Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of turning-over auxiliary devices, in particular to a turning-over auxiliary device for cardiovascular surgery nursing. BACKGROUND

[0002] Turning-over auxiliary devices are a kind of medical tools designed for bedridden patients, aiming to help patients who cannot turn over or have difficulty in turning over (such as critically ill, paralyzed, postoperative rehabilitation, elderly weak, etc.) to change body position, at the same time, to reduce the operation burden of medical staff, and to reduce the risk of complications such as bedsores, pulmonary atelectasis, and muscle atrophy.

[0003] However, cardiovascular surgery often uses a median incision or a lateral thoracic incision, and the incision depth penetrates the skin, subcutaneous fat, chest wall muscle, and pleura. Some surgeries also require opening the pericardium. After surgery, the incision needs to be closed in multiple layers by steel wire (sternum fixation), absorbable suture (muscle, subcutaneous tissue), and skin suture line. In the early postoperative period, the incision is in the acute inflammatory reaction period, and the local tissue is obviously congested and edematous. The healing of the sternum and the surrounding muscles has not formed enough tension, and the change of body position during turning over will directly pull the muscle fibers and subcutaneous nerve endings around the incision, and at the same time, it will cause micro-movement of the sternum fixation site, resulting in severe pain. Even with the assistance of medical staff, the patient will not be able to complete the body position adjustment due to the pain reflexively tightening the limbs, and in order to ensure the safety of the patient after surgery, various drainage tubes and real-time monitoring of vital signs are required. The number of these wires and drainage tubes is large, and the direction is scattered. During turning over, the wires are easy to entangle and knot with the drainage tubes, so that the medical staff needs to comb the direction of the wires and drainage tubes one by one during turning over to avoid entanglement and pulling, which not only prolongs the operation time, but also limits the amplitude and speed of turning over, making it difficult to smoothly complete the turning-over action.

[0032] Embodiment one

[0033] Please refer to Figures 1 to 9The application provides a technical scheme: a turning-over auxiliary device for cardiovascular surgery nursing, which comprises a bed frame 1, further comprises a bed plate 2, the bed plate 2 comprises a fixed part 20 and a lifting part 21, the fixed part 20 is connected with the bed frame 1, an air pump 3 is installed at the bottom of the bed frame 1, the air pump 3 is provided with a plurality of output ends 30, the output ends 30 are provided with control valves 31 outside, a cylinder one 32 is installed outside the lifting part 21, the cylinder one 32 is communicated with one output end 30 of the air pump 3 through a pipeline, a controller 4 is installed on the surface of the bed frame 1, the controller 4 is connected with the control valves 31, the controller 4 is connected with an external medical monitor, through the blood pressure sensor of the medical monitor (such as a multi-parameter monitor), the systolic pressure and diastolic pressure data of a patient are collected in real time, a standard medical signal is output, through a data converter, the medical signal output by the monitor is converted into a signal (such as a digital signal that can be received by PLC) that can be recognized by the controller 4, and the opening and closing of the control valve 31 are adjusted according to the medical signal output by the monitor, a turning-over assembly 5 is connected with the air pump 3, the turning-over assembly 5 is connected with the controller 4, the controller 4 controls the turning-over assembly 5 to work regularly, the turning-over assembly 5 changes the lying posture of the patient after an operation, when the turning-over assembly 5 adjusts the body position of the patient, the controller 4 adjusts the action amplitude of the turning-over assembly 5 according to the vital sign data detected by the medical monitor, a collection assembly 6 is installed on both sides of the bed plate 2, the collection assembly 6 stores the indwelling pipeline and wires on the patient, when the turning-over assembly 5 adjusts the body position of the patient, the collection assembly 6 automatically adjusts the tightness of the wires according to the lateral lying direction of the patient.

