Description

Technical Field

[0001] The present invention relates to the technical field of assisted turning over of patients in a critical care department, and in particular to a device for assisted turning over of patients in a critical care department. Background Art

[0002] The Department of Critical Care Medicine is known as the last line of defense for life. Through systematic medical monitoring and treatment, it provides high-quality life support and nursing services to patients with multiple organ dysfunction or potential high-risk factors. It plays a vital role in the treatment of critically ill patients. Some critically ill patients are unable to move independently, and long-term bed rest can lead to muscle atrophy, decreased strength and joint stiffness. Therefore, nursing staff are needed to assist critically ill patients to turn over and adjust their position to relieve the discomfort caused by long-term pressure.

[0003] For example, the patent with publication number CN211131814U discloses a patient turning device for critical care medicine, including a turning device main body, a split turning mechanism is provided on the upper outer surface of the turning device main body, a control mechanism is provided on one side outer surface of the turning device main body, and a bottom plate is provided on the lower outer surface of the turning device main body; the turning device is provided with a split turning mechanism and a reinforcement mechanism, which can better contact the patient's body through the combined use of soft cushions, and at the same time, the hydraulic press and the telescopic rod are used to achieve uniform turning operation, thereby reducing the impact on critically ill patients, and the safety belt can better ensure that the patient's body will not be significantly displaced, thereby improving the overall protection effect, and the threaded shaft can be rotated by the turntable during use, thereby driving the fastening plate to move horizontally conveniently, thereby better adapting to different models of hospital beds, and bringing better prospects for use.

[0004] For example, the patent with publication number CN221731328U discloses a critical care turning device, including a device body, an adjustment plate and an adjustment mechanism arranged on the outer wall of the adjustment plate, the adjustment mechanism including a sliding assembly; the sliding assembly including a slider and a lifting rod, the outer wall of the device body is rotatably connected to the left turning plate, and the outer wall of the device body is rotatably connected to the right turning plate located on the side of the left turning plate. By setting an auxiliary pull ring, when turning the critically ill patient through the turning device, in order to improve the convenience of adjusting the height of the auxiliary pull ring and improve the effect of the patient's leg rehabilitation training, the servo motor can be turned on to drive the slider to slide along the outer wall of the slide groove through the rotation of the swing rod. The sliding of the slider drives the auxiliary pull ring to perform height adjustment movement through the lifting and lowering of the lifting rod, so as to realize the control operation of improving the effect of the patient's leg rehabilitation training when the critically ill patient lies flat on the bed for recuperation.

[0005] Another example is the patent with publication number CN117064661B which discloses a critical care turning device, comprising a base and an adjustable bed head, wherein the upper surface of the base is provided with a recovery mechanism for facilitating the patient's defecation, the interior of the adjustable bed head is provided with a massage mechanism for helping the patient to relieve back itching, and the interior of the lumbar support is provided with a turning machine for helping critically ill patients to turn over; the driving motor drives the connecting rod to move, compresses the compression spring on the left or right, and the compression spring drives the fixed rod with the same movement direction to move, and the fixed rod drives the limit plate at one end away from the compression spring to move, and the top of the limit plate releases the restriction on the connecting roller in the same direction, and then drives the rack to move under the action of the connecting block and the telescopic roller, and the rack movement causes the half gear meshing with its upper surface to rotate, and the rotation of the half gear drives the turning plate to lift under the action of the connecting roller, that is, drives the critically ill patient to turn over. It reduces the pain of critically ill patients; the width of some existing medical beds is small, and after the patient lies flat on the bed, the distance reserved on both sides to the edge of the bed is short. Generally, in order to ensure the safety of critically ill patients and the convenience of medical examinations, critically ill patients are usually controlled to lie flat in the center of the bed. When the patient is assisted to turn over by a turning device, the patient is close to the edge of the bed after turning over, which increases the risk of falling, and it is inconvenient to adjust the position of the patient's arms and legs on the bed, which may cause compression of the tracheostomy tube port, etc., affecting the patient's treatment. In addition, many critically ill patients cannot move independently, and after turning over, the weight of their body is pressed on the auxiliary turning device, which puts a large lateral pressure on the auxiliary turning device. When the turning device is under pressure for a long time, it is easy to cause local deformation or a smaller auxiliary turning angle, etc., which causes the patient's turning position to change, thereby affecting the patient's treatment.

