A device (302) for sampling and / or analyzing blood or other body fluid of a subject. A housing (306) contains a plurality of lancets (308) and optionally includes test elements (324) to take up a sample of blood, an evaluation system and a display. A complete system that can be handled as a single device, for example in the form of a wristwatch, includes a multiplicity of test elements (324) and lancets (308), which can be brought successively to a working position to perform multiple measurements. A cassette or carrier (320) includes multiple lancets (308) and / or test elements (324), for insertion into the device.

Blood samples can be collected without substantial contamination from ambient air, such that the blood sample may be analyzed accurately for gaseous components such as oxygen and carbon dioxide. An embodiment of the device has integrated actuation, lancing, and sample acquisition components, which in some embodiments are miniaturized and / or disposable.

An automatic safe disposable blood sampling device includes a casing with a launching chamber formed therein. The launching chamber has a lancet needle-exiting hole at a front end thereof; a lancet needle arranged inside the launching chamber; a spring; a launching mechanism composed of the spring and a catch-launching mechanism; a press-launching mechanism provided on the casing; and a self-locking mechanism composed of barbs provided on the press-launching mechanism and self-locking hooks or notches provided on the casing which engage corresponding barbs. When pressed, the press-launching mechanism triggers the catch-launching mechanism, to disengage the lancet needle from the casing. The spring pushes the lancet needle so as to launch the lancet needle. During forward movement of the press-launching mechanism, the barbs pass across the self-locking hooks or notches. In the process of retraction, the barbs are locked with the self-locking hooks or notches and cannot return to their initial states.

A sampling device having a lancing apparatus, and optionally a detector and a meter. The lancing apparatus includes a replaceable cartridge of lancets, each lancet having an independent arming and drive mechanism enabling non-sequential and / or simultaneous firing of lancets. A lancet retainer independently associated with each lancet is movable to uncover an opening through which the lancet tip passes, and to release the lancet for activation. The lancets can be actuated in any order, and multiple lancets can be simultaneously actuated, if desired.

An automatic safe disposable blood sampling device, comprising a case defining an shoot chamber, said shoot chamber being provided with a lancet-exiting hole at a front end thereof; a lancet disposed slidably in said shoot chamber and provided with a puncturing tip at a front portion thereof, said puncturing tip being pointed to said lancet-exiting hole in an alignment manner, a spring disposed at back of said lancet in a shooting direction of said lancet; a locking and shooting structure provided on a side of said lancet and said case along a compression path of said spring, said locking and shooting structure being composed of an elastic arm button on said case and an elastic arm on said lancet, said elastic arm button being an extended structure on a side of said case, a button engaging end of said elastic arm button facing a locking hole provided on a side wall of said case, said elastic arm being another extended structure on a side of said lancet corresponding to said side wall of said case, a free end of said elastic arm being engaged with said locking hole in a locking state, and a root portion of said elastic arm being provided with a notch or a shrink neck oil which stress is easy to concentrate. Since a notch or a shrink neck is provided at the root portion of the elastic arm, the elastic arm disengages from the locking hole after the elastic arm button is pressed, at the same time, the elastic arm is broken to be self-destructed due to the stress concentration on the notch, therefore, the present invention is beyond retrieval after one-off shooting.

A blood sampling device for allowing a fluid pressure measurement and a fluid sample to be taken from a patient, having an inlet port configured to receive blood from the patient, an outlet port configured to be coupled to a monitoring channel having an infusion fluid, a sampling port configured for extraction of blood from the patient, a sampling channel configured to self-flush, after extraction, the blood with the infusion fluid, and an auxiliary channel for self-flushing the sampling channel.

This invention discloses a donor blood donation and sampling system including a donor needle adapted for drawing blood from a body, a blood collection bag coupled to a blood collection conduit which is coupled to the donor needle, a blood sampling conduit also coupled to the donor needle, and a sampling tube assembly arranged for selectable fluid engagement with the blood sampling conduit and for selectable clamping engagement with at least said blood collection conduit. A donor blood donation and sampling method is also disclosed.

A method and apparatus (2) for obtaining a sample of blood. An embodiment consists of an apparatus (2) which integrates lancing (12), sample collection, and analysis. The presence of patients finger on the active sampling area can be sensed by monitoring the pressure applied by the finger on the device (2).

A closed blood sampling system within a pressure monitoring line having a control valve that enables a clearance reservoir to be isolated from the pressure column when no samples are being taken. The valve is a stopcock-like device that includes a rotating valve member and attached control handle with clear visible and tactile indicators for the mode of operation. The rotating valve member has a number of internal and circumferential channels for connecting or disconnecting select ports in the core of the valve. By isolating the clearance reservoir, the quality of the pressure signal is improved such that the sampling line can be lengthened for greater convenience in the intensive care or operating room. The valve may also incorporate a blunt cannula sampling site therewithin.

An automated blood sampler integratable with a glucose monitor comprises a catheter connected to a tube-set forming a single blood passageway; a clamp-on air-bubble sensor and a occlusion sensor externally attached to the tube set; a single peristaltic pump and two 3-way pinch valves attached to the tube set and control fluid flow. The sampler draws blood from a stationary patient, samples the blood for analytical measurement of blood parameters; after which the passageway is rinsed, the blood re-infused, and slow saline infusion prevents vein collapse. The cycle repeats at user or predefined intervals. In another preferred embodiment, blood is not re-infused, and only one 3-way pinch valve is used.
