Needle device and method thereof
First Claim
Patent Images
1. A needle device comprising:
- a housing having a base for placement against a surface of a needle penetrating site, the base including a first opening;
a needle mounted for a movement between a retracted position in the housing and an extended position, a portion of the needle extending through the first opening in the extended position;
an actuator movably mounted to the housing and movable between an unactuated position in which the needle is in the retracted position and an actuated position in which the needle is in the extended position; and
a retraction mechanism that moves the needle to the retracted position upon releasing the base from the site surface.

Abstract
A needle device has a needle retraction mechanism that retracts the needle upon removing the device from the skin surface (either intentionally or unintentionally). Once the needle is retracted, the device is rendered inoperative. The needle can be further made inoperative by bending it when one attempts to reuse the device. In another embodiment, a needle opening formed in the base of the housing can be covered to render the needle inoperative when one attempts to reuse the device. In another embodiment, the needle device instead has a needle shield that automatically covers the needle after use.

28. A needle device comprising:
-
a housing having a base adapted to be placed next to a surface of a needle-penetrating site, the base including an opening;
a needle mounted for a movement between a retracted position in the housing and an extended position, where a portion of the needle extends through the opening when in the extended position;
an actuator movably mounted to the housing and movable between an unactuated position at which the needle is in the retracted position and an actuated position at which the needle is in the extended position, the actuator being biased toward the unactuated position;
a retraction mechanism that automatically moves the needle from the extended position to the retracted position.

39. A needle device comprising:
-
a housing having a base with an opening, the base with an opening being adapted to engage a surface of a needle penetrating site;
a needle mounted for a movement between a retracted position in the housing and an extended position, where a portion of the needle extends through the opening;
an actuator movably mounted to the housing for moving the needle to the extended position;
a needle shield movably mounted relative to the housing between a retracted position and an extended position, wherein the needle shield is configured to automatically move to the extended position upon removing the base from the site surface.

45. A method of retracting a needle of a needle device comprising:
-
attaching a housing having a base to a surface of a needle-penetrating site, the base including an opening;
providing a needle mounted for a movement between a retracted position in the housing and an extended position, where a portion of the needle extends through the opening;
pushing the needle to the extended position and into the surface of the site;
releasing the needle into the retracted position by detaching the base from the surface of the needle-penetrating site.

-
48. A method of retracting a needle of a needle device comprising:
-
positioning a housing having a base to a surface of a needle-penetrating site, the base including an opening;
providing a needle mounted for a movement between a retracted position in the housing and an extended position, where a portion of the needle extends through the opening; and
automatically covering the opening after the needle is moved from the extended position to the retracted position.

-
49. A method of retracting a needle of a needle device comprising:
-
positioning a housing having a base to a surface of a needle-penetrating site, the base including an opening;
providing a needle mounted for a movement between a retracted position in the housing and an extended position, where a portion of the needle extends through the opening; and
bending the needle to misalign the needle from the opening when the needle is moved to the extended position after the needle is moved from the extended position back to the retracted position.
-
-
50. A method of rendering a needle device inoperative, comprising:
-
positioning a housing having a base to a surface of a needle-penetrating site, the base including an opening;
providing a needle mounted for a movement between a retracted position in the housing and an extended position, where a portion of the needle extends through the opening;
providing an actuator movably mounted to the housing for moving the needle to the extended position;
providing a needle shield movable between a retracted position and an extended position; and
moving the needle shield to the extended position upon removing the base from the site surface. - View Dependent Claims (51, 52, 53)
