Abstract
A catheter assembly may include a catheter adapter, which may include a proximal end, a distal end, and a lumen extending between the proximal end and the distal end. The distal end may include a catheter configured to be inserted into vasculature of a patient. The catheter assembly may also include a septum, which may be disposed within the lumen of the catheter adapter. The septum may be secured within the lumen in response to increased pressure by one or more of the following: one or more septum stoppers, a retention disc of a needle assembly, a U-shaped washer, and a conical washer.
Claims8
A catheter assembly, comprising:
- a catheter adapter, comprising a proximal end, a distal end, and a lumen extending therebetween, wherein the distal end comprises a catheter configured to be inserted into vasculature of a patient;
- a septum disposed within the lumen;
- and
- a washer disposed within the lumen and proximal to the septum, wherein the washer has a conical shape and an outer margin, wherein in response to fluid forcing the septum proximally against the conical shape, the conical shape is configured to flatten towards a disc-shape and the outer margin is configured to press against an inner wall of the catheter adapter.
