Description

Technical Field

[0001] This utility model relates to the field of angle adjustment reminder technology, specifically a hospital bed angle adjustment reminder device. Background Technology

[0002] Hospital bed angle adjustment is mainly achieved through the bed's built-in adjustment system. Its core function is to precisely adjust the tilt angle of the bed surface (such as the head, foot, and middle of the bed) according to the patient's treatment, nursing, or comfort needs. Common adjustment scenarios include raising the head of the bed (semi-reclining position), raising the foot of the bed (knee-bent position), and overall tilting. Hospital beds need to use a reminder device to remind patients when adjusting them.

[0003] Chinese Patent No. 202420761593.2 discloses a reminder device for adjusting the angle of a hospital bed, including a fixed suction foot, a rotating suction foot rotatably mounted on one end of the fixed suction foot, and a storage battery inside one end of the fixed suction foot. A reminder mechanism is provided at one end of the fixed suction foot and the rotating suction foot to remind the user after the bed body is rotated to a certain angle.

[0004] When using this invention, it is impossible to know the rotation angle in a timely manner, and it is also impossible to measure the body shape in real time. Utility Model Content

[0005] The purpose of this invention is to provide a reminder device for adjusting the angle of a hospital bed, in order to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hospital bed angle adjustment reminder device, comprising an angle adjustment reminder device; the angle adjustment reminder device consists of a rotating disk and a fixed disk, one end of the rotating disk is rotatably mounted on the upper side of the fixed disk, a rotation angle sensor is mounted on the outer side of the fixed disk, one end of the rotating disk is mounted inside the rotation angle sensor, one end of the rotation angle sensor is mounted with a wire, the other end of the wire is mounted on the upper side of a controller, a voice player is mounted on the upper side of the controller, a first mounting strip is mounted on one side of the fixed disk, a second mounting strip is mounted on the other side of the rotating disk, mounting plates are mounted on both sides of the first and second mounting strips, the mounting plates are mounted on the upper side of the bed, and the mounting plates, when installed, ensure that the rotation position of the bed is on the same straight line as the shaft.

[0007] Preferably, the calibration mechanism consists of a pointer line and a scale, with the scale marked on the upper side of the fixed disk and the pointer line marked on the upper side of the rotating disk.

[0008] Preferably, a soft metal pad is provided on the inner side of the mounting plate, and the soft metal pad is welded to the inner side of the mounting plate.

[0009] Preferably, a display is mounted on the upper side of the controller, and control buttons are mounted on the upper side of the controller below the display.

[0010] Preferably, a spring wire is provided in the middle of the conductor, and the spring wire is integrally formed with the conductor.

[0011] Preferably, the outer side of the conductor is wrapped with a wear-resistant mesh, which is adhered to the outer side of the conductor with adhesive.

