Abstract

Abstract An integrated lancing device comprises a generally U-shaped spring member defining a pair of arms having free ends. A lance blade is carried in transverse position on one of the arms adjacent the free end, the one arm defining a trigger projection typically positioned substantially along the axis of the one arm. The other of the pair of arms carries a trigger member as an integral part thereof, with the trigger member extending toward the trigger projection. The arms may be flexed outwardly into a cocked position and held there by engagement of the trigger projection and trigger member. The integrated lacing device may be triggered to cause the arms to suddenly flex together, causing the lance to strike a part of a patient.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 257 words
An integrated lancing device which comprises: a generally U-shaped spring member defining a pair of arms having free ends; a lance blade carried in transverse position on one of said arms adjacent said free end, the free end of said one arm defining a trigger projection positioned substantially along the axis of said one arm; the other of said pair of arms carrying a trigger member as an integral part thereof, said trigger member extending toward said trigger projection, whereby said arms may be flexed outwardly into a cocked position and held there by engagement of the trigger projection by the trigger member, and the trigger member may be manipulated to cause the arms to suddenly flex together to cause the lance blade to strike a positioned body part of a patient, the other of said pair of arms having a free end and defining, adjacent its free end, an outer platform defining a first aperture and an inner platform defining a second aperture, said inner platform being positioned within the first aperture and being connected to said outer platform through a flexible connection member, said trigger member being carried in a position to move with the flexing of the inner platform at said connection member, said lance blade being positioned to pass through the second aperture as the arms flex together, whereby pressing with the body part of the inner platform of the lancing device in cocked position causes the trigger member to release the trigger projection and the lance blade to strike said body part.
Claim 2
Dependent Claim 257 words
An integrated lancing device which comprises: a generally U-shaped spring member defining a pair of arms having free ends; a lance blade carried in transverse position on one of said arms adjacent said free end, the free end of said one arm defining a trigger projection positioned substantially along the axis of said one arm; the other of said pair of arms carrying a trigger member as an integral part thereof, said trigger member extending toward said trigger projection, whereby said arms may be flexed outwardly into a cocked position and held there by engagement of the trigger projection by the trigger member, and the trigger member may be manipulated to cause the arms to suddenly flex together to cause the lance blade to strike a positioned body part of a patient, the other of said pair of arms having a free end and defining, adjacent its free end, an outer platform defining a first aperture and an inner platform defining a second aperture, said inner platform being positioned within the first aperture and being connected to said outer platform through a flexible connection member, said trigger member being carried in a position to move with the flexing of the inner platform at said connection member, said lance blade being positioned to pass through the second aperture as the arms flex together, whereby pressing with the body part of the inner platform of the lancing device in cocked position causes the trigger member to release the trigger projection and the lance blade to strike said body part.
Claim 3
Dependent Claim 13 words
The integrated lancing device of claim 1 which is free of side walls.
Claim 4
Dependent Claim 53 words
The integrated lancing device of claim 1 in which said trigger member consists essentially of a single, straight, upstanding post positioned transversely to the other of said pair of arms, said post carrying a laterally projecting trigger arm capable of engaging said trigger projection to hold the pair of arms in cocked position.
Claim 5
Dependent Claim 19 words
The integrated lancing device of claim 1 in which said outer and inner platforms are of generally circular shape.
Claim 6
Dependent Claim 39 words
The integrated lancing device of claim 1 in which the outer and inner platforms are connected by a single connection member on only one side of the inner platform, the remainder of the inner platform being free and unconnected.
Claim 7
Dependent Claim 43 words
The integrated lancing device of claim 5 in which the inner platform projects beyond the side of the other of said pair of arms which is opposed to the one of said pair of arms, to facilitate said pressing by a body part.
Claim 8
Dependent Claim 24 words
The integrated lancing device of claim 1 in which said one of the pair of arms carries a lifting handle adjacent its free end.
Claim 9
Dependent Claim 27 words
The integrated lancing device of claim 1 in which said one of said pair of arms is more flexible than the other of said pair of arms.
Claim 10
Dependent Claim 224 words
An integrated lancing device which comprises: a generally U-shaped spring member defining a pair of arms having free ends; a lance blade carried in transverse position on one of said pair of arms adjacent said free end, and a trigger projection positioned on said one arm, the other of said pair of arms carrying a trigger member as an integral part thereof, said trigger member extending toward said trigger projection; the other of said pair of arms also defining, adjacent its free end, an outer platform defining a first aperture and an inner platform defining a second aperture, said inner platform being positioned within the first aperture and being connected to said outer platform through a flexible connection member, said trigger member being carried in a position to move with the flexing of the inner platform at said connection member, said lance blade being positioned to pass through the second aperture as the arms flex together, whereby said arms may be flexed outwardly into a cocked position and held there by engagement of the trigger projection by the trigger member, and pressing with a body part of the inner platform of the integrated lancing device in cocked position causes the trigger member to release the trigger projection, to cause the arms to suddenly flex together to cause the lancet to strike said body part.
Claim 11
Dependent Claim 224 words
An integrated lancing device which comprises: a generally U-shaped spring member defining a pair of arms having free ends; a lance blade carried in transverse position on one of said pair of arms adjacent said free end, and a trigger projection positioned on said one arm, the other of said pair of arms carrying a trigger member as an integral part thereof, said trigger member extending toward said trigger projection; the other of said pair of arms also defining, adjacent its free end, an outer platform defining a first aperture and an inner platform defining a second aperture, said inner platform being positioned within the first aperture and being connected to said outer platform through a flexible connection member, said trigger member being carried in a position to move with the flexing of the inner platform at said connection member, said lance blade being positioned to pass through the second aperture as the arms flex together, whereby said arms may be flexed outwardly into a cocked position and held there by engagement of the trigger projection by the trigger member, and pressing with a body part of the inner platform of the integrated lancing device in cocked position causes the trigger member to release the trigger projection, to cause the arms to suddenly flex together to cause the lancet to strike said body part.
Claim 12
Dependent Claim 39 words
The integrated lancing device of claim 9 in which the outer and inner platforms are connected by a single connection member only on one side of the inner platform, the remainder of the inner platform being free and unconnected.
Claim 13
Dependent Claim 43 words
The integrated lancing device of claim 10 in which the inner platform projects beyond the side of the other of said pair of arms which is opposed to the one of said pair of arms, to facilitate said pressing by a body part.
Claim 14
Dependent Claim 27 words
The integrated lancing device of claim 11 in which the one of said pair of arms is more flexible than the other of said pair of arms.
