Description

Adapter and electric field therapeutic instrument

Technical Field

The application relates to the technical field of medical treatment, in particular to an adapter and an electric field therapeutic apparatus.

Background

Cell proliferation is an important vital feature of organisms, cells proliferate in a dividing manner. Single cell organisms produce new individuals in a cell division manner. Multicellular organisms produce new cells in a cell division manner. In addition, cell proliferation may be mediated by human intervention, such as the use of antibiotics, either physically or chemically.

Normal cells are transformed into cancer cells by mutation of protooncogenes and cancer suppressor genes caused by oncogenes such as physical, chemical, and viral factors. Cancer cells have three characteristics of unlimited proliferation, transformation and easy metastasis, and can proliferate infinitely and destroy normal cell tissues. In addition to uncontrolled division, cancer cells can also invade locally surrounding normal tissues and metastasize to other parts of the body even via the circulatory system or lymphatic system in the body, causing new tumors to form elsewhere.

Malignant tumors have more frequent cell division than other normal tissues, and inhibition of abnormal division of cancer cells is the basis for the treatment of cancer. Based on the high sensitivity of some cancer cells to certain physical or chemical methods, irradiation and chemotherapeutics are effective means of inhibiting cancer cell proliferation in cancer therapy. However, the sensitivity of tumor cells to chemical agents is not high enough to be higher than that of most normal tissues, which results in the chemical agents damaging normal tissue cells, and bone marrow suppression, gastrointestinal toxicity and immunosuppression are typical side effects of chemotherapeutic drugs.

Current and electric field therapy have been used for many years as a physical therapy approach. There are two kinds of medical applications, the first is to apply a relatively slow rate of change of current to a human body or tissue through a conductive medium, such as a muscle stimulator, a heart defibrillator, etc., and these applications typically include a pair of conductive electrodes to cause heat to be generated in the body by passing the current through the body to stimulate, ablate, cauterize the corresponding tissue. And the other purpose is to send out waves with higher change rate to corresponding tissues through a special electric field generating device, and then conduct energy to a human body through an insulating material by using radiation or induction.

Research shows that the electric field treatment has obvious effect in treating glioblastoma, non-small cell lung cancer, malignant pleural mesothelioma and other diseases, and the electric field applied by the method can influence the aggregation of tubulin, prevent spindle body formation, inhibit mitosis process, induce cancer cell apoptosis, and meanwhile, the electric field strength and the service time become key factors in the treatment process.

The adapter for TTF (tumor TREATING FIELDS) is connected with the electrode patch and the electric field generating device through the socket and the wire harness, respectively, so that the alternating electric signal generated by the electric field generating device is finally transmitted to the electrode patch, so as to perform electric field treatment on the tissue region where the focus is located. The display screen of current adapter is connected with the casing is hard more, exists because unexpected falling or collision and leads to the cracked damage of display screen in daily use probably.

Therefore, improvements to existing adapters and electric field therapy devices are needed.
