| 摘要 |
An integrated blood collection, separation and dispensing device is disclosed which allows a method of blood collection, serum separation and serum dispensing to occur using a single device (other than a centrifuge). The device preferably includes a transfer chamber (64) for receiving separated serum, which has a three-dimensional shape which is reduced in volume and is configured to avoid air entrapment. A dispensing aperture (70) in the transfer chamber (64) fluidly connects the chamber with the atmosphere. Preferably, means (130) are provided adjacent the dispensing aperture (70) for generating a liquid pressure change indication of the presence of liquid advancing towards the dispensing aperture (70). A needle and a protective housing may be optionally provided as an integral part of the device. <IMAGE> |
