pivotally mounted or connected to a portion of the needle member;

movably mounted to a portion of the needle member;

movable from a position not covering a proximal needle of the needle member to a position covering the proximal needle; and

movable from an initial position to a locking position covering the proximal needle.

11. The device of claim 1 , wherein the body is a one-piece member.

12. The device of claim 1 , further comprising guide projections arranged on the front end of the body.

13. The device of claim 1 , wherein the front end comprises a through opening sized to receive an inner needle end of the needle member.

14. The device of claim 1 , wherein the rear end comprises a flange.

15. The device of claim 1 , further comprising a locking mechanism that prevents the needle member from being reinstalled on the body.

16. The device of claim 1 , further comprising a mechanism for preventing re-use of the device.

17. The device of claim 1 , further comprising a mechanism for rendering the device single-use.

18. A method of taking a fluid sample using the device of claim 1 , the method comprising:

installing the needle member;

inserting a receptacle into the device;

removing the receptacle from the device; and

moving a safety cover to a needle covering position after use.

19. A method of taking a fluid sample using the device of claim 1 , the method comprising:

inserting a receptacle into the body;

removing the receptacle from the body; and

moving a safety cover to a needle covering position.

20. A method of taking a fluid sample using the device of claim 1 , the method comprising:

inserting a receptacle into the main hollow section;

removing the receptacle; and

preventing re-use of the device.

21. A fluid collection device comprising:

a body having a front end, a back end, and a main hollow section arranged between the front and back ends;

a needle hub securing section arranged on the front end and being structured and arranged to receive therein a needle member;

the fluid collection device is structured and arranged to utilize at least an installation mode, an operational mode, and a post-use mode;

in the installation mode, the needle member being coupled to the body via the needle hub securing section;

in the operational mode, fluid passing through the needle member and into a receptacle inserted into the main hollow section; and

in the post-use mode, a safety cover at least one of:

prevents removal of the needle member from the fluid collection device;

prevents removal of the needle member from the needle hub securing section;

activates release of the needle member from the body such that when the safety cover is in a position covering a needle of the needle member, the needle member can fall out of the needle hub securing section;

activates release of the needle member from the body such that when the safety cover is in a position covering a needle of the needle member, the needle member is no longer securely retained to the needle hub securing section;

releases a securing engagement between the needle member and the needle hub securing section;

unlocks a locking connection between the needle member and the needle hub securing section; and

moves a mechanism arranged in an area of the needle hub securing section which releases a connection between the needle member and the needle hub securing section.

22.
