Description
Technical field
The present invention relates to the mattress of the applicable pre-counteracting bedsores that a kind of preventing effectiveness being called as the symptom of pressure ulcer (Japanese: bed wipe れ) or decubital ulcer occurred sometimes the patient of bed state is improved etc., particularly a kind of carried out in conjunction with behaviour in service optimization and improve the mattress that improve nursing/medical fitness of the improvement of spatter property etc. by improving the performance being suitable for cleaning.
Background technology
For the patient that the old people of so-called bed state, the people that recuperates are such, likely can there is the symptoms such as pressure ulcer owing to keeping constant posture in bed for a long time always, therefore, need often to carry out the nursing such as postural change.Certainly, when carrying out such nursing such as sufficient postural change, body wipe to patient, can prevent the so-called decubital ulcer being called as pressure ulcer from occurring to a great extent, but the present situation of carrying out nursing or carry out nursing at home in current public place is be difficult to seek desirable artificial nursing.
There is decubitus symptom according to such present situation to seek prevention in device, proposing some schemes.The starting point of such scheme is develop from such as lower angle mostly, this angle is: pressure concentrates on the such as rumpbone position etc. as the multiple position of decubital ulcer, therefore tackle from the direction of reducing this pressure such, or occur that decubitus symptom is set out by the starting point that ventilative state extreme influence is such, to guarantee breathability.
But, in common researcher, occur in the process of the reason of decubitus symptom in supposition, this breathability certainly needless to say, it is known that to concentrate the direction to the multiple position of decubitus symptom to carry out improving from pressure release be also very effective, as getting rid of the concentrated means of such pressure, propose the kinds of schemes such as air matting, foam mattresses (Foam mattress).As above-mentioned air matting, there is the method controlling air pressure or switch controlled pressure partly, although the eliminating effect that pressure is concentrated is higher, but also there is such problem: the uncontrollable pressure when having a power failure, further, sometimes sense of discomfort is caused because of distinctive the rocking of air matting, and, air matting carries out postural change, when being moved on air matting by user (by caregiver), is easily become unstable etc. by the posture of caregiver and caregiver.On the other hand, foam mattresses is the mattress using the expanded materials (elastic foamed body) such as the mattress of the expanded materials (elastic foamed body) such as monolithic foamed polyurethane or stacked foamed polyurethane, it has following feature, namely do not need as air matting by dynamic Control pressure, therefore silent oscillation mattress is also referred to as, this mattress can improve the problem of above-mentioned air matting, is therefore mostly used in the medium or lower user of decubital ulcer degree.But, for materials such as the foamed polyurethanes usually utilized by the mattress material as bedding, concentrate partly adopting the pressure that position easily occurs under the harder material context of hardness, therefore exist and bring out the tendency occurring decubital ulcer, on the other hand, although have pressure dissipation effect when softer, but can pressure release sacrad position etc. concentrate, but the position of patient can be caused to sink and bend, and bring out other pathological changes etc., above-mentioned each situation all has the technological deficiency of antinomy.
Present applicant has proposed the new technique of the technical problem for solving such foam mattresses, and obtain the authorization as No. 4674943rd, Japanese Patent " prevent pressure ulcers with pad " (with reference to patent documentation 1), and it is implemented product and commercially gets a good review and approved.
The spinal column that this technology is conceived to user is multiarticulate situation, the principle of invention is, along the direction orthogonal with the spinal column of user, the gel film of multi-disc strip is configured in the interlayer of foam pad material, gel film and each position elastic deformation on longitudinally accordingly (elongation strain) of sleeping position being variform on height direction, and as hammock, keep user (supporting role).Now, ideally: gel film extends all the time and acts on user as hammock on longitudinally.
From such a viewpoint, the applicant obtains such new discovery shown below in the process proceeding technological development.Namely, find: the foam pad material utilizing monolithic to be configured in the upper strata of gel film covers the one side of gel film significantly, thus along with user position of lying sinking and produce tensile stress in all directions at the foam pad material on this upper strata, therefore loading (stress) direction acting on gel film is also various, so a part for loading is not embodied in using of making above-mentioned gel film extend along longitudinally, supporting role is not fully utilized, and has room for improvement.
And except such new discovery, for for this type of nursing/therapeutic medical utensil, according to the difference of the health of each user individuality etc., the content be required is also different, and is required technique improvement one to one all the time.This concrete technical requirement refers to, such as to the improvement that the cushion material distortion caused because of weight differences, elasticity function reduce, or refer to make that needs frequently stand up the user of (postural change), its caregiver easily frequently stands up the improvement of (postural change), and refer to Security Countermeasures when sitting in bed, and refer to and carry out the countermeasure etc. of cleaning/sterilizing etc. by certain hour interval.

