Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary equipment, and in particular to a multifunctional lower limb deep vein thrombosis prevention device. Background Art

[0002] In clinical work, many patients suffer from insufficient blood perfusion due to long-term bed rest, which in turn leads to neuromuscular atrophy, slow blood flow, and is prone to deep vein thrombosis (DVT) in the lower limbs. At present, the safer treatment for lower limb DVT is physical therapy, among which ankle pump exercise and pneumatic therapy are the more common physical preventive measures in clinical practice. Ankle pump exercise can promote blood circulation, help prevent muscle atrophy and ankle stiffness, and is the most convenient, economical and effective way to prevent lower limb DVT. Pneumatic therapy promotes local blood circulation and reduces the risk of lower limb DVT by repeatedly applying pressure and decompressing the affected limb and performing rhythmic and regular muscle massage. Compared with a single preventive measure, many clinical studies have shown that ankle pump exercise combined with pneumatic therapy can give full play to the synergistic effect and has a good effect on the prevention of lower limb DVT.

[0003] Traditional ankle pump exercise relies on medical staff to manually flex and extend the patient's feet continuously to drive the ankle joint movement and promote blood circulation. However, since each treatment needs to last for a long time, it will bring a heavy burden to medical staff. At present, there are also special ankle pump training devices in the prior art, but the structure and function of the ankle pump training device in the prior art are too simple. It is mainly composed of a pedal, a leg fixing device and a motor used to drive the pedal to rotate back and forth. Its structure is simple. Although it can complete the flexion and extension of the foot, it cannot press the user's calf while flexing and extending the foot. Therefore, it cannot cooperate with the operation of the ankle pump to perform air pressure treatment on the calf in a timely and effective manner; in addition, since the sole of the foot is in contact with the pedal for a long time and there are many bacteria on the sole of the foot, the pedal is easily eroded by bacteria. The existing ankle pump training device cannot automatically complete the disinfection operation after use, thereby bringing additional work burden to medical staff or managers. To this end, this scheme proposes a multifunctional lower extremity deep vein thrombosis prevention device. Summary of the invention

[0004] The multifunctional lower limb deep vein thrombosis prevention device proposed by the present invention solves the problem that the ankle pump training device in the prior art cannot perform air pressure treatment on the calf in time when in use and cannot be disinfected in time after use.

A counter 46 for recording the number of rotations of the connecting shaft 45 is installed on one of the side panels 5. The counter 46 includes a display and a touch sensor. The output end of the touch sensor is connected to the display. A touch block is fixed on the connecting shaft 45. When the connecting shaft 45 rotates a certain angle, the touch block abuts against the touch sensor. At this time, the touch sensor will transmit the number of times sensed to the display, thereby achieving an automatic counting effect.

[0050] Combination Figure 5 As shown, a baffle 51 is fixed to the top surface of the pedal 6 on one side close to the connecting shaft 45, and two fixing straps 52 are installed on the top surface of the pedal 6 away from the connecting shaft 45, and the other ends of the two fixing straps 52 are fixed by Velcro. When in use, the user places the sole of the foot on the top surface of the pedal 6, supports the heel part with the baffle 51, and then ties the fixing strap 52 to the instep, so as to fix the sole of the foot on the pedal 6. Afterwards, as the pedal 6 reciprocates, it can drive the user to perform rehabilitation training for the ankle joint.

When in use, the mounting plate 2 is first tilted to the side away from the pedal 6, and then the insertion rod 8 is inserted into the insertion hole 9, and the positioning column 10 is pulled outward at the same time. The spring one is compressed, and after the bottom of the insertion rod 8 contacts the bottom of the insertion hole 9, the positioning column 10 is released. Under the action of the spring, the positioning column 10 is clamped into the clamping hole, thereby locking the insertion rod 8 to prevent the mounting plate 2 from rotating during use. Then the user steps on the pedal 6 and fixes it, and then leans the calf against the guard plate 3, and then ties multiple inflatable straps 4 to the user's calves respectively, and the Velcro adhesive point of the inflatable strap 4 is located on the front of the calf, thereby completing the fixation of the user's leg.
