The utility model is related to medical instruments field, particularly a kind of anti-bedsore mattresses.
Bedsore long-term bed does not play the skin disease that person most often easily violates, and bedsore Crack cause is also many, mainly divides four
1st, the patient of long-term bed due to bed rest time it is long, can not arbitrarily stand up in bed, rumpbone, ischial tuberosity, femur
Greater trochanter etc. area skin is often subject to the extruding of body, and so, the blood circulation of skin becomes very poor；
There is obstacle in the 2nd, patient of neurotrosis, vegetative nervous function, influence nerve makes disease to the trophic function of skin
People is susceptible to skin injury, necrosis and ulcer；
3rd, skin can not be often ventilated, is also one of the reason for being formed；
4th, sanitary condition is poor.Patient's moving difficulty of long-term bed is difficult to ensure personal hygiene, such as infrequently washes
Bath, changes one's clothes, and this just easily generates bedsore very much, difficult to treat after generation.
Bedsore is generated under the conditions of four more than, if this four conditions can not be changed after generation, bedsore will continue to continue
Hair deteriorates, it is more difficult to cure.Because the blood circulation of ulcer surface is very poor, wound metabolic stress in itself is caused, so being not easy to heal
Close, form the long-term disunion surface of a wound.
Existing bedsore cushion, on making material, typically using structures such as mattress, water cushion, foam-rubber cushion, air ring, cotton pads,
Wherein by most commonly seen with mattress, water cushion, foam-rubber cushion,
It is approximate on air ring and mattress principle, simply there is a little difference in structure；In mattress, performance it is best be band
There is the mattress of automatic programme control device and some airbags, by ventilating and deflating, the expansion of different airbags in control mattress
Wave is produced with shrinking, with the fluctuating of wave, the position that suffers oppression of human body converts once at regular intervals, equivalent to disease
People stands up, and high-frequency stirring plays whole body massage, stimulates circulation, the effect of relaxed muscle.Between wave is generated simultaneously
Gap, makes air circulate naturally, allows skin to have a breath of fresh air for 24 hours.It is so not only safe, effectively prevent the hair of bedsore
It is raw, and manpower is fully liberated, instead of manually stand up completely.Preferably, but there is problems with the type mattress effect,
Construction is complicated fragile, it is necessary to real-time function, consumes energy larger；Whole cost is also higher.
Normal air pad, air ring, water cushion is approximate in structure, is all that certain medium is filled with utricule, heaves utricule,
Only difference is that normal air pad, the medium in air ring is air, and the medium in water cushion is water, the type bedsore cushion low cost
It is honest and clean, but there is poor air permeability in the type mattress, and comfort level is low, mattress, and air ring also haves the shortcomings that radiating effect is poor.
Foam-rubber cushion, cotton pad and normal air pad, air ring, water cushion structure proximate, medium are different, and comfort level increases, but
It is still have the shortcomings that poor air permeability, radiating effect are poor.
Except the mattress with automatic programme control device and some airbags, other kinds of mattress, if without special
People guards, and patient still easily forms bedsore.
The content of the invention
The purpose of this utility model is the anti-bedsore mattresses for providing a kind of rapid heat dissipation, having breathed freely.
The purpose of this utility model is achieved through the following technical solutions：It includes that TPR layers of upper strata and the PU of lower floor is foamed
Layer, is brought into close contact between wherein TPR layers and PU foaming layers.
For than prior art, the utility model has the advantage of：1st, with good thermal diffusivity and gas permeability；2nd, bullet
Property is moderate, can avoid the extruding undue to skin；Barycentre steadiness is kept simultaneously, it is to avoid user rocks；3rd, it is with low cost, just
In batch production and popularization, the burden of patient is also relatively small.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the structural representation of PU foaming layers.
Fig. 3 is the structural representation that TPR layer surfaces are provided with sunk structure
Label declaration：1TPR layers, 2PU foaming layers, the cellular hole posts of 2-1,3 layer of cloths, 4 anti-skid cloths, 5 sunk structures.
The utility model content is described in detail with reference to Figure of description and embodiment：
It is as Figure 1-3 embodiment schematic diagram of the present utility model,
It includes the PU foaming layers of TPR layers of upper strata and lower floor, is brought into close contact between wherein TPR layers and PU foaming layers.TPR
Material (thermoplastic elastomer (TPE)) has many advantages, such as, various synthesis have been carried out with regard to TPR materials outside native land, it is applied to each and leads
Domain, TPR materials described herein are usually to use to be directed to the TPR materials that medicine and hygiene fieldses are used, the type material
The characteristics of itself has thermal diffusivity and good permeability, while can be adjusted to its hardness as requested, as requested can be with
Customization TPR the layer of different hardness, with this for consumer's selection, due to anti-bedsore mattresses making during, it is desirable to have it is certain
Thickness, if all can undoubtedly improve production cost using TPR materials, and if TPR is blocked up, although to elasticity effect not
Greatly, it is but very big on influence of radiating and breathe freely, so in making, certain thickness TPR materials can only be considered as, with human body
Discontiguous part, is replaced using other materials, and material considers there is certain degree of hardness, durable, low cost.After considering, it is believed that
It is relatively good using PU expanded material effects.
Layer of cloth is bonded with TPR layers of upper surface.In actually used process, TPR layers can be directly to enter with human body skin
Row contact, although radiating, hydrofuge (exhaust) is not affected, but user's comfort level has declined, therefore is considered on TPR layers
Surface-bonded layer of cloth, to improve the comfort level of patient.
Described layer of cloth is to cover Lycra cloth or fluffing elastical cloth.
Anti-skid cloth is bonded with the lower surface of PU foaming layers.In general, anti-bedsore mattresses will be tried one's best and the buttocks of patient is pasted
Close, to improve using effect, but in actual use, due to the action of the position, patient of patient, be all likely to result in anti-cotton-padded mattress
Sore pad position skew, in order to avoid it is above-mentioned the occurrence of, therefore consider anti-bedsore mattresses lower surface set anti-skid cloth.
The cellular hole post of some up/down perforations is laid with described PU foaming layers.If using PU expanded materials, energy
Enough reduce anti-bedsore mattresses production cost, but a little influence can be caused on radiating effect, in order to avoid it is above-mentioned the occurrence of,
Therefore be provided with some cellular hole posts and radiated, on the other hand, using cellular hole post, can simultaneously ensure anti-bedsore mattresses
Bulk strength, moreover it is possible to save material.
In order to ensure product be applicable in the case of, reduce product cost, in General Design Process, it is considered to TPR layer with
The gross thickness of PU foaming layers is 3~7cm, and wherein TPR layers of thickness is 1.5~2.5cm.
Depression corresponding with human body underline is provided with TPR layers of surface.In order to ensure that skin regional can be received
Power is uniform, therefore consideration is provided with depression corresponding with human body underline on TPR layers of surface so that human body skin can be pasted with it
