Description

Knee pad

Technical Field

The utility model relates to a sports protective equipment and medical treatment assist the utensil technical field, especially relate to a knee-pad.

Background

Many middle-aged and elderly patients suffer from knee joint pain and limited function due to knee joint hyperosteogeny, meniscus injury, and decreased muscle and ligament strength. The knee pad in the prior art only has the function of keeping warm, and cannot relieve or improve the further injury of a patient with injury at the knee joint to the injury position in the walking process.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned problem among the prior art, the utility model provides a knee-pad has solved the knee-pad among the prior art and can't alleviate or improve the problem of walking to the further injury of the knee joint that has the damage.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows:

the knee pad comprises two identical knee pads and a plurality of binding bands detachably fixed outside the two knee pads, each knee pad comprises an elastic belt, an upper main support arm and a lower main support arm which are fixed on the elastic belt and hinged with each other, a torsion spring is arranged at the hinged position of the upper main support arm and the lower main support arm, a plurality of branch arms are connected to the upper main support arm and the lower main support arm in a pivot mode, the branch arms are made of soft iron and are fixed on the elastic belt.

Furthermore, the upper main support arm and the lower main support arm are fixed at the outer side of the elastic belt and near the edge; one end of the branch arm is pivoted with the upper main support arm or the lower main support arm, and the other end of the branch arm extends to the other edge opposite to the upper main support arm or the lower main support arm. Make branch arm all be located the homonymy, when twining the elastic webbing at patient's shank, the branch arm of soft iron material can be crooked along with the radian of patient's shank, and the branch arm of homonymy bending is the same at the main tributary arm under dragging the atress direction, can drag the elastic webbing and remove to the homonymy, makes the patient adjust along the change that the in-process elastic webbing of walking can follow the shank, makes the patient feel more comfortable.

Furthermore, the two sides of the elastic band are respectively fixed with a fiber strip and a wool-stabbing strip, and the fiber strip and the wool-stabbing strip form a sticky buckle band which can be mutually bonded. The two knee protection belts are conveniently connected into a complete knee protection sleeve, and the fastening belts are reliably and quickly connected; and the width of the fiber strip or the barbed strip is widened to increase the adjusting range of the width of the knee pad strip so as to adapt to patients with different leg thicknesses.

Furthermore, the width of the upper end of the elastic band is larger than that of the lower end of the elastic band, and silica gel layers are fixed on the inner sides of the upper end and the lower end of the elastic band. The silica gel layer can be sticky with shank skin to the position of fixed knee-pad both ends at the shank avoids the knee-pad landing, improves the travelling comfort and the convenience of dressing.

Furthermore, the upper main support arm and the lower main support arm are located on the same vertical plane, an L-shaped plate is integrally formed at the top end of the lower main support arm, the L-shaped plate and a connecting plate integrally formed on the upper main support arm are oppositely arranged, and two ends of a torsion spring are respectively fixed on the L-shaped plate and the connecting plate. The top end of the lower main support arm extends to the opposite side of the upper main support arm through the L-shaped plate to install the torsion spring, so that the upper main support arm and the lower main support arm are positioned on the same vertical plane, the upper main support arm and the lower main support arm are ensured to be in full contact with the elastic band and the legs of a patient, and the consistency of the upper main support arm and the lower main support arm with the legs is better.

Furthermore, a round shaft is fixed on the L-shaped plate, and the round shaft penetrates through the torsion spring and the connecting plate in sequence with gaps and then is detachably connected to the end nut. The upper main supporting arm and the lower main supporting arm are hinged through the round shaft, and the torsion spring is installed and supported.

Further, the branch arms are densely distributed along the length direction of the upper main support arm or the lower main support arm. The more dense the branch arm, the bigger the contact area with the elastic band, and main support arm is in the motion process, and the uniformity that the elastic band followed main support arm motion is higher, and the patient is the more not involved sense in the use, and the travelling comfort is higher.

Furthermore, a plurality of rows of elastic bands which are arranged at intervals and are used for the binding bands to pass through are fixed on the outer side of the elastic band. The position of the bandage is fixed through the elastic band, so that the bandage is prevented from slipping, and the firmness of knee pad fixation is improved.

Further, the end of the binding band is adjustably connected through a buckle or a magic tape. The bandage is simple and efficient to connect and detach, and can be adjusted according to the thicknesses of legs of different patients.

The utility model has the advantages that: the upper main branch arm and the lower main branch arm fixed in the knee protection belt are respectively clung to the thigh above the knee joint and the lower shank below the knee joint through elastic belts, and the torsion springs arranged at the hinged parts of the upper main branch arm and the lower main branch arm at the knee joint play the roles of buffering and generating elasticity in the knee bending/extending process of a patient, so that the shearing force of the bent knee joint on the knee joint can be reduced through buffering, and the damage to the meniscus is reduced; the control of the centrifugal contraction/centripetal contraction force of the quadriceps femoris muscle in the process of bending/extending the knee is improved through the elastic force of the torsion spring, thereby helping the patient to relieve pain and improving the function limitation.

The knee pad in this scheme is formed around patient's shank concatenation by two the same knee pads area for the opposite side of patient's knee joint is by a pair of through torsional spring articulated last main tributary arm and the auxiliary action of main tributary arm down, can improve walking in-process auxiliary action's equilibrium and travelling comfort. The binding band can improve the combination tightness of the knee protecting band and the leg of the patient.
