Apparatuses for cleaning catheter ports
Methods and apparatus for cleaning a central venous catheter port are disclosed. An apparatus includes a body, a coupling configured to connect the body to the hub, a cleaning cap coupled to the body, and an actuator disposed within the body for rotating and translating the cap relative to the hub. The cleaning cap includes a cap body defining a cavity and a cleaning member disposed within the cavity, the cleaning member having threads that engage with the threads on the hub.
1. A cleaning cap for cleaning a needleless hub of a catheter, the cap comprising:
a cap body defining a cavity and including one or more gaps disposed about a circumference of the cap body, the one or more gaps extending axially from a first end of the cap body; and
a cleaning member disposed within the cavity, the cleaning member having cleaning threads that engage with external threads of the hub;
wherein the one or more gaps are configured to allow outward radial flexing of the cleaning member.
2. The cleaning cap of claim 1 , wherein the cleaning member includes a foam material.
3. The cleaning cap of claim 1 , wherein the cleaning member includes a fabric material.
4. The cleaning cap of claim 1 , wherein the cleaning member includes at least one of a disinfecting substance and an antiseptic fluid.
5. The cleaning cap of claim 1 , wherein the cleaning member is configured to flex radially away from and slide over the external threads of the hub such that the cleaning threads are at least one of slidable, snappable, or jumpable over the external threads of the hub.
6. The cleaning cap of claim 1 , further comprising actuation pins that extend from a bottom surface of the cap body, the actuation pins configured to engage with a cleaning apparatus.
7. The cleaning cap of claim 1 , wherein the cleaning member comprises a cleaning pin configured for intra-valvular cleaning of a valve of a tip of the hub.
8. The cleaning cap of claim 7 , wherein the cleaning pin has a cylindrical shape.
9. The cleaning cap of claim 1 , wherein the cleaning member comprises at least one of a foam, a hydrogel and an alcogel.
10. The cleaning cap of claim 9 , where the at least one of the foam, the hydrogel and the alcogel encapsulates at least one of an alcoholic solution, a radical generating solution, antimicrobial peptides, antimicrobial nanoparticles, and disinfectants.
11. The cleaning cap of claim 9 , wherein the at least one of the foam, the hydrogel and the alcogel encapsulates a self-cleaning solution, the self-cleaning solution having organic oils.
12. The cleaning cap of claim 11 , wherein after the hub is cleaned, the self-cleaning solution is arranged to coat the hub to render it superhydrophobic.
13. The cleaning cap of claim 5 , wherein when the threads of the cleaning member slide, snap, or jump over the external threads of the hub, the cap makes an audible or tactile alert.
14. The cleaning cap of claim 1 , wherein the cap further comprises an indicator to indicate at least one of a wetness or dryness of a cleaning solution in the cap prior to use.
15. The cleaning cap of claim 14 , wherein the indicator is a color indicator arranged to display a color when the cleaning solution in the cap is dry.
16. The cleaning cap of claim 1 , wherein the cleaning threads include at least one of a curved, angled or beveled shape.
17. The cleaning cap of claim 1 , further comprising a cloth disposed over the cleaning threads.
18. The cleaning cap of claim 2 , wherein the foam contains at least one of a cleaning solution and a membrane capsule.
19. The cleaning cap of claim 2 , wherein the foam is disposed along at least a portion of the cavity.
20. The cleaning cap of claim 1 , further comprising a seal to cover the cavity.
21. The cleaning cap of claim 1 , wherein an exterior surface of the cap body includes at least one of a handle or holding feature for manual use.
22. The cleaning cap of claim 4 , wherein the at least one of the disinfecting substance and the antiseptic fluid comprises at least one of aqueous solutions of ethanol, isopropyl alcohol, and hydrogen peroxide, antimicrobial peptides, hypotonic or hypertonic salt solutions, and nanoparticles.
23. The cleaning cap of claim 1 , the cleaning cap containing at least one of a disinfecting substance and an antiseptic fluid comprised of an aqueous alcoholic solution, radical generating solutions, antimicrobial agents, and other disinfectants, and any combination thereof.
24. The cleaning cap of claim 23 , wherein the antimicrobial agents include 0-10% chlorohexidine, antimicrobial peptides, and nanoparticles.
25. The cleaning cap of claim 23 , comprising 70% IPA, 3% H 2 O 2 , and 5% chlorohexidine.
