Description

Rehabilitation pedal

Technical Field

The utility model relates to a rehabilitation pedal belongs to rehabilitation training device technical field.

Background

Clinically, patients are affected by surgical trauma and postoperative bed, and a considerable part of patients are at risk of lower limb Deep Vein Thrombosis (DVT), and severe DVT even affects artery blood supply and causes limb blood supply insufficiency. If the thrombus falls off, pulmonary embolism may occur, and the fatality rate is high. Therefore, it is very important to prevent the occurrence of DVT. Clinically, there are pharmacological and physical means of preventing the onset of DVT. Among them, in terms of physical prevention, some means for passively assisting the movement are used. For example: elastic socks, intermittent inflation and pressurization devices and the like. The device lacks some tools for the patient to actively move when lying in bed according to the actual situation of the patient. Therefore, the rehabilitation pedal appears on the market, is used for patients of various body types, and can actively exercise related muscles and muscle groups when the patients lie in bed under the condition of limited bed-leaving activity so as to strengthen the strength of the muscles, increase the stability of muscle tube joints and effectively prevent deep venous thrombosis and muscular atrophy of lower limbs.

When the existing reciprocating type rehabilitation pedal is used, the existing reciprocating type rehabilitation pedal needs to be placed at the position of the bed tail close to the feet of a patient, the patient lies down, the feet are placed on the pedal respectively, the spring resistance is overcome by the toes, the pedal is pressed, then the pedal is loosened, and the pedal is reset by the restoring force of the spring to complete a training action. The Hall sensor is arranged on the inner side of the pedal, and once the pedal is extruded, the Hall sensor is close to the pedal to trigger counting, so that the purpose of quantitative rehabilitation training is achieved. However, when the patient performs the horizontal type pedaling training, the body of the patient gradually moves away from the pedals under the influence of the reaction force. Finally, the patient who is inconvenient to move needs to be adjusted forward from time to time, and the adjustment can be completed by nursing staff, so that the nursing staff needs to participate in the whole process, and the burden of the nursing staff is increased.

Therefore, in order to solve the problem that the body of a patient is far away from the pedal during the trampling training, the rehabilitation pedal comprises a pedal assembly for the horizontal trampling training of the patient and a shoulder support assembly which is abutted against the shoulder of the patient and prevents the patient from moving.

Each shoulder rest 2 can be independently adjusted in three directions through an adjusting mechanism 3. The three-way adjustment refers to the translational adjustment in the directions of x, y and z axes.

Three-way adjustment herein refers to: the y-axis adjustment of horizontal translation along the direction of the bed head and the bed tail, the x-axis adjustment of horizontal translation vertical to the y-axis, and the z-axis adjustment vertical to the x-axis and the y-axis and up-down adjustment along the vertical direction.

As shown in fig. 2, the existing pedal assembly 1 includes a fixing plate 101, a pedal 102 having a lower end hinged to the fixing plate 101, a return spring 103 disposed between the upper portion of the pedal 102 and the fixing plate 101, and a commercially available proximity counter disposed between the upper end of the pedal 102 and the fixing plate 101 for recording the number of steps, wherein the proximity counter mainly includes a permanent magnet and a hall sensor, the permanent magnet is fixed on the pedal 102, the hall sensor is fixed on the fixing plate 101, and when a patient steps on the pedal, the hall sensor is triggered by the magnetic field of the permanent magnet when the two are close to each other, and a count is performed.

The reset spring 103 adopts a plurality of springs with different elastic coefficients, 3 springs with different elastic coefficients can be arranged from weak to strong, and the reset spring 103 with a proper elastic coefficient is replaced according to different patients or different recovery stages so as to achieve the purpose of gradual rehabilitation training.

As shown in fig. 3 and 4, the adjusting mechanism 3 includes an adjusting plate 301, a sleeve 302, a square inner tube 303, an x-axis adjusting screw 304, a y-axis adjusting screw 305, and a z-axis adjusting screw 306.

The adjusting plate 301 is provided with a horizontal long hole 307, one end of each sleeve 302 is provided with a threaded hole, the other end of each sleeve 302 is provided with a square opening, an x-axis adjusting screw 304 penetrates through the horizontal long hole 307 to fix one end of each sleeve 302 on the adjusting plate 301, the other end of each sleeve 302 is provided with a square opening and is inserted into the corresponding square inner tube 303, and the square inner tube 303 is fixed through a y-axis adjusting screw 305 screwed in from the side face of each sleeve 302.

By loosening the x-axis adjusting screw 304, the sleeve 302 can be translated in the direction of the horizontal long hole 307 (x-axis) of the adjusting plate 301 until the x-axis adjusting screw 304 is locked when the two shoulder rests 2 correspond to the lateral shoulder positions of the patient.

By loosening the y-axis adjusting screw 305, the square inner tube 303 can be stretched in the sleeve 302, two feet of a patient respectively step on the pedal 102, and after the patient lies flat, the y-axis adjusting screw 305 is locked when the two shoulder rests 2 are adjusted to correspond to the shoulder positions of the two sides of the patient.

The square inner tube 303 is fitted with the square open sleeve 302, which can prevent the shoulder rest 2 from rotating, so that the shoulder rest 2 can always keep the direction of gripping the shoulder.

The shoulder rest 2 is provided with a vertical strip-shaped hole 201, and the shoulder rest 2 and the outer end part of the square inner tube 303 are fixed by penetrating the vertical strip-shaped hole 201 through a z-axis adjusting screw 306. According to the body thickness of the patient, the shoulder rest 2 can be adjusted in the z-axis direction, so that the shoulder rest 2 is always as high as the shoulders.

The shoulder rest 2 assembly which is abutted against the shoulder of the patient is arranged at the head of the other end opposite to the pedal assembly 1, so that the problem that the body of the patient moves to the head of the bed when the patient is trampled in training can be prevented. The shoulder rest 2 assembly is provided with an adjusting mechanism 3 for adjusting the shoulder rest 2 in three directions, and can be adapted to the shoulder fixation of patients with different heights and body types.

Example 2
