Detailed Description

In order to make the utility model more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model provides a device for elbow joint activity and muscle strength training, which is used for elbow joint resistance strength training and joint activity passive static drafting training and comprises a forearm plate 1 and an upper arm plate 3, wherein the forearm plate 1 is rotatably connected with the upper arm plate 3, and the forearm plate 1 is connected with the upper arm plate 3 through a rotating shaft, so that one of the forearm plate 1 and the upper arm plate 3 can rotate around the other. The axes of the forearm plate 1, the upper arm plate 3 and the rotating shaft are respectively provided with a bandage for fixing the forearm, the upper arm and the elbow joint of the patient. The inner side surface of the forearm plate 1 is connected with the inner side surface of the upper arm plate 3 through a detachable inner side resistance belt 2 and is used for actively resisting and stretching the elbow joint; the dorsal side of the forearm plate 1 is connected to the dorsal side of the upper arm plate 3 by a detachable dorsal resistance band 4 giving a certain resistance to flexion of the elbow joint. Two back-side resistance belts 4 are arranged on the forearm plate 1 and the upper arm plate 3, and the two back-side resistance belts 4 are arranged on two sides of the back sides of the forearm plate and the upper arm plate; the minimum distance between the dorsal resistance bands 4 on both sides can accommodate a patient with a swollen upper limb after surgery. The forearm plate 1 and the upper arm plate 3 are provided with two inner side resistance belts 2, and the two inner side resistance belts 2 are respectively arranged on two sides of the inner side surfaces of the forearm plate and the upper arm plate; the minimum distance between the medial resistance bands 2 on both sides can accommodate a patient with a swollen upper limb after surgery. Forearm board 1 and upper arm board 3 all are slight concave type, and the medial surface or the lateral surface of forearm board 1 and upper arm board 3 are equipped with the recess promptly, and the transverse diameter both ends distance 15 centimetres of recess can hold the upper limbs of patient's postoperative swelling.
