Control system and control method of device for hyperthermic perfusion treatment

Abstract

The present invention provides a control system and a control method of a device for a hyperthermic perfusion treatment. The control system comprises a variable-speed peristaltic pump, transfusion guide pipes and a heating tank body; the variable-speed peristaltic pump comprises a pump head and a driving device; the transfusion guide pipes comprises a first guide pipe and a second guide pipe; oneend of the first guide pipe and one end of the second guide pipe are arranged in the heating tank body in a sealed mode, and the pump head is connected on the first guide pipe or the second guide pipein a pressing manner; the driving device is used for receiving preset time-varying signals and controlling the pump head to rotate in a positive direction within a first preset time period accordingto the preset time-varying signals including direction time-varying signals to enable medicine liquid to enter an inner cavity of a human body from the heating tank body through the first guide pipe;and the driving device is used for controlling the pump head to rotate in an opposite direction in a second preset time period according to the preset time-varying signals to enable the medicine liquid to enter the inner cavity of the human body from the heating tank body through the second guide pipe. The control system can realize full heating of cavity walls and organs, enables the medicine liquid to flush rear sides of the organs, enables an area which is not fully heated originally under a winding-column eddy current to be fully heated, and improves a treatment effect on a patient.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a control system and a control method of a heat perfusion treatment equipment. Background technique [0002] In traditional thermoperfusion therapy equipment, the liquid medicine control system usually includes pumps, infusion catheters and heating tanks. Among them, in the circulation mode, under the pressurization of the pump, the medicinal liquid can generate a certain pressure and flow rate, so that the medicinal liquid heated in the heating tank enters the inner cavity of the human body through the catheter into the body, and the pressurized Under the negative pressure generated by the pump, the medicinal liquid can flow from the human body cavity into the outlet catheter and return to the heating tank to continue heating. That is to say, under the pressure of the booster pump, the medicinal liquid can pass through the catheter into the human body cavity at a pred...

Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a control system and control method for the thermal perfusion treatment equipment, which can realize the destruction of the medical solution. Laminar flow, so that the medicine liquid enters the human body cavity to achieve comprehensive flushing and full replacement of high-temperature and low-temperature medicine liquids, thereby enhancing the effect of thermoperfusion therapy
