Three Hemostasis Technologies
Full-Spectrum Comparison of 15+ Core Parameters
Based on clinical data and tactical feedback, an in-depth comparison of chitosan, kaolin, and zeolite technologies. Review this matrix and you will know exactly which to choose.
Three Materials at a Glance
Chitosan
Top Choice for Anticoagulated PatientsCharge adsorption mechanism, independent of coagulation system. <=30s arterial hemostasis, natural antibacterial >=99%, fully biodegradable in vivo. The gold standard for clinical surgery and complex wounds.
Kaolin
Best for Mass DeploymentActivates intrinsic Factor XII, zero exotherm, up to 5-year shelf life. 10M+ global deployments. Optimal balance of efficacy and cost. Standard equipment for pre-hospital and defense procurement.
Zeolite
Extreme Scenario SpecialistMolecular sieve ion-exchange dehydration, <=60s arterial occlusion. New-generation formula controls temp to 2-4 deg C, eliminating burn risk. Specific choice for tactical medicine and fatal hemorrhage.
Hemostasis Reaction Chain Analysis
Understand how different technologies intercept the threat of exsanguination at the molecular level.
Physical Plugging & Adsorption
Kaolin and zeolite rapidly adsorb water from blood through their unique porous structures. This process instantly increases the local concentration of clotting factors at the wound site, laying the foundation for subsequent thrombus formation.
Charge Neutralization & Adhesion
Chitosan releases a large number of positive charges that undergo intense electrostatic neutralization with negatively charged red blood cells. Without relying on the body's own coagulation mechanism, it directly forms a robust mechanical seal at the wound.
Cascade Reaction Acceleration
Kaolin's surface activates Factor XII, initiating the intrinsic coagulation pathway. All three technologies achieve effective interception of hemorrhagic shock through different scientific pathways.

Application-Based Selection Guidance
Clinical & Advanced Surgery
Your patients are on anticoagulant medications and conventional hemostasis is completely ineffective. You need a hemostatic material that does not depend on clotting factors, is biodegradable in vivo, and offers broad-spectrum antibacterial protection.
Focus on biosafety, antibacterial performance, and clinical compatibility with sensitive areas. This is the primary domain for chitosan technology.
Pre-Hospital Emergency & Disaster Response
Your EMTs have limited training time and your ambulance fleet is large. You need ready-to-use hemostatic materials with up to 5-year shelf life and zero-exothermic safety.
Pursuing the optimal balance of efficacy and cost. This is the cornerstone application for kaolin technology.
Military, Law Enforcement & Defense
Your soldiers operate from -30 deg C extreme cold to 60 deg C heat. Arterial gushing is fatal in 60 seconds. You need all-temperature stable, second-grade hemostasis, one-hand-operable tactical hemostatic materials.
Pursuing maximum reliability under extreme conditions. An integrated application of kaolin and chitosan.
Technology Selection FAQ
Why are chitosan and kaolin the most widely adopted technologies?+
Kaolin achieves the optimal balance of efficacy and cost by activating the intrinsic coagulation pathway, making it the standard equipment for defense agencies worldwide. Chitosan, with its unique charge adsorption mechanism and natural antibacterial properties, has become the gold standard for clinical, complex wound, and anticoagulated patient hemostasis. Together, these two technologies address over 90% of professional hemostasis needs.
Are chitosan hemostatic products safe for people with shellfish allergies?+
Chitosan produced by Ruten undergoes extensive purification and deacetylation, removing the protein impurities that may cause allergic reactions. Clinical studies demonstrate that high-purity chitosan has an extremely high safety profile in shellfish-allergic populations.
Why should anticoagulated (heparinized) patients choose chitosan first?+
Chitosan's hemostasis mechanism is physicochemical: positively charged chitosan directly binds to negatively charged red blood cells to form a stable 'blood clot' seal. This process does not rely on the body's own coagulation cascade, so it remains effective even in an anticoagulated state.
Has zeolite's temperature rise issue been resolved?+
Yes. Ruten's new-generation zeolite formula uses ion-exchange and pre-hydration technology to strictly control the exothermic temperature rise within 2-4 deg C, completely eliminating the tissue burn hazard of traditional zeolite products.
