Platelet Pooling and Storage Bag with Filter for Leukoreduction
Product Introduction – Disposable Leukocyte-Depleted Platelet Storage Bag (1000ml)
The Disposable Leukocyte-Depleted Platelet Storage Bag (1000ml) is a specialized, sterile, single-use medical device designed for blood collection and supply institutions. It is intended for the manual collection, preparation, mixing, leukocyte depletion, and storage of mixed platelet concentrate. This advanced closed-system bag enables the simultaneous realization of platelet mixing, high-efficiency leukocyte removal, and specialized preservation in one integrated process, meeting the demanding requirements of modern transfusion medicine.
Intended Use
This product is used in conjunction with blood collection bags to manually prepare and store leukocyte-depleted mixed platelet concentrate. It is particularly suitable for blood centers and transfusion services that require high-quality, leukocyte-reduced platelet products with extended storage capability.
Product Specification
- Capacity: 1000ml
Key Features & Advantages
- Integrated Multi-Function DesignThe bag system allows simultaneous platelet mixing, leukocyte depletion, and specialized preservation within a single closed sterile environment, significantly streamlining the preparation workflow.
- High-Efficiency Leukocyte DepletionEquipped with an advanced integrated filter that effectively removes leukocytes from platelet concentrate, reducing residual white blood cells to meet stringent international standards for leukocyte-depleted platelets and minimizing transfusion-related immune complications.
- Optimized Platelet PreservationThe specially designed storage environment and material formulation help maintain platelet viability, function, and metabolic activity during storage, supporting extended shelf life while preserving hemostatic effectiveness.
- Closed-System SafetyThe fully closed configuration reduces the risk of bacterial contamination during mixing, filtration, and storage, ensuring the highest level of product sterility and safety for clinical transfusion.
- Convenient Manual OperationThe 1000ml capacity and user-friendly tubing design facilitate efficient manual collection, gentle mixing, and easy transfer of platelet concentrate, making it ideal for blood banks performing manual platelet preparation.
- Improved Transfusion SafetyBy combining leukocyte depletion with specialized preservation in one step, the product helps reduce the incidence of febrile reactions, alloimmunization, and other adverse effects associated with platelet transfusion.
This disposable leukocyte-depleted platelet storage bag provides blood collection and supply institutions with a reliable, efficient, and innovative solution for producing high-quality mixed platelet concentrate, contributing to enhanced blood safety and better patient outcomes in transfusion medicine.
FAQs
Q1: What is the primary use of this 1000ml platelet pooling and storage bag?
A: This product is designed for blood collection and supply institutions to manually collect, pool (mix), prepare, and store leukocyte-depleted mixed platelet concentrate.
Q2: What makes this product different from standard platelet storage bags?
A: It is currently the only device in China that integrates three critical functions into a single system: mixing multiple units of platelets, leukocyte depletion (filtration), and specialized preservation.
Q3: What does "leukocyte-depleted" or "leukoreduction" mean?
A: It refers to the process of filtering out white blood cells (leukocytes) from the platelet concentrate. This reduces the risk of adverse transfusion reactions, such as febrile reactions or alloimmunization, in recipients.
Q4: What is the capacity of this storage bag?
A: The product specification is 1000ml, which is suitable for pooling multiple units of platelet concentrates into a single storage container.
Q5: How does this bag help in manual preparation of platelets?
A: The bag system is designed to connect with standard blood collection bags, allowing technicians to manually pool multiple platelet units into this 1000ml bag while passing through an integrated leukoreduction filter.
Q6: Is this a closed system? Why is that important?
A: Yes, it is designed as a closed system. This maintains sterility during the pooling and filtration process, significantly reducing the risk of bacterial contamination and extending the shelf life of the platelet concentrate.
Q7: What does "special preservation" mean in the context of this product?
A: The bag is made from specialized medical-grade materials that are optimized for platelet storage. These materials allow for better gas exchange (oxygen and carbon dioxide) and maintain the pH level, which is crucial for keeping platelets viable and functional during storage.
Q8: Can this product be used for both whole blood-derived platelets and apheresis platelets?
A: It is specifically mentioned for manually collected (whole blood-derived) platelets. It is designed to pool several "buffy coat" or "platelet-rich plasma" derived units into one bag after filtration.
Q9: What are the benefits of performing leukocyte depletion during pooling?
A: Performing leukoreduction during the pooling process is efficient and ensures that the final mixed product is already pathogen-reduced (by leukocyte removal) and ready for transfusion, saving time and handling steps in the lab.
Q10: How does this product improve transfusion safety?
A: By effectively removing white blood cells and providing an optimal storage environment, it helps prevent febrile transfusion reactions, reduces the risk of HLA alloimmunization, and minimizes the transmission of leukocyte-associated viruses.
Q11: Is this product suitable for hospitals or only for large blood centers?
A: It is designed for "blood collection and supply institutions," which includes both central blood banks (blood stations) and hospital transfusion departments that perform manual platelet pooling.
Q12: What is the recommended storage temperature for platelets in this bag?
A: While not specified in the text, standard platelet storage requires controlled room temperature (+20°C to +24°C) with continuous gentle agitation. This bag is designed to maintain platelet quality under these conditions.
Q13: Does the 1000ml volume mean it can store a full dose for transfusion?
A: Yes. A therapeutic adult dose of pooled platelets is typically derived from 4-6 whole blood donations and requires a bag large enough to hold the combined volume, which this 1000ml bag accommodates.
Q14: How should this product be disposed of after use?
A: As a single-use medical device that comes into contact with blood products, it should be disposed of according to medical waste regulations after use.
