Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multi-stage limiting hip exerciser. Background Art

[0002] Before parturition, in order to ensure the physical functions of the parturient, it is necessary to appropriately exercise the hips. Since the parturient is about to give birth, her movement must be restricted to prevent miscarriage. Clinically, a hip exerciser is often used for the parturient to exercise the hips.

[0003] The patent with the publication number of CN221332662U discloses a hip exerciser for parturients before delivery, which includes a main body and two foot pedals. The main body and the foot pedals are both cavity structures with openings at the front side, wherein: two smooth rods are arranged between the left and right inner side surfaces of the main body, and both smooth rods are parallel to the inner bottom surface of the main body. Two springs are sleeved on each smooth rod; both foot pedals are slidably arranged on the two smooth rods, and the two foot pedals are located between the two springs. In this hip exerciser for parturients before delivery, the two foot pedals are slidably arranged in the main body through the smooth rods, and springs are arranged on the smooth rods, so that there is a damping effect when the two foot pedals move away from each other. When the feet of the parturient are respectively placed in the two foot pedals, a gap will be formed between the legs and the hospital bed. When exercising the hips by spreading the feet, the legs of the parturient will not rub against the hospital bed. Therefore, the parturient does not need to lift the legs for a long time, nor will it cause discomfort to the parturient, and the exercise effect is better.

[0004] However, in the above hip exerciser, the damping effect when the two foot pedals move away from each other cannot be adjusted. Therefore, the hip exercise intensity cannot be adjusted according to the target training effect, which has certain limitations. For example, when the parturient only needs to do some mild exercises, the maximum opening distance of the two foot pedals cannot be controlled, which is likely to cause overtraining.
