Description

Technical Field

[0001] This utility model relates to a turning bed that can be rotated at any angle, belonging to the field of medical equipment technology. Background Technology

[0002] Regular, targeted turning is crucial for critically ill, disabled elderly, and patients with fractures. For these groups, remaining in one position for extended periods can lead to serious complications such as bedsores, lung and urinary tract infections, and often even death. In clinical practice, patients typically need to be turned approximately every two hours, and often, depending on their condition, they are turned to specific angles for therapeutic purposes, such as the prone position. This position is highly effective for draining sputum in patients with lung infections, allowing for rapid infection control and thus becoming the gold standard for treating various severe pneumonias. Current hospital bed structures dictate that at least two to three people are needed to perform turning, and sometimes up to seven for intubated patients. Furthermore, each turning requires numerous positioning pads to maintain the specific angle, making each turn very time-consuming and labor-intensive. Poor coordination during turning can even cause iatrogenic injuries. Summary of the Invention

[0003] The technical problem to be solved by this utility model is: how to turn a patient who needs to be turned over by a single person or by an automatic method.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is to provide a reversible bed that can be rotated at any angle. The bed features two bed support frames, with a reversible frame between them. The middle positions of both ends of the reversible frame are rotatably connected to the two bed support frames via pivots. A mattress frame is fixed on the reversible frame, and a reversible support is detachably connected to the upper and lower parts of the mattress frame. Each reversible support is connected to both sides of the mattress frame in the direction of rotation, with at least one side being detachably connected. The bed support frames are equipped with locking devices that allow the reversible frame to be fixed after rotating at any angle. Both the mattress frame and the reversible frame have a U-shaped structure, with the mattress frame housed within the frame of the reversible frame.

[0005] Preferably, a first motor for driving the bed tilting frame to tilt is fixed on one of the bed support frames.

[0041] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] This utility model provides a turning bed that can be rotated at any angle, such as... Figure 1 As shown, it includes two bed support frames 1, with a bed flip frame 2 between them. The middle positions of both ends of the bed flip frame 2 are rotatably connected to the two bed support frames 1 via pivots 22. A mattress frame is fixed on the bed flip frame 2. A flip support 3 is detachably connected to the upper and lower parts of the mattress frame, and each flip support 3 has two sides connected to the two sides of the mattress frame in the flipping direction, with at least one side being detachably connected. The bed support frame 1 is provided with a locking device that allows the bed flip frame 2 to be fixed after flipping at any angle. In this embodiment, as... Figure 2 As shown, the pivot 22 is a short cylindrical rod, and the two ends of the bed tilting frame 2 are welded to the two pivots 22 or integrally formed. In this embodiment, the mattress frame is a fixed structure that cannot be adjusted at the head and tail.

[0044] In another embodiment, the bottoms of the two bed support frames 1 can also be welded together by a connecting rod to form an integral bed frame.

[0045] In another embodiment, both bed support frames 1 are height-adjustable structures. Bed support frames 1 with height-adjustable structures are existing technology and will not be described in detail.

[0046] A first motor 21 for driving the bed tilting frame 2 to tilt is fixed on either of the two bed support frames 1. The rotating end of the first motor 21 passes through the bed support frame 1 and is coaxially and fixedly connected to the rotating shaft 22. The first motor 21 includes a locking device and is a self-locking motor (Note: A self-locking motor is a specially designed DC motor whose core feature is automatic locking. When the motor torque reaches a preset value, it can automatically maintain the current state, i.e., stop or run, without relying on an external braking device).

[0047] like Figure 3 As shown, in order to better enable the rotating end of the first motor 21 to drive the bed tilting frame 2 to rotate, in this embodiment, a limiting plate 212 is welded or integrally formed and connected to the motor shaft 211 at the rotating end of the first motor 21. The motor shaft 211 and the limiting plate 212 are perpendicular to each other, and the limiting plate 212 is welded or fastened to the end of the bed tilting frame 2 near the first motor 21 by screws. At the same time, the motor shaft 211 and the shaft 22 are coaxial.

