ISO13849-1, Category 3/4, Safety Dump Valves, VG342 / VP744 Series - Quickly exhaust residual air
pressure in conformance to Category 3/4 and ISO13849-1 for machine safety.
The additional indication allows surgeons in the European Union to use HEMOPATCH to address bleeding and seal suture lines in diverse, complex procedures such as sealing residual air
leaks during lung surgery, or replacing dura mater during neurosurgery preventing the loss of cerebrospinal fluid.
Another study reported that the persistence of the post-operative subdural cavity is a risk factor for reaccumulation of the hematoma and the presence of postoperative residual air
prevents reduction of the cavity20.
This leaves the residual air
that has passed through the separation process with appropriate enhanced levels of O2 content.
