Description

Lower limb orthosis for rehabilitation therapy

Technical Field

The invention relates to the technical field of multifunctional rehabilitation therapy core components, in particular to a lower limb orthosis for rehabilitation therapy.

Background

Lower extremity orthoses, also known as walkers, are commonly used to help treat patients' lower extremity movement disorders. The lower limb orthotics are used for walking, so that the hip joints and the knee joints of the patient can be bent in an auxiliary mode, and the patient can keep the functional position for a long time. The lower limb orthotics are mainly used for supporting the gravity center of a patient, assisting or replacing the limb function, reducing unnecessary movement of lower limb joints and keeping the lower limbs stable. However, the patient also needs to sit to rest after a certain amount of walking training is completed. For this purpose, patent document CN2261833Y discloses a walking aid, namely a lower limb orthosis, which also functions as a resting chair. However, when it is not used as a resting chair, its folding seat board is folded at the elastic belt, and a partial shelter is formed just on the sight line of the patient in the advancing direction of the front wheel. Moreover, other walking aids available as resting chairs have similar drawbacks.

Detailed Description

The foregoing and additional embodiments and advantages of the present invention are described more fully hereinafter with reference to the accompanying drawings. It is to be understood that the described embodiments are merely some, and not all, embodiments of the invention.

In one embodiment, as shown in fig. 1-2.

The lower limb orthosis for rehabilitation comprises a front supporting leg 1, side beams 2 and a rear supporting leg 3 which are sequentially connected in an n shape, a fixed beam 4 is connected between the two front supporting legs 1, slide rails 5 along the length direction of the two side beams 2 are arranged at the bottom of the two side beams 2, strip-shaped curtain edges 6 which can be pulled open or folded are connected in the slide rails 5 in a sliding mode, and hemp ropes 7 which are uniformly distributed along the length direction of the curtain edges 6 are arranged between the two curtain edges 6. When the curtain edge 6 is pulled open, the hemp ropes 7 are spread along the length direction of the curtain edge 6 to form a chair seat with spaced gaps. When the hemp ropes 7 form the chair surface, the height difference exists between the two adjacent hemp ropes 7, and when the curtain edges 6 are folded, the hemp ropes 7 are gathered to form a rope bundle.

In this embodiment, the arrangement of the front legs 1, the side members 2, the rear legs 3, and the fixing beams 4 is not significantly different from that of the conventional lower limb orthosis. The front support leg 1, the side beam 2 and the rear support leg 3 are connected in sequence to form an n shape, which is not a complete n shape, but the front support leg 1 and the rear support leg 3 are inclined to a certain degree, the front support leg 1 and the rear support leg 3 are splayed, and the side beam 2 is connected between the two, so that the appearance is similar to an n shape. As shown in fig. 2, the bottom of the two side beams 2 is provided with a slide rail 5 along the length direction thereof, and the slide rail 5 is connected with a strip-shaped curtain edge 6 capable of being pulled open or folded in a sliding way. The curtain edges 6 which can be drawn open or drawn in are similar to a track curtain, the curtain edges 6 can be flatly spread out after being drawn open, and the curtain edges 6 can be gathered together after being drawn in. The connection between the curtain edge 6 and the rail 5 is here a sliding connection, also similar to the sliding connection of a track curtain. In this embodiment, if the lower extremity orthotic is to be used as a seat, the elongate curtain edge 6 is simply pulled apart, and the twine 7 is spread along the length of the curtain edge 6 to form a seat surface with spaced gaps. The seat surface resembling a sheaf has spaced gaps. If the chair seat is folded, the hemp ropes 7 are gathered together along with the curtain edges 6 to form a rope bundle. And the adjacent two hemp ropes 7 have height difference, so that the hemp ropes 7 are easier to gather to form a rope bundle. Compared with the chair surface, the shielding surface of the rope bundle is much smaller, so that the sight of the patient in front of the rope bundle is not shielded.

In one embodiment, as shown in FIG. 1.

In the lower limb orthosis for rehabilitation provided by the embodiment, the walking aid handrails 8 are arranged above the front supporting feet 1 and the rear supporting feet 3, and the walking aid handrails 8 are positioned above the side beams 2.

In the present embodiment, the walking aid handrails 8 are provided, so that the patient can carry out walking training by holding the walking aid handrails 8 with his hands. Since the chair surface formed by the twine 7 is already gathered together, in particular on the side close to the fixed beam 4, a space is left between the front leg 1 and the rear leg 3 for the training of the patient. In a preferred embodiment, the rollator handrail 8 is sleeved with a flexible first sleeve 9. The first pipe sleeve 9 is arranged to grab a patient, so that the lower limb orthosis has better use comfort.

In one embodiment, as shown in fig. 1-2.

When the curtain edge 6 is pulled open, the pull rope 12 is supported at the bottom of the hemp rope 7, and the curtain edge 6 can be folded and stored in the storage groove 14 by pulling the limit handle 13.

In the present embodiment, when the pull rope 12 is not pulled, the limit handle 13 abuts against the limit plate 11, and if the curtain edge 6 is pulled to spread the hemp rope 7 to form a seat, the upper side of the curtain edge 6 is fixed in the slide rail 5, and the connection strength can be reinforced by the pull rope 12 below. The bottom of the twine 7 to which the shade edge 6 is attached is supported by a pull cord 12, which is advantageous from the position relationship of the position-limiting plate 11 and the pull piece 10 because the pull piece 10 has a higher position. The patient can sit on the chair surface more securely, and the structure is more stable because the bottom of the chair surface formed by the hemp ropes 7 is supported by the pull ropes 12. As shown in fig. 2, the side member 2 is formed in an "n" shape, and a receiving groove 14 communicating with the slide rail 5 is formed on one side thereof. The receiving groove 14 is formed on one side of the side beam 2 and is substantially perpendicular to the slide rail 5. Then, the limit handle 13 is pulled, and the curtain edge 6 is drawn by the driving of the pull rope 12 and then is pulled continuously along the slide rail 5 until being pulled into the accommodating groove 14. Since the accommodating groove 14 and the sliding rail 5 are not in the same direction, the curtain edge 6 and the hemp rope 7 are not easy to run back along the sliding rail 5 after being pulled into the accommodating groove 14.

In one embodiment, as shown in FIG. 1.

In the lower limb orthosis for rehabilitation provided by the embodiment, the side beam 2 is sleeved with the flexible second pipe sleeve 15. In this embodiment, the second socket 15 is arranged vertically opposite to the first socket 9, so that the lower limb orthosis is also more comfortable to use.
