Multi-frequency and multipoint heating device

Abstract

The invention discloses a multi-frequency and multipoint heating device which comprises a heating device body and a heating tank. The heating device body comprises a molecular ring and a heater for heating the heating tank. The heater comprises a base and a sleeve mounted on the base. An induction coil winds the sleeve. A plurality of magnetic field generators for heating the heating tank coaxially fixedly sleeve the sleeve. The molecular ring sleeves the magnetic field generators. The heating tank is disposed in the sleeve. An inductor for inducting the magnetic field generators and the magnetic field generated by the coil is disposed in the heating tank. The multi-frequency and multipoint heating device has the advantages that by the molecular ring and the heater, the heating mode of the heating tank is changed into multi-frequency and multipoint heating including layered heating, alternate heating and simultaneous heating by adjusting one or more of the magnetic field generators according to water temperature conditions, even heating is achieved, uneven heating temperature caused by one-face single-point heating is avoided, heating is assisted by the molecular ring, and heat exchanging efficiency is increased.

Description

technical field [0001] The invention relates to a medical device, in particular to a multi-frequency and multi-point heating device. Background technique [0002] Malignant tumors in the thoracoabdominal cavity are easy to metastasize and recur in the cavity, often causing a large amount of cancerous intracavitary effusion, especially for gastrointestinal cancer, 50% of patients relapse within one year after surgery, 80% of patients relapse within two years, and up to 50% of patients relapse within four years. 90%, is the main cause of death. [0003] At present, the chemotherapy of malignant tumors in the thoracoabdominal cavity and the concentrated ascites reinfusion treatment are generally carried out with a hot perfusion machine. The hot perfusion machine mainly includes a control system and a heating perfusion system. The heating perfusion system is connected to the control system and controlled by the control system. [0004] However, the heating system in the existin...

Problems solved by technology

[0004] However, the heating system in the existing heating and perfusion system is structured as electromagnetic induction heating. Although electromagnetic induction heating can heat quickly, because it is a single-point heating on one surface, part of the liquid in the heating tank will be heated, and part of it will still be hot. Without heat, it is easy to cause uneven temperature heating

[0005] At the same time, the heating tank in the current heating perfusion system is only a simple liquid storage for the liquid with cancer cells stored therein, and cannot be effectively treated, and because the heating system heats the liquid in the heating tank at a single point, Therefore, the temperature of the liquid in the heating tank will be uneven
