[0002] In order to effectively prevent the occurrence of venous thrombosis, it is essential to exercise the feet regularly. For people with limited mobility, passive foot training is particularly important. Traditional foot training is usually limited to massaging the foot muscles, but when massaging the foot, the activity of the leg muscles cannot be ignored to prevent poor blood circulation in the legs, which affects the effect of foot massage. Current technology can only massage the feet in fixed positions, while there are many acupoints in the feet and legs and their locations are different, so different ranges of massage are required for the feet and legs. Based on this, we propose a foot passive trainer for preventing venous thrombosis. Summary of the invention

[0026] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] With the improvement of living standards, people's lives have become more comfortable and easy. However, the existing health problems of the lower limbs are becoming more and more serious. Among them, the health of the feet is often neglected and eventually develops into serious diseases.

[0028] A foot passive trainer for preventing venous thrombosis comprises a fixing frame 1 and a collecting box 11, wherein a stretching structure 2 for exercising a patient's legs is arranged on the top of the fixing frame 1, a massage structure 3 for preventing venous thrombosis in the patient's feet is arranged on the top of the collecting box 11, and an adjustment structure 4 for massaging the patient to different degrees is arranged on the top of the collecting box 11;

[0029] When the stretching structure 2 stretches the patient's legs, it drives the massage structure 3 to swing on the top of the collection box 11. At the same time, when the stretching structure 2 moves, it drives the adjustment structure 4 and the massage structure 3 to swing in the opposite direction, so that when the massage structure 3 and the adjustment structure 4 move, the patient's leg muscles are stretched to different degrees at different positions, and when the stretching structure 2 moves, it presents a different swing amplitude with the massage structure 3, and the patient's feet are lifted to different heights.

[0030] The present invention takes into account that when existing devices are used to prevent foot venous thrombosis, the existing devices usually only massage the soles of the patients' feet. During a long massage process, the patient's leg muscles also need to be massaged synchronously. The massage of the leg muscles helps promote blood circulation and increase the speed of blood returning to the heart. In addition, during the process of foot massage by existing devices, since there are many acupuncture points on the feet, the acupuncture points on the feet need to be massaged in different ranges. The present invention stretches the patient's legs during exercise through the stretching structure 2, and drives the patient's heel to slide in the wave groove opened above the massage ring 34. After the stretching structure 2 moves to a certain position, the position between the massage structure 3 and the adjustment structure 4 is adjusted, so that the massage ring 34 can swing with different amplitudes to massage different acupuncture points on the patient's heel, leg and sole.

[0031] In the above embodiments, the following specific structures need to be disclosed in detail:

[0032] For the normal operation of the device, the fixing frame 1 is fixedly connected to the collection box 11, a sealing door is installed on one side of the collection box 11, a motor 13 is installed inside the collection box 11, and four support columns 1201 are rotatably connected to the top of the fixing frame 1, and the ends of the four support columns 1201 away from the fixing frame 1 are fixedly connected to the seats 12;

[0033] In order to stretch the patient's legs, the stretching structure 2 includes a cam 21 fixedly connected to the output shaft end of the motor 13, the output shaft end of the motor 13 penetrates the outer wall of the motor 13, the output shaft end of the motor 13 is rotatably connected to the motor 13, the side of the cam 21 away from the motor 13 is rotatably connected to the swing rod 22, the upper side of the swing rod 22 away from the cam 21 is rotatably connected to the sliding block 23, the two sides of the sliding block 23 are respectively slidably connected to two limit blocks 2301, the two limit blocks 2301 are fixedly connected to the upper surface of the fixing frame 1, the upper surface of the sliding block 23 away from the swing rod 22 is fixedly connected to a rectangular block 24, and the rectangular block 24 is slidably connected to the two limit blocks 2301;

[0034] Specifically, by providing the two limit blocks 2301 , the sliding block 23 and the rectangular block 24 can slide back and forth above the fixing frame 1 .

[0035] The two sides of the rectangular block 24 away from the sliding block 23 are respectively fixedly connected with cylinders 25, the outer side of the cylinder 25 is rotatably connected with a connecting block 26, the middle part of the connecting block 26 is rotatably fixedly connected to the support column 1201, the side of the connecting block 26 away from the rectangular block 24 is fixedly connected with a connecting plate 27, and the side of the connecting plate 27 away from the connecting block 26 is fixedly connected with a special-shaped block 28;

[0036] Specifically, when the device is used, the medical staff places the patient's buttocks above the seat 12. After the patient's buttocks are placed above the seat 12, the medical staff places the patient's legs inside the special-shaped block 28, and then starts the motor 13. After the motor 13 is started, it drives the cam 21 fixedly connected to its output shaft end to rotate. The rotation of the cam 21 drives the swing rod 22 connected to the rotation to swing. When the swing rod 22 swings, it drives the sliding block 23 connected to the rotation to slide back and forth inside the two limit blocks 2301. The sliding block 23 also drives the rectangular block 24 to slide. When the rectangular block 24 slides, it drives the connecting block 26 to reciprocate around the support column 1201 fixedly connected to the middle thereof through the cylinder 25. When the connecting block 26 rotates, it drives the special-shaped block 28 to rotate through the connecting plate 27. When the special-shaped block 28 rotates, it drives the patient's legs to rotate, thereby stretching the patient's legs.

