Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical care instruments, in particular to an automatic ankle pump exercise device with foot massage function. BACKGROUND

[0002] With the change of modern lifestyle, lower limb health problems are increasingly prominent, providing a realistic background for the emergence of automatic ankle pump exercise devices with foot massage function. At present, groups such as office workers and long-distance drivers are prone to lower limb acidosis, edema, and a greatly increased risk of deep vein thrombosis due to long-term maintenance of the same posture, resulting in a significant lack of lower limb activity, which slows blood circulation and blocks venous return. Postoperative patients and long-term bedridden people often suffer from muscle atrophy and ankle stiffness due to immobilization of the lower limbs, which seriously affects the rehabilitation process and quality of life. As people age, joint degeneration and muscle strength decline, and lower limb circulation function decreases, often leading to cold feet, numbness, and other discomforts, and active exercise capacity gradually declines.

[0003] Before the emergence of this device, there have been some solutions to these problems, but there are obvious limitations. For lower limb circulation and muscle joint problems, traditional ankle pump exercises require patients to actively exert force to complete them, but many groups such as postoperative weak individuals and the elderly either cannot complete them or do not perform them correctly, making it difficult to achieve the desired results, and long-term adherence is low. Simple foot massage devices can relieve some fatigue, but they cannot exercise the ankle joint and cannot fundamentally improve lower limb blood circulation and muscle joint function. Some rehabilitation devices have single functions, are complex to operate, and are not comfortable to use, making it difficult to meet the diverse needs of different groups.

[0004] Chinese Patent No. CN222304291U discloses an intelligent ankle pump exercise massage instrument. The device includes a control instrument and two air pressure leg sleeves, a connection part for connecting the control instrument and the air pressure leg sleeves, a rotary motor provided on the air pressure leg sleeve, a rotary frame connected to the output end of the rotary motor, a mounting frame provided on the rotary frame, a driving part located on the mounting frame, a foot boot connected to the driving part, and a massager and a heater provided on the foot boot. The device can massage the soles of patients and heat their feet through the massager. When operating, the combination of foot massage can achieve meridian conditioning, and constant temperature heating makes patients feel comfortable while further promoting blood circulation. At the same time, the air bag provided in the air pressure leg sleeve can prevent patients from causing limb damage due to restlessness, and the lower limb muscle pump combined with the negative pressure effect of the chest cavity can improve the peak velocity of femoral vein blood flow, increase the amount of lower limb venous blood return, and effectively prevent deep vein thrombosis of the lower limbs.

[0005] However, such ankle pump exercise massage devices as described above are currently used in clinical practice to prevent thrombosis, foot drop and pressure sores, and are mostly designed with "single function", lack of coordinated linkage, and patients need to use thrombosis prevention devices (such as air pressure pumps), foot drop correctors (such as foot supports) and heel protection pads at the same time, which not only is complicated to operate, but also may reduce the use experience due to physical interference (such as compression and displacement) between devices, resulting in poor patient compliance; the movement mode of each device (such as the squeezing of the air pressure pump and the fixation of the foot support) lacks adaptability to human physiological activities, for example, the movement trajectory of the existing rotating or flexion and extension devices often does not conform to the natural activity angle of the ankle joint (such as uneven stress on the medial and lateral sides), which is easy to cause joint discomfort or injury; and lacks intelligent control and monitoring, and most of them have no parameter adjustment function (such as movement time, speed and massage pressure), and cannot be personalized according to the patient's body size and tolerance; and there is no pressure sensor or other monitoring element, which makes it difficult to avoid the problems of "excessive pressure causing injury" or "insufficient pressure being ineffective".

At the same time, hot water or cold water can also be injected in a targeted manner to apply hot or cold compresses to the patient's legs and feet, so as to achieve the purpose of accelerating local blood circulation and quickly reducing congestion or swelling at the wound, or by constricting blood vessels and reducing blood exudation, thereby achieving the effect of stopping bleeding and relieving pain.

[0044] Specific implementation cases: When using the automatic ankle pump exercise device with foot massage function, the following steps are included: 1. Fixed The patient's feet and calves are placed in the foot fixing seat 3 and the leg fixing sleeve 2 respectively, and fixed by respective fixing belts 36 and restraint belts 24 to prevent the patient's legs and feet from being separated during ankle pump exercise, thereby improving its safety.

[0045] 2. Active exercise The patient can change the angle between the foot fixing seat 3 and the leg fixing sleeve 2 through the movement of his own ankle joint, and the hydraulic resistance mechanism 4 plays a certain obstructive role, ensuring that the autonomous ankle pump movement has a certain training effect.

[0046] 3. Passive exercise The water in the hydraulic chamber 41 can be injected through the water pipe 45 by the first water supply 46, so as to force the hydraulic push rod 42 in the hydraulic chamber 41 to slide downward, and then the cooperation between the lower end of the hydraulic push rod 42 and the connecting plate 31 and the hinged relationship between the hydraulic chamber 41 and the rear side of the upper end of the leg fixing sleeve 2 can make the foot fixing seat 3 deflect clockwise, and when the hydraulic push rod 42 slides to below the second valve port 413, the water in the upper end of the hydraulic chamber 41 will flow into the lower end of the hydraulic chamber 41 through the return pipe 43, and since the valve port of the third valve port 412 is small, the hydraulic push rod 42 will be slowly lifted by the water flowing into the lower end of the hydraulic chamber 41, so as to drive the foot fixing seat 3 to deflect counterclockwise, until the foot fixing seat 3 is lifted above the second valve port 413, and then the above-mentioned action is repeated, and the reciprocating deflection of the foot fixing seat 3 can drive the patient to continuously perform the ankle pump exercise.

[0047] 4. Massage When the patient performs the ankle pump exercise, the eccentric rocker mechanism 9 will drive the eccentric rod 92 to rotate through the second driving part 91, and then the piston plate 93 will be driven to reciprocate in the extrusion area 52 along the movement track of the displacement groove plate 94 by the connecting column 931 hinged to the free end of the eccentric rod 92, so that the water bag 53 is repeatedly extruded, and then the water bag 53 is repeatedly filled with water or restored by water through the first water pipe 23 and the second water pipe 35, so as to repeatedly extrude the water bag block 211 inside the leg fixing sleeve 2 and the foot massage water bag 32 inside the foot fixing seat 3, so as to achieve the massage effect on the legs and feet of the patient.

[0048] During the massage process, hot water and cold water in the hot water area 61 and the cold water area 62 in the lower water tank 6 can be injected into the water bag 53 through the water supply assembly 7 to adjust the water temperature during the massage process and improve the comfort, or hot water or cold water can be injected into the water bag 53 respectively, so that the hot compress or cold compress effect can be achieved by injecting hot water or cold water into the water bag block 211 and the foot massage water bag 32. The above specific embodiments further illustrate the purpose, technical solutions and advantages of the present application, and it should be understood that the above is only a specific embodiment of the present application and is not used to limit the protection scope of the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
