Description

Technical Field

[0001] This utility model relates to the technical field of smart elderly care safety monitoring equipment, and in particular to a smart elderly care nighttime safety monitoring device. Background Technology

[0002] Nursing beds or senior care beds are widely used in elderly care institutions, hospital care, and home care settings. To reduce the risk of elderly people falling off the bed while resting, existing nursing beds or senior care beds usually have adjustable or retractable bed rails on both sides of the bed to provide bedside protection when the elderly are resting.

[0003] In actual use, elderly people usually need to lower the bed rails when getting out of bed at night. Due to the dim light at night, the elderly are prone to bumping into things, missing a step, or tripping when getting out of bed because they cannot see the surrounding environment clearly. At the same time, after returning to bed, the elderly may not promptly restore the bed rails to their protective state due to drowsiness, difficulty moving, or lack of attention, thus reducing the effectiveness of bedside protection.

[0004] While existing elderly care beds or nursing beds can provide protection, lighting, call functions, or monitoring through bed rails, nightlights, call buttons, or cameras, these functions are usually relatively independent and cannot promptly reflect changes in the bed rails' condition after nighttime use. Therefore, it is necessary to improve the safety warning structure for nighttime use of existing elderly care beds or nursing beds. Utility Model Content

[0005] The technical problem this utility model aims to solve is that: when elderly people use existing nursing beds or care beds at night, they need to find or operate additional lighting equipment when they get out of bed after lowering the bed rails, which is inconvenient; and if the bed rails are not restored to the protective state in time after the elderly return to bed, it is not easy for caregivers to notice in time.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a smart elderly care nighttime safety monitoring device, including a bed body and bed rails disposed on both sides of the bed body. The bed rails include a horizontal bar and multiple vertical bars connected to the horizontal bar. The bed rails are provided with an unlocking device, which is used to switch the bed rails between an upright state and a lowered state. A trigger is provided on one side of the bed rails, which is linked to the opening and closing of the bed rails. The bed body is provided with a monitor and a light. The trigger is electrically connected to the light and switches from a disconnected state to a conductive state when the bed rails switch from an upright state to a lowered state, so as to turn on the light. The monitor is electrically connected to the trigger and is used to monitor the conductive state of the trigger.

[0007] Furthermore, the trigger is provided with a mounting base, which is located on one side of the bed rail; the unlocking component is provided with a pressure plate, which is movably mounted on the mounting base.

[0008] Furthermore, the trigger is provided with a spring, which is disposed between the pressure plate and the mounting base; the pressure plate is provided with a locking guide groove, and the mounting base is provided with a guide rod, which extends into the locking guide groove so that when the pressure plate moves, it drives the guide rod to slide in the locking guide groove.

[0009] Furthermore, the mounting base is provided with a guide groove, and the pressure plate is slidably disposed in the guide groove; the locking guide groove includes a connecting guide section and a locking section, so that the pressure plate is held in the disconnected position after it moves up, and is released when the bed rail is lowered in linkage.

[0010] Furthermore, the unlocking component is provided with an electrical contact, which is disposed on the pressure plate; the triggering component is provided with an electrical spring, which is disposed on the mounting base and corresponds to the electrical contact; when the guide rod is located at the bottom of the locking guide groove, the electrical contact is disconnected from the electrical spring; when the bed rail is lowered and drives the guide rod to slide in the locking guide groove, the electrical contact and the electrical spring make contact and conduct.

[0011] Furthermore, after the bed rail is restored to the upright position, the pressure plate can be pressed back to its original position, and under the action of the spring, it will drive the guide rod back to the disconnected position of the locking guide groove, so that the electrical contact is separated from the electrical spring and the lighting is turned off.

[0012] Furthermore, the monitor is equipped with a time relay, which is used to drive the monitor to issue an alarm signal and start video monitoring after the electrical contact and the electrical spring have been in continuous contact for a set time.

