Electric field therapeutic apparatus and electrode patch thereof

Abstract

The invention provides an electric field therapeutic apparatus and an electrode patch thereof, which are configured at a corresponding position of a tumor part of a patient and comprise an electrode array for applying an alternating electric field to the tumor part of the patient, the electrode array comprises a plurality of electrode units which are arranged in at least three rows and four columns, a plurality of connecting parts which are located between the adjacent electrode units and are electrically connected with the two adjacent electrode units, and a wiring part which is arranged by laterally extending from one connecting part. And the connecting parts of the plurality of adjacent electrode units which are connected in rows have different lengths or the connecting parts of the plurality of adjacent electrode units which are connected in columns have different lengths. The electrode patch applies an alternating electric field to a tumor part of a patient through the plurality of electrode units arranged on the electrode patch so as to perform tumor treatment, so that the situation that the treatment effect is affected by insufficient electric field treatment caused by tumor size, part and position differences can be avoided, the coverage area of the electrode units is increased, and the intensity of the electric field applied to the tumor part is enhanced; the treatment effect is improved.

Description

technical field [0001] The invention relates to an electric field therapeutic instrument and an electrode patch thereof, belonging to the technical field of medical instruments. 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 treating fields (tumor treating fields, referred to as TTF) use special electric field generators to emit waves with a high rate of change and point to the corresponding tissues, and then use radiation or induction. The energy is transmitted to the corresponding parts of the human body through the insulating material, which can interfere with the mitotic process of destroying cells, and has a good effect on tumor treatment.

Problems solved by technology

Due to the difference in the body of the patient, the tumor location, tumor location, and tumor size are different. When using the existing electrode patch for treatment, there is insufficient electric field strength applied to the tumor site through the electrode patch for treatment, or the electric field does not cover part of the tumor. problems affecting the effectiveness of treatment
