A specimen transfer device adapted to receive a blood sample is disclosed. The specimen transfer device includes a housing and an actuation member. A deformable material is disposed within the housing and is deformable from an initial position in which the material is adapted to hold the sample to a deformed position in which at least a portion of the sample is released from the material. A viscoelastic member is disposed within the housing between the material and the housing and between the material and the actuation member. The viscoelastic member is engaged with the actuation member and the material such that movement of the actuation member from a first position to a second position deforms the material from the initial position to the deformed position.

The present invention provides a detection device for body fluid separation, which comprises the plurality of bottles, the upper knob member having an upper outer casing and an upper inner casing sleeved within the upper outer casing, and the lower knob member having a lower outer casing and a lower inner casing sleeved within the lower outer casing. When the upper outer casing is tightly coupled to the upper inner casing or the lower outer casing is tightly coupled to the lower inner casing, the bottles do not communicate with each other. When the upper outer casing is separated from the upper inner casing or the lower outer casing is separated from the lower inner casing, the bottles communicate with each other. Accordingly, the detection result can be quickly determined by the detection device and detection method for body fluid separation.

A container assembly is disclosed including an outer container, a hollow inner member, and a closure. The outer container has a closed bottom, an open top, and a sidewall extending therebetween. The hollow inner member is disposed within the outer container and has an inner surface defining at least one capillary channel. The inner member includes a first end adjacent to the open top of the outer container and has an outer periphery seated against the sidewall of the outer container. The closure has a proximal end and a distal end. The closure proximal end is seated at least partially within the first end of the inner member to seal the outer container and inner member and define a fluid collection chamber. The closure distal end defines a recessed area shaped to direct fluid under capillary action to the at least one capillary channel in the inner member.

A multi-functional specimen collector comprises a barrel, a shaft body disposed in the barrel, a piston disposed in the barrel and connected to the shaft body, a first seal cap connected to an end of the barrel, and a second seal cap for connecting to the piston after the shaft body is removed. An interior at the end of the barrel is disposed a stopper for restricting a moving range of the piston inside the barrel to prevent the piston from being pulled out of the barrel. The outer diameter of the stopper and the inner diameter of the barrel are designed to closely fit each other. The inner diameter of the stopper might be smaller than the outer diameter of the piston, and the inner diameter of the stopper might be larger than the largest outer diameter of the shaft body.

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.

Bodily fluid sample collection systems, devices, and method are provided. The sample is collected at a first location and subjected to a first sample processing step. The sample may be shipped to a second location and subjected to a second sample processing step that does not introduce contaminants into a plasma portion of the sample formed from the first processing step. The sample may also be mixed with other material(s) in the collection device.

A hand-held applicator (10) for collecting, mixing, diluting and discharging a sample liquid, comprising a main body (20) having an inlet-aperture (24), an outlet-aperture (26) and a chamber (22) for storing a liquid solution, wherein the chamber is connected to the inlet-aperture and the outlet-aperture, a lid (12) for covering the inlet-aperture and a tube (40), moveably supported in the inlet-aperture when the lid is covering the upper portion of the main body, wherein the tube (40) is moveable between a predetermined position outside the chamber and a position, in which the tube is at least partly located in the chamber.

An independent blood filter device depends on flow geometry to deliver blood serum or plasma free of detrimental levels of hemoglobin. It depends critically on an upstream flow rate or pressure differential limiting control element or device that limits the rate of change of pressure differential across the filter element. Pre-evacuated versions can be used to simultaneously draw blood from a living being and provide pressure differential across the filter element between an evacuated collector and a supply end open to atmosphere. A unit pressurized by hand motion employs the external shape of a partially filled blood collection tube as a piston to produce pressure in advance of the control element or device to create the pressure differential across the filter element to a collector vented to atmosphere. The control element or device is disclosed in numerous forms, including specially sized flow constrictions and compliant arrangements.

A blood sampling device is provided having holder with a manipulating end and an absorbent probe on the opposing end. The probe is of hydrophilic polymer sized to directly absorb a predetermined volume of up to about 30 microliters of blood. Ribs on the holder position the probe within a compartment of a container to prevent contact with the container. The ribs also position the probe within extraction wells.

A catheter insertion device includes a housing, a needle, a catheter, and a guide wire. The needle has a proximal end positioned in the housing and a distal end extending beyond a distal end of the housing in a first position. The catheter is positioned coaxially over the needle, and may include a flexible tube and a catheter hub on a proximal end of the flexible tube. A proximal portion of the flexible tube and the catheter hub may be positioned in the housing. The guidewire may have a proximal end positioned in the housing and a distal end positioned in a lumen of the needle. The catheter insertion device also may include a handle coupled to the catheter, wherein movement of the handle relative to the housing moves the catheter hub from a position in the housing to a position outside of the housing.
