TECASORB / Treatment of chronic wounds

TECASORB sterile adhesive plaster

Indication

TECASORB sterile adhesive plaster is a textile elastic fabric on which there is placed a pad of active carbon. It is used in dermatology, surgery and during first aid to cover minor wounds, abrasions, ulcers, wounds from insect bites (in such cases it is recommended to dampen the carbon layer before application).

It is also used in dialysis to cover wounds after removal of dialysis needles where it accelerates “squeezing“ during dialysis procedures and improves subsequent healing (in this case it is used in dry state).

An advantage of the product is its high absorption efficiency, further rapid pain relief in a wound and a highly efficient anti-infective barrier.

Product features

It prevents bleeding.
Anti-infective barrier – it acts against harmful bacteria.
Analgesic effect – it reduces pain sensation in a wound.
Detoxifying effect – it takes up toxins coming up e.g. from insect bites (a sting). If the conditions of wet healing are observed, transcutaneous „aspiration” – in the real sense of the word – of, e.g., insect toxin even from deeper layers of the skin occurs.
It significantly reduces the time of pressure coverage of a wound after removal of the dialysis needle.

Material used

Elastic fabric, adhesive, carbon pad, cover paper layer.

How TECASORB adhesive works

The adhesive plaster consists of a textile elastic carrier coated with an adhesive. The carbon textile is in principle a black sorbent, which is formed during thermal processing of hydrate-cellulose fiber. With a special carbonization technology, this textile gains high absorption capacity, which is reinforced by using of a non-woven textile layer. The result is a soft, pliable pad that can adapt to unevenness of the body surface very well. The application of the adhesive plaster is very easy and quick, removal from the wound is also trouble-free and causes no trauma.

TECASORB sterile carbon absorbent dressing

Indication

TECASORB is an absorbent, porous and permeable dressing with a layer of active carbon suitable for absorbing of organic substances, microorganisms, toxins, and unpleasant odor. TECASORB is classified in the category of covering compresses. Therefore, it is used as a disposable covering of acute and chronic wounds. But its advantage is also high absorption efficiency, it has a strong impact on accelerating stopping of bleeding, quickly reduces sensation of soreness in a wound and creates a highly efficient anti-infective barrier. All this occurs without using any medication, only due to physical properties of the assembly used.

Thanks to its unique production technology it is thus suitable as natural antibacterial protection for cleansing of infected, non-healing chronic wounds (especially leg ulcers, bedsores, skin problems associated with diabetes and other similar ulcerative surfaces).

TECASORB is also excellent for stopping bleeding, especially in fresh injuries bleeding from capillaries and smaller vessels, in surface injuries of skin cover, in bleeding from intraoperatively disrupted adhesions or during surgery on parenchymatous organs. It can be used also as a first aid for gunshot and stab injuries within applied compression.

The product is also suitable for use in home conditions, no special nursing skills and abilities are necessary. For most patients, simple training with a demonstration and basic guidance not exceeding five minutes is sufficient to master the issues of self-treatment. Stabilized wounds, in most cases, no longer require any additional cleansing during changes of dressing, except for wounds, where the infection has not yet been controlled with generally administered antibiotics.

Product features

Effective treatment of early infections – it efficiently cleans wounds and supports their faster healing.
Bacteriostatic effect due to creation and maintenance of a specific microclimate in a wound – it reduces the risk of sepsis, helps to prevent secondary infections.
Detoxifying effect – it actively captures microorganisms and chemical substances, takes up endotoxins originating in necrotic tissue. This effect occurs very quickly and is massive.
Stimulation of healing – TECASORB not only cleans the wound on a long-term basis, but literally sucks all free substances out of it, which is the essence of wound healing stimulation. Lack of nutrients and newly formed „free space“ thus leads to induction of neoangiogenesis, granulation and epithelialization. Although active covering does not deliver anything to human body, it creates a clean space for application of all natural healing mechanisms inherent to the body.

Material used

TECASORB dressing is made of several layers. The upper layer is from a non-woven textile made of a mixture of viscose and polypropylene, with a carbon fabric underneath.
The product is complemented with a folded gauze compress, which is freely included and serves to increase the absorbency of the product.

