Title:
LANCING DEVICE WHEREIN PUNCTURE DEPTH IS ADJUSTED AT REAR
Document Type and Number:
WIPO Patent Application WO/2019/080823
Kind Code:
A2
Abstract:
A lancing device wherein the puncture depth is adjusted at the rear, said lancing device comprising a device cap, a cap base, a firing rod and a housing. The lancing device is provided with a depth adjustment outer sleeve and a depth adjustment central sleeve, the firing rod being located within the central sleeve, the outer sleeve being sleeved on the outside of the central sleeve. The outer sleeve is rotatably connected in the circumferential direction with respect to the housing, and is also positionally connected in the axial direction. A rotational positioning mechanism is arranged between the outer sleeve and the housing. The central sleeve is positionally connected in the circumferential direction with respect to the housing, and is also slidably connected in the axial direction. A rotational movement mechanism is arranged between the central sleeve and the outer sleeve. The central sleeve is provided with a passive impact surface which corresponds to an active impact surface of the firing rod, and the outer sleeve is provided with a manual adjustment ring which is exposed on the outside of a central/rear portion of the lancing device. The manual adjustment ring is rotated to drive the central sleeve to move in the axial direction, thereby altering the puncture depth of a needle tip. The present invention separates the puncture depth adjustment mechanism from the head portion of the lancing device, and transfers said mechanism to the central/rear portion of the lancing device, thereby solving the problem that mounting a lancet interferes with the puncture depth.
