Declarations under Rule 4.17: as to the identity of the inventor (Rule 4.17(i)) of inventorship (Rule 4.17(iv)) Published: — with international search report (Art. 21(3)) W O 20 17 / 1540 15 Al (54) Title: BROAD SPECTRUM ANTIMICROBIAL & ANTICOAGULANT COMPOSITION (57) : To reduce problems associated with clotting and thrombus formation, it is now common to \"lock\" intravascular ac- cess catheters between successive uses. Locking typically involves first flushing the catheter with saline to remove blood and other substances from the catheter lumen. After the catheter has been flushed, an anti— coagulant solution is injected to displace the saline and fill the lumen. Use of an effective antimicrobial substance along with anticoagulant during the same process is important to re- duce the possibility of bacterial contamination and subsequent infection. The present invention deals with a safe, effective and eco - nomical catheter lock flush solution with excellent antimicrobial and anticoagulant activity. The unique ratio of the active compon - ents of the catheter lock solution used in the invention i.e. Sodium salt(s) of EDTA, Ethanol and D-mannitol with a suitable pH en - sures broad-spectrum antimicrobial and optimum anticoagulant activity.
