The application fields of blood bag sealing and heat sealing machines

The application areas of blood bag sealing heat sealing machines are mainly concentrated in the medical and biological fields where sterile, airtight preservation and transportation of liquid biological agents are required. Its core principle is "safe sealing."

Core and Main Application Areas

1. Blood Collection and Supply Institutions (Blood Banks, Blood Centers)

This is the most traditional and primary application area for blood bag sealing machines, spanning the entire process from blood collection to dispensing.

After whole blood collection: Seals the blood collection catheter, separating the blood bag from the donor.

Component preparation process: After centrifugation, separates and seals different component bags such as red blood cells, plasma, and platelets.

Blood testing and sample retention: Seals an independent "sample braid" on the main blood bag tube for pre-transfusion infectious disease testing, blood typing verification, etc., avoiding repeated punctures of the main bag.

Before blood is sent to the clinic: Performs final sealing, and can seal sample segments for crossmatching according to hospital needs.

2. Hospital Transfusion Departments/Blood Banks
Hospitals are the end point of blood use, and sealing machines are key equipment here to ensure the safety of clinical blood use. After receiving and verifying: The blood bag tubing is sealed according to the hospital's procedures.

Pre-transfusion preparation: A dedicated sample segment for crossmatching is sealed for the patient; this is a crucial step in ensuring donor-recipient blood compatibility.

Blood aliquoting: When patients (especially children) require only a small amount of blood, a single bag of blood is aseptically aliquoted into several smaller bags, each sealed separately, to avoid waste and contamination.

Autologous blood reinfusion: The blood bag is sealed during autologous blood collection and reinfusion.

3. Biopharmaceutical and Bioproduct Companies: Used to produce various blood- or cell-based products.

Plasma protein product production (e.g., albumin, immunoglobulins, coagulation factors): The tubing is sealed during plasma collection, pooling, and aliquoting.

Cell therapy products (e.g., CAR-T cells, stem cell preparations): The connecting tubing is aseptically sealed in a closed system for cell culture, collection, aliquoting, and transfer.

Other biological liquids: such as culture media, reagents, buffer solutions, and other sterile liquids, including dispensing and sealing.
