The teachings of Farris
The primary object of Farris' invention was to provide a method and apparatus for
transferring sterile fluid from an ampule to a hypodermic syringe without the need of a
hypodermic needle. Farris discloses a needleless dosage transfer system for filling
medicating devices such as syringes or needleless cannulas to minimize the likelihood
of an unwanted needle stick and to avoid the initial cost of a needle as well as the
disposal cost of the needle. As shown in Figures 1-6, Farris' needleless dosage transfer
system includes a vial or ampule 10 formed from two parts: a body portion 20 and a cap
portion 40. The body portion 20 is formed with flexibly deformable walls and defines a
blind bore. An opening of the vial includes a tapered section 8 adapted to frictionally fit
over a taper of a male luer-type fitting commonly found on syringes and
needleless cannulas. By deforming the walls of the vial, fluid is forced from the vial into
a syringe or needleless cannula. The opening of the vial is protected by the cap portion
40 and includes a scoreline which, when fractured, defines the opening. The cap
portion which is to be removed from the vial prior to its use is fabricated as one piece
with the body portion in order to assure sterile conditions during manufacture and filling.
A tab 42 is associated with the cap portion which lists the ingredients within the vial.
The body portion also supports an area which lists the vial's contents.
