Abstract

The present invention relates to a fluid injection needle unit having a function of preventing needlestick injury and infection wherein a cover, a needle body and a body are improved in shape, and after the needle body is inserted into a blood vessel of a patient, the cover is coupled to the bottom end periphery of the body and the needle body is detached from the body by means of detachable mounting members, so that a needle and the needle body are inserted unitarily into the cover to prevent the occurrence of the needlestick injury and infection.

Claims

1. A fluid injection needle unit having a function of preventing needlestick injury and infection, comprising:

a needle film adapted to be inserted into a blood vessel of a patient and having an injection hole formed along the interior thereof;

a body having an insertion hole formed to pass through the top and bottom thereof, a top end locking projection formed along the outer top end periphery thereof, and a bottom end locking projection formed along the outer bottom end periphery thereof;

a needle body fixed to the insertion hole of the body by means of detachable mounting members before the needle film is inserted into the blood vessel of the patient and detached from the insertion hole of the body after the needle film is inserted into the blood vessel of the patient;

a needle fixedly protruding from the top of the body in such a manner as to be inserted into the injection hole of the needle film before the needle film is inserted into the blood vessel of the patient; and

a cover having an internal space closed on top thereof and open on bottom thereof and fixedly mounted onto the top end locking projection of the body before the needle film is inserted into the blood vessel of the patient and fixedly mounted onto the bottom end locking projection of the body after the needle film is inserted into the blood vessel of the patient.

2. The fluid injection needle unit according to claim 1, wherein so as to allow the needle film to be inserted into the blood vessel of the patient, the needle and the needle film are inserted into the blood vessel of the patient after the cover is detached from the body, the needle film is detached from the needle in the state of being inserted into the blood vessel of the patient, the cover is fixedly mounted onto the bottom end locking projection of the body, and the needle body is detached from the body by means of the detachable mounting members, so that the needle body and the needle are accommodated into the cover.

3. The fluid injection needle unit according to claim 1, wherein the detachable mounting members comprise a mounting protrusion formed along the outer peripheral surface of the needle body and a locking groove formed along the inner peripheral surface of the insertion hole of the body.

4. A fluid injection needle unit having a function of preventing needlestick injury and infection, comprising:

a needle film adapted to be inserted into a blood vessel of a patient and having an expanded tube formed on the lower end periphery thereof and an injection hole formed along the interior thereof;

a body having an insertion hole formed to pass through the top and bottom thereof, a top end locking projection formed along the outer top end periphery thereof, a bottom end locking projection formed along the outer bottom end periphery thereof, and an insertion member formed on top thereof;

a needle body inserted into the insertion member of the body and fixed thereto by means of the expanded tube of the needle film before the needle film is inserted into the blood vessel of the patient and detached from the insertion member of the body after the needle film is inserted into the blood vessel of the patient;

a needle fixedly protruding from the top of the body in such a manner as to be inserted into the injection hole of the needle film before the needle film is inserted into the blood vessel of the patient; and

a cover having an internal space closed on top thereof and open on bottom thereof and fixedly mounted onto the top end locking projection of the body before the needle film is inserted into the blood vessel of the patient and fixedly mounted onto the bottom end locking projection of the body after the needle film is inserted into the blood vessel of the patient.

5. The fluid injection needle unit according to claim 4, wherein so as to allow the needle film to be inserted into the blood vessel of the patient, the needle and the needle film are inserted into the blood vessel of the patient after the cover is detached from the body, the needle film is detached from the needle in the state of being inserted into the blood vessel of the patient, the cover is fixedly mounted onto the bottom end locking projection of the body, and the needle body is detached from the insertion member by means of the detaching of the needle film, so that the needle body and the needle are accommodated into the cover.
