Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and specifically provides a patient transfer bed. Background Technology

[0002] To reduce the burden on medical staff when transferring patients between nursing rooms and examination rooms, hospitals generally provide transfer beds. These transfer beds are small, mobile beds used for patient transport. However, currently used transfer beds in hospitals either only have a movement function, moving patients who cannot move independently from one area to another before continuing to use the transfer bed; or they transfer patients to the target area and then require multiple medical staff to move them to the target bed. Neither of these types of transfer beds is suitable for areas with specific beds, and they can easily cause secondary injury to patients, increasing the workload of medical staff. This is especially true for beds with special structures such as CT and MRI beds, where medical staff can only manually lift patients who cannot move independently to the target bed, and after treatment or examination, they still need to manually lift the patient back to the transfer bed to move them to other areas, which is extremely cumbersome. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a patient transfer bed for transferring patients who are unable or inconvenient to move independently. It allows patients to be moved to target beds such as CT or MRI beds without the need for manual lifting.

[0004] The technical solution of this utility model is as follows:

[0005] A patient transfer bed includes a support frame with casters and a mattress. The support frame includes two sets of lifting brackets, which can be lifted and lowered independently. A bed board is provided between the support frame and the bed board, and the two ends of the bed board are respectively mounted on the two lifting brackets.

[0006] In this solution, the overall height of the support frame is adjusted so that the bed board is higher than the target bed position. Then, two independently adjustable lifting brackets control the overall tilt of the bed board, allowing the patient on the bed board to be moved to the target bed position along with the mattress without manual lifting. After treatment or examination, the height of the bed board can be adjusted so that the bed board is lower than the target bed position, and then the bed board can be tilted upwards so that the patient can be easily pushed back onto the bed board along with the mattress. This solution is suitable for various target bed positions, reduces the workload of medical staff, and facilitates the transfer of patients between beds.

[0007] When the bed board tilts, if the connection point between the lifting bracket and the main board does not slide, the distance between the two lifting brackets will shorten. Normally, the distance between the two lifting brackets is fixed. To avoid interference between the tilting of the bed board and the distance between the two lifting brackets, preferably, the bed board includes a connecting plate and a main board. The connecting plate is mounted on one of the lifting brackets, and the main board is rotatably mounted on the other lifting bracket. The main board is slidably inserted into one end of the connecting plate. When the bed board tilts, the main board can slide at the end of the connecting plate to achieve overall widening or narrowing of the bed board.

[0008] Preferably, the bed board further includes a sliding frame, the main board is slidably disposed in the sliding frame, and the sliding frame is rotatably disposed on the lifting bracket.

[0009] In this solution, the mainboard can actively move away from or insert into the connecting plate by sliding within the sliding frame. Since the mainboard is the main load-bearing surface of the mattress, this design allows for better patient transfer to specialized beds such as CT or MRI beds. Specifically, the entire transfer bed is positioned outside the target bed via the frame mechanism of the transfer bed support, with the mainboard above the target bed surface. Sliding the mainboard outwards allows for in-situ bed transfer of the patient. After treatment or examination, the mainboard can be inserted from the side between the patient and the target bed surface for another in-situ transfer. Compared to relying solely on tilting the bed board to push the patient to the target bed from the side, this solution is more labor-saving and convenient.

[0010] To facilitate tilting and pushing the patient and reduce friction, the upper surface of the main board is preferably provided with raised rollers, allowing the mattress to slide and rub against the bed board while carrying the patient.

[0011] Since one method of transferring a patient back to the transfer bed is to insert the motherboard between the patient and the target bed, to avoid friction between the lower surface of the motherboard and the target bed, preferably, the lower surface of the motherboard is provided with raised rollers.

[0012] Preferably, a baffle is rotatably provided at the end of the connecting plate away from the main board, and the baffle includes a first state in which it faces downward and is perpendicular to the connecting plate, and a second state in which it faces upward and is perpendicular to the connecting plate.

[0013] In this design, the baffle can switch between two states. When the baffle is in the second state, it can prevent patients from falling off the connecting plate side during bed transfer.

[0014] Preferably, a telescopic arm is provided on the lifting bracket connected to the sliding frame. The output end of the telescopic arm is rotatably connected to the sliding frame, and the telescopic arm controls the rotation angle of the sliding frame on the lifting bracket. The telescopic arm allows for more convenient control of the angle of the sliding frame, thereby controlling the tilt angle of the main board.