[0037] In order to massage the patient's heels and soles, the massage structure 3 includes two wedge blocks 31, the two wedge blocks 31 are fixedly connected to the connecting plate 27, a sliding body 32 is attached to the side of the two wedge blocks 31 away from the seat 12, a fixed plate 3201 is fixedly connected to the bottom of the sliding body 32, the fixed plate 3201 is slidably connected to the collection box 11, two first bosses 33 are fixedly connected to the side of the sliding body 32 away from the wedge blocks 31, and two massage rings 34 are respectively attached to the side of the two first bosses 33 away from the sliding body 32.

[0038] In order to massage the sole and heel of the patient in different ranges, the two massage rings 34 are respectively fixedly connected with connecting shafts 3401 near the inside of the wedge block 31, and the connecting shaft 3401 is rotatably connected to the collection box 11. The two first protrusions 33 are located on the side of the connecting shaft 3401 close to the sliding body 32. The top of the collection box 11 is fixedly connected with a massage sheet 35. The upper part of the two massage rings 34 is provided with a wave groove, and the side of the massage sheet 35 close to the seat 12 is equipped with a plurality of massage balls.

[0039] Specifically, when the patient's legs are placed inside the special-shaped block 28, the patient's heels are placed inside the wave groove above the massage ring 34 by medical staff, and the patient's heels are placed in close contact with the massage ball installed on the massage sheet 35 near the side of the seat 12. At this time, when the connecting plate 27 drives the special-shaped block 28 to swing, the patient's heels will move up and down around the root of the leg along the wave groove, and at the same time, the sole of the patient's foot will contact the massage ball installed on the connecting shaft 3401 to massage the patient's heels;

[0040] The patient's heel is massaged while the patient's heel moves up and down, so that the massage ball and the patient's heel can perform a large-scale massage, thereby avoiding a single massage position and reducing the effect of massaging the patient's heel.

[0041] refer to Figure 4 and Figure 5When the two connecting plates 27 swing around the support column 1201 toward the side close to the seat 12, the two connecting plates 27 drive the wedge blocks 31 fixedly connected thereto to swing, so that the two wedge blocks 31 on the side away from the seat 12 synchronously squeeze the sliding body 32 on the side close to the seat 12, so that the sliding body 32 slides toward the side away from the seat 12. When the sliding body 32 slides, it drives the sliding body 32 fixedly connected thereto to slide toward the side away from the seat 12. When the first protrusion 33 slides, it will squeeze the massage ring 34 on the side close to the seat 12, so that the massage ring 34 rotates clockwise around the connecting shaft 3401.

[0042] When the two special-shaped blocks 28 swing toward the side away from the seat 12, the wedge block 31 does not squeeze the sliding body 32, and the sliding body 32, the first protrusion 33 and the massage ring 34 do not continue to move. At this time, the massage ring 34 completes its swing, and the special-shaped block 28 drives the patient's legs to move. The contact range distance between the massage ring 34 and the patient's legs on the side away from the connecting shaft 3401 will gradually move toward the direction close to the patient's thigh, thereby massaging different positions of the patient's legs. Because the contact position between the massage ring 34 and the patient's legs on the side away from the connecting shaft 3401 is different, the position of the wave groove of the patient's legs above the massage ring 34 will also be different, and the swing amplitude of the patient's legs around the roots of the legs will also increase. At this time, when the patient's legs swing along the wave groove above the massage ring 34, the swing amplitude of the patient's heels above the massage ring 34 will increase.

[0043] In order to adjust the massage range of the patient's sole and heel, the adjustment structure 4 includes a sliding rod 41 that is in contact with the cam 21, and the end of the sliding rod 41 away from the cam 21 is fixedly connected to a moving block 42, the moving block 42 is slidingly connected to the collection box 11, and the side of the moving block 42 away from the sliding rod 41 is respectively fixedly connected to two second protrusions 43.

[0044] The two second protrusions 43 are respectively fitted with the two massage rings 34 at one side away from the sliding rod 41 , and the two second protrusions 43 are located at the side of the connecting shaft 3401 away from the sliding body 32 .

[0045] Specifically, refer to Figure 5 , Figure 6 and Figure 7 When the connecting plate 27 swings to the maximum angle on the side away from the seat 12, the cam 21 will squeeze the sliding rod 41, so that the sliding rod 41 drives the second boss 43 to slide to the side away from the cam 21 through the moving block 42. At this time, the second boss 43 squeezes the massage ring 34 away from the connecting shaft 3401, so that the massage ring 34 rotates counterclockwise around the connecting shaft 3401.

[0046] Specifically, when the massage ring 34 swings, the first protrusion 33 is squeezed on the top thereof, so that the first protrusion 33 drives the sliding body 32 to slide toward the side away from the massage sheet 35. When the sliding body 32 slides, the side of the sliding body 32 away from the connecting shaft 3401 will be reset. When the two connecting plates 27 swing toward the side close to the seat 12, the connecting plates 27 can drive the wedge block 31 to continue squeezing the sliding body 32.

[0047] When the massage ring 34 rotates counterclockwise around the connecting shaft 3401, the movement process among the massage ring 34, the massage sheet 35 and the wave groove opened above the massage ring 34 will move opposite to the movement process of the above-mentioned stretching structure 2, thereby performing cyclic massage of different degrees and ranges on the patient's heel, leg and heel.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
