Document Type and Number:
WIPO Patent Application WO/2004/014465
Kind Code:
A1
Abstract:
With a medicine liquid injection device (100), a subject and syringes (201, 202) are connected by a subject tube (223) and syringe tubes (221, 222). When medicine liquid is injected to the subject from one of the syringes (201, 202), one of the syringe tubes (221, 222) connected to the other syringe (201 or 202) is closed, so that the medicine liquid injected to the subject from the one of the syringes (201, 202) does not flow back to the other syringe (201 or 202). Therefore, plural kinds of medicine liquid can be injected to the subject without restriction and the liquid can be prevented from flowing back.
