Abstract: A puncture needle according to the present disclosure includes a puncture portion having a blade surface at a distal-end surface; and a retained portion connected to a proximal-end puncture-portion side and configured to be retained by a hub. The puncture portion includes a slit extending to the distal-end surface. The retained portion includes: a tubular portion having a substantially constant outer diameter larger than a maximum outer diameter of the puncture portion, and a tapered portion located between the puncture portion and the tubular portion, an outer diameter of the tapered portion gradually decreasing from a tubular-portion side to a puncture-portion side, wherein in a lateral view with the slit facing upward, lower contour lines of the puncture portion, the tubular portion, and the tapered portion are collinear.

Abstract: A cleaning tool (10) includes a cleaning head (11) and a handle (12) and is to be used with a cleaning sheet attached to the cleaning head (11). The cleaning head (11) has a gradual-liquid-release mechanism (16) including a liquid reservoir (14) and a gradual-liquid-release portion (15) that, by the action of hydrostatic pressure from above, gradually releases a liquid agent supplied to the liquid reservoir (14) to a cleaning face (17a) provided by a cleaning cushion (17) of the cleaning head (11) while causing the liquid agent to pass through a multitude of fine flow paths. The gradual-liquid-release portion (15) is provided continuously across substantially the entire width in the length direction of the substantially rectangular cleaning head (11) as viewed along the short-side direction of the cleaning head (11), the portion (15) provided facing the cleaning face (17a) of the cleaning head (11).
