1. A drug administering apparatus comprising:
- a container with body fluid inlet and outlet ports which communicate with each other;
a liposome agent entrapping a drug therein; and
an insoluble substance fixed inside said container and having said liposome agent such that said liposome agent can be brought into contact with the body fluid flowing in said container;
said insoluble substance comprising a polymeric substance having a hydrophilic group and having been crosslinked to have a three-dimensional network structure;
said liposome agent being held between lattices of said network structure;
whereby said drug entrapped in said liposome agent is released into the body fluid flowing in said container.

Abstract
A drug administering apparatus includes a container with body fluid inlet and outlet ports which communicate with each other, and a liposome agent entrapping a drug therein. An insoluble substance is fixed inside the container and has the liposome agent such that the liposome agent can be brought into contact with the body fluid flowing in the container. The drug entrapped in the liposome is released into the body fluid flowing in the container.

12. A drug administering apparatus comprising:
-
a container with body fluid inlet and outlet ports which communicate with each other; a liposome agent entrapping a drug therein; and an insoluble substance fixed inside said container and having said liposome agent such that said liposome agent can be brought into contact with the body fluid flowing in said container; said insoluble substance being crosslinked to have a three-dimensional network structure; said insoluble substance being obtained by irradiating a mixture of a hydrogel comprising a polymeric substance and said liposome agent with gamma rays, thereby providing said network structure and allowing said liposome agent to be held between lattices of said network structure. - View Dependent Claims (13, 14, 15, 16)
