Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of monitoring bed, especially a bedside angle automatic adjustment monitoring bed based on infrared induction. BACKGROUND
[0002] Bed head lifting 30 degrees has multiple benefits in medical care, especially in intensive care unit (ICU), this body position adjustment is crucial to the recovery of patients. Bed head lifting 30 degrees can improve breathing difficulties, prevent ventilator-associated pneumonia (VAP), reduce abdominal wound tension, promote digestion and reduce intracranial pressure, etc. In addition, this body position adjustment is also beneficial to abdominal cavity drainage, limiting infection and reducing abdominal wound tension, thereby reducing pain and promoting wound healing.
[0003] In actual clinical work, medical staff need to regularly check patients, and need to adjust the monitoring bed to be flat or to be higher in angle. After the examination is completed, the bed needs to be adjusted back to 30 degrees. However, due to the busy work of medical staff, some medical staff may forget to adjust the bed back to 30 degrees after detecting the patient. In addition, the bed is manually adjusted in angle, and medical staff cannot accurately adjust the angle to the standard 30 degrees, which may cause some errors and affect the recovery of patients. UTILITARY MODEL
[0004] In order to solve the above problems, the utility model provides a bedside angle automatic adjustment monitoring bed based on infrared induction, which can automatically adjust the monitoring bed back to 30 degrees and assist patients in better recovery.
[0005] Therefore, the technical scheme of the utility model is: a bedside angle automatic adjustment monitoring bed based on infrared induction, comprising a bed frame, a first bed plate and a second bed plate are arranged on the bed frame, a hydraulic rod is arranged below the first bed plate; further comprising a control module and an operation panel, a key is arranged on the operation panel, the control module controls the work of the hydraulic rod through the key instruction; a group of infrared induction components are arranged on each side of the bed frame, the infrared induction components send an induction signal to the control module, the control module controls the work of the hydraulic rod according to the induction signal to adjust the inclination angle of the first bed plate; a height sensor is arranged on the bed frame to detect the height of the first bed plate.
[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the infrared induction component comprises an infrared transmitting end and an infrared receiving end, and the infrared induction component is used for detecting the personnel staying condition on both sides of the bed frame.
[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the control module comprises an infrared signal receiving unit, a timing unit, a height detection unit, a storage unit and a hydraulic rod control unit.
[0008] The infrared signal receiving unit is used to receive the sensing signals sent by the two sets of infrared sensing components. The timing unit is used to record the duration of continuous reception of sensing signals by the infrared signal receiving unit and compare it with a preset time threshold. The hydraulic rod control unit is used to drive the hydraulic rod to rise and fall, and adjust the tilt angle of the first bed board. The height detection unit is used to acquire the signal from the height sensor and acquire the height value of the first bed board in real time. The storage unit is used to store the height setting values corresponding to different tilt angles of the first bed board.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the storage unit stores the height setting value corresponding to the 30-degree tilt angle of the first bed board.
[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the control module further includes a key instruction receiving unit, which is used to receive instruction signals from the keys on the operation panel, and drive the hydraulic rod to rise and fall through the hydraulic rod control unit to adjust the tilt angle of the first bed board.
[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the first bed board is rotatably mounted on the bed frame via a rotating shaft, the bottom of the hydraulic rod is rotatably mounted on the bed frame, and the output end of the hydraulic rod is rotatably connected to the bottom of the first bed board.
[0012] Infrared sensing components are installed on both sides of the monitoring bed. When medical staff are on either side of the monitoring bed, they will block the signal transmission between the infrared transmitter and receiver on that side. As long as the signal transmission of the infrared sensing component on one side is interrupted, the medical staff can operate normally, adjusting the status of the monitoring bed and performing corresponding examinations on the patient via buttons on the control panel. When the medical staff leaves, the signal transmission between the infrared transmitter and receiver on both sides of the monitoring bed is normal. After the signal continues for a certain period of time, it can be determined that the medical staff has completed the examination and left the detection range of the monitoring bed. At this time, the height detection unit can detect the height of the first bed board and compare it with the height setting value corresponding to the 30-degree tilt angle of the first bed board stored in the storage unit. It can be determined whether the tilt angle of the first bed board is 30 degrees. If it is not 30 degrees, the hydraulic rod control unit is used to drive the hydraulic rod to raise or lower, adjusting the tilt angle of the first bed board, raising or lowering the first bed board until the real-time height value measured by the height sensor is consistent with the height setting value corresponding to the 30-degree tilt angle. Then the hydraulic rod stops working, and the first bed board is maintained at a 30-degree tilt angle.
[0013] Compared with the prior art, the beneficial effects of this utility model are: infrared sensing components for detecting medical staff are set on both sides of the electrically adjustable monitoring bed. When the medical staff are not detected at the bedside, the control module can drive the hydraulic rod to lift and lower, automatically adjusting the tilt angle of the monitoring bed to 30 degrees. This avoids the problem of the monitoring bed not being in the correct position due to the negligence of medical staff, reduces the workload of medical staff, and helps patients recover better.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.