[0013] Furthermore, the lighting lamp is mounted on the bed frame and arranged along the length of the bed frame so that the lighting direction of the lighting lamp is parallel to the bed frame.

[0014] The beneficial effects of this utility model are as follows: when the elderly lower the bed rails at night, the lighting can be turned on when the trigger is activated, making it easier for the elderly to get out of bed and move around; the monitor can monitor the activation status of the trigger and issue an alarm signal and activate video monitoring after the continuous activation reaches a set time, making it easier for caregivers to know when the bed rails are in the lowered state for a long time; the lighting is arranged along the length of the bed, which is beneficial for illuminating the side area of ​​the bed.

[0016] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0017] like Figures 1 to 5 As shown, this embodiment of a smart elderly care nighttime safety monitoring device includes a bed frame 1, bed rails 2 on both sides of the bed frame 1, a monitor 4 and a light 5 on the bed frame 1, and a trigger 3 on one side of the bed rail 2. The bed frame 1 is the main load-bearing structure of the elderly care bed or nursing bed. The bed frame 1 includes a bed frame, a bed surface support, and a mattress support. The bed frame 1 can be an electric nursing bed structure or a manual nursing bed structure. In this embodiment, the lifting, backrest adjustment, and legboard adjustment structures of the bed frame 1 are not modified. The trigger 3, monitor 4, and light 5 can be added to the existing nursing bed to turn on the light when the bed rail 2 is lowered and to monitor the conduction status of the trigger 3. The bed rails 2 are set on both sides of the bed frame 1 to provide protection for the bedside when the elderly are resting in bed. The two bed rails 2 can adopt the same structure. This embodiment describes the bed rail 2 with the trigger 3 on one side as an example. The other bed rail 2 can maintain its conventional protective function.

[0018] The bed rail 2 includes a crossbar 22 and multiple uprights 21 connected to the crossbar 22. The uprights 21 are spaced apart along the length of the bed frame 1. The lower ends of the uprights 21 engage with the side guide structure of the bed frame 1. The crossbar 22 is located at the upper end of the uprights 21 and connects the uprights 21 into a whole. The crossbar 22 and the uprights 21 can be welded, screwed, or plugged into a locking structure to form a stable connection, giving the bed rail 2 sufficient rigidity when upright. The bed rail 2 is equipped with an unlocking device 24, which is used to switch the bed rail 2 between the upright and lowered states. In use, pulling the crossbar 22 upwards causes the uprights 21 to move upwards simultaneously, switching the bed rail 2 from the lowered state to the upright state. When the bed rail 2 rises to a predetermined position, the locking structure corresponding to the unlocking device 24 holds the bed rail 2 in the upright state. When it is necessary to lower the bed rail 2, the unlocking device 24 is operated to release the lock, and then the horizontal bar 22 is pressed down to make the multiple uprights 21 move down synchronously, and the bed rail 2 returns to the lowered state. When the elderly need to get out of bed and lower the bed rail 2 at night, this embodiment uses a trigger 3 set on one side of the bed rail 2 to switch states with the opening and closing of the bed rail 2, thereby turning on the light 5 when the bed rail 2 is lowered, and enabling the monitor 4 to monitor the conduction state of the trigger 3.