[0015] Preferably, a reinforcing rod is provided at the bottom of the connecting plate. One end of the reinforcing rod is horizontally rotatably mounted at the bottom of the connecting plate, and a buckle is provided at the bottom of the sliding frame. The other end of the reinforcing rod can be engaged in the buckle. In this design, the reinforcing rod can be moved and stored without affecting the transfer operation of the transfer bed, and engaging the reinforcing rod in the buckle also enhances the strength of the bed board.

[0016] Preferably, multiple connecting arms are provided between the two lifting supports. One end of each connecting arm is rotatably connected to one lifting support, and the other end is snapped onto the other lifting support. Connecting the supporting beam lifting supports via the connecting arms strengthens the support frame. Furthermore, when it is necessary to place the entire transfer bed around the target bed, by releasing the snapping of the connecting arms that would cause interference, and rotating it for storage, the entire frame of the transfer bed can be pushed to enclose the target bed board, facilitating subsequent transfer of the patient to or from the target bed onto the transfer bed board.

[0017] Preferably, the rollers on the support frame are multiple omnidirectional wheels located at the bottom edge.

[0018] The beneficial effects of this utility model are:

[0019] This invention makes it easier for medical staff to transfer patients who cannot move independently from the transfer bed to the target bed, and also allows patients to be transferred from the target bed to the mobile bed. In particular, it is useful for transferring patients to CT beds, MRI beds and other specially constructed beds that cannot be moved, effectively avoiding the possibility of secondary injury to the patient during the transfer and reducing the workload of medical staff.

[0027] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention.

[0028] Example 1:

[0029] A type of patient transfer bed, such as Figure 1 and Figure 2 As shown, the device includes a support frame 1 with rollers 24 and a mattress 3. The support frame 1 includes two sets of lifting brackets 11, which can be lifted and lowered independently. A bed board 2 is provided between the support frame 1 and the bed board 2, and the two ends of the bed board 2 are respectively mounted on the two lifting brackets 11.

[0030] Specifically, the entire transfer bed has a rectangular shape, and all its structures are made of aluminum. The mattress can be a wooden board or an aluminum plate mattress, and the bed board 2 is also a rectangular panel. The lifting brackets 11 of the support frame 1 can be symmetrically arranged at both ends of the length or width of the rectangular bed board 2. Each set of lifting brackets 11 on one side can consist of multiple lifting rods, one of which can be a powered hydraulic telescopic rod. In this embodiment and subsequent embodiments, the lifting brackets 11 are arranged at both ends of the width direction, that is, two lifting brackets 11 are arranged on the long side for description.

[0031] When the bed board 2 tilts, if the connection point between the lifting bracket 11 and the main board 21 does not slide, the distance between the two lifting brackets 11 will shorten. Normally, the distance between the two lifting brackets 11 is fixed. To avoid interference between the tilting of the bed board 2 and the distance between the two lifting brackets 11, one connection between the bed board 2 and the lifting brackets 11 is a rotatable connection, and the other connection is a sliding connection via a sliding groove slider. This ensures that the distance between the two lifting brackets 11 remains unchanged when the bed board 2 tilts. Of course, this embodiment provides another, more preferred method, such as... Figure 2 and Figure 3As shown, the bed board 2 includes a connecting plate 22 and a main board 21. The connecting plate 22 is disposed on one of the lifting brackets 11, and the main board 21 is rotatably disposed on the other lifting bracket 11. The main board 21 is slidably inserted into one end of the connecting plate 22. The main board 21 can achieve the overall widening and narrowing of the bed board 2 by sliding at the end of the connecting plate 22.

[0032] In this embodiment, the patient is transferred while lying on a transfer bed. Upon reaching the target bed 4, the transfer bed needs to be aligned parallel to and against the long side of the target bed 4. The height of the transfer bed is then adjusted so that the bed board 2 is higher than the target bed 4. Two independently adjustable lifting brackets 11 control the overall tilt of the bed board 2, so that the edge of the bed board 2 closest to the target bed 4 is in a lower position and at the same height as the bed surface of the target bed 4. The patient can then be moved to the target bed 4 by dragging the mattress 3. After treatment or examination, when moving the patient back to the transfer bed, the height of the bed board 2 can be adjusted so that the bed board 2 is lower than the target bed 4. The bed board 2 can then be tilted upwards, making it easier to push the patient back onto the bed board 2 along with the mattress 3. This method is applicable to various target beds 4, reducing the workload of medical staff and facilitating patient transfers between beds.

[0033] Furthermore, a baffle 25 is hinged to one end of the connecting plate 22 away from the main board 21. The baffle 25 has a first state of being perpendicular to the connecting plate 22 downwards and a second state of being perpendicular to the connecting plate 22 upwards. In this embodiment, by placing the baffle 25 in the second state, the patient is prevented from falling off the other end when being transferred back to the transfer bed.

