Medical assembly
First Claim
1. A holder for supporting a needle assembly for use in a blood collection procedure comprising:
- a hollow holder body having a generally open proximal end and a partially enclosed distal end, with the distal end of the holder body defining an opening communicating with the interior of the holder body; and
a one-way rotatable collar in rotational communication with the opening in the holder body and including a needle assembly receiving socket for receiving a needle assembly for connection with the holder body;
wherein the collar is configured to co-act with the interior of the holder body such that the collar can rotate in only one direction relative to the holder body when a needle assembly is received in the socket.

Abstract
A medical needle device includes a needle assembly, a hollow needle assembly holder, and a one-way rotational collar. The needle assembly includes a needle hub supporting a needle. The needle hub has a proximal end and a distal end. The hollow needle assembly holder has a proximal end and a distal end. The distal end of the holder defines an opening communicating with the interior of the holder. The one-way rotational collar is rotatably received in the opening in the holder for connecting the needle assembly to the holder. The collar defines a needle assembly receiving socket. The proximal end of the needle hub is received in the socket. The collar is configured to co-act with the interior of the holder such that the collar and needle assembly can rotate in only one direction relative to the holder.

25. A holder for use with a medical needle assembly including a needle hub and a needle, comprising:
-
a hollow holder body having a proximal end and a distal end, with the distal end defining an opening communicating with the interior of the holder; a one-way rotatable collar in rotational communication with the opening in the holder body for connecting the needle assembly to the holder body, with the collar defined by a first disc portion rotatably received in the opening in the holder body and a second disc portion extending into the interior of the holder body, with the collar defining a needle assembly receiving socket; wherein the second disc portion of the collar is configured to co-act with the interior of the holder body such that the collar can rotate in only one direction relative to the holder body. - View Dependent Claims (26, 27)

28. A method of using a medical needle device in a blood collection procedure, comprising the steps of:
-
(a) providing a medical needle assembly including an externally threaded needle hub and a needle supported by the hub; (b) providing a holder for the needle assembly including a hollow holder body having an end defining an opening communicating with the interior of the holder, and a one-way rotatable collar in rotational communication with the opening in the holder body, the collar including an internally threaded needle hub receiving socket; (c) threading the needle hub into the socket of the collar in one rotational direction; and (d) preventing the needle hub from being unthreaded from the socket once fully threaded into the socket in the collar. - View Dependent Claims (29, 30, 31, 32)

33. A holder assembly for receiving a medical needle supported by a hub and for guiding a collection container into piercable engagement with the needle, the holder assembly comprising:
-
a hollow body comprising a tubular wall extending along an axis between an open end for receiving a collection container and a partially enclosed end, the hollow body including at least one tooth extending from the tubular wall; and a selectively rotatable needle mount engaged with the partially enclosed end of the body and comprising a bore with an internal thread spiraling in a first direction about the axis, the rotatable needle mount including at least one tooth for interference engagement with the at least one tooth of the hollow body when the needle mount is rotated in the first direction, the interference engagement causing sufficient resistance for a hub supporting a needle to be threaded with the internal thread of the needle mount, the interference engagement being insufficient to cause unthreading of a hub threaded with the internal thread of the needle mount when the needle mount is rotated in a direction opposite the first direction.

34. A medical needle device, comprising:
-
a needle assembly including a needle hub supporting a needle, with the needle hub having a proximal end and a distal end; a hollow needle assembly holder having a proximal end and a distal end, with the distal end of the holder defining an opening communicating with the interior of the holder; and a one-way rotatable collar in rotational communication with the opening in the holder for connecting the needle assembly to the holder, with the collar defining a needle assembly receiving socket, and with the proximal end of the needle hub received in the socket; wherein the collar is configured to co-act with the interior of the holder such that the collar and needle assembly can rotate in only one direction relative to the holder. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
