  • Moment 3 If the healthcare worker washes their hands within the patient zone using the personal dispenser they may be credited with a moment 3 hand wash. In another embodiment they could register the hand wash as a moment 3 hand wash via the input device / sensor switch of the PDU.
  • Moments 4 and 5 As a healthcare worker leaves a patient zone, the system determines if the healthcare worker washes their hands. If they do wash their hands they are compliant with moment 4 and moment 5. If they do not wash their hands they are not compliant with moment 4 and 5. In another embodiment they could register the hand wash as a moment 4 or moment 5 hand wash via the input device / sensor switch of the PDU.

For example, if the HCW is performing a type 2 moment inside the patient zone, they may depress the button twice in quick succession.
  • the transmitter in the PDU is further operable to transmit this data back to the CMU so that the CMU can store in memory the type of dispensing event that was performed by the HCW.

Abstract

L'invention concerne un système, un procédé et une unité de distribution personnelle (PDU) permettant de surveiller le respect des règles d'hygiène des mains. En particulier, l'invention permet de surveiller le respect des directives de l'Organisation mondiale de la santé (WHO) sur le lavage des mains d'un travailleur de la santé (HCW) dans un établissement de soins. L'établissement de soins comprend une pluralité de capteurs désignant des zones au sein de l'établissement de soins comme zones de soins de santé et zones de patients. Le HCW porte sur lui une PDU d'un composé de lavage des mains ainsi qu'un dispositif de suivi. La PDU transmet une indication d'un événement de distribution à chaque fois que la PDU est utilisée. Une unité centrale de surveillance (CMU) reçoit les indications des événements de distribution ainsi que l'emplacement du HCW dans l'établissement de soins au fil du temps puis détermine le type de lavage des mains qui a été effectué. Dans un mode de réalisation, la PDU est équipée d'un dispositif d'entrée pour permettre au HCTW d'indiquer le type de lavage des mains en cours de réalisation.
