Abstract:
Apparatuses and methods of using them to collect blood, are provided, by first ensuring that the patient's skin is properly cleaned, to prevent contamination of the collected blood. One feature is a blood collection device configured to collect blood from a patient. Another feature is a scrub timer integrated into the device and configured to indicate to a user a scrub time period prior to beginning a blood draw process. The scrub timer can be configured to audibly and/or visually indicate to a user the start and stop times of a scrub cleaning process. In one embodiment, the scrub timer can be restarted, either manually or automatically, if the scrub cleaning process is not followed properly.
Abstract:
Apparatus comprising: a housing, the housing having an aperture configured to receive a body part of a user; a light emitting part supported by the housing; at least one proximity sensor disposed within the housing; and a controller configured to: receive signals from the at least one proximity sensor; determine from the signals whether a body part protrudes by a required amount within the aperture; control the appearance of the light emitting part according to the determination; cause the light emitting portion to produce a first appearance if it is determined that the body part of the user is not protruding by the required amount within the aperture; cause the light emitting portion to produce a second appearance if it is determined that the body part of the user is protruding by the required amount within the aperture; and cause the light emitting portion to produce a third appearance when a user initiates a new reading.
Abstract:
A lancet enclosed in a sterility sheet forms a lancet packet to maintain the sterility of the lancet and prevent the lancet from unintentionally piercing the sterility sheet prior to lancet actuation. In one form, the lancet is immobilized by hot tack welding a portion of the sterility sheet to the lancet. Alternatively, portions of the sterility sheet are hot tack welded together through an opening in the lancet to limit movement of the lancet.
Abstract:
Analyte monitors and their methods of use. The analyte monitors include multiple calibration fluids which may have different known concentrations of an analyte, such as glucose. The analyte monitors may also include sensing or washing fluids. The analyte monitors are configured to be calibrated with the multiple calibration fluids to potentially provide a more accurate determination of analyte concentrations. The analyte monitors can be adapted to be self-calibrating with the multiple calibration fluids.
Abstract:
An integrated-diagnostic instrument adapted to determine an analyte concentration of a fluid sample using a test sensor is disclosed. The instrument comprises a first portion including at least one opening formed therein. The opening is adapted to receive a test sensor. The first portion forms at least one compartment adapted to receive a lancing device and includes a user-interface mechanism. The instrument further comprises a second portion being hingedly connected to the first portion. The second portion includes a display.
Abstract:
A portable sampling or testing device for pharmacokinetics and physiology studies and a method for using the device in conducting tests on stationary or moving animals, or human test subjects, is disclosed. The device includes an apparatus for conducting a test on a freely moving subject, or a device which may be moved by a technician to be positioned over an immobile subject, such as a premature infant or unconscious human subject in an intensive care ward. The device is designed and sized to be mobile. In one embodiment, the device comprises a wheeled cart which may be moved by a human test subject operably connected to it. In another embodiment, the device comprises a wheeled carriage positioned above an animal which wears a sling connected to the device. The device may include an uninterruptible power supply. The method provides for sampling bodily fluids or acquiring physiological readings from the test subject. The method provides for removal of body fluids with or without reintroduction of the withdrawn bodily fluids back into the freely moving subject.
Abstract:
A portable or wearable cytometer (10) that can be used at remote locations, such as in the field or at home. The flow cytometer (10) of the present invention may help improve the healthcare of many weak, sick or elderly people by providing early detection of infection. By detecting the infection early, the infection may be more readily treatable. In military applications, the portable cytometer (10) of the present invention may help save lives by providing early detection of infection due to biological agents.
Abstract:
A tissue penetration device includes a penetrating member driver and a cartridge. A plurality of penetrating members are integrated with the cartridge. Each penetrating member is coupled to the penetrating member driver when advanced along a path into a tissue target. A penetrating member sensor is coupled to the plurality of penetrating members. The penetrating member sensor is configured to provide information relative to a depth of penetration of penetrating member through a skin surface.
Abstract:
A device and method to obtain a blood sample in a sealed configuration. The device includes a sampling assembly having a driver, a lancet, and a blood reservoir, and a pad having a proximal side and a distal side. The proximal side of the pad conforms to the shape of a skin area, and the distal side is attached to the sampling assembly. The pad and the sampling are configured to provide a sealed configuration around the skin area for transferring blood from the skin area to the blood reservoir.
Abstract:
Described here are meters and methods for sampling, transporting, and/or analyzing a fluid sample. The meters may include a meter housing and a cartridge. In some instances, the meter may include a tower which may engage one or more portions of a cartridge. The meter housing may include an imaging system, which may or may not be included in the tower. The cartridge may include one or more sampling arrangements, which may be configured to collect a fluid sample from a sampling site. A sampling arrangement may include a skin-penetration member, a hub, and a quantification member.
