What is Negative Pressure Wound Therapy?
The negative pressure wound therapy is a modern procedure, which is suitable for different types of wounds (chronic, acute wounds). The therapy ensures the safe removal of the wound exudate or the promotion of wound healing due to the formation of the so-called granulation tissue.
What actually happens?
Vivano from HARTMANN builds up a controlled negative pressure on the wound in order to transport excessive fluids and pathogens out of the wound and thus keep it clean.
Simultaneously, water retention is removed, leading to the reduction of swelling. As a result of the negative pressure, the wound dressing maintains a tight contact to the surface of the wound and seals the wound.
The blood supply to the wound increases and supplies the new tissue. The formation of granulation tissue is visible after a few days.
What are the components of Vivano?
1) VivanoTec unit is the source of the negative pressure.
2) VivanoTec exudate canister collects the excess fluids from the wound.
3) Hydrofilm tightly seals the wound.
4) VivanoTec Port connects the unit with the wound.
5) VivanoMed Foam is the wound dressing.
Must I stay in the clinic until I recover?
portable. You can continue the effective
negative pressure wound therapy in your home
environment as your physician is able to check the
Vivano has a day and a night mode. This means that the device reacts independently to the light conditions in the room.
In storage battery mode, the displayed images switches off after 5 minutes, the therapy continues normally. If the ambient light in the room is low, the background screen in the display becomes dark.
In mains power mode the displayed image does not switch off. If the ambient light in the room is low, the background screen in the display becomes dark. The dark background allows you to get a good sleep at night without a disturbing light source.
Please position the device ensure that it will not fall down while you sleep. Please ensure that the tubes are not bent or squeezed.
If you charge the device overnight, you will have a full storage battery at your disposal during the daytime with up to 16 hours operating time.
Insert the mains charger into the charging socket of the Vivano device.
Connect the mains charger to the enclosed mains cable.
Now insert the mains plug into the mains socket.
You should also observe: The mains cable is not suitable for countries with a power supply deviating from the German standard (220 Volt). The negative pressure unit then displays the moving symbol in the screen for the battery charge status, the storage battery is being charged.
Yes, your wound is protected against water drops by the transparent film. You can take a short shower with the dressing if your physician or nursing staff have no objections.
You should also observe the following information when you take a shower:
The device must not come into contact with water!
It must be positioned outside the shower cubicle and must not fall down.
Never shower with the mains charger connected!
If the device does get wet, in spite of these precautions, dry it immediately with cloth and check that it is still functioning without delay.
Notify your physician or nursing staff immediately if your Vivano is not functioning after coming into contact with water. The success of the therapy could be impaired in case of malfunction.
When you are drying yourself, be very careful with the dressing and only dab it. It must not slip or be damaged.
No, do not bathe with Vivano.
You may clean the surface of the device with a soft, moist cloth.
Do not attempt to clean the device beyond these measures. Get in touch with your attending physician or nursing staff if the device has to be cleaned.
General notes / information: Be very careful with the transparent composite film: it is very thin and can easily be damaged by sharp objects or by the claws and teeth of pets.
With Vivano, you are mobile in spite of continuous therapy and can move freely. Just put on the belt after you have attached it to the portable unit.
Which information must I observe?
When should I contact my physician or nursing staff?
- If an alarm message appears (except “storage
battery discharged” alarm).
- If there is a considerable change in the wound fluid,
e.g. if a lot of wound exudate is discharged within a
short time or if blood is visible in the canister.
What must only be carried out by authorised specialists?
- Replacement of the exudate canister.
- Cleaning the device.
- Changing the dressing.
- Making adjustments to the device,
especially affecting the therapy.
The granulation tissue appears soft and reddish and has a grainy (granulated) surface. In a healing wound, the granulation tissue is formed as a temporary covering and is the basis for the formation of the new skin.
Excretion from the wound is defined as wound exudate. It is purulent if it contains a high proportion of cells and cell debris. Wound exudate is formed as a result of inflammation, in case of infections or tissue injuries for example. The body attempts to excrete pathogens and dead tissue in this way.
Chronic wounds are skin wounds for which the healing phase lasts longer than two months in spite of appropriate treatment. This includes e.g. the pressure sore, the diabetic foot and the ulcerated leg.
