Cryoballoon control apparatus, catheter system, and temperature display method

A cryoballoon catheter system, comprising a control device, a cryoballoon catheter and a display device, wherein the cryoballoon catheter comprises a cryoballoon, a center temperature sensor disposed at a center of the cryoballoon and a plurality of circumference temperature sensors circumferentially disposed on the cryoballoon, wherein each of the center temperature sensor and the circumference temperature sensors is communicatively connected to the control device, wherein the display device is communicatively connected to the control device, wherein the display device is provided with an input field for receiving a preset balloon temperature;

• wherein the control device is connected to the cryoballoon catheter and is configured to:
• acquire a plurality of balloon circumference temperature values obtained by a plurality of circumference temperature sensors of the cryoballoon catheter, and a balloon center temperature value obtained by a center temperature sensor of the cryoballoon catheter;
• and
• automatically adjust a flow rate of coolant introduced into a cryoballoon in the cryoballoon catheter based on a comparison between a preset balloon temperature value and a comparative temperature value to enable a temperature control of the cryoballoon, wherein the comparative temperature value is the balloon center temperature value, or any one of the plurality of balloon circumference temperature values, or a computational temperature value derived by a predefined algorithm from the plurality of balloon circumference temperature values,
• wherein the cryoballoon catheter system is configured to:
• display a balloon center temperature representation graph on the display device based on the balloon center temperature value;
• and
• display a plurality of balloon circumference temperature representation graphs on the display device based on the plurality of balloon circumference temperature values, wherein the plurality of balloon circumference temperature representation graphs surround the balloon center temperature representation graph;
• wherein each balloon circumference temperature representation graph comprises a balloon circumference temperature condition graph configured to indicate a normal condition or a first alert condition, wherein the normal condition indicates that the balloon circumference temperature value obtained by the corresponding circumference temperature sensor lies within the first predetermined threshold range, so prompts the operator that a temperature of the cryoballoon is appropriate, and in an event of any one of the plurality of balloon circumference temperature values exceeding a first predetermined threshold range, a corresponding one of the balloon circumference temperature representation graphs indicates the first alert condition to prompt an operator to adjust a temperature of the cryoballoon.
