Exemplary embodiments of a method, device, and apparatus for positioning an apparatus on a location of a tissue. For example, a substantially rigid film over an area of tissue to be treated can be provided. The film can include a positioning arrangement that facilitates a particular spatial engagement with the apparatus. The exemplary method can further include applying a portion of the film to a portion of a surface of the tissue and positioning the apparatus at the location by the engagement of the film to the apparatus using the feature of the film.

A biological fluid sampling device for collecting a blood sample from a separate vascular access device and for ejecting a portion of the collected sample to a point-of-care testing device for analysis is provided. The biological fluid sampling device includes a body enclosing a reservoir. The reservoir has an internal volume sufficient to contain enough blood for use in a diagnostic test. The sampling device further includes: an access lumen extending from a distal end of the body for establishing fluid communication between a separate vascular access device and the reservoir; an outflow lumen also in fluid communication with the reservoir; and a removable vented cap attached to the outflow lumen including a gas permeable vent in gaseous communication between the reservoir and ambient air. In addition, several sample and transfer devices are provided for obtaining a sample from a subject and transferring the sample to a point-of-care testing device.

A blood collection device including a flow path to flow blood by capillary action capable of collecting a large amount of blood is provided. The blood collection device includes an introduction inlet 23 for introducing the blood of the subject M, a substrate 20 connected to the introduction inlet 23 and including a flow path 25 to flow the blood by capillary action, and a cooling body 30 for cooling the flow path 25.

A test cartridge includes an adjustable lancet. The adjustable lancet is controlled by a controller. The adjustable lancet automatically detects a subject's finger, adjusts the lancet's height, pricks the finger to draw blood, moves a tube to collect the blood, moves the tube away from the finger, and empties the blood from the tube into a vial or receptacle. The adjustable lancet may include safety features to prevent the lancet to trigger when the subject's fingernail is facing the lancet, to control the amount that the lancet pierces the subject's finger, and/or to prevent the reuse of a test cartridge for multiple persons or multiple times by the same person. The adjustable lancet may include a massager wheel and/or a pressure bar to rub the subject's finger after the finger is pierced to facilitate drawing of the blood from the finger.

A portable hand-held miniature vein enhancer comprises: a housing, laser, one or more mirrors, mirror drive system, and sensor to determine a distance to the target. The laser emits a beam of light at a selective wavelength that images subcutaneous veins through differential absorption and reflection. The mirror(s) receive the beam of light and create a spot of light on the target, and when driven by the mirror drive system to oscillate, the spot is scanned to form a two-dimensionally shaped pattern of light. The scanned spot of light moves according to a range of angular positions of the mirror(s). When the distance to the target is at or below a threshold distance, the range of angular positions is set to a maximum, producing the largest scan pattern. When the distance increases beyond the threshold, the range of angular positions is reduced proportional to the increased distance.

The presently disclosed subject matter is generally directed to a device that can be used as a tourniquet cuff for effective blood draws and IV insertion. The disclosed device assists skilled medical professionals in locating a vessel and inserting an intravenous tube, catheter, and/or blood drawing needle therein. Particularly, the device includes a cuff that wraps around at least a portion of a patient limb (e.g., an arm). The cuff is secured on the patient's limb with a plurality of straps that are tightened and secured about the circumference of the cuff. When the device is configured on the limb of a patient, the patient's blood vessels immediately engorge with blood. In this way, the vessels can be clearly visualized by or felt by a medical professional. As a result, blood can easily and efficiently be drawn and/or an IV successfully inserted without multiple attempts at finding the vessel.

Devices associated with on-body analyte sensor units are disclosed. These devices include any of packaging and/or loading systems, applicators and elements of the on-body sensor units themselves. Also, various approaches to connecting electrochemical analyte sensors to and/or within associated on-body analyte sensor units are disclosed. The connector approaches variously involve the use of unique sensor and ancillary element arrangements to facilitate assembly of separate electronics assemblies and sensor elements that are kept apart until the end user brings them together.

A sample collection and testing device for analyzing blood is provided that includes a controller, a fluid flow pathway, a pump configured to move fluid through the fluid pathway, and an optical fluid measurement element configured to measure a light intensity of the fluid in the fluid flow pathway. The controller is configured to: start the pump to move a blood sample in the fluid flow pathway, receive a signal from the optical fluid measurement element indicating a detection of a leading edge of the blood in the fluid flow pathway, stop the pump to stop the moving of the blood in the pathway, receive a plurality of light intensity measurements from the optical measurement element, each light intensity measurement measured at a corresponding point of time, and provide a mapping of the light intensity measurements into an indication of a coagulation of the blood sample over a time period.

A minimal action, invasive blood constituent device can streamline the process for the self-monitoring of blood-related tests by holding and facilitating the use of some or all of the tools for obtaining and testing a blood sample. The device can include a slider, that when pumped, causes the device to spring-load a lancet and eject a testing strip. The device can include a trigger that, when pressed, activates the lancet by unloading the spring. A strip-lancet apparatus can combine the roles of two disposable products—a testing strip and a lancing needle—into an apparatus that can be configured for piercing the testing site as well as receiving the blood sample. A testing strip apparatus can facilitate the use and/or disposal of testing strips. A lancet apparatus can facilitate the use and/or disposal of lancets.