[0019] The trigger 3 is located on one side of the bed rail 2, preferably at the lower part of the bed rail 2 on the side where the elderly person frequently gets up, near the control area of ​​the crossbar 22 and associated with the operating part of the unlocking element 24. The trigger 3 includes a mounting base 32, which is fixedly mounted on one side of the bed rail 2. The mounting base 32 can be fixed to the side structure of the bed rail 2 by screws, rivets, welded connecting pieces, or snap-fit ​​clamps, preferably fixed near the unlocking element 24, so that the trigger 3 can be activated when the unlocking element 24 is actuated. The mounting base 32 is a hollow shell structure, forming an installation cavity for the pressure plate 31 and a guide movement space inside. The mounting base 32 is provided with a guide groove, which extends along the predetermined movement direction of the pressure plate 31. The groove wall of the guide groove forms a sliding guide constraint on the pressure plate 31, so that the pressure plate 31 remains stable in position during reciprocating motion. The mounting base 32 can be made of insulating engineering plastic, aluminum alloy, or steel with anti-corrosion surface treatment. Using insulating materials is beneficial for the insulation and isolation of the electrical contacts 36 and the electrical springs 37. When using metal materials, an insulating bushing or insulating mounting plate can be set on the inner side. The outer contour of the mounting base 32 can be designed as a long box shape, a box shape with arc edges, or a rounded rectangular shell. The outer surface is preferably rounded and blunted to avoid discomfort from bumps during use.

[0020] The unlocking component 24 includes a pressure plate 31, which is movably mounted on the mounting base 32. The pressure plate 31 is preferably a plate-shaped or block-shaped pressing component, with its exposed surface located on the outside of the mounting base 32 for easy pressing by the elderly or caregivers. The side of the pressure plate 31 facing the interior of the mounting base 32 has a locking guide groove 34. A guide rod 35 is fixedly mounted on the mounting base 32, extending into the locking guide groove 34. When the pressure plate 31 moves relative to the mounting base 32, the locking guide groove 34 moves synchronously with the pressure plate 31 and slides relative to the guide rod 35, thus limiting the switching of the pressure plate 31 between the open and closed positions. A spring 33 is provided between the pressure plate 31 and the mounting base 32, providing a restoring force to the pressure plate 31. Spring 33 can be a compression spring, arranged along the moving direction of pressure plate 31, with one end abutting against the inner support surface of pressure plate 31 and the other end abutting against the inner support surface of mounting base 32. When pressure plate 31 moves under external force, spring 33 is compressed; after the external force is released, spring 33 pushes pressure plate 31 back to the corresponding position. Pressure plate 31 can be made of engineering plastic, insulating resin, or metal with a soft coating. The outer surface of pressure plate 31 is preferably designed as a large-area pressing surface, which can be flat, slightly curved, or have anti-slip texture, facilitating pressing operations in low-visibility conditions at night. The edges of pressure plate 31 can be rounded, and the thickness of pressure plate 31 matches the width of the guide groove of mounting base 32, allowing pressure plate 31 to move stably along the guide groove without significant shaking.

[0021] A locking guide groove 34 is provided on the pressure plate 31. The locking guide groove 34 includes a connecting guide section and a locking section. The guide section extends along the main moving direction of the pressure plate 31, and the locking section is connected to the guide section and offset from the guide section to form a locking position. During the upward movement or reset of the pressure plate 31, the locking guide groove 34 moves relative to the guide rod 35, so that the guide rod 35 is positioned relative to the guide section or the locking section. Before the elderly go to sleep or after the caregiver tidies up the bed, the bed rail 2 is pulled up to the upright position, and the pressure plate 31 is placed in the preset disconnect holding position. At this time, the guide rod 35 is positioned relative to the locking position of the locking guide groove 34 or the corresponding disconnect holding position. When the pressure plate 31 is held in this position, the electrical contact 36 is disconnected from the electrical spring 37, and the lighting lamp 5 remains off. This state is the standby state when the bed rail 2 is in the upright state, the bedside is protected, and the lighting lamp 5 is not working.

