Fall bed alarm system

technical field

The utility model relates to the technical field of alarm systems, in particular to an alarm system for falling from a bed.

Background technique

In nursing institutions such as hospitals and nursing homes, there are usually escorts who provide 24-hour care for patients who need to rest in bed after surgery and elderly people who are sick and have limited mobility, so as to prevent such patients and elderly people from falling out of bed. Accidents, however, in reality, in some cases, the accompanying staff will temporarily leave for some reason. If such patients and the elderly fall from the bed at this time, there will be a great safety hazard, because once they fall from the hospital bed, they will often die. Fainting and paralysis, and the failure of the accompanying staff to detect and provide corresponding care at that time will likely lead to the loss of life of such patients and elderly people.

Utility model content

The technical problem to be solved by the utility model is to provide a bed fall alarm system, which automatically monitors whether the patient falls from the bed through the gravity monitoring device and the controller, and sends out an alarm signal by the alarm device after the patient falls from the bed, thereby effectively solving the problem. The problem that can not be discovered in time when the patient falls off the bed.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: including a controller, an alarm and four positioning seats, one side of the positioning seats is provided with a slope surface, and the slope surface extends from the bottom of the positioning seat to the top , the top of the positioning seat is also provided with a groove that can accommodate the universal wheel at the foot of the bed, the bottom of the groove is provided with a gravity monitoring device, and the positioning seat is also provided with a plurality of Lugs fixed on the ground, the gravity monitoring device and the alarm are electrically connected to the controller, and when the pressure value received by the gravity monitoring device is lower than the preset value of the controller, the controller controls the alarm to send out Alarm.

Further, the gravity monitoring device is a load cell, and when the pressure on the load cell is lower than the preset value of the controller, the controller controls the alarm to send an alarm signal.

Alternatively, the gravity monitoring device includes a bearing platform, an adjustable damper and a touch switch, the adjustable damper is fixedly connected to the bottom of the groove, and the bearing platform is connected to the top of the adjustable damper and can be placed in the groove. The touch switch is set under the load-bearing platform and is electrically connected to the controller. When the pressure on the load-bearing platform is lower than the preset value of the controller, the load-bearing platform moves upward to make the corresponding touch switch The switch is turned off, and when all the touch switches are turned off, the controller controls the alarm to send out an alarm signal.
