Abstract

A method and apparatus are disclosed for positioning a compression member about the septum of a seal member. In one embodiment, a source of low pressure or vacuum is provided to draw the septum of seal member into the hollow body of the compression member. In an alternative embodiment, a molding apparatus is provided which is dimensioned to receive a compression member and configured to facilitate molding of the septum within the compression member. In another embodiment, the septum of the seal member includes a septum having a tab extending from the septum. The tab is configured to assist positioned of a compression member about the septum.

Claims

1. An IV catheter device comprising:

a housing defining a chamber;

a seal member positioned within the chamber, the seal member including a sealing portion which is positioned to engage a seating surface within the housing to seal a proximal portion of the chamber from a distal portion of the chamber; and

a locking member positioned within the chamber of the housing, the locking member being positioned about and engaging the seal member to position the sealing portion of the seal member in engagement with the seating surface, the locking member including at least one channel connecting a proximal portion of the chamber to a distal portion of the chamber;

wherein when the sealing portion of the seal member is moved from engagement with the seating surface within the housing, fluid can flow about the sealing member and through the at least one channel to the distal portion of the chamber.

2. The IV catheter device according to claim 1, wherein the locking member has a substantially annular body.

3. The IV catheter according to claim 2, wherein an external periphery of the locking member is secured to an inner wall of the housing and an internal periphery of the locking member is secured to the seal member.

4. The IV catheter device according to claim 3, wherein the inner periphery of the locking member includes an annular rim configured to receive a distal end of the seal member.

6. The IV catheter device according to claim 1, further including a tubular member defining a lumen in fluid communication with the distal portion of the chamber.

5. An IV catheter device comprising:

a housing defining a chamber;

a seal member positioned within the chamber, the seal member including sealing portion which is positioned to engage a seating surface within the housing to seal a proximal portion of the chamber from a distal portion of the chamber;

a locking member having a substantially annular body positioned within the chamber of the housing, the locking member being positioned about and engaging the seal member to position the sealing portion of the seal member in engagement with the seating surface, the locking member including at least one channel connecting a proximal portion of the chamber to a distal portion of the chamber;

wherein when the sealing portion of the seal member is moved from engagement with the seating surface within the housing, fluid can flow about the sealing member and through the at least one channel to the distal portion of the chamber, wherein the at least one channel includes a plurality of channels positioned about the annular body of the locking member.

7. An IV catheter device comprising:

a housing defining a chamber;

a tubular member extending distally from the housing and defining a lumen, the lumen being in fluid communication with the chamber;

a seal member disposed within the chamber, the seal member having a sealing portion and a septum configured to removably receive an introducer needle, the sealing portion of the seal member being movable into sealing engagement with a portion of the housing; and

a compression member coupled to the seal member, and being configured and dimensioned to apply a compressive force to the septum, the compression member having a substantially cylindrical shape and having an internal surface including at least one friction element, each at least one friction element including an angled, distally extending barb having an apex and a sloped proximal surface, the sloped proximal surface of the barb being configured to facilitate placement of the compression member about the septum and the apex being configured to provide a retention force to retain the compression member about the septum.

8. The IV catheter device according to claim 7, wherein the compression member includes indicia configured to provide an indication that the compression member is properly oriented for placement on the septum.

9. The IV catheter device according to claim 8, wherein the indicia includes one or more cutouts formed on the distal end of the compression member.

10. The IV catheter device according to claim 8, wherein the indicia includes one or more tabs formed on a distal end of the compression member, the one or more tabs further providing an indication that the compression member has been properly positioned on the septum when the distal end of the tabs are positioned flush with a distal face of the septum.

11. An IV catheter device comprising:

a housing defining a chamber;

a tubular member extending distally from the housing and defining a lumen, the lumen being in fluid communication with the chamber;

a seal member disposed within the chamber, the seal member having a sealing portion and a septum configured to removably receive an introducer needle, the sealing portion of the seal member being movable into sealing engagement with a portion of the housing; and

a compression member coupled to the seal member about the septum, the compression member having a substantially cylindrical shape and having an internal surface including at least one friction element, each at least one friction element including an angled, distally extending barb having an apex and a sloped proximal surface, the sloped proximal surface of the barb being configured to facilitate placement of the compression member about the septum and the apex being configured to provide a retention force to retain the compression member about the septum the compression member including indicia configured to provide an indication that the compression member is properly oriented for placement on the septum, the indicia including a plurality of cutouts formed on the distal end of the compression member.

12. An IV catheter device comprising:

a housing defining a chamber;

a tubular member extending distally from the housing and defining a lumen, the lumen being in fluid communication with the chamber;

a seal member disposed within the chamber, the seal member having a sealing portion and a septum configured to removably receive an introducer needle, the sealing portion of the seal member being movable into sealing engagement with a portion of the housing; and

a compression member coupled to the seal member about the septum, the compression member having a substantially cylindrical shape and having an internal surface including at least one friction element, each at least one friction element including an angled, distally extending barb having an apex and a sloped proximal surface, the sloped proximal surface of the barb being configured to facilitate placement of the compression member about the septum and the apex being configured to provide a retention force to retain the compression member about the septum the compression member including indicia configured to provide an indication that the compression member is properly oriented for placement on the septum, the indicia including a plurality of tabs formed on a distal end of the compression member, the one or more tabs further providing an indication that the compression member has been properly positioned on the septum when the distal end of the tabs are positioned flush with a distal face of the septum.
