Description

Technical Field

[0001] The 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 so that some unconventional treatments can be performed 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 movements are 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 a control method for early postoperative rehabilitation of patients with craniocerebral trauma, which can guide 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 body, and a surrounding mechanism and a flexion and extension mechanism arranged on both sides of the bed body;

[0006] The surrounding mechanism includes a bracket, a telescopic rod, a power source and a rotating rod. The bracket is detachably connected to the end 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, and the rotating rod is perpendicular to the rotating shaft of the power source. A clamping part is installed at one end of the rotating rod away from the power source, and the toe part of the patient is 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 rotatably hinged with the tail of the bed, the rotating plate is connected to a first rotating mechanism for controlling its rotation, a baffle is provided on the peripheral side of one end of the rotating plate away from the first rotating mechanism, the cylinder is arranged on the side of the rotating plate, 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 directly opposite to it, a card block is provided on the outer surface of the airbag, a plurality of card slots arranged in sequence are provided on the rotating plate and the baffle connected to the airbag correspondingly, gas is built in the cylinder, 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 body, which is convenient for patients to exercise while lying in bed. The bracket surrounding the mechanism is detachably connected to the bed body, which is convenient for disassembly and assembly to adjust the position.

[0009] The two ends of the telescopic rod are connected to the bracket and the power source respectively. The power source controls the rotating rod to rotate in a circle. The patient's toes are clamped with the clamping part on the rotating rod. The rotating shaft rotates to drive the patient's foot to rotate in a circle, guiding the patient's ankle joint to automatically move 360° around. The telescopic rod can be extended and retracted to adjust the length, control the distance between the flexible rotating rod and the patient's foot, and adapt to different sizes of foot lengths.

[0010] The rotating plate is arranged at the end of the bed and is controlled to rotate by the first rotating mechanism. When in use, the sole of the patient's foot fits against the rotating plate, and the rotating plate rotates, driving the patient's foot to perform toe flexion and dorsiflexion. A baffle is arranged around the rotating plate in contact with the patient's toes, and the patient's foot extends into the space enclosed by the baffle, and the baffle is used to initially limit the patient's position.

[0011] The airbag is arranged on the side of the rotating plate that contacts the patient's foot and on the baffle plate facing it, and cooperates with the movement of the piston in the cylinder to realize the filling and exhaust of the airbag in sequence. The piston in the cylinder is provided with a magnetic ring, and the rotating plate is provided with a permanent magnet. There is a magnetic attraction between the two. When the rotating plate rotates to move the permanent magnet, the magnetic ring can move straight up or down in 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 and lifts up 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 toe position of the patient's foot, ensuring that the toe is fully straightened during the patient's 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, sucking the gas in the airbag on the rotating plate into the cylinder, and the airbag on the rotating plate shrinks without affecting the patient's toe flexion movement. Similarly, when the rotating plate turns upward, the airbag on the baffle also shrinks.

[0015] The airbag is provided with a clamping block which can be clamped with clamping slots at different positions on the correspondingly 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 be used by 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 first bed board and the second bed board to rotate independently;

[0018] The first bed board and the second bed board are provided with a plurality of grooves, the massage ejector is placed in the grooves, and the massage ejector is connected with a telescopic mechanism for controlling the telescopic movement thereof.

[0019] Two bed boards are provided. When one side needs to be turned 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] At the same time, grooves and ejectors are set on the bed board. The telescopic mechanism controls the ejectors to intermittently eject and massage the patient's back. If one side of the ejectors is ejected, the patient's back can be turned over 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 length of the connecting rod can be adjusted through the structure of rod one and rod two, which can change the size of the patient's toe circle, and conduct multi-size circle training, with better training effect. The clamping part is directly sleeved on the rod two, and when the rod two and the rod one are threaded and rotated, the position of the clamping part can be manually adjusted, which is flexible to use.

[0023] Furthermore, the encircling 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 with the connecting hole.

[0026] The rotating shaft is threadedly connected to connecting holes at different heights on the bracket, and the height position of the telescopic rod is adjusted to adapt to patients with different foot lengths, and the disassembly and assembly are convenient.

