Description

Technical Field

[0001] The utility model belongs to the technical field of lower limb rehabilitation equipment, and in particular relates to a counting-type bed foot pedal device. Background Art

[0002] Patients with single lower limb fractures or long-term bedridden patients often lack exercise because they cannot get out of bed and move around. They are at risk of lower limb venous thrombosis and lower limb swelling, and need to be guided to perform ankle pump exercises in bed. Ankle pump exercises refer to the movement of the ankle joint through the contraction of the lower limb muscles, so that the lower limb muscles act like a pump, promote blood and lymph circulation in the lower limbs, and then promote the reduction of lower limb swelling, prevent lower limb thrombosis, and help prevent muscle atrophy and ankle stiffness. Therefore, helping patients to perform appropriate lower limb exercises is an important part of comprehensive treatment. The current exercise methods are: a. Let the patient kick the bed end baffle with his feet; b. Let the patient kick the hand of the staff or companion; c. Let the caregiver or medical staff help the patient to exercise his limbs. The above method has the following problems: a. When patients are asked to kick the hands of staff or their companions, the exercise time cannot be arbitrary and they need staff or companions by their side; b. The strength cannot be accurately controlled; if it is too small, the exercise effect cannot be achieved, and if it is too large, the patient will feel uncomfortable; c. There are inevitably problems such as irregular movements. The process is very cumbersome and greatly increases the workload of medical staff. Utility Model Content

[0008] As described in the counting type bed foot pedal device, the left and right pedal assemblies further include a rotating crankshaft rod, a left pedal and a right pedal. The rotating crankshaft rod is laterally and rotatably arranged through the upper end of the rear bracket. The left pedal and the right pedal are respectively and symmetrically arranged at the left and right ends of the rotating crankshaft rod. The counter is arranged between the left pedal and the right pedal.

[0009] As in the counting-type footrest device on the bed, the thigh top plate is a rectangular plate, and the extended surface of the thigh top plate is perpendicular to the rotating surface of the rotating bar relative to the front bracket.

[0010] As in the counting-type bed footrest device, the thigh support assembly also includes a support rod, one end of which is rotatably connected to the head end of the base, and the other end is connected to the side of the rotating bar facing away from the head of the bed.

[0014] The beneficial effects of the technical solution of the utility model are:

[0015] The patient flexes and extends the ankle, pushes the pedal with the forefoot, and performs ankle pump exercises independently, thereby exercising the lower limb function. This can effectively prevent deep vein thrombosis of the lower limbs, practical muscle atrophy, and lower limb swelling, and the exercise time is controllable. The doctor or rehabilitation therapist can record the patient's exercise volume in a timely and accurate manner through the number of circles on the counter, arrange the patient's exercise volume reasonably, and clarify the rehabilitation training goals.

[0022] See also Figure 1 As shown, the counting foot pedal device of the utility model is detachably arranged on the bed body, and specifically includes a base 1 whose head and tail ends correspond to the head and tail ends of the bed body, the head end of the base 1 is rotatably connected to the front bracket 2, and the tail end of the base 1 is rotatably connected to the rear bracket 3, the rotation planes of the front bracket 2 and the rear bracket 3 relative to the base 1 are perpendicular to the horizontal plane, the upper end of the front bracket 2 is rotatably connected to the thigh support assembly, and the upper end of the rear bracket 3 is provided with left and right pedal assemblies with a counter 4.

[0023] In a preferred embodiment, the front bracket 2 and the rear bracket 3 are both double parallel straight rods.

[0024] The thigh support assembly includes a thigh top plate 5, a rotating bar 6 and a sleeve 7. The upper end of the rotating bar 6 is rotatably connected to the upper end of the front bracket 2. The sleeve 7 is sleeved on the rotating bar 6 and can slide back and forth along the rotating bar 6 and then stop. The thigh top plate 5 is fixed to the side of the sleeve 7 facing the head of the bed.

[0025] The thigh top plate 5 is a quasi-rectangular plate, and the extension surface of the thigh top plate 5 is perpendicular to the rotation surface of the rotating bar 6 relative to the front bracket 2.

[0026] A plurality of tooth grids 8 distributed along the length direction of the rotating bar 6 are provided on the side of the rotating bar 6 facing away from the bed head.

[0027] Furthermore, the thigh support assembly further includes a support rod 9, one end of which is rotatably connected to the head end of the base 1, and the other end of which is connected to the side of the rotating bar 6 facing away from the head of the bed. In conjunction with the rotation angle adjustment of the rotating bar 6 and the front bracket 2, the other end of the support rod 9 is connected to the tooth grid 8 at different positions, so that the rotating bar 6 can be further fixed at different angles.

[0028] It is understandable that the rotational connection between the front bracket 2, the rear bracket 3, the support rod 9 and the base 1, the rotational connection between the rotating bar 6 and the front bracket 2, and the connection between the sleeve 7 and the rotating bar 6 can all be achieved by bolts 0. The relative angles between the front bracket 2, the rear bracket 3 and the base 1 are adjusted by bolts 0 to suit patients of different body shapes to perform comfortable pedaling activities. After adjusting to a suitable angle, tighten the bolts 0 to fix the brackets on both sides of the base 1.

[0029] Continuing to refer to the figure, the left and right pedal assemblies also include a rotating crankshaft rod, a left pedal 10 and a right pedal 11. The rotating crankshaft rod is laterally rotatably arranged on the upper end of the rear bracket 3. The left pedal 10 and the right pedal 11 are respectively rotationally symmetrically arranged on the left and right ends of the rotating crankshaft rod. The counter 4 is arranged between the left pedal 10 and the right pedal 11 to record the number of pedaling circles of the patient.

[0030] The counter 4 is an infrared counter. The infrared probe can be arranged on the side of the counter 4 facing the pedal. When the pedal is detected to pass, the infrared ray is blocked and the count is +1, and so on. The infrared counting method belongs to the prior art.

[0031] In a preferred embodiment, the bottom of the base 1 is detachably connected to a supporting telescopic rod 12, which is flush with the unit width of the bed when fully extended. The two ends of the supporting telescopic rod 12 are bent downward to form hooks 13, which can hook the bed frame to fix it.

[0032] When in use, the patient lies on the left side of the pedal device shown in the figure, and leans the two thighs against the position of the thigh top plate 5. The thigh top plate 5 can provide support for the thighs, increasing the patient's own comfort during pedaling activities. The patient places both feet on the left and right pedals to perform pedaling exercises, and the counter 4 records the number of turns of the pedals during the patient's exercise, timely and accurately recording the patient's exercise amount, and the patient can be given a reasonable amount of exercise according to the number of turns of the counter 4.

[0033] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
