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.
