A medical contact shock freezer adapted for fast freezing a plurality of individual bags containing a medical liquid has the contact surface of its upper freezing plate arranged at an angle of at least 2° to the horizontal.

The present disclosure relates to carbon dioxide permeable containers for storing blood and methods for the improved preservation of whole blood and blood components. The improved devices and methods for the collection of blood and blood components provide for whole blood and blood components having reduced levels of carbon dioxide and the elimination of the plasticizer DEHP. The devices and methods provide for the preparation of carbon dioxide depleted blood and blood components for storage that improves the overall quality of the transfused blood and improves health outcomes inpatients and reduces risks associated with DEHP. The devices and methods also provide for maintenance of low oxygen content in blood and blood components during storage. Compositions comprising a blood product and an additive solution are also disclosed.

A cell processing system includes a processor connectable to a source container filled with a biological fluid, the processor including a separator configured to separate the biological fluid from the source container into at least two streams according to a process including at least one process parameter, and a controller coupled to the processor and an input. The controller is configured to receive the at least one process parameter, to evaluate the process using the at least one process parameter before performing the process, and to carry out one or more actions based on the evaluation, such as providing an output estimate to the operator, preventing the process from being performed according to a comparison between a calculated condition and a control, or providing an error indication to the operator according to the calculated condition and a measured in-process condition.

Methods and systems for priming a disposable fluid circuit for the processing of a biological fluid are disclosed. The methods and systems allow for variable and configurable priming of the flow path(s) leading to one or more biological fluid source containers.

Apparatus and methods for concentrating platelet-rich plasma is described herein. One variation may generally comprise a tube having a length and defining a channel within and one or more ports located at a proximal end of the tube and in fluid communication with the channel. A plunger may slidably translatable within the channel while forming a seal against an inner surface of the channel and a float may have a pre-selected density and defining a concave interface surface, wherein the float is slidably contained within the channel such that the concave interface surface is in apposition to the one or more ports.

The present invention relates to a method for separating lymphocytes and/or stem cells from whole blood in an automated blood separation system, wherein the quality of the collected lymphocytes and/or stem cells fractions is increased and the cell collection procedure is further automated by use of an optical sensor comprised in a detector device to measure turbidity and colour in the claimed method and in a cell separator, which can be used to perform the claimed method. The method of the invention is particularly useful to collect lymphocytes and/or stem cells fractions from whole blood, wherein the contamination of the collected cell fractions by platelets, red blood cells and granulocytes is reduced.

A system and method are provided for separating previously-collected whole blood into a red blood cell fraction and a plasma fraction by which the container of previously-collected whole blood is determined to be empty based on using the combination of the measured gross weight of the container and a calculated fluid flow rate from the container, based on weigh scale feedback. Upon detection of the empty container, flow from the container is stopped.

Described are embodiments that include methods and devices for separating components from multi-component fluids. Embodiments may involve use of separation vessels and movement of components into and out of separation vessels through ports. Embodiments may involve the separation of plasma from whole blood. Also described are embodiments that include methods and devices for positioning portions, e.g., loops, of disposables in medical devices. Embodiments may involve use of surfaces for automatically guiding loops to position them into a predetermined position.

A system and methodology for the preservation of red blood cells is described in which red blood cells are oxygen or oxygen and carbon dioxide depleted, treated and are stored in an anaerobic environment to optimize preparation for transfusion. More particularly, a system and method for extended storage of red blood cells from collection to transfusion that optimizes red blood cells prior to transfusion is described.
