Abstract:
1. A delivery apparatus for medical fluids, comprising: an outer casing including an upper case and a lower case; a tubular body having opposed ends connected with one another, said tubular body being expandable and contractible such that said tubular body expands when medical fluids are injected into said tubular body, and said medical fluids are expelled by pressure produced by subsequent contraction of said tubular body; a branch conduit connectably joining said opposed ends of said tubular body to one another, said branch conduit including an injection port for injection of medical fluids into said tubular body, said injection port being exposed to an outside of said upper case; a projecting holder being integrally formed with said upper case at a center of said upper case so as to be disposed centrally of an interior of said outer casing said projecting holder extending axially between said upper and lower cases, said tubular body being circumferentially wound about said projecting holder, an inner wall of said lower case being tightly fitted in parallel to the projecting holder so as to occlude or eliminate any space therebetween to thereby prevent the tubular body wound on the projecting holder from separating and being crushed, said projecting holder including a groove dimension with a width sufficient to fittably receive said branch conduit and said lower case includes an internally disposed protrusion which faces said branch conduit so as fix the branch conduit in place within said groove; and a hose for delivery of the medical fluids extending through said outer casing and connecting to said branch conduit within said outer casing.
