Detailed implementation manners

[0030] References to "embodiments" in this document mean that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0031] An embodiment of the present invention provides a patient safety transfer device, as Figures 1-12As shown in the figure, the patient safety transfer device includes: a base plate 1, and universal wheels 3 for moving are installed below the base plate 1; a vertical plate 44 fixed on the base plate 1, and a handle frame 45 for gripping is fixedly installed on the vertical plate 44; an assembly frame 5 arranged on the base plate 1 and with adjustable height, and an adjustable assembly plate 6 is slidably installed on the assembly frame 5; an installation shell 7 arranged below the assembly plate 6 and capable of lifting, and a transfer frame 8 is fixed to the bottom of the installation shell 7, and a deployable cloth belt 9 is provided on the transfer frame 8 for supporting the patient; a protection mechanism assembled on the installation shell 7; a lifting mechanism arranged on the assembly plate 6 for controlling the lifting of the installation shell 7.

[0032] In this embodiment, during use, medical staff can grip the handle frame 45 on the vertical plate 44 and use the universal wheels 3 below the base plate 1 to push the transfer device to move beside the patient's hospital bed. According to the height of the patient's hospital bed, adjust the height of the assembly plate 6 through the assembly frame 5, and then use the lifting mechanism on the assembly plate 6 to control the installation shell 7 to descend, and adjust the transfer frame 8 to an appropriate height. Unfold the cloth belt 9 on the transfer frame 8, pass the cloth belt 9 under the patient's body, and then hang and fix the cloth belt 9. Then, the lifting mechanism controls the installation shell 7 to rise, and the patient can be transferred from the operating table to the hospital bed.

[0033] This patient safety transfer device significantly reduces the dependence on manpower for transfer. For traditional transfer, 2 - 3 medical staff need to cooperate. However, this device reduces the manpower input, reduces the requirements for the operation tacit understanding and physical strength of medical staff, and a single person can also complete the transfer work relatively easily; the way that the cloth belt 9 passes under the patient's body and is fixed, combined with the protection mechanism on the installation shell 7, forms a stable support and protection system, greatly reducing the risk of falling that may be caused by manual handling.

[0034] In a further preferred embodiment of the present invention, the protection mechanism includes: concave frames 17 fixed on both sides of the mounting shell 7, with a rotating rod 18 assembled on the concave frames 17 through bearings; a protection frame 19 and a first gear 20 fixed on the rotating rod 18; a bidirectional screw rod 21 assembled in the mounting shell 7 through bearings, with an adjusting block 22 threadedly sleeved on the bidirectional screw rod 21; a rack 23 slidably mounted on the mounting shell 7 and meshing with the first gear 20, one end of the rack 23 being fixedly connected to the adjusting block 22; an assembly shell 37 provided on one side of the mounting shell 7, with a through groove 38 opened on the assembly shell 37, and a sliding frame 39 slidably mounted in the through groove 38; a connecting rod 40 assembled on the sliding frame 39 through bearings, one end of the connecting rod 40 being fixedly connected to the bidirectional screw rod 21 through a coupling; a toothed plate 41 fixed in the assembly shell 37; a second gear 42 fixed on the connecting rod 40, the second gear 42 meshing with the toothed plate 41; a guide rod 24 fixed in the mounting shell 7, the guide rod 24 passing through the adjusting block 22.

[0035] In this embodiment, when the mounting shell 7 descends, the second gear 42 on the connecting rod 40 moves downward along the toothed plate 41 in the assembly shell 37, driving the connecting rod 40 to rotate, and further driving the bidirectional screw rod 21 connected thereto to rotate. The rotation of the bidirectional screw rod 21 causes the adjusting block 22 threadedly sleeved thereon to slide along the guide rod 24, and the adjusting block 22 drives the rack 23 fixedly connected thereto to move. The rack 23 meshes with the first gear 20, driving the rotating rod 18 to rotate, and causing the protection frame 19 fixed on the rotating rod 18 to automatically unfold; when the mounting shell 7 ascends, the second gear 42 moves in the reverse direction along the toothed plate 41, driving the protection frame 19 to retract, completing the protection and evacuation protection operations.

