Septum housing
First Claim
1. A catheter assembly, comprising:
- a catheter adapter, wherein the catheter adapter comprises a distal end, a proximal end, an inner wall extending between the distal end and the proximal end, and a lumen formed by the inner wall;
a septum housing disposed within the lumen of the catheter adapter, wherein the septum housing comprises one or more protrusions, wherein the one or more protrusions comprise a lip that extends around an outer circumference of the septum housing, wherein the septum housing is secured to the inner wall by bonding between the one or more protrusions and the inner wall, wherein the bonding between the one or more protrusions and the inner wall comprises adhesive bonding, wherein the inner wall comprises a ring that contacts an exterior of the septum housing and is spaced apart from the lip such that a cavity is formed between the ring and the lip, wherein the adhesive bonding contacts the ring, wherein a venting pathway provides access to the cavity; and
a septum at least partially disposed within the septum housing and configured to at least substantially seal the lumen.

Abstract
A catheter assembly may include a catheter adapter, a septum housing, and a septum. The catheter adapter may include a distal end, a proximal end, an inner wall extending between the distal end and the proximal end, and a lumen formed by the inner wall. The septum housing may include one or more protrusions and may be secured to the inner wall by one or more of the following: an interference fit between the one or more protrusions and the inner wall, a snap fit between the one or more protrusions and the inner wall, and bonding between the one or more protrusions and the inner wall. The septum may be at least partially disposed within the septum housing and configured to at least substantially seal the lumen.

6. A catheter assembly, comprising:
-
a catheter adapter, wherein the catheter adapter comprises a distal end, a proximal end, an inner wall extending between the distal end and the proximal end, a lumen formed by the inner wall, and a side port, wherein the inner wall comprises a groove or opening; a septum housing disposed within the lumen of the catheter adapter, wherein the septum housing comprises one or more protrusions, wherein in response to the septum housing being inserted into the distal end of the catheter adapter, the one or more protrusions are biased inwardly, wherein in response to the one or more protrusions being further inserted into the distal end and aligning with the groove or opening, the one or more protrusions move resiliently outward such that the one or more protrusions are retained in the groove or opening, wherein the one or more protrusions comprise a lip that extends around an outer circumference of the septum housing, wherein the septum housing is secured to the inner wall by bonding between the one or more protrusions and the inner wall, wherein the inner wall comprises a ring that contacts an exterior of the septum housing and is spaced apart from the lip such that a cavity is formed between the ring and the lip, wherein the bonding contacts the ring; a vent hole disposed within the inner wall of the catheter adapter, wherein the vent hole provides a venting pathway between an exterior of the catheter assembly and the bonding; and a septum at least partially disposed within the septum housing and proximal to the side port, wherein the septum is configured to at least substantially seal the lumen. - View Dependent Claims (7, 8, 9, 10)
