1. A cartridge comprising a plurality of bodily fluid sample acquisition and testing devices, each of said acquisition and testing devices comprising:
- a lancet adapted to be engaged by a lancing device;
a bodily fluid chemistry sensing strip comprising a sensing area; and
a primary support member adapted to fixedly engage said sensing strip, and to slidably engage said lance, said primary support member adapted to allow said lance to slide between an unexposed position and an exposed position.

Abstract
A lancing device integrated with a sensing strip and method of making and using the same are provided. A lance and analyte sensing strip are combined in a single, preferably disposable, device. In a preferred embodiment, a slot is provided in a support member so the lance can be engaged by a lance driver and driven into the skin producing a bodily fluid sample from a wound. The sensing area of the sensing strip is adjacent to the wound location reducing dexterity requirements for patients.

13. A method of manufacturing a bodily fluid sample acquisition and testing device, comprising the steps of:
-
inserting a lance into a primary support member having a slot for accessing said lance, sterilizing said primary support member and lance; and
after sterilizing said primary support member and lance, inserting a bodily fluid chemistry sensing strip comprising a sensing area into said primary support member such that said sensing area is adjacent to said lance. - View Dependent Claims (14, 15, 16)

17. A cartridge comprising a plurality of bodily fluid sample acquisition and testing devices, each of said devices comprising:
-
a primary support member having a bodily fluid chemistry sensing strip attached thereto, said sensing strip comprising a sensing area in proximity to a sensing end of said primary support member;
a cantilever member comprising a first end hinged to said support member;
a lancing member comprising a lancet support member and a lancet having a pointed end attached to said lancet support member, said lancet support member being hinged to a second end of said cantilever member;
said primary support member, cantilever member, and lancing member adapted to adopt a first orientation being substantially coplanar, and to adopt a second orientation with said lancing member defining an angle with said primary support member such that said pointed end of said lance is adjacent to said sensing area of said sensing strip. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. A cartridge comprising a plurality of bodily fluid sample acquisition and testing devices, each of said devices comprising:
-
a primary support member enclosing a lancet and a bodily fluid chemistry sensing strip, said primary support member having a first port adapted to allow a point of said lancet to extend out of said primary support member and a second port adjacent to said first port in fluid communication with a sensing end of said sensing strip; and
a primary support member holding mechanism adapted to drive said lancet point out of said first port, retract said lancet, and move said primary support member to align said second port with a wound created by said lancet. - View Dependent Claims (27, 28, 29, 30, 31, 32)
