[0002] Nursing bed is common in hospital and nursing agency, mainly carries out life characteristic monitoring to patient, and common monitoring mode has many kinds, sets up monitor on sickbed and is used for monitoring heartbeat and brain wave, like this needs to paste monitoring end on patient's body, like this can cause patient inconvenience, and nursing cost will increase accordingly, and this sickbed is difficult to popularize to household. UTILITY MODEL CONTENTS

[0003] To solve the above technical problem, the utility model provides a nursing bed with vital sign monitoring.

[0004] The utility model discloses a nursing bed with vital sign monitoring, which comprises a base and a bed body arranged on the base, and further comprises:

[0005] The bed plates are arranged at equal distances on the bed body, the bed plates are provided with a convex part at a middle position and inclined parts on both sides of the convex part, and a sensor part for monitoring patient activity is arranged between the convex part and the inclined parts.

[0006] The specific detection principle is to detect the activity of the patient on the sickbed. Unlike the traditional method, the traditional method requires a detector to be attached to the heart and brain to sense the electric wave and make detection activity. However, by detecting the activity of the patient, it is easier to be popularized, and it can be used in household, nursing homes, nursing agencies and hospitals, and the cost is lower.

[0007] The patient squeezes the convex part and the inclined part. When the patient is active, the weight of the patient causes the convex part and the inclined part to be squeezed into the position of the sensing part, and the internal sensor is in an on state. When all the sensors are contacted by irregular air pressure, there will be intermittent detection. The collected intermittent monitoring signals indicate that the human body is in an active state.

[0038] The number of the bed plates 6 is multiple, and the multiple bed plates 6 are connected through the spun cloth.

[0039] The bed plate 6 comprises a frame plate 7, a soft pad 8 is sleeved in the frame plate 7, and the top of the soft pad 8 is located above the frame plate 7. A small square groove is symmetrically arranged at the middle position of the top of the soft pad 8, and a mounting groove 9 is arranged outside the small square groove.

[0053] Time window Signal pattern Possible state Short time interval (e.g. 5-10 seconds) Signal fluctuation (1 / 0 alternation) Normal activity Medium time interval (e.g. 10-30 minutes) Continuous stable signal (1) Rest or sleep Long time interval (e.g. >30-60 minutes) Continuous stable signal (1) without significant fluctuation Possible abnormality, such as deep sleep or coma Ultra-long time (e.g. >2-6 hours) Signal continuously stable (1) without any fluctuation Alarm required, possible accident (e.g. death)

[0054] The specific judgment method adopts a sliding window detection method; using the sliding window method, the sensor signal mode is counted every certain time, such as 10 seconds: set the window size T_w, such as 10 seconds, 30 seconds, 1 hour, etc.

[0055] Calculate the change rate R of the signal in the window: R = \frac{\text{signal change times}}{\text{window length T_w}}

[0056] If R> threshold, it is determined to be an active state;

[0057] If R is approximately 0, it is determined to be a stationary state;

[0058] If R is approximately 0 for a long time, trigger the alarm.

[0059] Abnormality detection; calculate the change trend of multiple windows, if there is no fluctuation for a long time, such as 2 hours, a danger signal is triggered. Set the upper limit of the continuous stable signal, and alarm if it exceeds a certain threshold, such as 6 hours.

[0060] The above is only a preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