[0048] like Figure 1 As shown, both the mattress frame and the bed flipping frame 2 have a U-shaped structure, with the mattress frame placed inside the frame of the bed flipping frame 2.

[0049] like Figure 5 , Figure 6As shown, the flip-up support 3 includes an inner liner 31 and multiple straps 32. One end of each strap 32 is fixedly connected to one side of the mattress frame in the flip-up direction, and the other end is detachably connected to the other side of the mattress frame in the flip-up direction. Alternatively, both ends of each strap 32 can be detachably connected to both sides of the mattress frame in the flip-up direction. The inner liner 31 is located between the mattress frame and the straps 32. The ends of the straps 32 that are detachably connected to the mattress frame have buckles, and the mattress frame has insertion holes 23 at the detachable connection points of the straps 32. The buckles and insertion holes 23 are matched and connected in a snap-fit ​​manner, similar to the interlocking connection of backpack straps, helmet straps, or car seat belts. A head opening 311 is provided near the head on the inner liner 31 to facilitate head support and breathing when the patient is prone, allowing the mouth and nose to be exposed.

[0050] The inner liner 31 can be designed in various sizes according to different widths to be used by patients of different body types. The inner liner 31 can also be 3D printed to match the size of the patient's body type, so that the inner liner 31 can wrap around the patient while the two ends of the inner liner 31 in the width direction contact the sides of the mattress frame, avoiding direct contact between the patient and the strap 32.

[0051] The lining 31 on the bottom of the mattress frame is preferably a transparent inflatable pad so that medical staff can view the patient.

[0052] To ensure a better connection and prevent the lining 31 from slipping, the inner sides of the multiple straps 32 and the positions on the lining 31 that contact the multiple straps 32 are respectively provided with the hook and loop sides of Velcro, so that the two will not move relative to each other due to patient displacement.

[0053] In addition, for better folding and aesthetic reasons when not in use, and to save space, the same number of sockets 23 are provided on the back of the mattress frame, corresponding to the sockets 23 on the front of the mattress frame. When not in use, the straps 32 are wrapped around the back of the mattress frame and inserted into the corresponding sockets 23. Figure 5 As shown.

[0054] The usage process of this utility model is as follows:

[0055] The patient lies supine on the inner lining 31 of the bottom flip-up support 3. The inner lining 31 (similar to a mattress, which can be made of lightweight foam material or a foam material customized by the patient) is laid on the ventral side of the patient's body. Multiple straps 32 are wrapped around the outside of the inner lining 31 and fastened to the upper surface of the mattress frame, thereby securing the inner lining 31 to the front of the patient's body. After the first motor 21 is powered on, the start and stop of the first motor 21 are controlled by a switch, thereby controlling the flip-up frame 2 to flip to the angle required by the patient, meeting the needs of the patient in various turning positions (supine, prone, lateral, lateral supine, lateral prone).

[0056] Additionally, the inner liner 31 of the upper flip-up support 3 can also be an inflatable mattress. When the patient is flipped over (in a prone position), the air mattress (inner liner 31) on the back can be deflated appropriately, or the air mattress (inner liner 31) on the abdomen can be deflated appropriately, creating a gap between the patient and the inner liner 31 to prevent prolonged pressure on the body and the resulting complications. At this point, if the multiple straps 32 on the back are removed and the inner liner 31 on the back is taken off, the patient's back can be exposed, allowing medical staff to perform medical procedures on the patient's back if necessary.

[0057] Similarly, when the patient rolls to a side-lying or other position, the air mattress on the back or abdomen can be deflated appropriately to reduce pressure on the patient's front and back sides.

[0058] Multiple through holes can also be provided on the liner 31 (these through holes are not connected to the air cavity inside the liner 31) to facilitate the doctor's surgical operation.