[0036] The protection frame 19 is automatically unfolded or retracted during the ascending and descending process of the mounting shell 7 through the meshing transmission between the second gear 42 and the toothed plate 41, forming a stable enclosure structure, effectively preventing the patient from accidentally falling during transportation.

[0037] In a further preferred embodiment of the present invention, the lifting mechanism includes: a first fixing frame 25 fixed on the assembly plate 6, the bottom of the first fixing frame 25 being fixedly connected to the assembly shell 37; mounting plates 26 symmetrically fixed on the first fixing frame 25, with a winding roller 27 assembled on the mounting plates 26 through bearings, a steel wire rope 28 being provided on the winding roller 27, one end of the steel wire rope 28 passing through the assembly plate 6; a hanging frame 30 fixed on the steel wire rope 28, with a circular ring 29 provided on the hanging frame 30, the circular ring 29 being fixedly connected to the mounting shell 7; a first motor 43 fixed on the first fixing frame 25, the output shaft of the first motor 43 being fixedly connected to the shaft rod of the winding roller 27 through a coupling.

[0038] In this embodiment, during use, start the first motor 43 on the first fixing frame 25. The power is transmitted to the winding roller 27 through the coupling to drive its rotation. When the winding roller 27 rotates forward, the steel wire rope 28 is wound, and the mounting shell 7 is driven to rise steadily through the hanging frame 30 and the ring 29; when rotating in the reverse direction, the steel wire rope 28 is released, and the mounting shell 7 descends under the action of gravity. By controlling the rotation direction of the first motor 43, the height of the mounting shell 7 can be flexibly adjusted to adapt to the height differences of different hospital beds;

[0039] This lifting mechanism effectively improves the convenience and stability of the transfer operation. Compared with the traditional manual lifting method, the combination of the electrically driven winding roller 27 and the steel wire rope 28 does not require the cooperation of multiple medical staff. A single person can easily control the lifting and lowering of the mounting shell 7, reducing labor costs and operation difficulties. At the same time, the stable connection of the steel wire rope 28 with the hanging frame 30 and the ring 29, combined with the precise control of the motor, makes the lifting and lowering process of the mounting shell 7 smooth and stable, reducing the discomfort and risks caused by shaking during the transfer of patients and ensuring the safety of the transfer.

[0040] This mechanism is integrated on the assembly plate 6 and has strong coordination with other components of the transfer device. By simply controlling the first motor 43, the height adjustment of the mounting shell 7 can be quickly completed, effectively improving the transfer efficiency.

[0041] In a further preferred embodiment of the present invention, a driving mechanism for regulating the telescopic movement of the assembly plate 6 is provided on the assembly frame 5 and the base plate 1. The driving mechanism includes: a fixed shell 59 fixed on the assembly frame 5, a second one-way screw rod 60 is assembled in the fixed shell 59 through a bearing, and one end of the second one-way screw rod 60 extends into the assembly plate 6 in a threaded manner; a second fixing frame 49 fixed on the fixed shell 59, a spline rod 58 is assembled on the second fixing frame 49 through a bearing, and the spline rod 58 and the second one-way screw rod 60 are driven by a fourth bevel gear 61 engaged with each other through assembly; an installation box 50 fixed on the base plate 1, a spline cylinder 56 adapted to the spline rod 58 is assembled on one side of the installation box 50 through a bearing seat; a second motor 51 fixed in the installation box 50, a first transmission rod 52 is assembled on the second motor 51 through a coupling; a second transmission rod 54 assembled on the installation box 50 through a bearing, the second transmission rod 54 and the first transmission rod 52 are driven by a second bevel gear 55 engaged with each other through assembly; third bevel gears 57 engaged with each other through assembly are respectively fixed between the second transmission rod 54 and the spline rod 58.

