The optimization of condition and the performance being suitable to clean by improvement improve the improvement of spatter property etc. to improve nursing/medical treatment applicable
The mattress of property.
Background technology
For the old people of so-called bed state, the such patient of the people that recuperates, it is possible to can be due to the most in bed
It is always maintained at constant posture and the symptoms such as pressure ulcer occur, accordingly, it would be desirable to often carry out the nursing such as postural change.Certainly, right
In the case of patient carries out the nursing such as such sufficient postural change, body wipe, it is possible to prevent what is called to a great extent
Be referred to as pressure ulcer decubital ulcer occur, but the present situation carrying out in current public place nursing or carrying out at home nursing is
It is difficult to seek to the most artificial nursing.
In order to seek prevention in terms of device, decubitus symptom occurs according to such present situation, it is proposed that some schemes.Above-mentioned
The starting point of scheme mostly follows from angle and develops, and this angle is: pressure concentrates on as the multiple position of decubital ulcer
Such as rumpbone positions etc., therefore tackle from the minimizing such direction of this pressure, or occur that decubitus symptom is subject to ventilative state
The such starting point of extreme influence is set out, to guarantee breathability.
But, in common researcher, during speculating reason decubitus symptom occur, this breathability certainly need not
Say, known concentrate from pressure release that to carry out improving to the direction at the multiple position of decubitus symptom be also extremely effective, as eliminating
The means that such pressure is concentrated, it is proposed that the kinds of schemes such as air matting, foam mattresses (Foam mattress).As upper
State air matting, there is the method controlling air pressure or switching control pressure partly, although the eliminating effect that pressure is concentrated is relatively
Height, but there is also such problem: the uncontrollable pressure when having a power failure, and, sometimes draw because of distinctive the rocking of air matting
Play sense of discomfort, and, air matting carries out postural change, when being moved on air matting by user (by caregiver), quilt
The posture of caregiver and caregiver easily becomes instability etc..On the other hand, foam mattresses is to use monolithic foamed polyurethane etc.
The mattress of the expanded materials (elastic foamed body) such as the mattress of expanded material (elastic foamed body) or stacking foamed polyurethane, its
There is following feature, i.e. need not by dynamic Control pressure, the most also referred to as silent oscillation mattress as air matting, should
Mattress can improve the problem of above-mentioned air matting, is therefore used mostly in the medium or relatively low user of decubital ulcer degree.So
And, the material such as the foamed polyurethane utilized for being normally used as the mattress material of bedding, using the harder material of hardness
The pressure being susceptible to position in the case of material is concentrated partly, therefore there is induction and the tendency of decubital ulcer occurs, on the other hand, relatively
Although having pressure dissipation effect in the case of soft, but pressure release sacrad position etc. can concentrate, but patient can be caused
Position sinks and bends, and induces other pathological changes etc., and above-mentioned each situation is respectively provided with the technological deficiency of antinomy.
Present applicant has proposed the new technique of technical problem for solving such foam mattresses, and conduct
Japanese Patent Publication No. 4674943 " prevent pressure ulcers with pad " (with reference to patent documentation 1) obtains and authorizes, and it implements product commercially
Get a good review and be recognized.
It is multiarticulate situation that this technology is conceived to the spinal column of user, and the principle of invention is, along the ridge with user
The gel film of multi-disc strip is arranged in the interlayer of foam pad material by the orthogonal direction of post, and gel film with on height direction is
Elastic deformation (elongation strain) on longitudinally accordingly of each position of the sleeping position of variform, and keep as hammock
User (supporting role).Now, it is also desirable to: gel film extends and to making as hammock all the time on longitudinally
User acts on.
From such a viewpoint, the applicant obtains shown below such during proceeding technological development
New discovery.I.e., it was found that: utilize the foam pad material on the upper strata that monolithic is arranged in gel film to cover the one of gel film significantly
Face, thus along with the sinking of the lain position of user, the foam pad material on this upper strata produces tensile stress in all directions, because of
This loading (stress) direction acting on gel film is also various, so a part for loading is not embodied in makes above-mentioned gel
Sheet is along using that longitudinally extends, and supporting role is not fully utilized, and has room for improvement.
And, in addition to such new discovery, for for this type of nursing/therapeutic medical utensil, individual according to each user
The difference of health etc., the content being required is the most different, and is required technique improvement one to one all the time.This is concrete
Technology require to refer to, the improvement such as the cushion material deformation caused because of weight differences, elastic function reduced, or refer to into
The needs are made the most frequently to stand up (postural change) for frequently standing up the user of (postural change), its caregiver
