Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an active exercise device for stroke patients. Background Art

[0002] "Cerebral stroke" is also known as "stroke" or "cerebrovascular accident (CVA)". It is an acute cerebrovascular disease, a group of diseases caused by sudden rupture of blood vessels in the brain or blockage of blood vessels leading to inability of blood to flow into the brain, resulting in brain tissue damage, including ischemic and hemorrhagic strokes. The incidence of ischemic stroke is higher than that of hemorrhagic stroke, accounting for 60% - 70% of the total number of strokes. After a stroke occurs, due to the different positions of the bleeding or blocked brain areas, the movement of the body parts controlled by the corresponding brain areas will be restricted. The common phenomenon is that the movement of the unilateral face or unilateral limb of the patient is restricted.

[0003] For patients with unilateral limb movement restriction after suffering from stroke, in order to restore the autonomic nerve consciousness and the coordination ability between the nerve and the limb, and effectively restore muscle strength, usually the patient needs to borrow the autonomic consciousness to complete active rehabilitation exercises; the active and conscious exercise of the patient after illness is the key to the degree and speed of the patient's recovery. At present, the autonomous recovery of the unilateral upper limb can be easily assisted by the healthy upper limb to complete the exercise, but for the active exercise of the unilateral lower limb, it is mostly completed by borrowing the healthy upper limb, but the strength of the upper limb is limited and the recovery effect is also poor. The trunk movement of patients with unilateral limb movement restriction is generally not restricted. If the trunk strength can be borrowed to complete the autonomous rehabilitation training of the lower limb, the trunk strength is greater and the autonomous recovery effect will be better, but there is no effective technical solution in the prior art to effectively borrow the trunk strength to complete the autonomous rehabilitation exercise of the lower limb.

[0004] The present invention aims at the above problems and provides an active exercise device for stroke patients. Summary of the Invention

[0005] In order to overcome the problems proposed in the background art, the present invention provides an active exercise device for stroke patients.

[0006] An active exercise device for stroke patients, comprising a trunk portion arranged at the patient's trunk; a foot portion arranged at the patient's foot and / or a leg portion arranged at the knee portion, and a traction rope connecting the trunk portion with the foot portion and / or the leg portion; one or two traction ropes are arranged, the first end of the traction rope is connected to the trunk portion, and the second end is connected to the foot portion and / or the leg portion; a support structure is arranged on a bed body to lift the traction rope, and a through groove for the traction rope to pass through is arranged on the support structure; the support structure also includes a gripping rod for the patient's hand to grasp; a bed fixing structure fixed to the bed body is also arranged at the bottom of the support structure; the trunk portion is divided into a structure worn on or covered on the trunk; the foot portion is a structure that can be worn on the foot; the trunk portion pulls and releases the traction rope along with the movement of the human trunk, and then the traction rope drives the foot portion and / or the leg portion to be lifted and lowered, and finally drives the exercise of the lower limbs. With the above arrangement, the user can grasp the gripping rod with hands while maintaining balance, and the movement of the lower limbs can be driven by the movement of the trunk. The movement of the trunk is an active and conscious activity, which can be a good exercise for consciousness.

[0007] Furthermore, the height of the through slot is higher than the connection between the torso and the traction rope when the patient sits up; but not higher than 20 cm above the shoulders when the patient sits up; this arrangement can ensure that the traction rope is easy to set up so that it does not fall out of the through slot, and can also ensure the comfort of the patient when grasping.

[0018] Further, the threads of the threaded combination of the horizontal sections of the two vertical rods and the two sections of the grasping rod are in opposite rotation directions. This setting can effectively achieve the effect of rotating the grasping rod to simultaneously reduce the distance between the two vertical rods or increase the distance between the vertical rods, and can ensure the effect of clamping the card slot of the base on the bed or withdrawing it from the bed body without being locked.

[0019] Further, 1 - multiple pulleys are provided on the grasping rod, and the pulleys can rotate arbitrarily on the grasping rod.

[0020] Further, one pulley is provided on the same - side limb, and a total of 2 pulleys are provided; rehabilitation exercises can be selected for one - side patients or both affected limbs.

[0029] Further, the foot part is a foot sleeve worn on the foot, and the bottom of the foot sleeve is a hard bottom plate; a fixing member for connecting the first traction rope is provided on the foot sleeve, and the first traction rope gives the foot sleeve a force towards the torso direction. This setting can effectively prevent the foot from turning inwards.

[0030] Further, a second ring is provided on the fixing member, and the traction rope is tied to the fixing member. The fixing member can be sewn on the upper surface of the foot sleeve, or a pasting structure is provided under the fixing member and is adhesively connected to the foot sleeve of the foot.