Below, an example of the embodiment according to Fig. 1 ~ Fig. 4 specifically describes the present invention.First, illustrate that the mattress that improve nursing/medical fitness of the present invention is (hreinafter referred to as mattress.) the summary of structure.
In figure, the mattress shown in Reference numeral 1 is mattress of the present invention, and it is layered on suitable bed B, for user P mainly with back floating position recumbency.
In addition, in figure 3, eliminate drawing the bottom surface of mattress 1, the bottom surface of mattress 1 is flat condition.In addition, in figure 3, the gel film 3 drawn by dotted line is located at inside with the state that cannot confirm from external view.
Mattress 1 of the present invention has following main member and forms: elastic foamed body 2, and it is at least made up of basic unit's portion's elastic foamed body 20 and upper layer part elastic foamed body 21; The gel film 3 of multi-disc strip, it is located between above-mentioned basic unit portion's elastic foamed body 20 and upper layer part elastic foamed body 21, and this elastic foamed body 2 is covered for use by emulsion sheet 11 with gel film 3.Certainly, preferably, when reality uses, also at least upper surface of this emulsion sheet 11 with the use of sheet 6, change frequently tackling.The longitudinally of the gel film 3 of above-mentioned multi-disc strip is the direction orthogonal with the long side direction of elastic foamed body 2 (or mattress 1), and is configured to state roughly arranged side by side in the scope of the gel film 3 of this multi-disc strip on the long side direction of elastic foamed body 2 (or mattress 1).This configuration mode be equivalent to make the longitudinally of the gel film 3 of multi-disc strip be with the height direction of user P (namely, spinal column direction) orthogonal direction and be configured to state roughly arranged side by side in the scope of the gel film 3 of this multi-disc strip on the height direction of user P, by adopting such configuration mode, the gel film 3 of strip can be made to extend in the longitudinal direction and play the support effects acted on user P as hammock.
Wherein, for above-mentioned orthogonal, do not require it must is strict vertical, as long as the longitudinally being configured to gel film 3 in the scope that can play above-mentioned support effects as hammock is roughly the width of elastic foamed body 2.
And, more preferably, the structure of the sidepiece hard portion 4 that mattress 1 is arranged for the long edge had along mattress 1 as Fig. 1 ~ Fig. 4, the stability at seat to be used for seeking to prevent user P from coming off from mattress 1, under the state being seated at the bed B being covered with this mattress 1.Basic unit's portion's elastic foamed body 20 and upper layer part elastic foamed body 21 all can arrange this sidepiece hard portion 4, if but produce larger difference of hardness (nonhomogeneous hardness) in the upper aspect of mattress 1, there is the situation that seat stability is impaired, therefore preferred this sidepiece hard portion 4 is located at basic unit's portion's elastic foamed body 20.
In addition, gel film 3 be for as main purpose of the present invention pre-counteracting bedsores and maintain the good effective component of sleeping position, will this gel film 3 be provided with and the position being provided with foam block 22 described later is above it called supporting role portion 5.
Below, above-mentioned each member of formation is described.First, as an example of elastic foamed body 2, the elastic foamed body 2 that employing length is 1950mm, width is 780mm, thickness is the shape of about 50mm ~ 200mm, and this elastic foamed body 2 has resilience (being sometimes also called for short elasticity), as an example of material, the foamed resins such as application foamed polyurethane.Wherein, above-mentioned size, material and above-mentioned elastic size, compression/recovery characteristics (displacement on compression direction and the relation of bounce) can according to the bodily form of user P, the character that require mattress 1 and suitably changing.At this, the elasticity of elastic foamed body 2 (basic unit's portion's elastic foamed body 20 and upper layer part elastic foamed body 21 are too) comprises the viscoelasticity with viscosity element.
Wherein, as above-mentioned foamed resin, separated foam body or continuous air bubbles body can be applied, but from the viewpoint of breathability, the foamed resin of advantageous applications continuous air bubbles body.In addition, from the viewpoint improving breathability/water penetration further, more preferably, adopt by the film of bubble remove and achieve connectionizations without film foaming body (without film bubble foam: membrane-free foam), this without film foaming body can by utilization fragmentation (Japanese: Network ラ ッ シ Application グ) method, alkali treatment method, blasting procedure etc. carry out membrane removal process to the foamed resin after molding and obtain.
