Abstract

Activities of individuals and the movements/usage of products are monitored in an operating room during a surgical procedure by disposing in the operating room a first transceiver operating in a long wavelength mode in which 99.99% or more of radiated energy is in the form of a magnetic field, for example 131 KHz. A distinguishable radio frequency-enabled identification tag is associated with each of a plurality of persons assigned to the surgical procedure, including for example, doctors, nurses, and/or the patient, and optionally with products to be monitored. A signal is transmitted from the first transceiver and responses from the identification tags are monitored. A log is created from the monitored responses indicative activities of each of the persons in the operating room or of movements of tagged products.

Claims

1. A method for monitoring activities in a operating room during a surgical procedure, comprising the steps of

(a) disposing in the operating room a first transceiver operating in a long wavelength mode in which 99.99% or more of radiated energy is in the form of a magnetic field,

(b) associating a distinguishable radio frequency-enabled identification tag with each of a plurality of persons assigned to the surgical procedure;

(c) transmitting a signal from the first transceiver and monitoring responses from the identification tags, and

(d) creating a log from the monitored responses indicative activities of each of the persons in the operating room.

2. The method of claim 1, wherein activities of the persons comprise the presence or absence of a person from the operating room.

3. The method of claim 2, wherein activities of the persons further comprise an indication of the movement of the person within the operating room relative to the first transceiver.

4. The method of claim 1, further comprising the step of disposing in the operating room a second transceiver operating in a long wavelength mode in which 99.99% or more of radiated energy is in the form of a magnetic field at a location different from the first transceiver.

5. The method of claim 4, wherein the first transceiver is disposed in association with a portable cart.

6. The method of claim 5, wherein the second transceiver is disposed in association with the portable at a different position from that of the first transceiver.

7. The method of claim 1, wherein the first transceiver is disposed in association with a portable cart.

8. The method of claim 1, wherein the persons include a doctor and a nurse.

9. The method of claim 8, wherein the persons further include a patient.

10. The method of claim 1, wherein the persons include a patient.

11. The method of claim 1, wherein the magnetic field is adjacent to the first transceiver is from 100 to 800 milligauss.

12. The method of claim 11, wherein the frequency of the first transceiver is 131 KHz.

13. The method of claim 1, wherein the frequency of the first transceiver is 131 KHz.

14. The method of claim 1, further comprising the step of associating an identification tag with an implant or its packaging to be implanted during the surgery, and monitoring the tag associated with the implant and creating a log of concerning movement of the implant or its packaging.

15. The method of claim 1, further comprising the step of associating an identification tag with a physical product used in the operating room and monitoring the tag associated with the physical product and creating a log of concerning movement of the physical product.