[0059] Example 2

[0060] In this embodiment, as Figure 4 As shown, the locking device includes a first tilting limiting hole 111 on any one of the bed support frames 1, a second tilting limiting hole 213 on one end of the bed tilting frame 2, and a pin or screw. Multiple first tilting limiting holes 111 or second tilting limiting holes 213 are provided (i.e., one type of first tilting limiting hole 111 and the other type of second tilting limiting hole 213 has multiple holes, and the other type has at least one hole), and they are evenly distributed along the outer circumference of one end of the rotating shaft 22. When using a pin for limiting, the pin is inserted into the first tilting limiting hole 111 and the second tilting limiting hole 213; when using a screw for limiting, the screw is screwed into the first tilting limiting hole 111 and the second tilting limiting hole 213 through its thread. At least one of the first tilting limiting holes 111 and the second tilting limiting hole 213 has an internal thread.

[0061] When in use, the bed can be manually flipped to the required angle by flipping the bed frame 2. Then, the pin can be manually inserted into the first flipping limit hole 111 and the second flipping limit hole 213 corresponding to that angle, or the bolt can be screwed into the first flipping limit hole 111 and the second flipping limit hole 213 corresponding to that angle.

[0062] Everything else is the same as in Example 1.

[0063] Example 3

[0064] In this embodiment, as Figure 7As shown, the flip-up support 3 is an inflatable mattress 33. The two sides of the inflatable mattress 33 are connected to the flip-up sides of the mattress frame, and at least one side is detachably connected. The inflatable mattress 33 has a square opening in the middle or at two positions near the middle. Multiple spring straps 331 are provided in the square opening. The two ends of each spring strap 331 are connected (sewn or glued) to the two sides of the opening near the flip-up direction of the bed flip-up frame 2. A head hole 311 is provided at the head end of the inflatable mattress 33. Multiple ventilation holes 333 are evenly distributed around the square opening and around the head hole 311 on the inflatable mattress 33. Multiple buckles 331 (which may have nylon straps similar to backpack straps, one end sewn to the inflatable mattress 33 and the other end connected to the buckle 331) are glued or sewn on at least one side of the inflatable mattress 33 at the position where it is connected to the flip-up side of the mattress frame. The buckles 331 match the holes 23 on the bed flip-up frame 2.

[0065] When one side of the inflatable mattress 33 is fixedly connected to the flip-up side of the mattress frame, and the other side of the inflatable mattress 33 is inserted into the other flip-up side of the mattress frame, the same number of insertion holes 23 can be provided on the back of the mattress frame corresponding to the positions of the insertion holes 23 on the front of the mattress frame. When not in use, one side of the inflatable mattress 33 is wrapped around the back of the mattress frame in reverse, and the buckle 331 is inserted into the corresponding insertion hole 23.

[0066] The usage process of this utility model is as follows:

[0067] Before use, the inflatable pad 33 (i.e. the bottom flip-up support 3) on the lower surface of the mattress frame is inserted into the socket 23 on the lower surface of the mattress frame through the buckle 331.

[0068] When in use, the patient lies supine on the bottom inflatable pad 33 (i.e., the bottom flip support 3), and another inflatable pad 33 (i.e., the top flip support 3) is placed on the patient. The buckle 331 on the side of the inflatable pad 33 is inserted into the hole 23 on the upper surface of the mattress frame. Then the inflatable pad 33 is inflated to limit the patient's position.

[0069] After the patient is turned over (in a prone position), the air cushion 33 on the back or abdomen can be deflated appropriately to create a gap between the patient and the air cushion 33, preventing prolonged pressure on the body and potential complications. At this point, removing the air cushion 33 from the back exposes the patient's back, allowing medical staff to perform necessary procedures.

[0070] Everything else is the same as in Example 1.

