A sealing cap seals a sample tube for receiving a liquid, in particular blood. The sealing cap includes a cavity delimited by a membrane and a base having an opening that can be sealed by a non-return valve. In order to reduce the volume of liquid which, during centrifugation of the sample tube sealed by the sealing cap, flows out of the sealing cap through the then open opening into the sample tube, the cavity of the sealing cap has a separating wall that divides the cavity into a first and a second sub-area. Only the second sub-area is above the opening, also meaning that only the volume of liquid in the second sub-area can flow into the sample tube.

A medical needle holder (10) having a generally hollow body (18) which extends in the direction of an axis (62) from a first end (20) to a second end (22). The first end is shaped for reception of a needle (50) therein and the second end is open to allow for insertion of a fluid receptacle (16). The first axis is substantially aligned in use with a needle positioned in the first end of the body. The needle holder comprises a grip portion (28) which extends outwardly from the body in a direction which is angularly offset from the first axis. The grip portion may be actuable between an in-use condition and a disposal condition in which the grip portion covers a needle in the needle holder. The body (18) may comprise control formations on its inner surface to allow for control over the insertion of a fluid receptacle (16) into the body.

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.

A kit and a method are disclosed for collecting and preparing a biological sample for testing where the sample is to be mixed with a buffer prior to being tested.

A device for the uninterrupted administration of fluid to an animal body during a draw of bodily fluid, e.g., blood, is disclosed. A first fluid channel is configured to selectively transport IV fluid to an animal body and to draw a bodily fluid from the body. A sealing member for sealing a bodily fluid draw port defines a concave surface on a first end. The sealing member concave surface forms an interior surface portion of the first fluid channel. A connection member is configured to connect to a catheter to the first fluid channel and defines a concave distal end. A second fluid channel continuously provides IV fluid to a lumen coaxially located within the catheter. The concave surface and the concave distal end are shaped to create fluid flow patterns that quickly and completely remove residual bodily fluid remaining after a draw of bodily fluid is completed.

A blood sample collector can be used to collect a blood sample from a subject. The blood sample collector can be placed in a receptacle of a spectrometer to measure spectral data from the blood sample while the blood sample separates. The container may comprise a window to allow light such as infrared light to pass through the container, with the blood sample at least partially separating within the container between spectral measurements, which can provide improved accuracy of the measurements and additional information regarding the sample. Measurements of the level of a biomarker surrogate in a person's blood may be used to assist the person to make beneficial changes to their diet, exercise regimen, or other aspects of their lifestyle.

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.

An instrument advancement device includes a housing comprising a fluid path, a distal end, and a proximal end, an instrument disposed within the housing, an advancement element, where in response to movement of the advancement element with respect to the housing, the instrument is configured to advance distal to the distal end of the housing, a small sample dispense device connected to the proximal end of the housing, and a blood collection device connected to a proximal end of the small sample dispense device. The blood collection device is configured to receive an evacuated blood collection container, where the small sample dispense device is detachable from the housing and configured to dispense a blood sample.

A biological fluid collection device that receives a sample and provides flow-through blood stabilization technology and a precise sample dispensing function for point-of-care and near patient testing applications is disclosed. A biological fluid collection device of the present disclosure is able to effectuate distributed mixing of a sample stabilizer within a blood sample and dispense the stabilized sample in a controlled manner. In this manner, a biological fluid collection device of the present disclosure enables blood micro-sample management, e.g., passive mixing with a sample stabilizer and controlled dispensing, for point-of-care and near patient testing applications.

A closure adapted for insertion in a tube having a first end and an opposed second end and a bore extending therethrough. The tube adapted to draw a liquid into the tube by virtue of capillary action. The closure at least partially insertable in the first end and adapted to be slidably movable between a first position and a third position. The closure includes a substantially cylindrical body having an outer surface and a proximal end adapted to be inserted inside the bore and a distal end in close proximity with the first end. The body having a plurality of channels extending along the outer surface between the proximal end and the distal end, and a seal region extending along a periphery of the outer surface between the distal end and the plurality of channels.