[0034] Furthermore, a reinforcing rod 12 is provided at the bottom of the connecting plate 22. One end of the reinforcing rod 12 is horizontally rotatably mounted at the bottom of the connecting plate 22, and a buckle 13 is provided at the bottom of the sliding frame 23. The other end of the reinforcing rod 12 can be engaged in the buckle 13. In this design, the reinforcing rod 12 can be moved and stored without affecting the transfer operation of the transfer bed, and engaging the reinforcing rod 12 in the buckle 13 also enhances the strength of the bed board 2.

[0035] Example 2:

[0036] In Embodiment 1, the bed board 2 is divided into a connecting plate 22 and a main plate 21, meaning the bed board 2 can be divided into two parts. The main plate 21 is the main load-bearing plate. Therefore, based on Embodiment 1, as follows... Figure 2 and Figure 3As shown, the bed board 2 also includes a sliding frame 23. The main board 21 is slidably disposed in the sliding frame 23. The surface of the main board 21 and the sliding frame 23 are respectively provided with sliding grooves and sliding rails. The sliding frame 23 is rotatably disposed on the lifting bracket 11. A plurality of connecting arms 14 are provided between the two lifting brackets 11. One end of the connecting arm 14 is rotatably connected to the lifting bracket 11 on one side, and the other end is snapped onto the lifting bracket 11 on the other side. The snapping method includes, but is not limited to, dovetail structure snapping, pin snapping, etc. The supporting beam lifting bracket 11 is connected through the connecting arms 14 to strengthen the support frame 1.

[0037] With this configuration, in addition to transferring patients in the same manner as in Example 1, this embodiment also offers more effective transfer methods, such as... Figure 4 As shown: The main board 21 can actively move away from or insert into the connecting plate 22 by sliding in the sliding frame 23. Through the frame mechanism of the transfer bed support frame 1 and adjusting the height of the bed board 2, the locking of the connecting arm 14, which may cause interference, is released. After rotation and storage, the entire frame of the transfer bed can be wrapped around the target bed board 2 by pushing the transfer bed. The main board 21 is above the bed surface of the target bed 4. By sliding the main board 21 outward, it can be pulled out, realizing the in-situ bed transfer of the patient. It should be noted that a handle can be set at the end of the main board 21 to facilitate the medical staff to pull the main board 21. At the same time, when pulling out the main board 21, one end of the mattress 3 can be manually fixed to avoid excessive friction causing the patient's position to shift and thus creating a threatening situation. After treatment or examination, the main board 21 is inserted between the patient and the bed surface of the target bed 4 from the side. After the main board 21 is reinserted into the connecting plate 22, the height adjustment and lifting bracket 11 is adjusted to realize the patient's in-situ transfer again. The transfer bed is then moved out, and the released connecting arm 14 is re-locked. Compared to relying solely on tilting the bed board 2 to push the patient from the side to the target bed 4, this method is more labor-saving and convenient. Furthermore, when using this transfer method, the reinforcing link 12 should contact the connection when pushed into the target bed 4 to avoid interference with the target bed 4.

[0038] Furthermore, in order to facilitate tilting and pushing the patient and reduce friction, preferably, the upper surface of the main board 21 is provided with raised rollers 24, so that the mattress 3 carries the patient and generates sliding friction with the bed board 2.

[0039] Furthermore, since one method of transferring the patient back to the transfer bed is to insert the mainboard 21 between the patient and the bed surface of the target bed 4, in order to avoid friction between the lower surface of the mainboard 21 and the bed surface of the target bed 4, the lower surface of the mainboard 21 is provided with protruding rollers 24. It should be noted that the rollers 24 on the upper surface and the rollers 24 on the lower surface of the mainboard 21 should be staggered to ensure the strength of the mainboard 21 while minimizing the thickness of the mainboard 21.

[0040] Furthermore, a telescopic arm 26 is provided on the lifting bracket 11 connecting the sliding frame 23. The output end of the telescopic arm 26 is rotatably connected to the sliding frame 23, and the telescopic arm 26 controls the rotation angle of the sliding frame 23 on the lifting bracket 11. The telescopic arm 26 makes it easier to control the angle of the sliding frame 23, thereby controlling the tilt angle of the main board 21.

[0041] Furthermore, the rollers 24 on the support frame 1 are multiple omnidirectional wheels arranged on the bottom edge, preferably omnidirectional wheels are arranged at the four bottom corners of the entire movable bed.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
