Medical needle assemblies

A holder for a disposable medical needle assembly, comprising:

• an elongated holder body having a proximal end and a distal end and defining an opening extending from the proximal end to the distal end, with the distal end of the holder body having a needle hub receiving socket, and with the holder body defining an internal rib extending into the opening;
• an ejector rod extending into the opening from the proximal end of the holder body, with the ejector rod slidably received in the holder and having a distal end extending into the holder body and a proximal end extending outward from the holder body;
• a bushing adjacent the distal end of the ejector rod and located on a side of the internal rib facing the distal end of the holder body;
• and
• a spring received about the ejector rod and located on an opposite side of the internal rib from the bushing for biasing the ejector rod outwardly from the holder body.

A medical needle device, comprising:

• a holder having a proximal end and a distal end and defining an opening extending from the proximal end to the distal end, and with the distal end of the holder having a needle hub receiving socket;
• a needle assembly comprising a needle hub and a needle, with the needle hub received in the socket;
• an ejector rod extending into the opening through the proximal end of the holder, with the ejector rod slidably received in the holder and having a distal end configured to engage the needle hub and a proximal end extending outward form the holder;
• a spring received about the ejector rod and located within the holder for biasing the ejector rod outwardly from the holder;
• and
• a button enclosing the distal end of the ejector rod and having a spring-engaging end located within the holder for compressing the spring within the holder,
• wherein movement of the button into the holder causes the distal end of the ejector rod to force the needle hub outward from the socket thereby ejecting the needle assembly from the holder.
