Protector for preventing joints from moving quickly

Abstract

The invention discloses a protector for preventing joints from moving quickly, and belongs to the field of medical instruments for the orthopedics department. The protector comprises a near-end fixing part (4), a far-end fixing part (3), a myoelectricity control device and a connecting device, wherein the near-end fixing part (4) is fixed on a joint near-center end limb (1), the far-end fixing part (3) is fixed on a joint far-center end limb (2), and the connecting device is respectively connected with the near-end fixing part (4) and the far-end fixing part (3). The myoelectricity control device is used for sensing muscle signals corresponding to the joints and controlling the connecting device. When the joint is slowly bent and stretched, the near-end fixing part (4) and the far-end fixing part (3) do free relative movement; when the joint is suddenly and rapidly bent and stretched, the connecting device prevents relative movement between the near-end fixing part (4) and the far-end fixing part (3), and therefore the joint is prevented from being damaged.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to an appliance for protecting joints during joint rehabilitation. Background technique [0002] Human joints (including knee joints, elbow joints, etc.) are important organs of the human body, but because the joints can rotate, compared with other orthopedic diseases, the recovery process of joints is more difficult. Especially during the joint rehabilitation period, ensure a certain range of motion and move the joints slowly, which is conducive to the recovery of joint strength, but do not move suddenly and quickly to prevent damage to the joints. In reality, avoiding the above situations mainly depends on the patient's self-control. However, people often move their joints suddenly and violently when they are unintentional or in a state of sleep. Especially for children who have no self-control ability, this situation is more likely to occur, which will cause damage to t...

AI Technical Summary

Problems solved by technology

However, people often move their joints suddenly and violently when they are unintentional or in a state of sleep, especially for children who have no self-control ability, this situation is more likely to occur, which will cause damage to the joints

[0003]In the prior art, most of them avoid damage by limiting the range of motion of joints, such as the patent "splint for fixing joints" (publication number CN102858282B), this solution is applicable In the early stage of joint injury or postoperative, but not suitable for rehabilitation

In the rehabilitation period, in order to ensure a certain amount of activity, some patents also disclose the introduction of rehabilitation robot technology in training, such as "a kind of underactuated upper limb rehabilitation robot control system" (publication number is CN 106974795 A), so that not only the rehabilitation The therapist is freed from heavy rehabilitation training, and can also use different training methods and training intensities for different patients, but the system is complex and expensive, and it is not suitable for independent exercise during the rehabilitation period

[0004] To sum up, how to solve the self-exercise period during the rehabilitation period, which can not only allow the joints to move slowly, but also ensure that the violent activities will not cause damage to the joints, is open in the field of joint rehabilitation Not reported in the literature
