Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of patient rehabilitation training, and in particular to a rehabilitation training auxiliary device for critically ill patients and a working method thereof. Background Art
[0002] ICU-acquired weakness (ICU-AW) is a common acquired neuromuscular dysfunction in critically ill patients and one of the more serious complications of ICU stay. ICU-AW not only prolongs the patient's ICU mechanical ventilation time and hospital stay, increasing medical costs, but also seriously affects the patient's long-term quality of life. ICU-AW is characterized by symmetrical limb weakness, with proximal limb muscles (such as shoulders and hips) more significantly affected than distal ones, while facial and extraocular muscles are less affected. It can also affect the ventilator and often occurs in mechanically ventilated patients. Clinical manifestations include difficulty weaning from the ventilator, mild paresis or quadriplegia, decreased reflexes, and muscle atrophy.
[0003] Currently, ICU-AW patients need to undergo leg rehabilitation training, but their legs are weak and they often become exhausted after a short training period, resulting in poor training results and affecting the patient's recovery. To this end, we propose a rehabilitation training auxiliary device for critically ill patients and its working method. Summary of the Invention

[0007] An arc-shaped plate, a connecting rod is fixed to the bottom of the arc-shaped plate, the connecting rod passes through the top of the bed and is slidably connected to the bed, a spring is fixed to the inner wall of the bed, the end of the spring away from the bed is fixed to the connecting rod, the bottom of the connecting rod is hinged with a support rod, the end of the support rod away from the connecting rod is hinged to the top of the sleeve rod, the sleeve rod is penetrated by the fixed rod and is slidably connected to the fixed rod, the right side of the fixed rod is fixed to the inner wall of the bed, and a rubber plate is fixed to the left side of the sleeve rod.
[0008] Preferably, a conductive copper sheet is fixed to the left side of the rubber plate, a motor is fixed to the inner wall of the bed, a half gear is fixed to the output shaft of the motor, a tooth plate is slidably installed on the inner wall of the bed, the motor is electrically connected to the power supply through wires A and wires B, the power supply is fixed to the inner wall of the bed, a break is provided on wire B, and wires A and wires B are fixed to the inner wall of the bed through straps. When the patient lies on the bed with his legs placed on the leg support, the arc plate moves downward with the connecting rod under the action of gravity, and the connecting rod pushes the sleeve rod to move to the left through the support rod, and the sleeve rod drives the rubber plate and the conductive copper sheet to move to the left, and the conductive copper sheet contacts the break of wire B, so that the circuit between the motor and the power supply is closed, so that the motor starts working, and the half gear can engage with the teeth on the tooth plate, so that the tooth plate moves back and forth.
[0009] Preferably, a groove is provided on the left side of the tooth plate, and teeth are provided on the upper and lower sides of the groove on the left side of the tooth plate. During the rotation process, the half gear intermittently engages with the teeth on the upper and lower sides of the tooth plate groove, so that the tooth plate can move back and forth.
[0010] Preferably, a through hole is opened on the right side of the bed body, the main support passes through the through hole on the right side of the bed body and is hinged to the bed body, the right side of the main support is hinged with a sub-support, the surface of the sub-support is fixed with a rotating shaft, the rotating shaft passes through the main support and is rotatably connected to the main support, the surface of the rotating shaft is fixed with a spiral spring, the end of the spiral spring away from the rotating shaft is fixed to the main support, and the sub-support can swing up and down at the position hinged to the main support.
[0011] Preferably, the swinging part includes an L-shaped top block, which is fixed to the right side of the bed body, a trapezoidal block is fixed to the surface of the auxiliary support, a circular ring is fixed to the surface of the main support, a rubber ball is fixed to the inner side of the circular ring, and a protrusion is fixed to the surface of the rotating shaft. When the main support swings the auxiliary support back and forth, the L-shaped top block abuts against the trapezoidal block, and cooperates with the spiral spring to allow the auxiliary support to swing up and down. When the auxiliary support drives the rotating shaft to rotate, the rotating shaft drives the protrusion to abut against the rubber ball, so that the speed of the auxiliary support swinging up and down is slowed down, thereby improving the comfort of the patient.
[0012] Preferably, the tops of the main support and the auxiliary support are provided with U-shaped grooves for the patient's legs to be placed in, thereby improving the patient's comfort.
[0013] Preferably, a groove is provided on the right side of the tooth plate, and a horizontal plate is fixed on the left side of the main support, and the horizontal plate is inserted into the groove on the right side of the tooth plate. When the tooth plate moves back and forth, the tooth plate can push the horizontal plate to make the main support swing back and forth at the position hinged to the bed body.
[0014] The present invention also provides a working method of a rehabilitation training auxiliary device for critically ill patients, the working method of the rehabilitation training auxiliary device for critically ill patients comprising the following steps:
[0015] Step 1: The patient lies on the bed with his legs placed on the leg support. Under the action of the gravity of the patient's legs, the auxiliary support swings downward at a certain angle at the hinged position with the main support. At this time, the trapezoidal block fixed on the surface of the auxiliary support is at the same level as the L-shaped top block.
[0016] Step 2: Under the action of the patient's gravity, the curved plate is pressed downward, and the curved plate moves downward together with the connecting rod. The connecting rod pushes the sleeve rod to the left through the support rod. The sleeve rod moves the rubber plate and the conductive copper sheet to the left. At this time, the conductive copper sheet contacts the broken part of the wire B, so that the circuit between the motor and the power supply is closed, and the motor starts to work. The motor drives the half gear to rotate, and the half gear drives the toothed plate to move back and forth. The toothed plate contacts the cross plate, so that the main support swings back and forth at the hinged position with the bed body, so that the patient's thigh performs swinging exercise, assisting the patient in rehabilitation training;
[0017] Step 3: As the main support drives the secondary support to swing back and forth, the trapezoidal block on the secondary support surface contacts the L-shaped top block, cooperating with the volute spring to cause the secondary support to swing up and down with the hinged position with the main support as the center. As the secondary support drives the rotating shaft to rotate, the rotating shaft drives the protrusion to rotate. The protrusion contacts the rubber ball, slowing down the secondary support's up and down swinging speed, assisting the patient in calf swinging training.
[0018] Step 4: After the rehabilitation training, the patient stands up from the bed, and the arc plate is no longer pressed. Under the action of spring 1, the connecting rod moves the arc plate upward and resets. The connecting rod pulls the sleeve rod to the right through the support rod. The sleeve rod resets the rubber plate and the conductive copper sheet to the right, disconnecting the circuit between the motor and the power supply, and the motor stops working.
[0019] Compared with the prior art, the present invention provides a rehabilitation training auxiliary device for critically ill patients and a working method thereof, which has the following beneficial effects:
[0020] 1. The rehabilitation training auxiliary device for critically ill patients and its working method, through the provided leg support part, swing part and driven part, the patient lies on the bed and places his legs on the leg support part, and the leg support part can support the patient's legs to perform forward and backward and up and down swing training, assisting the patient in leg muscle exercise and avoiding the patient from feeling weak after not exercising.
[0021] 2. This rehabilitation training auxiliary device for critically ill patients and its working method: when the main support leads the auxiliary support to swing back and forth, the L-shaped top block abuts against the trapezoidal block, and cooperates with the scroll spring to allow the auxiliary support to swing up and down. When the auxiliary support drives the rotating shaft to rotate, the rotating shaft drives the protrusion to abut against the rubber ball, which slows down the speed of the auxiliary support's up and down swinging, thereby improving the patient's comfort.
[0022] 3. This rehabilitation training auxiliary device for critically ill patients and its working method: when in use, the patient lies on the bed and presses the arc-shaped plate, and the leg support part will swing. After the patient completes the training, he gets off the bed, and the leg support part will stop swinging. There is no need for the patient to operate manually, and it is easy to use.

