DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention.

[0026] Example 1

[0027] This embodiment discloses a medical transfer bed that is easy to disassemble and clean, and is used to transfer patients between different locations. At the same time, it improves the problem that the transfer cloth 6 of the existing transfer bed is difficult to disassemble.

[0028] Please refer to Figures 1-6, including a bed frame 1, the upper side of the bed frame 1 is slidably connected to a bed board 2, the bed board 2 adopts a layered structure design: the bottom layer is a honeycomb aluminum plate (bending strength ≥180MPa); the middle layer adopts a high-density PE support frame (hollow weight reduction design); the surface layer is selected from medical PVC one-piece molding (antibacterial rate ≥99%, easy to wipe and disinfect), the bed frame 1 is fixed with two pairs of first mounting frames 3, the first mounting frames 3 are located below the bed board 2, and a cloth rolling roller 4 is rotatably connected between the two first mounting frames 3 on the front side and between the two first mounting frames 3 on the rear side, and the cloth rolling roller 4 is located below the bed board 2. The cloth-winding roller 4 is detachably mounted with a snap plate 5, and a transfer cloth 6 is fixedly connected between the two snap plates 5. The transfer cloth 6 is made of nylon. Initially, part of the transfer cloth 6 is wound around the two cloth-winding rollers 4. In order to conveniently display the structure of the cloth-winding roller 4, the transfer cloth 6 wrapped around the cloth-winding roller 4 is not drawn in the figure. The transfer cloth 6 passes around the upper side of the bed board 2. The bed frame 1 is fixedly connected to a first servo motor 7 and two second servo motors 8. The output shaft of the first servo motor 7 and the bed board 2 are driven by a rack and pinion, and the output shaft of the second servo motor 8 and the corresponding cloth-winding roller 4 are driven by a gear ring.

[0029] Please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The cloth rolling roller 4 consists of a first half roller 41 and a second half roller 42. The cloth rolling roller 4 is provided with three card slots 401 (this number is not a fixed value and can be adjusted as needed, and the same applies to the specific number mentioned later). The card slot 401 contains an inserting portion 4011 and a blocking portion 4012. The longitudinal section of the inserting portion 4011 is rectangular, and the longitudinal section of the blocking portion 4012 is T-shaped. The snap plate 5 consists of a connecting portion 502 and three locking portions 501. The longitudinal section of the locking portion 501 is T-shaped. The number of the locking portions 501 is equal to the number of the card slots 401. The shape of the longitudinal section of the blocking portion 4012 is consistent with the shape of the longitudinal section of the locking portion 501, so that the locking portion 501 can be inserted into the blocking portion 4012 for connection.

[0030] Working process: When using this device to transport a patient, first push this device to the side of the bed where the patient is, so that the front side of this device is close to the bed where the patient is, and then start the first servo motor 7 and the two second servo motors 8. The output shaft of the first servo motor 7 drives the bed board 2 to move forward through the gear rack, and the two second servo motors 8 respectively drive the corresponding cloth winding rollers 4 to rotate through the gear ring. The front cloth winding roller 4 releases the transfer cloth 6 on it, and the rear cloth winding roller 4 winds the transfer cloth 6 thereon, and the rotation speed of the front cloth winding roller 4 is greater than that of the rear cloth winding roller 4, so that the part of the transfer cloth 6 located on the upper side of the bed board 2 moves backward relative to the bed board 2, and then the bed board 2 is inserted under the patient's body, and then the patient is transferred to the upper side of the bed board 2 through the movement of the transfer cloth 6. At this time, the second servo motor 8 on the front side stops working, and the rotation direction of the output shaft of the first servo motor 7 changes, driving the bed board 2 to move backward, while the second servo motor 8 on the rear side continues to drive After the bed board 2 returns to its original position, the first servo motor 7 and the two second servo motors 8 stop working, and the patient's transfer is completed.

[0031] When the transfer cloth 6 is contaminated and needs to be replaced, first wrap the entire transfer cloth 6 around one of the cloth rollers 4, then slide the snap plate 5 on the cloth roller 4 that is not wrapped with the transfer cloth 6 to the left, so that the locking portion 501 slides from the blocking portion 4012 to the insertion portion 4011, then remove the snap plate 5 from the slot 401, and then remove the snap plate 5 on the other cloth roller 4 in the same way, and install the clean transfer cloth 6 on it.

[0032] Example 2

[0033] This embodiment discloses a medical transfer bed that is easy to disassemble and clean. Based on the embodiment 1, the installation and disassembly between the cloth rolling roller 4 and the snap plate 5 are further accelerated.

[0034] Please refer to Figure 5 and Figure 6, the cloth winding roller 4 is slidably connected with three locking buckles 9. The number of the locking buckles 9 is equal to the number of the card slots 401. The locking buckle 9 is in a figure-eight shape. A spring 10 is arranged between the locking buckle 9 and the adjacent cloth winding roller 4. The locking buckle 9 is used to block the locking part 501, so as to prevent the locking part 501 from sliding out of the blocking part 4012 during normal use.

[0035] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 , the cloth winding roller 4 is slidably connected with a control rod 11. The axis of the cloth winding roller 4 and the axis of the control rod 11 coincide. The control rod 11 is provided with three extrusion grooves 1101. The number of the extrusion grooves 1101 is equal to the number of the locking buckles 9. The extrusion grooves 1101 and the corresponding locking buckles 9 are mutually extruded, so as to change the position of the locking buckle 9 when the control rod 11 slides. Two electric push rods 12 are fixedly connected to the right side of the bed frame 1. The telescopic ends of the electric push rods 12 are rotatably connected with the corresponding control rods 11. The locking buckle 9 and the buckle plate 5 are mutually extruded. The spring 10 is always in a compressed state to provide power for the locking buckle 9 to push the buckle plate 5 out of the card slot 401.

