Document Type and Number:
WIPO Patent Application WO/2022/239760
Kind Code:
A1
Abstract:
[Problem] To provide: an oxygen concentration measurement method that is for infusion solution bags and that makes it possible to ensure a detection space required for a gas phase part in an infusion solution bag and improve measurement accuracy; and an infusion solution bag for use in the oxygen concentration measurement method. [Solution] An infusion solution bag H has a shoulder part 12 in which both side lower edge parts 11a, 11b rise obliquely upward toward the center, a port 13 provided to the center of the shoulder part 12, and a gas phase part 14 provided to a lower portion of the shoulder part 12. This oxygen concentration measurement method for infusion solution bags involves measuring the oxygen concentration in the infusion solution bag H, by providing, to both outsides of a gas phase part 14 directly below the port 13, a leading end part 16 of a laser generation unit 15 and a leading end part 18 of a laser reception unit 17 opposite to each other.
