Haemostasis and absorption
Learn how clot formation and absorption differ and what the reported product timing figures describe.
Haemostasis and coagulation
Haemostasis describes the process that limits bleeding. Coagulation is the part of that process in which clotting proteins generate fibrin to help stabilise the platelet plug. The product sheets describe these haemostats as adjuncts when other haemostatic methods are unsuitable.
Reported product timing
The Sigma Knit sheet describes a gel-like mass forming on contact with blood and providing a physical matrix for blood components. Clot formation and absorption measure separate processes.
The Sigma Knit sheet notes that absorption depends on tissue type, the quantity of material used and how much blood has saturated it.
- Clot formation is listed as 3–4 minutes.
- Complete absorption is listed as 7–14 days.
How to interpret timing figures
To compare timing across products or procedures, check the endpoint, test conditions and instructions for use. Review the application listings separately from timing.
