ChitoClot Pad

Made of 100% medical-grade chitosan for bleeding control.


A Hemostatic Pad Designed to Control Surgical-related Bleeding

Anscare ChitoClot Pad exhibits high hemostatic activity in clinical use. The application of Anscare ChitoClot Pad in interventions such as angiography or percutaneous coronary intervention (PCI) can significantly shorten hemostasis and restraint time, thus reduce the risk of complications. Our ChitoClot Pad is distinctive from other commercial products — it allows for gelation after absorbing blood and has the ability to prevent exudation of absorbed blood.


  • Rapid hemorrhage control
  • Porous structure design enhances absorption rate
  • Excellent biocompatibility
  • Easy to apply and remove

Blood Coagulation Mechanism

Anscare ChitoClot Pad is composed of medical-grade chitosan, which provides excellent hemostatic efficacy. Cationic chitosan (chitosan; -NH3+) enhances platelet aggregation to accelerate blood coagulation. This activates coagulation molecules, thrombin, serotonin, ADP, TxA2, and induces aggregation of fibrin and blood clot.

Rapid Hemostatic Feature

Gauze swab 

Poor clotting results in blood spreading.

ChitoClot Pad

Excellent coagulation successfully keeps blood in the hemostasis pad.

Hemostasis Pad Clinical Trial

Safe, convenient, and effective hemostasis

  • The application of Anscare ChitoClot Pad in interventions such as angiography of percutaneous coronary intervention (PCI) can significantly shorten hemostasis and restraint time.
  • Reduces the risk of complications.
  • Shortens handling time by up to half.

Radial artery hemostasis

The clinical result * indicated that chitosan-based pad could provide betterhaemostatic efficacy after TRI compared with the Brand T compression device. The study * also found that chitosan-based pad could lower the incidence of RAO (both early and chronic radial artery occlusion) after TRI compared with the Brand T compression device.

Hemostasis Pad Clinical Use

Hemorrhage of radial artery – PTCA

Apply ChitoClot Pad to cover both skin and vascular access site. Position the centre point of Pad to the arterial puncture site.

Gently remove the end section of the sheath in a parallel-to-forearm direction. At the same time apply pressure with thumb on the arterial puncture site.

To maintain firm pressure, completely occlude the pedal pulse for approximately 3 minutes. 

To deliver compression continuously, place the gauze roll over ChitoClot Pad and wrap with elastic bandage.

Hemorrhage of femoral artery – PCI

Prior to sheath removal, clean the skin incision area and check the position of arterial puncture site and clean the surrounding of the catheter.

Gently remove arterial sheath in a parallel-to-leg direction. At the same time apply firm pressure with fingers to arterial puncture site.

Position the centre point of Pad to the skin incision site. Apply continuous pressure on both the arterial puncture site and the skin incision site for approximately 5-7 minutes. 

Tightly bind the site up with elastic bandages and place a sand bag to maintain pressure on it.
