Description

Rehabilitation training device for upper limb fracture

Technical Field

The invention particularly relates to a rehabilitation training device for upper limb fracture.

Background

Fracture refers to the complete destruction or continuous interruption of bones, and when the strength borne by the bones exceeds the maximum strength which can be borne by the bones, the fractures occur, and most patients can recover the original functions after timely and proper treatment. The treatment of fracture includes three stages of reduction, fixation and rehabilitation.

Rehabilitation therapy is an important part in fracture treatment, and reasonable functional exercise is actively and actively carried out, so that not only can complications be prevented, but also the functions of affected limbs can be recovered as early as possible. The rehabilitation form of the upper limb in the middle and later stages of fracture should gradually move the upper and lower joints of the fracture with the help of medical care personnel, and gradually increase the number, amplitude and strength of the movement. In the prior art, the patient can hardly move the affected limb with the other hand, so that the joint movement can be only assisted by medical staff.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the rehabilitation training device for the fracture of the upper limb, which can help the patient to move the joint of the affected limb and improve the convenience.

In order to achieve the purpose, the invention is realized by the following technical scheme: a rehabilitation training device for upper limb fracture comprises a fixed frame;

the two driving parts are symmetrically arranged on the fixed frame and comprise screw rods and sliding seats, one ends of the screw rods are rotatably connected with the fixed frame, the two screw rods are parallel and arranged towards the same direction, and the sliding seats are in threaded connection with the screw rods;

the clamping part is arranged between the two driving parts and comprises a clamping sleeve, a universal ball and a telescopic rod, the telescopic rods are arranged at two ends of the clamping sleeve, and one end of each telescopic rod, which is far away from the clamping sleeve, is connected with the sliding seat through the universal ball; and

and the rotating shaft can be detachably connected with the other end of the screw rod.

Move the mount to patient's body, put into the cover that presss from both sides with the upper limbs that need rehabilitation training to be connected the rotation axis with one of them lead screw, the patient rotates the rotation axis through another hand, drives the lead screw and rotates, thereby makes the sliding seat remove, and the sliding seat passes through the telescopic link and drives the cover that presss from both sides and remove and rotate, thereby lets the upper limbs accomplish the joint activity of bent elbow.

The rehabilitation training device for the fracture of the upper limb has the beneficial effects that: under the condition that does not have medical personnel, can let the patient move about by oneself and suffer from the joint of limb, promoted the convenience to can guarantee security and travelling comfort better through oneself control.

The device further comprises two accommodating blocks which are respectively arranged at the two driving parts, wherein the accommodating blocks are provided with through holes, and one end of each accommodating block is hinged with the fixed frame;

the rotating shaft is inserted in the through hole and is connected with the through hole in a sliding mode.

When the rotating shaft is not used, the rotating shaft is detached from the screw rod, and the accommodating block is rotated, so that the occupied space is avoided.

Furthermore, one end, far away from the hinge joint, of the accommodating block is magnetically connected with the fixing frame.

The magnetic connection enables the receiving block to be fixed on the fixing frame when not in use.

Furthermore, a limiting block is arranged on the fixing frame and can block the rotation of the accommodating block.

Furthermore, a slot is formed in one end, far away from the fixing frame, of the screw rod, and a key slot is formed in the inner wall of the slot;

one end of the rotating shaft, which is close to the screw rod, can be inserted into the slot, and is provided with a guide key which can be inserted into the key slot.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 4, the present invention provides a rehabilitation training device for fracture of upper limb, comprising a fixing frame 10, a driving part 20, a clamping part 30 and a rotating shaft 40, wherein the fixing frame 10 is moved to the side of a patient, an affected limb is placed in the clamping part 30, and the rotating shaft 40 is connected with the driving part 20, so as to drive the affected limb to perform elbow joint movement.

Specifically, the driving parts 20 are provided in two, symmetrically disposed on the fixing frame 10, so that they can be conveniently operated while being placed on both sides of the patient's body. The driving part 20 comprises a screw rod 21 and a sliding seat 22, one end of the screw rod 21 is rotatably connected with the fixed frame 10, the screw rods 21 of the two driving parts 20 are arranged along the horizontal direction and in the same direction, the sliding seat 22 is in threaded connection with the screw rod 21, and the screw rod 21 can drive the sliding seat 22 to move along the horizontal direction.

The clamping portion 30 is disposed between the two driving portions 20, and includes a clamping sleeve 31 and an expansion link 32, the clamping sleeve 31 is used for placing an upper limb of a patient to be moved, two sides of the clamping sleeve 31 are connected to the sliding seats 22 on two sides through the expansion link 32, two ends of the expansion link 32 are respectively hinged to the clamping sleeve 31 and the sliding seats 22, so that the clamping sleeve 31 can rotate in a vertical plane relative to the sliding seats 22. In this embodiment, the jacket 31 includes an outer frame 310 and an inner sleeve 311, and the telescopic rod 32 is hinged to the outer frame 310.
