Abstract

The utility model relates to a horseshoe-shaped protective pad for preventing old people's fracture of hip, particularly a hip protective pad in the shape of reverse U. The utility model is contacted and fixed with a hip of human body via elastic bands and nylon fasteners respectively, wherein, the elastic bands are arranged on both sides of the protective pad; the nylon fasteners are arranged on both sides of the elastic bands. The utility model is suitable for preventing the bone fracture that the framework of hip bones is fractured because of the stress concentration generated in a sudden overload. The utility model can effectively buffer the stress load of the hip acted by an outside force, and can prevent the occurrence of the fracture of the framework of hip bones. At the moment of a tumble, the U-shaped protective pad effectively buffers the concentration of the stress load on the hip, and immediately generates a response effect to resist and buffer the load; the probability of the occurrence of the fracture is reduced. The utility model has the advantages of simple structure and comfortable wear.

Description

Hip protector

This utility model relates to a kind of shape of a hoof protective pad that is used to prevent old people's Hip Fracture, specifically is a kind of inverted U Hip protector.

By the fracture fracture of femoral neck that osteoporosis caused, intertrochanteric fracture of the femur etc. are old people's's (particularly patients with osteoporosis) height morbidity.Cure fully after the fracture and the difficulty of rehabilitation very big, and become gerontal patient's a great society problem.

According to statistics, the old people of China's over-65s in 1999 surpasses 1.2 hundred million, 10% (being higher than global average level 9.8%) that accounts for country's total population.That wherein suffers from degrees of osteoporotic disease is about 56%, and the overwhelming majority is the female patient of amenorrhea, they be this type of fracture send out colony well, and therefore directly have influence on health.

And today of constantly improving along with life of elderly person quality and quality mind, outstanding behaviours is: the number of participating in outdoor exercise increases year by year; The old people of out on tours regularly more gains momentum.Only these two, promptly, then strengthen the damage of limbs and the probability of fracture doing comparatively violent (over loading motion) and moving when having felt fatigue.With the growth at age, old people's gait changes, and bends the hip scope and reduces, the foot sole of the foot is crooked to be reduced, the heel of limbs and the angle between the ground reduce thereupon, and the damage ratio of limbs strengthens, its mainly show as clinical common fracture of femoral neck, waist injury, and ankle and foot sprain etc.

The clinical open reduction of taking, fixing operation treatment, and the function rehabilitation training of postoperative or the like, all are remedial treatment measures of taking at the fracture that has taken place, and after fracturing, the counter stress of hip joint framework-strain adapts to the limit and reduces, and the original strength and stiffness of bone reduce, though through surgical operation therapy, still have an appointment 34% patient is maimed or die from the generation of other complication in 1 year.

The purpose of this utility model is to provide a kind of confession used in everyday, particularly has the inverted U Hip protector of preventive effect.

The prevention mechanism of inverted U Hip protector is in order to the buffering old people, when falling accidentally, cause acts on the moment stress of hip, proximal femur from the counteracting force (acting on the active force on ground with respect to the joint) on ground, thereby decompose external force effectively and revolve the stress loading that is added on the bone, avoid and reduce the probability of generation fracture, really play the preventive effect before fracture takes place.

The exopathogenic factor condition that easily causes fracture is: with advancing age, old people's gait changes, the corresponding minimizing of the scope of application of joint of the lower extremity, by gait analysis to the normal person of human body height close (the range of age 20-75 years old), in the moment of heel contact, the two body in sagittal plane is a difference, and the old people then shows as: bend the hip scope and reduce; When the ankle sole of the foot was crooked, what limbs landed reduced with a ditch (heel-floor angle), and therefore, causing the probability of falling obviously increases.

The endogenous cause of ill condition that easily causes fracture is: senile osteoporosis is relevant with the pilosity of Hip Fracture, neck of femur inside is made of spongy bone, its inside and outside two bone trabecula system is used to adapt to the pressure that produces when the counteracting force of femoral head upper joint and opposing abductor shrink.The old people is because degenerative change (degenerativechange) appears in neck of femur, the cortical bone attenuation, the density of bone reduces, the part bone trabecula attenuates, fracture or when being absorbed, the original strength and stiffness of neck of femur reduce, so it can not bear the ability (this utmost carrying ability is 4 times of human body body weight) of nominal stress loading, very easily fracture.

The purpose of this utility model is achieved in that a kind of old people of being used for prevents the protective pad of Hip Fracture, this protective pad is made by elastic rubber material, monnolithic case is an inverted U, respectively through being located at the elastic cord at two ends, and the elastic cord two ends velcro contact with the hip of human body and fix.

Described inverted U protective pad two arms parallel to each other are beloid, and forearm is 25mm, and postbrachium is 35mm, and the radius of curvature of bottom is 40mm, and the distance between the arm of front and back is 70-80mm, and forward and backward brachium is 350-400mm.The section that described inverted U protective pad inwardly is provided with in order to damping is the groove of U type, and is provided with the vibration damping hole successively contacting fixed groove inboard with hip.Diameter in the inboard set vibration damping of forearm hole is 10mm, and the diameter in inboard set vibration damping hole is 10-15mm in the bottom, and the diameter in the inboard set vibration damping of postbrachium hole is 15mm.

Effect of the present utility model: can effectively cushion the stress loading that external force acts on hip, prevent the generation of hip skeleton framework fracture; U type protective pad is in falling moment, effectively cushions stress loading the concentrating of hip, the instant effect of replying that produces opposing and cushion load, the probability of the generation of avoiding fracturing; It is simple for structure, wears comfortable.

Description of drawings: 1 forearm, 2 bottoms, 3 postbrachiums, 4 elastic cords, 5 velcros, 6 damping grooves, 7 vibration damping holes, 8 inboards, 9 outsides.

Now in conjunction with the accompanying drawings structure of the present utility model and use are elaborated: as shown in the figure: this utility model can use for one-sided or bilateral, the inboard in set successively vibration damping hole contacts fixing with hip, the concentrating of hip, the specification of waist elastics is at 50mm * 800-1200mm with effective buffering stress loading; The specification of femur portion elastic cord is used with the old people who adapts to different height builds at 40mm * 500-700mm.
