An apparatus includes a fluid reservoir, a sterilization member, and a transfer adapter. The sterilization member operably couples to the fluid reservoir. The sterilization member is configured to be transitioned between a first configuration, in which the sterilization member obstructs an inlet surface of the fluid reservoir and maintains the inlet surface in a substantially sterile environment, and a second configuration, in which the inlet surface is unobstructed. The transfer adapter is configured to be placed in fluid communication with a portion of a patient. The transfer adapter is configured to move relative to the sterilization member from a first position to a second position such that a surface of the transfer adapter contacts the sterilization member to transition the sterilization member to the second configuration. The fluid reservoir is placed in fluid communication with the transfer adapter when the transfer adapter is in the second position.

A blood collecting device collects blood in a short time after puncture without scattering the blood into the open air other than a container for collecting the blood. One of representative blood collecting devices has a container unit that includes a screw portion, a holder that holds the container unit serving as a system whose one end is closed, a puncture unit that can be attached to the container or the holder, a through-hole of the puncture unit, and a puncture unit protection member that protects the puncture unit and the container unit.

An object is to provide a blood test kit and a blood analysis method capable of performing a blood test with a small amount of blood at high accuracy by visualizing a volume of blood collection and keeping the volume constant. Provided is a blood test kit for analyzing a concentration of a target component in a blood sample using a normal component homeostatically present in blood, the kit including: a blood collection instrument for collecting the blood sample; a diluent solution for diluting the collected blood sample; and a storing instrument for storing the diluted blood sample, in which the blood collection instrument is a capillary.

A biological fluid separation device and a separation process that allows for efficient separation of plasma from a blood sample is disclosed. A biological fluid separation device of the present disclosure is adapted to receive a blood sample having a cellular portion or cells and a plasma portion or plasma. A biological fluid separation device of the present disclosure separates plasma from cells using a track-etched membrane and cross-flow filtration.

A kit for separating and concentrating body fluid cells is provided. The kit includes a first sealing cap provided with a first dose contact body; a first cap connection housing having a first inner connection body in which a first elastic body having a first slit line formed at an end thereof, with which the first close contact body comes into elastic contact when coupled to the first sealing cap, is inserted and disposed in an inner hole so that the first inner connection body is assembled with the first sealing cap; a first housing having one end screw-coupled to the first cap connection housing, and having an inner partition wall formed therein so that a first connection hole corresponding to the inner hole is formed through the inner partition wall; a central housing having one end screw-coupled to the other end of the first housing.

Systems, methods, and non-transitory computer-readable storage media for gathering activity data describing a user's activities from one or more activity sensors and using the activity data to predict immune-response to the activity. Predicting immune-response can involve creating, personalizing, and refining immune-response prediction models based on demographic user data, activity data, blood sample data, personal genetic information.

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.

An object of the present invention is to provide a blood analysis method in which a high level of repeatability and reproducibility is achieved with respect to measurement values in a blood sample of 50 L or less, and a blood test kit which is used for the blood analysis method. According to the present invention, a blood analysis method including a step of diluting a collected blood sample with a diluent solution; a step of determining a dilution factor by using a normal value of a normal component which is homeostatically present in the blood; and a step of analyzing a concentration of a target component in the blood sample, in which a volume of the blood sample is 50 L or less, a dilution factor of blood plasma components in the blood sample is 14 or higher, and the diluent solution is a diluent solution which does not contain the normal component which is homeostatically present in the blood, is provided.

An apparatus includes a fluid reservoir, a sterilization member, and a transfer adapter. The sterilization member operably couples to the fluid reservoir. The sterilization member is configured to be transitioned between a first configuration, in which the sterilization member obstructs an inlet surface of the fluid reservoir and maintains the inlet surface in a substantially sterile environment, and a second configuration, in which the inlet surface is unobstructed. The transfer adapter is configured to be placed in fluid communication with a portion of a patient. The transfer adapter is configured to move relative to the sterilization member from a first position to a second position such that a surface of the transfer adapter contacts the sterilization member to transition the sterilization member to the second configuration. The fluid reservoir is placed in fluid communication with the transfer adapter when the transfer adapter is in the second position.

The invention relates to a sampling assembly (1), in particular for relatively small quantities of bodily fluids. The said sample assembly (1) comprises a sample container (2) and a support assembly (15). The sample container (2) has an open end (4), an end (5) closed by a bottom (6) as well as a side wall (7). The support assembly (15) protrudes axially over the sample container (2) in the area of the closed end (5) thereof, and comprises at least two container extension pieces (16). The container extension pieces (16) are each integrally connected with the sample container (2) via a hinge assembly (17) and are pivotable from a production position aligned at an angle (18) to the longitudinal axis (8) to a use position which is aligned approximately parallel to the longitudinal axis (8).
