연합인증

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

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A high frequency ventilator which generates a high frequency pressure wave in a supply of ventilating gas for supporting ventilation in air breathing animals. The high frequency pressure wave causes the ventilating gas to be exchanged and to diffuse through the animal\s lungs fast enough to support ventilation without spontaneous breathing on the part of the animal and without the aid of a separate ventilator.

대표
청구항

An apparatus for supporting full ventilation in an air breathing animal comprising: means for supplying a respirating gas to an animal at elevated pressure, a linear motor, a diaphragm driven by said linear motor, and circuit means for producing a high frequency, variable frequency, variable amplitude signal for driving said linear motor to drive said diaphragm to generate a pressure wave in said gas which is polar relative to the static pressure in an airway of said animal, said pressure wave having a positively sloped portion forcing gas into said airw...
