The application and characteristics of plasma bags

Plasma bags are mainly used for collecting, storing and transfusing plasma in the medical field. Their applications and characteristics are as follows:

I. Application

1. Plasma collection: Plasma bags are used to collect plasma at single plasma collection stations or medical institutions. During the collection process, the plasma bag is connected to equipment such as a blood collection needle, and blood is drained into the bag by puncturing a blood vessel.

2. Plasma storage: The collected plasma bags are usually frozen to maintain the stability and effectiveness of the plasma components. The plasma bag has good sealing properties to prevent external contamination and deterioration.

3. Plasma transfusion: When plasma transfusion is required, the plasma bag delivers plasma to the patient through a blood transfusion tube or blood transfusion channel for treatment or nutritional supplementation.

II. Features

1. Avoid cross infection: The disposable design ensures that each plasma bag is used only once, effectively reducing the risk of cross infection between patients and reducing the spread of infectious diseases.

2. Hygiene and safety: The materials and design meet hygiene standards to ensure the safety and hygiene of the transfusion process.

3. Convenient and easy to use: plasma bags simplify the operation process of plasma collection and infusion, reducing the complexity and time cost of operation.

4. Reduce waste: the bag body has precise capacity markings, which can accurately measure the amount of plasma as needed to avoid waste.

5. Efficient storage: plasma bags can preserve plasma components for a long time at low temperatures to ensure their effectiveness.

6. Diverse structures:
Composition: usually includes bag body, hose, connector, protective cover and other parts.
Classification: By structure: divided into two-way pipe type and conical connector type. By capacity: common specifications are 100ml, 200ml, 400ml, 600ml, 800ml, 900ml, 1000ml, etc.

7. Material safety: the bag body and pipeline are usually made of medical soft polyvinyl chloride (containing plasticizer DEHP) or medical grade polyethylene and other materials, with good biocompatibility and chemical resistance.

8. Sterile and pyrogen-free: the product has undergone strict aseptic treatment to ensure safe use.

9. Closed pipeline system: Closed pipelines are used during collection and return to prevent contamination and improve safety.

10. Efficient separation: Used in conjunction with plasma separation cups and plasma pipelines, it can efficiently separate and collect plasma components.
