Abstract

A combination is disclosed of a handle and a member that is either a phlebotomy device or a drug-injecting syringe. The handle removably attaches by a mating pivot pin and aperture disposed relative to the axis of the handle and the member to ensure that the unlatched configuration is geometrically different from the latched configuration. Latching is achieved by a hook member on one that engages a recessed groove on the other, simply by pivoting the handle until its axis coincides with the axis of the member.

Claims

1. A phlebotomy device comprising a blood collection container having at least one liquid-confining compartment, two opposite ends and a longitudinal axis extending between said ends, one of said ends being a liquid access end constructed to mate with a needle to draw blood into said compartment, and a removable handle on said other end, said handle and said other end including attaching means for removably attaching said handle to said other end by rotation of said handle, said attaching means comprising, as part of said handle or said other end, a mating pin and aperture extending parallel to and displaced from said axis, and latching means for preventing said pin from sliding out of said aperture when said latching means are engaged so that said handle pivots away from said axis when it is unlocked.

2. A removable handle in combination with a member selected from a blood collecting device and a drug-injecting syringe, said device or syringe being provided with a needle for transmission of blood or a drug into or out of the device or syringe, respectively,

said handle and said device or syringe having when assembled a central longitudinal axis,

and further including a pivot pin in either said handle, or said device or syringe, and an aperture in said device or syringe, or handle, respectively, shaped and positioned to frictionally mate with said pin, said pin and said aperture being offset from and extending parallel to said axis,

and further including latching means for latching said handle and said device or syringe together to prevent said pin and said aperture from being axially separated by opposing forces applied along said axis.

4. A combination as defined in claim 2 or 3, wherein said latching means comprise a hook on one of said member and said handle and latch groove on the other of said member and said handle to receive said latch in a temporary locked configuration, said latch and groove when engaged preventing translation separation of said handle from said member.

3. A removable handle in combination with a member comprising a phlebotomy tube, said handle and tube having when assembled a central longitudinal axis,

and further including a pivot pin in one of said tube and said handle, and an aperture in the other of said tube and said handle to frictionally mate with said pin, said pin and said aperture being offset from and extending parallel to said axis,

and further including latching means for latching said handle and said member together to prevent said pin and said aperture from being axially separated by opposing forces applied along said axis.
