Description

Technical Field

[0001] The present invention belongs to the technical field of rehabilitation equipment, and relates to an auxiliary exercise device and a control method for early postoperative rehabilitation of patients with craniocerebral trauma. Background Art

[0002] Craniotomy, also known as craniotomy, is a type of cranial surgery. It refers to opening the patient's skull through mechanical equipment to perform some unconventional treatments to achieve the purpose of curing the disease. After the operation, the patient needs to lie on the nursing bed to rest, and the doctor will check the patient's recovery regularly until the wound heals and the patient can move normally.

[0003] Patients with severe craniocerebral trauma need to stay in bed for a long time, their movement is restricted, and they are prone to complications such as deep vein thrombosis and pressure sores, which seriously affect the recovery process. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary exercise device and control method for early postoperative rehabilitation of patients with craniocerebral trauma, which guides the patient's lower limbs to automatically perform ankle pump exercises to prevent deep vein thrombosis.

[0005] In order to achieve the above-mentioned object, the basic scheme of the present invention is: an auxiliary exercise device for early rehabilitation of patients with craniocerebral trauma after surgery, comprising a bed, and a surrounding mechanism and a flexion and extension mechanism arranged on both sides of the bed;

[0006] The surrounding mechanism includes a bracket, a telescopic rod, a power source and a rotating rod. The bracket is detachably connected to the foot side of the bed body. One end of the telescopic rod is connected to the bracket, and the other end of the telescopic rod is connected to the power source. The rotating shaft of the power source is connected to one end of the rotating rod. The rotating rod is perpendicular to the rotating shaft of the power source. A clamping part is installed on the end of the rotating rod away from the power source, and the patient's toes are clamped with the clamping part.

[0007] The flexion and extension mechanism includes a rotating plate, a cylinder and an airbag. One side of the rotating plate is hingedly connected to the tail of the bed, and the rotating plate is connected to a first rotating mechanism that controls its rotation. A baffle is provided on the peripheral side of the rotating plate away from the first rotating mechanism. The cylinder is arranged on the side of the rotating plate, and a magnetic ring is provided on the piston in the cylinder. A permanent magnet attracted to the magnetic ring is provided on the side of the rotating plate away from the first rotating mechanism. The airbags are respectively arranged on the side of the rotating plate in contact with the patient's foot and on the baffle opposite to it. A card block is provided on the outer surface of the airbag, and a number of card slots arranged in sequence are provided on the rotating plate and the baffle connected to the airbag. Gas is built into the cylinder, and the top of the cylinder is connected to the airbag on the rotating plate, and the bottom of the cylinder is connected to the airbag on the baffle.

[0008] The working principle and beneficial effect of this basic solution are as follows: This technical solution sets two mechanisms on the bed, which is convenient for patients to exercise while lying in bed. The bracket surrounding the mechanism is detachably connected to the bed, which is convenient for disassembly and adjustment of position.

[0009] The telescopic rod's ends are connected to the bracket and power source, respectively. The power source controls the rod's circular rotation. The patient's toes engage the clamping portion of the rod, and the shaft rotates, driving the patient's foot in a circular motion, guiding the patient's ankle joint to automatically rotate 360°. The telescopic rod is retractable to adjust its length, controlling the distance between the rod and the patient's foot to accommodate different foot lengths.

[0010] The rotating plate is located at the foot of the bed and is controlled by a first rotating mechanism. During use, the sole of the patient's foot contacts the rotating plate, which rotates to flex the patient's foot toe and dorsiflexion. Baffles are placed around the area where the rotating plate contacts the patient's toes. The patient's foot extends into the space enclosed by the baffles, which initially restrain the patient.

[0011] The airbags are located on the side of the rotating plate that contacts the patient's foot and on the baffle facing it. The airbags are inflated and deflated sequentially in conjunction with the movement of the piston in the cylinder. A magnetic ring is attached to the piston in the cylinder, and a permanent magnet is mounted on the rotating plate. This creates a magnetic attraction between the two. When the rotating plate rotates, the permanent magnet moves, causing the magnetic ring to move linearly upward or downward within the cylinder.

[0012] When the rotating plate rotates upward, the patient performs dorsiflexion exercise, and the permanent magnet on the rotating plate moves upward accordingly. The magnetic ring on the piston in the cylinder moves upward under the magnetic attraction of the permanent magnet, pushing the gas above the piston in the cylinder into the airbag on the rotating plate. The airbag gradually expands, lifting the toes of the patient's foot, ensuring that the patient's toes are fully dorsiflexed during dorsiflexion exercise, thereby ensuring the dorsiflexion effect.

[0013] When the rotating plate flips downward, the patient performs toe flexion exercise, and the permanent magnet on the rotating plate moves downward accordingly. The magnetic ring on the piston in the cylinder moves downward under the magnetic attraction of the permanent magnet, pushing the gas under the piston in the cylinder into the airbag on the baffle. The airbag gradually expands, pressing down the position of the patient's foot toes, ensuring that the patient's toes are fully straightened during toe flexion exercise, thereby ensuring the toe flexion effect.