[0042] In this embodiment, the second motor 51 is started, and its power is transmitted to the first transmission rod 52 through the coupling. Through the meshing transmission of the second bevel gear 55, the third bevel gear 57, and the fourth bevel gear 61 in sequence, the second one-way screw rod 60 is driven to rotate, so that the assembly plate 6 can telescopically move back and forth on the assembly frame 5 to complete the lateral position adjustment. At the same time, if it is necessary to adjust the height of the assembly frame 5, the electric hydraulic rod 4 can be started, and its output rod pushes the groove seat to rise and fall. Since the groove seat is connected to the assembly frame 5, the assembly frame 5 is driven to rise and fall synchronously; after the assembly frame 5 reaches the appropriate height, the assembly frame 5 is limited and fixed by tightening the bolts on the mounting seat to prevent it from shifting during the transfer process.

[0043] In a further preferred embodiment of the present invention, an electric hydraulic rod 4 is fixedly installed on the top of the base plate 1, and an output rod of the electric hydraulic rod 4 is fixedly installed with a groove seat for connecting the assembly frame 5, and bolts for limiting the assembly frame 5 are provided on the mounting seat.

[0044] In this embodiment, before the transfer operation, according to the heights of facilities such as the target hospital bed and the operating table, the electric hydraulic rod 4 fixed on the top of the base plate 1 is started. The output rod of the electric hydraulic rod 4 pushes the groove seat to perform vertical lifting and lowering. Since the groove seat is firmly connected to the assembly frame 5, the assembly frame 5 is driven to rise or fall synchronously.

[0045] Compared with the traditional manual adjustment or complex mechanical structure, the electric hydraulic rod 4 only needs simple operation to quickly complete the height adjustment of the assembly frame 5, greatly saving the operation time and physical consumption of medical staff.

[0046] In a further preferred embodiment of the present invention, a bracket 35 is fixedly installed on the assembly plate 6, and a guide wheel 36 for guiding the steel wire rope 28 is rotatably installed on the bracket 35.

[0047] In this embodiment, after the lifting mechanism is started, the steel wire rope 28 performs telescopic movement driven by the winding roller 27. At this time, the guide wheel 36 fixedly installed on the bracket 35 of the assembly plate 6 plays a role. The steel wire rope 28 contacts the guide wheel 36 and drives it to rotate. Under the guidance of the guide wheel 36, the steel wire rope 28 moves smoothly along the predetermined path, thereby realizing the lifting control of the installation shell 7; this guide wheel structure reduces the frictional loss during the operation of the steel wire rope 28.

[0048] In a further preferred embodiment of the present invention, a lifting ring 11 and a hook 12 are fixedly installed on the transfer rack 8, a lifting hook 13 is provided on the lifting ring 11, and both ends of the cloth belt 9 are connected to the lifting hook 13 and the hook 12 through a connecting belt 10.

[0049] In this embodiment, through simple buckling and hanging operations, the installation and fixation of the cloth belt 9 on the transfer rack 8 can be quickly completed; when the transfer is completed, simply remove the hook 13 from the eyelet 11 and separate the connecting belt 10 from the hook 12, and the cloth belt 9 can be quickly disassembled, facilitating cleaning or replacement.

[0050] This structure significantly optimizes the installation and disassembly process of the cloth belt 9, greatly reducing the operation difficulty for medical staff. Traditional fixation methods often require knotting, winding, or the use of tools, which is time-consuming and error-prone. However, through the quick connection design of the hook 13 and the eyelet 11, and the connecting belt 10 and the hook 12 in this solution, the installation time of the cloth belt 9 is significantly shortened. Even in emergency transfer scenarios, the preparation work can be efficiently completed, improving the overall transfer efficiency.

[0051] In a further preferred embodiment of the present invention, elastic bands 14 are symmetrically fixed on the cloth belt 9, and snap shells 15 and snap heads 16 that can be mutually buckled are respectively fixed on the corresponding elastic bands 14.

