steel is adopted, and the products are used in families and occupy large space. Secondly, all directly use the 220v power, or provide working power through the power adapter, but whichever one all has the danger of electric leakage, thirdly, in order to guarantee intensity and weight reduction, generally adopt hollow member welding to form, the mattress is thick has not necessarily comfortable, and thin then obviously can perceive the underlying hard thing, and the time is slightly long, very uncomfortable. Fourth, the cost of the product is high, especially the maintenance cost. Fifthly, the possibility of accidental injury exists, after the bed frame is turned up, an open space is left at the rear part, objects fall well, and hands can be clamped when the objects fall back, so that injury is caused. Sixth, the metal bed frame, even if treated without sharp corners, is still prone to cause bruising and the like.

Against this background, we therefore provide the alternative of using the bladder to form an appropriate cushion, providing the same functionality, and possibly improving the drawbacks.

Firstly, the air cushion is light and thin and is made of soft materials, and the influence on the comfort degree is small after the air cushion is folded.

Secondly, the air pump adopts 220VAC power supply, but is connected between air cushion and the air pump by the trachea, can provide excellent insulating properties, safe and reliable. Thirdly, the cost of the air pump is slightly higher, but the cost of the air cushion is low, the air cushion is easy to maintain, and the whole use cost is much lower. Fourth, and most importantly, there is no metal rod underneath, which greatly improves sleep comfort. Fifthly, when getting up, the whole air cushion is in a overflowing state, foreign matters and the like cannot be clamped in, and other people cannot be injured. Sixth, the whole is made of an airbag, and even if the airbag is accidentally knocked, the airbag does not cause great injury.

If only a common air cushion is used, products like an inflatable mattress or an inflatable sofa can have more limitations, for example, the requirements on the inflation quantity and the inflation speed of an air pump are higher, the power requirement is higher, so that either the noise is higher, or the volume is larger, when the second air cushion is folded, if the shape is not well processed, part of the air cushions can be overlapped, and the flatness can be poor. Thirdly, the air cushion has a short service life and is easily punctured, if the opening is large, the falling speed is too fast, so that the body is possibly injured, and fourthly, the air bag can shake in the inflating process, and the air bag is difficult to accurately stop at any position.

And a split 34 is provided between the air cells inside the air bag layer, the split 34 being provided on the fabric layer 5. Thus, the inner and outer layers of the air bag are of an assembly structure, not bonded, and the inner liner 6 of the inner layer can be simply replaced after the fabric layer 5 of the outer layer is opened by a zipper or a special sewing structure.

The air bag layer is of a double-layer structure consisting of the air-tight layer 6 and the fabric layer 5, the air-tight layer 6 is detachably connected with the fabric layer 5, and replacement and maintenance are convenient. The outer structural strength that provides can make whole gasbag bear higher atmospheric pressure, bear bigger load, provide reliable bearing capacity and push power to there is damaged back at the inlayer, effectively prevent gaseous quick release in order to maintain basic shape, the prevention has the physique of problem back gasbag to burst the back rapidly, probably to the harm that the user caused, can reduce substantially the requirement to the inlayer simultaneously, reduction in manufacturing cost.

The upper air bag 3 will inflate earlier than the lower air bag 4 and has a higher air pressure than the lower air bag 4, which can provide a pre-support for the human body similar to a whole, the upper air bag 3 actually provides a stable position state of reclining under the condition that the lower air bag 4 is not inflated, when the lower air bag 4 is inflated, the fan angle of the mattress is increased, the upper air bag 3 basically becomes a whole to rotate, an integral support structure for pushing the user to get up is provided, and the lower air bag 4 provides the main power and deformation part for pushing the user to get up.

Because the upper layer gasbag 3 can be regarded as the support that the user upper part of the body helped getting up after inflating completely, consequently the gasbag 4 of lower floor need not to fill completely in fact and just can promote upper layer gasbag 3 and turn over, the gasbag of lower floor only need provide locally promptly to the promotion of upper layer gasbag can, consequently can also adopt dispersed gas column.

Further, the lower layer air bags 4 are at least provided with two air bags, and the interiors of the two air bags are mutually communicated. After the multiple airbags are overlapped, a fan-shaped structure with a large integral angle is provided, and the function of assisting in getting up is completed. The sector angle of the upper layer air bag 3 is 25-30 degrees, the sector angle of each lower layer air bag 4 is 15-25 degrees, the sector angle of the three air bags after being overlapped is 45-75 degrees, and the upper layer air bag 3 is matched to finally provide support over 85 degrees.

