Embodiment Construction

[0031] Embodiments in accordance with the present invention may be used to transfer a predetermined volume of blood sample from a closed blood collection container to a closed blood transfer container. In particular embodiments, a user or robotic arm can transfer plasma or serum from a blood collection container without removing the upper portion of the blood collection container, and without the user actively drawing the plasma or serum into a test tube or storage tube. A blood transfer device according to various embodiments may draw a predetermined amount of blood sample into a blood transfer container without requiring a user or other circuitry to measure a specific amount of plasma or serum. Although not necessarily limited, various aspects of the invention can be understood through a discussion of examples in this regard.

[0032] Accordingly, in the following description, various specific details are set forth in order to illustrate specific examples presented herein. ...

Abstract

Embodiments in accordance with the present disclosure are directed to blood transfer apparatuses, sleeve-puncturing assemblies, and methods thereof. An example blood transfer apparatus includes a sleeve-puncturing assembly comprising a sleeve and a hollow conduit. The sleeve is configured and arranged with longitudinal portions to be placed over or engage a blood collection container. The sleeve has an open end that engages with a portion of the blood collection container and another end that provides containment of the blood collection container while the open end is engaged with the portionof the blood collection container. The sleeve further includes a lateral portion to provide support the hollow conduit. The hollow conduit and the longitudinal portions of the sleeve engage with the blood collection container and a blood collection container to provide sufficient pressure while engaged to pull a predetermined amount of plasma or serum from the blood collection container.

Description

technical field [0001] Various embodiments in accordance with the present invention relate to blood transfer devices, sleeve piercing assemblies, and methods for transferring a predetermined volume of a blood sample component, such as plasma or serum, from a sealed blood collection container to a sealed blood collection container. in the transport container. Background technique [0002] For disease diagnosis, physiological conditions, storage, and other purposes, it may be advantageous to collect blood from an organism and transfer it into a different container for further analysis and / or testing. Transferring blood (eg, plasma or serum) to another container may contaminate the user or the surrounding area. For example, blood in bulk or droplet form may contain infectious particles (e.g., viruses, bacteria) or genetic material (e.g., nucleic acids) and may contaminate the surrounding area, the user of the operational transfer, or others in the area. Pollution can cause al...