How TECASORB dressing works

When applied to the wound, the inert, nonallergiing carbon textile absorbs fluids from a wound very quickly. The final effect of this action is haemostatic. The carbon textile, together with a layer of non-woven textile, which is very tightly connected to the carbon textile, causes a strong diffusion process, in which acid metabolites and free radicals are continuously aspirated from the wound. This enhances the antiseptic capacity of the dressing. At the same time, the pain sensation is reduced.

Carbon textile is in principle a black sorbent, which is formed during thermal processing of hydrate-cellulose fiber. With a special carbonization technology, this textile gains high absorption capacity. Purity of carbon is 99.9%. Using a sophisticated construction, we obtain in fact a soft, pliable bandage that can be shaped, cut and is highly adaptable to unevenness of the body surface. Its application is very easy and quick, removal from the wound is also trouble-free and causes no trauma. Patient comfort and painlessness are maintained during changes of dressing. TECASORB contributes significantly to wound cleansing by creating of adequately moist environment and generally accelerates the healing process.

The medical device TECASORB based on microfilamentary activated carbon potentiated by the effect of diffusion pump provides optimum conditions for harmonized healing of wounds that are otherwise difficult to heal. By significantly speeding up the process of hemocoagulation it helps to stop bleeding and reduces penetration, expansion and effect of exogenous toxins in a body.

Basic indication areas of TECASORB bandage:

In relation to the area of indication, the methods of treatment must be also clearly differentiated:

Treatment of acute bleeding wounds where significant speeding up of stopping bleeding is in the forefront of action – here the TECASORB medical products are applied dry, often only as short-term compresses.
Treatment of wounds that are difficult to heal where mainly the sorption function applies while respecting the principles of “wet healing”.
Treatment of injuries with the presence of an exogenous toxin. It is necessary not only to apply the compress, but also consider the temperature of the applied cover according to the thermal stability of the toxin.

The TECASORB medical devices used for complex wound care are fundamentally different from conventional devices used in similar indications. The main differences are as follows:

The bioactive carbon is applied for a particular period of time when gradual saturation of the total absorption capacity of the carbon layer occurs. The length of this period depends on the phase of wound healing, the level of toxin contamination, the status of infection or colonization by microorganisms, and the amount of exudate produced by the wound/defect.
It is in direct contact with tissues. Considering absolute purity and chemical character of this effective detoxification device and sufficient cohesion of carbon microfibers it is not necessary and also not functionally desirable to separate this form of bioactive carbon by any barrier, such as semipermeable membranes, from the environment where it should be acting, as it is common in case of majority of other products based on activated carbon that show either lower purity of carbon substrate or inconsistency of its form.
Effect on tissue and the wound/defect environment is a complex of chemical and physical action, in which different functional mechanisms given by the microstructure and nature of the material apply in varying degrees according to the nature of the wound.

Why activated carbon?

Activated carbon (adsorption carbon) is a product made from coal, wood or peat¹. It has a porous structure and a large internal surface (400–1 500 m²/g) and can adsorb a wide range of substances, thanks to which it is used both in industry within various filtration processes and in modern medicine for the therapy of acute diarrhea, in case of acute intoxication, when it prevents the absorption of a poisonous substance into the body, and also as an absorbent dressing in the treatment of superficial and deeper wounds².

The sharp rise in the level of knowledge over the past two decades has enabled the construction of a new generation of dressing materials that use the unique properties of special forms of activated carbon collectively referred to as potentiated microfilamentary bioactive carbon. Among other commonly used forms, it stands out for its chemical purity and significantly greater absorption capacity. This form of bioactive carbon is one of the two basic raw materials of the active double layer of TECASORB dressing, which is intended for wide use in human and veterinary medicine.

Physically and chemically activated carbon does not directly participate in the metabolic processes taking place in an organism by supplying it with foreign substances or inducing the formation of substances previously absent in the body. Its bioactivity consists in the ability to physically and chemically bind a wide range of substances and particles present in the wound that are not desirable there. From the point of view of healing, bioactive carbon is able to influence the behaviour of the tissues with which it is in direct contact, thanks to its extremely large surface area and physicochemical properties. Due to the generally known properties of activated carbon as a detoxifying agent, it is unlikely that it could have a toxic or irritating effect on living tissue.
