Medical coverage for closing wounds of various etiologies
intelligence
The coverage of “OTRAN” is currently at the registration stage.
base
composition
The coating is a two-component polyurethane foam composition in packaging of
aluminized polyethylene.
The coating is obtained by mixing two components:
• polyol (with the addition of nanocrystalline boehmite);
• isocyanate,
The foam mass, when applied to the wound, forms a fine-porous elastic coating
with a thickness of 0.8-1 cm. The coverage area depends on the volume of the
mixed components.

Prerequisites of creation
ТTraditional dressings (bandage, cotton wool and gauze) have significant drawbacks:
¡¡
trauma,
low hydroscopicity
decay in a wound, etc.
Modern dressings and coatings do not have these disadvantages, but not one of the coatings on the market is not
“ideal” or universal, because they either have a clear specialization in the type of wounds, or have some kind of
deficiency, for example, inconvenience in use (lack of adhesion to wound - the need to use additional fixing bandages
There are a number of requirements for the “perfect dressing” formulated by T. Turner in 1990. : *
To create and control the wound environment moisture optimum for healing;
Provide and control the optimal gas composition of the wound environment;
Maintain an optimal concentration of hydrogen ions (pH) in the wound;
To provide heat insulation of the wound from the external environment;
Be impervious to microorganisms on both sides;
Be non-toxic, do not contain substances or fragments that can interfere with healing;
Be atraumatic without causing pain or damage to the newly formed tissue or epithelium when changing the
dressing.
* - such requirements became the basis for the start of work to create a coating

Boehmite applicationsбемита
Nanocrystalline boehmite is currently one of the most sought-after and promising bases for the manufacture of heavyduty ceramics, leucosapphires, chip substrates, super-bright LEDs, fire retardants, etc.
Antacids (with boehmite
additives)
In the medical field, boehmite is most commonly used:
in ultra-fine filters;
as an antacid ("Almagel")
as a coating agent, filler, etc.
The choice of nanocrystalline boehmite as an additive is due to the known bioactivity of this substance as a sorbent with
full resistance to the ingredients of the polyurethane foam coating.
Nanocrystalline boehmite improves the

Nanocrystalline boehmite in the composition of the polyurethane

The inner surface of the micropores OTRAN is abundantly
covered with needle-shaped nanocrystalline boehmite, whose
fractal clusters have the properties of a biologically active
sorbent.
The sharp edges of the needle particles and plates of the
rhombic form of nanocrystals have a direct damaging effect on
the bacterial membrane. The possibility of such a direct
mechanical effect of nanoscale crystals on E. coli bacteria was
first shown by the University of Pittsburgh scientists in 2004

optimizes the course of the wound process in
patients with:
trophic ulcers
long-term non-healing, burn, gunshot wounds
and also actively affects the wound process in
patients with diabetes mellitus complicated by
diabetic foot syndrome

Excellent water and bio-insulation properties;
Excellent sorption properties;
No adhesion to wet surfaces with good adhesion to dry
surfaces;
Non-toxicity, self-sterilization when mixing components;
Absolute repetition of the relief of the wound surface;
Improved capillary blood flow in the affected area.

The influence of OTRAN on the healing process of burn wounds;
The effect of OTRAN on the healing of nonhealing wounds, trophic ulcers,
and other injuries of the skin.
The main findings of the research:
1
Polyurethane foam formed on the wound is non-toxic and has
moderate antimicrobial properties for most microorganisms that
are sown from the surface of wounds.

6
When treating patients with the use of OTRAN, there is a
noticeable increase in the regenerative abilities of tissues, which
leads to a reduction in the healing time:
• nonhealing wounds - for 34 days;
• trophic ulcers - for 46 days.
3
High efficiency of OTRAN coating has been proven in the
treatment of patients with superficial burns, the healing of which
occurs under it:
• for burns of the II degree - for 3 days;
• IIIA degree burns - 7 days earlier.
4С
In order to create the best conditions for tissue regeneration
and enhance the antimicrobial effect under the coating, the use of
various drugs, in particular Ximenedon, in the form of 5-10%
powder with 90-95% talc is shown as a pad.
OTRAN coating enhances capillary blood flow at the
site of its application.
The possibility of effective use of coating OTRAN for:
treatment of patients with pressure sores;
closure of donor wounds;
prevention of inflammatory complications of the soft
tissues around the needles for skeletal traction;
skin protection around gastrointestinal fistulas;
strengthen drains and catheters.

The coating of polyurethane foam can be successfully
applied in the military field conditions at the stages of
rendering the first medical, skilled and special assistance and
in emergency situations in the aftermath of disasters.

Also, studies have shown that the body's immune system, burned, treated with a coating, does not undergo any
pathological changes, the occurrence of which could be associated with the effect of the coating on homeostasis.
On the contrary, during the treatment with the help of the coating, the phenomenon of stimulation of neutrophilic
phagocytosis was noted in patients, which should be regarded as a positive phenomenon that helps patients to
better cope with the microbial flora remaining on the burn wounds under the coating.

Using
Acute and chronic wounds;
Burns;
Ulcers and long healing wounds.
Protect the wound from the penetration of water, oxygen
or bacteria;
Promotes tissue regeneration and granulation;
Helps reduce the acidity (pH level) of the environment,
which inhibits the growth of bacteria;
Convenient to use and wear;
Applicable for areas of great friction like heels and
sacrum;
Can be used for both wet and dry wounds;
Able to absorb only a small amount of exudate;
The process of evacuating the exudate is very slow;
Promotes tissue self-destruction, as it allows exudate
contact with necrotic tissue;
Destruction of the dressing can lead to discharge of
unpleasant color and odor;

Description
Ready sorption gel, fixed on a transparent semipermeable membrane;
The gel keeps the wound moist and at the same time
absorbs excess fluid, maintaining optimal conditions for
its healing;

bed is formed for the purpose of rehydration and
rejection of a dense necrotic scab or stimulation of
epithelialization of flat granulating (including donor)
wounds;
Wounds with poor content of exudate;
Using
Benefits
disadvantages
Due to the multi-layer structure of the gel with the
presence of a layer with pronounced sorption properties
and adjacent layers with high (up to 80%) moisture
content, these dressings can maintain the necessary
parameters of the wound environment for a long time
and stay on the wound surface for up to 14 days or
more;
Do not stick to the wound;
The outer surface is impermeable to microorganisms
and water;
The transparent structure of the dressing allows you to
visually monitor the condition of the wound at any time
without changing the dressing;
Relatively low sorption capacity
Therefore, secondary dressings are often required;
29

Very high absorption rate;
Promotes the evacuation of exudate from the wound;
Promote tissue regeneration;
Limited scope - only wounds with abundant exudate
content;
Used as a primary dressing and should be covered with
a gauze pad or a compress to extract excreta;