[0034] In use, the fixed part 20 of the bed plate 2 is rigidly connected with the bed frame 1, the lifting part 21 keeps horizontal and is flush with the fixed part 20 when there is no air flow input of the cylinder one 32, so that the body of the patient is kept in a horizontal state when the patient lies on his back, the cylinder one 32 is composed of a cylinder barrel, a piston, a piston rod, a spring and a sealing element, compressed air enters the cylinder barrel and drives the piston to move in the axial direction, after the patient's condition is stable, the controller 4 controls the control valve 31 connected with the cylinder one 32 to be opened, so that the piston rod of the cylinder one 32 is elongated, so that the lifting part 21 of the bed plate 2 is lifted, and the bed complications such as pulmonary atelectasis and pressure sores are prevented.

[0035] The turning-over assembly 5 corresponds to the shoulder and back of the patient and the hip respectively, medical staff can set the turning-over instruction regularly through the controller 4, and the turning-over can be completed without manual intervention, so that the workload of medical staff is reduced, when the patient is adjusted from the supine position to the right lateral position, the controller 4 sends a signal to the corresponding control valve 31, so that the corresponding control valve 31 is opened, the turning-over assembly 5 lifts the left half of the patient, and when the left half of the patient is lifted, the length of the indwelling pipeline and wires that are pulled is adjusted through the collection assembly 6, so that the wires do not pull the wound of the patient, and the turning-over assembly 5 also generates a left pulling force on the patient when the left half of the patient is lifted, so that the body of the patient does not slide down, the patient is slowly inclined to the right, and the automatic turning-over action is completed.

[0036] If, during the patient's repositioning process, pressure on the affected limb causes local blood pooling and a temporary reduction in venous return, leading to a drop in blood pressure, the controller 4, connected to an external medical monitor, receives this sudden drop in blood pressure signal. The controller 4 then closes multiple control valves 31, thereby stopping the supply of air pressure to cylinder 32 and the repositioning assembly 5. After the repositioning assembly 5 loses its air supply, the extended side begins to slowly contract, allowing the patient to smoothly return from a tilted position to a supine position, avoiding secondary stimulation to the patient's circulatory system due to sudden changes in body position. At the same time, cylinder 32, without its air supply, begins to contract, causing the lifting part 21 of the bed board 2 to lower and become flush with the fixing part 20, assisting in blood pressure recovery. The repositioning assembly 5 initiates and stops slowly for both repositioning and repositioning, ensuring a gentle and controllable repositioning process and reducing the risk of blood pressure fluctuations.

[0037] The turning component 5 includes a support frame 50, and there are two support frames 50. The two support frames 50 are located at the fixed part 20 and the lifting part 21 of the bed board 2, respectively. The bottom ends of the support frame 50 are fixedly connected to the grippers 51. The outer side of the support frame 50 is rotatably connected to the connecting arm 52. The two connecting arms 52 on the same side are close to each other and have a placement frame 53 at one end. The placement frame 53 is installed on the surface of the bed board 2. The connecting arm 52 is rotatably connected to the placement frame 53. The surface of the support frame 50 is provided with a turning component 54. The two ends of the support frame 50 are respectively provided with a transmission component 55. The transmission component 55 is connected to the output end 30 of the air pump 3.

[0038] When in use, the turning assembly 5 uses grippers 51 to mount the support frame 50 on the fixed part 20 and the lifting part 21 of the bed board 2, so that the two support frames 50 are located under the patient's shoulders and back and buttocks respectively. The placement frame 53 is mounted on the surface of the bed board 2. The support frame 50 and the placement frame 53 are connected by a connecting arm 52, so that when the lifting part 21 of the bed board 2 rises, the support frame 50 mounted on the lifting part 21 can also move synchronously. The multiple output ends 30 of the air pump 3 are connected to four transmission components 55 respectively. When turning is required, if the patient is adjusted to the right lateral position, the controller 4 opens the control valve 31 on the outside of the output end 30 connected to the left transmission component 55, so that the air pump 3 provides air source to the transmission component 55. The transmission component 55 located on the patient's left side provides driving force to the turning assembly 54, so that the turning assembly 54 lifts the patient's left side, and when lifting the patient's left half, it also generates a leftward pulling force on the patient to prevent the patient's body from sliding down, so that the patient can smoothly transition to the right lateral position.