[0071] Example 4

[0072] In this embodiment, the mattress frame of this utility model can also be an adjustable bed frame 4, such as... Figure 9As shown, the adjustable bed frame 4 includes a first section 41, a second section 42, a third section 43, and a fourth section 44 that are sequentially connected and can be flipped over each other. The two sides of the second section 42 are fixed to the flip-over sides of the bed tilting frame 2. The first section 41, the third section 43, and the fourth section 44 are connected to a drive device that drives their flipping. The flipping of the first section 41, the second section 42, the third section 43, and the fourth section 44 is connected by hinges or by a rotating shaft. The first section 41 and the third section 43 can only flip upwards relative to the second section 42, and the fourth section 44 can only flip downwards relative to the third section 43. The two sides of the second section 42 of the adjustable bed frame 4 are fixed to the inner wall of the bed tilting frame 2.

[0073] The drive unit includes two head cylinders 61, two tail cylinders 62, and two connecting rods 63. One end of each head cylinder 61 is movably connected to both sides of the bottom surface of the first segment 41, and the other end is movably connected to a head cylinder mounting plate 24, which is welded to the head end of the bed tilting frame 2. One end of each tail cylinder 62 is movably connected to both sides of the bottom surface of the third segment 43, and the other end is movably connected to a tail cylinder mounting plate 25, which is welded to the tail end of the bed tilting frame 2. One end of each connecting rod 63 is movably connected to both sides of the bottom surface of the fourth segment 44, and the other end is movably connected to the two tilting sides of the bed tilting frame 2 near the tail. All of the above movable connections are either hinged connections or rotatable connections via bearings.

[0074] When the first segment 41, the second segment 42, the third segment 43, and the fourth segment 44 are all laid flat, the position on the connecting rod 63 that connects to the fourth segment 44 is closer to the tail cylinder mounting plate 25 than the position on the connecting rod 63 that connects to the bed tilting frame 2.

[0075] When in use, when the patient needs to sit up or lean back, the head cylinder 61 is energized and activated, controlling the first segment 41 to rotate along the side of the second segment 42. When the desired angle is reached, the switch is turned off. When the patient needs to raise their legs, the tail cylinder 62 is energized and activated, controlling the third segment 43 to rotate along the side of the second segment 42. At the same time, the third segment 43 drives the fourth segment 44 to rotate. When the desired angle is reached, the switch is turned off.

[0076] Everything else is the same as in Example 1.

[0077] Example 5

[0078] In this embodiment, as Figure 2As shown, the bottom of the bed tilting frame 2 is fixed with first support plates 26 protruding into the bed tilting frame 2, located directly below the sides of the first segment 41, the third segment 43, and the fourth segment 44. The top of the bed tilting frame 2 is rotatably connected with second support plates 27, located on both sides of the first segment 41, the third segment 43, and the fourth segment 44. The second support plates 27 have two states after rotation: one state is that the second support plates 27 are located on the outer sides of the first segment 41, the third segment 43, and the fourth segment 44, and the other state is that the second support plates 27 are located directly above the sides of the first segment 41, the third segment 43, and the fourth segment 44.

[0079] The first support plate 26 supports the adjustable bed frame 4 when the patient is supine, preventing the patient's weight from causing the drive mechanism of the adjustable bed frame 4 to become tense and prematurely damaged. The second support plate 27 supports the adjustable bed frame 4 when the patient is prone, also preventing the patient's weight from causing the drive mechanism of the adjustable bed frame 4 to become tense and prematurely damaged.

[0080] When the patient needs to adjust the adjustable bed frame 4 to raise the first segment 41 or the third segment 43 and the fourth segment 44, the second support plate 27 needs to be rotated so that the second support plate 27 is located on the outer side of the first segment 41, the third segment 43, and the fourth segment 44, and the adjustable bed frame 4 can be operated. When the patient needs to lie prone, the second support plate 27 needs to be rotated so that the second support plate 27 is located directly above the first segment 41, the third segment 43, and the fourth segment 44, so as to better support the adjustable bed frame 4.

