Claims13
An apparatus for use in securing a piercing device having flanges to a delivery container such as a vial or bottle particularly when instilling a medicinal fluid into a patient through an intravenous set, catheter or similar fluid delivery set, said apparatus comprising:
- a cylindrical body having an axis, first and second ends, and inner and outer cylindrical surfaces extending between the first and second ends, the outer cylindrical surface having a circumference, said cylindrical body including:
- a plurality of axially extending slots spaced around the circumference of the cylindrical body at the first end thereof, for expanding when assembling the apparatus onto the delivery container,
- at least two ports, each extending between the inner and outer cylindrical surfaces of the cylindrical body at the second end thereof, and extending circumferentially partly around said cylindrical body, for fittingly engaging the piercing device flanges, and
- an inwardly extending lip portion disposed at the first end of the cylindrical body, for fittingly engaging a delivery container seal.
An apparatus for use in securing a piercing device having flanges to a delivery container such as a vial or bottle particularly when instilling a medicinal fluid into a patient through an intravenous set, catheter or similar fluid delivery set, said apparatus comprising:
- an outer peripheral wall;
- first means for fittingly engaging an end of the delivery container, including first securing means for securing the apparatus to the delivery container, and expanding means for expanding during assembly of the apparatus onto the delivery container;
- and
- second means for fittingly engaging the piercing device, including aperture means extending entirely through the outer peripheral wall for securing the piercing device to the apparatus by receiving the flanges of the piercing device therein.
An apparatus for use in securing a piercing device having flanges to a delivery container such as a vial or bottle particularly when instilling a medicinal fluid into a patient through an intravenous set, catheter or similar fluid delivery set, said apparatus comprising:
- first means for fittingly engaging an end of the delivery container, including first securing means for securing the apparatus to the delivery container, and expanding means for expanding during assembly of the apparatus onto the delivery container;
- and
- second means for fittingly engaging the piercing device, including second securing means for securing the piercing device to the apparatus by receiving the flanges of the piercing device therein, said second means further including first cutout means for receiving an air inlet filter of the piercing device therethrough.
In a method of instilling a medicinal fluid to a patient through a fluid delivery set, the improvement comprising securing a piercing device having a flange to a delivery container utilizing an apparatus having a cylindrical body having an axis, first and second ends, and inner and outer cylindrical surfaces extending between the first and second ends, the outer cylindrical surface having a circumference, said cylindrical body including:
- a plurality of axially extending slots spaced around the circumference of the cylindrical body at the first end thereof, for expanding when assembling the apparatus onto the delivery container,
- at least two ports, each extending between the inner and outer cylindrical surfaces of the cylindrical body at the second end thereof, and extending circumferentially partly around said cylindrical body, for fittingly engaging a flange of the piercing device, and
- an inwardly extending lip portion disposed at the first end of the cylindrical body, for fittingly engaging a delivery container seal, wherein the piercing device is a vented piercing pin.