[0052] In this embodiment, after the patient lies steadily on the cloth belt 9, medical staff respectively pull the elastic bands 14 symmetrically arranged on both sides of the cloth belt 9 to naturally surround the patient's body. Subsequently, precisely insert the snap head 16 on one side of the elastic band 14 into the snap shell 15 of the other side of the elastic band 14. As the snap shell 15 and the snap head 16 are tightly buckled, a stable fixation structure is formed, thereby safely and reliably fixing the patient on the cloth belt 9, laying the foundation for subsequent transfer operations;

[0053] The elastic property of the elastic band 14 can automatically adjust the tightness according to the patient's body shape, avoiding poor blood circulation caused by too tight binding or patient displacement caused by too loose binding; the buckling method of the snap shell 15 and the snap head 16 is more convenient and faster than the traditional strap fixation, and the connection is firm, which can effectively prevent the fixation from failing due to bumps and vibrations during transportation, greatly reducing the risk of the patient falling.

[0054] In a further preferred embodiment of the present invention, a detachable hanging rack 71 for hanging infusion bottles is assembled on the assembly plate 6, and a telescopic adjustable adjusting plate 2 is provided on the base plate 1.

[0055] In this embodiment, when it is necessary to transfer a patient who is receiving intravenous infusion, install the detachable hanging rack 71 on the assembly plate 6, and then hang the infusion bottle on the hanging rack 71; after the transfer is completed, the hanging rack 71 can be disassembled from the assembly plate 6, which is convenient for storage and next use.

[0056] In a further preferred embodiment of the present invention, a liftable limit frame 64 is provided on the base plate 1, and an anti-slip pad 65 is fixedly installed at the bottom end of the limit frame 64.

[0057] In this embodiment, when the transfer device reaches the designated position, the limit frame 64 on the base plate 1 is activated to make it descend. As the limit frame 64 gradually descends, the anti-skid pad 65 at its bottom comes into close contact with the ground, and the anti-skid material increases the friction with the ground, so that the transfer device is firmly fixed in place; when the transfer device needs to be moved again, the limit frame 64 is controlled to rise, so that the anti-skid pad 65 is separated from the ground, and the limit state of the transfer device is released, so as to facilitate the continued transfer operation;

[0058] This structure effectively enhances the stability of the transfer device, preventing accidental slippage of the device from affecting medical staff's operations or causing discomfort or even danger to patients, and provides solid support for the transfer process.

[0059] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0060] In another embodiment of the present invention, the mounting box 50 is provided with a linkage mechanism for adjusting the lifting and lowering of the limit frame 64, and the linkage mechanism includes: a mounting frame 48 fixed to the top of the mounting box 50, a third one-way screw 62 is assembled on the mounting frame 48 through a bearing, a threaded barrel 63 is threadedly sleeved on the third one-way screw 62, and the bottom end of the threaded barrel 63 is fixedly connected to the limit frame 64; a sliding rod 66 fixed to the mounting frame 48, a sleeve block 67 is sleeved on the sliding rod 66, and one end of the sleeve block 67 is fixedly connected to the threaded barrel 63; a third transmission rod 68 assembled on the mounting frame 48 through a bearing, and the third transmission rod 68 and the third one-way screw 62 are driven by assembled fifth bevel teeth 69 that mesh with each other; and sixth bevel teeth 70 that are respectively fixed on the third transmission rod 68 and the spline barrel 56 and mesh with each other.

[0061] In this embodiment, when the second motor 51 starts to drive the spline cylinder 56 to rotate, the spline cylinder 56 drives the third transmission rod 68 to rotate synchronously through the mutually meshing sixth bevel teeth 70. The third transmission rod 68 drives the third one-way screw 62 to rotate through the mutually meshing fifth bevel teeth 69, so that the threaded cylinder 63 threadedly sleeved on the third one-way screw 62 moves linearly along the slide rod 66. Since the bottom end of the threaded cylinder 63 is fixedly connected to the limit frame 64, the lifting movement of the limit frame 64 is realized;

[0062] By linking the lifting and lowering of the limiting frame 64 with the telescopic adjustment of the assembly plate 6, medical staff can simultaneously complete the limiting fixation while adjusting the lateral position of the device.

