Abstract

A hand held hub sterilization and data acquisition device includes a housing having an opening for receiving a medical device, a sterilization chamber formed in the housing, a source of UV radiation disposed within the sterilization chamber for uniform emission of UV-C radiation into the sterilization chamber, and an RFID scanner configured into the housing. A patient care system includes a hand held hub sterilization and data acquisition device and an RFID enabled medical device.

Claims

1. A hand held hub sterilization and data acquisition device comprising:

a housing having an opening for receiving a medical device;

a sterilization chamber formed in the housing;

a source of UV radiation disposed within the sterilization chamber for uniform emission of UV-C radiation into the sterilization chamber;

a user interface; and

an RFID scanner configured into the housing.

2. The device of claim 1, wherein the source of UV radiation is a high voltage tube lamp that produces two ultraviolet wavelengths.

3. The device of claim 1, wherein the source of UV radiation is two UV-C lamps comprising a silica quartz envelope to prevent 190 nm wavelength production and provide minimal attenuation to a 254 nm principal wavelength.

4. The device of claim 3, wherein the sterilization chamber is a silica quartz tube.

5. The device of claim 4, further comprising an aluminum cylinder enclosing the sterilization chamber and providing high reflection efficiency of outward directed UV-C energy.

6. The device of claim 1, wherein the sterilization chamber is a silica quartz tube.

7. The device of claim 1, further comprising an aluminum cylinder enclosing the sterilization chamber and providing high reflection efficiency of outward directed UV-C energy.

8. The device according to claim 1, wherein the housing includes an access door for receiving the medical device into the sterilization chamber.

9. The device according to claim 1, further comprising a safety interlock mechanism.

10. The device of claim 9, wherein the safety interlock mechanism comprises a Hall sensor and a rare earth magnet, and wherein the Hall sensor senses the magnetic field of the magnet when the access door is closed and sends a signal to the user interface indicating a ready state for excitation of the radiation source.

11. The device according to claim 1, further comprising a barcode module.

12. The device according to claim 11, wherein the barcode module utilizes a CMOS 2D imager capable of omnidirectional decoding with regard to code orientation.

13. The device according to claim 1, wherein the medical device is a catheter extension line with a hub and valve assembly.

14. A patient care system comprising:

a hand held hub sterilization and data acquisition device comprising;

a housing having an opening for receiving a medical device;

a sterilization chamber formed in the housing;

a source of UV radiation disposed within the sterilization chamber for uniform emission of UV-C radiation into the sterilization chamber;

a user interface; and

an RFID scanner configured into the housing; and

an RFID enabled medical device.

15. The system according to claim 14, wherein the RFID enabled medical device is a port.

16. The system according to claim 14, further comprising a device charging and download/upload station.

17. The system according to claim 14, further comprising an electronic medical record data interface.
