For the utility model, its seat plate is provided with angle scale 14, can read the opening angle of fork by this scale, and seat plate rear side is provided with handle 12, after the utility model is folded, it is convenient to extract.

The using method of the utility model:

1. Let the child sit on the chair, place the legs in the fixing device of the swing rod, put on the orthopedic shoes, fix the orthopedic shoes on the orthopedic shoe fixing seat, and slide the orthopedic shoe fixing seat back and forth to adjust to the child's In the best position, use the straps on the backrest, seat board and fixing device to fix the child respectively, and then rotate the hand wheel of the orthosis, the two legs of the child can realize the swing between 20°-120° along with the swing bar. Swing and rotate to an angle suitable for children's orthopedics. At this time, a dinner plate can be installed, so that children can eat, play games, read and write, communicate with others and other daily activities on the dinner plate.

2. How to use the orthosis: in the process of rotating the handwheel (as shown in Figures 5 and 6), when the handwheel is rotated forward, the screw rod rotates forward with the The threaded nut block moves forward under the force of the screw thread, and at the same time applies a forward force to the connecting rod, and the connecting rod transmits the force to the left and right swing rods, thereby pushing the two swing rods to open synchronously , rotate the handwheel to open the pendulum to the desired angle (the opening angle can be read through the angle scale on the seat plate), when it is necessary to reduce the opening angle of the pendulum, reverse the handwheel and the nut The block moves backward, thereby driving the pendulum to recover through the connecting rod.

3. The use method and principle of the rotating mechanism: the groove on one side of the rotating shaft is stuck on the crossbeam of the seat plate, and the other side is sleeved on the rotating shaft of the backrest and positioned by the cooperation of the bayonet and the pin hole. The rotating shaft of the front leg and the rear leg The rotating shaft and the backrest rotating shaft are fastened on the seat plate through the rotating shaft card and the central shaft (tighten the central shaft screw rod). During specific production, a U-shaped groove is formed on the side of the rotating shaft of the front leg that is docked with the rotating shaft of the rear leg, and a cylindrical boss matching the U-shaped groove is formed on the side of the rotating shaft of the rear leg that is connected to the rotating shaft of the front leg. The cylindrical boss snaps into the U-shaped groove and limits the opening angle of the front and rear leg shafts. At the same time, the flange boss of the rotating shaft card is provided with a cylindrical boss, and the rear leg shaft is docked with the flange boss. One side of the flange boss is provided with a U-shaped groove matching the cylindrical boss on the flange boss, so as to realize the position limit of the rear leg rotating shaft relative to the rotating shaft card. As shown in accompanying drawing 8, the bayonet pin on the backrest rotating shaft is provided with spring 28, when backrest rotating shaft and rotating shaft card lock, bayonet pin is inserted in the pin hole of rotating shaft card under the active force of spring, when needing to adjust backrest, to Pull the bayonet pin outward, pull the bayonet pin out of the pin hole, and then turn the backrest. After the relative position of the high-speed backrest shaft and the shaft card reaches a suitable angle, insert the bayonet pin into the pin hole.

Folding method: firstly pull out the front section of the two swing rods; then pull out the dinner plate; then fold the pedal back; keep the rear leg still, let the front leg rotate until it coincides with the rear leg; Rotate the front and rear outriggers together to be parallel to the seat board; pull up the left and right latches on the backrest, and rotate the backrest to be parallel to the seat board (the folded shape is shown in Figure 9).

The principle of orthopedics: children with spastic cerebral palsy mainly have excessive muscle tension in the state of activity and nervous tension, manifested as scissors steps, pointed feet, knee flexion, foot valgus, etc. The main purpose of orthopedics is to relax the excessive muscle tension or Decrease the muscle strength of the corresponding antagonistic muscle, and let the two gradually reach or approach the balance.

This multifunctional orthopedic chair is designed according to the clinical orthopedic requirements of children with cerebral palsy. It has many functions, wide application, simple operation, and is easy to carry. It is especially suitable for orthopedic auxiliary treatment or life assistance combined with daily life, study, and entertainment. , Entertainment, convenient, time-saving, labor-saving, money-saving and worry-free.

Indications and orthopedic effects:

1. Adductor muscle tension, pointy feet, knee hyperflexion (used under the guidance of an orthopedist in the early stage): through gradual slow stretching of adductor muscle tension, Achilles tendon tension, knee flexion, etc. in the exercise state, gradually slow down or relax Teach children to do trunk balance exercises in a planned and step-by-step manner while maintaining tension. Through the combination of the two, planned long-term training (3-6 months effective), so that they can gradually achieve the coordination of self-control of limb movements , so as to improve the overall balance or coordination ability of children, and gradually achieve the goal of being able to stand independently and walk independently.

2. Poor balance of sitting, standing, and walking (use it under the guidance of an orthopedist in the early stage): For children with poor balance of sitting, standing, and walking, first train the children's balance by using orthopedic chairs and balance exercises. Sit, when trained to sit smoothly and independently, it will be of great help to the subsequent training of standing or walking.

3. Poor muscle strength of the lower back muscles (used under the guidance of an orthopedist in the early stage): the special posture design of the orthopedic chair can be used to carry out targeted exercises on the lower back muscle strength of children to improve the lower back muscle strength and enhance their Stretch the trunk to achieve the effect of straightening the chest and tightening the abdomen.

4. Weakness of the four muscles and trunk, unable to sit independently: For this situation, the orthopedic chair is mainly fixed or according to the child's sitting posture to prevent spinal deformation, prevent oppression of internal organs, especially the lungs, and reduce manpower.

5. Consolidate the effect of treatment or prevent recurrence: especially for children with hyperflexion of the knee, tense Achilles tendon, and tense adductor muscles, after achieving good results through surgery or various rehabilitation techniques, it is necessary to consolidate the curative effect or prevent it. For recurrence, the orthopedic chair can be used in learning, entertainment or eating, which can consolidate the curative effect and prevent recurrence invisibly.
