Abstract

A cassette containing cartridges for sampling blood from a patient. The cassette includes a container for storing a plurality of cartridges and at least one cartridge in the container. The cartridge includes a cartridge case and a lancet. The lancet has a tip and is housed in the cartridge case. The lancet can be driven to extend the tip outside the cartridge case for lancing the skin of the patient to yield blood. The container has a compartment that contains at least one cartridge. A cartridge from the compartment can be loaded onto a glucometer that drives the lancet in the cartridge to lance the skin of a patient.

Claims

1. An apparatus for sampling blood from a patient, comprising:

a support member;

a plurality of penetrating members housed in a radial pattern on said support member, each of said penetrating members having a tip, wherein the penetrating member can be driven to extend outwardly to penetrate tissue of a patient to yield blood for collection for analysis;

at least one test region receiving said blood for analysis; and

wherein each of said penetrating members and said at least one test region is housed in a cylindrical case, said case being coupled to the support member and configured to be coupled to a penetrating member driver.

2. An apparatus for sampling blood from a patient, comprising:

a support member;

a plurality of penetrating members housed in a radial pattern on said support member, each of said penetrating members having a tip, wherein the penetrating member can be driven to extend outwardly to penetrate tissue of a patient to yield blood for collection for analysis;

at least one test region receiving said blood for analysis; and

wherein the support member includes a plurality of slots for holding a plurality of cases, each case containing at least one penetrating member and one test region.

3. An apparatus for sampling blood from a patient, comprising:

a support member;

a plurality of penetrating members housed in a radial pattern on said support member, each of said penetrating members having a tip, wherein the penetrating member can be driven to extend outwardly to penetrate tissue of a patient to yield blood for collection for analysis;

at least one test region receiving said blood for analysis; and

a calibration cartridge having a function of calibration or identification of the analytical characteristics of the test region.
