Abstract

A radio frequency identification wristband for attaching to a patient that has a band, a wristband housing attached to or integral with said band, one or more radio frequency identification tag(s) or tag inlay(s), an insulator material, wherein said wristband housing is adhered to said radio frequency identification tag or tag inlay, said radio frequency identification tag or tag inlay is adhered to an isolator material, and wherein said insulator material is nearest to the skin of the patient and insulates the radio frequency identification tag or tag inlay from the patient'"'"'s skin.

Claims

1. A radio frequency identification wristband comprising:

a band;

a wristband housing attached to or integral with said band; and

two or more radio frequency identification battery-assisted-passive (BAP) tag inlays, wherein each radio frequency identification BAP tag inlay comprises a radio frequency identification tag integrated circuit and an antenna;

wherein said wristband housing is adhered to at least one of the two or more radio frequency identification BAP tag inlays,

wherein at least one of the two or more radio frequency identification BAP tag inlays is adhered to a foam having a low dielectric constant, a dimpled surface, and a water absorption of less than or equal to 0.04 lbs/cut surface,

wherein said foam insulates the at least one radio frequency identification BAP tag inlay from the skin of a patient, and

wherein each of the two or more radio frequency identification BAP tag inlays is configured to communicate an identifier.

2. The radio frequency identification wristband of claim 1, wherein the at least one radio frequency identification BAP tag inlay is adhered to the foam using a medical grade adhesive.

3. The radio frequency identification wristband of claim 1, further comprising a visual identity label.

4. The radio frequency identification wristband of claim 1, wherein when the radio frequency identification wristband is worn by a patient, said foam is nearer to the skin of the patient than any of the two or more radio frequency identification BAP tag inlays.

5. The radio frequency identification wristband of claim 1, wherein said foam is a latex free material.

6. The radio frequency identification wristband of claim 1, wherein said foam is hypoallergenic.

7. The radio frequency identification wristband of claim 1, wherein the at least one radio frequency identification BAP tag inlay and said foam are laminated.

8. The radio frequency identification wristband of claim 1, wherein the at least one radio frequency identification BAP tag inlays and said foam are non-laminated and said foam is hydrophobic.

9. The radio frequency identification wristband of claim 1, wherein said band comprises a clasp on one end and comprises one or more holes on an opposite end for receiving said clasp.

10. The radio frequency identification wristband of claim 1, wherein said wristband is capable of being affixed to an ankle.

11. The radio frequency identification wristband of claim 9, wherein said housing is located between said clasp and said opposite end.

12. The radio frequency identification wristband of claim 1, wherein the identifier is a 96-bit identifier.

13. The radio frequency identification wristband of claim 1, wherein each of the two or more radio frequency identification BAP tag inlays comprises a user memory for storing information.

14. The radio frequency identification wristband of claim 1, wherein the foam is hydrophilic.

15. The radio frequency identification wristband of claim 1, wherein each of the two or more radio frequency BAP tag inlays comprises a radio frequency identification tag integrated circuit, an antenna, a substrate, and a battery.

16. The radio frequency identification wristband of claim 1, wherein each of the two or more radio frequency identification BAP tag inlays is configured to communicate a different identifier than the other ones of the two or more radio frequency identification BAP tag inlays.
