Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1-2, a falling bed alarm system includes: a bed body, on which a bed board 1 is arranged, and the falling bed alarm system also includes a pressure sensor, a controller 4 and an alarm 6, and the pressure sensor includes a uniform A plurality of first pressure sensors 2 distributed on the left and right sides of the upper surface of the bed board and a second pressure sensor 3 positioned at the center of the upper surface of the bed board, and the first and second pressure sensors are all electrically connected to the controller 4, and the controller 4 is wirelessly connected with the alarm 6, the alarm 6 is provided with a flashing light 7 and a buzzer 8, and the first and second pressure pressure sensors, the controller 4 are electrically connected with the power supply through the switch 5, and the alarm 6 is provided with storage battery; the controller 4 controls the alarm to send out different warning signals according to the pressure signals of the first and second pressure sensors.

Three first pressure sensors 2 are arranged on the left and right sides of the upper surface of the bed board 1 .

The controller 4 is arranged on the underside of the bed board, and the switch 5 is arranged on the head of the bed.

The alarm 6 is a portable alarm.

The wireless connection is WIFI or Bluetooth connection.

The working principle of the falling bed alarm system is as follows: when a child or a patient is lying down and needs to use the system, the switch 5 is turned on, and the alarm 6 is placed at the position where the nursing staff is. It can be placed in the caregiver's bedroom. Under normal circumstances, a child or a patient is located in the center of the bed board 1 , and at this moment, the pressure of the second pressure sensor 3 is relatively high, while the pressures of all the first pressure sensors 2 are relatively small or zero. What needs to be pointed out is that since the bed board 1 often has covers such as quilts, the pressure of the first pressure sensor is often not zero, but it must be much smaller than the pressure value of the second pressure sensor 3 . The controller 4 judges that the child or the patient is resting normally according to the first pressure sensor 2 and the second pressure sensor 3 at this time, and controls the alarm 6 not to send a warning signal. When the position of the child or the patient changes and moves to the edge of the bed, the pressure of the at least one first pressure sensor 2 is greatly increased. When the controller 4 detects that the pressure of any one or more first pressure sensors 2 has greatly increased or exceeded a preset value, it is judged that the child or the patient is already on the edge of the bed board, and the possibility of falling from the bed is greater or will fall from the bed , the controller 4 sends a signal to control the alarm 6 to send the first warning signal, such as the flashing light 7 flickering. At this time, the nursing staff can know that the position of the child or the patient on the bed changes in time, and help the child or the patient return to the normal resting position in time, thus avoiding the possibility of falling from the bed to a large extent.

When the controller detects that the pressures of all the first pressure sensors 2 and the second pressure sensors 3 are very small or zero, the controller judges that the child or the patient is not in bed, and the controller 4 sends a second alarm to the alarm. The warning signal, such as controlling the buzzer 8 to send an alarm sound, can wake up the nursing staff in time, and the nursing staff moves the child or the patient to the bed, preventing the child or the patient from being positioned on the ground for a long time and causing the situation to deteriorate further. And when the caregiver needs to remove the child or the patient from the bed, the switch can be turned off to close the above-mentioned falling bed alarm system to prevent false alarms.

Three first pressure sensors 2 can be arranged on the left and right sides of the upper surface of the bed board 1, and of course more can be installed; in order to facilitate the user's experience, the controller 4 can be arranged on the lower side of the bed board so that the controller does not collapse. For the user, the switch 5 is arranged at the head of the bed to facilitate the caregiver to open or close the above-mentioned falling bed alarm system. The alarm 6 is a portable alarm, so that the caregiver can carry and move the alarm conveniently. The wireless connection may be a WIFI or Bluetooth connection.

It should be pointed out that since the bed board often has covers such as quilts and quilts, the first pressure sensor 2 and the second pressure sensor 3 often have a certain pressure value even if they are not pressed by people. In order to accurately determine the position of the child or patient, a preset pressure value can be set, and the controller 4 compares the pressure values of the first pressure sensor 2 and the second pressure sensor 3 with the preset value to determine whether the first pressure sensor 2 and the second pressure sensor Whether there are children or patients in the corresponding positions of the two pressure sensors 3 .

The bed falling alarm system of the utility model can be started according to needs, and the switch is closed when the patient or child is resting at night to start the above falling bed alarm system, and the alarm can be placed in the nurse's station of the hospital or the parent's room, and the patient or child can be monitored. child care. The bed falling alarm system of the utility model can not only ensure the normal use of the bed, but also facilitate sitting on the edge of the bed and getting on and off the bed, and can judge the sleep condition of the patient or child according to the first pressure sensor and the second pressure sensor, and when the patient Or when the child is resting close to the edge of the bed, the alarm can be controlled to issue a warning to notify the nursing staff to move the patient or child to the center of the bed in time; Notify the caregiver of the accident.

The embodiments of the present utility model have been described in detail above, but the content described is only a preferred embodiment of the present utility model, and cannot be considered as limiting the implementation scope of the present utility model. All equal changes and improvements made according to the application scope of the utility model should still belong to the scope covered by the patent of the utility model.
