Methods for disinfecting medical connectors
View Patent ↗Caps can be used to cover and sterilize the male luer of a medical connector. Some caps can create a seal with the male luer to prevent antiseptic from entering a lumen of the male luer. A biasing element can aid in creating or maintaining the seal.
1. A method of disinfecting a male luer connector of the type including a post having a lumen through which fluid flows, the method comprising:
providing a male-disinfecting cap including
a receiving portion having a sidewall defining a chamber into which the post of the male luer connector can be received;
a biasing member disposed in the chamber;
a sealing member disposed in the chamber; and
an antiseptic agent disposed in the chamber; and
moving the cap in relation to the male luer connector so that (i) the post is received into the chamber, (ii) the biasing member urges the sealing member toward the post to cover the lumen and maintain the sealing member against the lumen, and, (iii) while the sealing member covers the lumen so as to inhibit at least the antiseptic agent from entering the lumen, at least a portion of the antiseptic agent is caused to come into contact with the post.
2. A method according to claim 1 , wherein the sealing member is configured to permit the flow of the antiseptic agent past the sealing member to the post.
3. A method according to claim 2 , wherein the sealing member includes at least one channel near its periphery.
4. A method according to claim 1 , further comprising providing a pad disposed in the chamber abutting the sealing member, the pad containing the antiseptic.
5. A method according to claim 1 , further comprising providing a cover disposed over an opening of the chamber.
6. A method according to claim 5 , wherein the cover comprises an impervious pliable material.
7. A method according to claim 6 , wherein the impervious pliable material is a foil.
8. A method according to claim 1 , wherein a portion of the sidewall of the receiving portion has a taper that narrows toward an interior of the chamber.
9. A method according to claim 8 , wherein the taper is near an opening of the chamber.
10. A method according to claim 8 , further comprising engaging the post against the taper of the sidewall.
