Abstract
Modular blood product storage system for temperature-regulated storage of blood products with a temperature regulation unit for temperature regulation of the blood product storage system, a base unit and at least one agitator unit with an upper connection side, a lower connection side, a movable compartment to receive the blood products and a drive for movement of the compartment, wherein the compartment is arranged between the upper connection side and the lower connection side, wherein the upper connection side of the agitator unit is selectively connectable to the temperature regulation unit or a further agitator unit, and wherein the lower connection side of the agitator unit is selectively connectable to the base unit or a further agitator unit.
Core Innovation
The invention relates to a modular blood platelet storage system for temperature-regulated storage of blood platelet concentrates. The system includes a temperature regulation unit and a base unit with a plurality of agitator units arranged between them, and an air temperature regulation system provides temperature regulated air while an air circulation device generates a circulating flow through the agitator units between the temperature regulation unit and the base unit.
Each agitator unit has an upper connection side, a lower connection side, and a movable compartment arranged between the upper and lower connection sides. The movable compartment receives the blood platelets and is movable by at least one drive to agitate blood platelets received in the movable compartment, and the lower connection side of each agitator unit is selectively connectable to the base unit or to the upper connection side of another agitator unit while the upper connection side is selectively connectable to the temperature regulation unit or to the lower connection side of another agitator unit.
The circulating flow of temperature-regulated air includes a first portion flowing from the temperature regulation unit to and through the base unit and a second portion flowing from the base unit to and through the temperature regulation unit. One portion flows through the movable compartment of each agitator unit, while the other portion flows through one or more separate air circulation passages so that the portion through the movable compartment is separated from the portion through the one or more separate air circulation passages, and each agitator unit bottom has openings below the movable compartment in the region of the lower connection side through which the first portion flows.
Claims Coverage
The independent claim in this portion defines 6 inventive features: the modular architecture, circulating temperature-regulated air, a movable compartment with drive, selective modular connection sides, a split air-circulation arrangement, and bottom openings for airflow.
Modular platelet storage with temperature regulation unit and base unit
A modular blood platelet storage system comprising a temperature regulation unit, a base unit, and a plurality of agitator units arranged between the temperature regulation unit and the base unit for temperature-regulated storage of blood platelet concentrates.
Circulating flow of temperature-regulated air through each agitator unit
An air temperature regulation system configured to provide temperature regulated air, and an air circulation device configured to generate a circulating flow of the temperature-regulated air through each of the plurality of agitator units between the temperature regulation unit and the base unit.
Movable compartment agitated by a drive within each agitator unit
Each agitator unit comprises an upper connection side, a lower connection side, and a movable compartment arranged between the upper connection side and the lower connection side, wherein the movable compartment is movable by the at least one drive to agitate blood platelets received in the movable compartment.
Selectively connectable upper and lower connection sides for modular stacking
The lower connection side of each agitator unit is configured to be selectively connectable to the base unit or to the upper connection side of another one of the plurality of agitator units, and the upper connection side of each agitator unit is configured to be selectively connectable to the temperature regulation unit or to the lower connection side of another one of the plurality of agitator units.
Separated split of circulating temperature-regulated air into compartment and separate air passages
The circulating flow includes a first portion flowing from the temperature regulation unit to and through the base unit and a second portion flowing from the base unit to and through the temperature regulation unit, where one portion flows through the movable compartment of each agitator unit and the other portion flows through one or more separate air circulation passages so that the portion flowing through the movable compartment is separated from the portion flowing through the one or more separate air circulation passages.
Bottom openings arranged below the movable compartment for air flow through the agitator units
Each agitator unit has a bottom provided with openings, where the bottom is arranged below the movable compartment in the region of the lower connection side, and the first portion of the temperature-regulated air flow flows through the movable compartment of each agitator unit and through the openings of each of the plurality of agitator units.
Overall, the claims cover a modular temperature-regulated platelet storage system using multiple agitator units with movable compartments driven to agitate platelets, selectively connectable connection sides for modular arrangement, and a split circulating air-flow architecture that separates a portion flowing through the movable compartments from a portion flowing through separate air circulation passages, including bottom openings that support airflow through the compartments.