[0039] The transmission component 55 includes a transmission air chamber 56, which is connected to one output end 30 of the air pump 3 via a pipeline. The inner wall of the transmission air chamber 56 has an air vent 57. Sealing plates 58 are slidably connected to both sides of the air vent 57. The sealing plates 58 are slidably connected to the inner wall of the transmission air chamber 56. A spring plate 59 is fixedly connected to the side of the sealing plate 58 away from the air vent 57. The spring plate 59 is used to push the sealing plate 58 back to its initial state when the air pump 3 stops supplying air. A transmission column 510 is fixedly connected to the bottom of the sealing plate 58. The transmission column 510 is slidably connected to the inner wall of the transmission air chamber 56. Adjusting components 511 are provided on the outer sides of the two transmission columns 510 to gradually adjust the flow area of ​​the air vent 57.

[0040] Four transmission air chambers 56 are provided, located at both ends of the two support frames 50, and each transmission air chamber 56 is connected to one output end 30 of the air pump 3. Thus, the controller 4 can precisely supply air pressure to each transmission air chamber 56 by controlling the control valve 31 outside the corresponding output end 30. After the gas supplied by the output end 30 of the air pump 3 enters the transmission air chamber 56, two closely spaced sealing plates 58 block the opening area of ​​the vent 57, making the initial flow area of ​​the vent 57 small, thus reducing the initial flow rate of the gas. During the initial stage, the turning device 54 lifts the patient's side with a small amplitude and slow speed. However, as gas continuously enters the transmission air chamber 56, the gas drives the adjusting device 511 to work. The adjusting device 511 causes the two sealing plates 58 to move away from each other, gradually increasing the flow area of ​​the air vent 57. As a result, the lifting speed of the turning device 54 gradually increases until the rated speed, i.e., when the flow area of ​​the air vent 57 reaches its maximum, the driving force on the turning device 54 changes from small to large, making the amplitude of the turning device 54 when adjusting the patient's position gentle and stable.

[0041] The adjusting component 511 includes an adjusting ring plate 512. Two adjusting grooves 513 are formed on the surface of the adjusting ring plate 512. The two adjusting grooves 513 correspond to two transmission columns 510 respectively. The transmission columns 510 are slidably connected to the inner wall of the adjusting grooves 513. A connecting frame 514 is fixedly connected to the bottom of the adjusting ring plate 512. An axial flow impeller 515 is fixedly connected to the bottom of the connecting frame 514. A fixing frame 516 is fixedly connected to the inner wall of the transmission air chamber 56. The fixing frame 516 is rotatably connected to the axial flow impeller 515.

[0042] When the air pump 3 supplies air to the transmission air chamber 56, the air enters and first impacts the axial flow impeller 515. The axial flow impeller 515 rotates under the push of the airflow and drives the connecting frame 514 to rotate. The connecting frame 514 drives the adjusting ring plate 512 to rotate. When the adjusting ring plate 512 rotates, it drives the adjusting groove 513 to rotate, causing the inner wall of the adjusting groove 513 to squeeze the transmission column 510. After being squeezed, the transmission column 510 moves linearly on the inner wall of the transmission air chamber 56. The transmission column 510 is fixed to the sealing plate 58, so that the two transmission columns 510 drive the two sealing plates 58 to move away from each other, thereby increasing the airflow area of ​​the vent 57. This increases the flow rate of air from the inner wall of the transmission air chamber 56 into the turning component 54, so that when turning the patient, the movement amplitude gradually transitions to the predetermined speed, avoiding large adjustment amplitudes that may cause fluctuations in the patient's blood pressure.

[0043] When the patient's blood pressure drops suddenly, the controller 4 closes multiple control valves 31, and the air pump 3 stops supplying air to the transmission air chamber 56. As a result, the spring plate 59 pushes the sealing plate 58 to reset. When the sealing plate 58 resets, it drives the transmission column 510 to move. When the transmission column 510 slides on the inner wall of the transmission groove, it pushes the adjusting ring plate 512 to rotate and reset. At this time, the compressed gas in the cylinder 2 518 can only be discharged through the minimum flow area of ​​the vent 57, so that the silicone plate 517 slowly returns to the horizontal state, avoiding secondary stimulation to the patient's body caused by the fast adjustment speed.

