Abstract
A bodily fluid sampling device includes a piercing device and a sensor enclosed in a housing. A cassette, which contains test media, is positioned proximal to the sensor so that the sensor is able to analyze a bodily fluid sample collected on the test media. The cassette includes a supply portion from which unused test media is supplied and a storage portion in which contaminated test media is stored after exposure to the bodily fluid. The cassette is adapted to collect a series of bodily fluid samples without requiring disposal of the test media.
Claims28
A cassette, comprising:
- a test tape having a plurality of test sections to test a plurality of body fluid samples;
- a cover protecting the test tape prior to use;
- and
- an exposure device configured to permit access to a test section of the test tape covered by the cover.
A sampling module comprising:
- a module body portion having a sampling site adjacent a lancet exit port where the sharpened distal tip of the lancet exits a distal end of the module body portion that includes a sample cavity in a distal end surface of the module body portion;
- a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the module body portion and extendable from the lancet exit port;
- and
- a sample reservoir in fluid communication with a sample cavity of the module body portion.
A tissue penetration sampling device for collecting blood from the skin of a patient, the device comprising:
- a sampling module having a sampling site, the sampling site having a sample input port,
- a sample reservoir in fluid communication with the sample input port,
- a lancet maintained within the sampling module, the lancet having a lancet tip adjacent the sample input port, and
- a lancet driver coupled to the lancet to drive the lancet tip through the opening to lance the skin when the lancet driver is actuated,
- the device being configured to allow actuation of the lancet driver, lancing of the skin, collection of the blood, and movement of the blood to the sample reservoir seamlessly by forming a substantially airtight seal at the opening when the skin is firmly pressed against the sampling site.
A sampling module for use in collecting blood from the skin of a patient, comprising
- a body portion,
- a sampling site on the body portion defining a sample input port, the sampling site shaped to conform to the skin and to form a substantially airtight seal with the skin,
- a lancet disposed in the body portion, the lancet having a lancet tip adjacent the sample input port, wherein the lancet is operable to send the lancet tip through the opening to lance the skin of the patient, and
- a reservoir in fluid communication with the sample input port, the sampling acquisition module configured to allow seamless sampling of the blood, and integrated lancing of the skin, collection of the blood through the sample input port, and movement of the blood to the sample reservoir.
A method of collecting blood from the skin of a patient, the method comprising:
- a) contacting the skin of the patient with a blood sampling device, and
- b) performing a single initiating act resulting in the blood sampling device lancing the skin, collecting blood from the skin, and moving blood to a reservoir within the sampling device.
A sampling module cartridge comprising a plurality of sampling modules interconnected in an array and configured for sequential use.
A sampling module cartridge comprising:
- (a) a plurality of sampling modules interconnected in an array by a flexible member;
- and (b) a supply canister that is disposed about an unused portion of the sampling module belt.
A method of collecting and testing a series of blood samples, the method comprising:
- a) providing a sampling module cartridge and a reader device, the sampling module cartridge including a plurality of sampling modules, each sampling module adapted to perform a single blood sampling cycle of lancing, collection of a blood sample, and testing of the blood sample;
- b) coupling the sampling module cartridge to the reader device;
- c) initiating the blood sampling cycle and obtaining a first blood sample;
- d) testing the first blood sample obtained;
- e) advancing the sampling cartridge to bring another sampling module online;
- f) initiating another blood sampling cycle and obtaining a second blood sample;
- and g) testing the second blood sample.
A tissue penetration sampling device comprising a controllable lancet driver operatively coupled to a cartridge of sampling modules.
A sampling module cartridge comprising a plurality of sampling modules disposed within a cartridge housing and configured for serial use by a lancet driver.
