Description
Technical Field
[0001] This utility model relates to the field of easy bed transfer technology; more specifically, it relates to a micro-turning decompression easy bed transfer method. Background Technology
[0002] A bed-turning aid is a nursing assistive device designed for bedridden patients. It is typically used to help them move or change positions more easily in bed, reducing the workload of caregivers while improving patient comfort and safety. It helps patients turn over, sit up, or move to other positions in bed and is a special device used in hospital, nursing home, or home care environments.
[0003] Currently, existing bed-transfer devices have several drawbacks. Due to their relatively simple structure, patients may fall off during transfers due to staff negligence or patients turning over on their own, reducing the device's safety. Furthermore, most existing devices lack movable structures, which could cause pressure injuries to patients who are bedridden for extended periods and unable to change position independently, further diminishing the device's practicality. Therefore, a micro-turning decompression bed-transfer device is urgently needed to address these issues. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a micro-turning decompression bed transfer method to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a micro-turning decompression bed transfer method, comprising:
[0006] The mounting plate has support legs fixedly connected to the four corners at the bottom end of the mounting plate, and universal wheels are fixedly connected to the bottom surface of the support legs. The outer surfaces at both ends of the bottom end of the mounting plate are provided with protective structures. The mounting plate has an adjustment structure inside, and a first shim is provided at the middle position of the upper end of the adjustment structure. Second shims are provided on both sides of the upper end of the adjustment structure.
[0007] The protective structure includes a fixing frame, and there are four sets of fixing frames, and all four sets of fixing frames are fixedly connected to the bottom surface of the mounting plate.
[0008] The adjustment structure includes threaded holes, and there are two sets of threaded holes, with the two sets of threaded holes respectively opened inside the two sides of the mounting plate.
[0009] Preferably, the protective structure further includes a movable groove, and there are eight sets of movable grooves. The eight sets of movable grooves are respectively opened inside the two ends of the four sets of fixed frames. A movable plate and a protective plate are inserted into the movable groove, and the movable plate and the protective plate are hinged together. This design allows the movable plate and the protective plate to move inside the movable groove.
[0010] Preferably, the movable groove does not penetrate the interior of the fixed frame. The movable groove is a rectangular groove, and the outer surfaces of both ends of the movable plate are provided with limiting blocks. The internal dimensions of the rectangular groove are adapted to the external dimensions of the limiting blocks. A rectangular opening is provided at one end of the movable groove, and rectangular movable blocks are provided on the outer surfaces of both ends of the protective plate. The external dimensions of the rectangular movable blocks are adapted to the internal dimensions of the rectangular opening. This design ensures that the movable plate will not detach from the interior of the movable groove when it moves inside the movable groove.
[0011] Preferably, a torsion spring is provided inside the hinged connection between the movable plate and the protective plate. This design allows the protective plate to rotate upwards by the elasticity of the torsion spring after it moves out of the movable slot.
[0012] Preferably, the adjustment structure further includes a bolt, and the bolt is threaded into the inside of the threaded hole. A support plate is attached to the middle position of the upper end of the mounting plate, and hinge plates are attached to the outer surfaces of both sides of the upper end of the mounting plate. The outer surfaces of both sides of the support plate are respectively hinged to the two sets of hinge plates. The first washer is fixedly connected to the upper surface of the support plate, and the two sets of second washer are respectively fixedly connected to the upper surfaces of the two sets of hinge plates. This design allows the bolt to move up and down inside the threaded hole.
[0013] Preferably, the outer surface of the upper end of the bolt abuts against the outer surface of the lower end of the hinge plate. This design allows the bolt to drive the hinge plate to rotate upwards in a hinged manner.
[0014] The technical effects and advantages of this utility model are as follows: This utility model moves the protective plate outward from inside the moving groove. When the protective plate is detached from the inside of the moving groove, the torsion spring inside the moving plate and the protective plate causes the protective plate to automatically hinge and rotate upward. Thus, through four sets of protective plates perpendicular to the outer surface of the upper end of the mounting plate, the patient on the upper outer surface of the first and second pads can be protected, which can prevent the patient from falling off the equipment during use and improve the safety of the equipment to a certain extent.
[0015] By rotating the bolt, the bolt moves upward inside the threaded hole, causing the bolt to drive the hinge plate to rotate upward and hinge. At the same time, the ends of the two sets of second pads that are far apart from each other rotate upward and hinge. This allows the patient lying on the first and second pads to turn slightly, so that the skin of the patient at the pressure point is slightly removed from the device, reducing local pressure and promoting blood circulation at the pressure point. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example 1
[0024] like Figures 1-3 As shown, this embodiment proposes a micro-turning decompression bed transfer method, including:
[0025] Mounting plate 1, with support legs 2 fixedly connected to the four corners of the lower end of mounting plate 1, and casters 3 fixedly connected to the bottom surface of the support legs 2. Protective structure 4 is provided on the outer surface of both ends of the lower end of mounting plate 1. Protective structure 4 includes a fixing frame 41, and there are four sets of fixing frames 41. All four sets of fixing frames 41 are fixedly connected to the bottom surface of mounting plate 1. Protective structure 4 also includes a moving groove 42, and there are eight sets of moving grooves 42. The eight sets of moving grooves 42 are respectively opened inside the two ends of the four sets of fixing frames 41. Moving plate 43 and protective plate 44 are inserted into the moving groove 42, and the moving plate 43 and protective plate 44 are hingedly connected.