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

[0028] A positioning recess is provided, and when the patient performs ankle pump exercise, the patient's heel is placed in the positioning recess for easy positioning. The elastic protective layer contacts the patient to increase 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 sole of 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 sole of the patient's foot;

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

[0034] The pressure sensor at the bottom of the rotating board detects the plantar flexion pressure P1 during plantar flexion, and the pressure sensor at the bottom of the rotating board detects the dorsiflexion pressure P2 during dorsiflexion, 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, and the rotation amplitude of the rotating board when the test movement reaches the pressure threshold is determined;

[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 movement needs, thereby achieving better rehabilitation training effects. BRIEF DESCRIPTION OF THE DRAWINGS

The bracket 1 is detachably connected to the bed end side of the bed body 8, such as by setting a snap connection, or setting threaded holes at different positions for screw connection. One end of the telescopic rod 2 (the existing adjustable telescopic rod 2 structure can be used) is connected to the bracket 1, and the other end of the telescopic rod 2 is connected to the power source 3 (such as bonding, welding, riveting, etc.), and the power source 3 adopts a motor. The rotating shaft of the power source 3 is connected to one end of the rotating rod 4 (such as welding, bonding, pin connection, etc.), and 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 installed with a clamping part 10 (such as a clamping groove made of rubber, sponge, etc., or an elastic bandage, etc.), and the patient's toe part is clamped with the clamping part 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 rotatably hinged with the tail of the bed body 8. The rotating plate 5 is connected to a first rotating mechanism for controlling its rotation. A baffle 9 is provided on the peripheral side of one end 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, a magnetic ring is arranged on the piston in the cylinder 6, a permanent magnet attracted to the magnetic ring is arranged on the side of the rotating plate 5 away from the first rotating mechanism, and the airbags 7 are arranged on the side of the rotating plate 5 in contact with the patient's foot and on the baffle 9 directly opposite to it, a card block is arranged on the outer surface of the airbag 7, and a plurality of card slots arranged in sequence are arranged on the rotating plate 5 and the baffle 9 corresponding to the airbag 7, gas is contained in the cylinder 6, 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] When in use, the power source 3 is started, and the power source 3 controls the rotating rod 4 to rotate in a circle, the patient's toes are engaged with the clamping part 10 on the rotating rod 4, and the rotating shaft rotates to drive the patient's foot to rotate in a circle, guiding the patient's ankle joint to automatically move 360 ​​degrees around. The telescopic rod 2 is telescopic to adjust the length, control the distance between the flexible rotating rod 4 and the patient's foot, and adapt to different sizes of foot lengths.

[0047] The rotating plate 5 is arranged at the end of the bed and is controlled to rotate by the first rotating mechanism. When in use, the sole of the patient's foot is in contact with the rotating plate 5, and the rotating plate 5 rotates to drive the patient's foot to perform toe flexion and dorsiflexion. A baffle 9 is arranged around the rotating plate 5 that contacts the patient's toes, and the patient's foot extends into the space surrounded by the baffle 9, and the baffle 9 is used to initially limit the patient's position.

[0048] The airbag 7 is arranged on the side of the rotating plate 5 that contacts the patient's foot and on the baffle plate 9 that faces it, and cooperates with the movement of the piston in the cylinder 6 to realize the sequential filling and exhaust of the airbag 7. The piston in the cylinder 6 is provided with a magnetic ring, and the rotating plate 5 is provided with a permanent magnet. There is a magnetic attraction between the two. When the rotating plate 5 rotates to move the permanent magnet, the magnetic ring can move straight up or down in the cylinder 6 accordingly.

[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 due to the magnetic attraction of the permanent magnet, and pushes the gas above the piston in the cylinder 6 into the airbag 7 on the rotating plate 5. The airbag 7 gradually expands and lifts up 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 toe position of the patient's foot, ensuring that the toe is fully straightened during the patient's 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, sucking the gas in the airbag 7 on the rotating plate 5 into the cylinder 6, and the airbag 7 on the rotating plate 5 shrinks, which does not affect 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 correspondingly connected rotating plate 5 and the baffle 9, so as to adjust 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.
