Through the set extension plates 9, if the patient needs emergency treatment during the transport process, such as cardiopulmonary resuscitation, the medical staff can kneel on the extension plates 9 to perform cardiopulmonary resuscitation on the patient, which greatly increases the overall practicality of the device; During operation, when it is necessary to transfer a patient, it is only necessary to place the patient to be transferred on the upper part of the bed board 5, and then unlock the lock of the self-locking universal wheel 3, and then the entire device can be moved by pushing the device to achieve the transfer of the patient. After arriving at the destination ward, it is only necessary to re-lock the self-locking universal wheel 3, and then transfer the patient to the bed in the ward. It is convenient, fast, simple and practical.

[0023] The automatic bed sheet changing mechanism 11 comprises a through slot 2 1101, which is opened through one side of the supporting box 1, a rotating shaft 1102 is arranged inside the through slot 2 1101, a rotating shaft 1103 is rotatably installed inside the supporting box 1, a storage roller 1112 and a winding roller 1113 are respectively installed on the outer surfaces of the rotating shaft 1102 and the rotating shaft 2 1103, and the outer surfaces of the storage roller 1112 and the winding roller 1113 are wound with bed sheets 10, and the automatic bed sheet changing mechanism 11 is set for fast replacement of bed sheets 10, wherein a fixing plate 2 1108 is fixedly installed on both side surfaces of the bed frame 4, a mounting shaft 1109 is rotatably installed inside the fixing plate 2 1108, and a guide roller 1110 and a guide roller 2 1111 are installed between the mounting shaft 1109; The bottom surfaces of the headboard baffle 1 6 and the headboard baffle 2 7 are both provided with a through slot 1 8, and the bed sheet 10 passes through the through slot 1 8 and extends to the top of the bed board 5. The two sides of the bed frame 4 are respectively provided with a guide roller 1110 and a guide roller 2 1111, and the guide roller 1110 and the guide roller 2 1111 are provided for guiding the bed sheet 10. Two limit bars 1120 are fixedly installed inside the through slot 2 1101, and the two limit bars 1120 are symmetrically installed on the upper and lower sides of the through slot 2 1101. A clamping ball head 1114 is provided inside the through slot 2 1101, and a clamping groove 1115 is provided on the outer surface of the clamping ball head 1114. The clamping ball head 1114 is movably clamped between the two limit strips 1120 through the clamping groove 1115, and the rotating shaft 1102 is fixedly installed inside the clamping ball head 1114. The width of the limit strip 1120 is smaller than the thickness of the through groove 1101, and one end of the through groove 1101 is arc-shaped. A fixing plate 1104 is fixedly installed on the surface of one side of the supporting box 1, and a motor 1105 is fixedly installed on the top surface of the fixing plate 1104. A pulley 1106 is fixedly installed on the output end of the motor 1105 and one end of the rotating shaft 1103, and a transmission belt 1107 is sleeved between the two pulleys 1106.

[0024] During operation, after a patient is transferred, the motor 1105 can be controlled to start. During the starting process of the motor 1105, the second shaft 1103 can be driven to rotate under the transmission action of the pulley 1106 and the transmission belt 1107. During the rotation of the second shaft 1103, the winding roller 1113 outside the second shaft 1103 can be driven to rotate to rewind the bed sheet 10. During the rewinding process, the first shaft 1102 is clamped between the two limit strips 1120 through the clamping groove 1115 provided on the outer surface of the clamping ball head 1114. Therefore, the clamping ball head 1114 will be driven to move between the two limit strips 1120 through the bed sheet 10. The new bed sheet 10 is moved to the arc position of the second through groove 1101, so that the new bed sheet 10 wrapped around the outside of the storage roller 1112 installed on the outer surface of the rotating shaft 1102 can be released. That is, when the clamping ball head 1114 reaches the arc position of the second through groove 1101, the rotating shaft 1102 can be rotated to release the new bed sheet 10. The new bed sheet 10 is guided by the guide roller 2 1111 and the guide roller 1 1110 and moves above the bed board 5 until the new bed sheet 10 completely covers the top of the bed board 5. The bed sheet can be quickly replaced, and the bed sheet 10 used by the previous patient will be rolled up on the outer surface of the winding roller 1113.

