[0002] With the increasing aging of society and the large number of elderly people, those who are bedridden for a long time and patients are prone to foot pressure injuries, foot drop, and other conditions. Foot drop is often accompanied by symptoms of foot eversion, requiring the use of multiple pressure-relieving pads and orthotic devices at the same time.

[0003] In the prior art, Chinese utility model patent CN214968131U discloses a pressure-reducing pad for preventing foot drop. This pad suspends the heel within a heel groove, reducing pressure on the heel and thus reducing foot pressure and preventing pressure injuries. It also places the sole of the foot against a foot support pad to prevent foot drop. An outer baffle provides support and prevents the patient's lower limb from slipping off the pad. However, for patients already experiencing foot drop, the plantar flexion angle varies, making it impossible to directly support the sole with a vertical baffle. Furthermore, existing foot drop prevention devices cannot be used for rehabilitation exercises. Summary of the Invention

[0004] The purpose of this utility model is to provide a multifunctional foot pressure relief pad, which solves the technical problems of existing pressure relief pads where the foot support angle cannot be adjusted and rehabilitation exercises cannot be performed.

[0005] This utility model discloses a multifunctional foot pressure relief pad, comprising a base. The upper side of the base has symmetrically arranged horizontal arc-shaped grooves running forward and backward. The rear end of each arc-shaped groove is connected to a vertically penetrating through hole in the base.

An arc-shaped block 301 is fixedly arranged on the front side of the rear baffle 3, extending into the cavity. A first ratchet 302 is arranged on the upper side of the arc-shaped block 301. A rotating block 201 is arranged inside the cavity. The rotating block 201 is rotatably connected to the side baffle 2 via a pin. A second ratchet 202 is provided on the lower rear side of the rotating block 201. When the first ratchet 302 and the second ratchet 202 are engaged, the rear baffle 3 is restricted from rotating backward. A first boss 203 is provided on the upper front side of the rotating block 201, and a second boss 204 is provided on the upper rear side of the rotating block 201. An elongated hole 206 is provided on the upper side of the side baffle 2. A sliding block 205 is provided in the elongated hole 206. A sliding groove 207 is provided on the side wall of the elongated hole 206. A protrusion 208 is provided on the side of the sliding block 205. The protrusion 208 is embedded in the sliding groove 207. The height of the bottom of the sliding block 205 is flush with the height of the first boss 203. The second boss 204 is higher than the first boss 203.

[0021] Furthermore, the upper front part of the base 1 is provided with an inclined surface 101, and the arc-shaped groove 102 is provided on the upper part of the inclined surface 101.

[0022] Furthermore, a torsion spring is provided between the rotating block 201 and the side baffle 2, and the torsion spring biases the rear end of the rotating block 201 downward.

[0023] Furthermore, a tension spring 303 is connected between the rear side of the side baffle 2 and the rear baffle 3, and the tension spring 303 biases the rear baffle 3 forward.

[0024] Furthermore, the side of the arc-shaped block 301 is provided with scale lines 304.

[0025] Furthermore, the upper side of the base 1 is provided with a T-shaped groove 104 in the front-to-back direction, and the bottom of the side baffle 2 is provided with a T-shaped block 209 that cooperates with the T-shaped groove 104. The T-shaped groove 104 is connected to the rear side of the base 1, and a stop block 105 is rotatably provided on the rear side of the base 1. A protruding blocking part 108 is provided on the rear side of the base 1 below the T-shaped groove 104.

[0026] Furthermore, the upper side of the side baffle 2 is provided with an elongated hole 206, the length direction of the elongated hole 206 is the front-to-back direction, the left and right side walls of the elongated hole 206 are provided with sliding grooves 207, the sliding block 205 is provided through the elongated hole 206, and the side of the sliding block 205 is provided with a protrusion 208, which is embedded in the sliding groove 207.

[0027] Furthermore, the base 1 is provided with a first fixing strap 106 on the outside of the arc-shaped groove 102.

