AI Technical Summary
Existing exercise equipment cannot effectively exercise multiple joints in a lying position, and most of the equipment requires patients to stand or sit, resulting in low exercise efficiency.
An auxiliary device was designed, comprising a support frame, a reclining board, a lower limb flexion-extension component, and an upper limb flexion-extension component. It utilizes linkages, elastic bands, and rollers to achieve multi-joint flexion-extension exercises. The lower limb flexion-extension component drives the foot pedal to move back and forth, while the upper limb flexion-extension component drives the arm movement, thus achieving simultaneous exercise of multiple joints.
It enables simultaneous exercise of multiple joints in a lying position, improving exercise efficiency, especially for the recovery of activity in the ankle, knee, hip, wrist, elbow, and shoulder joints.

BRIEF DESCRIPTION OF DRAWINGS
[0012] Figure 1 It is a structure schematic view of the limb joint function exercise auxiliary device of the embodiment.
[0013] Figure 2 It is a structure schematic view of the lower limb flexion and extension assembly of the embodiment. DETAILED DESCRIPTION
[0014] The specific implementation of the utility model will be further described below in combination with the drawings.
[0015] As shown in the drawings, Figure 1 The limb joint function exercise auxiliary device of the embodiment is mainly used for assisting the flexion and extension activities of lower limb joints and upper limb joints, and is especially suitable for patients who are not suitable for standing position activities. The auxiliary device comprises a support frame 1, a lying board 2, a lower limb flexion and extension assembly and two upper limb flexion and extension assemblies; the support frame 1 is the support base of the whole device, and the length thereof is about twice the length of the lying board 2; the lying board 2 is fixedly installed on the support frame 1, is a planar plate body, and occupies about half the length of the support frame 1. When exercising, the patient needs to lie on the lying board 2. In order to improve the comfort, an isolation soft pad can be laid on the lying board 2; the lower limb flexion and extension assembly is movably installed on the support frame 1, is located on the other half of the support frame 1 which is not the position of the lying board 2, and has an activity stroke of about half the length of the support frame 1, and is mainly used for lower limb flexion and extension activities; and the two upper limb flexion and extension assemblies are movably installed on the two sides of the lying board 2, and are mainly used for upper limb flexion and extension activities.
[0016] In combination with Figure 2 , the lower limb flexion and extension assembly comprises a connecting rod 41, an elastic band 42, two rollers 43 and two guide rail kits. Among them,
[0017] The connecting rod 41 is a smooth cylindrical rod body, which is arranged on the support frame 1 and has two foot pedals 40 arranged thereon, the two foot pedals 40 can rotate around the connecting rod 41, and the foot pedals 40 are provided with straps, which can be used to tighten and prevent the feet from falling off when the patient puts his feet on the foot pedals 40.
[0018] The elastic band 42 connects the connecting rod 41 and the lying plate 2, when the connecting rod 41 moves away from the lying plate 2, the elastic band 42 is elongated and provides resistance to the movement of the connecting rod 41, which can provide certain resistance when doing lower limb flexion and extension, so that the patient can perform a certain amount of resistance exercise and exercise the muscles.
[0019] The two rollers 43 are respectively sleeved on the two ends of the connecting rod 41 and are rotatably arranged on the support frame 1, and the simplest circular bearing is used as the roller 43 in the embodiment. The two rollers 43 support the entire lower limb flexion and extension assembly.
[0020] The two guide rail assemblies are respectively arranged at the two ends of the connecting rod, and each guide rail assembly comprises a sleeve 44, a linear bearing 45 and a light rod 46. The sleeve 44 is fixedly sleeved on the connecting rod 41 and mainly serves to connect and stabilize, the linear bearing 45 is fixedly arranged below the sleeve 44 and mainly serves to slide. The light rod 46 is fixedly connected between the support frame 1 and the lying plate 2, should be arranged horizontally, and is inserted into the linear bearing 45 and can freely slide in the linear bearing 45, mainly serving as a guide rail. The two guide rail assemblies are mainly used to define the movement track of the lower limb flexion and extension assembly, so as to avoid the deviation of the lower limb flexion and extension assembly when the left and right feet exert force unevenly.
[0021] The lying plate 2 is provided with two sliding grooves 51 on the two sides, and the two upper limb flexion and extension assemblies are movably arranged in the two sliding grooves 51 of the lying plate 2. Each upper limb flexion and extension assembly comprises a sliding block 52, a handle 53 and a push rod 54, the sliding block 52 and the push rod 54 are located in the sliding groove 51, the sliding block 52 is fixedly sleeved on the push rod 54, the handle 53 is fixedly connected to the sliding block 52, and the push rod 54 extends out of the lying plate 2 and is fixedly connected with the sleeve 44 of the lower limb flexion and extension assembly. The patient holds the handle 53 with both hands, which can drive the sliding block 52 to move through the push rod 54, and the sliding block 52 drives the patient's hands to flex and extend through the handle 53. Of course, if the patient's upper limbs are relatively strong, the push rod 54 can also be used to promote the movement of the connecting rod 41.
[0022] Working principle: first make the patient lie on the lying plate 2, and make both feet tread on two foot pedals 40, and the belt fixes both feet, when the lower limbs flex and stretch, the lower limb flex and stretch assembly moves forward and backward, the elastic band provides resistance, and exercises the ankle joint, knee joint and hip joint of the patient. At the same time, the patient's hands can also hold the handle 53, and through the push rod 54, the upper and lower limb flex and stretch assemblies can be linked, so as to drive the hands to move, and exercise the wrist joint, elbow joint and shoulder joint of the patient.
