摘要： A retractable safety needle assembly is provided. The needle assembly includes a tubular outer body, a retraction assembly contained with the outer body and a biasing element for applying a retraction force therebetween. The retraction assembly includes a cannula having an intravenous puncture tip and a non-patient puncture tip at opposing ends. In a first position, the intravenous puncture tip extends from a first end of the tubular outer body. The retraction assembly is adapted for movement within the tubular outer body from the first position to a second position in which the intravenous puncture tip and the non-patient puncture tip are contained entirely within the tubular outer body and are offset from a general axis defining the outer body.

摘要： A medical device is provided for collecting fluid samples from a patient, such as blood samples. The device includes a needle having a forward sharpened tip that is retracted into the housing of the device after use to prevent exposure to the contaminated needle. The rearward end of the housing is open, forming a socket for receiving a fluid container, such as a vacuum tube, that will receive the fluid sample. A needle retainer releasably retains the needle in the extended position against the rearward bias of a biasing element. After use, the medical professional retracts the needle by pressing an actuation button, allowing the biasing element to displace the needle rearwardly. A guide track guides the needle during retraction, tilting the needle off-axis.
