For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The specific embodiments are as follows:

[0022] Embodiment 1, as Figure 1-4 As shown, an anti-pressure sore foot protector comprises a support seat 1, a strap 2 and a bottom cushion 3. The support seat 1 is provided with a placement cavity for placing the user's foot and calf. A bottom cushion 3 is provided at the bottom of the support seat 1, and a strap 2 is provided at the opening of the support seat 1. In this embodiment, the bottom cushion 3 is a composite of one or more of cotton pads, water bags, foams, etc. The user's foot and calf are placed in the placement cavity of the support seat 1, with the heel close to the left side wall of the support seat 1, and the foot and calf are supported by the bottom cushion 3. The soft characteristics of the bottom cushion 3 reduce the pressure between the foot and the bottom cushion 3 during support, thereby reducing the occurrence of pressure sores.

[0023] The bottom cushion pad 3 is composed of two parts, which are arranged along the length direction of the placement cavity and are spaced apart. An adjustment slot 31 is formed in the interval between the two parts, and the adjustment slot 31 is located at the user's ankle. An adjustment window 11 is provided on the front and rear side walls of the support seat 1 at a position corresponding to the adjustment slot 31. An ankle support device 5 is provided in the adjustment slot 31. The ankle support device 5 includes a support plate 52 and an ankle pad 51. The horizontal line of the support plate 52 passes through the adjustment slot 31, and its two ends are cantilevered in the adjustment window 11. The ankle pad 51 is fixedly connected to the support plate 52, providing a buffering effect between the support plate 52 and the user's ankle, and avoiding the phenomenon of the ankle being hurt when the support plate 52 supports the user's ankle. In this embodiment, the ankle pad 51 is made of the same material as the bottom cushion pad 3.

[0024] A magnetic suspension assembly 4 is provided at the bottom of the adjustment window 11, which is used to support and adjust the height of the ankle support device 5. The magnetic suspension assembly 4 includes a sleeve 41, a telescopic cylinder 42, an electromagnet 43 and a permanent magnet 44. The sleeve 41 is fixed at the bottom of the adjustment window 11, and the electromagnet 43 is provided at the bottom of the sleeve 41, and the electromagnet 43 is connected to the power supply through a line; the telescopic cylinder 42 is sleeved in the sleeve 41 and can be adjusted up and down, and the top end of the telescopic cylinder 42 is fixed to the bottom surface of the support plate 52 near the end, and the permanent magnet 44 is provided at the top of the telescopic cylinder 42; the magnetic poles of the magnetic field formed by the electromagnet 43 after being energized are arranged relative to the permanent magnet 44.

[0025] In this embodiment, the power supply is arranged on the support base 1, and an on-off switch is arranged between the power supply and the electromagnet 43, so as to facilitate the use of the protective cover without being restricted by the power cord.

[0026] In other embodiments, the power source adopts an external power source, such as alternating current, etc., which is connected to the power source through a power cord extending from the support base, and other structures are not described here.

[0027] In this embodiment, a timer and a controller are also provided on the support seat. The timer and the electromagnet are electrically connected to the controller. The controller receives the time information of the timer, and controls the ankle support device 5 to rise up to support the ankle for a certain period of time after a set time interval. After supporting the set time period, the ankle support device 5 is controlled to descend, so as to support the user's ankle in a gap to adjust the pressure between the user's heel and the bottom cushion pad 3 and reduce the occurrence of pressure sores.

[0028] In other embodiments, the electromagnet is directly connected to the power supply through a circuit, and an on-off switch is provided on the circuit to control whether the power is turned on or not by human control, thereby controlling the lifting and lowering of the ankle support device. Other structures are not described in detail here.

[0029] When using the anti-pressure sore foot protection sleeve of this embodiment, the nursing staff places the user's foot and calf in the placement cavity of the support seat 1 and fixes them with the straps 2 to prevent the user from slipping out of the support seat 1. After the power is turned on, the timer starts timing. When the set time ends in time, the user's foot sinks into a depression on the bottom cushion pad 3 due to long-term immobility. At this time, the pressure between the heel and the bottom cushion pad 3 increases again. At this time, the controller receives the signal of the timer and controls the magnetic suspension component 4 to extend upward, supporting the ankle support device 5 to rise upward, and the support plate 52 supports the ankle, so that the user's heel is raised, reducing the pressure between the heel and the bottom cushion pad 3, thereby reducing the occurrence of pressure sores. After the ankle support device 5 rises, the timer starts counting again. When it ends in time, the controller controls the magnetic suspension component 4 to retract downward, the ankle support device 5 drops, and the user's foot is supported by the bottom cushion 3 again to reduce the discomfort caused by the ankle being supported by the support plate 52 for a long time; at the same time, the setting of the ankle pad 51 on the support plate 52 avoids the phenomenon of hurting the ankle. The ankle support device 5 rises or falls at regular time intervals to adjust the pressure conditions at the heel and ankle, which can effectively prevent the occurrence of foot pressure sores caused by continuous excessive pressure, and has a good prevention effect.

[0030] Furthermore, the outer walls of the sleeve 41 and the telescopic cylinder 42 are coated with a magnetic field shielding layer to shield the internal magnetic field and prevent the magnetic field from affecting some equipment in the user's environment or the user himself.

[0031] In this embodiment, the material of the magnetic field shielding layer can be one of soft magnetic materials (made of metals such as iron, nickel and cobalt), highly conductive materials (such as copper, aluminum and silver, etc.), magnetic composite materials (made by mixing soft magnetic materials and highly conductive materials) and organic materials, and it can also be achieved as a prerequisite for shielding the magnetic field in the magnetic levitation telescopic component from external interference.

[0032] Furthermore, sliders 53 are provided on both sides of the support plate 52 near the end, and slide grooves 111 are provided on the inner side walls of the adjustment window 11. The sliders 53 are suspended into the slide grooves 111, and under the adjustment of the magnetic suspension assembly 4, the sliders 53 slide along the slide grooves 111, playing a guiding role, ensuring that the ankle support device 5 moves up and down in a straight line.

[0033] Furthermore, the middle portion of the support plate 52 is arc-shaped to fit the curvature of a person's ankle, so as to reduce discomfort when supporting the ankle.

[0034] Furthermore, the bottom cushion pad 3 is wedge-shaped, with one end close to the user's heel higher than the other end, so that when supporting the user's foot, the user's foot is lifted to a certain extent, which helps the blood return to the foot.

[0035] Furthermore, a side wall buffer pad (not shown in the figure) is provided on the inner wall of the support seat 1, and its material is the same as that of the bottom buffer pad 3, so as to improve the comfort of use and reduce the possibility of bumps.

[0036] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
