血液浄化用活性炭

Biocompatible, pharmaceutical-class active carbon engineered to purify the outside blood and plasma – to provide reliable absorption of the toxic, overdosage, and metabolic residues in the field of hemoperfusion and plasmapheresis. Produced to the highest degree of cleanliness, particle integrity, and blood contact safety requirements for the integration of a certified medical instrument.

What Is Blood Purification Activated Carbon?

Blood Purification Activated Carbon is a specifically engineered, bio-compatible, pharmaceutical grade active carbon material that is produced according to strict medical equipment quality criteria and is usually coated with a bio-compatibility polymer (e.g., cellulose, albumin, or HEMA) that is intended to be directly exposed to the blood or plasma of an external purifying apparatus comprising a hemoperfusion column, a plasma exchange container, and an artificial hepatic support system.

In ECP, the patient’s blood or plasma is sent out of the body via an activated charcoal apparatus, in which dissolved toxins, drug-overdosage compounds, protein-bound metabolic residues, and inflammatory mediators are absorbed directly on the carbon surface prior to the recovery of the purified blood into the bloodstream of the patient. The mechanism solves the basic disadvantage of traditional blood dialysis — the effective removal of the tiny water soluble molecules, but not sufficient removal of the high-molecular-weight toxic, protein-bound compounds, and lipophile compounds that build up in the event of acute hepatic failure, serious drug poisoning, and fatal disease. Activated charcoal is used to fill this clinical void by providing adsorption based clearance which is complementary to or substitutes for dialysis in the case of life-threatening toxicity or metabolism events.

Biocompatible paint used in blood-purifying PAC is just as important as its adsorbability – avoiding direct contact with the original carbon surface, which could cause complement activation, platelet aggregation, and hemolysis. The choice of material, the homogeneity of the coating, the integrity of the particulate matter in the bloodstream, and the lack of extractable pollutants are the key technologies that differentiate the medical device class from all other active carbon applications.

Key Advantages of Blood Purification Activated Carbon

Effective Clearance of Protein-Bound and Large Molecular Toxins:Active carbon hemoperfusion can adsorb protein, lipophile, and HMLS, which can not be eliminated by traditional dialysis-delivering critical toxicity in cases of acute hepatic failure, overdosage, or metabolic emergency.
Rapid Toxin Adsorption Kinetics in Time-Critical Clinical Emergencies:The exceptionally large surface area and quick sorption dynamics of the PAC allow for quick and effective elimination of the toxin in the hemoperfusion course - providing a measurable decrease in the level of the circulating toxin in the therapeutic time frame that is clinically significant in the case of acute toxicity and organ failure.
Biocompatible Coating Technology Ensuring Hemocompatibility and Patient Safety: The polymer coated blood-purifying PAC avoids direct contact between the RBC and the original carbon - removing the complement activation, the depletion of platelets and haemolysis related to the non-exposed carbon, and making sure that the hemoperfusion equipment complies with the haemocompatibility criteria necessary for regulatory authorisation and safety in clinical use.
Broad-Spectrum Adsorption Covering Diverse Toxin Profiles in Critical Care: The ability to adsorb a broad variety of chemical compounds -- such as organophosphate, barbiturates, theophylline, parathion, and inflammatory cytokines -- allows it to be used across the diverse toxic profiles that have been seen in clinical toxicity, acute hepatic failure, and sepsis, but do not need to be specifically treated.
Medical Device Regulatory Compliance Supporting Clinical Procurement:Active Charcoal produced in accordance with ISO 10993 Bio-Compatibility Criteria, including complete extraction and leaching, particle integrity documents, and QMS certificates, offers a comprehensive set of technical documents needed for the submission of the Hemoperfusion Device Regulation and the Hospital Clinical Purchasing Qualifying Procedures.

業界が直面する課題

Hemocompatibility Requirements Eliminate Standard Activated Carbon Grades

Direct exposure to the human blood requires a bio-compatible polymer coated active carbon that prevents the activation of complement, platelet aggregation, and haemolysis – a technology which categorically excludes any commercial or standardized drug active carbon class from the use of a blood-purifying device.

Particle Integrity Under Continuous Blood Flow Conditions

The disintegration of carbon particles during hemoperfusion releases carbon fines into the blood stream of the patient, creating an embolic hazard that makes the mechanical strength and coating adherence in the dynamic blood-flow state a key patient safety criterion instead of a standard quality parameter.