[0028] Furthermore, the base 1 is provided with second fixing straps 107 on its left and right sides.

[0029] When using this invention, medical staff or family members of the patient need to operate the pressure-relief pad. Place the base 1 at the foot of the bed. First, move the sliding block 205 forward. The bottom of the sliding block 205 presses down on the second protrusion 204 of the rotating block 201, causing the rear end of the rotating block 201 to lift upwards. The second ratchet 202 disengages from the first ratchet 302. Flip the rear baffle 3 backwards, and then move the sliding block 205 backwards. The bottom of the sliding block 205 presses down on the second protrusion 204, causing the second ratchet 202 to engage with the first ratchet 302. Since the bottom height of the sliding block 205 is flush with the height of the first protrusion 203, when the sliding block 205 moves above the first protrusion 203, the front end of the rotating block 201 has no... The method involves lifting the foot, thereby locking the rotation of the arc-shaped block 301 in both forward and backward directions, and locking the rear baffle. Then, the patient's heel is placed above the through hole 103, with the sole facing backward. The sliding block 3 is then moved forward, moving above the first protrusion 203, allowing the rear baffle 3 to flip forward. After adjusting the rear baffle 3 to the position of the patient's sole, the sliding block 205 is moved above the second protrusion 204. The rear baffle 3 can be manually flipped to apply pressure to the patient's sole for foot drop exercises. Alternatively, the angle of the rear baffle 3 can be adjusted to the desired position, applying pressure to the patient's sole, and then the sliding block 205 can be pushed backward to lock the rear baffle 3, correcting foot drop. This invention, through the engagement of the first ratchet 302 and the second ratchet 202 at different positions, can be applied to patients with different degrees of plantar flexion and foot drop.

[0030] A torsion spring (not shown in the figure) is provided between the rotating block 201 and the side baffle 2 to offset the rear side of the rotating block 201 downward. When the sliding block 205 is located between the first boss 203 and the second boss 204, the first ratchet 302 is pushed towards the second ratchet 202, so that the rear baffle 3 can be flipped backward but cannot be flipped forward. This is suitable for operations that require adjustment of angle and increase of plantar pressure.

[0031] The tension spring 303 biases the rear baffle 3 forward. When the sliding block 205 presses against the second protrusion 204 and the first ratchet 302 separates from the second ratchet 202, the rear baffle 3 can automatically return to its forward position, making it easy to quickly adjust the angle.

[0032] The scale line 304 is set to facilitate accurate adjustment of the angle of the rear baffle 3, and the patient's plantar flexion angle can also be measured and recorded through the scale line 304.

[0033] A sliding block 205 is disposed within an elongated hole 206, with its top extending out of the hole for manual operation. The elongated hole 206 extends longitudinally, allowing the sliding block 205 to move back and forth, facilitating its bottom to press against different positions on the rotating block 201. Slide grooves 207 are provided on the left and right sidewalls of the elongated hole 206, and protrusions 208 are provided on the left and right sides of the sliding block 205. These protrusions 208, embedded in the slide grooves 207, guide the sliding block 205, enabling its translation.

[0034] The side baffle 2 engages with the T-slot 104 via a T-block 209, allowing the side baffle 2 to slide and be disassembled. The stop block 105 is rotatably connected to the rear side of the base 1 via a pin located outside the T-slot 104. After the side baffle 2 is installed, rotating the stop block 105 blocks it from the outside of the T-block 209, preventing the side baffle 2 from coming off. The blocking part 108 limits the stop block 105, ensuring it is accurately blocked from the outside of the T-block 209. After removing the side baffle 2, the base 1 can be used as a regular pressure-relief pad, with the patient's heel placed at the through-hole for foot pressure relief.

[0035] The first fixing strap 106 can fix the patient's foot and further prevent the heel from moving forward when the rear baffle 3 presses against the bottom of the foot. The second fixing strap 107 can be tied to the bed to fix the base 1 at the foot of the bed and prevent the pressure relief pad from moving back and forth when in use.
