Description

Technical Field

[0001] This utility model belongs to the field of medical assistive device technology, specifically relating to an intelligent lifting bed railing system. Background Technology

[0002] Currently, most hospital bed rails are manually raised and lowered using mechanical principles. For some patients with weak awareness of safety precautions, they often forget to pull the rails back up after lowering them. Relying solely on health guidance and regular rounds by medical staff is insufficient to meet clinical safety needs. This is especially true during midday and nighttime rest periods, which significantly increases the risk of falls and bed falls for patients, as well as the workload for nursing staff.

[0003] A search revealed that existing technology discloses a retractable guardrail with an alarm function (patent application number CN201721123716.6), mainly applicable to pediatric wards. It uses a pressure sensor on the side of the bed rail to detect abnormal pressure and trigger an alarm, but does not mention an automatic lifting function. Furthermore, an empty bed rail that is not raised might be mistaken for a temporary resting area; raising the rail promptly not only keeps the spare bed tidy but also improves new patients' satisfaction with the ward environment.

Detailed Implementation

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-6 As shown, an intelligent lifting bed railing system includes a lower crossbeam 1 and an upper crossbeam 2. Both the lower crossbeam 1 and the upper crossbeam 2 have hollow internal structures to reduce weight. The lower crossbeam 1 is fixed to both sides of the bed with screws. The top of the lower crossbeam 1 is evenly provided with docking cylinders 14. Electric push rods 15 are installed inside the two docking cylinders 14 located at the edge. The electric push rods 15 are lead screws controlled by a motor and adopt common models on the market. The upper crossbeam 2 is placed parallel above the lower crossbeam 1. The lower surface of the upper crossbeam 2 is evenly provided with lifting rods 22. The lifting rods 22 slide inside the docking cylinders 14. When the upper crossbeam 2 is lowered to the lowest point, its height is less than that of the bed. The two lifting rods 22 located at the edge have cavities 221 on their inner sides. A sealing plate 3 is installed at the bottom of the cavity 221 by bolts. The sealing plate 3 seals the bottom of the cavity 221. Half-opening nuts 4 are symmetrically slidably installed on the upper surface of the sealing plate 3. The two half-opening nuts 4 are combined to form a nut that meshes with the electric push rod 15. By controlling the movement of the two half-opening nuts 4, the engagement with the electric push rod 15 can be controlled to achieve the switching between automatic lifting and manual lifting.

[0017] like Figures 1-3As shown, pressure-sensitive stickers 21 are evenly distributed on the upper surface of the upper crossbeam 2. The pressure-sensitive stickers 21 are arrayed along the upper crossbeam 2. Pressure-sensitive stickers 21 are also provided on the handle 23 to prevent the electric push rod 15 from starting suddenly during manual control, thereby improving safety. The surface of the upper crossbeam 2 is covered with an antibacterial and anti-slip coating. The pressure-sensitive stickers 21 are electrically connected to the electric push rod 15.

[0018] like Figures 1-3 As shown, the lower crossbeam 1 has a built-in power supply 11 inside. The built-in power supply 11 is a rechargeable structure and can also be replaced by a plug. A voice broadcaster 13 is installed at one end of the lower crossbeam 1. The built-in power supply 11 is used to power the electric push rod 15 and the voice broadcaster 13. A power control button 12 is provided at the bottom of the lower crossbeam 1. The power control button 12 is used to switch the built-in power supply 11 on and off. The voice broadcaster 13 is used to remind the user by voice during lifting and lowering.

[0019] like Figures 4-6 As shown, the semi-open nut 4 is restricted on both sides by the inner wall of the cavity 221, so that the semi-open nut 4 can only slide laterally. A fixing bolt 41 is provided at the bottom of the semi-open nut 4. The sealing plate 3 has symmetrically opened sliding grooves 31. The fixing bolt 41 passes through the sliding grooves 31. A locking nut 42 is screwed at the bottom of the fixing bolt 41. The locking nut 42 is placed on the lower surface of the sealing plate 3. The sliding groove 31 is used to limit the sliding limit position of the semi-open nut 42. After being locked by the locking nut 42, the semi-open nut 42 and the sealing plate 3 can only move in opposite directions vertically. The sealing plate 3 and the lifting rod 22 are fixed by screws. Therefore, when the electric push rod 15 rotates to control the movement of the combined nut, it can drive the lifting rod 22 to perform lifting and lowering work.

