Abstract

An intravenous catheter system having a retractable needle system and a body system is disclosed. The retractable needle system includes a housing, a needle, a docking feature, and an optional anti-shearing mechanism. The body system includes a body, at least one hub, a catheter connector, at least one plug, a plug recoil mechanism, a locking mechanism, a flash chamber, and a flash window.

Claims

1. An intravenous catheter system, comprising:

an elongated hollow body forming an internal volume;

a hub rigidly attached to an end of the body;

a plug configured to engage with the hub and configured to create a seal between the hub and the internal volume, the plug being operable between a first position for use with needle-type and blunt-type devices and a second position for use with needleless devices;

a first fluid channel, formed along an outer surface of the plug; and

a second fluid channel, formed along an internal surface of the elongated hollow body, the second fluid channel being associated with the first fluid channel;

wherein the plug is comprised of elastomeric material having a pre-formed cylindrical hole through a length of the plug the preformed hole having a constant diameter along the entire length of the plug;

wherein the plug is adapted to sealingly receive the needle-type and blunt-type devices while in the first position and sealingly receive the needleless devices while in the second position;

wherein, when the plug is in the second position, the first fluid channel and the second fluid channel connect to form a flow-through channel between the plug and the elongated hollow body; and

wherein, when the plug is not in the second position, the first fluid channel and the second fluid channel are separate and do not connect to form the flow-through channel.

2. The intravenous catheter system according to claim 1, further comprising:

a recoil means for biasing the plug into the first position.

3. The intravenous catheter system according to claim 2, wherein the recoil means is disposed within the body.

4. The intravenous catheter system according to claim 2, wherein the recoil means is disposed within the hub.

5. The intravenous catheter system according to claim 2, wherein the recoil means is disposed partially within the body and partially within the hub.

6. The intravenous catheter system according to claim 1, further comprising:

at least one additional hub in fluid communication with the body; and

an additional plug for providing a seal between each additional hub and the internal volume, each additional plug being operable between a first position for use with needle-type and blunt-type devices, and a second position for use with needleless devices;

wherein each additional plug is adapted to sealingly receive the needle-type and blunt-type devices while in the first position, and sealingly receive the needless devices while in the second position.

7. The intravenous catheter system according to claim 1, further comprising:

an intravenous needle extending through the plug and the internal volume.

8. The intravenous catheter system according to claim 1, further comprising:

a locking means for selectively limiting movement of the plug relative to the hub.
