Medical constant-pressure ankle pump device

[0020] Example 1

[0021] Such as Figure 1-3 As shown, a medical constant-pressure ankle pump device includes a base 1. The base 1 is L-shaped, a massage airbag 2 is fixedly connected to the vertical side wall of the base 1, and a horizontal side wall of the base 1 is fixedly connected The squeeze airbag 3, the massage airbag 2 and the squeeze airbag 3 are made of elastic materials such as rubber. The massage airbag 2 corresponds to the position of the sole of the foot, the pressing airbag 3 corresponds to the position of the calf, and the horizontal section and the vertical section of the L-shaped base 1 The junction is recessed downwards to form a groove for accommodating the heel, so that the whole device is matched with the physiological structure of the patient's calf and foot.

[0022] The base 1 is provided with a strip-shaped cavity 4, the strip-shaped cavity 4 is communicated with the massage airbag 2 and the squeezing airbag 3 through the first air pipe 5 and the second air pipe 6, respectively, and the strip cavity 4 is rotatably connected with The permanent magnet column 7 has opposite magnetic poles at both ends. The permanent magnet column 7 is fixedly connected with a rotating shaft 71. The axis of the rotating shaft 71 intersects and is perpendicular to the axis of the permanent magnet column 7. The side wall of the cavity 4 is rotatably connected, the other end of the rotating shaft 71 penetrates the base 1 and is fixedly connected with a rocking handle 72, both sides of the permanent magnet column 7 are provided with a magnetic piston block 8 which is slidably and sealedly connected with the strip cavity 4. The magnetic poles of the opposite sides of the magnetic piston block 8 are in opposite directions. It is worth mentioning that the inner side wall of the strip-shaped cavity 4 is provided with a limiting protrusion 41 for limiting the magnetic piston block 8, and the limiting protrusion 41 is provided Between the permanent magnet column 7 and the magnetic piston block 8, the limiting protrusion 41 can prevent the magnetic piston block 8 from directly contacting the permanent magnet column 7. It should be noted that the bar-shaped void between the two limiting protrusions 41 The side wall of the cavity 4 is provided with air holes communicating with the outside, which can ensure the air pressure balance inside and outside the strip cavity 4.

[0023] When using this embodiment, first place the heel of the patient in the groove, place the calf on the upper side of the squeeze airbag 3, and fit the sole of the foot with the massage airbag 2, and then rotate the crank 72, which drives the permanent magnet column 7 rotates, since the magnetic poles of the opposite sides of the two magnetic piston blocks 8 are in opposite directions, when the permanent magnet column 7 rotates to a state of attracting the opposite poles of the two magnetic piston blocks 8, such as figure 1 As shown, at this time, the air inside the pressing airbag 2 and the squeezing airbag 3 is reduced and deflated; when the permanent magnet column 7 rotates to a state of repelling the two magnetic piston blocks 8 at the same pole, as figure 2 As shown, at this time, the air inside the pressing airbag 2 and the squeezing airbag 3 increases and expands, which can perform ankle pump motion on the sole of the patient to promote blood circulation of the patient, and the squeezing airbag 3 can massage the patient's calf, and further Play a healing effect.

[0024] In the process of use by medical staff or patients’ family members, they only need to continuously rotate the crank 72 in one direction, which is not only simple and convenient, but also can ensure that the pressing airbag 2 and the squeezing airbag 3 exert the same force each time and are operated The influence of factors such as personnel proficiency or strength is small and has strong practicality.

[0025] Example 2

[0026] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that: a multi-turn closed coil 91 is fixedly connected to the side wall of the strip cavity 4, and the winding direction of the closed coil 91 is perpendicular to the rotation direction of the permanent magnet column 7. , When the permanent magnet column 7 is rotating, the magnetic induction line of the permanent magnet column 7 can cut the closing coil 91 to move, so that the induction current is generated in the closing coil 91, and an electric heating plate 92 is provided in the extrusion airbag 3, and the electric heating plate 92 is fixedly installed At the upper end of the base 1, an electric heating plate 92 is coupled and connected in a loop formed by a closed coil 91.

[0027] In this embodiment, when the permanent magnet column 7 continues to rotate, the magnetic induction line of the permanent magnet column 7 can cut the closing coil 91, so that an induced current is generated in the closing coil 91 and the electric heating plate 92 is supplied with power, thereby being able to compress The airbag 3 is heated, and then the squeeze airbag 3 is used to heat the position of the patient's calf, which can further promote blood circulation and accelerate recovery.
