Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an adjustable critical care rehabilitation training walking aid mechanism. Background Art

[0002] Walking training is the most critical and important training for patients with limb disabilities after stroke to return to their families and society. It is a periodic, mobile exercise involving multiple joints and muscle groups throughout the body. Normal walking is a highly automated, coordinated, uniform, and stable exercise, and it is also a highly energy-efficient exercise. When conducting walking training, a walking aid mechanism is required, and most of the existing walking aid mechanisms are four-legged frame walkers. The existing four-legged frame walker is composed of four vertical support rods and multiple horizontally arranged connecting rods. When using it, the patient holds the connecting rods on both sides with both hands to support the body for walking training. The existing walkers have the following shortcomings: When using a walker, the patient needs to switch from a sitting position to a standing position. However, the patient's lower limb strength is insufficient, so they need to hold the connecting rod of the walker with both hands and use the strength of their upper limbs to stand. However, in order to facilitate patients to train in a standing position, the connecting rods of the walker are set at a higher position. When holding the connecting rod in a sitting position, the arms are tilted upward. In this position, it is difficult for patients to complete standing with their own upper limb strength. Therefore, a walker is needed that can facilitate patients to stand on their own.

[0003] The parts of existing walkers that contact the ground are usually divided into two types: a flat surface and universal wheels. When using a walker with a flat surface, the patient needs to often lift the walker and then move it forward a short distance. However, the patient's lower limbs are weak, and the body has no support when moving the walker, which makes it easy for the patient to fall. When using a walker with universal wheels, it is difficult for the patient to control the direction of the walker because the universal wheels are flexible and easy to roll. If the patient has an unstable center of gravity, the universal wheel walker cannot provide support for the patient, and the patient is prone to fall. Therefore, a walker is needed that can switch between support and movement, which is convenient for the patient to push and can provide sufficient support to the patient. Summary of the invention

[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0007] Specifically, the limiting device includes a plurality of first limiting grooves fixed on the first connecting rod, a plurality of first mounting grooves fixed on the first connecting rod, a first limiting head slidably arranged on the first mounting groove, and a second spring having one end fixed on the first limiting head and the other end fixed on the first mounting groove.

[0008] Specifically, the first locking device includes a first rack symmetrically slidably arranged on the third sliding groove, a plurality of third springs with one end fixed on the first rack and the other end fixed on the third sliding groove, a second inclined groove fixed on the first rack, and a second slider slidably arranged on the first frame and in contact with the second inclined groove.

[0009] Specifically, the second adjustment component includes a sixth slide groove fixed on the second connecting rod, a second pressing block slidably arranged on the sixth slide groove, a fourth spring fixed at one end on the second pressing block and fixed at the other end on the second connecting rod, a second adjustment rod fixed on the second pressing block and passing through the second connecting rod, a third adjustment rod rotatably arranged on the second adjustment rod, a second locking device fixed on the first frame, and a third inclined groove fixed on the linkage rod.

[0010] Specifically, the second locking device includes a second rack symmetrically slidably arranged on the third slide groove, a plurality of fifth springs with one end fixed on the second rack and the other end fixed on the third slide groove, a fourth inclined groove fixed on the second rack, and a third slider slidably arranged on the first frame and in contact with the third inclined groove; the third slider and the linkage rod are connected by a second traction rope.

[0011] Specifically, the second locking device includes a second rack symmetrically slidably arranged on the third slide groove, a plurality of fifth springs with one end fixed on the second rack and the other end fixed on the third slide groove, a fourth inclined groove fixed on the second rack, and a third slider slidably arranged on the first frame and in contact with the third inclined groove; the third slider and the linkage rod are connected by a second traction rope.

[0012] Specifically, the release assembly includes a seventh slide groove fixed on the third connecting rod, a third pressing block slidably arranged on the seventh slide groove, a fourth adjusting rod fixed on the third pressing block and passing through the third connecting rod, a fifth inclined groove fixed on the linkage rod, and a lifting device fixed on the third pressing block and the first frame.

[0013] Specifically, the lifting device includes a third rack fixed on the third pressing block and passing through the third connecting rod and the first frame, a first gear rotatably provided on the first frame and meshing with the third rack, a second gear rotatably provided on the first frame and meshing with the first gear, a fourth rack fixed on the movable bracket and meshing with the second gear, a guide rod with one end fixed on the movable bracket and the other end fixed on the first frame, and a sixth spring with one end fixed on the movable bracket and the other end fixed on the first frame; the movable bracket and the round rod are connected by a third traction rope.

[0014] The beneficial effects of the present invention are: (1) The first connecting rod is tilted and one end is lower. When in use, the lower end is placed close to the edge of the bed. When the patient uses it, since the starting height of the first connecting rod is relatively low, the patient can easily support the body and gradually move the arms alternately along the tilt angle of the first connecting rod to support the body to stand. Compared with the existing walking frame, the patient can perform standing training by himself without the need for medical staff to assist in standing.

[0015] (2) Compared with the existing walker, the patient can perform standing training by himself without the assistance of medical staff; the second connecting rod is the part that the patient holds when performing walking training. The connecting rod of the existing walker is set horizontally, which causes the patient's wrist to be greatly bent when using it, and the patient needs to continuously grasp the connecting rod to support the body, so the wrist is easily painful. The inclined setting of the second connecting rod can make the patient's wrist part not need to be bent, and only need to bend the elbow to hold the second connecting rod. Long-term walking training will not cause wrist pain. In addition, the height of the second connecting rod is relatively high, and the patient does not need to bend over to grasp it, which avoids the patient's back pain caused by long-term training.

[0016] (3) The existing walking frame lacks anti-tilt support for the frame. If a patient falls while using it, the walking frame cannot support the patient and will be pushed down by the patient. The present invention increases the support for the first frame in the tilting direction by providing a first support rod and a support plate to prevent the first frame from tipping over. At the same time, the first support rod increases the support area after rotation, making the first frame more stable. When the patient is about to fall, he can support his body by grasping the first frame. Compared with the existing walking frame, the present invention improves the safety of patients during training.

[0017] (4) The device can switch between support and movement, making it easier for patients to push and providing sufficient support for patients. It provides support when taking steps, making it easier for patients to exert force and prevent them from falling. When the walker needs to be moved, the rollers are in contact with the ground, making it easier for patients to push, and patients do not need to move the walker. BRIEF DESCRIPTION OF THE DRAWINGS
