Description

multifunctional rehabilitation wheelchair

technical field

The utility model relates to the technical field of medical equipment, in particular to a multifunctional rehabilitation wheelchair.

Background technique

The main purpose of wheelchairs is to replace transportation and assist the elderly and people with disabilities in their daily life and work. However, some patients with lower limb disabilities need to rely on wheelchairs for a long time, and various complications such as muscle atrophy, bedsores, and joint contractures are prone to occur after sitting still for a long time. Therefore, when the patient's condition has recovered to a certain level, appropriate exercise should be carried out as soon as possible to promote recovery. However, the existing wheelchairs either have multiple functions, complex structural designs and high costs, or have relatively single functions, which are difficult to meet the needs of patients in the rehabilitation stage for functional exercise of limbs.

Utility model content

In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

The groove in each side of the handrail is provided with two sliders, and the two ends of the elastic band are respectively fixed to the two sliders.

The general idea of the utility model is: according to the strength requirement of the patient, adjust the position of the first connecting rod in the casing and the position of the slider in the groove, so that the patient can perform strength rehabilitation exercises for the upper and lower limbs simultaneously or separately .

In addition, the utility model also provides the following subsidiary technical solutions:

Further, the front end of the wheelchair frame is provided with a support rod for supporting the sleeve, and when the sleeve is placed on the support rod, the included angle with the vertical direction is 5°-20°. Setting the support bar can prevent the patient from exercising the lower limbs, and the angle between the foot and the thigh after the foot is placed on the pedal is greater than 90°, which conforms to ergonomics and enhances the comfort of the patient.

Further, positioning holes are evenly distributed on the center line of the bottom surface of the groove, a positioning rod is provided at the center of the bottom of the slider, and a protrusion is provided at the center of its upper end surface, and the end of the elastic band is fixed to the protrusion. The length of the slider is smaller than the width of the bottom of the groove and larger than the width of the top of the groove, and the width of the slider is smaller than the width of the top of the groove. When adjusting the position of the slider, put the slider into the groove along the direction of the groove, insert the positioning rod into the corresponding positioning hole, and rotate the slider to ensure that the slider does not shift during the upper limb exercise process.

Further, the distance between the positioning holes is 3cm-5cm.

Further, the foot pedal is rotatably connected to the second connecting rod, and massage wheels are arranged on the back of the foot pedal. In this way, one side of the pedal can put the foot, and the other side can massage the sole of the patient's foot, so as to promote blood circulation and facilitate rehabilitation.

Compared with the prior art, the beneficial effects of the utility model are:

1. The utility model can exercise upper limbs and lower limbs at the same time, and patients can grasp the elastic belt to perform upper limb stretching at any angle. At the same time, the lower limb training device is hingedly connected with the wheelchair frame so that the lower limb training device can be lifted at different angles during lower limb training. Stretching exercise after starting to increase the difficulty of exercise, thereby increasing the variety of options for upper and lower body exercises;

2. The utility model can adjust the position of the first connecting rod in the casing and the position of the slider in the groove according to the strength requirements of the patient, so that the patient can perform stretching exercises of different strength levels;

3. The utility model has a simple structure, is easy to manufacture, and can also be refitted on the basis of existing wheelchairs.

Detailed ways

The utility model is described below in conjunction with the accompanying drawings and embodiments, and the following embodiments are explained with the best effect of the utility model, but these embodiments are not limitations of the utility model.

Example 1:

As shown in Figures 1-3, a multifunctional rehabilitation wheelchair includes a wheelchair frame 1, wheels, a chair back, a seat and armrests 2 on both sides of the seat, and also includes a lower limb training device and an upper limb training device. The lower limb training device comprises a pedal 3, a sleeve 4, a first connecting rod 5 and a second connecting rod 6, the sleeve 4 is hingedly connected to the front end of the wheelchair frame 1, and the pedal 3 and the second connecting rod 6 are rotatable connection, the first connecting rod 5 and the second connecting rod 6 are sleeved in the casing 4, a spring 7 is connected between the first connecting rod 5 and the second connecting rod 6, and the side of the casing 4 is provided with a strip-shaped slot 8, The first connecting rod 5 and the second connecting rod 6 are respectively provided with threaded holes 9, and the outer side of the slot 8 is provided with a handle screw 10 cooperating with the threaded hole 9, and the handle screw 10 connects the first connecting rod 5 and the second connecting rod 6 Fixed on the casing 4, the back of the pedal 3 is also provided with a massage wheel 18.
