Abstract

A captive cover for a hypodermic needle of an IV tube assembly has an elongated body connected to an element of the IV tube assembly. The elongated body is hollow and has a proximal opening, a closed distal end, a chamber, at least one locking tab and one or more optional connectors. The hypodermic needle of the IV tube assembly can be inserted through the proximal opening into the chamber. A flange on the hypodermic needle of the IV tube assembly is held in the captive cover by the locking tab. Since the hypodermic needle of the IV tube assembly only passes through the locking tab of the elongated body, the hypodermic needle of the IV tube assembly can be conveniently inserted into the elongated body. The captive cover can accommodate an ordinary hypodermic needle and has a simple structure.

Claims

1. A captive cover for a hypodermic needle of an intravenous (IV) tube assembly with multiple elements including a container needle, an upper tube, a lower tube and a flow control apparatus, the captive cover comprising an elongated body adapted to be attached longitudinally to an element of the IV tube assembly, wherein

the elongated body is hollow and has

an outside surface

a proximal opening tapered inward;

a closed distal end;

a chamber formed longitudinally in the elongated body between the proximal opening and the closed distal end, communicates with the tapered proximal opening and tapers slightly toward the closed distal end; and

at least one resilient locking tab formed in the outside surface near the proximal opening and protrudes into the chamber toward the distal end.

2. The captive cover as claimed in claim 1, wherein the elongated body has one locking tab.

3. The captive cover as claimed in claim 1 further comprising at least one connector formed integrally with and extending radially from the outside surface of the elongated body to connect to an element of the IV tube assembly.

4. The captive cover as claimed in claim 3, wherein the captive cover has two connectors formed integrally with and extending radially from respectively the distal end and near the proximal opening of the elongated body.

5. The captive cover as claimed in claim 4, wherein each connector is a C-shaped clip.