In the present invention, the whole product is divided into 4 parts, which are composed of a bottom layer 1 of hard fabric at the lowermost part, a top layer 2 of coarse fabric, and an upper layer airbag 3 and a lower layer airbag 4 at the upper part, sandwiched between the bottom layer 1 and the top layer 2. Wherein the lower layer air bag 4 is separately arranged but communicated with each other, the upper layer air bag 3 is independently sealed, each layer air bag consists of a plurality of air chamber parts, such as a left air chamber part, a middle air chamber part and a right air chamber part, and the plurality of air chamber parts are communicated with each other. Wherein the bottom layer 1 of the hard fabric layer is still foldable, the bottom layer 1 provides the overall shape of the product and in combination with the other parts provides a substantially fixed support that prevents the air bag from rocking from side to side. The coarse fabric surface layer 2 provides good air permeability and provides a considerable thickness, so that discomfort caused by unevenness of the folded bottom air bag is greatly reduced, and the thickness of the surface layer 2 can be properly changed according to whether the bottom air bag exists or not, so that better flatness is obtained. The air bag is actually composed of an airtight layer 6 and a fabric layer 5, the outer layer is the fabric layer 5 and is composed of thin high-strength dense fabric such as nylon cloth and oxford cloth, and the inner layer is the airtight layer 6 and is formed by hot melting of materials such as pvc.

Regarding the overlapping of the air bag part, influence the planarization problem, we have introduced the air cushion layering method, and the air bag layer is fan-shaped structure after aerifing, in lower floor's gasbag 4, is divided into several independent layers with whole air cushion, just so can be reasonable reduce the layer height on every layer, reduce the layer height, there is not the gap in the middle of the shrink back, does not have hard thing, and the roughness is guaranteed easily, and the region of overlapping is peripheral, does not also influence the human impression and the comfort level that are in the intermediate position.

In addition, the air cushion layering is also beneficial to preventing the side wall from being too large, can provide good formed shape and deflated shape, and reduces the requirement and requirement on space in use.

Secondly, the sudden rupture of the air bag causes the falling back too fast, and a double-layer scheme of a double-layer air bag is introduced, wherein an air bag layer consists of an air-tight layer 6 and a fabric layer 5. The outer layer is made of fabric, so that the strength is good, and the service life is long enough. The inlayer uses sealed gasbag because of providing in inside and aerifys, consequently need not pile coating, also needn't bear very high tension, reduces by a wide margin the requirement of material, and the cost also can be lower, and 5 inboards on outer fabric layer can suitably coat sealing material, and when the inner bag was damaged, only outer sewing department can leak gas, and gas leakage speed will slow down greatly. That is to say, even if the inner bag bursts, there is the protection of skin, and whole air cushion can not damaged in the twinkling of an eye in fact, can effectual control fall-back speed.

If there is slow gas leakage very easily to be detected, even if gas leakage appears, can restart the air pump moreover, in time the tonifying qi, the air cushion can continue to bear sufficient load, can restore after packing up, continues to use after the restoration. The maintenance of this gasbag is also very simple, if the air pocket of supplementary air cushion of standing up breaks the condition, unpacks apart the skin, and change inside air pocket can.

In order to solve the stability problem in the inflating process, the air bag is arranged outside the vertical direction separation layer, at least two air chambers are arranged outside the air bag layer, the separation treatment is also carried out in the plane, and other volumes outside the air bag layer are larger than those inside the air bag layer.

After layering in the vertical direction, the upper layer air bag 3 is inflated firstly, in the inflation process, the surrounding air chambers in the horizontal direction are inflated firstly because of no load, when the inner side air bag bearing the weight of a human body starts to inflate, the surrounding air bags can provide certain bearing capacity and surround the middle air chamber, and by combining the hard fabric bottom layer 1 below, sufficient stability in the horizontal direction can be provided, all the air bags of the upper layer air bag 3 become a first stable state after being filled, and at the moment, a 20-26-degree half lying position is provided, so that a good body position which is beneficial to most of rehabilitation is achieved.

When needing to get up, inflate 3 gasbags below, because upper strata gasbag 3 above has been filled, there is considerable compressive capacity, combine the crude fabric surface course 2's of the superiors to hold back, the scope of rocking has received considerable restriction, 4 volumes of lower floor's gasbag are less than the upper strata in fact, consequently, the gas velocity is very fast, can get into the state of relative filling rapidly, the influence that the level instability brought can reduce by a wide margin, aerify the completion back, whole can provide 50-56 degrees, even 80 degrees angle of elevation, just can be convenient get up through leaning on one's side this moment.

In fact, the airbag does not need to fill the entire auxiliary device space, but only needs to provide sufficient load-bearing capacity and sufficient stability, in particular of the lower airbag 4. Therefore, the lower bladder 4 may be hollow or may be formed of several air columns.

The volume of the inflatable air bag is small when the inflatable air bag falls back, the filling magnitude is large when the inflatable air bag works, and the inflatable air bag is suitable for being used in a small space. The key of the rising assisting air bag is low cost, can complete basic functions and can provide proper help for more demanders.
