Provided are a bodily fluid-collecting device that is capable of collecting a fixed amount of bodily fluid while minimizing damage to a living body, a method for collecting a bodily fluid using the device, and a method for collecting an aqueous humor using the device A bodily fluid-collecting device 1 comprises a needle part 2 having a needle tube 3 with a needle tip 32, and a capillary 5 removably connected to a base end part 33 of the needle tube 3 in its longitudinal direction on a side opposite to the needle tip 32.

A flow restriction device may include a housing with first and second end portions forming respective first and second openings, and a cavity configured to receive an insert body defining a fluid passage that extends from a first opening of the housing at the first end portion to a second opening of the housing at the second end portion, where the fluid passage extends in more than one direction along a path between the first and second end portions of the housing to induce a resistance to a fluid flow moving through the device, thereby reducing a flow rate and pressure of the fluid, and where the fluid is blood, reduce the hemolysis index of the blood.

A system and method for measuring the percent fill of a blood sampling capillary includes a chamber for receiving a sample capillary containing a blood sample, an illuminator arranged to illuminate the sample capillary, an imaging lens aligned with the chamber and the sample capillary, an image sensor aligned with the imaging lens wherein the image sensor receives an image of the blood in the sample capillary from the imaging lens and converts the image to image data, a micro-controller circuit electrically coupled to the image sensor, and at least one of a host computer or a user interface electrically coupled to the micro-controller unit where the micro-controller circuit processes the image data into a percent fill result where the percent fill result is passed to the at least one of the host computer or the user interface.

A lancing device including a latch that pivots between a non-blocking position allowing a lancet carrier and a lancet to advance and retract through a first forward and reverse lancing stroke and a blocking position preventing further/excess/secondary oscillation of the lancet carrier and lancet. The pivotal latch can pivot about an axis perpendicular (e.g., for an L-shaped latch) or parallel/coaxial (e.g., for a sleeve latch) to the advancement and retraction motion of the lancet carrier and lancet.

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.

An arrangement for producing a sample of body fluid from an opening created in a skin surface at a sampling site including a cartridge with a plurality of compartments and a plurality of sampling sites, and a detector assembly. Each sampling site includes a skin-penetration member having a first end configured to pierce the surface of the skin and an inner lumen in communication with the first end, a spring actuator operatively associated with the skin-penetration member, and a needle hub connecting the skin-penetration member and the spring actuator. The needle hub includes a reagent pad and the spring actuator is configured to drive the skin-penetration member to form the wound opening. Each compartment at least partially encloses the skin-penetration member, the spring actuator, and the needle hub of a respective sampling site.

A fluid control device includes an inlet configured to be placed directly or indirectly in fluid communication with a bodily fluid source and an outlet configured to be placed in fluid communication with a fluid collection device. The fluid control device has a first state in which a negative pressure differential produced from an external source such as the fluid collection device is applied to the fluid control device to draw an initial volume of bodily fluid from the bodily fluid source, through the inlet, and into a sequestration portion of the fluid control device. The fluid control device has a second state in which (1) the sequestration portion sequesters the initial volume, and (2) the negative pressure differential draws a subsequent volume of bodily fluid, being substantially free of contaminants, from the bodily fluid source, through the fluid control device, and into the fluid collection device.

A blood sample collection system, may include a housing, the housing including a blood collection port; and a baffle chamber; a needle formed through the housing and into the blood collection port; and a baffle formed within the baffle chamber to counteract a vacuum within a blood collection tube when pierced by the needle.

An apparatus includes a housing, defining an inner volume, and an actuator mechanism movably disposed therein. The actuator mechanism is configured to be transitioned from a first configuration to a second configuration to define a pre-sample reservoir fluidically couplable to receive a pre-sample volume of bodily-fluid via an inlet port of the housing. The actuator mechanism is movable from a first position to a second position within the housing after the pre-sample reservoir receives the pre-sample volume such that the housing and the actuator mechanism collectively define a sample reservoir to receive a sample volume of bodily-fluid via the inlet port. The outlet port is in fluid communication with the sample reservoir and is configured to be fluidically coupled to an external fluid reservoir after the sample volume is disposed in the sample reservoir to transfer at least a portion of the sample volume into the external fluid reservoir.

A vascular access system which may be configured for blood draw may include a housing, which may include a distal end, a proximal end, and a slot disposed between the distal end and the proximal end. The slot may include a notch. The vascular access system may include a cannula hub, which may be disposed within the housing and movable with respect to the slot. The cannula hub may include a tab extending through the slot. The vascular access system may include a cannula extending distally from the cannula hub. In response to the tab being disposed within the notch, a distal tip of the cannula may be disposed within the housing. In response to advancing the tab along the slot to a distal end of the slot, the distal tip of the cannula is disposed distal to the distal end of the housing.
