Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent bed head angle control and alarm system. Background Art

[0002] For critically ill patients, raising the head of the bed by 30° to 45° is of great significance in the absence of contraindications. Raising the head of the bed by 30° to 45° can lower the patient's diaphragm, which is beneficial to the breathing of bedridden patients. For patients with enteral nutrition, it can reduce food reflux and prevent aspiration. For patients with endotracheal intubation and mechanical ventilation, raising the head of the bed below 30° is an independent risk factor for ventilator-associated pneumonia (VAP). Therefore, the Centers for Disease Control (CDC) in the United States stipulates that in order to prevent VAP, the patient's head of the bed should be raised by 30° to 45°. In addition, raising the head of the bed is conducive to abdominal drainage, localizing the infection, reducing the tension of the abdominal wound, and relieving pain.

[0003] However, the implementation rate of head-of-bed elevation in actual clinical work is not high. The main reason is that many beds currently do not have head-of-bed elevation angle devices. Even if there are head-of-bed elevation angle devices, sometimes the head of the bed is not elevated to the required level due to busy work or other factors. Currently, there is no head-of-bed elevation monitoring and alarm system in the clinic, which cannot monitor the implementation of head-of-bed elevation for critically ill patients in the ward, and cannot remind the nurses on duty that the head of the bed has not been elevated to the required level.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an intelligent bed head angle control and alarm system is provided, in order to achieve a more practical purpose. Summary of the invention

[0033] Cylinders 14 are fixedly installed at both ends of the movable rod 13, and the threaded rod 9 is threadedly sleeved with the movable rod 13; a slide groove 17 is opened on the inner side of the bed frame 1, and a slider 16 is slidably installed on the inner side of the slide groove 17, and the slider 16 is fixedly installed on the cylinder 14; a gear 15 is rotatably installed on the outer side of the cylinder 14, and a rack plate 10 is fixedly installed on the inner side of the bed frame 1, and the gear 15 and the rack plate 10 are adapted to mesh with each other.

[0034] In this embodiment, by providing a cylinder 14, a gear 15, and a slider 16, the movable rod 13 can move along the rack plate 10 through the gear 15 during movement, and cooperate with the slider 16 to slide along the slide groove 17, so that the movable rod 13 can smoothly drive the support rod 11 to adjust the tilt angle of the movable bed board 3, thereby ensuring the comfort of seriously ill patients during the process of raising the head of the bed.

[0037] A fixed block 7 is fixedly installed at the bottom of the fixed bed board 2. The fixed block 7 is rotatably sleeved with a rotating rod 8. One end of a threaded rod 9 is rotatably installed with the bed frame 1.

[0038] In this embodiment, by providing the fixing block 7 , the rotation of the rotating rod 8 can be restricted, thereby ensuring the stable rotation of the rotating rod 8 .

[0039] An intelligent hospital bed alarm system includes, for example, an intelligent hospital bed head angle control system, wherein a battery 601, a signal generator 602, and a gyroscope angle sensor 608 are fixedly installed on the inner side of an angle measuring device 6, and the battery 601 is electrically connected to the signal generator 602; a measuring angle plate 607 is provided on one side of the angle measuring device 6, and a conductive track 603 is fixedly installed on one side of the measuring angle plate 607, and an insulating member 604 is movably sleeved on the outer side of the conductive track 603, and the insulating member 604 is in frictional contact with the conductive track 603; a pointer 605 is rotatably installed on one side of the measuring angle plate 607, and a gravity block 606 is fixedly installed on the bottom end of the pointer 605, and the top end of the pointer 605 is in sliding contact with the conductive track 603, the battery 601 is electrically connected to the measuring angle plate 607, and the signal generator 602 is electrically connected to the measuring angle plate 607.

[0040] In this embodiment, by providing a battery 601, a signal generator 602, and a measuring angle plate 607, when a preset lifting angle is required, the insulating member 604 is moved along the conductive track 603, and the insulating member 604 is adjusted to the corresponding scale position of the measuring angle plate 607 according to the lifting angle requirement of the movable bed board 3. As the head of the bed is lifted, the pointer 605 is powered off when it reaches the preset angle, otherwise it is not within the preset angle, the entire circuit is powered on, the signal generator 602 works, and the central monitoring station receives the signal and generates an audible and visual alarm to remind the staff that the head of the bed cannot be lifted, so that the lifting execution of the movable bed board 3 of critically ill patients in the ward can be monitored in real time, and an alarm can be issued for the execution that is not in place, so that the medical staff can lift the corresponding bed. The model of the gyroscope angle sensor 608 is WT9011DCL-BT50, and the gyroscope angle sensor 608 can synchronize the improved angle data to the computer in real time and save the data.

[0041] Among them, Figure 7 As shown, part A: angle measurement and signal generating device, mainly including battery 601, angle measuring device 607, signal generating device 602; part B: signal receiving and alarm device, mainly including signal receiver and sound and light alarm of each bed unit.

[0042] Working principle: When in use, the medical staff first needs to preset the elevation angle, and then move the insulating member 604 along the conductive track 603, and adjust the insulating member 604 to the corresponding scale position of the measuring angle plate 607 according to the lifting angle required for the movable bed board 3;

[0043] When adjusting the tilt position of the movable bed board 3, the medical staff drives the rotating rod 8 and the threaded rod 9 to rotate by rotating the turntable 5, so that the threaded rod 9 drives the movable rod 13 to make the support rod 11 drive the movable bed board 3 to rotate, tilt and lift. During the movement, the movable rod 13 moves along the rack plate 10 through the gear 15, and the cylinder 14 drives the slider 16 to slide along the slide groove 17. The movable rod 13 can smoothly drive the support rod 11 to adjust the tilt angle of the movable bed board 3 and lift the movable bed board 3 to the required position;

[0044] At this time, as the head of the bed is raised, the pointer 605 is powered off when it reaches the preset angle. Otherwise, if it is not within the preset angle, the entire circuit is powered on, the signal generator 602 works, and the central monitoring station receives the signal and generates an audible and visual alarm to remind the staff that the head of the bed cannot be raised. This allows real-time monitoring of the lifting of the movable bed board 3 for critically ill patients in the ward, and an alarm can be issued for any failure to perform the lifting operation, making it easier for medical staff to lift the corresponding bed.