Then, the hardness of the elastic foamed body 2 in each portion is described.First, preferably, the hardness of basic unit's portion's elastic foamed body 20 is more than the hardness of upper layer part elastic foamed body 21, as the mattress 1 as illustrated in Fig. 1 ~ Fig. 4, portion of basic unit 20 by the first portion of basic unit elastic foamed body 20a and the second portion of basic unit elastic foamed body 20b this two-layer form when, be preferably set to along with hardening successively away from above-mentioned gel film 3 on the thickness direction of mattress 1.As an example, the hardness of above-mentioned upper strata elastic foamed body 21 is set as 50N ~ 120N (according to Japanese Industrial Standards (JIS) K6400-2: compression 25%), and makes the hardness of basic unit's portion's elastic foamed body 20 be more than the hardness of upper strata elastic foamed body 21 (harder).
In addition, sidepiece hard portion 4 is formed by than foamed resins such as above-mentioned basic unit portion's elastic foamed body 20 and the hard hard of upper layer part elastic foamed body 21 (high rigidity or high least) foamed polyurethanes.
In addition, the hardness of elastic foamed body 2 also can be made different from the upper body of user P, waist, each position that lower limb are corresponding.
Then, gel film 3 is formed with the size that such as length is 450mm, width is 80mm, thickness is about 2mm.Further, this gel film 3 material can application examples as olefines gels etc. such as the cosmo PE gels (registered trade mark) of the polyurethane gles such as the skin gel (people's flesh: registered trade mark) of the silicon materials such as Amada Co., Ltd. TAICA α gel (ア Le Off ァ ゲ Le: registered trade mark), Japanese エ ク シ ー ル コ ー ポ レ ー シ ョ Application, Japanese コ ス モ Meter device society.In addition, the hardness of preferred gel film 3 is the scope of such as asker hardness number C0 ~ 40 (according to SRIS 0101 standard) or needle penetration (JISK220725 DEG C) 50 ~ 250.At this, gel in the present invention also comprises the concept of so-called elastomeric material, be not limited to above-mentioned illustrative gel rubber material, the known elastomeric materials such as silicone rubber, polyurethane rubber, acrylate rubber can also be applied in the scope not damaging action effect of the present invention.In addition, above-mentioned size and hardness can according to the physical qualifications such as the bodily form of user P, body weight, the character that require mattress 1 and suitably changing.Such as, when the body weight of user P is heavier, carry out such design alteration: increase hardness, or increased in size is to increase compression area, thickens the thickness etc. of gel film.
In addition, in the embodiment shown in Fig. 1 ~ Fig. 4, gel film 3 is the lamellar of same thickness, but consider that pressured state is different because of the difference of the body part of user P, also can adopt and make varied in thickness accordingly with user P body part or make the changes such as elongate in shape beyond rectangularity and the such structure of the corresponding pressured state of pressure valve.
Wherein, " hardness " usually use by the Durometer measurements corresponding with the scope of hardness to value, in the present invention, in order to limit the hardness in the soft region of askerC hardness in more detail, and limit in conjunction with needle penetration.
In addition, as long as can guarantee to have suitable breathability for covering overall emulsion sheet 11, knitting eye, to have loft as far as possible then better.Thus, as an example, can to apply compared to weaving closer to the so-called La Sheer of state of braiding through three-dimensional knit fabrics such as volumes.In addition, preferably this emulsion sheet 11 itself can be taken off from mattress 1 and is cleaned, but the emulsion sheet of the more preferably process that the treatment function such as application implementation further raising mildew resistance, antibiotic property is such.
In addition, the sheet 6 being located at least upper surface of such mattress 1 can be changed more continually, can select suitable sheet according to the situation of patient P, such as, reply when considering incontinence and select to have the sheet etc. of water proofing property.
In addition, for the concrete form of mattress 1, the thickness of elastic foamed body 2 entirety is about 50mm ~ 200mm, clip gel film 3 and be located at the elastic foamed body 2 of lower floor for basic unit's portion's elastic foamed body 20, the elastic foamed body 2 being located at the top (user side) of gel film 3 is upper layer part elastic foamed body 21.In addition, when upper layer part elastic foamed body 21, basic unit's portion's elastic foamed body 20 are for multi-ply construction, same definition is also adopted.As a result, gel film 3 to be set as in sandwich shape folder between which or interlayer at least partially.
