Abstract

An infusion fluid heating apparatus applicable to various types of infusion tube with different length dimensions includes a front-side tube fitting groove or a rear-side tube fitting groove formed on one of surfaces of a heating plate that receives an infusion tube in a first length between an inlet opening and an outlet opening open at the end surfaces of the heating plate. The groove also receives the infusion tube in a second length shorter than the first length. Therefore, the groove uses the second length for a relatively short infusion tube, capable of heating the tube appropriately and achieving high versatility. In addition, the tube fitting groove uses the first length for an infusion bag with a relatively long infusion tube, capable of heating the tube appropriately and increasing the maximum infusion fluid flow.

Claims

1-6. -6. (canceled)

7. An infusion fluid heating apparatus, having a heating plate formed on one surface thereof a tube fitting groove receiving a infusion tube, for pre-heating an infusion fluid to be supplied to a living body through the infusion tube to a preset temperature, wherein the tube fitting groove formed on one surface of the heating plate receives the infusion tube in a first length between an inlet opening and an outlet opening both opened at an end surface of the heating plate, and also receives the infusion tube in a second length shorter than the first length.

8. The infusion fluid heating apparatus according to claim 7, wherein the tube fitting groove includes a basic groove formed in the first length between the inlet opening and the outlet opening, and a shunting groove shunting the basic groove in a middle thereof so that the second length is defined between the inlet opening and the outlet opening.

9. The infusion fluid heating apparatus according to claim 7, further comprising a case to which the heating plate is detachably attached, wherein the heating plate in formed on other surface thereof a second tube fitting groove having a different sectional shape from the tube fitting groove formed on the one surface.

10. The infusion fluid heating apparatus according to claim 8, further comprising a case to which the heating plate is detachably attached, wherein the heating plate in formed on other surface thereof a second tube fitting groove having a different sectional shape from the tube fitting groove formed on the one surface.

11. The infusion fluid heating apparatus according to claim 9, wherein the second tube fitting groove receives the infusion tube in a third length between an inlet opening and an outlet opening both opened at the end surface of the heating plate, and also receives the infusion tube in a third length which is shorter than the first length.

12. The infusion fluid heating apparatus according to claim 10, wherein the second tube fitting groove receives the infusion tube in a third length between an inlet opening and an outlet opening both opened at the end surface of the heating plate, and also receives the infusion tube in a third length which is shorter than the first length.

13. The infusion fluid heating apparatus according to claim 7, wherein the case contains an electrical heater closely fit to the heating plate, a temperature sensor directly or indirectly detecting a temperature of the infusion fluid in the infusion tube near the outlet opening, and a control unit controlling a heat generation amount of the electrical heater so that the temperature detected by the temperature sensor coincides with a preset target temperature.

14. The infusion fluid heating apparatus according to claim 8, wherein the case contains an electrical heater closely fit to the heating plate, a temperature sensor directly or indirectly detecting a temperature of the infusion fluid in the infusion tube near the outlet opening, and a control unit controlling a heat generation amount of the electrical heater so that the temperature detected by the temperature sensor coincides with a preset target temperature.

15. The infusion fluid heating apparatus according to claim 9, wherein the case contains an electrical heater closely fit to the heating plate, a temperature sensor directly or indirectly detecting a temperature of the infusion fluid in the infusion tube near the outlet opening, and a control unit controlling a heat generation amount of the electrical heater so that the temperature detected by the temperature sensor coincides with a preset target temperature.

16. The infusion fluid heating apparatus according to claim 10, wherein the case contains an electrical heater closely fit to the heating plate, a temperature sensor directly or indirectly detecting a temperature of the infusion fluid in the infusion tube near the outlet opening, and a control unit controlling a heat generation amount of the electrical heater so that the temperature detected by the temperature sensor coincides with a preset target temperature.

17. The infusion fluid heating apparatus according to claim 11, wherein the case contains an electrical heater closely fit to the heating plate, a temperature sensor directly or indirectly detecting a temperature of the infusion fluid in the infusion tube near the outlet opening, and a control unit controlling a heat generation amount of the electrical heater so that the temperature detected by the temperature sensor coincides with a preset target temperature.

18. The infusion fluid heating apparatus according to claim 12, wherein the case contains an electrical heater closely fit to the heating plate, a temperature sensor directly or indirectly detecting a temperature of the infusion fluid in the infusion tube near the outlet opening, and a control unit controlling a heat generation amount of the electrical heater so that the temperature detected by the temperature sensor coincides with a preset target temperature.

19. The infusion fluid heating apparatus according to claim 13, wherein the case is provided with an infusion bag containing the infusion fluid, in place of the heating plate.

20. The infusion fluid heating apparatus according to claim 14, wherein the case is provided with an infusion bag containing the infusion fluid, in place of the heating plate.

21. The infusion fluid heating apparatus according to claim 15, wherein the case is provided with an infusion bag containing the infusion fluid, in place of the heating plate.
