Abstract
A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending therethrough. The catheter assembly may also include a septum slidably disposed within the lumen. The septum may include a distal end, a proximal end, and a barrier disposed between the distal end of the septum and the proximal end of the septum. The barrier may divide an interior of the septum into a distal cavity and a proximal cavity. A distal face of the barrier may include a protrusion. The barrier may include a slit extending through the protrusion for selectively opening fluid communication between the distal cavity and the proximal cavity.
Claims20
A catheter assembly, comprising:
- a catheter adapter comprising a distal end, a proximal end, and a lumen extending therethrough;
- and
- a septum slidably disposed within the lumen, the septum comprising a distal end, a proximal end, and a barrier disposed between the distal end of the septum and the proximal end of the septum, wherein the barrier divides an interior of the septum into a distal cavity and a proximal cavity, wherein a distal face of the barrier comprises a protrusion, wherein the barrier comprises a slit extending through the protrusion for selectively opening fluid communication between the distal cavity and the proximal cavity.
A catheter assembly, comprising:
- a catheter adapter comprising a distal end, a proximal end, and a lumen extending therethrough;
- a septum actuator fixed within the lumen of the catheter adapter;
- a septum slidably disposed within the lumen, the septum comprising a distal end, a proximal end, a barrier disposed between the distal end of the septum and the proximal end of the septum, and a slit disposed within the barrier for selectively opening fluid communication between the distal cavity and the proximal cavity, wherein the barrier divides an interior of the septum into a distal cavity and a proximal cavity, wherein a distal face of the barrier comprises a protrusion, wherein the septum is configured to move between a proximal position and a distal position in response to insertion of a separate device into the proximal end of the catheter adapter, wherein the slit extends through a center of the protrusion such that the septum actuator is disposed within the center of the protrusion when the septum is disposed in the distal position.
