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 a first open end and a second closed 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 comprises a main body, the main body comprising an annular sidewall and an annular shoulder extending radially inward from the annular sidewall and proximally from the second closed end, the annular shoulder having an end intersecting the annular sidewall distal from the first open end of the protective cap and another end intersecting the second closed end of the protective cap,
wherein the annular shoulder contacts the second end of the housing when the second end of the housing is received in the protective cap, and
wherein the second closed end of the protective cap comprises a base portion, the base portion comprising a flange extending radially outward from the main body of the protective cap and a bottom surface, the flange and the bottom surface being separated by a recess at least partially closed by the annular shoulder.

2. The syringe adapter of claim 1 , wherein the protective cap comprises an annular ring extending radially inward, and wherein the housing defines one or more recesses or protrusions positioned to engage the annular ring to form the snap fit.

3. The syringe adapter of claim 1 , wherein the protective cap comprises one or more projections extending radially inward, and wherein the one or more projections of the protective cap are positioned to engage one or more recesses or protrusions of the housing to form the snap fit.

4. 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 with respect to the cannula within the housing, the seal arrangement comprising a membrane; and
a protective cap having a first open end and a second open end positioned opposite the first end, the protective cap being configured to receive the second end of the housing therein, the protective cap having a restriction member configured to extend into the second end of the housing and engage a portion of the seal arrangement to prevent movement of the seal arrangement and the membrane with respect to the cannula,
wherein the restriction member comprises a tubular support extending proximally from a base portion of the protective cap, the tubular support 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 open end of the protective cap,
wherein the protective cap comprises an annular bottom surface and an annular shoulder that close the second open end of the protective cap radially outward from the second open end of the tubular support.

5. The syringe adapter of claim 4 , wherein the second end of the protective cap comprises a removable cover having an open position and a closed position.

6. The syringe adapter of claim 5 , 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.

7. The syringe adapter of claim 6 , 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.

8. The syringe adapter of claim 5 , 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 5 , 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 cover.

11. The syringe adapter of claim 5 , wherein, when in the open position, a swab is capable of being inserted through the open distal end of the protective cover for disinfecting at least a portion of the seal arrangement.

12. The syringe adapter of claim 4 , wherein the seal arrangement comprises a collet that receives the membrane, the restriction member engages a portion of the collet to restrict radial movement of the collet thereby preventing movement of the collet within the housing.

13. The syringe adapter of claim 4 , wherein the protective cap is connected to the housing via a snap fit.

14. The syringe adapter of claim 13 , wherein the protective cap comprises an annular ring extending radially inward, and wherein the housing defines one or more recesses or protrusions, and wherein the annular ring of the protective cap engages the one or more recesses or protrusions to form the snap fit.

15. The syringe adapter of claim 13 , wherein the protective cap comprises one or more projections extending radially inward, and wherein the housing defines one or more recesses or protrusions, and wherein the one or more projections of the protective cap engage the one or more recesses or protrusions of the housing to form the snap fit.

16. The syringe adapter of claim 4 , wherein the protective cap comprises a main body and a flange extending radially outward from the main body of the protective cap.

17. The syringe adapter of claim 4 , wherein the tubular support of the restriction member receives a disinfecting pad.

18. 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 restriction member connected to and extending proximally from the base portion of the annular body, the restriction member comprising a central channel extending between an open proximal end and an open distal end thereof; and
a cover connected to the base portion of the annular body,
wherein the annular body further comprises an annular shoulder extending radially inward from the annular sidewall and proximally from the distal base portion, the annular shoulder having an end intersecting the annular sidewall distal from the first open end of the protective cap and another end intersecting the distal base portion of the protective cap, and the annular shoulder being configured to contact an end of the syringe adapter when the protective cap is mounted to the syringe adapter,
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, and
wherein the distal base portion is closed by an annular bottom surface and the annular