[0020] like Figure 4 and Figure 6 As shown, a through hole 32 is provided in the center of the surface of the sealing plate 3, and the electric push rod 15 passes through the through hole 32. The diameter of the through hole 32 is slightly larger than that of the electric push rod 15. Two semi-open nuts 4 are each equipped with a spring 5 at one end opposite to each other. The other end of the spring 5 is in contact with the inner wall of the cavity 221. The spring 5 is used to apply a pushing force towards the center to the semi-open nuts 4 so that the two semi-open nuts 4 are in the closed state under normal conditions. The elastic force of the spring 5 must ensure that the two semi-open nuts 4 will not separate due to factors such as gravity compression during the lifting and lowering process.

[0021] like Figure 4 and Figure 5 As shown, the upper surface of the semi-open nut 4 is provided with a pressing wedge 43, and the distance between the tops of the two pressing wedges 43 is greater than the bottom. A slider 6 is vertically slidably mounted inside the cavity 221. Control extrusion rods 61 are symmetrically arranged at the bottom of the slider 6. The bottom of the two control extrusion rods 61 respectively contacts the inclined surfaces of the two extrusion blocks 43. When the slider 6 moves down, the two semi-open nuts 4 can be separated by the cooperation of the extrusion rods 61 and the extrusion blocks 43, so that they are no longer controlled by the electric push rod 15. It should be noted that the two extrusion rods 61 should be outside the cylindrical range of the through hole 32 to prevent the extrusion rods 61 from contacting the electric push rod 15 during operation.

[0022] like Figure 4 and Figure 5 As shown, a squeezing head 62 is provided at the top center of the slider 6. The top of the squeezing head 62 has a spherical structure. A sliding rod 7 is horizontally slidably installed between the roots of multiple lifting rods 22. The sliding rod 7 has a rectangular cross-section to ensure that the control hook 71 and the cone block 72 are always downward.

[0023] Among them, the lower surface of the slide rod 7 is symmetrically provided with cone blocks 72, which are in contact with the surface of the extrusion head 62. When the slide rod 7 moves, the slider 6 can be pressed downward by the cooperation of the two. Conversely, when there is no force, the inward extrusion force of the spring 5 causes the two half-open nuts 4 to approach each other, which in turn pushes the slider 6 to move upward, so that the slide rod 7 returns to its original position. A handle 23 is provided on the outer side of one edge of the lifting rod 22, and a control hook 71 is provided at the end of the slide rod 7. The control hook 71 is located below the handle 23, so that the slide rod 7 can be moved as a whole by pulling it through the control cabinet 71.

[0024] The specially designed intelligent recognition system can detect sudden changes in stress (such as a patient suddenly gripping or standing up). In this case, the system will immediately lock the current state and remain still, while prompting medical staff to come to the scene to handle the situation, ensuring safety and control in special circumstances.

[0025] The working principle of this utility model is as follows: The lower crossbeam 1 is fixed parallel to both sides of the hospital bed. Under normal conditions, due to the thrust applied by the spring 5 to the semi-open nuts 4, the two semi-open nuts 4 move closer to each other to form a closed nut. The two sides of the semi-open nuts 4 are limited by the inner wall of the cavity 221, and the fixing bolt 41 can only slide inside the slide groove 31. By locking the locking nut 42, the semi-open nuts 4 can only open and close. The combined closed nut cooperates with the electric push rod 15. When the system is activated by the pressure sensor... If the pressure sensor 21 detects that the pressure has been in a low-pressure state for a long time, it means that no one is using the device or the patient is lying still. The voice broadcaster 13 will then issue a prompt that the guardrail is about to rise. After that, the electric push rod 15 will be activated to control the upper beam 2 to rise through the cooperation of the electric push rod 15 and the combination nut. If the pressure sensed by the pressure sensor 21 exceeds the threshold, the electric push rod 15 will stop working. At this time, the upper beam 2 will stop rising and slowly descend to prevent injury. When the upper beam 2 reaches the highest point, the electric push rod 15 will stop rotating and lock in place. Hold the handle 23 and pull the control hook 71 to make the slide bar 7 slide horizontally. The cone block 72 squeezes the extrusion head 62, causing the slider 6 to move downward as a whole. The two control extrusion rods 61 squeeze the extrusion inclined block 43, causing the two semi-open nuts 4 to separate from each other. At this time, the electric push rod 15 cannot act on the upper crossbeam 2, so manual lifting can be performed to achieve quick manual operation in case of power failure or emergency. This structure can perform fully automatic lifting while retaining manual control, and can reduce the risk of pinching injury.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
