Abstract

The invention belongs to the field of manufacturing of medical auxiliary equipment and particularly relates to a centralized monitoring system for transfusion and main physical signs of a patient. In the system, an industrial field bus (such as CC-Link) is firstly used for realizing the centralized monitoring for the transfusion and main physical signs of the patient and a human-computer interface (touch screen) is used for performing the centralized alarm displaying (in a monitoring room), so that a hospital ward is kept quiet. The system has the advantages that the precious rescuing and treating time is striven for the patient with abnormal main physical signs, the remote monitoring service is supplied to the ending transfusion, and meanwhile, the working efficiency of medical personnel is increased.

Description

A kind of patient infusion and major physiological index centralized monitoring system

Technical field

Patent of the present invention belongs to medical auxiliary equipment and makes the field, particularly relates to a kind of system that can carry out Centralized Monitoring to patient infusion and major physiological index.

Background technology

In hospital; Always see the figure that doctors and nursess are busy; And the patient overwhelming majority will someone accompany and attend to, and the patient who has maybe be unconsciously deathward, yet the people of nurse can not find in time; Certainly doctors and nursess also have a lot of patients to need to make an inspection tour, and also are difficult to guarantee find in time that in the very first time patient's is unusual; Particularly at night, the people who accompanies and attends to also needs sleep, and medical personnel are also few, and such tragedy often takes place.

Summary of the invention

To the problem of above existence, we have proposed a kind of patient infusion and major physiological index centralized monitoring system, and it can be monitored through major physiological index such as people's pulse, body temperature and transfusion are ended; Obtain real time data; Compare with normal data, reach certain limit when above, send warning automatically when compare deviation with normal value; The prompting doctor checks patient, strives for necessary rescue time.For realizing to a plurality of patient time monitoring, we have introduced the industrial field bus technology.

As shown in Figure 1, be system's basic block diagram.A PLC control is all used in each ward among the figure, to realize each patient's of this ward the major physiological index (body temperature, heart rate, electrocardio etc.) and the monitoring of transfusion end of a period; And pass through the CC-Link communication module and realize, and carry out monitoring display by man machine interface to each each patient's of ward the major physiological index and the Centralized Monitoring of transfusion end of a period.Can not only improve medical personnel's monitoring efficient like this, also can improve the timely rescue rate in the critical moment of patient.

In the present invention, man machine interface operation, demonstration, monitoring monitoring window have cryptoguard, like this, have only the people through authorizing to make amendment to monitoring parameter, have further guaranteed the reliability of system works.

In the present invention, electrocardio detects the analog module that the input of band plurality of voltages is adopted in input, after the laggard row operation of input PLC, and the machine interface display of making a gift to someone ecg curve figure.

In the present invention, end to detect principle be to utilize that the refractive index of air and medicinal liquid (mainly being water) is different judges detection in transfusion.As shown in Figure 2, for light refraction comparison diagram in the vertical plane (we have ignored the thickness of bottle and the refraction that bottle is produced in the drawings), when still having enough liquid in the bottle, the light that sends from A point passes through the refraction final directive B point of liquid, shown in Fig. 2 a; When in the bottle during fluid low, the light that sends from the A point does not pass through the refraction of liquid, thus final directive C point, shown in Fig. 2 b; When liquid level was lower than detection faces, vertical light will change direction because of the refraction that loses liquid like this.Equally, for Fig. 3 of light refraction situation in the horizontal plane, when still having enough liquid in the bottle, the light that sends from the A point is through the final directive B point of refraction of liquid, shown in Fig. 3 a; When in the bottle during fluid low, the light that sends from the A point does not pass through the refraction of liquid, thus final directive C point, shown in Fig. 3 b; That is to say that when liquid level was lower than detection faces, horizontal light also can change direction because of the refraction that loses liquid.So we have selected for use optical fiber correlation pick off to infuse and end to have detected.
