Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, and in particular to a turning support device for the care of critically ill patients. Background Technology

[0002] ICU beds, commonly known as ICU nursing beds (ICU is an abbreviation for Intensive Care Unit), are nursing beds used in intensive care units. Intensive care medicine is a medical organizational management form that integrates modern medical and nursing technologies, which emerged with the development of the medical and nursing profession, the advent of new medical equipment, and the improvement of hospital management systems. ICU beds are an essential piece of medical equipment in ICU wards. They are easy to operate, allowing for multi-directional control of the bed's movement. Control functions are provided on the side rails, footboard, handheld controller, and foot pedals on both sides, allowing nursing staff to easily operate and control the bed according to the most convenient nursing and resuscitation needs. Additionally, they have one-button reset, one-button positioning, and bed exit alarm functions for monitoring the movement of patients during the transitional recovery period. Precise weighing functionality is crucial for critically ill patients in ICU wards who require significant daily fluid exchange. While traditional methods involve manual recording of fluid intake and output, this can easily overlook perspiration or the rapid burning of body fat. Precise weighing allows for continuous weight monitoring, enabling doctors to easily compare data and adjust treatment plans accordingly. This improves data management of changes in patient weight during treatment. Currently, mainstream ICU beds offer weighing accuracy of 10-20g. Back X-ray imaging is also essential for critically ill patients, allowing for imaging within the ICU room. Backrests equipped with X-ray film holder rails allow for near-whole-body X-ray imaging without moving the patient. Flexible movement and braking are also vital for ICU wards, facilitating resuscitation and intra-hospital transport. Centrally controlled brakes and medical omnidirectional wheels are commonly used.

[0003] Existing ICU patient turning and support devices have drawbacks, including being manually operable, which is inconvenient, increases the workload of nurses, and can easily cause injury to the patient's body during manual turning. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems by proposing a turning assistance support device for the care of critically ill patients. It can activate the first motor required according to the direction of turning, and use mechanical transmission to replace medical staff in turning the patient, reducing the workload of medical staff, and making the turning more stable and less likely to cause secondary injury to the patient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A turning support device for intensive care patients includes a base, a bed frame above the base, a mounting groove running vertically through the bed frame, two bed boards rotatably connected within the mounting groove, a height adjustment mechanism between the base and the bed frame, two support plates fixedly connected to the inner wall of the mounting groove, the upper ends of the two support plates abutting the bottoms of the two bed boards respectively, an L-shaped plate fixedly connected to the bottom of the support plate, a first motor mounted on the bottom of the L-shaped plate, an adjusting screw fixedly connected to the output end of the first motor, the upper end of the adjusting screw rotatably connected to the bottom of the support plate, a first slider slidably connected to the L-shaped plate, the adjusting screw passing through the first slider and threadedly connected to it, a second slider slidably connected to the bottom of the bed board and limited in position, a support rod hinged between the first slider and the second slider, four brackets mounted on the bottom of the base, each bracket equipped with locking casters, and two support mechanisms mounted on the base.

[0007] Preferably, a fixedly connected shaft is provided through the bed board, the shaft is rotatably connected to the inner wall of the mounting groove, the shaft is located near the middle of the mounting groove, and the support plate abuts against the bottom of the end of the bed board away from the shaft.

[0008] Preferably, the height adjustment mechanism includes four threaded cylinders rotatably connected to the base. The four threaded cylinders are connected to each other through a transmission mechanism. Each of the four threaded cylinders is threaded with a lifting screw. The upper ends of the four lifting screws are fixedly connected to the bottom of the bed frame. A fixing plate is installed on the base. A second motor is installed on the fixing plate. A short rod is fixedly connected to the output end of the second motor. The short rod passes through the fixing plate and is rotatably connected to it. A first bevel gear is installed on the short rod. A second bevel gear is installed on one of the threaded cylinders. The first bevel gear meshes with the second bevel gear.

[0009] Preferably, the transmission mechanism includes sprockets mounted on four threaded cylinders, and the four sprockets are connected by a chain.

[0010] Preferably, a fixing block is fixedly connected to the bottom of the bed board, a guide rod is fixedly connected to the fixing block, the guide rod passes through the second slider and is slidably disposed therewith, a spring is fixedly connected to the second slider, the other end of the spring is fixedly connected to the fixing block, and the spring is disposed outside the guide rod.

[0011] Preferably, the support mechanism includes a support screw that runs through the base from top to bottom, the support screw being threadedly connected to the base, a support plate being fixed to the bottom of the support screw, and a handwheel being fixed to the upper end of the support screw.

[0012] Preferably, the handwheel is fixedly connected to the support screw by welding, and the outer wall of the handwheel is provided with anti-slip texture.

[0013] Preferably, an anti-slip pad is fixed to the bottom of the support plate, and the anti-slip pad is connected to the support plate by screws. The anti-slip pad is made of rubber.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows:

[0015] 1. Push the bed frame. With the help of the locking casters, the base can be moved, increasing flexibility. After moving it to the appropriate position, manually turn the handwheel to rotate the support screw and drive the support plate down until the anti-slip pad touches the ground. This can limit the support of the base and ensure its stability during use.

[0016] 2. The second motor drives the short rod and the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear and the threaded cylinder to rotate. Under the transmission of the sprocket and chain, the four threaded cylinders can rotate synchronously. In this way, the four lifting screws can move up or down synchronously, thereby adjusting the height of the bed frame to meet different needs.

