Technical Field

[0001] The utility model relates to the technical field of rehabilitation exercises, in particular to the technical field of bed-mounted foot-operated stretching rehabilitation exercise devices.

Background Art

[0002] With the development of aging, the number of elderly people with disabilities, dementia, and cognitive impairments is continuously increasing. Most of this group of people are accompanied by hemiplegia symptoms and lower limb movement disorders, etc. Medical theory and clinical medicine have proven that in addition to early surgical treatment and necessary drug treatment, scientific rehabilitation training can play a very important role in the recovery and improvement of limb motor function. In addition, patients who lie in bed for a long time are prone to form lower limb deep vein thrombosis (after the lower limb deep vein thrombosis breaks off, it may block at the narrow part of the blood vessel with the blood flow and pose a life-threatening risk), which is not conducive to physical health.

[0003] For this part of patients, there is currently a nursing bed dedicated to rehabilitation exercises on the market, such as a rehabilitation nursing bed and its exercise method for facilitating bedridden patients with the publication number of CN114288111A, a multifunctional rehabilitation exercise bed with the publication number of CN117815007A, and a medical nursing rehabilitation exercise bed with the publication number of CN113855480B. However, due to the large floor area of such a dedicated nursing bed, it can only be replaced with an ordinary hospital bed or stored in an extra vacated department, which is actually difficult to implement. That is to say, how to enable patients to perform bed exercises without replacing the hospital bed and vacating extra rooms is an urgent problem to be solved.

[0004] The purpose of the utility model is to solve the problems in the prior art, and propose a bed-mounted foot-operated stretching rehabilitation exercise device, which is convenient to install, has good adaptability, and enables patients to perform lower limb rehabilitation exercises in bed.

[0005] To achieve the above purpose, the utility model proposes a bed-mounted foot-operated stretching rehabilitation exercise device, which includes a foot strap, an elastic pull rope, a pulley, a support frame, a height adjustment mechanism, and a connection mechanism. The height adjustment mechanism is indirectly fixed to the wall surface or the head of the bed through the connection mechanism and can adjust the height of the support frame. The pulley is rotatably connected to the support frame through a wheel frame. One end of the elastic pull rope is fixed to the foot strap, and the other end is fixed to the support frame after passing around the pulley.

[0006] Preferably, it further includes a seat and a lobster buckle. The foot strap is tied to the seat and is in a loop shape. The lobster buckle is hinged to the seat and simultaneously buckles a first positioning ring. A second positioning ring is provided on the support frame. The two ends of the elastic pull rope are respectively tied to the first positioning ring and the second positioning ring.

[0007] Preferably, the height adjusting mechanism includes a base plate, a lead screw, a nut, a slide rail and a driving member. The lead screw is rotatably connected to the base plate through a support rod. The slide rail is parallel to the lead screw and fixed on the base plate. The nut is threadedly connected to the outside of the lead screw and slidably connected to the slide rail through a slider. The lead screw is driven to rotate by the driving member, and the support frame is fixed to the nut.

[0008] Preferably, the driving member is a motor or a hand crank.

[0009] Preferably, the connecting mechanism is an extension bracket. One end of the extension bracket is fixed to the base plate through a fastener, and the other end is driven into the wall through a fastener.

[0010] Preferably, the connecting mechanism is an extension bracket and a clamp. Both ends of the extension bracket are respectively fixed to the base plate and the clamp through fasteners, and the clamp can be clamped on the head of the bed.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1) By fixing one end of the elastic drawstring to the footrest strap and the other end to the support frame after passing around the pulley, a patient lying flat can perform rehabilitation exercises on the lower limbs during the process of moving the lower limbs and stretching the elastic drawstring. Moreover, the support frame can also adjust the installation height through the height adjusting mechanism, thereby improving the adaptability of the device to patients with different body types and lower limb flexibility;

[0013] 2) By adding a belt seat, a lobster buckle and a first positioning ring between the footrest strap and the elastic drawstring, and indirectly connecting the elastic drawstring to the support frame through a second positioning ring, it is convenient for the user to freely disassemble and replace the footrest strap and the elastic drawstring as needed;

[0014] 3) By jointly using the base plate, the lead screw, the nut, the slide rail and the driving member to form a height adjusting mechanism, a motor or a hand crank can be used as the driving member to drive the lead screw to rotate, so that the support frame and the components connected thereto move up and down along the lead screw and the slide rail together with the nut. Moreover, the base plate can be directly installed on the wall near the hospital bed by using the extension bracket and the fastener, or can be clamped to the head of the bed by using the extension bracket, the fastener and the clamp, and the installation and use are very convenient.

[0015] The features and advantages of the present utility model will be described in detail through embodiments in conjunction with the accompanying drawings.
