Sterilization device
Described herein generally are sterilization devices that can allow sterilization of luminal connection ports. Methods of using these devices are also described.
1. A sterilization device comprising:
a body comprising at least one indicator light, a battery, and a light source; and
an adapter cap consisting of a luer threading, a lens, and a substrate that irreversibly changes color to indicate that sterilization has taken place; and
wherein the adapter cap is inserted into a luminal connection port.
2. The sterilization device of claim 1 , wherein the battery is at least 6 volts.
3. The sterilization device of claim 1 , wherein the indicator lights turn green after the luminal connection port is sterilized.
4. The sterilization device of claim 1 , wherein the light source is a light emitting diode.
5. The sterilization device of claim 1 , wherein the light source emits ultraviolet C light.
6. The sterilization device of claim 1 , wherein the light source has a wavelength of about 275 nm.
7. The sterilization device of claim 1 , wherein the light source has a power of about 30 mW.
8. The sterilization device of claim 1 , wherein the adapter cap is sterile.
9. The sterilization device of claim 1 , wherein the adapter cap is disposable.
10. The sterilization device of claim 1 , wherein the adapter cap is a male luer.
11. The sterilization device of claim 1 , further including a switch, at least one or more sensors, or a multi-sensor to activate the sterilization device.
12. The sterilization device of claim 1 , wherein sterilization occurs in less than about 10 sec.
13. The sterilization device of claim 1 , wherein sterilization occurs in less than about 5 sec.
14. The sterilization device of claim 1 , wherein microbial reduction is a 7-log microbial reduction.
15. The sterilization device of claim 1 , wherein the indicator light turns purple upon the completion of the sterilization of the intravenous connection port.
16. A method of sterilization, the method comprising:
inserting a luminal connection port into a sterilization device comprising at least one indicator light, a battery, a light source, and an adapter cap to apply sterilizing light to the luminal connection port,
wherein the adapter cap consists of a luer threading, a lens, and a substrate;
wherein the device sterilizes a surface of the luminal connection port; and wherein completion of sterilization is indicated by an irreversible color change of the substrate.
17. The method of claim 16 , wherein the sterilizing light is ultraviolet light.
18. The method of claim 17 , wherein the ultraviolet light is ultraviolet C light.
19. The method of claim 18 , wherein the sterilizing light has a wavelength of about 275 nm.
20. The method of claim 16 , wherein the light source is about 3.5 mm×3.5 mm light emitting diode.
21. The method of claim 16 , wherein the sterilizing light is emitted for about 5 seconds.
22. The method of claim 16 , wherein the sterilizing light is emitted for about 5 seconds to about 10 seconds.
23. The method of claim 16 , wherein the indicator light turns green upon the completion of the sterilization of the intravenous connection port.
