the bed leaving judging submodule 312 is configured to obtain data of the pre-judging submodule 311 and the four weight sensors 22, and when the bed leaving judging submodule 312 obtains pre-alarm data of the pre-judging submodule 311 and the sum of the values of the four weight sensors 22 decreases suddenly, the bed leaving judging submodule 312 generates alarm data, and the reminding module 32 sends out an alarm signal according to the alarm data of the bed leaving judging submodule 312.

Because the patient who is inconvenient to move often gets up to a bed with large movement due to the inflexible leg relation, the invention can analyze the data of the four weight sensors 22 under the action of the pre-judging submodule 311, when the values of the weight sensors 22 fluctuate respectively, the action that the patient sits on the bed body in a changed state when lying on the bed body is proved, when the values of the two weight sensors 22 on one side of the bed body 1 suddenly change, the pressure on one side of the bed body 11 suddenly increases, the pressure on the other side suddenly decreases, the patient sits on the bed body 11 and is proved to sit at the bed side, the pre-judging submodule 311 can judge whether the patient has the tendency of getting out of the bed according to the change of the weight sensors 22, so that medical personnel can timely process the patient with the tendency of getting out of the bed through the reminding module 32 to prevent accidents. When the sum of the values of the four weight sensors 22 is suddenly decreased, it is proved that the patient leaves the bed body 1, and the medical staff can rapidly respond through the reminding module 32 to ensure the safety of the patient leaving the bed.

Preferably, the pre-decision sub-module 22 is capable of setting different threshold levels depending on the weight of the patient.

The measurement value of the weight sensor 22 fluctuates when the patient lies and the measurement value of the weight sensor 22 fluctuates when the patient turns over, but the measurement value of the weight sensor 22 fluctuates when the patient lies and changes more than the measurement value of the weight sensor 22 fluctuates when the patient turns over. Since the weights of different patients are different, the fluctuation of the measured value of the weight sensor 22 is different when the patient lies and changes, and the fluctuation of the measured value of the weight sensor 22 is also different when the patient turns over, when the fluctuation of the measured value of the weight sensor 22 is equal to the fluctuation of the measured value of the weight sensor 22 when the patient with heavier weight lies and changes, the pre-judgment sub-module 311 will generate false alarm.

Preferably, the reminding module 32 can also display different colors for the corresponding bed body 1 states according to the pre-alarm data and the alarm data sent by the pre-judgment sub-module 311 and the bed leaving judgment sub-module 312, and the reminding module 32 can also be connected with the smart phone through a D L NA protocol, so that the smart phone can receive the data of the reminding module 32.

In this embodiment, remind module 32 including installing the display in the nurse station, the picture and the digital sign of each bed body 1 can be shown to the display, the display can acquire in advance judgement submodule 311, from the data of bed judgement submodule 312 to the realization shows with different colours in the bed body 1 that corresponds in the display according to advance warning data and alarm data, thereby be convenient for medical personnel to know whether patient appears from the bed condition.

And moreover, by using the D L NA protocol, the smart phone of the medical staff connected to the same network can acquire the pre-alarm signal and the alarm signal of the reminding module 32, so that the patient leaving the bed can be processed in time.

The monitoring platform further comprises a weight measuring module 33, the weight measuring module 33 is used for acquiring data of the weight sensors 22, the weight measuring module 33 can calculate the sum of measured values of the four weight sensors 22, and the weight information of the patient can be acquired by subtracting the bed body 1 and the weight values of bedding on the bed body 1.

Because the weight condition of the patient needs to be considered when the doctor prescribes the medicine, the weight measurement of the patient with inconvenient action is troublesome, in the embodiment, the weight data of the patient can be directly obtained through the weight measurement module 33, so that the doctor prescribes the medicine conveniently.

Preferably, the bedding weight value on the bed body 1 is preset with three grade values so as to select a proper bedding weight grade value according to the bedding thickness on the bed body 1. Because the bedding weight specification of the hospital is relatively uniform, the bedding weight is quickly obtained under the action of the preset three grade values, so that the weight measuring module 33 can quickly measure the bedding weight.

The hospital bed for monitoring the patient with mobility inconvenience of the embodiment comprises the following steps:

s1, at night, the medical staff controls the bed body 1 of the patient with mobility disability, through the trigger button, the controller 20 controls the electromagnet 52 to be powered on immediately, after the delay time set by the single chip microcomputer, the controller 20 controls the electric telescopic rod 62 to extend until the supporting plate 2 touches the travel switch 12, the controller 20 controls the electromagnet 52 to be powered off according to the signal of the travel switch 12, after the delay time set by the single chip microcomputer, the controller 20 controls the electric telescopic rod 62 to stop, and the stress support of the supporting rod 21 is realized.

S2, the appropriate threshold level is determined in the pre-decision sub-module 311 based on the weight of the patient. When the patient lies on the bed and changes to sit on the bed, the values of the four weight sensors 22 fluctuate respectively; then when the patient sits at the edge of the bed body 1 and wears shoes, the pressure on one side of the bed body 11 is suddenly increased, and the pressure on the other side is suddenly reduced, so that the numerical values of the two weight sensors 22 on one side of the bed body 1 are suddenly changed, the pre-judgment submodule 311 judges that the patient has the tendency of leaving the bed, and sends pre-alarm data to the reminding module 32, and medical personnel obtain a pre-alarm signal through the reminding module 32, so that the medical personnel can timely know the condition of the ward.

S3, when the patient leaves the bed body 1, the pressure felt by the four weight sensors 22 is reduced, so that the sum of the numerical values of the four weight sensors 22 is reduced suddenly, the bed-leaving judgment submodule 312 judges that the patient leaves the bed, and sends alarm data to the reminding module 32, and the medical staff obtains an alarm signal through the reminding module 32, so that the medical staff can go to the ward quickly to know the situation.
