In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides an arm resumes uses medical device, includes the box, is provided with a pair of support in the box, rotationally is provided with the pivot between should to the support, is provided with worm wheel and at least one rim plate in the pivot, and the below of worm wheel is provided with rather than complex worm, and the lateral part of rim plate is connected with link mechanism, and the upper end of link mechanism is connected with the hand portion of gripping after stretching out the box.

The invention is also characterized in that:

the connecting rod mechanism comprises an L-shaped connecting rod and a straight connecting rod, the L-shaped connecting rod is hinged to the side portion of the wheel disc through a pin shaft, and two ends of the straight connecting rod are hinged to the L-shaped connecting rod and the support through pin shafts respectively.

The number of discs is two.

The top of the box body is provided with a pair of sliding grooves, and the upper end of an L-shaped connecting rod in each connecting rod mechanism extends out of the corresponding sliding groove respectively.

The worm is connected with a motor.

The motor is a stepping motor.

The upper surface of the hand holding part is provided with an inwards concave arc surface.

The two ends of the rotating shaft are respectively and rotatably arranged in the corresponding brackets through bearings.

The invention has the beneficial effects that: on one hand, compared with the traditional apparatus, the arm rehabilitation training apparatus is smaller in size and convenient to carry for training at any time; on the other hand, the rehabilitation training of the arms is more targeted, the activation training of arm muscles is achieved by driving the reciprocating rotation motion of the arms through a machine, the speed is adjusted to better adapt to the situation of each person, and the requirement hope of a user for a product is achieved; the convenient design and the targeted training content enable the user to obtain better use feeling and training effect.

Drawings

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic view of a medical device for arm recovery according to the present invention;

FIG. 2 is a front view of FIG. 1;

fig. 3 is a side view of fig. 2.

In the figure, 1, a box body, 2, a rotating shaft, 3, a wheel disc, 4, a worm, 5, a motor, 6, a bracket, 7, a worm wheel, 8, a hand holding part, 9, an L-shaped connecting rod and 10, a straight connecting rod.

Detailed Description

The following embodiments are described in detail with reference to the accompanying drawings, so that the implementation process of the present invention for solving the technical problems and achieving the technical effects by applying technical means can be fully understood and implemented.

As shown in figure 1, the medical device for arm recovery comprises a box body 1, a pair of brackets 6 are arranged in the box body 1, a rotating shaft 2 is rotatably arranged between the brackets 6, a worm wheel 7 and at least one wheel disc 3 are arranged on the rotating shaft 2, a worm 4 matched with the worm wheel 7 is arranged below the worm wheel 7, a connecting rod mechanism is connected to the side part of the wheel disc 3, and a hand holding part 8 is connected to the upper end of the connecting rod mechanism after extending out of the box body 1.

When patient carries out the rehabilitation training, patient's hand is put on hand portion 8 of gripping, later starts worm 4, and worm 4 drive worm wheel 7 rotates, drives pivot 2 when worm wheel 7 rotates and also slowly rotates together. Meanwhile, the connecting rod mechanism drives the hand holding part 8 to do slow curvilinear motion, so that the arms of the patient can be exercised. The medical device for arm recovery has a simple overall structure, is convenient to carry, and can complete arm recovery training of a patient at any time and any place.

Referring to fig. 2 and 3, in the arm recovery medical device according to the present invention, the link mechanism preferably has a structure in which: mainly comprises an L-shaped connecting rod 9 and a straight connecting rod 10, wherein the L-shaped connecting rod 9 is hinged on the side part of the wheel disc 3 through a pin shaft, and two ends of the straight connecting rod 10 are respectively hinged on the L-shaped connecting rod 9 and the bracket 6 through pin shafts.

Referring to fig. 2 and 3, in the arm recovery medical device of the present invention, the number of the roulette plates 3 is two.

Each wheel disc 3 is connected with a connecting rod mechanism and a hand holding part 8 respectively, and a patient can put two hands at the hand holding part 8 at the same time, so that the two hands can carry out rehabilitation training at the same time, and the rehabilitation training time is greatly shortened.

Referring to fig. 2 and 3, in the arm recovery medical device of the present invention, a pair of sliding grooves are formed in the top of the housing 3, and the upper end of the L-shaped link 9 in each link mechanism extends out of the corresponding sliding groove.

The upper ends of the L-shaped links 9 respectively extend out of the corresponding sliding slots and then slide along the sliding slots, thereby ensuring that the hand grip 8 can move in a predetermined curved track.

Referring to fig. 2 and 3, in the arm recovery medical device of the present invention, a motor 5 is connected to a worm 4.

The worm 4 is connected with a rotating shaft of the motor 5, and the rotating speed of the motor 5 can be controlled to realize the transmission speed of the worm wheel 4.

Referring to fig. 2 and 3, in the arm recovery medical device of the present invention, the motor 5 is a stepping motor, which facilitates precise control.

Referring to fig. 2 and 3, in the medical device for arm recovery of the present invention, the upper surface of the hand-holding portion 8 is provided with an inwardly concave arc surface, so that the patient can place his hand in the inwardly concave arc surface, which is convenient for rehabilitation training.

Referring to fig. 2 and 3, in the medical device for arm recovery of the present invention, both ends of the rotation shaft 2 are rotatably provided in the corresponding brackets 6 through bearings, respectively.

Therefore, compared with the traditional apparatus, the arm rehabilitation training apparatus has smaller volume and is convenient to carry for training at any time; secondly, the rehabilitation training of the arm is more targeted, the reciprocating rotation motion of the arm is driven by the machine to achieve the activation training of arm muscles, the speed is adjusted to better adapt to the condition of each person, and the requirement hope of a user on a product is achieved. The convenient design and the targeted training content of the invention enable the user to obtain better use feeling and training effect.
