Abstract

A lancing device (1) for use with a lancet (7) for obtaining a blood sample is disclosed. The lancing device comprises a housing (2); a probe (10) disposed in the housing (2); and a probe actuator (15) for linearly displacing the probe (10). The probe (10) is configured for releasably engaging a lancet (7) and is provided with sliding surfaces for slidably (32, 33) engaging a pair of guides (23, 24). Each sliding surface (32, 33) has a radius of curvature centred about a curvature defining axis, the curvature defining axis being coincident with a central longitudinal axis of the lancet (7) when the lancet is engaged by the probe (10). The sliding surfaces (32, 33) are continually biased against the pair of guides (23, 24) such that when the lancet (7) is engaged by the probe (10), the lancet (7) is prevented from translating in any other direction than in a direction parallel to its central longitudinal axis during linear displacement of the probe (10).

Description

technical field [0001] The invention relates to a blood sampling device. In particular, it relates to a blood collection device utilizing a blood collection needle assembly and integrating a testing instrument. Background technique [0002] Lancing devices are typically used in the medical field to pierce or disrupt the skin surface of a finger to extract a small blood sample for self-diagnosis. This process may include inserting the test strip into the analyzer, using a lancing device to prick the tip of someone's finger to obtain a drop of blood, transferring the drop of blood to the test element of the test strip, and checking the analyzer for individual analyte concentrations in the drop readings. The analyte could be blood sugar in a diabetic patient, cholesterol in a cardiovascular patient, uric acid in a gouty patient, monitoring the effect of a treatment or the presence of illicit drugs, etc. Typically, such diagnoses are repeated many times a day, and it is desir...
