More specifically, as shown in fig. 3, in this embodiment, the physiological information collecting module 140 specifically includes: the heart rate monitoring device comprises a heart rate acquisition unit 141, a blood oxygen acquisition unit 142, a body temperature acquisition unit 143, a dynamic blood pressure acquisition unit 144, a breath acquisition unit 145 and a physiological parameter alarm unit 146, wherein the heart rate acquisition unit 141 is connected with the control module 110 and acquires a heart rate value of a patient under the control of the control module 110; a blood oxygen collecting unit 142 connected to the control module 110, for collecting the blood oxygen value of the patient under the control of the control module 110; the body temperature acquisition unit 143 is connected with the control module 110 and acquires the body temperature value of the patient under the control of the control module 110; a dynamic blood pressure collecting unit 144 connected to the control module 110, for collecting the dynamic blood pressure value of the patient under the control of the control module 110; a breath collection unit 145 connected to the control module 110, for collecting a breath frequency value of the patient under the control of the control module 110; of course, in addition, the physiological information collection module 140 can also collect the bed number of the patient, so that the medical staff can process the alarm signal more quickly, and thus, various physiological values of the patient can be collected in real time. In an embodiment, the above-mentioned acquisition unit is in the form of various sensors corresponding to the acquisition unit, for example, the heart rate acquisition unit 141 is actually a heart rate sensor for acquiring a heart rate value of the patient, and so on.
A physiological parameter alarm unit 146, which is respectively connected to the control module 110, the fluid path switch unit 132, the heart Rate acquisition unit 141, the blood collection unit 142, and the oxygen collection unit 142, specifically, in this embodiment, a Heart Rate Variability (HRV) with clinical significance is used as an evaluation index of the physiological parameter alarm unit 146, before work, first, a corresponding preset RR interval mean standard deviation SDNN value and a root mean square rmsd value of a preset adjacent RR interval difference value are set in the physiological parameter alarm unit 146, after infusion is performed on a patient, a processor (such as a single chip microcomputer) inside the physiological parameter alarm unit 146 starts to calculate a root mean square rmsd of an RR interval mean standard deviation SDNN and an adjacent RR interval difference value according to a heart Rate value collected by the heart Rate acquisition unit 141 or a blood oxygen value collected by the blood oxygen collection unit 142, and if the obtained RR interval mean standard deviation SDNN exceeds the preset RR interval mean standard deviation sdrr value or the obtained adjacent RR interval mean square rmsd value If the root mean square rmsd of the interval difference exceeds the range of the root mean square rmsd of the preset adjacent RR interval difference, the control module 110 controls the motor to reversely clamp the infusion pipeline, as shown in fig. 6, that is, controls the fluid circuit switch unit 132 to close the infusion switch to stop infusion, and simultaneously controls the physiological parameter alarm unit 146 to send out a physiological response alarm signal and give an alarm to notify medical personnel to check the physiological response, and if necessary, starts an emergency plan to rescue the patient; if the obtained standard deviation SDNN of the RR interval mean does not exceed the preset standard deviation SDNN of the RR interval mean, and the obtained root mean square rmsd of the adjacent RR interval difference does not exceed the range of the root mean square rmsd of the preset adjacent RR interval difference, the comparison is ended, and an instruction is sent to the heart rate acquisition unit 141 to acquire the heart rate value again or the blood oxygen value is acquired again by the blood oxygen acquisition unit 142. Finally, it should be noted that the setting of the preset RR interval mean standard deviation SDNN value and the root mean square rmsd value of the preset adjacent RR interval difference is based on the related value under the normal condition of the patient, that is, the related index of the patient is collected before the patient performs infusion to obtain the related preset value (the preset RR interval mean standard deviation SDNN value and the root mean square rmsd value of the preset adjacent RR interval difference), it can be seen that different patient setting values are different, so that the patient performs system comparison during infusion between the patient infusion period value and the self normal condition value, rather than the patient infusion period value (the SDNN value and the rmsd value) and a reference value (an empirical value) unrelated to the patient, thereby greatly improving the accuracy of the system.
In particular, HRV refers to the small difference between successive cardiac beat intervals, which results from the modulation of the sinus node of the heart by the autonomic nervous system, such that there are typically tens of milliseconds of difference and fluctuations in cardiac beat intervals. Clinically, HRV is used for judging the condition of cardiovascular diseases, preventing cardiovascular diseases and predicting sudden cardiac death and arrhythmia events. The HRV evaluation indexes include a time domain index, a frequency domain index and a non-linear index, and in this embodiment, the standard deviation SDNN of the normal RR interval of the time domain index and the root mean square rmsd of the difference value between adjacent RR intervals are selected as evaluation criteria. The physiological parameter alarm unit 146 obtains a heart rate value acquired by the heart rate acquisition unit 141 (heart rate sensor) or a blood oxygen value (heart rate waveform) acquired by the blood oxygen acquisition unit 142 (blood oxygen sensor), further obtains an R-wave position by using low-pass filtering and a difference threshold algorithm, calculates an RR interval, and obtains an RR interval MEAN value (MEAN) by using the following formula:
wherein N is the total heart rate RR monitored in a preset time periodiIs the ith RR interval.
SDNN values are standard deviations of normal RR intervals, with HRV moderate decreases clinically when SDNN <100 ms; when the SDNN <50ms shows that HRV is obviously reduced, the fatality rate of patients is greatly increased, and the standard deviation SDNN of RR intervals is calculated according to the standard by using the following formula:
wherein N is preTotal heart beat, RR monitored in a set period of timeiIs the ith RR interval. RR is the mean RR interval of N heart beats.
The rMSSD value is the root mean square of the difference value of adjacent RR intervals, is used for calculating the variation of adjacent cardiac cycles and reflecting the rapid change of HRV,
wherein N is the total heart rate RR monitored in a preset time periodiFor the ith RR interval, RRi-1And calculating the standard deviation SDNN value of the RR intervals and the root mean square rMSSD value of the difference value of the adjacent RR intervals for the i-1 RR intervals so as to judge whether the patient has transfusion reaction, and sending a primary alarm if the patient has transfusion reaction.
