Abstract

A syringe adapter is provided. The adapter includes a housing having a first end and a second end positioned opposite the first end. The first end of the housing has a connector configured to be secured to a syringe barrel. The adapter also includes a cannula positioned within the housing and a seal arrangement including a membrane or septum positioned within the housing and movable within the housing, the seal arrangement comprising a membrane. The assembly can also include a protective cap having a first open end and a second closed end. The protective cap can be connected to the housing via a snap fit and can be configured to receive the second end of the housing.

First claim

The invention claimed is:

1. A syringe adapter comprising:
a housing having a first end and a second end positioned opposite the first end, the first end of the housing having a connector configured to be secured to a syringe barrel;
a cannula positioned within the housing;
a seal arrangement positioned within the housing and movable within the housing, the seal arrangement comprising a membrane; and
a protective cap having an annular body with a first end and a second end, the protective cap being connected to the housing via a snap fit and receiving the second end of the housing,
wherein the protective cap further comprises a tubular support and an annular base portion connected between the annular body and the tubular support comprising an annular bottom surface, the tubular support extending proximally from the annular base portion toward the first end of the annular body and comprising a central channel extending between a first open end and a second open end of the tubular support, the central channel being open from the first open end to the second open end and configured to provide access to an interior of the housing via the second end of the protective cap, and
wherein the second end of the protective cap comprises a removable cover having an open position and a closed position.

2. The syringe adapter of claim 1 , wherein at least one of the annular base portion and the removable cover of the protective cap comprises a locking mechanism for maintaining the removable cover in the closed position.

3. The syringe adapter of claim 2 , wherein locking mechanism comprises a proximally extending lip having a detent extending from the removable cover and configured to engage a portion of the annular body.

4. The syringe adapter of claim 3 , wherein the detent is positioned to engage a corresponding projection on the base portion of the protective cap.

5. The syringe adapter of claim 1 , wherein the housing comprises an annular groove on an outer surface thereof, and wherein the first end of the annular body of the protective cap comprises one or more protrusions extending radially inward engaged to the annular groove of the housing to form the snap fit.

6. The syringe adapter of claim 1 , wherein when the removable cover is in the open position, a portion of the membrane of the seal arrangement is accessible via the second end of the protective cap and the second open end of the tubular support.

7. The syringe adapter of claim 1 , wherein when the removable cover is in the closed position, the membrane of the seal arrangement is inaccessible via the second end of the protective cap and the second open end of the tubular support.

8. The syringe adapter of claim 1 , wherein the removable cover comprises a living hinge to allow the removable cover to move between the open position and the closed position.

9. The syringe adapter of claim 1 , wherein the removable cover further comprises a protruding latch configured to engage a radially outer portion of the protective cap to maintain the cover in the closed position.

10. The syringe adapter of claim 9 , wherein the removable cover comprises a first end pivotally connected to the protective cap and a second end opposite the first end, and wherein the latch extends from the second end of the removable cover.

11. The syringe adapter of claim 1 , wherein, when in the open position, a swab is capable of being inserted through the first open end and the second open end of the tubular support for disinfecting at least a portion of the seal arrangement.

12. The syringe adapter of claim 1 , wherein the tubular support extends beyond the first end of the annular body of the protective cap.

13. The syringe adapter of claim 12 , wherein the tubular support is inserted through an opening in the second end of the housing with the first open end of the tubular support contacting a portion of the seal arrangement to prevent movement of the seal arrangement with respect to the cannula.

14. The syringe adapter of claim 1 , wherein the second end of the syringe adapter housing is received within an interior of the protective cap through the first end of the annular body.

15. The syringe adapter of claim 1 , wherein when the removable cover is in the closed position, a proximal surface of the removable cover contacts the annular bottom surface of the protective cap and covers the open second end of the tubular support.

16. A protective cap configured to be removably mounted to a syringe adapter, the cap comprising:
an annular body comprising a proximal portion configured to engage the syringe adapter, a distal base portion, and an annular sidewall extending therebetween;
a retention member extending proximally from the distal base portion of the annular body, wherein the distal base portion comprises an annular bottom surface extending between the annular body and the retention member, the retention member comprising a central channel extending between an open proximal end and an open distal end thereof; and
a cover coupled to the base portion of the annular body,
wherein the cover is transitionable from a closed position in which it covers the distal open end of the central channel, and an open position in which a swab is capable of being inserted through the open distal end of the central channel for disinfecting an interior of the syringe adapter.

17. The protective cap of claim 16 , wherein at least one of the distal base portion and the cover comprises a locking mechanism for maintaining the cover in the closed position,
wherein the locking mechanism comprises a proximally extending lip having a detent extending from the cover and configured to engage a portion of the annular body, and
wherein the detent is positioned to engage a corresponding projection on the distal base portion of the protective cap.

18. The protective cap of claim 16 , wherein the proximal portion of the annular body comprises one or more protrusions extending radially inward configured to engage an annular groove on an outer surface of the housing.

19. The protective cap of claim 16 , wherein the cover comprises a living hinge to allow the cover to move between the open position and the closed position, and/or
wherein the cover comprises a first end pivotally connected to the protective cap and a second end opposite the first end, wherein a latch extends from the second end of the cover.

20. The protective cap of claim 16 , wherein the retention member extends proximally beyond the proximal portion of the annular body.