[0022] In this embodiment, the unlocking component 24 is provided with an electrical contact 36, which is mounted on the pressure plate 31; the triggering component 3 is provided with an electrical spring 37, which is mounted on the mounting base 32 and corresponds to the electrical contact 36. The electrical contact 36 and the electrical spring 37 constitute a conductive switch structure. The electrical contact 36 can be a copper alloy silver-plated contact or an elastic metal contact sheet, fixed at the bottom or inner side of the pressure plate 31 at a corresponding position; the electrical spring 37 is fixed inside the mounting base 32 and forms a crimp connection with the electrical contact 36 through its own elasticity. When the guide rod 35 is in the disconnected holding position relative to the locking guide groove 34, the pressure plate 31 remains in the disconnected position, there is a gap between the electrical contact 36 and the electrical spring 37, they are disconnected, and the lighting lamp 5 is not powered. When the elderly need to get out of bed at night, they first operate the unlocking component 24 to lower the bed rail 2. When the bed rail 2 is switched from the upright state to the lowered state, the unlocking component 24 moves in conjunction with the mounting base 32, causing the pressure plate 31 to release its locking mechanism. The locking guide groove 34 moves relative to the guide rod 35, and the pressure plate 31 returns to the conductive position under the action of the spring 33. The electrical contact 36 contacts the electrical spring 37 to conduct electricity, and the light 5 is turned on. Thus, lowering the bed rail 2 can simultaneously turn on the light 5, reducing the inconvenience for the elderly at night by having to search for the light switch.

[0023] The lighting lamp 5 is installed on the bed frame 1 and arranged along its length, with the lighting direction of the lamp 5 parallel to the bed frame 1. The lighting lamp 5 is preferably positioned below the side of the bed frame 1, on the outer side of the bed frame, or below the edge of the bed surface, so that the light is projected onto the ground and the side passage along the bedside area, rather than directly towards the elderly person's eyes. The lighting lamp 5 can be a linear light strip, a strip of soft light, a low-power light-emitting module with a diffuser, or a linear LED light. The housing of the lighting lamp 5 is preferably equipped with a light-shielding edge or a light-transmitting cover, with the cover being a frosted or milky white diffuser to softly diffuse the light. After the lighting lamp 5 is arranged along the length of the bed frame 1, the bedside floor, the bedside support area, and the path for the elderly person to get out of bed can be illuminated. The color temperature of the lighting lamp 5 can be set to warm white light or neutral warm light to reduce glare. The power of the lighting lamp 5 can be set to a low-power mode, turning on after the elderly person lowers the bed rail 2 to meet the nighttime lighting needs when getting out of bed.

[0024] The monitor 4 is mounted on the bed frame 1, preferably inside the control box at the head of the bed, on the side of the bed, or within the electrical control box area of ​​the nursing bed. The monitor 4 is electrically connected to the trigger 3 and is used to monitor the conduction status of the trigger 3. The monitor 4 may include a control circuit, a power management module, a time relay, a wireless communication module, a camera monitoring control interface, and an alarm output unit. The monitor 4 is equipped with a time relay, which drives the monitor 4 to issue an alarm signal and activate camera monitoring after the electrical contact 36 and the electrical spring 37 have been in continuous contact for a set time. This set time can be adjusted according to the usage scenario of the nursing bed, for example, set to a range of tens of seconds to several minutes, so that normal short-term use will not trigger an alarm, while the continuous conduction of the trigger 3 for the set time will enter the alarm judgment range of the monitor 4. The alarm signal can be an audible and visual reminder, a wireless call, a signal upload from the nursing station, a push notification from a mobile terminal, or an alarm linked to the hospital's monitoring system. Camera monitoring can be controlled by the monitor 4 to activate the bedside camera, the bedside camera, or the room's camera equipment, to assist monitoring personnel in viewing the situation at the bedside.