[0026] The movable groove 42 does not penetrate the interior of the fixed frame 41. The movable groove 42 is a rectangular groove. The outer surfaces of both ends of the movable plate 43 are provided with limiting blocks, and the internal dimensions of the rectangular groove are adapted to the external dimensions of the limiting blocks. A rectangular opening is provided at one end of the movable groove 42. The outer surfaces of both ends of the protective plate 44 are provided with rectangular movable blocks, and the external dimensions of the rectangular movable blocks are adapted to the internal dimensions of the rectangular openings. A torsion spring is provided inside the hinged connection between the movable plate 43 and the protective plate 44.
[0027] In this embodiment, the movable plate 43 and the protective plate 44 can move inside the movable groove 42, and the movable plate 43 will not move out of the movable groove 42. When the protective plate 44 moves inside the movable groove 42, one end of the outer side of the protective plate 44 will not penetrate into the movable groove 42. When the protective plate 44 moves outward and leaves the movable groove 42, the torsion spring between the movable plate 43 and the protective plate 44 causes the protective plate 44 to automatically hinge and rotate upward and become perpendicular to the upper outer surface of the mounting plate 1. Thus, the four sets of protective plates 44 can protect the patient at the upper end of the first pad 6 and the second pad 7 and remind the patient of the edge position of the device, which can prevent the patient from falling during the movement of the device.
[0028] Example 2
[0029] like Figure 4 and Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:
[0030] An adjustment structure 5 is provided inside the mounting plate 1. A first shim 6 is provided at the middle position of the upper end of the adjustment structure 5, and second shims 7 are provided on both sides of the upper end of the adjustment structure 5. The adjustment structure 5 includes threaded holes 51, and there are two sets of threaded holes 51. The two sets of threaded holes 51 are respectively opened inside the two sides of the mounting plate 1. The adjustment structure 5 also includes bolts 52, and the bolts 52 are threaded into the inside of the threaded holes 51. A support plate 53 is attached to the middle position of the upper end of the mounting plate 1, and hinge plates 54 are attached to the outer surfaces of both sides of the upper end of the mounting plate 1. The outer surfaces of both sides of the support plate 53 are respectively hinged to the two sets of hinge plates 54. The first shim 6 is fixedly connected to the upper surface of the support plate 53, and the two sets of second shims 7 are respectively fixedly connected to the upper surfaces of the two sets of hinge plates 54. The outer surface of the upper end of the bolt 52 abuts against the outer surface of the lower end of the hinge plate 54.
[0031] In this embodiment, by rotating the bolt 52 clockwise, the bolt 52 can move upward inside the threaded hole 51, which can drive the hinge plate 54 to rotate upward and hinge at the same time, and cause the two sets of second pads 7 to rotate upward and hinge at the same time. This allows the patient lying on the first pad 6 and the second pad 7 to turn over slightly, so that the skin of the patient at the pressure point is slightly removed from the device, reducing local pressure and promoting blood circulation at the pressure point. At the same time, rotating the bolt 52 clockwise or counterclockwise can adjust the angle of the hinge plate 54.
[0032] Working principle: When using the equipment, first pull the protective plate 44 outward to disengage it from the inside of the moving groove 42. Through the torsion spring between the moving plate 43 and the protective plate 44, the protective plate 44 automatically hinges and rotates upward to be perpendicular to the outer surface of the upper end of the mounting plate 1. The four sets of protective plates 44 can protect the patient above the first pad 6 and the second pad 7, preventing the patient from falling off the equipment. At the same time, the four sets of protective plates 44 can remind the patient of the edge position of the equipment. Then, rotate the bolt 52 clockwise, so that when the bolt 52 moves upward, it drives the hinge plate 54 to hinge and rotate, and drives the two sets of second pads 7 to hinge and rotate upward. This allows the patient lying on the first pad 6 and the second pad 7 to turn slightly, reducing local pressure and promoting blood circulation in the pressure area. The staff can move the equipment to a suitable position using the casters 3. At the same time, the staff can lift the support plate 53 and the hinge plate 54 to move the patient lying on the first pad 6 and the second pad 7 to a different position. The above is the complete working principle of this utility model.
[0033] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
