Problems solved by technology

[0004] However, the existing TENS devices still have many disadvantages: 1) The device is too large for the patient to carry; 2) The adjustment of the stimulation intensity depends on the patient itself, which increases the burden on the patient; 3) The adjustment of the stimulation intensity is not intelligent enough , some painful parts are difficult for patients to touch, which increases the difficulty of adjustment
4) Electrode patches need to be replaced frequently, which increases the cost of use

Embodiment 1

[0065] like figure 1 Shown, for a kind of automatic intensity-adjusting pain relief nerve stimulation system of the present invention, comprising:

[0066] 2 stimulating microelectrodes 5 to stimulate the subcutaneous nerve of the human body to alleviate the pain of the injured;

[0067] The stimulation intensity sensor 3 is connected with the stimulation microelectrode 5 to obtain the current signal thereon;

[0068] The stimulating electrode driving circuit 2 is connected with the stimulating microelectrode 5, and delivers stimulating current to the stimulating microelectrode 5 to drive its work;

[0069] The information collection and processing chip 1 is connected with the stimulation intensity sensor 3 and the stimulation electrode drive circuit 2, acquires the signal of the stimulation intensity sensor 3, and sends a signal to the stimulation electrode drive circuit 2 according to preset settings, so that its output corresponds to Intensity of the stimulation current, ...

Embodiment 2

[0072] On the basis of the analgesic nerve stimulation system with automatic intensity adjustment described in Embodiment 1, the information collection and processing chip 1 preferably includes:

[0073] Stimulation signal acquisition and processing module 16, used for collecting the signal of the stimulation intensity sensor 3 and performing conversion processing;

[0074] The wireless charging module 11 is used to wirelessly charge the coil 4, the wireless charging is more convenient and convenient, and the setting of related external interfaces can be reduced, so that the system can be set more concentrated and compact;

[0075] The communication module 12 is used to communicate with external devices. The communication module 12 described in this embodiment preferably uses a low-power Bluetooth device to reduce energy consumption, and the user can easily log on to the external device through the mobile phone to understand the system usage. It can also be adjusted, but it is...

Embodiment 3

[0082] A method for stimulating the analgesic nerve stimulation system described in embodiment 1 or 2, its flow chart is as follows figure 2 shown, including the following steps:

[0083] (1) Start the whole system through the information collection and processing chip 1, preferably set the startup function on the touch sensing module 13, and start the lowest voltage stimulation mode, its schematic diagram is as follows image 3 As shown, since there is no stimulation mode selection at the beginning, it is necessary to start the lowest voltage stimulation mode immediately when starting up to protect the safety of patients in order to prevent the power-on current from being too large, or some sudden currents causing the user to be injured by electricity;

[0084] (2) By selecting the preset stimulation mode on the information collection and processing chip 1, the preset stimulation mode can set different stimulation intensities according to the level of pain that needs to be r...

Abstract

The invention discloses a pain relieving nerve stimulation system and a nerve stimulation device capable of automatically adjusting intensity and a patch device. The pain relieving nerve stimulation system comprises a plurality of stimulation micro-electrodes, a stimulation intensity sensor, a stimulation electrode driving circuit, an information acquisition processing chip and a coil, wherein the stimulation micro-electrodes are used for conducting point stimulation on human subcutaneous nerves; the stimulation intensity sensor is connected to the stimulation micro-electrodes and is used for acquiring signals of the stimulation micro-electrodes; the stimulation electrode driving circuit is connected to the stimulation micro-electrodes and is used for transmitting stimulation current to the stimulation micro-electrodes so as to drive the stimulation micro-electrodes to work; the information acquisition processing chip is connected to the stimulation intensity sensor and the stimulation electrode driving circuit, and the information acquisition processing chip is used for acquiring signals of the stimulation intensity sensor and is used for transmitting the signals to the stimulation electrode driving circuit in accordance with preset, so that the stimulation electrode driving circuit can output stimulation current of corresponding intensity; and the coil is connected to the information acquisition processing chip. According to the pain relieving nerve stimulation system disclosed by the invention, the stimulation current is detected by virtue of the stimulation intensity sensor, so that a function of conducting automatic adjusting is achieved, and the convenience of a patient in adjusting the stimulation intensity is greatly improved; and the pain relieving nerve stimulation system is highly integrated, the volume of the system is greatly diminished and the portability of a stimulator is enhanced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an analgesic nerve stimulation system, method and patch device with automatic intensity adjustment. Background technique [0002] Chronic pain is pain that persists for more than a month. At present, there are at least 100 million chronic pain patients in China. Electrical nerve stimulation is a treatment that uses electrical current to relieve chronic pain. It can stimulate the patient's external or spinal nerves with tiny current pulses to interfere or block the transmission of pain signals, so as to achieve short-term pain relief. [0003] Transcutaneous electrical nerve stimulation (TENS, transcutaneous electrical nerve stimulation) is a common way to relieve pain through electrical nerve stimulation therapy. Through a small device powered by a battery, it can generate a low-voltage current, and through the stimulating electrodes placed on the painful surface, transmit the ch...
