DETACHABLE BLOOD SEAL.

摘要

A removable blood seal is provided for preventing the leakage of blood during the placement and use of vascular catheters and similar devices. The structure of the blood seal includes a housing having a proximal end and a distal end. The distal end is configured such that a catheter can be removably attached to the distal end. The proximal end is configured such that a needle hub can be fit to the proximal end. The housing includes an internal channel disposed through the housing and configured such that a needle can pass through the channel. An elastomeric seal is placed securely within the channel such that it substantially blocks fluid flow through the channel. The seal is preferably configured of an elastomeric material such that if a needle penetrates said seal and is then later removed, said seal substantially closes the internal channel to fluid flow.
