[0002] In medical care settings, hospital beds serve as core equipment for patient treatment and recuperation, and their safety and functionality directly impact the patient's recovery experience and nursing efficiency. Especially for postoperative patients, elderly patients, and individuals with impaired consciousness or mobility, fall-prevention bed design is a crucial requirement in clinical nursing.

[0003] Existing hospital beds mostly use a four-wheel omnidirectional wheel design, but lack a differentiated locking mechanism: it is difficult to turn when all wheels are locked at the same time, and the bed is prone to sliding due to uneven ground when unlocked. The beds have bed rails on both sides that can be raised and lowered, but there are certain gaps at the front and back of the bed rails on both sides. For relatively thin patients, or patients who are immobile or restless, the patient may slide to the ground through the gaps at the front and back of the bed rails. Therefore, existing hospital beds pose a risk of patients falling.

[0004] In view of the problems existing in the above-mentioned existing technology, it is necessary to research and design a new type of bed fall prevention device to overcome the problems existing in the existing technology. Utility Model Content

[0025] like Figure 1-3 As shown, this utility model provides a bed fall prevention device comprising: a base 1; a lifting support 3 is provided on the upper part of the base 1; an item placement shell 4 and a fall prevention baffle 5 are arranged side by side on the upper end of the lifting support 3; the fall prevention baffle 5 is located at the front of the item placement shell 4 and is used to block the patient on the bed; thereby increasing safety. This solves the problem of the risk of patients falling from existing beds; a pusher 6 for pushing the bed fall prevention device is fixedly provided at the rear of the item placement shell 4; and a moving part 2 for moving the bed fall prevention device is assembled at the bottom of the base 1.

[0026] The movable components include a caster wheel 21 located at the middle of the rear of the base 1, and self-locking wheels 22 on both sides of the front. The self-locking wheels 22 have a locking function. When it is necessary to fix the device in a specific position, the self-locking wheels 22 can be locked to prevent them from rotating, thereby fixing the device and preventing accidental movement.

[0027] The lifting support component 3 includes a lifting rod 31 fixedly and vertically mounted on the upper middle part of the base 1; the lifting rod 31 is either a hydraulic telescopic rod or a pneumatic telescopic rod. Both types of telescopic rods can achieve relatively smooth lifting and lowering movements, and can be selected according to actual needs, such as load capacity, response speed, cost, and other factors; the lifting rod 31 is connected to a foot-operated hydraulic pump 32 fixedly mounted on the upper part of the base 1, and the foot-operated hydraulic pump 32 is used to control the lifting and lowering of the lifting rod 31; an upper bracket 34 is mounted on the lifting end of the lifting rod 31; an item placement shell 4 is fixedly mounted on the upper part of the upper bracket 34; the lifting support component 3 also includes multiple lifting guide rods 33 evenly distributed between the base 1 and the upper bracket 34; the two ends of the lifting guide rods 33 are fixedly connected to the base 1 and the upper bracket 34 respectively, and are used to guide and limit the lifting rod 31 during the lifting and lowering process.

[0028] The fall arrestor 5 includes a limiting plate 51 fixedly mounted on the upper end of the upper bracket 34; a baffle 52 is mounted on the upper part of the limiting plate 51.

[0029] The limiting plate has a U-shaped groove elongated structure in cross section. The lifting rod 31 raises and lowers, so that the upper U-shaped groove of the limiting plate 51 abuts against the edge of the bed, thus achieving the stability of the device and the bed.

[0030] In this embodiment, the lifting rod 31 is connected to the base 1, and its lifting end is connected to the upper support 34. It adjusts the height of the limiting plate 51 by extending and retracting itself. A foot-operated hydraulic pump 32 is connected to the base 1 and controls the lifting of the lifting rod 31, providing power through foot operation. The lifting guide rod 33 is connected to the base 1 and to the limiting plate 51, limiting the movement of the limiting plate 51 during lifting to ensure its stability and prevent swaying or deviation, thus ensuring the smoothness and safety of the lifting process.

[0031] In this embodiment, the lifting rod 31 is connected to the base 1, and its lifting end participates in the connection of the upper support 34. Through its own extension and retraction, it drives the upper support 34 and the item placement shell 4 to adjust their height. The lifting guide rod 33 is connected to the base 1 and also participates in the connection of the upper support 34. During the lifting process, it limits the upper support 34 and the lifting rod 31 to ensure the smooth lifting of the limit plate 51.
