Electrode patch and tumor electric field treatment system

Abstract

The invention provides an electrode patch, which is suitable for an electric field generator and comprises an electrode array for applying alternating voltage to a tumor part of a patient, a backing adhered to a corresponding part of the electrode array and a wire electrically connected with the electrode array, the electrode array comprises at least nine electrode units arranged in an array and a plurality of connecting parts located between every two adjacent electrode units, and the electrode units comprise at least one central electrode unit and a plurality of peripheral electrode units located on the periphery of the central electrode unit. The electrode array further comprises a plurality of temperature sensors selectively arranged on the corresponding peripheral electrode units. According to the electrode patch, the temperature sensors are arranged on the eight peripheral electrode units which are located in the electrode array and can generate heat easily to monitor the temperature of the portion where the electrode patch is attached, and temperature signals are fed back to the electric field generator, so that the electric field generator adjusts alternating electric signals applied to the electrode patch in time, and a human body is prevented from being scalded at low temperature.

Description

technical field [0001] The invention relates to an electrode patch and a tumor electric field treatment system, belonging to the technical field of medical devices. Background technique [0002] At present, tumor treatment methods mainly include surgery, radiotherapy, chemotherapy, etc., but there are corresponding shortcomings. For example, radiotherapy and chemotherapy will produce side effects and kill normal cells. The use of electric fields to treat tumors is also one of the frontiers of current research and development. Tumor electric field therapy is a tumor treatment method that uses an electric field generator to generate a low-intensity, medium-high frequency, and alternating electric field that interferes with the mitotic process of tumor cells. Studies have shown that electric field therapy has a significant effect in the treatment of glioblastoma, non-small cell lung cancer, malignant pleural mesothelioma and other diseases. The electric field applied by this tr...

Problems solved by technology

In order to realize timely, rapid and multi-channel transmission of the monitored temperature signal, the control circuit board of the adapter device electrically connected to the electrode patch and the control circuit board of the electric field generator need to be equipped with 40 I / O interfaces, but At present, the control circuit board of the transfer device of the existing tumor electric field therapy and the control circuit board of the electric field generating device only have 36 I / O interfaces, which cannot directly meet the requirements of the electrodes with 9 temperature sensors as disclosed in the CN112717272 patent. SMD requirements; if you need to meet the needs of more than 8 temperature sensor electrode patches, you need to increase the control circuit board of the adapter device and the I / O interface on the control circuit board of the electric field generator, and at the same time need Redesigning the control circuit board of the adapter device and the control circuit board of the electric field generator will increase the design difficulty of the adapter device and the control circuit board of the electric field generator, resulting in increased design and manufacturing costs