Then, illustrate the change of elastic foamed body 2, first, the elastic foamed body 2 of the mattress 1 shown in (a) of Fig. 5 is made up of basic unit's portion's elastic foamed body 20 and upper layer part elastic foamed body 21.In addition, the elastic foamed body 2 of the mattress 1 shown in (b) of Fig. 5 is made up of basic unit's portion's elastic foamed body 20 and upper layer part elastic foamed body 21, this basic unit's portion's elastic foamed body 20 is made up of the first portion of basic unit elastic foamed body 20a and overlapping the second portion of the basic unit elastic foamed body 20b be located on this portion of the first basic unit elastic foamed body 20a, and this upper layer part elastic foamed body 21 overlaps on this portion of the second basic unit elastic foamed body 20b further.In addition, the elastic foamed body 2 of the mattress 1 shown in (c) of Fig. 5 is configured to: the two side portions of the second portion of basic unit elastic foamed body 20b of the elastic foamed body 2 shown in (b) of Fig. 5 excised, and arrange sidepiece hard portion 4 herein.In addition, utilize known bonding agent, welding process etc. that contact surface respective to basic unit's portion's elastic foamed body 20, upper layer part elastic foamed body 21, sidepiece hard portion 4 and gel film 3 is bonded (also referred to as being adhesively fixed), and be assembled into mattress 1.In addition, there is no need the whole face of gel film 3 to be adhesively fixed, as long as at least both ends of gel film 3 are bonded and fixed to basic unit's portion's elastic foamed body 20 and/or upper layer part elastic foamed body 21 in order to the support effects obtained as hammock.In addition, in the example of the multi-ply construction be made up of above-mentioned first portion of basic unit elastic foamed body 20a and above-mentioned second portion of basic unit elastic foamed body 20b at basic unit's portion's elastic foamed body 20, as long as be adhesively fixed to above-mentioned second portion of the basic unit elastic foamed body 20b of major general and gel film 3 and upper layer part elastic foamed body 21, above-mentioned first portion of basic unit elastic foamed body 20a and above-mentioned second portion of basic unit elastic foamed body 20b can be bonded together.
In addition, in the mattress 1 shown in Fig. 1 ~ Fig. 4, be formed with the inclined-plane declined towards inner side at the medial part of sidepiece hard portion 4.In addition, in Fig. 1 ~ Fig. 4, illustrate gel film 3 be not positioned at mode above sidepiece hard portion 4, but the mode of overlooking lower gel film 3 and configuring overlappingly with sidepiece hard portion 4 can be adopted, thus the situation that the end that can obtain gel film 3 is held stably, and more reliably can obtain the support effects as hammock based on gel film 3.In this case, preferred bonding Strengthening Hole 31 described later is formed in the position of the top being positioned at sidepiece hard portion 4.
In addition, the bottom surface of the mattress 1 shown in Fig. 3 is flat condition, but in order to the inclination/lifting (Japanese: ギ ャ ッ チ ア ッ プ) of easily following a B, also can to the slot machining of the bottom surface enforcement of undermost basic unit portion's elastic foamed body 20 along the width of mattress 1.
In addition, at the position in above-mentioned supporting role portion 5, this divided position of opening, by arranging clearance portion 24 and dividedly opening, is foam block 22 (in (c) of (a) ~ Fig. 5 of Fig. 5, eliminating the diagram of foam block 22) by upper layer part elastic foamed body 21.In addition, upper layer part elastic foamed body 21 not only can comprise monolayer constructions will, can also comprise multi-ply construction, below, is described, for multi-ply construction, is described later for the situation that upper layer part elastic foamed body 21 is monolayer.In addition, in the upper layer part elastic foamed body 21 of monolayer constructions will shown below, (b), (c), (e) of Fig. 6, (f), the upper layer part elastic foamed body 21 shown in (g) have linking part 23, it similarly is at first sight multi-ply construction, but as described below, linking part 23 for linking foam block 22, and is integrated with foam block 22 one-tenth, is therefore in fact considered as monolayer constructions will.
As shown in (a) of Fig. 6, above-mentioned foam block 22 is configured on basic unit's portion's elastic foamed body 20 to be divided into state independent of each other when analysing and observe, except this mode, the structure utilizing linking part 23 to link in bottom as shown in (b), (c) of Fig. 6 can also be adopted in the scope not damaging feature of the present invention, interlock namely between gel film 3 and foam block 22.First, in the structure shown in (b) of Fig. 6, independently the foam block 22 of prism-shaped is traverse shape, makes the elastic foamed body material of formation a slice linking part 23 be positioned at the bottom of this foam block 22, and they are bonding or be welding together.In addition, in the structure shown in (c) of Fig. 6, independently the foam block 22 of prism-shaped is traverse shape, makes the elastic foamed body material of square bar shape be positioned at the lower side of this foam block 22, and they are bonding or be welding together.Above-mentioned linking part 23 such as plays such effect: being adhesively fixed between reinforced foam block 22 and gel film 3 and/or between foam block 22 and basic unit's portion's elastic foamed body 20.In addition, when the surface of gel film 3 has cohesive (viscosity), by the surface making linking part 23 cover gel film 3, also have thus and prevent dust etc. to be attached to gel film 3 and the effect of being made dirty by gel film 3.In addition, the material of linking part 23, character can be identical with the material of foam block 22, character, also can be different.The foam block 22 utilizing linking part 23 to link like this has certain interval each other, and this interval is called clearance portion 24.
