Closed drug transfer system
First Claim
1. A vial adaptor comprising:
- (a) a bottom part adapted to be attached to the head section of a medical vial or any type of vessel or device that has a head section similar to that of the head of a standard medicine vial;
(b) a top part comprising;
(i) a disk shaped central piece and a plurality of wings adapted for facilitating securement of said top part to said bottom part, said wings attached to the circumference of said disk shaped central piece and projecting distally away from it;
(ii) a longitudinal extension projecting proximally from said disk shaped central piece, said longitudinal extension adapted to be coupled to a fluid transfer device;
(iii) a membrane that seals the proximal end of said longitudinal extension;
(iv) a spike element which protrudes distally from the center of said disk shaped central piece;
(v) an air channel and a liquid channel both of which are internally formed within said longitudinal extension and said spike element, said channels adapted to allow fluid communication through said vial adapter from said proximally located membrane to openings at the tip of said spike, thereby providing a closed transfer device that does not vent to or communicate with the environment;
(c) a first locking mechanism; and
(d) a second locking mechanism;
wherein, said first locking mechanism is adapted to lock said top part to said bottom part such that the tip of said spike cannot contact a stopper in said head section when said head section is being attached to said bottom part and to release said top part from said bottom part after said bottom part has been attached to said head section; and
said second locking mechanism is adapted to allow, after said bottom part has been attached to said head section, said spike to penetrate said stopper in said head section and to irremovably lock said top part to said bottom part.

Abstract
A vial adaptor having a bottom part adapted to be attached to the head section of a medical vial or any type of vessel or device that has a head section similar to that of the head of a standard medicine vial. The top part has numerous components. The apparatus also has a first locking mechanism; and a second locking mechanism. The first locking mechanism is adapted to lock a top part to the bottom part such that a tip of a spike cannot contact a stopper in the head section when the head section is being attached to the bottom part and to release the top part from the bottom part after the bottom part has been attached to the head section. The second locking mechanism is adapted to allow, after the bottom part has been attached to the head section, the spike to penetrate the stopper in the head section and to irremovably lock the top part to the bottom part.

10. A vial adaptor comprising:
-
(a) a distal collar portion comprised of a disk shaped central piece and a plurality of segments adapted for facilitating securement of said vial adaptor to a head portion of a vial, said segments attached to the circumference of said disk shaped central piece and projecting distally away from it; (b) a longitudinal extension projecting proximally from said disk shaped central piece; (c) a membrane that seals the proximal end of said longitudinal extension; (d) a spike element which protrudes distally from the center of said disk shaped central piece; (e) an air channel and a liquid channel both of which are internally formed within said longitudinal extension and said spike element, said channels adapted to allow fluid communication through said vial adapter from said proximally located membrane to openings at the tip of said spike, thereby providing a closed transfer device that does not vent to or communicate with the environment; wherein an annular shaped flat hydrophobic filter is located in said disk shaped central piece, said vial adaptor and said filter adapted to allow fluid flowing in said liquid channel to pass through said vial adapter without passing through said filter and to prevent liquid flowing through said air channel from passing through said filter and to allow air flowing through said air channel to pass through said filter. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
