An enhancement water system to produce a serving of enhanced filtered water is described. The apparatus of the present invention provides an enclosure connectable to the machine foundation. Optionally, the medical device further comprises a haemostatic coating surrounding the outer body. Tape reels housed in a cassette case can be urged toward the lower half by a member whose structure is simple and permits easy fitting and removal. The resultant conductive rod structure is cut axially along the length of the conductive rod to generate conductive buttons having end contacts.