[0006] In response to the above problems, there is an urgent need to carry out innovative designs based on the existing intensive care unit patient-assisted turning equipment. Summary of the Invention

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-14 The present invention provides the following technical solutions: a patient-assisting turning device for critical care medicine, comprising a bed frame 1 for critically ill patients to lie flat, a middle pad 2 being fitted in the center of the upper surface of the bed frame 1, and side pads 3 being rotatably connected on both sides of the middle pad 2; flexible fabrics 7 are fixedly connected to the sides of the side pads 3, and a driving mechanism for controlling the retraction and extension of the flexible fabric 7 is provided on the bed frame 1, and the driving mechanism can control the movement and steering of the side pads 3 by retracting and extending the flexible fabric 7, thereby assisting critically ill patients to turn over; side grooves 9 are symmetrically opened at the edges of both sides of the bed frame 1, and mounting frames 28 are fixedly installed at the bottom of the bed frame 1 corresponding to the side grooves 9, and a support mechanism for reinforcing the steering state of the side pads 3 is provided on the mounting frame 28.

[0040] The driving mechanism includes a fixing frame 4 fixed on the bed frame 1 for placing medical instruments, and both sides of the fixing frame 4 are rotatably connected to steering brackets 5; a rotating shaft 6 is rotatably installed on the steering bracket 5, and a flexible fabric 7 is wound around the rotating shaft 6.

[0041] A guide rod 8 is fixedly connected to the steering bracket 5 , and the flexible fabric 7 is fitted on the outside of the guide rod 8 . The guide rod 8 is arranged at the side of the rotating shaft 6 .

[0042] The total width of the middle pad 2 and the two side pads 3 is smaller than the width of the bed frame 1, and the thickness of the middle pad 2 is the same as the thickness of the side pads 3; the middle pad 2 and the side pads 3 can fit on the surface of the bed frame 1 and move.

[0043] The critically ill patient lies flat on the middle pad 2 and the side pads 3 on the bed frame 1. When lying flat, the middle pad 2 and the side pads 3 on both sides are controlled to be centrally arranged on the bed frame 1. When it is necessary to assist the critically ill patient to turn over, the motor on the steering bracket 5 controls the rotation of the rotating shaft 6. The rotating shaft 6 can drive the flexible fabric 7 to rotate and reel in or out, and control the flexible fabric 7 on one side to rotate and reel in, and control the flexible fabric 7 on the other side to rotate and reel out. Under the pulling force of the flexible fabrics 7 on both sides, the side pads 3 and the middle pad 2 are controlled to fit and move on the bed frame 1, thereby assisting the critically ill patient to move to one side on the bed frame 1 to prepare for turning over.

[0044] The patient is on one side of the bed frame 1, and there is sufficient space on the other side. The medical staff adjusts the posture of the patient's arms and legs, and then operates the motor on the fixed frame 4 to control the steering bracket 5 to rotate. The steering bracket 5 drives the rotating shaft 6 and the guide rod 8 to rotate synchronously. The rotating shaft 6 controls the lateral pad 3 on one side to rotate upward through the flexible fabric 7. The rotation of the lateral pad 3 can assist the patient to turn over sideways, avoiding critically ill patients from lying flat all the time. After turning over, the patient can lie on the bed frame 1 in a more comfortable posture, avoiding the problem of the patient compressing the tracheostomy tube port due to improper posture.

