Abstract
Abstract A lancet actuator device and mechanism for sequentially advancing and retracting a lancet blade include a housing having an opening for operating projection of the lancet blade. The actuator mechanism includes a drive spring structure insertably mounted in the housing and arranged to drive pivotal motion of the lancet blade including sequential thrusting of the blade from the housing aperture followed by immediate pivotally reverse retracting of the blade from the aperture into the housing as the spring deengerizes.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
106 words
A lancet actuator for sequentially advancing and retracting a lancet blade in a skin penetration operation, comprising: a housing containing a lancet blade structure and having an aperture for projection therethrough of a blade portion of the blade structure; spring means insertably mounted in said housing and arranged to drive pivotal motion of said blade structure and blade portion, said blade structure continuously pivoting on a pivot without translation relative thereto throughout both sequential pivotal thrusting of said blade portion from said aperture followed by immediate pivotal retracting of the blade portion from said aperture into said housing during said pivotal motion of said blade structure.
Claim 2
Dependent Claim
106 words
A lancet actuator for sequentially advancing and retracting a lancet blade in a skin penetration operation, comprising: a housing containing a lancet blade structure and having an aperture for projection therethrough of a blade portion of the blade structure; spring means insertably mounted in said housing and arranged to drive pivotal motion of said blade structure and blade portion, said blade structure continuously pivoting on a pivot without translation relative thereto throughout both sequential pivotal thrusting of said blade portion from said aperture followed by immediate pivotal retracting of the blade portion from said aperture into said housing during said pivotal motion of said blade structure.
Claim 3
Dependent Claim
16 words
A lancet actuator according to claim 1 wherein said spring means bears upon said blade structure.
Claim 4
Dependent Claim
25 words
A lancet actuator according to claim 1 further comprising trigger means for initiating propulsion by said spring means to drive said blade structure pivot motion.
Claim 5
Dependent Claim
36 words
A lancet actuator according to claim 3 wherein said trigger means comprises a manually deflectable trigger member having a retaining portion releasably blocking pivot of said blade structure until manual deflection in said skin penetration operation.
Claim 6
Dependent Claim
35 words
A lancet actuator according to claim 1 further comprising retainer means for retaining said blade portion internal to said housing following said thrusting and retracting in a single skin penetration operation of said lancet actuator.
Claim 7
Dependent Claim
44 words
A lancet actuator according to claim 1 wherein said said spring means in deenergized condition thereof bearing upon said blade carriage retains said blade portion internal to said housing following said thrusting and retracting in a single skin penetration operation of said lancet actuator.
Claim 8
Dependent Claim
107 words
A lancet actuator for sequentially advancing and retracting a lancet blade in a skin incision operation, comprising: a housing containing a lancet blade carriage and having an aperture for projection therethrough of a blade portion on the blade carriage; and a torsion spring mounted in said housing and arranged to drive pivotal motion of said blade carriage and blade portion, said blade structure continuously pivoting on a pivot without translation relative thereto throughout both sequential pivotal thrusting of said blade portion from said aperture followed by immediate pivotal retracting of the blade portion from said aperture into said housing during said pivotal motion of said blade structure.
Claim 9
Dependent Claim
107 words
A lancet actuator for sequentially advancing and retracting a lancet blade in a skin incision operation, comprising: a housing containing a lancet blade carriage and having an aperture for projection therethrough of a blade portion on the blade carriage; and a torsion spring mounted in said housing and arranged to drive pivotal motion of said blade carriage and blade portion, said blade structure continuously pivoting on a pivot without translation relative thereto throughout both sequential pivotal thrusting of said blade portion from said aperture followed by immediate pivotal retracting of the blade portion from said aperture into said housing during said pivotal motion of said blade structure.
Claim 10
Dependent Claim
24 words
A lancet actuator according to claim 7 further comprising trigger means for initiating uncoiling of said torsion spring to drive said blade pivot motion.
Claim 11
Dependent Claim
16 words
A lancet actuator according to claim 7 wherein said torsion spring bears upon said blade structure.
Claim 12
Dependent Claim
36 words
A lancet actuator according to claim 9 wherein said trigger means comprises a manually deflectable trigger member having a retaining portion releasably blocking pivot of said blade structure until manual deflection in said skin penetration operation.
Claim 13
Dependent Claim
38 words
A lancet actuator according to claim 7 wherein said torsion spring in deenergized condition thereof bearing on said blade carriage retains said blade portion internal to said housing following a single skin penetration operation of said lancet actuator.
Claim 14
Dependent Claim
73 words
A lancet actuator for skin penetration operation, comprising: a displaceable blade structure arranged for thrusting into a skin penetration position; and a blade impact impression structure including a deformable surface arranged on said actuator in a displacement path of said blade structure and having a configuration to deform and to produce an impression of impact thereagainst by said blade structure, thereby serving as an indicator on said actuator of the blade structure displacement.
Claim 15
Dependent Claim
73 words
A lancet actuator for skin penetration operation, comprising: a displaceable blade structure arranged for thrusting into a skin penetration position; and a blade impact impression structure including a deformable surface arranged on said actuator in a displacement path of said blade structure and having a configuration to deform and to produce an impression of impact thereagainst by said blade structure, thereby serving as an indicator on said actuator of the blade structure displacement.
Claim 16
Dependent Claim
30 words
A lancet actuator according to claim 12 wherein said impact comprises a generally pointed surface capable of distortion upon impact by said blade structure to define said impact impression thereof.
Claim 17
Dependent Claim
24 words
