The ostomy collection bag is a flexible container for collecting body effluents through a stoma. 

The PROTEA VITAL DVF3L is a unitary (with one piece) ostomy collection bag with emptying (with discharge, open-end or drainable) – with Velcro closure. All components of the product are removed from the body once the bag is changed. This ostomy collection bag allows the discharge of effluents by means of a special portion for emptying, which closes-opens with a Velcro system.

Protea Vital products can be sold in this online store only to companies. The seller of the products is Theranova Protezare S.R.L.

The ostomy collection bag PROTEA VITAL DVF3L consists of several layers (films or foils) that are welded along the perimeter, as follows:

  • Starting from the body side to the outside, the first component of the pouch is a connecting element, called flange or wafer. The flange is made of hydrocolloid material and is welded by the following two films, respectively by the barrier film and the reinforcement film. The flange, together with these two layers of which it is welded, has an opening that surrounds the stoma. It ensures the attachment of the entire pouch to the patient’s abdominal area, respectively to the perimeter area of the stoma.
  • The first layer is the interior comfort layer made of non-woven material.
  • The second layer is the bag foil of itself.
  • The third layer is the reinforcement film and has the role of reinforcing the welding of the flange to the first two layers.
  • The fourth layer is the impermeable foil. It has three incisions made in the upper part to allow the relieve of gases, released by the body effluents, into a compartment from where they will be filtered and subsequently evacuated to the outside.
  • The fifth layer is the outer pouch foil. This foil has a filter welded inside at the top of it. The filter has an incision made on its outer part that ensures the evacuation to the outside of the gases released by the body effluents. To ensure a proper operation of the filter (e.g. if it is wet from the outside), a protective patch of Gore-Tex type of material is welded to its incision.
  • Between the second and fifth layer, the so-called collector compartment for body effluents is generated.
  • Between the fourth and fifth layer, the so-called filter compartment, mentioned above, is generated.
  • The sixth and seventh layers are outer comfort layers, they are in direct contact with the outside, respectively with the patient’s clothing. These layers, on the one hand, obturate the content of the bag providing discretion, and on the other hand, because they have an area where they overlap, they provide a pocket (a flap) for inspection.
  • Due to the fact that the ostomy collection bag PROTEA VITAL DVF3L is a bag with emptying (with discharge, open-end or drainable) it has an opening in its lower part that allows the discharge of the body effluents.
    • For opening in order to empty the bag, and then closing the PROTEA VITAL DVF3L ostomy collection bag in easy, hygienic and secure conditions, it also has the following elements at its bottom:
    • Finger pocket. A reinforcement strip positioned outwards (towards the clothing) and welded at the lower end of the bag opening, on the outer pouch foil, generates the so-called finger pocket. At the same time, also at the lower end of the bag opening, but this time inwards (towards the body), on the barrier film (interior pouch foil) are glued two polyvinyl chloride (PVC) strips. Thus, by placing the reinforcement strip and the two PVC strips in opposition, respectively by simultaneously operating them, with the help of the fingers, it is allowed to empty the bag in hygienic and secure conditions.
    • Velcro (hook and loop) closure system. After evacuating the contents of the bag, respectively sanitizing its opening, this opening is rolled upwards and the firm closure of the bag is ensured by means of the Velcro (hook and loop) closure system.
    • Velcro pocket. For reasons of ergonomics and safety, the opening of the bag once rolled and closed with the Velcro closure system, is further rolled upwards and inserted into the so-called Velcro pocket. This pocket is placed at the bottom of the bag and represents a space delimited by the outer pouch foil and the outer comfort layer, respectively a reinforcement strip that is welded by the latter.
