Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an instrument for accurately measuring the elevation angle of a medical bed head. Background Art

[0002] At present, the hospital beds used in clinical practice can all adjust the head elevation angle of the bed through the rocker at the end of the bed to adjust the patient's body position. While meeting the patient's comfort, it can also meet the requirements of different head elevation angles for different diseases. For example, the head and chest are elevated by 10°-20° in the concave lying position, the head of the bed is elevated by 30°-50° in the semi-sitting position, the head of the bed is elevated by 70°-80° in the sitting position, and the head of the bed is elevated by 30°-50° in critically ill patients without contraindications to reduce the incidence of ventilator-associated pneumonia.

[0003] The prior art usually uses visual inspection or handheld clamps or collimators to assist in measuring the elevation angle of medical beds. The measurement accuracy is low and the operation is inconvenient. It requires two people to cooperate in the measurement at the same time and cannot be operated alone. It is not possible to intuitively see the precise angle of the bed head elevation, which is time-consuming and labor-intensive. In special scenarios such as intensive care, anesthesia surgery, etc., it is particularly important to accurately control the elevation angle of the bed head in order to prevent the occurrence of ventilator-associated pneumonia (VAP) in patients; to improve intestinal peristalsis, reduce food reflux, and prevent aspiration in patients with enteral nutrition through indwelling gastric tubes; and to localize the infection in patients during abdominal drainage. Therefore, the present invention proposes an instrument for accurately measuring the elevation angle of the medical bed head to solve such problems. Summary of the invention

[0004] The present invention aims to provide an apparatus for accurately measuring the elevation angle of a medical bed head, so as to solve the problem that the measurement accuracy is low and the operation is inconvenient when measuring the elevation angle of the medical bed head in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] The basic technical solution provided by the present invention is: an instrument for accurately measuring the elevation angle of a medical bedside, comprising a mounting frame and a headboard, the headboard is rotatably connected to the mounting frame, the headboard is fixedly connected with a mounting seat 1, the mounting seat 1 is rotatably connected with an adjusting rod, the support frame is fixedly connected with a mounting seat 2, the mounting seat 2 is rotatably connected with a mounting sleeve, the mounting sleeve is rotatably connected with a threaded sleeve, and the threaded sleeve is connected to the adjusting rod through a thread; the rotating shaft of the headboard is fixedly connected with a driving bevel gear, the support frame is rotatably connected with a transmission rod, one end of the transmission rod is fixedly connected with a driven bevel gear meshing with the driving bevel gear, the other end of the transmission rod is fixedly connected with a driving wheel, the support frame is rotatably connected with a rotating rod, the rotating rod is fixedly connected with a driven wheel, the driven wheel is connected to the driving wheel through a transmission belt, the rotating rod is fixedly connected with a pointer, and the support frame is fixedly connected with a measuring plate matching with the pointer.

[0007] The principle of the basic technical solution: when the angle of the headboard needs to be adjusted, the threaded sleeve is used as a drive, and the adjusting rod is driven to move by rotating the threaded sleeve. The adjusting rod drives the mounting seat to move, thereby controlling the rotation of the headboard to change its angle. The design of the mounting sleeve enables the threaded sleeve to make adaptive changes following the change in the angle of the adjusting rod; when the headboard rotates, it drives the active bevel gear to rotate, and the active bevel gear drives the active wheel to rotate through the transmission rod. The active wheel controls the rotation of the driven wheel through the transmission belt, thereby driving the rotating rod to rotate, so that the pointer performs a circular motion around the measuring plate, and the corresponding value is read out by comparing the scale line of the measuring plate with the pointer to obtain the rotation angle of the headboard.

[0008] The beneficial effect of the basic technical solution is: the diameter of the driving wheel is larger than the diameter of the driven wheel, so that the rotational angular velocity of the driven wheel is greater than the rotational angular velocity of the driving wheel, thereby amplifying the rotation angle of the headboard, and then improving the accuracy of the rotation angle of the headboard, which is convenient for measuring the elevation angle of the medical bed head. At the same time, the user can observe the angle while adjusting the angle, which is simple to operate and has high accuracy, and is easy to use.

[0009] Preferably, the measuring plate is fixedly connected to a mounting plate, the mounting plate array is provided with a plurality of groups of slide grooves, the slide grooves are slidably connected to sliders, a pressure spring is arranged between the lower surface of the mounting plate and the slider, the slide groove is provided with an elastic sheet, the elastic sheet is located above the slider, the mounting plate is provided with a plurality of groups of prompters, the prompters are located above the elastic sheet, the pointer is fixedly connected with a protrusion, the upper surface of the protrusion is tangent to the lower surface of the slider.

[0010] Through the above arrangement, the elastic sheet is connected to the negative pole of the power supply, and the indicator is connected to the positive pole of the power supply. When the pointer rotates to a certain angle, the protrusion generates a tangential force on the slider to drive the slider to move toward the elastic sheet, thereby pushing the elastic sheet to move and make it contact with the indicator, thereby controlling the power supply of the indicator to be in a closed state, achieving the effect of running the indicator, and giving corresponding prompts to the user.

[0011] Preferably, the support frame is provided with a mounting groove, the mounting groove is provided with a mounting cover, a battery is provided in the mounting groove, and the battery is electrically connected to the prompter to provide power for it.

[0012] Through the above arrangement, the reminder is powered by a battery, and the battery can be replaced by opening the installation cover.

[0013] Preferably, the support frame is provided with a control module, and the control module is electrically connected to the prompter to control its operation.

[0014] Through the above settings, the working mode of the indicator can be adjusted through the control module, so that the indicator can display a corresponding state during operation, that is, make a sound or display a specific color, so as to facilitate the user to judge the rotation angle of the pointer.

[0015] Preferably, the rotation angle of the headboard is 0-90 degrees.

[0016] Through the above settings, the headboard can achieve free rotation of 0-90 degrees, which greatly improves the flexibility and comfort of the bed. The angle of the headboard can be adjusted according to different needs and usage scenarios.

[0017] Preferably, the transmission ratio between the driving bevel gear and the driven bevel gear is 1:1, and the transmission ratio between the radius of the driving wheel and the driven wheel is 1:4.

[0018] Through the above settings, the headboard rotates 90 degrees, the driving wheel rotates 1 / 4 circle, and the driven wheel rotates 1 circle, which is exactly 360 degrees, which is conducive to the corresponding planning of the scale lines of the measuring plate and the improvement of its measurement accuracy.
