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.

An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site includes at least one skin-penetration member having a first end configured to pierce the surface of the skin, and a inner lumen in communication with the first end; at least one actuator operatively associated with the at least one skin-penetration member; and at least one catalyst device configured to cause perfusion of body fluid at the sampling site; wherein the at least one actuator is configured to locate the at least one skin-penetration member so as to obstruct the wound opening while transporting body fluid through the inner lumen. Associated methods are also described.

A blood flow assist device includes a flexible sleeve, at least one blood flow stimulator incorporated into the sleeve, and an actuator assembly coupled to the blood flow stimulator. The sleeve has a first portion configured to receive at least a portion of a arm and a second portion configured to engage a portion of a hand. The first and second portions of the sleeve properly position each blood flow stimulator on the arm. The actuator assembly individually controls and selectively actuates each blood flow stimulator to apply a stimulus to the arm to control blood flow through a vein in the arm or hand having a vein access device connected thereto. The blood flow assist device may be paired with a blood processing device, with a controller of the blood processing device controlling the actuator assembly based on a pressure and/or flow rate of blood into the blood processing device.

A cannula insertion system for inserting a cannula into a blood vessel of a human or animal includes one or more sensors to provide one or more sensor signals representative for a location of the blood vessel, a processing device to determine a location of the blood vessel on the basis of the one or more sensor signals, a cannula insertion device to insert the cannula into the blood vessel, a positioning system supporting the cannula insertion device, and a control device arranged to control the positioning system to position, on the basis of the determined location of the blood vessel. The one or more sensors include a contact sensor to be placed on a target area of the skin of the human or animal to enable measurement with the contact sensor. The cannula insertion system includes a coupler liquid application device to apply contact liquid to the skin.

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.

A collection device which directs a flow of blood into a container and provides a controlled blood flow path that ensures blood flow from a collection site to a collection container is disclosed.

An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site includes: a housing, the housing comprising a first opening; a skin interface member disposed in the first opening, the skin interface member comprising an inner member having a second opening, and an outer member at least partially surrounding the inner member and attached to the first opening; and at least one skin-penetration member configured and arranged to project within the second opening. Arrangements having alternatively constructed skin interface members are also described.

The disclosed apparatus, systems and methods relate to devices, systems and methods for the collection of bodily fluids. The collector can make use of microfluidic networks connected to collection sites on the skin of a subject to gather and shuttle blood into a removable cartridge. The collected fluid is supplied to substrate for drying, storage and transport.

A device (1) for obtaining a biological sample that includes a blood collection device (10) and a vibration device (80) removably attachable to the blood collection device that provides pain relief is disclosed. The vibration device of the present disclosure provides pain relief to a patient by vibrating the blood collection device. The vibration device can be attached to the blood collection device before it is placed onto a finger to provide pain relief during the finger lancing as well as to aid blood flow from the finger into a collection container during the collection process.

A device for taking a sample of liquid by capillarity, including a channel for flow of the liquid delimited by two internal walls of the device between which a channel bottom extends, the distance separating the two internal walls decreasing in the direction of the channel bottom, the channel extending between a first collecting end, open onto outside of the device and configured to receive the liquid, and a second end, to enable the liquid to flow by capillarity along the channel bottom from the first end towards the second end. The channel includes, at the second end, a blocking structure to block the flow of liquid in the channel from the first end towards the second end.