[0081] Everything else is the same as in Example 4.

[0082] Example 6

[0083] In this embodiment, as Figure 8 As shown, the drive device includes a hanger 51, with both ends of the hanger 51 detachably fixed to two bed support frames 1. Three second motors 52 are provided in the middle of the hanger 51. The rotating end of each second motor 52 is fixedly connected to the middle of the steel wire 54. The two ends of the steel wire 54 are detachably connected to the two ends of the adjustable bed frame 4 on the side away from the flip axis (for example, a hook is connected to the end of the steel wire 54, and rings are provided at the positions where the steel wire 54 is connected on the adjustable bed frame 4. When in use, the hook at the end of each steel wire 54 hooks onto the corresponding ring of the adjustable bed frame 4).

[0084] Three extension rods 53 perpendicular to the hanger 51 can also be installed on the top of the hanger 51. The extension rods 53 are all groove-shaped structures with the opening groove located at the top. Each steel wire 54 is placed in its corresponding opening groove. Rollers are installed at both ends of each extension rod 53 to facilitate the transmission of the steel wire 54. The drive end of the second motor 52 is parallel to the top of the hanger 51.

[0085] The top of the two bed support frames 1 is hollow. A row of through holes is provided on the two bed support frames 1 along their height direction. At least one through hole is provided at both ends of the hanger 51. The two ends of the hanger 51 are inserted into the two bed support frames 1 and the height of the hanger 51 can be fixed by the pin limit.

[0086] The second motor 52 is a self-locking motor. The winding shaft (i.e., the rotating end) of all the second motors 52 is perpendicular to the pulling direction of the steel wire.

[0087] In use, the two ends of the suspension frame 51 are inserted into the two bed support frames 1, and the height of the suspension frame 51 is adjusted. When the patient needs to sit up or lean back, the second motor 52 connected to the head is powered on and started, thereby winding the steel wire 54. This causes the two ends of the steel wire 54 to pull the first segment 41 to flip along one side of the second segment 42. When the desired angle is reached, the switch of the second motor 52 at that position is turned off. When the patient needs to arch their knees, the second motor 52 in the middle position is powered on and started, thereby winding the steel wire 54 it controls. This causes the two ends of the steel wire 54 at that position to pull the third segment 43 to flip along one side of the second segment 42. At the same time, the third segment 43 drives the fourth segment 44 to move slightly towards the head. When the bed is rotated to the desired angle, the second motor 52 switch at that position can be turned off. When the patient needs to lift their feet, the second motor 52 at the tail end is energized and started, thereby winding the steel wire 54 it controls. This causes the ends of the fourth segment 44 at that position to pull upwards, thereby causing the third segment 43 to rotate along one side of the second segment 42. Since the fourth segment 44 can only rotate downwards relative to the third segment 43, the third segment 43 and the fourth segment 44 always remain in a flat state. When the end of the fourth segment 44 is raised to the desired height, the second motor 52 switch at that position can be turned off. When the patient needs to lie down for a long time, such as to sleep, the hanger 51 and the steel wire 54 can be removed from the adjustable bed frame 4.

[0088] Everything else is the same as in Example 4.

[0089] Example 7

[0090] In this embodiment, as Figure 10As shown, the drive device includes a third motor 64 and a fourth motor 65. The drive end of the third motor 64 is fixedly connected to the first segment 41 and is coaxial with the flipping shaft of the first segment 41 at one end of the second segment 42. The drive end of the fourth motor 65 is fixedly connected to the third segment 43 and is coaxial with the flipping shaft of the third segment 43 at the other end of the second segment 42. Both the third motor 64 and the fourth motor 65 are self-locking motors.

[0091] In use, when the patient needs to sit up or lean back, the third motor 64 is powered on and started, driving the first segment 41 to rotate along one side of the second segment 42. When the desired angle is reached, the switch of the third motor 64 can be turned off.
