Fail safe point protector for needle safety flap
First Claim
1. A device for preventing reexposure of a point of a needle projecting from a housing of an apparatus wearable by a recipient for delivering a drug to the recipient comprising:
- a) a base of the housing, engaging skin of the recipient during injection;
b) a flap movably mounted to the base of the housing of the device, said flap having a protecting position in which said flap is pivoted away from the base and covers the point of the needle;
b) a secure space, andc) a guide integrated into said flap, said guide positioned relative to the point of the needle such that upon collapse of said flap from the protecting position toward the base of the housing, said guide deflects the point into said secure space thereby preventing the reexposure of the point upon said collapse.

Abstract
A method and device are disclosed for preventing a needle stick hazard in the event of a collapse of a protective needle flap of a portable drug pump. The device may include a needle guide, a secure space and/or a shield. A point of a needle is optionally deflected into a secure space upon collapse of the protective flap. The space may optionally be shielded. Optionally, the support linking the needle to the pump may pivot and/or translate. Optionally, there may be an exposing position wherein the needle protrudes through an opening in the flap. Optionally, the opening may be non-circular.

16. A device for preventing reexposure of a point of a needle projecting from a housing of an apparatus wearable by a recipient for delivering a drug to the recipient comprising:
-
a) a base of the housing, engaging skin of the recipient during injection; b) a flap movably mounted to the base of the housing of the device, said flap having; i) an exposed position in which the flap is flush to the base of the housing and at least the point of the needle protrudes through an opening in said flap; ii) a protecting position in which said flap is pivoted away from the base of the housing and covers the point and the point is not aligned with said opening; iii) a collapsed position; b) a secure space in said collapsed position, and c) a guide integrated into said flap and positioned relative to the point of the needle such that upon movement of said flap from said protecting position toward the base of the housing into said collapsed position said guide deflects the point into said secure space thereby preventing the reexposure of the point upon said movement. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method of preventing reexposure of a point of a needle projecting from an opening of a protective flap movably mounted to a housing of a portable injection apparatus upon collapse of the protective flap comprising:
-
a) covering the point of the needle after use of the apparatus by moving the protective flap from an exposed position in which the flap is flush to a base of the housing to a protecting position in which the flap is pivoted away from the base of the housing, and b) deflecting the point into a secure space upon collapse of the protective flap from the protecting position toward the base of the housing, to prevent the reexposure of the point. - View Dependent Claims (30, 31, 32, 33, 34)

35. A device for preventing a needle stick by a point of a needle projecting from a housing of an apparatus wearable by a recipient for delivering a drug to the recipient comprising:
-
a) a base of the housing, held against skin of the recipient during injection; b) a flap movably mounted to the base of the housing of the apparatus; c) a non-circular opening in said flap, the needle projecting through said non-circular opening when said flap is in an exposing position flush to the base of the housing, and d) a biasing mechanism, biasing said flap away from the base of the housing to a protecting position in which said flap covers the point and said non-circular opening is not aligned with the point.
