A dermal patch for collecting a physiological sample includes a housing with a collection chamber, a sample channel and a pin within a receptacle of the housing. The sample channel is configured to direct a physiological sample drawn from a subject to the collection chamber. The pin is removably positioned within the receptacle and is configured to move from an undeployed position to a deployed position. The pin is configured to seal the receptacle when in the undeployed position and is further configured to facilitate generation of negative pressure in the sample channel when the pin is moved from the undeployed to the deployed position.

A blood collection apparatus may include a connector, which may include a distal end, a proximal end, and a lumen extending there between. The distal end may include a male luer lock fitting configured to couple to a proximal end of a catheter adapter, and the proximal end may include a male luer slip fitting. The blood collection apparatus may include a lid, which may include a body, a closure, and a tether connecting the body to the closure. The body may include a cover portion and an inner wall extending from the cover portion. The inner wall may be aligned with an aperture extending through the cover portion. The inner wall and the aperture may form a channel configured to receive the male luer slip fitting.

Disclosed are methods, device kits, and systems for improved quantification of mRNA from whole blood. More particularly, the devices and kites related thereto are useful for the controlled and repeatable ex vivo stimulation of whole blood.

Provided herein is a device including a housing having a proximal end, a distal end, and a sidewall therebetween defining an interior, a fluid conduit displaceably received within the housing interior and having a proximal end and a distal end, the fluid conduit having a first conduit portion at the proximal end of the fluid conduit and a second conduit portion at the distal end of the fluid conduit, wherein the fluid conduit is configured to be advanced from a first, proximal position in which the second conduit portion does not extend beyond a distal end of a catheter of the intravenous catheter assembly to a second, distal position in which the second conduit portion extends beyond a distal end of a catheter of the intravenous catheter assembly, wherein at least a portion of the fluid conduit is configured to be antithrombogenic.

Diagnostic devices and methods are provided for screening for a disease condition, including a cancer condition or a mendelian disease. The diagnostic devices allow for in vivo contact of cell-free nucleic acids or circulating tumor cells. The diagnostic device has a needle with a body and a detection reaction module attached to the body.

The present invention relates to a continuous blood glucose measurement apparatus which, by manufacturing a body-attachable unit in an assembled state inside an applicator, minimizes the additional work by a user for attaching the body-attachable unit to the body and thus enables the body-attachable unit to be attached to the body simply by means of operating the applicator, and, by providing a wireless communication chip on the body-attachable unit and enabling communication with an external terminal, can be used in a simple and convenient manner without the additional work of connecting a separate transmitter and enables easier maintenance and management, and, by having the operation of the body-attachable unit initiated by means of the user's manipulation after being attached to the body, enables the operation initiation point to be adjusted to an appropriate point as necessary by the user, enables an operation initiation in a stabilized state and thus enables more accurate blood glucose measurement.

Methods for processing a vessel, for example to provide a gas barrier or lubricity, are disclosed. First and second PECVD or other vessel processing stations or devices and a vessel holder comprising a vessel port are provided. An opening of the vessel can be seated on the vessel port. The interior surface of the seated vessel can be processed via the vessel port by the first and second processing stations or devices. Vessel barrier and lubricity coatings and coated vessels, for example syringes and medical sample collection tubes are disclosed. A vessel processing system is also disclosed.

In one embodiment, a mixing device includes a sleeve that forms an inner space configured to receive a sample container, a housing associated with the sleeve, a mixing element contained within the housing that is configured to mix liquid contained within the sample container, and an activation element configured to activate the mixing element when the activation element is triggered.

A blood sampling device (1) comprising a housing (10) and a lancet (50). The housing has a fixed abutment surface for holdingly engaging the lancet in a rearward primed position. The blood sampling device further comprises a trigger (22) moveable from a rest position to a fire position to release the lancet for forward movement, wherein the trigger deflects the lancet body in a direction generally transverse to the longitudinal axis of the housing such that the lancet body may move forwardly past the fixed abutment surface.

An apparatus includes a housing, a flow control mechanism, and an actuator. At least a portion of the flow control mechanism is movably disposed within the housing. The apparatus further includes an inlet port and an outlet port, and defines a fluid reservoir. The outlet port is fluidically coupled to a second fluid reservoir and is fluidically isolated from the first fluid reservoir. The actuator is configured to move the flow control mechanism between a first configuration, in which the inlet port is placed in fluid communication with the fluid reservoir such that the fluid reservoir receives a first flow of bodily-fluid, and a second configuration, in which the inlet port is placed in fluid communication with the outlet port.
