Technical field

The utility model relates to the technical field of medical rehabilitation training equipment, and in particular to an automatic exerciser for foot function of bone traction patients.

Background technique

When the lower limbs of the human body are injured and local fractures occur, long-term bed rest is often required. In severe cases, bone traction treatment is required. Stainless steel Kirschner wires are used to directly traction the bones, so that the fractures and dislocations can be effectively reduced and fixed, such as As shown in Figure 1. Since the lower limbs are in a fixed state, the patient is unwilling or unable to perform corresponding foot movements, such as dorsiflexion and plantar flexion of the foot, under the influence of activities that can easily cause great pain. When the foot is not moved for a long time or does not move properly, it is easy to cause foot muscle atrophy, foot drop and other symptoms, leading to a decrease in foot function, which is not conducive to the patient's recovery. Therefore, in order to ensure that the feet of bedridden patients can get enough exercise, clinical nurses often need to assist the patients in foot exercises.

The length directions of the side plate 231 of the linkage member 23, the swing rod 31 and the foot plate 4 are consistent.

The bracket 32 includes a horizontal bar 321 with one end in the length direction fixed on the side wall of the lower limb pad 1 and a vertical bar 322 disposed vertically and fixed on the top surface of the end of the cross bar 321 away from the lower limb pad 1 . There are two horizontal bars 321 and two vertical bars 322 located on both sides of the swing rod 31 . In this embodiment, the swing rod 31 is located in the middle of the opposite vertical rod 322 .

The upper part of the swing rod 31 is provided with a through hole opposite to the vertical rods 322 on both sides. A rotating shaft 33 is provided in the through hole, and the rotating shaft 33 passes through the opposite vertical rods 322 at both axial ends. The two ends of the rotating shaft 33 located axially outside the vertical rod 322 are locked with nuts or pins to prevent the rotating shaft 33 from coming out of the vertical rod 322 .

In order to improve the stability of the bracket 32, a diagonal tie rod 323 is used to reinforce the connection between the vertical rod 322 and the horizontal rod 321.

A supporting plate 41 is fixed to the lower part of the side of the foot plate 4 facing the lower limb pad 1 for supporting the patient's heel. In order to adapt to the shape of the heel, the support plate 41 is set in a downwardly curved arc, and a rubber pad is provided on the top surface to improve the comfort of the foot and avoid affecting the blood circulation of the heel or causing damage to the heel after long-term exercise. pain.

The upper side of the foot plate 4 facing the lower limb pad 1 is fixed with a limit belt 42. The limit belt 42 is mainly used to fix the patient's foot surface, and cooperates with the support plate 41 to limit the foot to prevent the foot from contacting the support plate during exercise. There is a large displacement between 41 or the foot is separated from the foot plate 4. In order to facilitate operation and avoid excessive pressure on the foot surface, the limiting band 42 adopts an elastic band.

The automatic foot function exerciser for bone traction patients also includes a control device for controlling the activation of the air cylinder 21, and the control device can be fixed on the bracket 32.

Further, the control device presets the exercise duration. When the current exercise duration is equal to the preset exercise duration, the control device stops the cylinder 21 and the foot function exercise ends.

The utility model's automatic foot function exerciser for patients with bone traction uses the bracket 32 as the overall support of the movable part. When in use, the patient places the calf on the lower limb pad 1 and extends the foot, and the heel is placed on the arc-shaped support. On the board 41, the sole of the foot is fit with the foot board 4, the front part of the foot passes through the limiting band 42 and the foot surface is fixed with the limiting band 42;

Then the cylinder 21 is started, so that the piston rod 212 drives the drawbar 213 to reciprocate horizontally. The drawbar 213 drives the sliding shaft 22 to slide in the sliding slot hole 233, so that the linkage 23 drives the swing rod 31 to swing back and forth with the rotating shaft 33 as the axis, thereby causing the foot to reciprocate. The board 4 swings synchronously, and the foot placed on the foot board 4 can achieve dorsiflexion and plantar flexion exercises. When the piston rod 212 reaches half of its stroke, the swing rod 31 and the foot board 4 are in a vertical state, so that the swing rod 31 The internal rotation angle and the external rotation angle of the foot plate 4 are equal.

In the utility model, the maximum internal rotation swing angle of the swing rod 31 is 45°, and the maximum external rotation swing angle is 45°, so that the foot can be exercised within a maximum range of 90°. The angle of each swing of the swing rod 31 is uniform. The range of foot activities driven by the foot plate 4 is fixed, and the strength and frequency of foot exercise are stable, thereby enabling the foot to exercise effectively, preventing foot function decline and lower limb thrombosis, and achieving better recovery effects. In other embodiments, the swing angle can be changed, and the specific swing angle can be adjusted by adjusting the stroke of the cylinder 21 so that the internal rotation angle and the external rotation angle of the swing rod 31 are not equal.

When the cylinder 21 is in a non-working state and the piston rod 212 returns to the initial position, the limiting strap 42 can be released from the foot surface, and only the supporting plate 41 is used to support and fix the foot, so that the foot and the leg are in a neutral position to prevent the foot from being free. Suspended state to prevent foot drop.

In other embodiments, the cylinder 21 in the present utility model can be replaced by an electric cylinder, thereby achieving multi-position starting and stopping during the stroke.

The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model in any other form. Any modifications or equivalent changes made based on the technical essence of the present utility model still belong to the scope of the present utility model. Scope of protection claimed.
