Fluid flow control device for use with an evacuated blood collection container

摘要

A fluid flow control device for use with an evacuated blood collection container comprises a substantially rigid body. Two needle cannulae are connected to the body with a space therebetween. A resilient, collapsible passage member lies in the space and connects the two cannulae in fluid communication with each other. The passage member contacts the body only at its ends with its central portion positioned to remain free of contact with the body during use. This passage member is accessible to finger grip from at least two different directions to allow an operator of the device to apply pressure with the fingers to control fluid flow through the passage member. Another embodiment of the present invention substantially as described above includes an operable collapsing element connected to the body for collapsing the passage member during use to control fluid flow therethrough.