[0045] Example 2: Based on Example 1, a support mechanism is also disclosed, and its specific structure is as follows: the support mechanism includes an electric slide rail 10 fixed on the mounting frame 28, an electric slide seat 11 is slidably mounted on the electric slide rail 10, and a rectangular frame 12 is fixedly mounted on the electric slide seat 11; a guide slide rail 13 is longitudinally fixedly mounted in the rectangular frame 12, a guide slide bar 14 is slidably connected to the guide slide rail 13, and a U-shaped frame 15 is fixedly mounted on the guide slide bar 14; an upper cylindrical rod 16 is fixedly mounted on the U-shaped frame 15, and a support plate 17 is rotatably sleeved on the upper cylindrical rod 16.

[0046] The support plate 17 is tilted and supported on the side of the lateral pad 3 , and a power mechanism for driving the support plate 17 to move upward and turn is provided in the rectangular frame 12 .

[0047] The power mechanism includes a cylinder 18 fixed in a rectangular frame 12, a movable bracket 19 is fixed to the output end of the cylinder 18, and a lower cylindrical rod 20 is fixedly mounted on the movable bracket 19; a rotating drum 21 is rotatably sleeved on the lower cylindrical rod 20 and the upper cylindrical rod 16, and a transmission push rod 22 is fixedly connected between the two rotating drums 21.

[0048] A transmission rod 23 is rotatably connected to the inner wall of the rectangular frame 12 , and a sliding groove 24 is provided on the outer side of the flexible fabric 7 . One end of the transmission rod 23 is engaged with the sliding groove 24 and is slidably connected.

[0049] A rack 26 is provided inside the rectangular frame 12 and moves along the output direction of the cylinder 18. A gear 27 is meshed and connected next to the rack 26. The gear 27 is rotatably mounted on the inner wall of the rectangular frame 12. The gear 27 is coaxially sleeved on the outside of the transmission rod 23.

[0050] A sliding seat 25 is slidably engaged on the edge of the rectangular frame 12 . The sliding seat 25 is fixedly connected to the rack 26 , and the rectangular frame 12 is fixedly mounted on the movable bracket 19 .

[0051] After rotating the lateral pad 3 to assist the patient in turning over, the rectangular frame 12 is controlled by the electric slide rail 10 and the electric slide seat 11 to move and expand to the outside of the bed frame 1, so that the support plate 17 is completely exposed outside the bed frame 1, and then the cylinder 18 is operated to push the movable bracket 19 to move horizontally, and the movable bracket 19 drives the lower cylindrical rod 20 to move and expand synchronously. At this time, the two ends of the transmission push rod 22 connected between the upper cylindrical rod 16 and the lower cylindrical rod 20 rotate accordingly. The rotating transmission push rod 22 can push the guide slide 14 to engage on the guide slide rail 13 and slide upward. The upward movement of the guide slide 14 drives the U-shaped frame 15 and the support plate 17 to move upward synchronously, adjusting the position of the support plate 17 corresponding to one side of the bed frame 1.

[0052] While the mobile bracket 19 moves laterally, it drives the side sliding seat 25 to engage with the frame of the rectangular frame 12 and slide in a directional manner. The rack 26 on the sliding seat 25 moves laterally synchronously. Under the meshing transmission of the rack 26 and the gear 27, the gear 27 and the transmission rotating rod 23 can be controlled to rotate. When the transmission rotating rod 23 rotates, one side engages in the sliding groove 24 and slides, thereby achieving the purpose of pushing the support plate 17 to rotate and unfold. The support plate 17 rotates and unfolds on one side of the bed frame 1, and then the electric slide rail 10 and the electric slide seat 11 control the lateral movement of the rectangular frame 12 to adjust the lateral position of the support plate 17, so that the support plate 17 is obliquely supported on one side of the lateral pad 3, thereby maintaining the stability of the rotated and unfolded state of the lateral pad 3, so that it can stably maintain the state of the patient turning over, and improve the safety of use.

[0053] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
