[0048] S3: After the temperature measured by each temperature sensor in the temperature sensor array is stable, perform regional nerve block technique;

[0049] S4: Judging the effectiveness of the regional nerve block according to the change value of the skin surface temperature in the area to be measured,

[0050] If the skin surface temperature change value of the area to be measured is lower than the preset temperature change threshold, it is determined that the regional nerve bl...

Abstract

The invention provides a method for detecting a regional nerve block anesthesia effect by using a temperature sensing array. The method comprises the following steps: S1, selecting a proper temperature sensing array according to the position of a to-be-detected region, and presetting a temperature change threshold; S2, attaching the temperature sensing array to the skin surface of the to-be-detected region, and monitoring the skin surface temperature in real time; S3, after the temperature is stable, implementing a regional nerve block technology; and S4, judging the effective condition of the regional nerve block according to the temperature change value, judging that the regional nerve block does not take effect if the temperature change value is lower than the preset temperature change threshold, and judging that the regional nerve block takes effect if the temperature change value is not lower than the preset temperature change threshold. The method for detecting the regional nerve block anesthesia effect by using the temperature sensing array solves the problem that the operation is inconvenient when a thermal infrared imager is used for measuring the surface temperature field distribution of human skin at present.

Description

technical field [0001] The present invention relates to the technical field of anesthesia detection, and more specifically, to a method for detecting regional nerve block anesthesia effect by using a temperature sensing array. Background technique [0002] At present, in clinical medical applications, a series of anesthesia detection technologies have been developed to judge the effect and depth of anesthesia by detecting physiological indicators such as blood pressure, EEG, and heart rate. For example, an anesthesia depth monitoring device disclosed on March 19, 2014, with a publication number of CN103637798A, realizes anesthesia depth monitoring by collecting EEG signals. However, there is still a lack of effective means to detect the effect of regional nerve block anesthesia. At present, the range and effect of anesthesia are mainly judged by the patient’s feedback on whether there is pain in a specific part. The operation is very troublesome and will also cause discomfor...
