Abstract

A sanitization compliance monitoring system comprises care giver badges, patient bed beacons associated with patient beds, dispenser beacons associated with sanitization dispensers, and a central unit for wirelessly communicating with the badges.

Claims

1. A sanitization compliance monitoring system for a health care environment having patient beds, comprising:

badges wearable by persons, said badges having indicia representing a first-state indicating a sanitary compliant condition of the person, and a second-state representing an unsanitary state indicating the person'"'"'s contact with a second patient after contact with, and different from, a first patient, said badges also having a wireless transmitter/receiver for communicating an identification signal unique to a single badge, and the current state of the badge;

patient bed beacons, each associated with a different respective patient bed, each bed beacon capable of wirelessly communicating with said badges;

dispenser beacons, each associated with a sanitization dispenser, and having a transmitter/receiver capable of wirelessly communicating with said badges; and

wherein a dispenser beacon causes a badge to change from the second-state to the first-state when the person has performed a sanitization procedure at a sanitization dispenser, and

wherein a badge in a first-state changes to said second-state when located in a certain proximity to a second patient bed beacon different from a first patient bed beacon at which the user was previously located without having performed a sanitization procedure at a dispenser during movement between the respective beds associated with the first and second patient beds, and transmits a status signal indicating such badge state change to the patient bed beacon with the badge identification signal.

2. A sanitization compliance monitoring system for a health care environment having patient beds, comprising:

badges wearable by persons, said badges having indicia representing a first-state indicating a sanitary compliant condition of the person, a second-state representing a cautionary state indicating the person'"'"'s contact with a first patient, and a third-state representing an unsanitary state indicating the person'"'"'s contact with a second patient after contact with, and different from, a first patient, said badges also having a wireless transmitter/receiver for communicating an identification signal unique to a single badge, and the current state of the badge;

patient bed beacons, each associated with a different respective patient bed, each bed beacon capable of wirelessly communicating with said badges;

dispenser beacons, each associated with a sanitization dispenser, and having a transmitter/receiver capable of wirelessly communicating with said badges; and

wherein a badge in said second-state changes to said third-state when located in a certain proximity to a patient bed beacon different from the patient bed beacon which caused the badge to change from the first-state to the second-state, and transmits a status signal indicating such second-to-third-state change to the patient bed beacon with the badge identification signal, and

wherein a dispenser beacon causes a badge to change from the second-state or third-state to the first-state when the person has performed a sanitization procedure at a sanitization dispenser beacon.

3. A method for monitoring sanitization compliance for a health care environment having patient beds, comprising:

providing patient bed beacons, each associated with a different respective patient bed, each bed beacon capable of wirelessly communicating with said badges;

providing dispenser beacons, each associated with a sanitization dispenser, and having a transmitter/receiver capable of wirelessly communicating with said badges;

changing the state of a badge from said first-state changes to said second-state when located in a certain proximity to a patient bed beacon, and transmitting a status change signal indicating such first-to-second-state change to the patient bed beacon with the badge identification signal;

changing the state of a badge from said second-state changes to said third-state when located in a certain proximity to a patient bed beacon different from the patient bed beacon which caused the badge to change from the first-state to the second-state, and transmitting a status signal indicating such second-to-third-state change to the patient bed beacon with the badge identification signal; and

changing the status of a badge from the second-state or third-state to the first-state when the person has performed a sanitization procedure at a sanitization dispenser beacon.

4. A sanitization compliance monitoring system for a health care environment having patient beds, comprising:

badges wearable by persons, said badges having indicia representing a first-state indicating a sanitary compliant condition of the person, and a second-state representing an unsanitary state indicating the person'"'"'s contact with a second patient after contact with, and different from, a first patient, said badges also having a wireless transmitter/receiver for communicating an identification signal unique to a single badge, and the current state of the badge;

patient bed beacons, each associated with a different respective patient bed, each bed beacon capable of wirelessly communicating with said badges;

dispenser beacons, each associated with a sanitization dispenser, and having a transmitter/receiver capable of wirelessly communicating with said badges; and

wherein a dispenser beacon causes a badge to change from the second-state to the first-state when the person has performed a sanitization procedure at a sanitization dispenser, and

wherein a badge in a first-state changes to said second-state when located in a certain proximity to a second patient bed beacon different from a first patient bed beacon at which the user was previously located without having performed a sanitization procedure at a dispenser during movement between the respective beds associated with the first and second patient beds, and transmits a status signal indicating such badge state change to the patient bed beacon with the badge identification signal.

5. A sanitization compliance monitoring system for a health care environment having patient beds, comprising:

badges wearable by persons, said badges having indicia representing a first-state indicating a sanitary compliant condition of the badge-wearer, and a second-state representing an unsanitary state indicating the badge-wearer'"'"'s contact with a second patient after contact with, and different from, a first patient, said badges also having a wireless transmitter/receiver for communicating an identification signal unique to a single badge, and the current state of the badge;

patient bed beacons, each associated with a different respective patient bed, each bed beacon capable of wirelessly communicating with said badges;
