Means and method of applying RFID and PKI technologies for patient safety
First Claim
1. A method applying RFID (Radio Frequency Identification) and PKI (Public Key Infrastructure) technologies for patient safety, comprising the steps of (a) taking medicines at a pharmacy terminal, wherein the terminal is provided to pharmacists for processing logging into a management system, putting the medicines into a medicine box and then putting the box into an electronic medicine cabinet, collecting changed medicine information of the cabinet through a RFID reader, transmitting data to the management system, giving digital signature, and transmitting the data to store in a database in the management system;
- (b) providing a physician terminal to physicians for logging into the management system, prescribing, giving a medical order, giving digital signature, and confirming the prescription and medical order;
(c) retrieving the medicines at a nurse station terminal, wherein the nurse station terminal is provided to nurses for processing logging in and identity authentication, downloading the prescription and the medical order, and retrieving the prescribed medicine from an electronic medicine chest;
(d) injecting the medicine at the nurse station terminal, wherein a nurse reads/compares patient'"'"'s information, gives the medicine injection to a patient, confirms injection status, uploads information to the management system for storage and computing price, and gives digital signature;
(e) reclaiming empty medicine box at the nurse station terminal, wherein the nurse proceeds logging in and identity authentication, putting the empty medicine box into the electronic medicine chest and closing the empty medicine box, confirming with the third digital signature, and having a next nurse taking over the duty to confirm every empty medicine box is reclaimed;
(f) exchanging the empty medicine box at the pharmacy terminal, further comprising;
staff retrieving medicine bringing the electronic medicine chest to a pharmacy and connecting to the pharmacy terminal;
the pharmacist and the staff logging in and identity authentication;
the pharmacist opening the electronic medicine cabinet for exchanging the medicine and the medicine box;
the pharmacist closing the electronic medicine cabinet and the electronic medicine chest;
the RFID reader on the electronic medicine cabinet collecting changed information of the medicine and confirming the medicine changed and quantity;
uploading data to the pharmacy terminal, the management system matching the changed data, the management system requesting the pharmacist to establish/confirm the relationship between the medicine box and the electronic medicine chest;
the system requesting the pharmacy and the staff giving digital signature for confirming an action of medicine exchange.

Abstract
A system and a method for applying RFID (Radio Frequency Identification) and PKI (Public Key Infrastructure) technologies for patient health safety to install RFID tag and RFID reader on the medicine-storing appliance. By sensing the RFID tag on medicine, the RFID reader stores the medical records such as medicine usage and movement, and transmit to central database. In this way, the circulation of medicine could be controlled, the improper use and distribution of medicines could be avoided, the medical resource management could be improved, and it could ensure that the correct medicine to enhance the process of five rights (right time, right route, right dose, right patient and right drug) and improve the quality of patient safety.
