Plural injecting device

A plural hypodermic needle and plural spring actuated injecting device comprising

• outer housing means adapted to be exteriorly manually engaged by a user,
• actuating means carried by said outer housing means for movement into an actuating position in response to a manual movement by a user with said outer housing means exteriorly manually engaged as aforesaid,
• a first cylindrical liquid container within said outer housing means,
• a first hypodermic needle disposed within said outer housing means in a storage position in operative association with said first container,
• first plunger means within said outer housing means extending into said first container,
• first spring means operatively associated with said first plunger means within said outer housing means,
• first releasable means normally retaining said first spring means in a stressed condition within said outer housing means for actuation in response to the movement of said actuating means into said actuating position to effect release of the stressed condition of said first spring means so that the spring force resulting from said release acts upon said first plunger means to move (1) said first hypodermic needle from said storage position to an extended position into the user and (2) liquid within said first container outwardly through said first hypodermic needle into the user;
• a second cylindrical liquid container,
• a second hypodermic needle operatively associated with said second liquid container,
• second plunger means operatively associated with said second liquid container,
• second spring means operatively associated with said second plunger means,
• second releasable means normally retaining said second spring means in a stressed condition operable upon actuation to effect release of the stressed condition of said second spring means,
• safety means operable (1) when in a safety position with respect to both said first and second releasable means to prevent actuation thereof as aforesaid and (2) when removed from said safety position in relation to said first releasable means to permit the actuation of said first releasable means as aforesaid and from said safety position in relation to said second releasable means to permit actuation thereof, and
• mechanical motion transmitting means operable to transmit a movement occurring as a result of the actuation of said first releasable means to said second releasable means to insure that the spring force resulting from the release of said second spring means by said second releasable means acts upon said second plunger means to move (1) said second hypodermic needle longitudinally outwardly into an extended position into the user in generally side-by-side relation to said first hypodermic needle and (2) liquid within said second container outwardly through said second hypodermic needle into said user.

• spring biased actuating means for actuating said second releasable means and
• means operable as a result of the actuation of said first releasable means for operating said spring biased actuating means to actuate said second releasable means so that the spring force resulting from the release of said second spring means by said second releasable means acts upon said second plunger means to move (1) said second hypodermic needle longitudinally outwardly into an extended position into the user in generally side-by-side relation to said first hypodermic needle and (2) liquid within said second container outwardly through said second hypodermic needle into said user.
