Abstract

The closed system medication administering system employs an adaptor having a hollow penetrating which can directly access a drug vial by piercing through a bung in the drug vial. A collapsible sleeve is placed around the hollow penetrating member and a membrane is disposed across the end of the sleeve to seal the hollow penetrating member when not in use. The hollow penetrating member also pierces the membrane when pushed into a drug vial. Resilient locking prongs may be provided to fixedly secure the drug vial to the adaptor or may be omitted. A reservoir bag may also be provided in a second line to fill with fluid from the primary line in order to effect reconstitution or dilution of a powdered or crystalline type drug in the drug vial. Simple manipulations of the unit consisting of the flexible bag, adaptor and drug vial allow the powdered drug to be reconstituted or diluted and subsequently dispensed.

Claims

1. A closed system medication administering system comprising

an IV container for dispensing a fluid under gravity;

a primary line communicating with said IV container to receive and convey fluid therefrom;

an access device communicating with said primary line to deliver fluid to a patient;

a Y-site connector in said primary line having a side arm communicating with said primary line;

an adaptor for coupling with a drug vial, said adaptor including a collapsible sleeve with a membrane disposed across one end to seal against a hollow penetrating member contained within said sleeve for penetrating through said membrane into said vial in response to said sleeve collapsing; and

a second line communicating with said penetrating member to receive the contents of the drug vial and communicating with said arm of said Y-site to deliver the vial contents to said primary line.

2. A system as set forth in claim 1 wherein said adaptor includes a resilient locking means for releaseably engaging with a drug vial.

3. A system as set forth in claim 2 wherein said locking means includes a pair of oppositely facing prongs, each said prong having at least one inwardly directed projection for engaging with a recessed portion of a drug vial.

4. A system as set forth in claim 1 which further comprises a hanger having said adaptor mounted thereon for suspending said adaptor from a support.

5. A system as set forth in claim 1 wherein said adaptor includes an air vent for venting air therefrom and a cap for selectively sealing said air vent.

6. A system as set forth in claim 5 wherein said air vent communicates with the interior of said hollow penetrating member.

7. A system as set forth in claim 5 wherein said hollow penetrating member has a pair of parallel lumen, one of said lumen communicating with said air vent and the other of said lumen communicating with said second line.

8. A system as set forth in claim 1 which further comprises a releasable clamp on said second line for selectively blocking flow through said second line.

9. A system as set forth in claim 1 further comprising a flexible bag disposed between and in communication with said penetrating member and said second line to receive fluid from one of said penetrating member and said second line.

10. A system as set forth in claim 9 which further comprises a support secured to one exterior side of said bag and a pull tab secured to an opposite exterior side of said bag for selectively pulling said sides apart to draw a vacuum in said spike for emptying the contents of a drug vial.

11. A system as set forth in claim 1 further comprising an air venting filter in said secondary line.

12. A closed system medication administering system comprising

an IV container for dispensing a fluid under gravity;

a drip chamber in communication with said IV container;

a primary line communicating with said drip chamber to receive and convey fluid therefrom;

an access device communicating with said primary line to deliver fluid to a patient;

an adaptor for coupling with a drug vial, said adaptor including a collapsible sleeve with a membrane disposed across one end to seal against a hollow penetrating member contained within said sleeve for penetrating through said membrane into said vial in response to said sleeve collapsing;

a second line connected to said drip chamber in parallel with said primary line, said second line communicating with said penetrating member to receive the contents of the drug vial and communicating with said primary line to deliver the vial contents thereto; and

a clamp for selectively closing at least one of said primary line and said second line.

13. A system as set forth in claim 12 wherein said adaptor includes an air vent for venting air therefrom and a cap for selectively sealing said air vent.

14. A closed system medication administering system comprising

an IV container for dispensing a fluid under gravity;

a drip chamber in communication with said IV container;

a primary line communicating with said drip chamber to receive and convey fluid therefrom;

an access device communicating with said primary line to deliver fluid to a patient;

an adaptor for coupling with a drug vial, said adaptor including a collapsible sleeve with a membrane disposed across one end to seal against a hollow penetrating member disposed concentrically within said sleeve for piercing through said membrane into said vial in response to said sleeve collapsing;

a second line communicating with said penetrating member to receive the contents of the drug vial and connected between said IV container and said drip chamber to deliver the vial contents to said drip chamber; and

a flow control device for controlling flow through said second line.

15. A system as set forth in claim 14 wherein said adaptor includes an air vent for venting air therefrom and a cap for selectively sealing said air vent.

16. A system as set forth in claim 14 wherein said flow control device is a releasable clamp on said second line for selectively blocking flow through said second line.

17. A closed system medication administering system comprising

an IV container for dispensing a fluid under gravity;

a volume control tube connected to said IV container to receive fluid therefrom;

a drip chamber extending from said tube;

a primary line extending from said drip chamber to convey fluid therethrough;

an adaptor on one end of said tube for coupling with a drug delivery means, said adaptor including a collapsible sleeve with a membrane disposed across one end to seal against the drug delivery means and a hollow penetrating member concentrically within said sleeve for penetrating through said membrane into the drug delivering means in response to said sleeve collapsing; and

an air vent on said one end of said tube for venting air therefrom.

18. In combination,

a bag for receiving fluid;

a line extending from said bag to convey fluid therebetween; and

an adaptor extending from said bag for coupling with a drug vial, said adaptor including a collapsible sleeve with a membrane disposed across one end to seal against a hollow penetrating member within said sleeve for penetrating through said membrane into said vial in response to said sleeve collapsing;

said penetrating member being in communication with said bag.

19. The combination as set forth in claim 18 wherein said adaptor includes a resilient locking means for releaseably engaging with a drug vial.

20. The combination as set forth in claim 19 wherein said locking means includes a pair of oppositely facing tangs, each said tang having at least one inwardly directed projection for engaging with a recessed portion of a drug vial.

21. The combination as set forth in claim 18 further comprising an injection site communicating with said bag, said site including a housing and a rubber disc within said housing to seal said site.

22. The combination as set forth in claim 21 further comprising a reservoir, a collapsible sleeve communicating with said reservoir, a membrane across one end of said sleeve and a hollow penetrating member within said sleeve and communicating with said reservoir for penetrating said rubber disc of said injection site.

23. The combination as set forth in claim 22 wherein said reservoir is a syringe.

24. A closed system medication administering system comprising

an IV container for dispensing a fluid under gravity;
