Description

Outer cover of artificial limb

This utility model relates to a kind of overcoat, particularly a kind of being nested with outside artificial limb, the prosthetic jacket that has practical function such as waterproof, convenient artificial limb knee bend and increase artificial limb external form overall appearance.

In the epoch of scientific and technological progress prosperity, with present medical skill, be not only required on the therapeutic effect and will get well, in the recovering aid work after the treatment, more require to have multiple benefiting, general especially with artificial limb as the instrument of recovering aid, and technological progress rapidly, can keep outside the valuable life of wounded body, another kind of auxiliaring effect is provided again, for example, concerning the people with disability who lacks lower limb, very sad within, add that again the walking aspect very under the serious blow such as inconvenience, often makes people with disability thereby general normal person lose more wider employment at low wages, the recreation chance, even fear in the face of the people on the outside because of incomplete limbs.The installing artificial limb can not only increase the convenience of people with disability's action, and can remedy the dress of overall appearance U.S. and clothing and go up more convenient (generally the trousers sold of market all are the both legs trousers), so artificial limb has become a kind of instrument that remedies of very important body and mind defective.And with regard to the whole artificial limb of present employed shank, this artificial limb includes many positions, for example artificial limb thigh, artificial limb knee-joint are partly, the below is connected with shank and ankle, sole artificial limb partly etc., and up to the present, shank artificial limb major part is to be used for other weight partly of body support, all must make with metal, so not only outward appearance is very not attractive in appearance, and the artificial limb made of metal material is exposed to corrosion phenomenas such as oxidation, water erosion takes place in the atmosphere easily, thereby the service life of the artificial limb that detracted.

Existing artificial limb is arranged with coating device 4 as shown in Figure 1 outside whole shank artificial limb 3, as covering and increasing usefulness attractive in appearance; Shank artificial limb 3 includes and is used for crooked knee joint part 31, so must be able to cooperate knee joint 31 bendings in the place of coating device 4 corresponding knee joints 31, coating device 4 is formed earlier body 42 backs (having no the legs curve shape) that are rectangle outside shank artificial limb 3 by the soft foaming body 41 of quality, be meant that through carefully and repeatedly cutting the body 43(that forms tool legs curve shape dotted line partly among the figure again), just finishing coating device 4 combines with the shank artificial limb again, though but the combination of this mode can provide shank artificial limb appearance attractive in appearance to the overcoat of artificial limb structure, but produced other serious problems, now stated as follows:

1. existing shank artificial limb except the body wt that supports the people when straight and upright, also need provide bending effect, so that in the use more near people's limbs, and more can convenient people with disability's walking, and remedies the open defect of incomplete limbs; Though but the coating device that the foaming body of soft quality is made can reach cooperation shank prosthetic walking, provide the knee joint place flexible effect, but because foaming body is that soft material is made, so the hole of the tissue of whole body is bigger, moisture content is penetrated in the foaming body hole and moisture content is held, so not only increased the weight of artificial limb, to the people with disability of script with regard to the slow inconvenience of action, more inconvenient in the use, and the overcoat of foam material is because moist and mouldy easily, antibacterial derives, with the passing of time the easier stink that sheds, even easily make and be encapsulated in the intravital metal artificial limb of cover and produce corrosion phenomena, the effect of artificial limb bending influenced greatly.

2. seeped water and the artificial limb of corrosion takes place, it is the most serious that especially metal knee joint is partly located, when walking, whole shank is after knee joint becomes angle of bend, can't stretch rapidly, to the people with disability just is very easy to thereby topples over regard to taking action slowly originally, accident meets accident.

3. artificial limb is a kind of aid in the action, original just can't compare with the motility of each limbs of normal person, especially concerning the knee joint of shank, not only to have supporting role, for the more necessary auxiliaring effect of people with disability with flexible bending, so, the device of prosthetic jacket, beautify the shank appearance except providing, also must pay attention to crooked and impermeable effect simultaneously.

Therefore, main purpose of the present utility model provides a kind of overcoat of artificial limb, by by pars contractilis and the body made by the harder foaming body of quality, so that have more safety when reality is used.

For reaching above-mentioned purpose, the prosthetic jacket that the utility model proposes is to coat coating device outside artificial limb, and coating device is made by the little foaming body of hole, is provided with pars contractilis in the corresponding kneed part of coating device; Also say so, the utility model proposes a kind of prosthetic jacket, this prosthetic jacket comprises artificial limb, connects the coating device of joint of artificial limb, it is characterized in that: the described coating device of being made by the little foaming body of hole is provided with pars contractilis corresponding to the place in described joint;

Described pars contractilis is network structure.

This prosthetic jacket device, not only waterproof, and the bending of the convenient artificial limb knee of energy, the bulk shape that increases artificial limb is attractive in appearance.

Now enumerate preferred embodiment and conjunction with figs., be described in detail as follows:

Fig. 1 is the axonometric chart of existing prosthetic jacket;

Fig. 2 is the axonometric chart of the prosthetic jacket that the utility model proposes;

Fig. 3 is the use sketch map of the prosthetic jacket that the utility model proposes;

Fig. 4 is the enlarged diagram of the pars contractilis of described prosthetic jacket;

Fig. 5 is that the prosthetic jacket that the utility model proposes is dressed the axonometric chart of going up colour of skin panty hose.

At first, see also shown in Figure 2ly, this figure is the axonometric chart of the prosthetic jacket that the utility model proposes; Artificial limb 10 is the artificial limb of a shank in the present embodiment, this shank artificial limb 10 comprises the artificial limb thigh, connects the artificial limb knee-joint part 11 of artificial limb thigh, (non-principal character person are not numbered) such as artificial limb knee-joint part 11 connection shanks and ankle, sole artificial limb parts, because the shank artificial limb is in order to other weight partly of body support, so must make it firmer with the metal material manufacturing.The shank artificial limb 10 outer one-body molded coating devices 20 that have, coating device 20 has had legs curve when molding, coating device 20 is made by the harder foaming body 21 of quality, so that whole body organize hole tiny, the tissue of body is closely, be difficult for infiltration moisture content, place in the knee joint 11 of body 20 corresponding shank artificial limbs 10 is provided with pars contractilis 22, pars contractilis 22 is formed with a plurality of mesh 221 on body 20, mesh 221 assumes diamond in shape, and be vertically to arrange, the magnitude range that pars contractilis 22 is provided with in knee joint 11 the place aheads of shank artificial limb 10 is similar with the magnitude range that is positioned at the setting of knee joint 11 rears, and that the scope that is provided with in shank artificial limb 10 both sides is provided with scope than knee joint 11 forward-and-rearwards is little.

See also Fig. 3 and shown in Figure 4, the knee joint bending that pars contractilis 22 can make shank artificial limb 10 freely, the diamond-shaped meshes 221 of pars contractilis 22 is understood dilatating and deformables (according to the angle of bend difference, then mesh dilatating and deformable size also has difference), and forms the pars contractilis of similar woven mesh.So by the body 20 that above-mentioned structure is formed, the bulk shape that can increase the shank artificial limb is attractive in appearance, and because body tissue tight property, not only can reach good waterproof effect, simultaneously bending that again can convenient artificial limb knee.

As shown in Figure 5,, look round still true to naturely inadequately eventually,, so just have more and beautify effect so can dress colour of skin trousers again in that cover is external though the prosthetic jacket device made of foaming can the colour of skin be a mass-tone.
