연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

A medical waste fluid collection and disposal system includes a medical waste fluid collection cart including first and second fluid collection canisters. A valve assembly selectively communicates with the canisters and a valve drive system controls the valve assembly. A liquid level sensor is positioned within each of the canisters. A cart processor communicates with the liquid level sensors and the valve drive system. A cart drain line communicates with the valve assembly and a receptacle, a cart flushing line communicates with the valve assembly and the receptacle and a cart data line and a cart power line communicate with the cart processor and the cart receptacle. A station includes a drain pump that communicates with a drainage system and a station drain line, a flushing pump that communicates with a source of washing liquid and a station flushing line and a station processor in communication with the drain and flushing pumps. A station data line communicates with the station processor. A coupler communicates with the station drain line, flushing line and the station data line and a station power line. The station coupler removably engages the cart receptacle so operation of the cart and station components can be coordinated by the processors for drainage and flushing of the cart canisters.
