Problems solved by technology

"Although this invention can solve the defects such as uneven heating of tumor parts, easy damage to normal tissues, and limited heating parts and tissues existing in existing tumor hyperthermia devices, it also has problems such as low energy utilization rate, uneven magnetic field and safety. new question
This is because: once the patient is pushed into the electromagnetic induction coil during the treatment by the above-mentioned tumor magnetic hyperthermia treatment apparatus, the whole patient will be in the alternating magnetic field with high field strength, and a large induced electromotive force will be generated on the surface of the human body, resultin...

Embodiment approach

[0045] Scheme 1: The magnetizer 15 is a single-loop structure, the length of the air gap 16 is fixed, and the air gap adjustment device 18 is not required;

[0046] Scheme 2: The magnetizer 15 is a double-loop structure, the length of the air gap 16 is fixed, and the air gap adjustment device 18 is not required;

[0047] Scheme 3: The magnetizer 15 is a single-loop structure, and the length of the air gap 16 is adjusted by moving the upper magnetic pole head of the magnetizer or the lower magnetic pole head of the magnetizer separately, and a set of air gap adjustment devices 18 is required;

[0048] Scheme 4: The magnetizer 15 is a single-loop structure, and the length of the air gap 16 is adjusted by moving the upper magnetic pole head of the magnetizer or the lower magnetic pole head of the magnetizer separately, or it can be adjusted by moving the upper magnetic pole head and the lower magnetic pole head of the magnetizer at the same time , two sets of air gap adjustment d...

Abstract

The tumor treating thermotherapeutic alternate magnetic field system in medical equipment field includes alternate power source system, magnetic field generating system, magnetic path system thermotherapeutic temperature measuring and feeding back system, alternate magnetic field strength measuring and feeding back system, treating bed system, shielding system and central operation and control system. The alternate magnetic field system has power source output frequency of 1-500 KHz, magnetic conductor made of soft magnetic material of high magnetic conductivity, cross section area of the magnetic conductor gap in 10-1000 sq cm, fixed or adjustable gap of 5-60 cm, and magnetic field strength inside the gap of 1-50 kA/m. Owing to magnetic path system comprising magnetic conductor and gap, the treating part of the alternate magnetic field system has homogeneous magnetic field distribution, high heating efficiency and reasonable heating mode.

Description

technical field [0001] The invention relates to a system in the technical field of medical equipment, in particular to a tumor alternating magnetic field hyperthermia system which utilizes an alternating magnetic field to generate heat from a ferromagnetic material. Background technique [0002] Tumor is one of the most important diseases that cause human death. The research on tumor treatment has always been the focus and focus of the medical field. After people's efforts, there have been many effective treatment methods, such as surgery, chemotherapy, radiotherapy, biological therapy, etc. therapy, heat therapy, etc. Among them, tumor hyperthermia refers to the technology and method of using the thermal effect of non-ionizing radiation physical factors in biological tissues to heat up the tissues and kill tumor cells, so as to achieve the purpose of treatment. Currently, the heating methods used in the clinical treatment of tumors include whole body heating with hot wax, ...