[0063] In another embodiment of the present invention, a first one-way screw 47 is assembled in the base plate 1 through a bearing, a sleeve plate 46 is threadedly sleeved on the first one-way screw 47, an adjustment plate 2 is fixedly mounted on the sleeve plate 46, and the first one-way screw 47 and the first transmission rod 52 are equipped with first bevel teeth 53 that mesh with each other.

[0064] In this embodiment, when the second motor 51 is started to drive the spline cylinder 56 to rotate, the power is transmitted to the third one-way screw 62 through the sixth bevel gear 70, the third transmission rod 68, and the fifth bevel gear 69 in sequence, causing it to rotate. The rotation of the third one-way screw 62 drives the threaded cylinder 63 to move linearly along the slide rod 66, thereby realizing the lifting and lowering of the limit frame 64. When the assembly plate 6 needs to be extended to adjust the lateral position, the limit frame 64 drops synchronously, and its bottom anti-skid pad 65 contacts the ground to fix the device; when the assembly plate 6 is retracted, the limit frame 64 rises, releasing the fixed state and restoring the mobility of the device;

[0065] This linkage mechanism significantly improves the operational convenience and stability of the transfer device. By linking the lifting and lowering of the limit frame 64 with the telescopic adjustment of the assembly plate 6, medical staff only need to control the steering of the second motor 51 to simultaneously complete the lateral position adjustment and limit fixation of the device, without the need for additional operating steps, greatly simplifying the transfer process. At the same time, the contact between the limit frame 64 and the ground effectively prevents the device from sliding or shaking during the transfer process, providing a safer transfer environment for patients.

[0066] In another embodiment of the present invention, a reciprocating screw rod 31 is mounted on the mounting plate 26 through a bearing, and a guide rope sleeve 32 is threadedly mounted on the reciprocating screw rod 31 for the wire rope 28 to pass through; pulleys 33 are respectively fixed on the reciprocating screw rod 31 and the winding roller 27, and a transmission belt 34 is mounted on the two pulleys 33 for transmission.

[0067] In this embodiment, when the first motor 43 is started to drive the winding roller 27 to rotate, the pulley 33 on the winding roller 27 drives the pulley 33 on the reciprocating screw 31 to rotate synchronously through the transmission belt 34, so that the reciprocating screw 31 rotates. As the reciprocating screw 31 rotates, the guide rope sleeve 32 threadedly mounted thereon performs reciprocating linear motion along the screw axis. In the process of the winding roller 27 retracting and releasing the wire rope 28, the wire rope 28 passing through the guide rope sleeve 32 is evenly and orderly wound around the surface of the winding roller 27 or released from the winding roller 27 under the reciprocating guidance of the guide rope sleeve 32, so that the wire rope 28 is neatly arranged;

[0068] By linking the winding roller 27 with the reciprocating screw rod 31, the guide rope sleeve 32 automatically reciprocates during the winding and releasing of the wire rope 28, thereby avoiding the problem of local accumulation or chaotic entanglement of the wire rope 28 on the winding roller 27, extending the service life of the wire rope 28, and reducing the risk of jamming or failure caused by uneven winding.

[0069] In summary, compared with the related art, flexible movement is achieved through the base plate 1 and the casters 3, and the vertical plate 44 and the handle frame 45 are matched to facilitate the operation by medical staff; components such as the assembly frame 5, the assembly plate 6 and the electric hydraulic rod 4 form a height adjustable system, and the lifting mechanism realizes the precise lifting of the installation shell 7 by means of the first motor 43 and the steel wire rope 28; the protection mechanism utilizes the engagement of the second gear 42 and the toothed plate 41 when the installation shell 7 descends, and the protection frame 19 ensures the safety of the patient; the cloth belt 9, the elastic belt 14 and the hanging ring 11 on the transfer frame 8 and other structures firmly support the patient.

[0070] In several embodiments provided by the present application, it should be understood that the disclosed device can be implemented in other ways.
