Passive safety I.V. blood collection catheter

摘要

Apparatus and methods for a single, handheld device that provides for both insertion of a catheter and collection of a fluid. Some embodiments further include a needle that assists in the insertion of the catheter into a blood vessel, and which includes a retraction feature that protects the user from an accidental needle stick when the device is ready for disposal. Still further embodiments include a protective cover that prevents a user from accidentally being stuck by a second needle used for the introduction of the patient's blood into a collection device.

主权项

1. An apparatus for collecting blood in a container and connecting to intravenous tubing, comprising:
a main body defining an interior including a collection cavity adapted and configured to receive therein an end of a readily separable container; a first retractable hollow needle having a first sharp tip, said first needle being movable from a first extended position in which the first sharp tip is exterior to said main body for insertion into a blood vessel to a second retracted position in which the first sharp tip is within the interior; a second hollow needle attached to said main body and having a second sharp tip extending into the collection cavity; and a catheter assembly having a body and a hollow lumen and receiving said first needle within the lumen, the first sharp tip extending from the distal end of the lumen; wherein said first needle and said main body are readily separable from said catheter assembly; and a flexible tube adapted and configured to provide a fluid flowpath from said first needle to said second needle; and a gas purging valve that permits the escape of gas contained in the fluid flowpath from said first needle to said second needle.
