Medical devices
First Claim
1. A medical device, comprising:
- a needle having a proximal end and a sharp distal tip;
a needle hub connected to proximal end of the needle;
a housing defining an open distal end, wherein the needle hub and needle are slidably disposed in the housing between a retracted position wherein said needle is contained within said housing and an extended position wherein said needle extends outwardly from the open distal end of said housing; and
a door having a substantially planar surface rotatably mounted adjacent to the open distal end of the housing, wherein said door is rotatable between an open position wherein said needle can be in said extended position and a closed position wherein said door closes said open distal end of said housing to contain said needle within said housing in said retracted position and prevent said sharp distal tip of said needle from extending past the open distal end of said housing.

Abstract
A medical device includes a hollow needle for piercing the skin of a patient. Prior to use, the needle is located in a needle protected position within a housing. The needle can be moved outwardly from the needle protected position to an extended position where it is ready for use with the patient. After use, the needle is retracted back into the housing to the needle protected position. A door is positioned at the distal end of the housing and has an aperture. The door is slidable between a first position where the needle is in alignment with the aperture in the door so that the needle can pass through the aperture to be moved to its extended position and a second position where the needle does not line up with the aperture and thus the needle cannot be moved from the needle protected position to the needle extended position.