[0025] Through the above-mentioned arrangement, it is possible to roll up the used bed sheet 10 after the previous patient has used it, and to re-lay the new bed sheet 10 on the bed board 5 during the rolling process, thereby realizing the rapid replacement of the bed sheet 10 and avoiding the problem of slow and inefficient manual replacement of the bed sheet 10. The above-mentioned working process can be replaced during the overall movement of the device, that is, after the previous patient has used it, while pushing the device as a whole to transport the next patient, rapid automatic replacement can be achieved, further increasing the overall practicality of the device, and greatly saving time, so that more patients can be transported within a limited time.

[0026] Among them, after the replacement is completed, the locking ball head 1114 can return to between the two limit strips 1120 under the reaction force of the spring 2 18, and automatically tighten the bed sheet 10 laid on the bed board 5, so that the bed sheet 10 can be laid more flat, increasing the comfort of professional patients and also increasing the standardization of the appearance of the device.

[0027] A rectangular groove 1117 is provided above the through groove 1101, and a horizontal support plate 1119 is movably connected inside the rectangular groove 1117. A spring 1118 is fixedly connected between the bottom surface of the horizontal support plate 1119 and the top of one of the limit strips 1120. A partition frame 1116 is installed above the horizontal support plate 1119. The partition frame 1116 is movably connected to the inner wall of the support box 1, and the inner bottom surface of the partition frame 1116 is in contact with the outer surface of the winding roller 1113. An alarm is installed on the outside of the support box 1, and a touch switch 34 is fixedly installed in the middle of the top surface of the rectangular tube 27. The touch switch 34 is fixedly connected to the alarm outside the support box 1.

[0028] During operation, as more sheets 10 are rolled up outside the winding roller 1113, the diameter of the winding roller 1113 will continue to increase. Since the inner bottom surface of the partition frame 1116 is in contact with the outer surface of the winding roller 1113, that is, when the outer surface of the winding roller 1113 rolls up the sheets 10, the rolled sheets 10 are in contact with the inner bottom surface of the partition frame 1116. As more sheets 10 are rolled up by the winding roller 1113, the diameter will increase, which will push the partition frame 1116 to support the box. 1 moves downward, that is, drives the horizontal support plate 1119 to move inside the rectangular groove 1117, and the spring 1118 is in a taut state until the bottom surface of the partition frame 1116 is in contact with the touch switch 34, and then the touch switch 34 controls the alarm outside the support box 1 to sound an alarm to remind that the bed sheet 10 rolled up outside the winding roller 1113 has reached the limit, that is, the bed sheet 10 outside the storage roller 1112 has been used up and needs to be replaced in time.

[0029] By setting the partition frame 1116, the winding roller 1113 can be in a relatively sealed state inside the supporting box 1, and the storage roller 1112 and the winding roller 1113 can be isolated, so that the used sheets 10 rolled up on the outer surface of the winding roller 1113 will not affect the new sheets 10 on the outer surface of the storage roller 1112.

[0030] A disinfection assembly is arranged inside the support box 1, and the disinfection assembly includes a mounting frame 17, and two clamping blocks 19 are movably clamped inside the mounting frame 17, and a spring 2 18 is installed between the two clamping blocks 19, and a support 20 is fixedly installed on one side surface of the two clamping blocks 19, and a sleeve shaft 15 is rotatably sleeved on the outer surface of the rotating shaft 1102, and a C-shaped frame 16 is fixedly installed on the outer surface of the sleeve shaft 15, and a support 22 is fixedly installed on the outer surface of the C-shaped frame 16 located inside the support box 1, and an inclined plate 21 is installed between the support 22 and the support 1 20, and a rectangular tube 27 is fixedly installed on the top surface of the support 22, and a plurality of atomizing nozzles 28 are fixedly installed on one side surface of the rectangular tube 27, and the rectangular tube 27 is located on one side of the storage roller 1112, and one side surface of the mounting frame 17 A mounting box 23 is fixedly installed on the surface, a storage box 24 is arranged above the mounting box 23, two liquid inlet pipes 32 are fixedly connected between the storage box 24 and the mounting box 23, the outer surfaces of the two liquid inlet pipes 32 are fixedly connected with a one-way valve 23, two sealing clamping plates 29 are movably clamped inside the mounting box 23, the two sealing clamping plates 29 divide the interior of the mounting box 23 into two cavities 31, the two liquid inlet pipes 32 are connected with the two cavities 31 respectively, one side surface of the mounting box 23 is fixedly connected with two liquid outlet pipes 25, the outer surfaces of the two liquid outlet pipes 25 are fixedly installed with a one-way valve 26, one end of the two liquid outlet pipes 25 are respectively located at the two cavities 31, and the other end of the two liquid outlet pipes 25 is fixedly connected to one side surface of the rectangular tube 27.

