Embodiment Construction

[0044] In order to better understand the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0045] Figure 5 is a schematic diagram of the monitoring system block diagram. The client of the monitoring system is composed of three physiological parameter detection modules, namely the 630A non-invasive blood pressure module, the 811 ECG / respiration / body temperature module, and the 9003 blood oxygen module. Online and continuous detection of physiological parameters such as ECG, respiration, body temperature, and blood oxygen; three monitoring modules build a client monitoring system through the PC104 bus system, and the client and the community remote monitoring system are connected through the network interface on the PC104 bus .

[0046] Figure 6 is a schematic diagram of the client of the monitoring system. The new intelligent physiological parameter monitor detects the physiological parameters of the monitored ob...

Abstract

The invention discloses an intelligent alarming method of monitor system, which is characterized by the following: stepping the FPE model of final predict error algorithm; basing on recursive least square method RFE with forgetting factor to update the physiological parameter time sequence model dynamically; establishing the fitful alarming model according to different monitor object; setting the alarming threshold value automatically; adjusting the model parameter automatically to approach the optimum value; tracing the 'slow' physiological parameter time sequence; affirming the accuracy of model. The invention is fit for central monitor system, myasthenia monitor ward and coronary disease myasthenia monitor ward in the hospital, which can be used in the community remote monitor system.

Description

Technical field [0001] The invention belongs to the field of biomedical signal processing, and particularly relates to an intelligent monitoring system alarm method. Background technique [0002] The existing monitoring system mainly adopts the following two alarm methods: an alarm method based on preset thresholds and an intelligent alarm method based on timing modeling proposed by M.Imboff et al. There are certain problems in the use of these two methods. [0003] The alarm method based on preset thresholds means that the monitoring system sets the upper and lower limits for the monitored vital sign parameters (for example, the preset upper limit is 120 and the lower limit is 50 for the heart rate parameter. When the monitoring value exceeds this range, That is, the alarm information is issued). This alarm method has disadvantages such as increasing the complexity of the system operation, prone to false alarm information, and unable to reflect the changes in the physical condit...