[0044] The turning device 54 includes a silicone plate 517, with two silicone plates 517 corresponding to the patient's shoulder, back, and buttocks respectively. Each end of the silicone plate 517 is equipped with a second cylinder 518. The output end 30 of the second cylinder 518 is fixed to the silicone plate 517. The cylinder barrel of the second cylinder 518 is fixed to the support frame 50. The second cylinder 518 is connected to the transmission air chamber 56. Each end of the silicone plate 517 is fixedly connected to a fixing box 519. A winding drum 520 is rotatably connected to the inner wall of the fixing box 519. A turning belt 521 is wound between the two winding drums 521. A winding component 522 is provided on the outside of the winding drum 522, which drives the winding drum 520 to wind up the turning belt 521 when the second cylinder 518 on the same side extends.

[0045] Two silicone pads 517 are located below the patient's shoulder and back and buttocks, respectively, making flexible contact with these areas. When the patient is adjusted from a supine position to a right lateral position, the controller 4 opens the control valve 31, which is connected to the transmission air chamber 56 under the patient's left side. This allows the air pump 3 to supply air to the transmission air chamber 56 under the patient's left side through its output end 30. The air then enters the cylinder 518 through the transmission air chamber 56. The cylinder 518 consists of a cylinder barrel, piston, piston rod, spring, and seals. Compressed air entering the cylinder pushes the piston axially, thereby dislodging the silicone pads under the patient's body. The left side of the silicone pad 517 is lifted. Since the left sides of both silicone pads 517 are lifted by cylinder 518, the patient's back and left buttocks are raised, and the patient begins to tilt to the right. At the same time, the winding component 522 on the left side drives the winding drum 520 on the left side to rotate. The winding drum 520 winds up the turning belt 521, so that the turning belt 521 generates a leftward pulling force under the patient, helping the patient maintain the side-lying position and preventing the body from sliding down. After cylinder 518 moves to its maximum stroke, the action of adjusting from the supine position to the right side-lying position is completed, and the patient completes the turning.

[0046] The take-up component 522 includes a transmission box 523. A transmission shaft 524 is rotatably connected to the inner wall of the transmission box 523. The transmission shaft 524 is coaxially arranged with the take-up drum 520 and is fixedly connected to the take-up drum 520. A transmission gear 1 525 is fixedly connected to the outer side of the transmission shaft 524. A transmission gear 2 526 meshes with the outer side of the transmission gear 1 525. One end of the transmission gear 2 526 is rotatably connected to the inner wall of the transmission box 523. The other end of the transmission gear 2 526 is fixedly connected to a cross-flow impeller 527. The cross-flow impeller 527 is rotatably connected to the inner wall of the transmission box 523. An air supply pipe 528 is connected to the inner wall of the transmission box 523. The end of the air supply pipe 528 away from the transmission box 523 is connected to the transmission air chamber 56.

[0047] When the airflow output from the air pump 3 enters the transmission air chamber 56 under the left side of the patient, the transmission air chamber 56 on the left side supplies air to the transmission box 523 through the air supply pipe 528. When the air supply pipe 528 sprays air into the transmission box 523, the sprayed gas impacts the blades of the cross-flow impeller 527, causing the cross-flow impeller 527 to rotate. The cross-flow impeller 527 drives the transmission gear 2 526 to rotate, the transmission gear 2 526 drives the transmission gear 1 525 to rotate, the transmission gear 1 525 drives the transmission shaft 524 to rotate, and the transmission shaft 524 drives the take-up drum 520 to rotate, thereby causing the take-up drum 520 under the left side of the patient to take up the turning belt 521, so that the turning belt 521 generates a leftward pulling force on the patient's body.