Protein-Bound Toxin Clearance Beyond Dialysis Capability

Routine dialysis is not able to sufficiently eliminate protein binding compounds, lipophile agents, and HMLS toxic accumulation during ARF and HMI – which imposes substantial requirements on the ability of active carbon absorption and selectivity in the outside environment.

Specific Use Scenarios — Blood Purification Activated Carbon

Hemoperfusion for Acute Drug Overdose and Poisoning

In case of an acute poisoning incident involving a combination of barbiturates, organophosphates, theophylline, paraquat, etc., a blood vessel containing a bio-compatible coated active charcoal is attached to a patient’s circulatory system for absorption of circulating toxins from the blood. Such an extra-cellular approach allows the elimination of toxins at levels well above those achievable by the liver or renal system, thus creating a critical time window for recovering organs and supporting clinical treatment in life-threatening poisoning.

Artificial Liver Support in Acute Liver Failure

The inability of the liver to metabolise and secrete toxic substances – such as bilirubin, bile acids, aromatics, and proteins – is responsible for the development of HCC and multiple organ dysfunction in patients with acute or acute HCC. Active carbon hemoperfusion has been incorporated into an artificial hepatic support system like MARS and Prometheus as an adsorptive phase, which is responsible for cleaning out a portion of protein bound to a protein that can not be properly dealt with by albumin dialysis alone, thus gaining critical time for natural hepatic regeneration or transplant.

Sepsis and Cytokine Storm Management

In severe sepsis and septic shock, an uncontrolled inflammatory response generates elevated circulating levels of cytokines, endotoxins, and inflammatory mediators that drive organ failure progression. Activated carbon hemoperfusion apparatus is used as an ESRI to decrease the circulation load of such inflammation agents, mitigate systemic inflammation and maintain haemodynamic stability in critical cases where there is insufficient response to standard ICU treatment.

Plasmapheresis and Plasma Perfusion Purification

In plasma perfusion applications, the separation of the patient’s plasma – instead of the entire blood – is carried out via an active carbon absorption column to eliminate pathologic proteins, autoantibodies, lipoproteins, and toxins, prior to the recombining of the purified plasma with the cells’ blood constituents, and then sent back to the patient. The treatment of plasma instead of whole blood decreases the mechanical stress on blood cells and enables a higher carbon contact efficiency, making plasma perfusion the preferred external mode of treatment for some autoimmunity, familial hypercholesterolemia, and complicated toxin removal scenarios.

Chronic Renal Failure Uremic Toxin Clearance

In ESRD patients on routine haemodialysis, standard dialyses do not sufficiently clean up the entire range of urinary toxins – especially protein-bound compounds like indoxyl sulphate and p-cresyl sulphate, which build up gradually and cause cardiovascular complications. Active charcoal hemoperfusion is combined with routine haemodialysis to prolong urinary toxin clearance over and above that achieved by dialysis alone, thereby increasing the general adequacy of kidney substitution in those receiving dialysis.

Drug Overdose Management in Pediatric and High-Risk Patients

The natural ability of the body to detoxify itself is severely restricted in children and overdosage in children with impaired liver or kidney function – making ECAC a key intervention to speed up the elimination of toxins when it is not clinically acceptable. Children’s hemoperfusion facilities need a well-regulated particle size, optimal column volumes that are compatible with the low amount of the patient’s blood, and extremely strict biocompatibility certificates to guarantee the safety of the use of the product in the most vulnerable groups.

Post-Cardiac Surgery and Cardiopulmonary Bypass Detoxification

The CPB system exposes the blood to an artificial surface during and after CPB, which causes inflammation, the release of stress hormones, and the build-up of vasoactive substances that cause postoperative complications. The ACCC is incorporated into or is used together with CPB to absorb inflammation mediators, lipid peroxidases, and vasoactivators.

Toxicological Research and Clinical Trial Applications

Active Charcoal of Pharmacotherapeutic Group (PCTR) is utilized in a controlled clinical study environment to study ESRD dynamics, to assess novel hemoperfusion equipment designs, and to determine the sorption properties needed for regulatory submission. Research applications require active carbon with extremely well characterized pore structure, surface chemistry, and adsorption isotherms across a specified range of target molecules — providing the reproducible material baseline for reliable measurement and reporting of the clinical performance of hemoperfusion equipment.
