Abstract
The present invention relates to have the skeleton-type artificial leg of simulation skin.The present invention coats one deck latex film as simulation skin outside the polyurethane foams layer of skeleton-type artificial leg, thereby makes the soft froth bed of artificial leg have higher-strength and elasticity; Waterproof; Make the artificial limb anticorrosion, the life-span is long.
Description
The present invention relates to the pseudocolloid field.
The endoskeletal prosthesis product that grows up in the world in recent years comprises metal joint, support bar and decorates and use soft overcoat adding one deck for increasing aesthetic feeling, perhaps adds nylon stocking cover.This low as soft outer high resilience flexible foams intensity of applying mechanically, sensitive for damages; Suction, therefore, the rainy day can not go out, and internals corrosion-vulnerable and reduce service life; Easily the absorption dust can't clean again, thereby influence attractive in appearance.
The object of the invention is: a kind of skeleton-type artificial leg with simulation skin is provided, by stump socket, the soft froth bed of the artificial leg that joint of artificial limb, supporting linkage, false foot and the soft froth bed of high resiliency are formed coats one deck intensity height, waterproof, the strong non-damageable skin of emulation outward at this.
The objective of the invention is to reach like this: outside the polyurethane foam of skeleton-type artificial leg, coat one deck latex top layer as simulation skin, reached thereby the object of the invention is finished.
Below artificial leg of the present invention is elaborated:
Material as endoskeletal prosthesis top layer skin is higher except that desired strength, can waterproof, not fragile; also should have higher elasticity, can be one with high resiliency ammonia ester foamed plastic close adhesion, thereby protection artificial limb internals is not corroded; characteristics such as the making raw material is easy to get, and manufacturing process is simple.
What can adapt to that above-mentioned hundred million corium skins require is latex, the relative density of latex be 0.90-0.95 be that the density of it and water is close, can make water solublity preparation liquid by any mixed with water, and without other chemical solvent, thereby cost is low, pollution-free, easy spary film forming; It also not with polyurethane foams generation chemical reaction as basic material, therefore, do not influence the physical and chemical performance of base material; The stable chemical performance of latex itself; Applicable temperature is-50-100 ℃; Nontoxic, free from environmental pollution; Adhesion strength is strong, can become an integral body with combining closely as the polyurethane foams of base material; Made membranous ground is soft, durable in use, and light weight can improve the intensity and the fatigue performance of base material, again can waterproof.Therefore, when latex film was wrapped in outside the polyurethane foams layer of artificial limb, it can satisfy the specification requirement of endoskeletal prosthesis to its clad, in addition, can also adjust color according to patient skin, thereby can increase aesthetic feeling, relaxed people with disability's psychological burden.
The method for making of skeleton-type artificial leg with simulation skin is as follows:
Preparation latex is prepared liquid earlier, containing 50(weight) add 1(weight in the latex aqueous solution of %) conventional vulcanizing agent about %, 1.5(weight) the conventional promoter about % and a small amount of conventional dispersant and stabilizing agent, stir through fully mixing, make latex preparation liquid, by stump socket, joint of artificial limb, supporting linkage, outside the polyurethane foams layer of the artificial leg that false foot and polyurethane foams layer are made, brush or spraying one deck thin layer with above-mentioned latex preparation liquid, then with 60-70 ℃ of warm wind baking, make its drying, make the artificial limb that has fixed artificial limb skin, also can outside polyurethane foams, put the high resiliency nylon sock, the above-mentioned latex preparation of reuse liquid is brushed or spraying one deck thin layer, it is dry to blow oven dry, make the artificial limb that has peelable formula artificial limb skin, the thickness of the latex film of more than brushing or spraying is not more than 0.5 millimeter; Breaking strength is more than or equal to 200 kg/cm; Percentage elongation is pulled apart deformation rate less than 12% greater than 700%, and aging coefficient is 0.8.
The advantage of skeleton-type artificial leg that the present invention has simulation skin is as follows:
1) owing to have the artificial limb skin of latex, increased the intensity of polyurethane foams layer, thereby improved the service life of artificial limb;
2) because the coating of simulation skin has increased the washability to the polyurethane foams kind;
3) water resistance is arranged, patient mixes artificial limb of the present invention, but in the rainy day also outdoor activity, even just in case slip and fall into the water, also can not cause damage to artificial limb;
4) its appearance is half optical coating, and light is soft, and emulation is strong, increases aesthetic feeling, relaxes the outpatients mental state burden;
5) higher elasticity is arranged, do not influence artificial limb knee bends and walking function;
6) color of simulation skin can be prepared by patient's colour of skin;
7) prevent that the artificial limb internals from being corroded, reduce maintenance, improve artificial limb service life;
8) this simulation skin is made simply, and technology is easy to grasp;
9) the latex raw material sources are abundant, and are inexpensive, nontoxic, nonflammable, are convenient to transportation and preserve;
10) the made artificial leg that has peelable simulation skin, its simulation skin also can take off at any time, so that positions such as the ankle of breakage, knee joint are keeped in repair;
11) can clean at any time.
Claims (2)
1, skeleton-type artificial leg, have stump socket, joint of artificial limb, supporting linkage, false foot and polyurethane foams layer, it is characterized in that: on the smooth surface of said polyurethane foams layer, brush or spray one deck by the conventional promoter of conventional vulcanizing agent, 1.5 (weight) % that adds 1 (weight) % in the latex aqueous solution that contains 50 (weight) % and the emulsion preparation liquid of a small amount of conventional dispersant and stabilizing agent, under 60--70 ℃, blow the latex film simulation skin that the dry back of oven dry forms.
2, according to the said skeleton-type artificial leg of claim 1, it is characterized in that: at said polyurethane foams layer overcoat last layer nylon stocking, on these silk stocking, brush again or the said latex preparation of spraying one deck liquid, under 60-70 ℃, blow the latex film simulation skin that the dry back of oven dry forms.