[0031] During operation, when the bed sheet 10 is being rolled up, that is, when the bed sheet 10 is being replaced, the intermittent start-up of the clamping groove 1115 is controlled so that the clamping ball head 1114 can move back and forth between the two limit bars 1120. During the movement, the two clamping blocks 19 can be driven to move back and forth inside the mounting frame 17 under the action of the spring 2 18, thereby driving the two inclined plates 21 to change their angles, that is, driving the two connecting shafts 30 to move back and forth inside the mounting box 23, and then driving the two sealing clamping plates 29 to move back and forth inside the two cavities 31. When the two sealing clamping plates 29 move in opposite directions under the driving action of the connecting shaft 30, the inside of the storage box 24 can be filled with liquid. The disinfectant is sucked into the interior of the two cavities 31 through the liquid inlet pipe 32. Conversely, when the two sealing clamping plates 29 move in the same direction under the movement of the two connecting shafts 30, the disinfectant sucked into the interior of the cavity 31 can be squeezed into the interior of the liquid outlet pipe 25 and enter into the interior of the rectangular tube 27. Finally, it is atomized and sprayed toward the direction of the bed sheet 10 through multiple atomizing nozzles 28, thereby achieving the purpose of disinfecting the bed sheet 10 during the process of changing the bed sheet 10. In addition, since the support 22 is fixedly connected to the C-frame 16, the rectangular tube 27 can always be located on one side of the storage roller 1112 and the position is fixed, so that the disinfectant can be better scattered on the outer surface of the bed sheet 10, which can further improve the disinfection effect.

[0032] A heating and drying mechanism 12 is arranged inside the through slot 8 opened in the headboard baffle 6, and the heating and drying mechanism 12 includes a positioning shaft 1201. There are two positioning shafts 1201, and the two positioning shafts 1201 are rotatably installed inside the through slot 8. A heating and drying roller 1202 is fixedly connected between the two positioning shafts 1201. An electric heating column 1203 is installed inside the heating and drying roller 1202. A plurality of heat-conducting frames 1204 are fixedly installed on the outer surface of the electric heating column 1203. A heat-conducting sheet 1205 is fixedly installed on one side surface of the plurality of heat-conducting frames 1204. The outer surface of the heat-conducting sheet 1205 is in contact with the inner wall of the heating and drying roller 1202. The installation height of the heating and drying roller 1202 is lower than the setting height of the bed board 5.

[0033] During operation, during the process of replacing the bed sheet 10, that is, during the movement of the bed sheet 10, since the installation height of the heating and drying roller 1202 is lower than the setting height of the bed board 5, the heating and drying roller 1202 can be driven to rotate inside the through groove 8 under the action of the bed sheet 10. At this time, by controlling the electric heating column 1203 to be energized, the electric heating column 1203 can heat the heating and drying roller 1202 through the heat conducting frame 1204 and the heat conducting sheet 1205. When the bed sheet 10 passes through the heated heating and drying roller 1202, on the one hand, the residual disinfectant can be evaporated, so that the bed sheet 10 can be dried quickly, and when it is laid on the top of the bed board 5, it can have a certain temperature, so that the patient can be more comfortable. On the other hand, when the bed sheet 10 passes through the heated heating and drying roller 1202, the heating and drying roller 1202 can have a good ironing effect on the passing bed sheet 10, so that the bed sheet 10 will not be wrinkled after being laid, and thus it appears more flat.

