Embodiment Construction

[0050] As described in the Background Art, using figure 1 The closed-loop pain suppression system shown has low accuracy in collecting pain signals, and useful pain signals are easily lost. Through research, it is found that there are large differences in the amplitude and frequency of pain signals between different treatment individuals, and there are also large differences in the amplitude and frequency of pain signals in different parts of the same treatment individual. However, figure 1 The frequency acquisition range of the closed-loop pain suppression system shown is fixed, and the same system can only receive pain signals in a fixed frequency range, so the accuracy of pain signal acquisition is low, and useful pain signals are easily lost. The technical solution of the present invention provides an action potential recorder and a closed-loop pain suppression system. By setting a frequency selection circuit in the action potential recorder, the useful pain signal can be...

Abstract

The invention discloses an action potential recorder and a closed-loop pain suppression system. The action potential recorder comprises a first amplifying circuit, a frequency selection circuit, an analog to digital conversion circuit, a first control circuit and a first wireless receiving and transmitting circuit, wherein the first amplifying circuit is suitable for carrying out amplification treatment on a pain signal to obtain an amplified signal; the frequency selection circuit is suitable for carrying out frequency selection treatment on the amplified signal to obtain a frequency-selected signal; the analog to digital conversion circuit is suitable for carrying out analog to digital conversion treatment on the frequency-selected signal to obtain a digital sampled signal; the first control circuit is suitable for carrying out communication with the first wireless receiving and transmitting circuit; the first wireless receiving and transmitting circuit is suitable for carrying out communication with a master control instrument. According to the action potential recorder and the closed-loop pain suppression system, which are provided by the invention, by arranging the frequency selection circuit, the accuracy that the action potential recorder collects the pain signal is improved, and the useful pain signal cannot be lost.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an action potential recorder and a closed-loop pain suppression system. Background technique [0002] Chronic pain has always been considered a serious public health problem, which seriously affects the quality of life of patients. Prolonged chronic pain can lead to elevated blood pressure and blood sugar, decreased digestion and blood circulation. Not only that, but it can also lead to various psychological problems in patients, such as fear, depression, autism, anxiety, insomnia, and even suicidal tendencies. Statistical studies from North America, Western Europe, New Zealand, and Australia show that chronic pain is one of the most common conditions afflicting adults. Chemical methods are often used to treat chronic pain, but most chronic pain patients are not adequately rescued and treated due to financial problems or side effects. [0003] Nerve stimulation has bee...
