Description

Technical Field

[0001] The present invention belongs to the technical field of medical beds, and more specifically, particularly relates to a device for displaying the height of a bedside elevation. Background Art

[0002] Nursing beds are generally powered beds, divided into electric or manual nursing beds. They are designed according to the patient's bedridden lifestyle and treatment needs, and are designed so that family members can accompany them. They have multiple nursing functions and operation buttons, and are insulated and safe. Such functions include weight monitoring, back-up for meals, timed turning over alarm, prevention of bedsores, negative pressure urine absorption bedwetting alarm, mobile transportation, rest, rehabilitation (passive movement, standing), infusion and medication, and related prompts. They can prevent patients from falling out of bed. Rehabilitation nursing beds can be used alone or in conjunction with treatment or rehabilitation equipment. Turnover nursing beds are generally no more than 90cm wide, and are single-person single-layer beds. They are convenient for medical observation and inspection and family members to operate and use. They can be used by sick people, severely disabled people, the elderly, and healthy people during hospitalization or home treatment and rehabilitation. They come in a variety of sizes and forms.

[0003] Based on the above, the inventors have found the following problems: With the continuous advancement of medical technology and the improvement of patient care needs, electric beds have been widely used in medical institutions. Electric beds have the function of flexibly adjusting the height of the head of the bed to meet the treatment and care needs of different patients. However, when adjusting the height of the head of the bed, existing electric beds often lack an intuitive degree display device. Medical staff or family members can only rely on experience or roughly estimate the angle of the head of the bed, which is not conducive to accurate care and observation of the patient's condition.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a bedside height display device is provided to achieve a more practical purpose. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a bedside elevation height display device to solve the problem that current electric beds often lack an intuitive degree display device when adjusting the bedside height, and medical staff or family members can only rely on experience or roughly estimate the angle of bedside elevation.

[0006] The purpose and effect of the bedside elevation height display device of the present invention are achieved by the following specific technical means:

[0007] A device for displaying the height of a bed head, comprising a bed frame, a bed board being arranged on the bed frame, a central axis being arranged on the bed frame, a back plate being movably connected to the bed frame via the central axis, a support plate being installed at one end of the bed frame located below the back plate, a fixing plate being arranged on the supporting plate, a rotating shaft being rotatably installed on the fixing plate, a connecting piece being installed on the rotating shaft, a limiting groove being provided on the connecting piece, a pushing rack being movably installed inside the limiting groove, the upper end of the pushing rack being movably connected to one end of the back plate, and an inclinometer being installed on the fixing plate.

[0008] Furthermore, the number of the connecting member and the pushing rack is two, the two pushing racks are arranged opposite to each other, and the widths of the two pushing racks are adapted to the limiting grooves.

[0009] Furthermore, a movable shaft is installed at one end of the back plate, and the back plate is movably connected to a rotating member through the movable shaft, and the lower parts of the two pushing racks are connected to the rotating member.

[0010] Furthermore, a rotating shaft is installed on the fixed plate, a gear is installed on the rotating shaft, and the gear is located on the inner side of the two fixed plates.

[0011] Furthermore, the number of the gears is two, and the two gears are meshedly connected with the tooth openings of the two pushing racks.

[0012] Furthermore, one end of the rotating shaft is connected to a driving motor, an output end of the driving motor is transmission-connected to the rotating shaft, and the driving motor is connected to a fixed plate.

[0013] Furthermore, one end of the rotating shaft is connected to an inclinometer, a computing module is provided on the supporting plate, and the computing module is connected to the inclinometer.

[0014] Furthermore, when the backboard is flush with the bed board, an installation space is formed between the backboard and the support plate, the computing module is located inside the installation space, a plurality of heat dissipation grooves are provided on the support plate, and the computing module is located above the heat dissipation grooves.

[0015] Furthermore, the calculation module includes the following steps:

[0016] S1: When the rotating shaft rotates, the inclinometer records the rotation angle of the rotating shaft, and the inclinometer inputs the data into the calculation module. The calculation module first reads the initial azimuth angle of the rotating shaft, and then reads the output angle of the inclinometer, and solves the initial tilt angle through the calculation module;

[0017] S2: After the solution is completed, the new azimuth angle and the tilt angle are compared with the initial azimuth angle, and the calculation module solves the new azimuth angle and the tilt angle. After the solution is completed, the new azimuth angle and the tilt angle are output to the display device, and the calculated tilt angle is displayed on the display device;

[0018] S3: When the angle of the backrest needs to be adjusted again, the adjusted angle is compared with the previous angle, and then the new azimuth angle and tilt angle are solved again. After the solution is completed, they are output to the display device, and the tilt angle calculated by the second adjustment is displayed through the display device.

[0019] Furthermore, the inclinometer includes the following solution steps:

[0020] S1: The inclinometer has a built-in microprocessor, which is provided with an information processing module and a parameter storage module. When the inclinometer is working, it receives a pulse signal, and the microprocessor works at this time to transmit the position information of the rotating shaft before moving to the parameter storage module for subsequent use. After the rotating shaft rotates to the appropriate position, the position information after moving is transmitted to the microprocessor.

[0021] S2: After receiving the position information after the movement, the microprocessor retrieves the position information before the movement from the parameter storage module through the information processing module, and then compares the position information before the movement with the position information after the movement through the comparison module to obtain the angle value after the movement.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, when the rotating shaft rotates, the inclinometer records the rotation angle of the rotating shaft, and the inclinometer inputs the data into the calculation module. The calculation module first reads the initial azimuth angle of the rotating shaft, and then reads the output angle of the inclinometer. The initial tilt angle is solved by the calculation module, and after the solution is completed, it is output to the display device, and the calculated tilt angle is displayed by the display device.

[0024] The present invention realizes precise control and display of the lifting angle of the head of an electric bed. Its technical principle is mainly based on the combination of mechanical transmission and digital display technology. By installing a computing module in the head adjustment mechanism of the electric bed, the lifting angle of the head of the bed is detected in real time, and the angle signal is converted into an electrical signal and transmitted to the digital display module. Finally, the degree of head of bed lifting is intuitively displayed on the display. The head of bed lifting angle can be monitored and displayed in real time, ensuring the accuracy and convenience of the adjustment process. BRIEF DESCRIPTION OF THE DRAWINGS
