ABSTRACT:
A lancet and method of manufacture. The lancet comprises a wire sandwiched between an upper web and a lower web. A twist-off wire point cover is provided to protect the point of the wire, and to preserve its sterility until use. The method of manufacture includes the steps of heating the upper and lower webs, thermoforming a lower web wire groove and a lower web wire point recess into the lower web, loading a wire into the lower web wire groove such that its point is disposed within the lower web wire point recess, gluing the upper web to the lower web at a lidding station, and cutting twist-off slits into the upper and lower webs to provide the twist-off cover. Alternate embodiments of the lancet are disclosed which provide a lancet containing a valley to facilitate wire loading, and which provide finger grips on the upper and lower webs. A butterfly and method of manufacture are also disclosed.
