Abstract
Description
이와 관련하여, 안과용, 국소용, 경구용, 또는 폐용으로 안전하고, 적절하며, 반복적인 투약량(dosages)을 환자에게 전달하는 디바이스가 알려져 있다. 상기 디바이스는 하우징, 상기 하우징 내에 배치되며 일정량의 유체를 수용하는 리저버, 소정의 평균 분사 드랍릿 직경을 갖는 드랍릿들의 스트림을 분사하도록 구성된 이젝터 메커니즘을 포함하고, 상기 드랍릿들의 스트림은, 드랍릿들의 스트림이 사용 동안 환자의 눈에 퇴적하도록 낮은 연행 기류를 갖는다.
또한, 치료 유체를 눈의 표면에 또는 결막 조직에 분사시키는 장치가 알려져 있다. 장치는 압전 액추에이터에 부착되고 이로부터 분리될 수 있는 일회용 살균 약물 앰플을 유리하게 이용하여, 이것에 의해 재충전의 필요성을 제거하고 세균 오염의 가능성을 완화하고 추가 동작에 대해 압전 액추에이터를 재사용하는 비용 효율적인 접근법을 제공한다.
도 2는 도 1의 예의 측면도 및 이의 전자 회로를 예시한다.
도 3은 앰플 및 자기 트랜스듀서를 별도로 도시하는 도 1 및 도 2의 예의 분해도를 예시한다.
도 4는 본 발명의 실시예에서 사용하기에 적합한 구멍 구성의 확대 단면도이다.
도 5a 및 도 5b는 도 4의 구멍 구성의 작동 원리를 개략적으로 도시한다.
Claims (14)
- 환자의 눈에 유체를 전달하기 위한 장치로서,
유체를 유지하도록 구성된 저장조, 구멍, 및 유체가 구멍을 통해 배출되고 있지 않을 때 구멍을 밀봉하도록 구성된 밸브 부재를 포함하는 유체 패키지(fluid package);
