ABSTRACT:
A catheter plug for sealing the proximal end of a parenterally placed catheter and permitting repeated small volume injections and delivery of parenteral fluids without disturbing the sterility of the catheter. The catheter plug has a compression chamber for applying compression to a self-sealing elastometric septum thereby enhancing the septum's self-sealing characteristics. Compression force is applied to the septum by screw movement between oppositely threaded male and female couplers. The catheter plug is particularly useful in situations where pressures higher than arterial pressures are encountered or where it is desirable to leave the catheter indwelling for long periods of time.
