Blood bag sealing and heat sealing machine
A blood bag sealing heat sealer is a specialized medical device that uses the principle of heat sealing to heat, pressurize, fuse, and cool the tubing of a plastic blood bag, thereby achieving a permanent seal and severance.
Core Objective: To establish a sterile, leak-free, and robust seal, ensuring the safety of blood throughout the entire process of collection, separation, storage, transportation, and transfusion.
Alternative Method: Completely replaces traditional, unsafe, and unreliable methods such as knotting and metal clamping.
Core Application Scenarios (Blood Bank/Hospital Transfusion Department Workflow)
This is its standard operating procedure in the blood collection and supply system:
Whole Blood Collection Point: Immediately after blood donation, the tubing between the collection needle and the blood bag is heat-sealed.
Component Separation Center: Separates and seals individual sub-bags containing red blood cells, plasma, platelets, cryoprecipitate, etc., from the multi-bag system.
Sample Retention: Creates multiple independent "braided tubes" or "sample segments" on the main tube for blood typing, infectious disease screening, crossmatching, etc., achieving "one bag of blood, multiple tests, and sample homology." Hospital Blood Transfusion Department:
Receiving Blood: After verification, the interface is sealed.
Blood Crossmatching Preparation: A dedicated crossmatching sample segment is sealed for specific patients.
Blood Allocation: One bag of blood is aseptically aliquoted into multiple bags (e.g., for small-dose pediatric transfusions).
Final Distribution: Before the blood is sent to the ward, a final check and sealing are performed.