[0048] The gathering assembly 6 includes a fixed gathering plate 60 and a movable gathering plate 61. The fixed gathering plate 60 is fixed to the placement frame 53, and the movable gathering plate 61 is slidably connected to the surface of the placement frame 53. Hooks 62 are respectively installed at both ends of the silicone plate 517 located in the fixed part 20. A pull rope 63 is fixedly connected to the surface of the movable gathering plate 61. The end of the pull rope 63 away from the movable gathering plate 61 passes through the inner wall of the placement frame 53 and can be connected to the hook 62 on the same side. The movable gathering plate 61 and the placement frame 53 are slidably connected to the silicone plate 517 located in the fixed part 20. A compression spring 64 is fixedly connected between the racks 53. A take-up ring 65 is provided between the fixed take-up plate 60 and the movable take-up plate 61. The take-up ring 65 is a non-closed circular ring. A telescopic rod 66 is provided on the outside of the take-up ring 65. The telescopic rod 66 is composed of an unfolding rod, a fixed cylinder and a spring. The spring has a small elastic coefficient and can easily extend and retract when the movable take-up plate 61 moves. The output end 30 of the telescopic rod 66 is fixed to the take-up ring 65, and the mounting end of the telescopic rod 66 is fixed to the rack 53.

[0049] In use, medical staff fix the indwelling tubing and the lines monitoring vital signs on the patient in the storage slot of the fixed cable tray 60, and then pass them through the cable loop 65. Since the cable loop 65 is not a closed loop, it is convenient for medical staff to put the lines in. Finally, the lines that have passed through the cable loop 65 are put into the movable cable tray 61.

[0050] When the patient changes from a supine position to a right lateral position, the patient's left side will tilt upwards. To avoid pulling on the wiring on the patient's left side, the left side of the silicone plate 517 will be lifted by the cylinder 518. As the left side of the silicone plate 517 rises, the hook 62 will pull the pull rope 63 attached to it. The pull rope 63 tightens and pulls the movable spool plate 61, causing the movable spool plate 61 to move closer to the patient, thus preventing the patient from pulling on the cables when tilting to the left. When the movable spool plate 61 moves, it increases the distance between the movable spool plate 61 and the fixed spool plate 60. The cable between the movable spool plate 61 and the fixed spool plate 60 pushes the take-up ring 65 to move. The take-up ring 65 pushes the telescopic rod 66 to retract, preventing the patient from pulling on the wiring when turning over.

[0051] Example 2

[0052] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the fixed part 20 of the bed board 2 is provided with a support plate 7 on both sides. One end of the support plate 7 is fixedly connected to a rotating shaft 8, which is rotatably connected to the inner wall of the bed board 2. One end of the rotating shaft 8 passes through the bed board 2 and is fixedly connected to a transmission gear 3 9. A transmission gear 4 10 meshes with the outer side of the transmission gear 3 9. One end of the transmission gear 4 10 is rotatably connected to the bed board 2, and the other end of the transmission gear 4 10 is fixedly connected to a synchronous pulley 11. The synchronous pulley 11 is rotatably connected to the inner wall of the bed board 2, and a synchronous rope 12 is wound around the outer side of the synchronous pulley 11. The synchronous rope 12 is connected to a hook 62 located on the other side of the bed board 2, that is, the two synchronous ropes 12 are staggered.

[0053] Initially, the support plates 7 on both sides of the bed board 2 are horizontal, and the rotating shaft 8 is not triggered to avoid interfering with the patient's initial position. When the patient changes from a supine position to a right lateral position, the silicone plate 517 under the patient's left side rises. The silicone plate 517 drives the hook 62 to rise, and the hook 62 pulls the synchronous rope 12 attached to it, thereby causing the synchronous wheel 11 under the patient's right side to rotate. The synchronous wheel 11 drives the transmission gear 4 10 to rotate, the transmission gear 4 10 drives the transmission gear 3 9 to rotate, and the transmission gear 3 9 drives the rotating shaft 8 to rotate. This rotation causes the support plate 7 to rotate, and the support plate 7 slowly rises from a horizontal position to fit the patient's right waist and buttocks, providing support for the lateral position and preventing the patient from shifting position due to muscle weakness.