[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.
[0020] See the attached figures. The infrared-sensing-based automatic headboard angle adjusting monitoring bed described in this embodiment includes a bed frame 1, on which a first bed board 2 and a second bed board 3 are mounted. Reversible guardrails 4 are provided on both sides of the first bed board 2 and the second bed board 3. The first bed board 2 is rotatably mounted on the bed frame 1 via a pivot 5. A hydraulic rod 6 is located below the first bed board 2. The bottom of the hydraulic rod 6 is rotatably mounted on the bed frame 1, and the output end of the hydraulic rod 6 is rotatably connected to the bottom of the first bed board 2. The hydraulic rod 6 is a double-acting hydraulic rod; by hydraulically controlling the extension height of the hydraulic rod, the tilt angle of the first bed board 2 can be adjusted to meet the different usage needs of patients.
[0021] The monitoring bed 1 is also equipped with an operation panel 7, which can be fixed to the bed frame or be a remote control. The operation panel has buttons, including function buttons for raising, lowering, slowing down, and speeding up. The monitoring bed has a control module inside, which includes a button command receiving unit for receiving command signals from the buttons on the operation panel. The control module drives the hydraulic rod to raise and lower via the hydraulic rod control unit, thereby adjusting the tilt angle of the first bed board. Using the buttons on the operation panel 7 to adjust the tilt angle of the first bed board is a mature existing technology, and the corresponding electrical control principles are common knowledge and will not be elaborated here.
[0022] The technology of this embodiment is as follows: the existing electric monitoring bed is equipped with an automatic 30-degree reset function. Therefore, in this embodiment, an infrared sensing component 8 is provided on each side of the bed frame 1. The infrared sensing component 8 includes an infrared transmitter 81 and an infrared receiver 82. When medical staff stand on either side of the monitoring bed, the signal transmission between the infrared transmitter 81 and the infrared receiver 82 on that side will be blocked. The infrared sensing component 8 can be used to detect whether there are people staying on both sides of the bed frame.
[0023] Meanwhile, a height sensor 9 is installed on the bed frame 1. The height sensor 9 typically uses laser or ultrasonic technology for measurement and can detect the lifting height of the first bed board 2. The height values corresponding to different lifting angles of the first bed board 2 can be calculated, including the height set value corresponding to a 30-degree tilt angle of the first bed board.
[0024] The control module includes an infrared signal receiving unit, a timing unit, a height detection unit, a storage unit, and a hydraulic rod control unit. The infrared signal receiving unit receives sensing signals from two sets of infrared sensing components. When medical staff stand on either side of the bed frame, the infrared signal receiving unit will not receive the sensing signal from the infrared sensing component on that side, meaning the infrared signal receiving unit only receives one set of sensing signals. At this time, the monitoring bed is in the manual operation stage, and medical staff can adjust the status of the monitoring bed and perform operations such as examinations on the patient through the operation panel. When the medical staff leaves the bedside, the infrared signal receiving unit will continuously receive sensing signals from both sets of infrared sensing components.
[0025] The timing unit can record the duration of two sets of sensing signals continuously received by the infrared signal receiving unit and compare them with a preset time threshold. For example, if the preset time threshold is set to 1 minute, when the infrared signal receiving unit receives two sets of sensing signals for 1 minute, it means that the medical staff on either side of the bed frame has indeed left. At this time, the height detection unit can detect the height of the first bed board and compare it with the height setting value corresponding to the 30-degree tilt angle of the first bed board stored in the storage unit to determine whether the tilt angle of the first bed board is 30 degrees. If it is not 30 degrees, the hydraulic rod control unit is used to drive the hydraulic rod to raise and lower, adjust the tilt angle of the first bed board, so that the first bed board reaches a 30-degree tilt angle.
[0026] When in use, if medical staff are positioned on either side of the monitoring bed, the signal transmission between the infrared transmitter and receiver on that side will be blocked. At this time, medical staff can still operate the monitoring bed normally, adjusting its status and performing relevant examinations on the patient via buttons on the control panel.
[0027] When the medical staff leaves, the signal transmission between the infrared transmitter and receiver on that side resumes. The signal continues for one minute (received intermittently, possibly while the medical staff is still moving around), indicating that the medical staff has completed the examination and left. At this point, the height detection unit detects the current height of the first bed board and compares it with the height setting value corresponding to a 30-degree tilt angle stored in the storage unit. It determines whether the tilt angle of the first bed board is 30 degrees. If it is not 30 degrees, the hydraulic rod control unit drives the hydraulic rod to raise or lower, adjusting the tilt angle of the first bed board, until the real-time height value measured by the height sensor matches the height setting value corresponding to a 30-degree tilt angle. Then, the hydraulic rod stops working, and the first bed board remains at a 30-degree tilt angle.
[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
