[0030] It should be noted that: when the patient gets out of bed alone, the blocking alarm mechanism can cause the movable plate 9 to open and call the receiving bracelet to issue an alarm to notify family members.

[0031] It should be noted that the mattress is equipped with an alarm, which is placed at the medical staff's place.

[0032] The blocking alarm mechanism includes a driving support box 6, a driving component arranged on the inner side of the driving support box 6 and a fixed sleeve 5 connected to the driving component, the fixed sleeve 5 is slidably connected with a blocking plate 4 inside, the driving component includes a bidirectional cylinder 11 installed inside the driving support box 6, the output ends of both ends of the bidirectional cylinder 11 are fixedly connected with a guide plate 14, the side wall of the guide plate 14 is fixedly connected with a movable plate 9, and one end of the movable plate 9 is fixedly connected to the fixed sleeve 5.

[0033] It should be noted that: under the control of the controller, the bidirectional cylinder 11 can push the movable plates 9 on both sides to move, so that the movable plates 9 move out of the driving support box 6, thereby widening the bed and pneumatically preventing the patient from getting out of bed alone.

[0034] The inside of the induction tube 8 is slidably connected with a pneumatic shaft 803, the surface of the pneumatic shaft 803 is provided with a groove, and a dynamic photoelectric sensor 802 is installed in the groove. The surface of the induction tube 8 is provided with a mounting tube connected to it, and a static photoelectric sensor 801 is installed inside the mounting tube.

[0035] It should be noted that: when the patient gets out of bed, he needs to stand up first and then lift his legs to get out of bed. When the patient stands up and then lifts his legs, the airbag layers on both sides are free of pressure and reset, and the pneumatic shaft 803 at the corresponding position resets. At this time, the static opposing photoelectric sensor 801 and the dynamic opposing photoelectric sensor 802 are aligned with each other (only when the static opposing photoelectric sensors 801 and the dynamic opposing photoelectric sensors 802 on both sides are aligned with each other will they feedback signals to the controller), and feedback signals to the controller, and the controller controls the two-way cylinder 11 to work, and the two-way cylinder 11 pushes the movable plates 9 on both sides to move, so that the movable plates 9 move out of the driving support box 6, thereby widening the bed and preventing the patient from getting out of bed alone;

[0036] At the same time, the controller controls the alarm of the medical staff and the call receiving bracelet in the hands of the family members to sound an alarm, so that the family members and medical staff can reach the patient in time to prevent the patient from falling.

[0038] A connecting pipe is fixedly connected between the fixed sleeves 5, an air pump 10 is installed inside the driving support box 6, the air outlet end of the air pump 10 is fixedly connected to a three-way air pipe 7, the other two ends of the three-way air pipe 7 are fixedly connected to an air pumping pipe through a telescopic hose, the air pumping pipe is fixedly connected to the fixed sleeve 5, an electromagnetic valve is arranged on the air pumping pipe, and a controller and a balance sensor are arranged at the bottom end of the L-shaped bottom plate 2.

[0039] It should be noted that: when the patient rolls over at night and rolls to the side of the hollow mattress 1, the patient's own gravity will cause that side of the hollow mattress 1 to tilt slightly (the sliding support plate 12 will press down the support spring 15). At this time, the balance sensor will sense the tilt of the hollow mattress 1 and feedback a signal to the controller. The controller controls the air pump 10 to work and open the solenoid valve on the air pump pipe on the tilted side at the same time. The air pump 10 pumps air to the inside of the fixed sleeve 5 through the three-way air pipe 7, so that the blocking plate 4 rises, thereby preventing the patient from rolling off the bed.

[0040] It is worth noting that a pressure relief valve for deflation is provided on the fixed sleeve 5 , and medical staff or family members need to manually open the pressure relief valve to deflate the fixed sleeve 5 , so that the blocking plate 4 moves back to its original position under the action of its own gravity.

[0041] A movable groove is provided on the side wall of the L-shaped bottom plate 2, a mounting block is slidably connected in the movable groove, and an infrared blood oxygen probe 3 is mounted on the mounting block.

[0042] It should be noted that when it is necessary to detect the patient's vital signs (blood oxygen saturation, mean arterial pressure, pulse rate, etc.), the infrared blood oxygen probe 3 can be turned on and slid to face the patient.

[0043] When the present invention is in use, when a patient gets out of bed alone, the patient will first stand up and then lift his legs to get out of bed. At this time, the airbag cushions 101 on both sides are free of pressure and reset, and the pneumatic shafts 803 at the corresponding positions are reset. At this time, the dynamic photoelectric sensor 802 and the static photoelectric sensor 801 are aligned with each other and feedback signals to the controller. The controller controls the two-way cylinder 11 to work, and the two-way cylinder 11 pushes the moving plates 9 on both sides to move, so that the moving plates 9 move out of the driving support box 6, which can realize the function of widening the bed and prevent the patient from getting out of bed alone. At the same time, the controller controls the alarm in the hands of the medical staff and the call receiving bracelet in the hands of the patient's family members to send out an alarm sound, so that the medical staff or family members can reach the patient in time to prevent the patient from continuing to get out of bed, thereby preventing the patient from falling when getting out of bed alone.

[0044] When the patient rolls over at night and approaches the bedside, the patient's own gravity will press down one side of the hollow mattress 1, causing one side of the hollow mattress 1 to tilt slightly. At this time, the balance sensor will sense the tilt of the hollow mattress 1 and feedback to the controller. The controller controls the air pump 10 to work and opens the solenoid valve on the air pump pipe on the tilted side. The air pump 10 pumps air to the inside of the fixed sleeve plate 5 through the three-way air pipe 7, so that the blocking plate 4 rises, thereby preventing the patient from rolling off the bed.

[0045] When it is necessary to monitor the patient's vital signs, the infrared blood oxygen probe 3 can be slid to face the patient. After the detection is completed, it can be slid to one side so that the patient can lean against the L-shaped bottom plate 2.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
