Referring to fig. 1 and 2, fig. 1 is a schematic front view of a mattress according to an embodiment of the present invention, and fig. 2 is a schematic back view of the mattress according to an embodiment of the present invention.

The embodiment provides a monitoring device for leaving a bed of a patient, and belongs to the technical field of medical instruments. Referring to fig. 1 and 2, the monitoring device for the patient getting out of the bed (hereinafter referred to as monitoring device) of the present embodiment includes a plurality of pressure sensors 20, a main controller and a first alarm, wherein the main controller includes a control input end and a first control output end, the plurality of pressure sensors 20 are installed on the bottom surface 12 of the mattress 10 in series or in parallel, the patient lies on the upper surface 11 of the mattress 10, the plurality of pressure sensors 20 are connected with the control input end, the first alarm is connected with the first control output end, and the main controller can control the alarm operation of the first alarm.

The monitoring device is used for monitoring a patient with special symptoms who leaves a bed without permission, such as a patient with a leg injury, pressure values of a specified patient on a mattress are obtained through the pressure sensor 20, firstly, the main controller stores pressure range values of the specified patient when the specified patient lies and sits, the pressure sensor 20 senses the pressure values of the specified patient on the mattress in different states during the working process of the monitoring device, an analog signal is output, the analog signal is converted into a digital signal through connecting the AD converter and is transmitted to the main controller, the main controller compares the stored signal values, whether the specified patient lies on the bed, sits on the bed or leaves the bed is judged according to the comparison result, and when the specified patient is judged to sit on the bed, the main controller controls the first alarm to perform alarm work, informing medical staff to arrive in time, so as to avoid the falling of the patient caused by the possible leaving of the bed, thereby achieving the technical effect of protecting the patient.

More specifically, referring to fig. 1 and 2, the patient includes three regions in the mattress 10, the front surface 11 includes a lying region 11-1 and seating regions 11-2 on both sides of the lying region 11-1, correspondingly, the bottom surface 12 includes a lying region 12-1 and seating regions 12-2 on both sides of the lying region 12-1, and a plurality of pressure sensors 20 are distributed over the entire bottom surface 12, that is, any pressure of the patient on the mattress 10 can be known by the pressure sensors 20.

Referring to fig. 2, the plurality of pressure sensors 20 are installed on the bottom surface 12 of the mattress 10 at equal intervals, so that the pressure value of the patient on the mattress 10 can be accurately known, and the pressure values are relatively balanced.

Furthermore, the monitoring device further comprises a second alarm, the main controller further comprises a second control output end, the second alarm is connected with the second control output end, the main controller controls the first alarm to alarm, and then can control the alarm of the second alarm, namely the alarm of the second alarm is executed after the first alarm is subjected to alarm, the first alarm and the second alarm are alarms with different danger levels, and the danger level of the first alarm is lower than that of the second alarm.
