[0036] In this embodiment, in order to ensure the stable connection of the wheelchair mechanism and the bed frame 1, when the wheelchair mechanism is in the Figure 5 position, the medical staff pushes the push plate 23 to move, the push plate 23 drives the sleeve 27, the annular block 28 and the wedge-shaped block 34 to move, the wedge-shaped block 34 moves to abut against the spherical surface of the second hemispherical block 32, under the limiting of the pressure, the wedge-shaped block 34 extrudes the second springs 35 and slides into the sliding groove 33, in this way, the first hemispherical block can be extended into the sleeve 27, then the push plate 23 is no longer limited, the push plate 23 is reset under the action of the first springs 26, at this time, the wedge-shaped block 34 abuts against the second hemispherical block 32, as shown in Figure 6 , in this way, the wheelchair mechanism and the bed frame 1 can be stably locked together;

[0037] If the wheelchair mechanism needs to be moved, the medical staff moves the plate 23 to drive the sleeve 27, the annular block 28 and the wedge block 34 to move, the wedge block 34 moves and abuts against the first hemispherical block 31, under the limiting pressure, the wedge block 34 extrudes the second spring 35 and slides into the sliding groove 33, then the plate 23 is no longer limited, the plate 23 is reset under the action of the first spring 26, the wedge block 34 extrudes the second spring 35 and slides into the sliding groove 33 under the abutting of the first hemispherical block 31 and the spherical surface of the second hemispherical block 32, and finally the first hemispherical block 31 is separated from the sleeve 27, so that the wheelchair mechanism can be moved away.

[0038] Embodiment 3

[0039] With reference to Figure 7 The difference between the embodiment and the embodiments 1 and 2 is that the embodiment further comprises a monitoring mechanism for monitoring, the monitoring mechanism comprises a camera 41 and a control box 42, a U-shaped block 36 is installed on the bed frame 1, a clamping block 37 is slidably connected in the U-shaped block 36, a clamping screw 38 is rotatably connected to the bottom of the clamping block 37, the clamping screw 38 penetrates through the bottom of the U-shaped block 36 and is threadedly connected therewith, a hand wheel 39 is fixedly connected to the bottom of the clamping screw 38, the control box 42 is installed at the upper end of the U-shaped block 36, a shaped hose 40 is fixedly connected to the upper end of the U-shaped block 36, and the camera 41 is connected to the other end of the shaped hose 40.

[0041] The application further discloses a nursing bed monitoring system capable of monitoring the state of a body, comprising a control box 42 and a camera 41, wherein the control box 42 is internally provided with a control center, a camera module, a storage module, a call recognition module, a call module, a recognition module, an encryption module, a sensing module and an alarm module, the camera module, the storage module, the call recognition module, the call module, the recognition module, the encryption module, the sensing module and the alarm module are connected with the control center, the camera module is connected with a temperature sensor, the camera module is connected with the camera 41, the temperature sensor is installed on the camera 41, and the sensing module is connected with a heartbeat sensing sensor.

[0042] When using the system, the patient's family members need to encrypt the images collected by the camera 41 through the encryption module, that is, set a password for them. Only the patient's family members can know the video collected by the camera 41 through the password. Specifically:

[0043] The state of the patient can be known through the camera 41, and the body temperature of the patient can be monitored through the temperature sensor. The camera 41 can also know the state of the patient treated by the medical staff and the medicine used. The video information is transmitted to the camera module, and the camera module transmits the information to the control center and is encrypted by the password set by the patient's family members and stored in the storage module.

[0044] The heartbeat sensing module can be worn on the patient's head, and the patient's heart rate can be known in real time. The information of the heart rate is transmitted to the control center by the sensing module and stored in the storage module after encryption.

[0045] When the patient feels unwell, the patient can reciprocally shake the head to move the heartbeat sensing module. The camera 41 transmits the collected information to the control center, and the control center transmits the information to the identification module for identification. The information is compared with the unwell calling action for communication with the patient. If it is consistent with the unwell calling action for communication with the patient, the information is transmitted to the control center, which is encrypted and stored in the storage module. Then the information is transmitted to the calling module and the alarm module. The calling module calls the fixed telephone of the on-duty personnel, and the alarm module calls the medical staff to facilitate better rescue of the patient.

[0046] The video is set to be encrypted and only the patient's family members can open the video. In this way, the care of the patient by the medical staff, the medication and the real-time state of the patient can be known to prevent serious consequences caused by the patient's discomfort, and the family members cannot know. It can also prevent the medical staff from deleting the video arbitrarily and avoid medical harassment.

[0047] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
