Abstract
A catheter assembly includes an inner needle, a needle hub, a catheter, and a catheter hub. The catheter assembly further includes: a catheter operation member that enables the relative movement of the catheter and the catheter hub with respect to the inner needle; a support member that supports the catheter when the catheter is moved; and a connector that is connected to the catheter hub and is connectable with another medical device. Further, the catheter assembly includes a restriction portion that restricts free displacement of the connector with respect to the catheter hub.
Claims13
A catheter assembly comprising:
- an inner needle;
- a needle hub fixed to a proximal end of the inner needle, the needle hub comprising a housing;
- a catheter including:
- a first lumen through which the inner needle is inserted, and
- a second lumen extending in parallel with the first lumen, the second lumen separated from the first lumen in a direction perpendicular to an axial direction of the first lumen;
- a catheter hub through which the inner needle is inserted and that is located in the housing and fixed to a proximal end of the catheter, the catheter hub being in communication with the first lumen;
- a catheter operation member configured to operate movement of the catheter and the catheter hub with respect to the inner needle;
- a support portion that supports the catheter when the catheter is moved;
- and
- a connector that is connected to the catheter hub and is connectable with another medical device, the connector being in communication with the second lumen;
- wherein:
- an upper side of the connector is covered by the catheter operation member, and a lower side of the connector is covered by the housing, and
- a longitudinal central axis of the connector is co-axial with a longitudinal central axis of the catheter hub.

A catheter assembly comprising:
- an inner needle;
- a needle hub fixed to a proximal end of the inner needle, the needle hub comprising a housing that comprises a side wall;
- a catheter including:
- a first lumen through which the inner needle is inserted, and
- a second lumen extending in parallel with the first lumen, the second lumen separated from the first lumen in a direction perpendicular to an axial direction of the first lumen;