[0012] Preferably, an emergency stop switch is provided on the upper side of the controller, and the emergency stop switch is electrically connected to the lifting mechanism through a wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The rotation angle sensor captures the rotation angle change of the rotating disk in real time and converts the angle change into an electrical signal. The electrical signal is transmitted to the controller through the wire connected to one end of the sensor. The controller analyzes and processes the electrical signal. If the angle reaches the preset reminder threshold, the controller will trigger the voice player installed on the upper side to play the preset voice reminder to inform the medical staff or patient of the current angle. 2. The scale in the calibration mechanism is marked on the upper side of the fixed plate, and the pointer line is marked on the upper side of the rotating plate. The two form an intuitive mechanical angle marking structure. When the rotating plate rotates with the hospital bed, the pointer line on the rotating plate will rotate synchronously around the scale on the fixed plate. Medical staff can directly obtain the actual rotation angle of the hospital bed by observing the corresponding scale on the scale of the pointer line. This allows for the calibration of the data collected by the rotation angle sensor. For example, if there is a deviation between the angle displayed by the sensor and the corresponding scale of the pointer line, medical staff can adjust the sensor parameters or the installation position of the device according to the matching relationship between the pointer line and the scale to ensure the accuracy of angle detection and avoid inaccurate voice prompts due to sensor errors. This provides a double verification basis for angle adjustment. 3. The display and control buttons installed on the upper side of the controller form the human-machine interface of the device. When the rotation angle sensor transmits the angle signal to the controller, the controller will not only trigger the voice reminder, but also display the processed angle data on the display in real time. Medical staff and patients can intuitively view the current precise angle of the bed through the display, which meets the needs of scenarios with higher requirements for angle accuracy. The control buttons located below the display can be used to set the angle reminder threshold, turn the voice reminder function on / off, switch the angle display unit, etc. 4. The wear-resistant mesh attached to the outside of the conductor with adhesive provides a reliable protective barrier for the conductor. In hospital settings, people move around the bed frequently, and the conductor may rub against the bed frame, medical equipment, clothing, etc. Long-term friction can easily cause damage to the outer insulation of the conductor, leading to problems such as leakage or signal transmission interruption. The wear-resistant mesh is usually made of high-strength fiber and has excellent wear resistance. It can directly withstand external friction forces and reduce the wear of the conductor insulation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5In this embodiment of the utility model, a hospital bed angle adjustment reminder device includes an angle adjustment reminder device 1. The angle adjustment reminder device 1 consists of a rotating disk 8 and a fixed disk 3. One end of the rotating disk 8 is rotatably mounted on the upper side of the fixed disk 3. A rotation angle sensor 12 is mounted on the outer side of the fixed disk 3. One end of the rotating disk 8 is mounted inside the rotation angle sensor. One end of the rotation angle sensor 12 is mounted with a wire 13. The other end of the wire 13 is mounted on the upper side of a controller 14. A voice player 17 is mounted on the upper side of the controller 14. A first mounting strip 2 is mounted on one side of the fixed disk 3, and a second mounting strip 11 is mounted on the other side of the rotating disk 8. Mounting plates 6 are mounted on both sides of the first mounting strip 2 and the second mounting strip 11. The mounting plates 6 are mounted on the upper side of the bed. When the mounting plates 6 are installed, the rotation position of the bed is aligned with the shaft 4.

[0018] The calibration mechanism 5 consists of a pointer line 10 and a scale 9. The scale 9 is marked on the upper side of the fixed disk 3, and the pointer line 10 is marked on the upper side of the rotating disk 8. The scale 9 in the calibration mechanism 5 is marked on the upper side of the fixed disk 3, and the pointer line 10 is marked on the upper side of the rotating disk 8. The two form an intuitive mechanical angle marking structure. When the rotating disk 8 rotates with the hospital bed, the pointer line 10 on the rotating disk 8 will rotate synchronously around the scale 9 on the fixed disk 3. Medical staff can directly obtain the actual rotation angle of the hospital bed by observing the scale corresponding to the pointer line 10 on the scale 9. This allows for the calibration of the data collected by the rotation angle sensor 12. For example, if there is a deviation between the angle displayed by the sensor and the scale corresponding to the pointer line 10, medical staff can adjust the sensor parameters or the installation position of the device according to the matching relationship between the pointer line 10 and the scale 9 to ensure the accuracy of angle detection and avoid inaccurate voice prompts due to sensor errors. This provides a dual verification basis for angle adjustment.

[0019] A soft metal pad 7 is provided on the inner side of the mounting plate 6. The soft metal pad 7 is welded to the inner side of the mounting plate 6. The soft metal pad 7 welded to the inner side of the mounting plate 6 plays a key role when the device is fixed to the bed frame through the mounting plate 6. Since the bed frame material and surface flatness may vary in different hospitals, the soft metal pad 7 has a certain degree of plasticity and flexibility, which can closely fit the bed frame surface and fill the small gaps between the mounting plate 6 and the bed frame. On the one hand, it can enhance the friction between the mounting plate 6 and the bed frame, prevent the device from shifting due to vibration or collision during the use of the bed, and ensure the stability of the device installation. On the other hand, the soft metal pad 7 can buffer the pressure of the mounting plate 6 on the bed frame surface, avoid the mounting plate 6 directly contacting the bed frame and causing scratches or damage, protect the appearance and structural integrity of the bed frame, and at the same time reduce the impact of bed frame vibration on the internal components of the device, such as sensors and controllers 14, and extend the service life of the device.

