Adjustable hip joint training device capable of accurate feedback

Abstract

The invention provides an adjustable hip joint training device capable of accurate feedback. One end of a leg length matching mechanism is hinged to a sliding block; the sliding block moves on a sliding rail parallel to the connecting line of the left hip joint and the right hip joint of a human body, and an angular displacement sensor collects the rotating angle of the leg length matching mechanism at the hinged position; the other end of the leg length matching mechanism adjusts the length through a guide rail and is provided with a position locking mechanism; one end of a servo driving mechanism is hinged to a bed board, and the other end of the servo driving mechanism is hinged to the leg length matching mechanism; the servo driving mechanism is used for driving the leg length matchingmechanism to rotate; a leg bandage is used for fixing the thigh of a patient and installed at the other end of the leg length matching mechanism through a compensation guide rail; the compensation guide rail can move freely in the leg length direction; and a force sensor is installed between the leg bandage and the compensation guide rail to measure the force applied on the leg bandage by the patient. The hip joint training device is safe and reliable, adjustment and locking can be effectively conducted, and the hip joint training condition can be accurately fed back.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment, and relates to a hip joint training device. Background technique [0002] At present, rehabilitation medical equipment uses different hip joint training devices for lower limb rehabilitation training in the early stage of rehabilitation. However, the traditional training device cannot fully adapt to more people, especially when the patients are of different heights, the matching adjustment is less, and the sensor detection feedback is lacking. It is only a simple leg lifting and stepping training, which cannot accurately reflect the patient's leg movement angle and development. Strength. With the increasing demand in the rehabilitation medical market, some intelligent rehabilitation training devices have appeared on the market, but only rely on servo motors to monitor the patient's force and movement angle, and there is no sensor that directly monitors the patient's move...

Problems solved by technology

However, the traditional training device cannot fully adapt to more people, especially when the patients are of different heights, the matching adjustment is less, and the sensor detection feedback is lacking. It is only a simple leg lifting and stepping training, which cannot accurately reflect the patient's leg movement angle and development. Strength

With the increasing demand in the rehabilitation medical market, some intelligent rehabilitation training devices have appeared on the market, but only rely on servo motors to monitor the patient's force and movement angle, and there is no sensor that directly monitors the patient's movement angle and force. Through indirect conversion The patient's movement angle and force are calculated, and the device has no adjustment mechanism to more scientifically adapt to different groups of people, and it cannot achieve precise rehabilitation. Therefore, the hip joint training is designed to be safer, more reliable, effective, adjustable locking, and accurate feedback. device is necessary