[0014] At the same time, the space above the piston in the cylinder increases to form negative pressure, which draws the gas in the airbag on the rotating plate into the cylinder, causing the airbag on the rotating plate to shrink without affecting the patient's toe flexion movement. Similarly, when the rotating plate flips upward, the airbag on the baffle also shrinks.

[0015] The airbag is provided with a card block, which can be engaged with the card slots at different positions on the corresponding connected rotating plate and baffle, thereby adjusting the position of the airbag so that it can be aligned with the toes of different patients, ensuring that it can adapt to patients with different foot lengths and has a wide range of uses.

[0016] Furthermore, it also includes a turning mechanism, which includes a first bed board, a second bed board and a massage ejector;

[0017] The first bed board and the second bed board are arranged side by side on the bed body, and the adjacent sides of the two are respectively hinged to the bed body for rotation, and are correspondingly connected to a second rotation mechanism for controlling the independent rotation of the first bed board and the second bed board;

[0018] The first bed board and the second bed board are provided with a plurality of grooves, the massage ejectors are placed in the grooves, and the massage ejectors are connected to a telescopic mechanism for controlling the extension and retraction of the massage ejectors.

[0019] Two bed boards are set up. When one side needs to turn over, the second rotating mechanism connected to the first bed board or the second bed board is controlled to start, and the corresponding bed board is controlled to flip over, thereby driving the patient on it to turn over, realizing turning over training, and also preventing pressure sores.

[0020] The bed is also equipped with grooves and ejectors. A telescopic mechanism controls the intermittent ejection of the ejectors to massage the patient's back. If one ejector is ejected, the patient's back can be tilted at a small angle to prevent pressure sores.

[0021] Furthermore, the connecting rod includes rod one and rod two, one end of rod one is connected to the power source, and the other end is provided with a threaded hole, one end of rod two extends into the threaded hole of rod one and is threadedly connected to the threaded hole, and the clamping part is sleeved on rod two.

[0022] The connecting rod, constructed through rods 1 and 2, allows for adjustable length, changing the size of the patient's toe circles, allowing for multiple-size circle training for enhanced effectiveness. The clamping portion is directly attached to rod 2, allowing for manual adjustment of the clamping portion as the threaded rods 2 and 1 rotate, providing flexibility.

[0023] Furthermore, the surrounding mechanism further includes a rotating shaft and a plurality of connecting holes;

[0024] The rotating shaft is fixedly connected to one end of the telescopic rod, and the rotating shaft is perpendicular to the telescopic rod;

[0025] The connecting holes are arranged at different height positions of the bracket, an internal thread is arranged in the connecting hole, an external thread is arranged on the outer wall of the rotating shaft, and the rotating shaft can be threadedly connected to the connecting hole.

[0026] The rotating shaft is threadedly connected to the connecting holes at different heights on the bracket, and the height position of the telescopic rod can be adjusted to adapt to patients with different foot lengths. It is easy to disassemble and assemble.

[0027] Furthermore, it also includes an arc-shaped positioning recess, which is arranged on the bed body and is located on the side of the human body facing the rotating plate, and an elastic protective layer is provided on the inner wall of the positioning recess.

[0028] The positioning recess is designed to facilitate positioning when the patient's heel is placed in the positioning recess during ankle pump exercises. The elastic protective layer contacts the patient for increased comfort.

[0029] Furthermore, it also includes a pressure sensor and a display module. The pressure sensor is arranged on the side of the rotating plate that contacts the patient's foot. The output end of the pressure sensor is connected to the input end of the display module. The display module is installed on the side of the bed.

[0030] The pressure sensor collects the pressure signal between the sole of the patient's foot and the rotating plate and transmits it to the display module for easy viewing, so as to judge the contact between the patient's foot and the rotating plate, and whether the pressure between the patient's foot and the rotating plate is appropriate when the patient's foot moves.

[0031] The present invention also provides a control method for the device of the present invention, comprising the following steps:

[0032] Collect the pressure signal between the rotating plate and the patient's foot;

[0033] The first rotating mechanism controls the rotating plate to perform plantar flexion and dorsiflexion movements in a first amplitude;

[0034] During plantar flexion, the pressure sensor on the sole of the rotating board detects the plantar flexion pressure P1. During dorsiflexion, the pressure sensor on the sole of the rotating board detects the dorsiflexion pressure P2. The higher value of the plantar flexion pressure P1 and the dorsiflexion pressure P2 is determined, and the movement corresponding to the higher value is used as the test movement. The rotation amplitude of the rotating board is determined when the test movement reaches the pressure threshold.

[0035] Perform plantar flexion and dorsiflexion movements within this range of rotation.

[0036] According to the collected pressure signals, the rotation amplitude is dynamically adjusted to adapt it to the patient's exercise needs, resulting in better rehabilitation training effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention discloses an auxiliary exercise device for early postoperative rehabilitation of patients with craniocerebral trauma. Figure 1 As shown, it includes a bed body 8, and a surrounding mechanism and a flexion and extension mechanism arranged on both sides of the bed body 8.

