Detailed Embodiments

[0038] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and drawings. The content mentioned in the embodiments does not limit the present invention. The present invention will be described in detail below with reference to the drawings.

[0039] As shown Figures 1 to 4 in the figure, a device for moving a patient between a fixed bed 7 and a mobile bed 8 provided by the present invention includes a frame body 1, a support module 2 provided on the frame body 1, a driving module 3 for driving the support module 2 to move back and forth, and a fixing module 4 provided on the support module 2.

[0040] In actual application of the present invention, for the convenience of movement, a moving module 12 and a locking module 13 are provided at the bottom of the frame body 1, and the locking module 13 is used to lock the moving module 12. Taking the example of moving a patient from the fixed bed 7 to the mobile bed 8 as an example, please refer to Figure 5 the following, the operation steps of the present invention are as follows:

[0041] Move the mobile bed 8 to the right side of the fixed bed 7;

[0042] A. Move the frame body 1 to one side of the fixed bed 7 / mobile bed 8 (the right side in this embodiment);

[0043] B. Control the support module 2 to extend through the driving module 3, so that the support module 2 moves onto the fixed bed 7 / mobile bed 8 and is located on one side of the patient (the right side in this embodiment);

[0044] C. Assist the patient to move onto the support module 2, and then use the fixing module 4 to fix the patient to the support module 2;

[0045] D. Control the support module 2 to retract, so that the patient is located directly above the mobile bed 8 / fixed bed 7;

[0046] E. Release the fixing module 4, and then assist the patient to leave the support module 2;

[0047] F. Control the support module 2 to reset.

[0048] Through the setting of the present invention, it enables medical staff to only turn the patient's body over, and then the support module 2 can extend into the position where the patient originally lay. Subsequently, the patient can lie stably on the support module 2 after resetting; the medical staff can then fix the patient to the support module 2 through the fixing module 4, and then make the support module 2 move to drive the patient onto the mobile bed 8. Then, after releasing the fixing module 4 of the patient and turning the patient over, the support module 2 can be separated from the mobile bed 8, and then the patient can lie flat again. By using the present invention, it enables medical staff to only turn or lift the patient a small distance, and then complete the movement of the patient through the support module 2, which is beneficial to reducing the use of manpower, and ensures that the patient will not be caused safety problems or discomfort due to the lack of coordination among multiple medical staff during the movement process.

[0049] In this embodiment, the fixing module 4 includes a winder 41, a fixing strap 42, a fastener 43 and a buckle seat 44. The winder 41 and the buckle seat 44 are spaced apart on the support module 2. One end of the fixing strap 42 is wound around the winder 41, and the fastener 43 is arranged at the other end of the fixing strap 42. The fastener 43 is used to insert into the buckle seat 44 to achieve locking.

[0050] Specifically, the specific structural principle of the fixing module 4 is similar to that of an automobile seat belt, achieving the effects of easy buckling and unlocking, making the operation of medical staff more convenient. The setting of the fixing module 4 is mainly to prevent the patient from detaching from the end of the support module 2 away from the frame 1 (i.e., the end), and there is no need to set too large a tightness. Instead, a certain elasticity needs to be set to adapt to different patients and make the patient not feel uncomfortable.

[0051] Specifically, the support module 2 is provided with a receiving groove 21, and the buckle seat 44 is movably arranged in the receiving groove 21. A retaining structure 25 is arranged between the buckle seat 44 and the receiving groove 21. The retaining structure 25 is used to force the buckle seat 44 to have a tendency to retract into the receiving groove 21. The retaining structure 25 is preferably a spring. By using the retaining structure 25, the buckle seat 44 always has a retracting tendency, that is, the output end of the buckle seat 44 always has a downward tendency, ensuring the receiving effect and providing an elasticity to cooperate with the fixation of the patient.

[0052] Specifically, the support module 2 includes a support plate 22 and a connecting plate 23. The connecting plate 23 is installed at the output end of the driving module 3. The support plate 22 is arranged on the bottom side of the connecting plate 23 and is perpendicular to the connecting plate 23. The winder 41 is arranged on the connecting plate 23, and the buckle seat 44 is arranged on the support plate 22;

[0053] The driving module 3 is rotatably provided with a gas spring 11, and the piston rod of the gas spring 11 is connected to the connecting plate 23.

[0054] The support module 2 is similar to an "L" - shaped structure. The connecting plate 23 is fixed to the driving module 3, ensuring the connection stability and driving reliability through a large contact area; while the support plate 22 is used to support the patient. Using the gas spring 11 increases the stability of the support of the support plate 22, and when the support plate 22 expands and contracts, the gas spring 11 can also adaptively adjust the length of the piston rod extending, thus ensuring the safety of the present invention.

[0055] Specifically, the number of the support plates 22 is at least two. The connecting plate 23 is provided with a screw rod 231. One end of the screw rod 231 is connected with a driving member 232. The screw rod 231 has two threads 233 with opposite directions, and the two support plates 22 are respectively screwed to the two threads 233.

