Abstract

Hand hygiene apparatuses and methods for monitoring hand hygiene and for dispensing hand soap or hand sanitizers. An illustrative hand hygiene apparatus includes a computer, a database stored on the computer, a biometric sensor operatively coupled to the computer, a hand hygiene dispenser operatively coupled to the computer, and a hand soap or hand sanitizer disposed adjacent to the hand hygiene dispenser. The database might include a collection of partial biometric data for a group of persons. An illustrative method may include collecting a set of partial biometric data, providing a biometric sensing apparatus and a hand hygiene dispenser coupled to the biometric sensing apparatus, sensing biometric data from a first individual from the group of persons with the biometric sensing apparatus, identifying the first individual by comparing the sensed biometric data with the set of partial biometric data, and dispensing a hand soap or hand sanitizer from the hand hygiene dispenser onto the hands of the first individual.

Claims

1. A method for monitoring hand hygiene and for dispensing hand soap or hand sanitizers, comprising the steps of:

collecting a set of partial biometric data from a group of persons, the set of partial biometric data being sufficient to distinguish each individual within the group of persons but being substantially insufficient to distinguish a pool of people outside of the group of persons;

sensing biometric data from a first individual from the group of persons with a biometric sensing apparatus coupled to a hand hygiene dispenser;

identifying the first individual by comparing the sensed biometric data from the first individual with the set of partial biometric data; and

dispensing a hand soap or hand sanitizer from the hand hygiene dispenser onto the hands of the first individual;

wherein the step of collecting a set of partial biometric data from a group of persons comprises;

creating a database for storing a set of templates;

for each individual from the group of persons, performing the steps of, extracting an at least one characteristic data point from the individual;

creating a template associating the at least one characteristic data point with the individual;

comparing the template to the set of templates in the database;

extracting a subsequent characteristic data point from the individual only if the template is not unique to the set of templates;

storing the template in the database.

2. The method of claim 1, wherein the step of sensing biometric data from a first individual from the group of persons with the biometric sensing apparatus includes sensing fingerprint data.

3. The method of claim 1, further comprising the step of creating a record of the dispensing step.

4. The method of claim 3, wherein the record includes a record of the date and time for the dispensing step.

5. The method of claim 3, further comprising the step of creating one or more additional records of additional dispensing steps.

6. The method of claim 5, further comprising the step of compiling a log listing all of the records.
