Abstract

A method of using a safety enclosure for a needle, the needle including an aft end and a fore end together forming a right angle, the fore end including a sharp outer end. The method includes providing a safety enclosure including a needle housing and a panel unit, the needle housing having a finger pad, orienting the safety enclosure in a desired location for insertion of the needle, and applying pressure to the finger pad sufficient to cause penetration of the needle at the desired location and to move the panel unit to the installation position.

Claims

1. A method of using a safety enclosure for a needle, the needle including an aft end and a fore end together forming a right angle, the fore end including a sharp outer end, the method comprising:

providing a safety enclosure including;

a needle housing including a finger pad with a flat surface generally perpendicular to a longitudinal axis of the needle fore end and generally parallel to a longitudinal axis of the needle aft end in both an installation position and a safety position, the finger pad operational in the installation position; and

a panel unit including a series of planar panels assembled in an enclosing, arrangement defining an enclosed area, the panel unit movable between the installation position where the needle sharp outer end projects from the panel unit and a safety enclosure safety position where the needle sharp outer end is covered by the panels;

orienting the safety enclosure in a desired location for insertion of the needle; and

applying pressure to the finger pad sufficient to cause penetration of the needle at the desired location and to move the panel unit to the installation position.

2. The method according to claim 1, wherein the needle housing further comprises an outwardly flared collar that engages a notch in the panel unit in the installation position to releasably lock the panel unit.

3. The method according to claim 1, further comprising a gripping handle to assist in the orienting step, wherein the gripping handle rests on the skin of the patient in the installation position and prevents longitudinal rocking movement of the needle.

4. The method according to claim 1, wherein the panel unit comprises side edges including elongated protuberances, the method further comprising transitioning the safety enclosure from the installation position to the safety position by pressing the elongated protuberances toward one another.

5. The method according to claim 4, wherein the panel unit comprises a first panel including a first locking means, and a second panel including a second locking means, wherein the transitioning comprises conducting the first locking means through an opening in the second panel and conducting the second locking means through an opening in the first panel.

6. The method according to claim 1, further comprising arranging adhesive tape over at least a portion of the panel unit at the desired location following, the applying step.

7. The method according to claim 6, further comprising removing the tape prior to transitioning the safety enclosure from the installation position to the safety position.
