Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to an infrared-sensing alarm for preventing falls from a patient's bed. Background Art

[0002] Falls from bed and tumbles are a major cause of injury and death among the elderly. They severely impact their physical and mental health, placing a significant burden on families and society. Geriatrics has classified falls from bed and tumbles as a geriatric syndrome. Patients with cognitive impairment often experience behavioral and mental disorders, as well as motor impairments such as gait instability and impaired balance, further increasing their risk of falls from bed and tumbles. Currently, the number of elderly patients with cognitive impairment in hospitals, community hospitals, and nursing homes at all levels in China is increasing, and falls from bed and tumbles are a constant risk. However, current early warning systems for falls from bed and tumbles are inadequate, making falls and tumbles highly likely to occur when family members and caregivers are away from patients, resulting in injuries ranging from minor skin abrasions and soft tissue injuries to severe fractures, spinal cord injuries, or internal bleeding. If the patient lands on their head, brain damage can be life-threatening. These consequences directly impact the patient's health and ability to care for themselves, increasing the burden on their families and society. Furthermore, the time it takes to provide emergency treatment after a fall from bed is crucial; the earlier the emergency, the better the patient's subsequent recovery.

[0003] Therefore, there is an urgent need for an alarm based on infrared sensing to prevent falls and out of bed, so as to improve the technical problems existing in the above-mentioned prior art. Summary of the Invention

The two, when used together, can capture images of both the bed and the area below. In particular, the infrared tracking monitor is connected to a telescopic rod, which can be adjusted to different heights, allowing the infrared tracking monitor to monitor the entire area above the bed.

[0036] The signal receiver then receives the image data collected by the information acquisition module and transmits it to the processor. The processor analyzes the collected image data and the patient's posture in bed to determine whether the patient's real-time posture poses a risk of falling out of bed. The signal transmitter then sends corresponding instructions to the controller.
