Fall prevent alarm

       Report on Prevention and Intervention of Falls During Sudden Nighttime Awakening in        Disabled/Dementia-Induced Elderly

I. Pain Points

Many disabled or dementia-inducing elderly people get up suddenly at night, completely unaware of the dangers. With no one around to help them, and the room dark, a single stumble could lead to a fall from which they may never get up again. Even more worrying is the risk of them getting lost—they might push open the door and go out, only to find them gone at dawn.

The root of the problem lies in two aspects: one is **blind spots in caregiving**, and the other is **insufficient reaction time**.

From the Elderly's Perspective:** At night, their consciousness is already blurred, and their legs are not agile. Walking in the dark relies entirely on sense of touch, making falls almost inevitable.

From the Caregiver's Perspective:** Many of those caring for the elderly are their children, who are also aging themselves. People need to sleep, and it's impossible to keep a constant watch all night. Sleeping with your breath hanging in the balance is restless; not watching is also frightening. This constant state of tension is physically and psychologically unsustainable.

 II. Scenarios

The most common dangerous situations occur in the early hours of the morning.

Family members or caregivers have just fallen into a deep sleep when the elderly person suddenly wakes up, needs to use the restroom, or simply can't sleep and wants to get up and walk around. Elderly people with dementia often won't call for help; they'll simply try to move on their own. The bedroom lights are off, and the surrounding furniture and floor are dark, yet they're already moving their bodies.

The most dangerous part is this brief window of time.**

From the moment the elderly person's bottom leaves the bed until the movement finally wakes the family, the time in between is very short, but it's precisely in this brief moment that most falls occur—some result in fractures, some in head injuries, and some are not discovered for a long time after falling.

III. Data

The core technical specifications of the Anechoease bed-exit alarm are as follows:

Parameter Item | Specification |

|Response Speed | Millisecond-level triggering, virtually no delay |

| Pressure Sensing Pad Size| 10×30 inches (approximately 25.4×76.2 cm), covering the core foothold area for elderly people when standing |

| Alarm Volume| 85dB～120dB, supports adjustable levels |

| Ease of Use| Plug and play, no app installation, no internet connection required, setup completed within 60 seconds |

| Battery Life| Built-in 3.7V lithium battery, Type-C charging, eliminating the risk of missed alarms due to dry cell batteries running out of power |

 IV. Solution

Regarding the scenarios mentioned above, the Anechoease's approach is straightforward—**instead of waiting for a fall to occur, it triggers an alarm the moment the elderly person is about to get up**.

**Physical Sensing, No Network Required**

The pressure-sensitive mat is placed directly under the bed sheet. When the elderly person lies down, the pressure creates pressure, and the device responds immediately once their back or hips are completely off the mat. The entire process doesn't involve any network connection; the signal triggers directly, providing results in milliseconds—incredibly fast.

**Sound Alarm, Dual Protection**The alarm has a dual function: firstly, it immediately wakes up family members or caregivers in the same room; secondly, the sound itself has a deterrent effect on elderly people with dementia. Many people instinctively stop upon hearing the alarm and wait for someone to come, rather than trying to walk away. Feedback in actual use has been quite positive.

**No Cameras, No Privacy Concerns**

Many families are hesitant about surveillance cameras, feeling they are disrespectful to the elderly. This device completely avoids this problem. The pressure-sensitive pad is hidden under the sheet, and the main unit is placed beside the bed. The elderly person won't even feel its presence, and will feel no psychological burden using it.