[0036] Please refer to Figure 5 and [[ID=十七]] Figure 6 , the control rod 11 is fixedly connected with three push blocks 13. The number of the push blocks 13 is equal to the number of the locking parts 501. The push blocks 13 are slidably connected with the cloth winding roller 4. The push blocks 13 are used to push the locking parts 501 to move, so as to push the locking parts 501 from the blocking part 4012 to the insertion part 4011. The extrusion groove 1101 is composed of a straight part and an inclined part. The length of the inclined part of the extrusion groove 1101 on the axis of the control rod 11 is less than the length between the push block 13 and the corresponding blocking part 4012, so that the push block 13 can push the locking part 501 to move after the control rod 11 squeezes open the locking buckle 9.

[0037] Working process: When disassembling the snap plate 5, start the electric push rod 12, the telescopic end of the electric push rod 12 drives the corresponding control rod 11 to move, and the extrusion groove 1101 of the control rod 11 squeezes the corresponding locking buckle 9, so that the locking buckle 9 moves and compresses the corresponding spring 10. When the locking buckle 9 is separated from the locking portion 501, the push block 13 contacts the locking portion 501 and pushes the locking portion 501 to move, thereby pushing the locking portion 501 from the blocking portion 4012 to the insertion portion 4011. After that, the telescopic end of the electric push rod 12 retracts and drives the control rod 11 to reset. After the control rod 11 returns to its original position The locking buckle 9 returns to its original position under the action of the corresponding spring 10. At this time, the locking buckle 9 pushes the locking part 501 out of the insertion part 4011. At this point, the snap plate 5 and the cloth roller 4 are separated. Then, a new transfer cloth 6 is installed, so that the locking part 501 on the new snap plate 5 squeezes the locking buckle 9, and then the locking part 501 is moved so that the locking part 501 enters the insertion part 4011. When the locking part 501 is separated from the locking buckle 9, the locking buckle 9 returns to its original position under the action of the corresponding spring 10 to lock the locking part 501, thereby preventing the locking part 501 from slipping out of the insertion part 4011 during normal use.

[0038] Example 3

[0039] This embodiment discloses a medical transfer bed that is easy to disassemble and clean, which is a further improvement on the basis of the first embodiment.

[0040] Please refer to Figure 1-Figure 3 The bed frame 1 is fixedly connected to two second mounting frames 14, and a cleaning seat 15 is hinged on the upper side of the second mounting frame 14. The cleaning seat 15 is detachably installed with a cleaning strip 16. The cleaning strip 16 is used to clean the transfer cloth 6. The surface material of the cleaning strip 16 can be sponge or cloth. When in use, the cleaning strip 16 is soaked in disinfectant so that the cleaning strip 16 can not only wipe the stains on the surface of the transfer cloth 6, but also disinfect the transfer cloth 6.

[0041] Please refer to Figure 2 and Figure 3 The bed frame 1 is hinged with an electromagnetic push rod 17, and the telescopic end of the electromagnetic push rod 17 is hinged to the cleaning seat 15. The electromagnetic push rod 17 controls the contact and separation of the cleaning bar 16 and the transfer cloth 6, thereby preventing impurities accumulated on the cleaning bar 16 from contaminating the transfer cloth 6 again.

[0042] Working process: When the transfer cloth 6 does not need to be deeply cleaned after use, the surface of the transfer cloth 6 is cleaned with the cleaning strip 16 before the transfer cloth 6 is wound on the cloth roller 4 on the front side. When the transfer cloth 6 is released from the cloth roller 4 on the front side, the electromagnetic push rod 17 is started, and the telescopic end of the electromagnetic push rod 17 contracts. The telescopic end of the electromagnetic push rod 17 pulls the cleaning seat 15 to rotate, and the cleaning seat 15 drives the cleaning strip 16 to rotate, thereby separating the cleaning strip 16 from the transfer cloth 6, thereby preventing the transfer cloth 6 from carrying away impurities attached to the front side of the cleaning strip 16 and contaminating it when it moves.

[0043] Example 4

[0044] This embodiment discloses a medical transfer bed that is easy to disassemble and clean. Based on the embodiment 1, the shape of the bed plate 2 is further improved to reduce the wear between the transfer cloth 6 and the bed plate 2.

[0045] Please refer to Figure 2-Figure 4 The two sides of the longitudinal section of the bed board 2 are arcs, which are used to allow the transfer cloth 6 to slide along them.

[0046] Example 5

[0047] This embodiment discloses a medical transfer bed that is easy to disassemble and clean. Based on the second embodiment, the shape of the locking buckle 9 is further improved so that the locking buckle 9 can push the locking portion 501 into the blocking portion 4012.

[0048] Please refer to Figure 6 , a slope 901 is provided on the side of the locking buckle 9 close to the corresponding blocking portion 4012. After the locking portion 501 moves to the blocking portion 4012, if the locking portion 501 is still partially located in the insertion portion 4011, the slope 901 of the locking buckle 9 will squeeze the locking portion 501 to move into the blocking portion 4012, so that the locking portion 501 completely enters the blocking portion 4012, so that there is no need to manually calibrate the snap plate 5 when installing it, further improving the installation speed and installation accuracy of the snap plate 5.

[0049] While the disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised which do not depart from the scope of the invention.
