Provided is a blood sampler including a needle for piercing a user's skin and a sampler body for receiving and holding a test strip in place during blood sampling and testing. When the test strip is inserted into the sampler body, the sampler body aligns one end of the test strip with the needle such that the blood sampled through the needle ends up on the test strip, while keeping the other end of the test strip exposed outside the sampler body such that a blood sample analyzer can be connected to the test strip without removing the test strip from the sampler body. The blood sampler and the test strip collectively form a cartridge, which can be inserted into a launcher for launching the blood sampling cartridge towards the user's skin to facilitate blood sampling.

Freshly obtained blood samples are deposited into a device that contains blood sample carriers, each of the carriers is designed to hold a fixed amount of blood and allow excess blood sample to flow through and be discarded. A desiccant within the blood sample carrier aids with the drying of the blood and the discarding of the excess sample blood. The device is stored/transported within a modified atmosphere package comprised of an impermeable sealable bag and an oxygen scavenger compound for removing oxygen from the bag.

In some embodiments, a wound monitoring and/or treatment system includes a dressing and/or housing configured to be placed in or over wound and/or skin of a patient, sensor configured to measure patient data, and controller configured to receive patient data measured by the sensor, selectively store at least some of the patient data in a memory, and communicate, via a transceiver, at least some of the data stored in the memory to an external computing device. The controller can be configured to, in response to determining that the dressing and/or housing is placed in or over the wound and/or skin, communicate, via the transceiver, to the external computing device a confirmation. The controller can be configured to, in response to receiving, via the transceiver, from the external computing device an authorization to collect patient data, store at least some of the patient data measured by the sensor in the memory.

The current invention concerns an integrated medical device for a self-collection test, which allows for both puncturing and collecting a blood sample.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

Disclosed are devices, kits, compositions, and methods for collecting, transporting, and detecting toxicants, pathogens, and biomarkers in a biological sample. The devices, kits, compositions and methods may be utilized to collect and transport dried blood samples from a skin prick and detect toxicants, pathogens, and biomarkers in the dried blood samples.

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.

Electrochemical test sensors and analysis methods are described that reduce or eliminate the pre-treatment or dilution of blood samples prior to HbA1c analysis. Thus, a blood sample obtained from a blood draw or phlebotomy may be introduced to the electrochemical test sensor for HbA1c analysis. The described test sensors immobilize or deactivate incompatible reagents, enzymes, and antibodies so they do not substantially interfere with each other during the analysis. The test sensors also use heat to catalyze reactions that otherwise would proceed at too slow of a rate to be practical.

A method for determining a concentration of an analyte in a fluidic sample is described. A sample is applied to a biosensor including an electrochemical cell having electrodes. A predetermined voltage waveform is applied during at least first and second time intervals. At least first and second current values are measured during the first and second time intervals, respectively. A turning point time is determined during the first time interval at which the measured first current values transition from a first to a second profile. The concentration of analyte in the sample is calculated based on determined turning point time and at least one measured current value. In another example, a physical characteristic of the sample is estimated based on measured current values. The concentration is calculated using a first or second model if the estimated physical characteristic of the sample is in a first or second range, respectively.

Example apparatus are provided to measure characteristics of a test strip. The apparatus may include an accessory for a mobile device to measure characteristics of a test strip. The accessory may include a mobile device adaptor and a test strip adaptor. The mobile device adaptor may include a first sheath and a second sheath coupled to the first sheath to secure the mobile device. The test strip adaptor may be detachably coupled to the mobile device adapter. The test strip adaptor is configured to receive different types of test strips.