[0017] 3. Start the first motor. The rotation of the first motor drives the adjustment screw to rotate. Since the first slider cannot rotate under the guidance of the L-shaped plate, the rotation of the adjustment screw can make the first slider move upward. Under the support of the support rod, it drives the second slider sliding rod and compresses the spring, which in turn drives the guide rod and the bed board to rotate, thereby turning the patient's body over. This reduces the workload of medical staff and makes the turning more stable, less likely to cause secondary injury to the patient.

[0018] In summary, this invention can activate the first motor required according to the direction of turning over, and use mechanical transmission to turn the patient over instead of medical staff, reducing the workload of medical staff, and making the turning more stable and less likely to cause secondary injury to the patient.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figure 1-4 A turning support device for intensive care patients includes a base 1, a bed frame 2 above the base 1, an installation groove 21 extending vertically through the bed frame 2, two bed boards 9 rotatably connected within the installation groove 21, a fixed shaft 22 extending through the bed board 9, the shaft 22 rotatably connected to the inner wall of the installation groove 21, the shaft 22 being positioned near the middle of the installation groove 21, and a support plate 8 abutting against the bottom of the bed board 9 at the end away from the shaft 22;

[0026] A height adjustment mechanism is provided between the base 1 and the bed frame 2. The height adjustment mechanism includes four threaded cylinders 3 rotatably connected to the base 1. The four threaded cylinders 3 are connected by a transmission mechanism. The transmission mechanism includes sprockets 4 mounted on the four threaded cylinders 3. The four sprockets 4 are connected by a chain 31.

[0027] Each of the four threaded cylinders 3 is threaded with a lifting screw 5. The upper ends of the four lifting screws 5 are fixedly connected to the bottom of the bed frame 2. A fixing plate 12 is installed on the base 1. A second motor 10 is installed on the fixing plate 12. A short rod 11 is fixedly connected to the output end of the second motor 10. The short rod 11 passes through the fixing plate 12 and is rotatably connected to it. A first bevel gear 13 is installed on the short rod 11. A second bevel gear 14 is installed on the threaded cylinder 3. The first bevel gear 13 and the second bevel gear 14 mesh with each other.

[0028] Two support plates 8 are fixedly connected to the inner wall of the mounting groove 21. The upper ends of the two support plates 8 abut against the bottom of the two bed boards 9 respectively. An L-shaped plate 6 is fixedly connected to the bottom of the support plate 8. A first motor 24 is installed at the bottom of the L-shaped plate 6. An adjusting screw 25 is fixedly connected to the output end of the first motor 24. The upper end of the adjusting screw 25 is rotatably connected to the bottom of the support plate 8. A first slider 23 is slidably connected to the L-shaped plate 6. The adjusting screw 25 passes through the first slider 23 and is threadedly connected to it. A second slider 26 that is limited is slidably connected to the bottom of the bed board 9. A fixing block 30 is fixedly connected to the bottom of the bed board 9. A guide rod 28 is fixedly connected to the fixing block 30. The guide rod 28 passes through the second slider 26 and is slidably set therewith. A spring 29 is fixedly connected to the second slider 26. The other end of the spring 29 is fixedly connected to the fixing block 30. The spring 29 is set outside the guide rod 28.

[0029] A support rod 27 is hinged between the first slider 23 and the second slider 26. One end of the support rod 27 is hinged to the first slider 23, and the other end is hinged to the second slider 26. Four brackets 15 are installed at the bottom of the base 1, and the four brackets 15 are arranged in a rectangular shape. Locking casters 16 are installed on each of the four brackets 15. Two support mechanisms are installed on the base 1. The support mechanism includes a support screw 17 that runs vertically through the base 1. The support screw 17 is threadedly connected to the base 1. A support plate 18 is fixed to the bottom of the support screw 17, and a handwheel 20 is fixed to the upper end of the support screw 17. The handwheel 20 is fixedly connected to the support screw 17 by welding. The outer wall of the handwheel 20 is provided with anti-slip texture. An anti-slip pad 19 is fixed to the bottom of the support plate 18. The anti-slip pad 19 is connected to the support plate 18 by screws. The anti-slip pad 19 is made of rubber.

[0030] When using this invention, medical staff can place the bed frame 2 in a suitable position. The medical staff can push the bed frame 2, and the base 1 can be moved under the action of the locking caster 16, which increases the flexibility. After moving to a suitable position, the handwheel 20 is manually turned to make the support screw 17 rotate and drive the support plate 18 to move down until the anti-slip pad 19 touches the ground. In this way, the base 1 can be supported and limited to ensure its stability during use.

[0031] Then, the height of the bed frame 2 is adjusted according to the needs. The medical staff starts the second motor 10 to drive the short rod 11 and the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 drives the second bevel gear 14 and the threaded cylinder 3 to rotate. Under the transmission of the sprocket 4 and the chain 31, the four threaded cylinders 3 can rotate synchronously. In this way, the four lifting screws 5 can move up or down synchronously, thereby adjusting the height of the bed frame 2 to meet different needs.

[0032] If it is necessary to turn the patient over, the first motor 24 is activated as needed. The rotation of the first motor 24 drives the adjusting screw 25 to rotate. Since the first slider 23 cannot rotate under the guidance of the L-shaped plate 6, the rotation of the adjusting screw 25 can move the first slider 23 upward. Under the support of the support rod 27, the second slider 26 slides and compresses the spring 29, which ultimately drives the guide rod 28 and the bed board 9 to rotate, realizing the turning of the patient's body. This reduces the workload of medical staff and makes the turning more stable, less likely to cause secondary injury to the patient.
