Title:
LANCET DEVICE
Document Type and Number:
Japanese Patent JPS5441586
Kind Code:
A
Abstract:
An automatic lancet device for use in pricking a patient's skin to yield a blood sample. The device comprises an arm pivoted at one end in a housing and protruding therefrom at its other end through an arcuate slot in the housing, the outer end of the arm being formed outside the housing as a carrier which will hold a replaceable mounted needle with its point projecting tangentially. The arm is spring-biassed in the angular direction corresponding to the direction in which the needle points, and can be held retracted against the spring means by a latch in the housing. When the latch is released the arm is swung forwardly by the spring means to effect a pricking operation. The spring is arranged to be slightly over-center with respect to the arm pivot when the arm is fully forward, to assist the recoil of the arm. A detachable finger rest is mounted in the housing, and includes a ring for resting on the patient's skin, so that the needle projects through the ring for pricking.
