Platelet Agitator

Platelet Agitator is a specialized laboratory device used in blood banks and clinical laboratories to store and maintain platelet concentrates under optimal conditions. Platelets are a vital component of blood that help in clotting and preventing excessive bleeding. However, they are highly sensitive and require specific storage conditions to remain viable. A platelet agitator ensures that platelets are constantly and gently agitated while being stored at a controlled temperature, typically around 22°C (room temperature), to prevent clumping and maintain their functionality.

Importance of Platelet Agitation

Unlike red blood cells and plasma, platelets cannot be frozen and have a very short shelf life—usually around 5 to 7 days. During this time, they must be stored with continuous agitation to maintain gas exchange and prevent platelet aggregation (clumping), which can render them useless. Without proper agitation, platelets can lose their function quickly, making them ineffective for transfusion purposes.

The constant motion provided by a platelet agitator keeps the platelets suspended in the plasma, allowing oxygen to reach each cell while facilitating the removal of carbon dioxide. This movement mimics natural blood flow and helps preserve the quality and viability of the platelets throughout their storage period.

How a Platelet Agitator Works

A platelet agitator consists of a flat or multi-shelf rack system mounted on a mechanical platform that gently moves the shelves in a horizontal, reciprocating motion. This motion ensures even and continuous mixing of the platelet concentrates stored in bags or containers. The device is often placed inside a temperature-controlled platelet incubator to maintain the correct storage temperature.

Most modern platelet agitators are designed to operate silently, reliably, and continuously 24/7. They come in various sizes and configurations to meet the storage capacity needs of different laboratories and blood banks. Some models also feature alarms and monitoring systems to alert users in case of agitation failure or temperature fluctuation.

Key Features of Platelet Agitators

1. Gentle Agitation: Designed to move at a controlled, slow speed to avoid damage to the platelets while ensuring proper mixing and gas exchange.
2. Multiple Shelves: Many models come with multi-layer shelves or trays that can hold several platelet bags at once, increasing storage capacity.
3. Quiet and Continuous Operation: Built for 24/7 operation with minimal noise, which is essential in clinical settings.
4. Durability and Low Maintenance: Made from high-quality stainless steel or corrosion-resistant materials for long-lasting use.
5. Compatibility with Incubators: Often used in combination with platelet incubators to maintain ideal temperature and agitation conditions.
6. Optional Alarms and Indicators: Some advanced models are equipped with digital displays, temperature indicators, and alarm systems for added safety and control.
