Abstract
Abstract The present invention involves an integrated double-ended needle and blood collection device assembly which is convenient to use, safely contained and ready for disposal after use. The device allows the user to expose and resheath potentially infectious needles without bringing the user's fingers or hands into close proximity with sharp or broken needle tips. After removing the needle from the patient, the needle is safely resheathed by retracting the needle into the device, thereby reducing the risks of accidental needle wounds and infection. The device also serves as a holder for blood collection tubes which can be easily inserted and removed for multiple sampling.