When the patient lies on the bed 1 with his legs placed on the leg support 2, the arc plate 31 is acted upon by gravity to move the connecting rod 32 downward. The connecting rod 32 pushes the sleeve rod 35 to move to the left through the support rod 34. The sleeve rod 35 drives the rubber plate 37 and the conductive copper sheet 38 to move to the left. The conductive copper sheet 38 contacts the break of the wire B314, closing the circuit between the motor 39 and the power supply 313.

[0037] Example 2
[0038] In this embodiment, a working method of a rehabilitation training auxiliary device for critically ill patients is provided. The working method of the rehabilitation training auxiliary device for critically ill patients includes the following steps:
[0039] Step 1: The patient lies on the bed 1 with his legs placed on the leg support 2. The auxiliary support 22 is affected by the gravity of the patient's legs, and the auxiliary support 22 swings downward at a certain angle at the position where it is hinged to the main support 21. At this time, the trapezoidal block 42 fixed on the surface of the auxiliary support 22 is on the same horizontal line as the L-shaped top block 41.
[0040] Step 2: Under the action of the patient's gravity, the curved plate 31 is pressed downward, and the curved plate 31 moves downward together with the connecting rod 32. The connecting rod 32 pushes the sleeve rod 35 to move to the left through the support rod 34. The sleeve rod 35 moves to the left with the rubber plate 37 and the conductive copper sheet 38. At this time, the conductive copper sheet 38 contacts the break of the wire B314, so that the circuit between the motor 39 and the power supply 313 is closed, and the motor 39 starts to work. The motor 39 drives the half gear 310 to rotate, and the half gear 310 drives the tooth plate 311 to move back and forth. The tooth plate 311 contacts the cross plate 5, so that the main support 21 swings back and forth at the hinged position with the bed body 1, so that the patient's thigh performs swinging exercise, assisting the patient in rehabilitation training;
[0041] Step 3: As the main support 21 drives the auxiliary support 22 to swing back and forth, the trapezoidal block 42 on the surface of the auxiliary support 22 contacts the L-shaped top block 41, cooperating with the volute spring 7, causing the auxiliary support 22 to swing up and down with the hinged position with the main support 21 as the center. As the auxiliary support 22 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the protrusion 45 to rotate, and the protrusion 45 contacts the rubber ball 44, slowing down the speed of the auxiliary support 22's up and down swinging, thereby assisting the patient in performing calf swing training.
[0042] Step 4: After the rehabilitation training is completed, the patient stands up from the bed 1, and the curved plate 31 is no longer pressed. Under the action of spring 1 33, the connecting rod 32 moves the curved plate 31 upward and resets. The connecting rod 32 pulls the sleeve rod 35 to the right through the support rod 34. The sleeve rod 35 resets the rubber plate 37 and the conductive copper sheet 38 to the right, so that the circuit between the motor 39 and the power supply 313 is disconnected, and the motor 39 stops working.
[0043] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
