  • Overview

    Velseal™ is a sponge-based dressing for control of traumatic bleeding. The ready-to-use patch consists of sponge impregnated with clot promoting & stabilizing agents and a novel polyelectrolyte complex (PEC) of biopolymers. These constituents are held in the vesicular voids of the matrix, on the internal surface sponge. This means they are able to act rapidly when blood flows into the dressing. Once in contact with blood, the dressing promotes clotting and stabilization of wound surfaces.

  • Properties
    • A novel absorbent dressing to control traumatic bleeding
    • Ready to use patch containing clot promoting & clot stabilizing agents
    • Used on external wounds to stop even severe arterial or venous bleeding within 4-6 minutes
    • Increases the threshold time required to mobilize the patient safely to the hospital
    • Highly porous
    • Prevents secondary bleeding
    • Does not cause exothermic reactions
    • Non-cytotoxic, non-irritant & non-sensitizer
    • Biocompatible dressing
    • Non-adherent in nature
    • Proven highly effective in GUNSHOT WOUNDS
  • Action

    The interconnected small voids of porous PEC sponge provide a very large surface area for the flowing blood and hold the natural clotting agents. A large surface area and micro-areas exert a pseudo-catalytic effect on blood clotting. The body’s own whole blood coagulation cascade is activated. The blood clotting process occurs within the voids. Further in the presence of impregnated naturally derived clot promoting and stabilizing agents intensifies the clotting action & stabilizes the clot. Natural blood clotting continues right up to the injured blood vessel without affecting the flow characteristics of the circulating blood.

  • Application Method
    • Step 1: Open Dressing - Extract the sterile dressing from the primary packing
    • Step 2: Ensure that the correct side is used - Ensure that the side opposite to the marked side of VELSEAL™ is applied on the wound, i.e. the marked side faces upwards after the application.
    • Step 3: Apply directly on source of bleeding - It is critical to place the dressing directly on the source of the bleeding, the area where the blood vessel damage has actually occurred.
    • Step 4: Hold firmly until bleeding is controlled - Apply firm, even pressure on the dressing for 4 - 6 minutes.
    • Step 5: Lift and check - If bleeding has stopped after 4 - 6 minutes, else continue pressing.
  • Precautions
    • For external use only.
    • The dressing can remain in position until the wound can be treated properly.
    • Do not use if pack is damaged/or contents are wet. VELSEAL™ is supplied as a sterile, single-use dressing. Do not re-use. Do not re-sterilize.
    • If the first attempt at application of the VELSEAL™ is not successful, do not re-apply the same dressing, instead obtain a new dressing for re-application.
    • VELSEAL™ must be positioned properly to the bleeding wound /actual source of the bleed. Use promptly after opening. Don’t keep open for long time as it may absorb moisture and change property/reduce efficacy.
