<P>PROBLEM TO BE SOLVED: To more easily mount a cartridge onto a warmer body in a warmer for a parenteral fluid such as an instillation liquid or blood. <P>SOLUTION: This warmer includes: a fulcrum which is arranged in one of the warmer body and the cartridge; and a hook part which is arranged in another so as to be engaged with the fulcrum. The cartridge is rotated with the fulcrum as a center in a state where the fulcrum is engaged with the hook part. Then the cartridge is inserted to the warmer body and fixed to a prescribed position of the warmer body through the use of a stopper disposed on the body. Correct positioning is not required in engaging the fulcrum with the hook part since a wedge-shaped opening is arranged in the hook part. The positional correlation between the warmer body and the cartridge is defined by the engagement of the fulcrum with the hook part, and hence attention does not need to be paid to positioning in two places or more as in conventional technique. Consequently, attachment is easily performed. <P>COPYRIGHT: (C)2004,JPO |
