Blood Banking and Transfusion

Business outline

Since introducing Japan's first plastic blood collection and transfusion sets in 1954, Kawasumi has been expanding its business activities globally in the blood banking and transfusion industry mainly with blood bags.

Blood transfusion related products are essential in medical care, and the demand is expected to grow due as society continues to age, global population increases and the economy of developing countries continue to grow. In addition, there is growing needs for safety enhancement in blood related products, such as the prevention of adverse effects on blood transfusion.

Kawasumi will continue to support the demand of safe blood based on the technology and quality built through the development and production of blood-related medical devices.


KARMI Blood Bag
~ Single and Multiple Blood Collection System
  • Ultra smooth siliconized needle minimizes patient's pain and discomfort during venipuncture
  • Inner surface of the bag is specially designed to minimize trauma to red cell and platelet cellular components
  • Rounded corners allow for smoother transfer of blood during the separation and transfusion processes, and results in a smaller volume of blood remaining in the bag
  • Anti-needle stick protector covers donor needle upon removal from the vein to prevent accidental needle stick injuries
  • Pre-attached vacuum tube holder facilitates secure blood sampling collection
  • Sampling pouch to collect the first portion of blood from donor and prevents contamination from indigenous bacterial on the skin
~ In-Line Leukoreduction System

Significant effects of universal leukoreduction

  • Prevention of leukocyte alloantibody production  (NHFTR, PLT TR refractoriness)
  • Prevention of transfusion transmitted infections  (CMV, HTLV, Yersinia E, vCJD)
  • Reduction of transfusion associated immunological reactions  (PTP, TAGVHD)
For Whole Blood
Filtration time <30min. (RT filtration within 24 hours after blood collection)
Residual Leukocytes* <1×106 ⁄ unit
RBC Recovery >90%
Hemolysis* <0.8% (at the end of storage)
Leukoreduced RBC Hemoglobin >43g ⁄ unit
Residual blood in the filter <35mL

In-house evaluation,2014
*Complies with EU guidelines

For Red Cell
Filtration time <45min. (RT filtration within 24 hours after blood collection)
Residual Leukocytes* <1×106 ⁄ unit
Hemolysis* <0.8% (at the end of storage)
Leukoreduced RBC Hemoglobin* min.40g ⁄ unit
Residual blood in the filter <30mL

In-house evaluation,2016
*Complies with EU guidelines

~Platelet Storage Bag
  • Made from Polyolefin to store platelets with high oxygen permeability
  • Collection, preservation, transportation and transfusion of platelets
  • Superior high oxygen permeability insures adequate oxygen for platelets
  • Safer due to no plasticizing and stabilizing agents
  • Superior in heat and cold resistance

Potassium Adsorption Filter
~Reducing Risk of Hyperkalemia and Making Safer Blood
  • Adsorption and removal of excessive potassium from packed red blood cells with SAG-M preservative solution (RBC-SAGM) that have been irradiated and/or stored for a long period of time
  • Intended patients: fetuses, premature infants, neonates, infants who are receiving exchange transfusions or extracorporeal circulation treatments or patients who urgently need rapid and massive blood transfusion to safe their life
  • Effects an exchange of excessive potassium ions (K+) with sodium ions (Na+) in RBC-SAGM
  • When dealing with human RBC-SAGM containing potassium concentration of 30 to 50mEq/L, at least 80% of the potassium is removed
      The small volume: flow rate of less than 30mL/min.
      The large volume: flow rate of less than 50mL/min.
