Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training devices, and in particular to an ankle pump exercise training device for preventing deep vein thrombosis of lower limbs. Background Art

[0002] Deep vein thrombosis (DVT) in the lower extremities is a common vascular disease in clinical practice, with a higher incidence rate in patients undergoing surgery, being bedridden for a long time, or having limited mobility. Ankle pump exercises, as an effective means of promoting lower extremity venous blood return and preventing DVT through ankle flexion and extension, have been widely used in rehabilitation training. However, existing ankle pump exercise training devices still have the following shortcomings in practical applications: Existing training devices lack an accurate motion monitoring mechanism, making it difficult to quantitatively assess whether the patient's ankle dorsiflexion range of motion meets the standard. When patients train on their own, there is a lack of real-time feedback and reminder functions, making it difficult for patients to grasp the duration of the movement to meet the standard. Insufficient training time or irregular movement maintenance may reduce the prevention effect, while also increasing the supervision burden on medical staff and making it impossible to achieve efficient autonomous rehabilitation training. Existing devices mostly focus on basic stepping and pressing functions, and have not formed a complete closed loop of "posture calibration-motion monitoring-automatic reminder". In long-term rehabilitation training, patients may gradually ignore the standardization of movements due to the lack of scientific guidance and feedback mechanisms, resulting in a significant reduction in the prevention effect of deep vein thrombosis in the lower limbs.

First, the patient places the soles of both feet against the rubber pressure pad 101. The doctor then guides the patient to perform ankle pump exercises. When the patient's feet press against the rubber pressure pad 101 and stretch forward, the pressure block 1 rotates backward along the two side support blocks 201 through the rotational installation cooperation of the rotating shaft 102 and the bearing.

The end faces are in a parallel state, and the button end of the in-place monitoring switch 301 is pressed and contacted with the rear end face of the stepping block 1. Then, the doctor can rotate the locking nut 309 along the stud 308 to make the locking nut 309 tightly fit with the matching plate 3010, thereby limiting and fixing the angle of the current pressing contact plate 3. This design is beneficial for subsequent patients to perform ankle pump operation training on their own.

The in-place monitoring switch 301 is in a pressed and started state, and it gives a feedback signal to the microcontroller 207. The microcontroller 207 controls the timing module 206 to start. When the five-second timing value of the timing module 206 is reached, the timing module 206 feeds back a signal to the microcontroller 207.