[0034] An external shaft 35 is fixedly installed on the outer surface of the sleeve shaft 15, a rectangular plate 36 is fixedly installed on the outer surface of the supporting box body 1, a touch switch 37 is fixedly installed on one side surface of the rectangular plate 36, a supporting column 13 is provided on one side of the supporting box body 1, an ultraviolet disinfection lamp 14 is fixedly installed on the top of the supporting column 13, and the ultraviolet disinfection lamp 14 is electrically connected to the rectangular plate 36.

[0035] During operation, through the set external shaft 35, when the clamping ball head 1114 moves, it can synchronously drive the external shaft 35 to move. When one end of the external shaft 35 contacts the rectangular plate 36, the ultraviolet disinfection lamp 14 can be started, and the bed sheet 10 is irradiated by the ultraviolet disinfection lamp 14, thereby achieving further disinfection and sterilization of the bed sheet 10.

[0036] Specifically, the working process or working principle of the patient transfer device for critical care clinical use is as follows: when in use, the patient to be transferred is placed on the upper part of the bed board 5, and then the lock of the self-locking universal wheel 3 is unlocked, and then the entire device can be moved by pushing the device to achieve the transfer of the patient. After arriving at the destination ward, it is only necessary to re-lock the self-locking universal wheel 3, and then transfer the patient to the bed in the ward. It is convenient, fast, simple and practical. The motor 1105 is controlled to start. During the start-up process of the motor 1105, the shaft 1103 can be driven to rotate under the transmission action of the pulley 1106 and the transmission belt 1107. During the rotation of the shaft 1103, the winding roller 1113 outside the shaft 1103 can be driven to rotate to wind up the bed sheet 10. During the winding process, the bed sheet 10 is wound up. During the process, since the rotating shaft 1102 is clamped between the two limit strips 1120 through the clamping groove 1115 opened on the outer surface of the clamping ball head 1114, the clamping ball head 1114 will be driven by the bed sheet 10 to move between the two limit strips 1120 until it moves to the arc position of the through groove 1101, so that the new bed sheet 10 wrapped outside the storage roller 1112 installed on the outer surface of the rotating shaft 1102 can be released, that is, when the clamping ball head 1114 reaches the arc position of the through groove 1101, the rotating shaft 1102 can be rotated to release the new bed sheet 10, and the new bed sheet 10 is guided by the guide roller 1111 and the guide roller 1110, and moves above the bed board 5 until the new bed sheet 10 completely covers the top of the bed board 5, so that the bed sheet can be quickly replaced; During the process of rolling up the bed sheet 10, that is, during the process of replacing the bed sheet 10, by controlling the intermittent start of the clamping groove 1115, the clamping ball head 1114 can move back and forth between the two limit bars 1120. During the movement, the two clamping blocks 19 can be driven to move back and forth inside the mounting frame 17 under the action of the spring 18, thereby driving the two inclined plates 21 to change their angles, that is, driving the two connecting shafts 30 to move back and forth inside the mounting box 23, and then driving the two sealing clamping plates 29 to move back and forth inside the two cavities 31. When the two sealing clamping plates 29 move in opposite directions under the driving action of the connecting shaft 30, the disinfectant inside the storage box 24 can be sucked into the interior of the two cavities 31 through the liquid inlet pipe 32. Conversely, when the two sealing clamping plates 29 move in the same direction under the movement of the two connecting shafts 30, the disinfectant sucked into the interior of the cavity 31 can be squeezed into the interior of the liquid outlet pipe 25 and enter into the interior of the rectangular tube 27, and finally atomized and sprayed toward the direction of the bed sheet 10 through the multiple atomizing nozzles 28, thereby achieving the purpose of disinfecting the bed sheet 10 during the process of changing the bed sheet 10.

[0037] It should be noted that the motor 1105 and the ultraviolet disinfection lamp 14 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
