Technical Field
[0001] This utility model belongs to the technical field of anti-fall bed devices for internal medicine, and particularly relates to an anti-fall bed device for internal medicine patients. Background Technology
[0002] Falling from bed is one of the main safety risks for bedridden patients in hospitals and a major risk of injury within hospitals. A hospital bed fall incident refers to an accidental fall from the bed to the floor that is beyond the patient's control during hospitalization. Bed falls not only cause physical and psychological suffering for patients but also increase the financial burden on families, become a potential source of medical disputes, and reduce patient satisfaction. Preventing falls / bed falls by hospitalized patients is a major clinical challenge. To address this, we have designed a bed fall prevention device for internal medicine patients that is safe, convenient, and effective. Utility Model Content

[0022] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an anti-fall bed device for internal medicine patients.
[0023] like Figure 1-3As shown, the present invention provides a fall prevention bed device for internal medicine patients, including a bed frame 1. Load sensors 8 are provided at the four corners and the middle of both sides of the upper surface of the bed frame 1. A bed board 2 is provided on the upper surface of the six load sensors 8. Multiple evenly and orderly distributed support springs 7 are provided between the bottom of the bed board 2 and the upper surface of the bed frame 1. The support springs 7 provide good support for the bed board 2. The upper surfaces of both sides of the bed frame 1 are equipped with guardrails 5, and a detachable protective frame 6 is installed between the two guardrails 5. The protective frame 6 includes two oppositely distributed connecting plates 12, and multiple equally spaced guardrails 13 are installed between the two connecting plates 12. The upper surface of the guardrail 5 is provided with multiple arc-shaped openings 11 that correspond one-to-one with the guardrails 13. The diameter of the arc-shaped openings 11 matches the diameter of the guardrails 13, and the inner sidewall of the connecting plate 12 contacts the outer sidewall of the guardrail 5. In use, both ends of the guardrails 13 are inserted into the arc-shaped openings 11 of the two guardrails 5, so that the protective frame 6 is above the bed board 2. When the patient lies on the bed board 2, the protective frame 6 will be above the patient, thus providing a good protective effect. When the patient rolls over to the edge of the bed board 2 and is about to fall off the bed, the guardrails 13 will block the patient, effectively preventing the patient from falling off the bed. It is highly practical.
[0024] One of the guardrails 5 has three equally spaced infrared emitting modules 9 arranged along its length on its side wall, and the other guardrail 5 has infrared receiving modules 10 arranged corresponding to the three infrared emitting modules 9 on its side wall. A data acquisition and processing system 3 is installed at the top of the headboard of the bed frame 1, and an audible and visual alarm 4 is installed at the top of the data acquisition and processing system 3. The data acquisition and processing system 3 includes a data acquisition module and an embedded microcontroller. When the patient moves to the edge of the bed board 2, it will exert pressure on the load sensor 8. The data acquisition and processing system 3 receives the signal and triggers the audible and visual alarm 4, thus alerting medical staff and caregivers to take timely action. When the patient rolls over the guardrail 5, it will obstruct the infrared emitting modules 9 and the infrared receiving modules 10, causing a change in the strength of the electrical signal output from the receiving end. At this time, the audible and visual alarm 4 will activate, alerting medical staff and caregivers to take timely action. To prevent false alarms caused by the patient accidentally blocking the infrared pulses when stretching their arms and legs, a delay trigger can be set. For example, an alarm will not be triggered if the signal is blocked for less than 2 seconds (equivalent to a brief moment when a hand or foot blocks the light); an alarm signal will only be issued if the blocking time is greater than 2 seconds.
[0025] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