[0056] Specifically, the driving member 232 can be a motor or a hand crank. By using the driving member 232 to control the rotation of the screw 231, the two support plates 22 can be controlled to approach or move away from each other, so as to adjust the width between the two support plates 22 according to patients of different heights and needs, making the present invention more flexible.

[0057] In this embodiment, a lifting module 5 is provided between the frame body 1 and the support module 2. The lifting module 5 is used to adjust the horizontal height of the support module 2. The lifting module 5 includes a support column 51, a lifting driver 52 and a lifting slider 53. The support column 51 is installed on the frame body 1, the lifting slider 53 is slidably arranged on the lifting column, the lifting driver 52 is used to drive the lifting slider 53 to lift, and the support module 2 is installed on the lifting slider 53.

[0058] In actual use, the driving module 3 can be an electric cylinder, and the lifting driver 52 is preferably a motor screw structure. Since the heights of different fixed beds 7 / movable beds 8 are different, and even some fixed beds 7 / movable beds 8 cannot adjust their heights, the present invention also provides a lifting module 5. By using the lifting module 5 to control the lifting of the support module 2, the height adaptation to the fixed bed 7 and the movable bed 8 is realized, making the movement of the patient safer.

[0059] Specifically, the support module 2 is provided with a detector 20. Step C specifically includes:

[0060] C1. Using the detector 20 to detect the height of the fixed bed 7;

[0061] C2. According to the height of the fixed bed 7, controlling the lifting driver 52 to act so that the support module 2 is adjusted to a height suitable for the fixed bed 7;

[0062] C3. Using the detector 20 to detect the distance between the support module 2 and the patient;

[0063] C4. According to the distance between the support module 2 and the patient, controlling the driving module 3 to act to control the extending length of the support module 2.

[0064] The detector 20 can be a vision camera, but preferably includes an infrared transceiver. Taking the infrared transceiver as an example, the position of the patient and the heights of the fixed bed 7 and the movable bed 8 are obtained through the infrared transceiver. For example, the position of the patient is obtained through the body temperature, and the position of the fixed bed 7 / movable bed 8 is obtained through the distance at which the infrared is reflected. The setting of the detector 20 is beneficial for the present invention to automatically determine the position of the patient, the height difference of the fixed bed 7 / movable bed 8, etc., so as to achieve the effect of adaptively lifting and moving the patient.

[0065] Therefore, step D of the present invention specifically includes:

[0066] D1. Using the detector 20 to obtain the height of the moving bed 8;

[0067] D2. Use the drive module 3 to control the movement of the support module 2 so that the support module 2 and the patient are away from the top of the fixed bed 7;

[0068] D3. According to the height of the moving bed 8, use the lifting module 5 to adjust the horizontal height of the supporting module 2 until the supporting module 2 conflicts with the moving bed 8.

[0069] In this embodiment, the present invention further includes an auxiliary frame 6, a first connection structure 24 is provided at the end of the support module 2, the auxiliary frame 6 is provided with a telescopic module 61, the telescopic module 61 is provided with a second connection structure 62, and the first connection structure 24 and the second connection structure 62 are detachably connected.

[0070] The auxiliary frame 6 is specially used for moving overweight patients. Since the support module 2 of the present invention is arranged on one side of the frame 1, there is a phenomenon of unbalanced force. For patients with smaller weight (for example, less than 80 kg according to the manufacturing materials of the present invention, etc.), the patient can be directly lifted up by the support module 2 for movement. However, if the patient weighs 90 kg or even 100 kg, there is a probability of rollover accident with the frame 1 alone. In this case, the present invention needs to use the auxiliary frame 6, that is, the auxiliary frame 6 is arranged on the left side (still with Figure 4 For example), when the support module 2 is extended to the fixed bed 7 and the patient lies on the support module 2, the telescopic module 61 of the auxiliary frame 6 will extend and dock with the support module 2 through the first connecting structure 24 and the second connecting structure 62. The auxiliary frame 6 and the frame body 1 form a whole to balance the center of gravity and ensure the safe movement of the patient.

[0071] The auxiliary frame 6 may also be provided with a lifting module 5, and the lifting module 5 and the telescopic module 61 of the auxiliary frame 6 may be manually controlled to save costs; or another invention may be directly used as the auxiliary frame 6. The first connecting structure 24 and the second connecting structure 62 may adopt conventional structures, such as locks, etc., in order to ensure reliable connection between the supporting module 2 and the telescopic module 61 and easy unlocking.

[0072] Specifically, a damper 63 is provided between the telescopic module 61 and the auxiliary frame 6 to ensure the balance and stability of the auxiliary frame 6 .

[0073] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention is disclosed above in the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the relevant art can, without departing from the technical solution of the present invention, make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes. However, as long as they do not depart from the technical solution content of the present invention, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical means of the present invention shall fall within the scope of the technical solution of the present invention.