[0044] The encircling mechanism includes a bracket 1, a telescopic rod 2, a power source 3, and a rotating rod 4. The bracket 1 is detachably connected to the foot of the bed body 8, such as by providing a snap connection, or by providing threaded holes in different positions for screw connection. One end of the telescopic rod 2 (which can adopt an existing adjustable telescopic rod 2 structure) is connected to the bracket 1, and the other end of the telescopic rod 2 is connected to the power source 3 (such as by bonding, welding, riveting, etc.). The power source 3 is a motor. The rotating shaft of the power source 3 is connected to one end of the rotating rod 4 (such as by welding, bonding, pin connection, etc.). The rotating rod 4 is perpendicular to the rotating shaft of the power source 3. The end of the rotating rod 4 away from the power source 3 is equipped with a clamping portion 10 (such as a slot made of rubber, sponge, etc., or an elastic band, etc.), and the patient's toes are clamped to the clamping portion 10.

[0045] The flexion and extension mechanism includes a rotating plate 5, a cylinder 6 and an airbag 7. One side of the rotating plate 5 is hinged to the tail of the bed 8. The rotating plate 5 is connected to a first rotating mechanism that controls its rotation. A baffle 9 is provided on the peripheral side of the rotating plate 5 away from the first rotating mechanism. Figure 2 As shown, the cylinder 6 is arranged on the side of the rotating plate 5. The piston in the cylinder 6 is provided with a magnetic ring. A permanent magnet that attracts the magnetic ring is provided on the side of the rotating plate 5 away from the first rotating mechanism. The airbags 7 are respectively provided on the side of the rotating plate 5 that contacts the patient's foot and on the baffle 9 directly opposite. The outer surface of the airbags 7 is provided with a locking block. The rotating plate 5 and the baffle 9 to which the airbags 7 are connected are provided with a plurality of slots arranged in sequence. The cylinder 6 contains gas. The top of the cylinder 6 is connected to the airbag 7 on the rotating plate 5, and the bottom of the cylinder 6 is connected to the airbag 7 on the baffle 9.

[0046] During use, the power source 3 is activated, which controls the rotating rod 4 to rotate in a circular motion. The patient's toes engage the clamping portion 10 on the rotating rod 4. The rotating shaft rotates, driving the patient's foot in a circular motion, guiding the patient's ankle joint to automatically move 360 ​​degrees. The telescopic rod 2 is retractable to adjust its length, controlling the distance between the flexible rotating rod 4 and the patient's foot to accommodate different foot lengths.

[0047] A rotating plate 5 is positioned at the foot of the bed and is controlled by a first rotating mechanism. During use, the sole of the patient's foot contacts the rotating plate 5, which rotates to flex the patient's foot toe and dorsiflexion. A baffle 9 is positioned around the area where the rotating plate 5 contacts the patient's toes. The patient's foot extends into the space enclosed by baffle 9, which serves as a preliminary restraint.

[0048] Airbag 7 is mounted on the side of rotating plate 5 that contacts the patient's foot and on the opposing baffle 9. The airbag 7 is inflated and deflated sequentially in conjunction with the movement of the piston in cylinder 6. A magnetic ring is attached to the piston in cylinder 6, and a permanent magnet is mounted on rotating plate 5. This creates a magnetic attraction between the two. When rotating plate 5 rotates, causing the permanent magnet to move, the magnetic ring moves linearly upward or downward within cylinder 6.

[0049] When the rotating plate 5 rotates upward, the patient performs dorsiflexion exercise, and the permanent magnet on the rotating plate 5 moves upward accordingly. The magnetic ring on the piston in the cylinder 6 moves upward under the magnetic attraction of the permanent magnet, pushing the gas above the piston in the cylinder 6 into the airbag 7 on the rotating plate 5. The airbag 7 gradually expands, lifting the toes of the patient's foot, ensuring that the patient's toes are fully dorsiflexed during dorsiflexion exercise, thereby ensuring the dorsiflexion effect.

[0050] When the rotating plate 5 flips downward, the patient performs toe flexion exercise, and the permanent magnet on the rotating plate 5 moves downward accordingly. The magnetic ring on the piston in the cylinder 6 moves downward under the magnetic attraction of the permanent magnet, pushing the gas under the piston in the cylinder 6 into the airbag 7 on the baffle 9. The airbag 7 gradually expands, pressing down the position of the patient's foot toes, ensuring that the patient's toes are fully straightened during toe flexion exercise, thereby ensuring the toe flexion effect.

[0051] At the same time, the space above the piston in the cylinder 6 increases to form a negative pressure, which draws the gas in the airbag 7 on the rotating plate 5 into the cylinder 6, causing the airbag 7 on the rotating plate 5 to shrink without affecting the patient's toe flexion movement. Similarly, when the rotating plate 5 turns upward, the airbag 7 on the baffle 9 also shrinks.

[0052] The airbag 7 is provided with a card block, which can be engaged with the card slots at different positions on the corresponding connected rotating plate 5 and the baffle 9, thereby adjusting the position of the airbag 7 so that it can be aligned with the toes of different patients, ensuring that it can adapt to patients with different foot lengths and has a wide range of uses.
