Problems solved by technology

[0005] There is also the disadvantage that all the tray-type compartments of the known stirrer unit move at the same speed
This is especially detrimental when accommodating blood products of different ages in blood product storage systems or blender units
Specifically, platelet concentrates typically have a lifespan of up to 4 days, the quality of which decreases with age

Embodiment Construction

[0038] figure 1 A storage system 100 for blood products according to the present invention is shown (see figure 2 ) of the stirrer unit 1. The stirrer unit 1 has a movable compartment 2 for receiving a blood product 3 . In this exemplary embodiment, a platelet concentrate in a bag is provided as blood product 3 . Compartment 2 is provided with channels 7, as shown. In addition, the stirrer unit 1 has a drive 4 for moving the compartment 2 . Furthermore, each mixer unit 1 has an upper connection side 5 and a lower connection side 6 .

[0039] Furthermore, the stirrer unit 1 has a bottom 8 provided with holes, which is arranged below the compartment 2 in the region of the lower connection side 7 . The compartment 2 is surrounded in a U-shape by an insulating body 9 , so that the access opening 10 is left open for insertion or removal of blood product 3 into the compartment 2 . The access opening 10 can be closed by a door 11 . Furthermore, the stirrer unit 1 has a side c...

Abstract

The present invention relates to an agitator unit for use with a blood product storage system, wherein the agitator unit has a movable compartment to receive blood products and a drive (4) for movement of the compartment. The invention is distinguished in that the drive (4) of the agitator unit has at least one motor (16) and a gear system (17) with at least one planetary gear unit (18), wherein the planetary gear unit (18) has at least one planet wheel (21), which is eccentrically movable by means of the motor (16), and a planet disc (19), wherein the planet wheel (21) is connected to the compartment (2) by means of a spigot (22) and rolls on an internal periphery (20) of the planet disc (19), wherein the spigot (22) is adjustable in its relative position. In addition, the invention relates to a modular blood product storage system with an agitator unit according to the invention.

Description

technical field [0001] The invention relates to a stirrer unit for a blood product storage system, wherein the stirrer unit has a movable compartment for receiving a blood product and a drive for the movement of the compartment. In particular, the invention relates to a stirrer unit for receiving a platelet concentrate placed in a bag. Furthermore, the invention relates to a blood product storage system with a stirrer unit according to the invention. The stirrer unit is also called a shaker or rocker. Background technique [0002] Specialized storage systems are usually used to store platelet concentrates, which maintain the temperature within a predetermined range and additionally have a stirrer unit that keeps the platelet concentrate in constant, mainly rotational motion. These storage systems also typically have monitoring and alarm systems to immediately indicate temperature excursions or malfunctions of the stirrer unit, allowing quick action to prevent damage to the...
