Description

Simple Knee Flexion Angle Measuring Device

Technical field:

The utility model relates to an angle measuring device, in particular to a simple knee joint flexion angle measuring device.

Background technique:

Injuries to lower extremity joints, such as: knee fracture, ligament injury, knee flexion contracture, acute soft tissue injury, patella fracture, dislocation, lateral instability of the knee joint, reflex knee, angle measurement is often used in the rehabilitation treatment process The angle measuring device measures the flexion angle of the affected limb to judge the rehabilitation of the affected limb. Most of the existing angle measuring devices are fixed with the brace. Because the structure of the brace is heavy and the straps are airtight, if the knee flexion angle is measured on the affected limb in the hot season, it will bring a lot of inconvenience to the patient.

Invention content:

Aiming at the problems existing in the above-mentioned prior art, the utility model provides a simple knee joint flexion angle measuring device. The angle measuring device has a simple structure and is easy to use, which is beneficial to the postoperative rehabilitation function exercise of patients undergoing knee joint surgery.

In order to achieve the above object, the technical solution adopted by the utility model is: a simple knee joint flexion angle measuring device, including a protractor, a protractor fixed arm arranged on the protractor, and a rotating arm used to indicate the angle, the protractor, the fixed The arm and the rotating arm are made of hard materials. The protractor is connected with the rotating arm through a rotating shaft. The rotating arm can rotate around the center of the protractor. Angle indication holes are arranged on the rotating arm. The fixed arm of the protractor and the rotating arm are respectively A pasting device is provided.

Further, the sticking device is a bag-shaped structure, which is respectively sleeved on the fixed arm and the rotating arm. The four corners of the sticking device are provided with fixing belt penetration holes, and one side of the sticking device is a sticky foam sticker.

Further, there are two angle indicating holes on the rotating arm, and the rotating arm is provided with a scale.

Further, the width of the fixed arm and the rotating arm is 4-5CM, and the length is 20-25CM.

Further, the protractor is a 180° semicircular protractor or a 360° circular protractor.

The simple knee joint flexion angle measuring device of the utility model is not only simple in structure and convenient to use, but also enables the patient to measure the flexion angle of the knee of the affected limb at any time during the rehabilitation process, so that the patient can grasp the recovery situation of himself without worrying about the progress of his own rehabilitation. It is beneficial to the rehabilitation of knee joint function after operation. The sticking device can stick repeatedly, the protractor, the fixed arm and the rotating arm are made of hard materials, the manufacturing cost is low, and it is suitable for application and popularization.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the right view of the utility model;

Fig. 3 is a schematic diagram of the structure of the fixing belt.

In the figure, 1. protractor, 2. fixed arm, 3. rotating arm, 4. rotating shaft, 5. angle indicating hole, 6. pasting device, 7. fixing belt piercing hole, 8. fixing belt.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Fig. 1, Fig. 2, Fig. 3, a kind of simple knee joint flexion angle measurer comprises a protractor 1, a protractor fixed arm 2 arranged on the protractor, and a rotating arm 3 used to indicate an angle, the protractor 1 1. The fixed arm 2 and the rotating arm 3 are made of hard material, which can be made of plastic material. The protractor 1 and the rotating arm 3 are connected through the rotating shaft 4. The rotating shaft 4 can use screws or rivets, and the rotating arm 3 can be wound around the protractor 1. The rotating arm 3 is provided with an angle indication hole 5, and the fixed arm 2 and the rotating arm 3 of the protractor are respectively provided with a pasting device 6.

Further, the pasting device 6 is a bag-shaped structure, which is respectively sleeved on the fixed arm 2 and the rotating arm 3. The four corners of the pasting device 6 are provided with fixing belt penetration holes 7, and one side of the pasting device 6 is a Adhesive foam stickers. Since the sticking device 6 is sleeved on the fixed arm 2 or the rotating arm 3, when the sticking device 6 is used repeatedly and the stickiness is not enough, the sticking device 6 can be replaced, which is convenient for continued use. As shown in Figure 3, it is also possible to use the fixing belt 8 to pass through the fixing belt penetration hole 7 on the sticking device 6 to be bound on the patient's leg, which is more firm. Generally speaking, the fixing belt 8 uses an elastic band, and its width is 3CM, and the length It is about 35CM.

Simultaneously, in order to be more convenient to use, also can be set to described pasting device 6 as single-layer structure, double-sided all has stickiness, one side is pasted with fixed arm 2 and rotating arm 3, and the other side can be pasted directly on patient's leg.

Further, the number of angle indicating holes on the rotating arm 3 is set to two, the distance between the two holes is slightly smaller than the diameter of the protractor, and the rotating arm 3 is provided with scales, so that the measurement is more accurate.

Further, the width of the fixed arm 2 and the rotating arm 3 is 4-5CM, and the length is 20-25CM, which is designed according to the human body of ordinary height.

Further, the protractor 1 is a 180° semicircular protractor or a 360° circular protractor.

During use, the fixed arm 2 is pasted on the thigh of the affected limb, the rotating arm 3 is pasted on the lower leg of the affected limb, and the fixing band 8 is used to pass through the fixing band 8 on the sticking device 6 to penetrate the hole 7 and be bound on the patient's leg, and the patient keeps The thigh does not move, and the knee joint is bent. Through the measuring device, the patient can measure the flexion angle of the knee of the affected limb at any time during the rehabilitation process, so that he can grasp his own recovery situation without worrying about his own recovery progress. The structure is simple, the material is light, the manufacturing cost is low, and it is suitable for application and popularization.
