They need caregivers to help them turn over and move, etc. They also need to be moved to the examination department from time to time for corresponding examinations. The whole process is quite laborious. For this reason, various turning devices that can assist in turning over to prevent pressure sores or turning beds integrated with the bed have come into being. There are also various devices for conveniently moving patients from bed to bed. Some bed-changing devices also have the function of assisting turning over. For example, the Chinese utility model patent application with application number CN202121484298.X provides a device for assisting patients in turning over and changing beds. In this way, turning over and changing beds are integrated into one, which is convenient for operation. However, the device is not convenient for patients who are not lying on the device to change beds, because during the examination process, the patient will be transferred from the hospital bed to the transfer bed, and then from the transfer bed to the examination bed. After the examination, it is necessary to transfer from the examination bed to the transfer bed and then to the hospital bed. The whole process involves multiple bed changes, and sometimes it is also necessary to turn over and lie on the side during the examination. Therefore, in addition to the convenience of changing beds when lying on the device, additional bed boards are required for changing beds at other times, and there is still a certain inconvenience in use.

[0029] The utility model realizes the movement of the entire device through the setting of the pulley assembly, so as to facilitate the patient to pass the bed. Among them, the auxiliary wheel 2 of the pulley assembly is movably installed on the base plate 1, and it can extend out of the first accommodating groove 1.1 under the action of the driving rod 5 abutting the wheel frame 3, thereby replacing the bottom of the base plate 1 as a support, so that the bottom can be rolled and moved, which is convenient for medical staff to push the device to move, saving time and effort to a certain extent. When the driving rod 5 does not abut the wheel frame 3, the bottom of the auxiliary wheel 2 is stressed, and the base plate 1 has a downward pressure. The auxiliary wheel 2 retracts into the first accommodating groove 1.1 without the downward force of the driving rod 5. At this time, the bottom of the base plate 1 is supported as a supporting part, the base plate 1 is not easy to slide, and the device can be stably placed on the bed surface.

[0030] In this embodiment, in order to prevent the auxiliary wheel 2 from falling off the base plate 1, a limiting plate 4 is preferably provided at the end of the wheel frame 3 located in the second accommodating groove 1.2 to prevent the end of the wheel frame 3 located in the second accommodating groove 1.2 from sliding into the first accommodating groove 1.1. The limiting plate 4 is accommodated in the second accommodating groove 1.2 and restricted in the second accommodating groove 1.2. It can move in the second accommodating groove 1.2. The driving rod 5 pushes the wheel frame 3 to drive the auxiliary wheel 2 to slide downward by abutting against the limiting plate 4, thereby causing the auxiliary wheel 2 to extend out of the first accommodating groove 1.1.

[0031] Further, the driving rod 5 is detachably connected to the second accommodating groove 1.2, that is, the driving rod 5 can be removed from the second accommodating groove 1.2, so that the driving rod 5 is prevented from protruding from the bottom plate 1 when not in use, thereby posing a safety hazard to the patient. Preferably, a storage hole 1.3 is provided on the side wall of the bottom plate 1, and the driving rod 5 is detachably connected to the storage hole 1.3, and the driving rod 5 is stored through the storage hole 1.3 when not in use to prevent loss. More preferably, the storage hole 1.3 is a threaded hole, and the driving rod 5 is threadedly connected to the storage hole 1.3, and one driving rod 5 matches one storage hole 1.3 to improve the stability of the driving rod 5 placed on the storage hole 1.3; in addition, in order to facilitate the operation of patients and medical staff, it is preferred that the storage hole 1.3 is set on the side walls at both ends in the length direction of the bottom plate 1, so that the driving rod 5 can be hidden without affecting others by being stored sideways. More preferably, the end of the driving rod 5 located above the base plate 1 is provided with an annular operating handle 6, and the annular operating handle 6 facilitates the operation of the driving rod 5. At the same time, when the driving rod 5 is installed in the second receiving groove 1.2, it can also be used as a pull handle or a push handle, which is convenient for medical staff to push the device to move. When the driving rod 5 is installed in the storage hole 1.3, it can be used as a connecting ring. In addition, with the structure of the auxiliary fixing belt, the base plate 1 can be connected to the bed body, thereby improving the stability of the device placed on the bed body. Therefore, preferably, the integrated device for assisting patients to turn over and pass the bed also includes a fixing rope for fixing the base plate 1 to the bed, and one end of the fixing rope is connected to the annular operating handle 6.

[0032] In addition to the effect of convenient bed movement brought by the pulley assembly, the utility model can also have a turning effect brought by a turning mechanism to prevent bedsores. There are many kinds of turning mechanisms, and this embodiment provides one of them. Specifically, the turning mechanism includes two turning airbags 7, an air source device and a controller. The two turning airbags 7 are arranged in the middle of the bed board and are arranged at intervals along the width direction of the base plate 1. Each turning airbag 7 is connected to the air source device through an air pipe 8. The air source device is arranged outside the base plate 1 and connected to the controller. The air source device operates under the action of the controller to control the inflation and deflation of the turning airbag 7. Preferably, the air source device is detachably connected to the air pipe 8. The controller is installed on the air source device, which is connected to the power supply device. In addition, the controller is also connected to the operating screen. The operating screen and the controller are integrated in a control box. The controller has a timing function to achieve the purpose of timing to drive the air source device to operate, thereby achieving the purpose of timing turning.

[0033] Through the above-mentioned arrangement, the integrated device of the utility model can assist the patient to turn over, and can facilitate the patient to change beds when it is necessary. The bed-changing is to move the patient together with the integrated device. After the integrated device completes the bed-changing, it is not detached. The purpose of this arrangement is to facilitate the patient to change beds multiple times. For example, after changing from an inpatient bed to a transfer bed, the patient is transferred to the examination room to be examined with the transfer bed, and then changes from the transfer bed to the examination bed. After the examination on the examination bed is completed, the patient changes to the transfer bed, and then returns to the hospital bed. In this case, the overall migration of the device is better for use, and if the examination requires lying on the side, the device can also assist in turning over and lying on the side, thereby improving the efficiency of the examination.

[0034] In the second embodiment of the present invention, please refer to Figure 7 The bottom plate 1 is divided into two sub-plates 9, and the two sub-plates 9 are arranged side by side along the width direction of the bottom plate 1 to form a bottom plate 1. Each sub-plate 9 is provided with a pulley assembly and a turning airbag 7 structure. The two sub-plates 9 are detachably connected, and a connecting and fixing block 10 is detachably provided at the connection, such as a detachable connection method such as a card block card hole, an additional threaded rod plug-in, etc. The connecting and fixing block 10 simultaneously connects the two sub-plates 9, which are arranged at both ends of the length direction of the sub-plate 9, so that the bottom plate 1 can be detached from the patient by dividing the bottom plate 1 into two and setting the connecting and fixing block 10. That is to say, when the utility model needs to be removed, the patient can be placed on his side by the turning mechanism, and the connecting and fixing block 10 can be detached from the dividing plate 9, and the two dividing plates 9 are not connected. Then, the dividing plate 9 that is not pressed on the patient's side can be removed, and the patient can be placed flat and then the other dividing plate 9 can be pulled out. Alternatively, the turning mechanism can be used to turn the patient to lie on his side in the opposite direction, and the other half of the patient's body can be lifted up. The patient who is lying on his side again can be supported, and the turning mechanism can be reset. Most of the dividing plate 9 is exposed, and at this time, the dividing plate 9 can be taken out. This method is convenient for taking out the bottom plate 1 from under the patient, which saves time and effort and is easy to operate.