[0025] The operational flow during nighttime use by the elderly in this embodiment is as follows: Before the elderly person rests at night, the caregiver or the elderly person themselves pulls up the bed rail 2, making it upright and providing protection around the bed. Then, the pressure plate 31 is placed in the disconnected standby position, the guide rod 35 is positioned relative to the corresponding disconnected position of the locking guide groove 34, the electrical contact 36 separates from the electrical spring piece 37, the light 5 is turned off, and the monitor 4 is in standby monitoring mode. When the elderly person needs to get out of bed at night, they first operate the unlocking mechanism 24 to lower the bed rail 2. After the unlocking mechanism 24 is activated, the bed rail 2 switches from the upright state to the lowered state, the pressure plate 31 loses its original locking position and moves under the action of the spring 33, the locking guide groove 34 moves relative to the guide rod 35, the pressure plate 31 moves to the conductive position, the electrical contact 36 contacts the electrical spring piece 37, and the light 5 is turned on. After receiving illumination on the floor beside the bed, the elderly person can get out of bed, get up at night, turn over, or move around the bed. During this process, the monitor 4 begins recording the continuous contact time between the electrical contact 36 and the electrical spring piece 37. After the elderly person returns to the bedside after getting up at night, the light 5 remains on, indicating that the bed rail 2 or trigger 3 has not yet returned to the off state. The elderly person pulls the bed rail 2 back up to its upright position, then presses the pressure plate 31. The pressure plate 31, with the cooperation of the guide rod 35 and the locking guide groove 34, re-enters the off-hold position, the spring 33 is pre-compressed again, the electrical contact 36 separates from the electrical spring 37, the light 5 turns off, and the trigger 3 returns to the next standby state.

[0026] If the bed rail 2 is not promptly restored to its upright position after being lowered, or if the pressure plate 31 fails to reset, the electrical contact 36 and the electrical spring 37 will remain in continuous contact, and the time relay inside the monitor 4 will continuously time. When the continuous contact reaches the set time, the monitor 4 will issue an alarm signal and activate video monitoring. Video monitoring can be activated after the trigger 3 has been continuously conducting for the set time, assisting monitoring personnel in checking the situation around the bed. Through the coordination of the trigger 3 and the opening and closing action of the bed rail 2, the continuous status of the bed rail 2 after it has been lowered can be indicated.

[0027] The guide groove of the mounting base 32 is preferably a long groove structure extending along the moving direction of the pressure plate 31, and a sliding guide surface is formed between the guide groove and the side wall of the pressure plate 31. The guide groove can be set on the upper surface of the mounting base 32, the inner side of the side wall, or on a symmetrical guide rail structure. The bottom and wall of the guide groove are used to limit the movement direction of the pressure plate 31 and reduce the sway of the pressure plate 31 when subjected to oblique force. The locking guide groove 34 can be set as an L-shaped, zigzag, or groove-shaped structure with a rotary lock. The guide section is used to guide the movement of the pressure plate 31, and the locking section is used to form a retention after the pressure plate 31 moves upward. The guide rod 35 can be a cylindrical pin, a pin with rollers, or a limiting rod structure with a widened head. After the guide rod 35 extends into the locking guide groove 34, as the position of the pressure plate 31 changes, the locking guide groove 34 moves relative to the guide rod 35, and the mating boundary between the two limits the switching of the pressure plate 31 between the disconnected position and the connected position. The width of the locking guide groove 34 matches the outer diameter of the guide rod 35, ensuring smooth movement of the guide rod 35 relative to the locking guide groove 34 without excessive clearance. The groove opening and the edges of the guide rod 35 are preferably chamfered to improve handling and reduce wear.

[0028] The shape of the pressure plate 31 can be set as a long strip, a thumb-pressing block, or a plate structure with a curved tactile surface, depending on the operating habits. The exposed height of the pressure plate 31 should not be too small, so that the pressing position can still be found by hand in low visibility or dark environments at night. The outer surface of the pressure plate 31 can be provided with anti-slip texture, embossed texture, or soft rubber covering to improve the stability of finger contact. The stiffness of the spring 33 should meet two conditions: first, the pressure plate 31 can reliably return to the conductive position after the bed rail 2 is lowered and the linkage is released; second, the pressing force required to press the pressure plate 31 should not be too large. The spring 33 can be a stainless steel compression spring, a corrosion-resistant spring steel component, or a surface-plated spring component to adapt to the long-term service environment of the nursing bed. The electrical contact 36 and the electrical spring 37 are preferably conductive components with low contact resistance. The electrical spring 37 can be designed as a leaf spring structure to ensure sufficient contact pressure and reduce contact vibration when contact is made. The conductive boundary between the electrical contact 36 and the electrical spring 37 should be stably aligned with the position boundary of the pressure plate 31 to ensure that the lighting turns on at the same time and avoid false triggering or incomplete contact.