[0020] A display 15 is mounted on the upper side of the controller 14, and control buttons 16 are mounted on the upper side of the controller 14 below the display 15. The display 15 and control buttons 16 on the upper side of the controller 14 constitute the human-machine interface of the device. When the rotation angle sensor 12 transmits the angle signal to the controller 14, the controller 14 will not only trigger the voice reminder, but also display the processed angle data on the display 15 in real time. Medical staff and patients can intuitively view the current precise angle of the bed through the display 15, which meets the needs of scenarios with higher requirements for angle accuracy. The control buttons 16 located below the display 15 can be used to set the angle reminder threshold, turn the voice reminder function on / off, and switch the angle display unit such as degrees and radians.

[0021] A spring wire 19 is integrated into the middle of the wire 13. This integrated spring wire 19 is adapted to the motion characteristics of the rotating disk 8 as it rotates with the hospital bed. During the adjustment of the hospital bed angle, the rotating disk 8 will continuously rotate around the fixed disk 3, causing the wire 13 connecting the rotation angle sensor 12 and the controller 14 to extend, retract, or bend along with the movement of the rotating disk 8. The spring wire 19 has good elasticity and elasticity. When the rotating disk 8 rotates clockwise, the spring wire 19 will stretch accordingly; when the rotating disk 8 rotates counterclockwise to reset, the spring wire 19 will retract to its original length due to its own elasticity. This design can effectively prevent the wire 13 from getting tangled, pulled, or broken due to the rotation of the rotating disk 8, ensuring that the wire 13 always maintains a smooth signal transmission channel, preventing the loss of angle signal due to wire 13 failure, ensuring the controller 14's real-time reception and processing of angle data, and maintaining the stable operation of the device.

[0022] The outer side of the conductor 13 is wrapped with a wear-resistant mesh 20, which is attached to the outside of the conductor 13 with adhesive. The wear-resistant mesh 20 attached to the outside of the conductor 13 with adhesive provides a reliable protective barrier for the conductor 13. In hospital settings, people move around the bed frequently, and the conductor 13 may rub against the bed frame, medical equipment, clothing, etc. Long-term friction can easily cause damage to the outer insulation of the conductor 13, leading to problems such as leakage or signal transmission interruption. The wear-resistant mesh 20 is usually made of high-strength fibers such as nylon and polyester, which has excellent wear resistance and can directly withstand external friction forces, reducing the wear of the insulation of the conductor 13.

[0023] An emergency stop switch 18 is installed on the upper side of the controller 14. The emergency stop switch 18 is electrically connected to the lifting mechanism through the wire 13. The emergency stop switch 18 installed on the upper side of the controller 14 and the lifting mechanism through the wire 13 form a safety emergency control circuit of the device. During the adjustment of the bed angle, if an emergency occurs, such as angle sensor failure causing angle loss of control, patient discomfort requiring immediate cessation of adjustment, or abnormal jamming of the lifting mechanism, medical staff can quickly press the emergency stop switch 18. After the emergency stop switch 18 is triggered, it will immediately cut off the power supply circuit of the lifting mechanism, causing the lifting mechanism to stop all movement, thereby preventing the bed angle from continuing to change. This design can quickly terminate dangerous operations in emergency situations, avoid injury to the patient due to abnormal angle adjustment such as squeezing or falling, or prevent equipment damage due to continuous abnormal operation of the lifting mechanism. It provides key safety protection for the bed angle adjustment process and meets the safe use requirements of hospital equipment.

[0024] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the angle of the hospital bed, since one end of the rotating disk 8 is mounted on the fixed disk 3, the rotation of the bed will drive the rotating disk 8 to rotate synchronously around the shaft on the fixed disk 3. At this time, the rotation angle sensor 12, which is installed on the outside of the fixed disk 3 and connected to one end of the rotating disk 8, will capture the change in the rotation angle of the rotating disk 8 in real time and convert the angle change into an electrical signal. This electrical signal is transmitted to the controller 14 through the wire 13 connected to one end of the sensor. The controller 14 analyzes and processes the electrical signal. If the angle reaches the preset reminder threshold, the controller 14 will trigger the voice player 17 installed on the upper side to play the preset voice reminder to inform the medical staff or patient of the current angle. At the same time, the first mounting strip 2 and the second mounting strip 11 are fixed to the bed body through the mounting plates 6 on both sides. During installation, it is ensured that the rotation position of the bed body is on the same straight line as the shaft 4. This installation design can ensure the synchronous rotation of the rotating disk 8 and the bed body, avoid inaccurate detection of the angle sensor due to position deviation, and ensure the accuracy of angle data acquisition and reminder functions.

[0025] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
