Embodiment 1

[0099] see Figure 1-6 As shown, this embodiment introduces a thrombosis prevention device that can significantly activate the muscles of the lower limbs of the human body to promote blood flow, and does not interfere with the normal state of muscles and pulses. , The thrombosis prevention device includes a base, a rotating shaft support component, a crank slider mechanism, a pedal and an adjustment mechanism (including the first adjustment mechanism 10 and / or the second adjustment mechanism 13). in, figure 1 A schematic diagram of a three-dimensional structure of a thromboprophylaxis device provided in this embodiment; figure 2 A side view of a thromboprophylaxis device provided in this embodiment; image 3 for along figure 2 The cross-sectional view of A-A direction in the middle; Figure 4 A schematic diagram of the three-dimensional structure of a thrombosis prevention device provided in this embodiment when the bottom plate 12 and the base 1 form a certain angle; ...

Embodiment 2

[0117] Figure 7 with Figure 8 Another thromboprophylaxis device is shown. Compared with the thrombosis prevention device in Embodiment 1, the difference is that the height adjustment positioning groove 3 on the base 1 in Embodiment 1 is replaced by several height adjustment positioning holes 3' arranged at intervals along the length direction of the base 1, and other The structure is similar, so the description will not be repeated. In this embodiment, the supporting plate structure also includes a first supporting plate and a top fixing plate and a bottom fixing plate hinged at both ends of the first supporting plate, and the top fixing plate may be fixed to the In the middle part of the bottom surface of the box body 8 of the rotary shaft supporting part, the bottom fixing plate is connected with any height adjustment positioning hole 3' on the base 1 through bolt and nut fasteners 19, and the height adjustment positioning hole 3' is connected with The support plate str...

Embodiment 3

[0119] Figure 9 A third thromboprophylaxis device of the present invention is shown. Compared with the thrombosis prevention device in Embodiment 1, the difference is that the first adjusting mechanism 10 in Embodiment 1 is replaced by an electric push rod mechanism 10', and other structures are basically the same, so the description will not be repeated.

[0120] Such as Figure 9 As shown, in this embodiment, the electric push rod mechanism 10' includes a drive motor 101 and a push rod 102, the drive motor 101 can be installed on the surface near the right end of the base 1, and the push rod 102 Installed obliquely on the drive motor 101, the free end of the push rod 102 is installed in the middle of the bottom surface of the box body 8, so that the drive motor 101 can push the push rod 102 to move to adjust the distance between the box body 8 and the base 1 angle, in order to achieve the purpose of adjusting the distance between the crank shaft 9 and the base 1 of the ba...

Abstract

The invention discloses a thrombus prevention device which comprises a base; a rotating shaft supporting part, wherein one end of the rotating shaft supporting part is rotationally connected with the first end of the base; a crank sliding block mechanism, which comprises a crank rotating shaft, a crank, a sliding or rotating part and a connecting rod, wherein one end of the connecting rod is rotationally connected with one end of the crank, the other end of the connecting rod is rotationally connected with one end, away from the base, of the sliding or rotating part, the crank rotating shaft is rotationally installed at the other end of the rotating shaft supporting part, the other end of the crank is fixedly connected with one end of the crank rotating shaft and the sliding or rotating part and the base form a sliding pair or a higher pair; a pedal, wherein the pedal is mounted on one side, far away from the base, of the connecting rod; and a first adjusting mechanism that is arranged between the rotating shaft supporting part and the base. The thrombus prevention device can obviously activate movement of muscles at all positions of the lower limbs of the human body to promote blood flow, and has the advantages that normal states of muscles and pulses are not interfered with, the shape is adjustable to meet different requirements, and the movement rule of ankle joints of the human body is met.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a thrombosis prevention device. Background technique [0002] At present, venous thromboembolism is a common complication after surgery. In severe cases, it can significantly affect the quality of life and even cause death. The prevention of venous thrombosis in my country is gradually receiving attention. Effective prevention can significantly reduce the incidence of venous thrombosis, thereby reducing mortality. At present, the mainstream methods of physical prevention commonly used in clinical practice include antithrombotic gradient pressure belt, intermittent inflation and compression, and electrical stimulation of muscles. [0003] Improper use of antithrombotic gradient pressure belts on the market may cause skin irritation and rupture, leg edema, and may also produce a "tourniquet effect" that is prone to arterial ischemia or venous return. Some external pressur...
