Hypodermic needle safety device with sliding outer cover
First Claim
1. A needle protection device for use with a hypodermic needle and a reservoir, the device comprising:
- an extension having front and back ends and a central cavity therethrough;
a front end connection at the front end of the extension for connecting the hypodermic needle to the extension;
a back end connection at the back end of the extension for connecting the reservoir to the extension; and
an outer cover slidably disposed about the extension and shiftable between an extended position where the hypodermic needle is covered and a retracted position where the needle is exposed; and
a means for retaining the outer cover in the extended position, which is disengageable by rotation of the outer cover with respect to the extension.

Abstract
A safety device for preventing accidental injury from hypodermic needles comprises an extension for attachment to a standard medical syringe. A standard hypodermic needle attaches to the opposite end of the extension and the extension has an inner cavity for conveying fluid between the syringe and the needle. An outer cover is disposed about the extension for sliding along the length of the extension to cover the needle. The safety device is easily modified to perform as a system for collecting blood or other fluid from a patient by adding a special needle and a blood collection holder at the back end of the extension. In this configuration, the outer cover guards the standard needle and the blood collection holder covers the special needle to prevent accidental injury or disease transmission.

9. A needle protection device for use with a hypodermic needle and a reservoir, the device comprising:
-
an extension having front and back ends, and a central cavity therethrough; a front end connection at the front end of the extension for connecting the hypodermic needle to the extension; a back end connection at the back end of the extension for connecting the extension to the reservoir; an outer cover slidably disposed about the extension and shiftable between an extended position where the hypodermic needle is covered and a retracted position where the needle is exposed; and pin and channel means comprising a pin and a channel located on the extension and the outer cover, the channel defining front and back end retaining terminals; wherein the pin locks into the back end retaining terminal to secure the outer cover in its extended position and wherein the pin locks into the front end retaining terminal to secure the outer cover in its retracted position, and wherein the pin is disengageable from the front and back end retaining terminals by rotation of the outer cover with respect to the extension. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
