Abstract

The present invention discloses an electrode falling detection circuit. The electrode falling detection circuit comprises an impedance detection unit and a processor; the impedance detection unit is connected with electrodes and used for receiving impedance detection signals, also uses the impedance detection signals to detect electrode-loaded impedance and generates impedance signals; and the processor is connected with the impedance detection unit and used for providing the impedance detection signals for the impedance detection unit, calculates an impedance value according to the impedancesignals generated by the impedance detection unit and judges whether the electrodes fall off from a human body or not according to the impedance value. By detecting the electrode-loaded impedance value, if the impedance value is larger than a threshold value, the electrodes are considered to fall off from the human body and detection of falling-off of the electrodes from the human body is achieved.

Description

technical field [0001] The invention relates to an electrode drop detection circuit and a detection method. Background technique [0002] The medical electrodes connected to the human body may be unstable or even fall off due to the way the doctor uses them and the electrode itself is not firmly connected, which will lead to untrue physiological data collected by the device. Therefore, a corresponding device is needed to monitor in real time whether the electrode falls off from the human body. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an electrode shedding detection circuit and detection method. By detecting the impedance value of the electrode load, it is judged whether the electrode is detached from the human body, and the detection of the detachment of the electrode from the human body is realized. [0004] The purpose of the present invention is achieved by the following techni...
