A device for delivering a substance into the skin of a patient includes a housing and a plurality of microneedles for penetrating the skin. The housing includes a bottom wall with a plurality of apertures for supplying the substance to the microneedles. The housing also includes a flexible top cover member enclosing a bladder containing the substance to be delivered. The bottom wall of the housing has at least one cannula facing the bladder. Pressing on the top cover member causes the cannula to puncture the bladder and deliver the substance to the microneedles for delivery to the patient. In one embodiment, the cannula is surrounded by a flexible member to prevent piercing of the bladder until sufficient pressure is applied to the cover member to depress the flexible member.

Lancet

A lancet assembly includes an injection molded housing with a metal stylet mounted therein and a cap or shield. The stylet is held in position by adhesive and a plurality of supports that retain a centrally located hub within a lower portion of the housing. An improved cap is provided for mounting over the stylet on the lower portion of the housing to shield the stylet prior to use. The cap also includes an octagonal flange at its lower end to ease removal of the cap from the housing and to provide a flat octagonal surface for independent standing during reshielding. The housing of the lancet assembly includes a plurality of molded-in longitudinal splines that provide a textured surface on the exterior of the housing to make the housing easier to handle and manipulate when loading the lancet assembly into a blood sampling instrument and includes an annular flange extending from the exterior surface of the housing to make insertion/removal of shielded lancet assembly into/from a blood sampling instrument easier.