[0029] The time relay in monitor 4 can be an adjustable delay module, and monitor 4 can be set to a single-delay mode. In single-delay mode, an alarm is triggered after the electrical contact 36 and the electrical spring 37 have been in continuous contact for a set time. Monitor 4 can also be set with different delay times according to usage needs. Monitor 4 can be connected to the power supply of the nursing bed control system, or it can be equipped with an independent low-voltage backup power supply to ensure that it still has basic alarm functions in the event of a power outage or momentary power failure at night. The alarm output of monitor 4 can be connected to a bedside buzzer, nursing station receiver, ward call panel, or mobile terminal. If the nursing facility has a centralized monitoring system, monitor 4 can further upload the alarm signal to the monitoring platform wirelessly.

[0030] The lighting lamp 5 is preferably installed at the bottom edge of the bed frame 1, with the lamp body parallel to the bed frame 1, extending the illumination range along the edge of the bed to the ground. The length of the lighting lamp 5 can be set as a partial light strip or a near-full-length light strip depending on the size of the bed frame 1. The installation position of the lighting lamp 5 is offset from the elderly person's line of sight, so that the elderly person will not see the luminous surface directly when sitting up from the bed. The lighting lamp 5 can also be installed using recessed installation, snap-on installation, or screw fixing. To improve durability, the housing of the lighting lamp 5 can be made of flame-retardant material and equipped with a dust cover. For elderly people who need to get up frequently at night, the brightness of the lighting lamp 5 is adjustable, and caregivers can preset it according to the elderly person's vision and the ward environment.

[0031] In this embodiment, after the bed rail 2 is restored to the upright state, the pressure plate 31 can be pressed back, and under the action of the spring 33, the guide rod 35 returns to the open position of the locking guide groove 34, so that the electrical contact 36 separates from the electrical spring 37 and turns off the light 5. This action forms a continuous operation of resetting the bed rail 2 and turning off the light. If the elderly person does not pull up the bed rail 2 after returning to bed, the light 5 remains on, indicating that the bed rail 2 has not been restored; after the elderly person pulls up the bed rail 2, they can press the pressure plate 31 to separate the electrical contact 36 from the electrical spring 37, thereby turning off the light 5 and returning the trigger 3 to the open state. If the trigger 3 remains conductive for a set time, the monitor 4 issues an alarm signal.

[0032] In this embodiment, depending on the usage needs of the left and right sides of the bed 1, a trigger element 3 of the same structure can be installed on the other side of the bed rail 2 to achieve independent monitoring and lighting control on both sides; alternatively, the monitor 4 can be configured to uniformly control both trigger elements 3, monitoring the conduction status of the trigger elements 3 on both sides separately. For a bed 1 placed against a wall on one side, the trigger element 3 can also be installed only on the outer bed rail 2. Regardless of whether a single-sided or double-sided setting is adopted, the opening and closing linkage of the bed rail 2 serves as the trigger basis, enabling the lighting 5 to be turned on when the bed rail 2 is lowered, and allowing the monitor 4 to monitor the conduction status of the trigger element 3.

[0033] Through the above-described structure and action relationship, this embodiment can turn on the light 5 when the bed rail 2 is lowered, and issue an alarm signal and activate the camera monitoring after the trigger 3 has been continuously conducting for a set time. A linkage is formed between the bed rail 2, the trigger 3, the light 5, and the monitor 4, which can provide indication of the continuous status after the bed rail 2 is lowered.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
