Safety hood for hypodermic needles
First Claim
1. A safety hood for hypodermic needles, comprising an elongated body having a U-shaped cross-section formed to surround and enclose a needle and two ends spaced from one another in a direction of elongation, one of said ends being closed;
- means for preventing undesired withdrawal of a needle from said hood, provided in said body; and
a pivot member provided on another of said ends, said pivot member being connected to said body and connectable to the needle and including a springy flip-flop element formed so that said body can be turned in a direction transverse to its direction of elongation between a first position in which said body surrounds and closes the needle and a second position in which said body is turned away from the needle and exposes the needle, said pivot member having a first solid portion and a second portion having lateral arms and a central angular arm which together form a flip-flop spring with said arms resiliently joined to said solid portion.
