Description
Technical field
The utility model relates to ankle protector, especially a kind of parachutist's parachute jumping ankle-joint protective device.
Background technique
Parachutist's parachuting injury is the very high military activity of rate of causing injury.In the world according to U.S. army's preventive medicine center tune
Look into display: any stage in parachute jumping process, damage 7.5% of disembarking, parachuting damage can occur for parachutist's parachuting injury
6.3%, landing injury 86.2%.Epidemiological survey of the country to 7230 parachutist soldiers, as the result is shown umbrella instruction and parachute jumping
When primary damage location be ankle-joint, and parachute jumping be apparently higher than umbrella instruction when damage.Practical parachute jumping is compared with when umbrella is instructed, ankle-joint
The rate of injury is in first, hence it is evident that the damage location increased is ankle-joint, stern and hand.
Sprained ankle is high-incidence (32.8%) as the result is shown for epidemiological survey of this seminar to 397 parachutists, right
Find that the protective effect of ankle-joint protective device is especially pronounced when the analysis of Influential Factors of sprained ankle.Parachutist, China uses
Half-squat landing (half-squat parachute landing, HSPL), the rollover roll-type used with majority state paratrooper
Land (parachute landing fall, PLF) posture is different, and HSPL must keep the essential of exercise of " three tight one is flat ", i.e. bilateral
Knee, ankle, 3 points of tiptoe be in close up state always, lower limb muscles remain retracted state during jump is fallen, bilateral foot when landing
The palm is parallel to ground (forefoot is avoided the plantar flexion movement for visiting ground occur).If posture main points are made mistakes, since Calf muscle is in tight
The state opened, leads to sprained ankle, the followed by damage of knee joint, backbone first.Further, since land moment be accompanied by compared with
High landing velocity and acceleration, and usually landing ground out-of-flatness or with a varied topography, be easy to cause ankle-joint varus.
Ankle guard can reduce by 69% sprained ankle, and for the crowd for wound of haveing been friends in the past, it is possible to reduce 71% damage.Ankle
Joint protecting device protective performance depends not only on its material, structure and application method etc., it is often more important that it is to ankle-joint
Biomethanics damage mechanisms protective effect.
Research find the average varus of ankle-joint and dorsiflexion angular speed it is more big be easy to cause ankle-joint in coronal-plane and
Unstability in sagittal plane, elastic ankle guard and semi-rigid ankle guard can significantly reduce the damage ratio of ankle-joint, but semi-rigid ankle guard has
The interior activity of turning up of more significant protective effect, especially limitation ankle-joint.
Find that ankle joint bandage and ankle guard can substantially reduce the varus of ankle-joint, turn up, plantar flexion and dorsiflexion angle in research
Displacement.
Three categories are broadly divided into existing ankle-joint Protection Product:
Fixed sleeve type ankle guard, bandage wound form ankle guard and is inserted in bandage type ankle guard.Existing parachutist's ankle in the world
Joint protecting device is divided into bladder-type, composite panel of plastic material type such as the military external ankle guard that Aircast and DjOrhto company develops
Or foam type ankle-joint protective device, it can be effectively reduced the damage of ankle-joint, but its structure is complex, wearing is uncomfortable, ankle
Joint injury also happens occasionally.
The existing ankle-joint protective device in China can be divided into external, built-in and three kinds of double-purpose type inside and outside, external
Ankle-joint protective device be generally rigidity, be made of the polythene material of hard, structure bulky, wearing be inconvenient, comfort level
Difference；Built-in ankle-joint protective device is generally the preferable sporting article of elasticity, such as wound form bandage, patch are pricked, but its
Not having prevents the ankle-joint excessively inside and outside safeguard function turned over；Inside and outside double-purpose type ankle-joint protective device is rare on the market at present,
Have no that specialised literature reports it.Knapik etc. has recorded parachutist student and dresses ankle guard parachute jumping 33,461 times and protect without ankle guard
As a result lower parachute jumping 69,323 times is 1.83-2.0 times for dressing ankle guard without the damage ratio parachuted in the case of ankle-joint protection.
Utility model content

Specific embodiment
With reference to the accompanying drawings of the specification and specific embodiment makees further specifically the technical solution of the utility model
It is bright.
As shown in FIG. 1 to 3, the utility model includes ankle and foot 1, heel portion 2 and dorsal portion 3, and three is connected as one
A entirety, using the moderate pearl of elasticity cotton cloth are made, and have extraordinary gas permeability and penetrability.Pearl ground cotton cloth surface
It is poroid in dredging, it is similar to honeycomb, it is more more ventilative than common looped fabric, dry and comfortable and more resistant to washing.Pearl cotton cloth it is soft, absorbing sweat and
And it is not easy to deform, good color fastness.
Has spring on the inside of ankle and foot, the tensile strength of spring is 1800MPa, 28 times/360 ° of torsional strength, is extended
Rate 3%, the utility model ankle and foot inside have at least one spring, and ankle and foot is equipped with the pocket for grafting spring
Portion can change the quantity of institute's grafting spring according to demand, to adjust the support force size of entocondyle support.
At least one bar shaped pocket is sewed on the outside of ankle and foot, each bar shaped pocket interpolation connects the bar shaped support
Part, the preferred aluminum alloy bar of bar shaped supporting element described in the present embodiment (tensile strength >=370MPa, offset yield strength σ 0.2
(MPa): >=215, elongation δ 5 (%): >=12), and length × width x thickness=15cm × 1.2cm × 0.2cm, aluminum alloy bar inside
It is surrounded by foam cotton face fabric (100% ethylene-vinyl acetate copolymer), reduces the friction between external malleolus and CPAB, protect external malleolus skin
Skin.Outside reinforces that ankle-joint can be generated " waling " effect in ankle guard, can also limit ankle-joint to a certain extent in sagittal plain
Movement is turned over inside and outside on the movement on Coronal, especially Coronal.
Further, as a preferred embodiment of technical solutions of the utility model, ankle and foot is viscous by one, top
Band and the adhesive tape of instep upper limb two intersections, which pressurize, to be fixed, and user's adjustable-tightness degree wraps up whole device firmly
