RUCK ViroCap Cold Plasma represents state-of-the-art podiatry at the highest level. As a portable cold plasma device for everyday practice use, it combines innovative medical technology with maximum user-friendliness. This active medical device generates what is known as cold atmospheric plasma (CAP) and specifically aids in the reduction of fungi and bacteria in dermatological nail and skin conditions. Efficient, safe and seamlessly integrable into your treatment workflow. The hygienic, single-use spacer delivers maximum efficacy without any loss of plasma, guaranteeing uncompromising hygiene and confidence with every application.

This is what makes RUCK ViroCap cold plasma so impressive:

  • Standardised approach: Efficient treatment with an average of 6–12 sessions.
  • Short treatment times: Just 1 min (skin) or 2 min (nail) – suitable for streamlined practice workflows.
  • Audible signal: 30 seconds
  • Pulse: For uniform and controlled surface treatments.
  • Disposable spacers: Defined spacing for reproducible results, maximum hygiene and targeted plasma delivery – without cross-contamination.
  • Portable system: Flexible handpiece with charging station – up to 45 treatments per battery charge, perfect for the practice and home visits.

Suitable for use by alternative practitioners specialising in podiatry, or as a complementary treatment for podiatrists and foot care professionals:

Why use cold plasma in podiatry and foot health?

Cold plasma is a modern, pain-free technology designed to help reduce bacteria on the nails and skin. This physical treatment can support antibacterial, antiviral and antifungal processes – even in hard-to-reach areas. The contactless application is gentle and can support the physiological regeneration processes of the tissue. For podiatrists and alternative practitioners specialising in podiatry, this means: better treatment outcomes, higher patient satisfaction and a clear innovative edge in day-to-day practice.

How cold plasma works, using nail fungus as an example:

1. Formation of cold plasma

Cold plasma is formed thanks to the ionisation of air using electrical energy at approximately 40 °C. It is a highly reactive, electrically charged gas that is effective without causing thermal stress.

2. Mechanism of action: Plasma against microorganisms

The plasma generates reactive oxygen species (ROS) and reactive nitrogen species (RNS), which specifically inactivate microorganisms, damage cell structures and alter the local environment – yet sparing healthy cells. The reactive oxygen species (ROS) and reactive nitrogen species (RNS) formed in the process can penetrate the skin and nails, where their physical effects support microbiological processes and the body’s natural regenerative mechanisms along with other processes.

3. Regeneration and healthy nail growth

Cold plasma can promote microcirculation, blood flow and cell regeneration. It supports regeneration along with healthy nail growth and can be optimally integrated into complementary treatment plans.

Cold plasma explained step by step, using nail fungus as an example

1. Preparing for treatment

Put on personal protective equipment and, to proceed, carefully prepare the affected nail using a diamond bur.

2. Preparing the device for use

Unpack the disposable spacer in front of the patient and slide it fully onto the device so that it sits securely – the device is now ready for use.

3. Select treatment duration

Set the treatment time due to nail fungus to 2 minutes. Up to 10 treatments of 2 minutes each are possible per session or per spacer. So that all 10 toes can be treated with a single spacer, up to 10 treatments of 2 minutes each are possible.

4. Targeted use of plasma

Press ‘Start’ and have the spacer just above the nail. If necessary, lift the nail fold lightly or position the drill in a gooseneck configuration.

5. Ensure hygiene

Dispose of the spacer after treatment, clean and disinfect the device in accordance with the instructions, and then put it in the charging cradle.

6. Practical ways to complement therapy

Cold plasma and AntiMYX tincture complement each other in their directions and, when used together, can reinforce the therapeutic effect.

Did you know?
Not all cold plasma works in the same way

Cold plasma has established itself as a modern method of germ reduction. In practical application, however, it is evident that ROS results often vary. A crucial factor here is the plasma source. The ViroCap utilises the piezoelectric effect and a unique ceramic rod, enabling energy to be transferred to the tissue in a targeted and efficient manner. With diffuser systems, on the other hand, a large proportion of the energy is lost before it reaches the nail. This results in significant energy wastage, minimal effectiveness and treatment outcomes that are difficult to replicate.

More control. Greater efficiency. Greater impact at the target site.

Frequently asked questions and answers

What is the RUCK ViroCap cold plasma used for?

The RUCK ViroCap cold plasma is a mobile medical device for reducing bacteria, viruses and fungi in dermatological skin conditions by means of cold atmospheric plasma. It is used in combination with the appropriate single-use spacer by medical professionals.

Who is permitted to use the RUCK ViroCap cold plasma?

The device is intended for professional use. Users are physicians and medical professionals — for example in clinics, doctors' surgeries, podiatric practices, care facilities or in mobile use. Before use, all users must read the instructions for use carefully and familiarise themselves with the device.

Which patients is the application intended for?

The application is intended for patients with dermatological skin conditions as well as superficial skin and nail disorders in the podiatric field of use. Patients should be at least 12 years of age.

Which fields of application are intended in the podiatric setting?

In the podiatric setting, the field of application in particular covers the skin of the foot, toes, spaces between the toes, toenail surface, nail fold, nail bed area and the nail itself.

What does the RUCK ViroCap cold plasma system consist of?

The system consists of the handset, the plasma module, a single-use spacer as well as the charging station with power supply unit. The components can be safely stored and transported in the case.

Can the device be charged with a single-use spacer attached?

No. Please remove the single-use spacer before charging. The handset cannot be charged with a single-use spacer attached, and the spacer becomes unusable.

What is a single-use spacer and what is it used for?

The spacer is a single-use item inserted into the front of the handset. It ensures a safe distance between the plasma module and the treatment area, protects against unintentional contact with the plasma source and forms a hygienic interface with the treatment area.

Can I reuse a single-use spacer?

No. The spacer is a single-use item and may only be used for one patient and one treatment area. Reuse is technically not possible and can additionally lead to cross-contamination.

How many applications are possible with a single-use spacer?

Once attached, up to 45 applications per battery charge are possible with the spacer. Within this period, up to 20 applications of 1 minute or 10 applications of 2 minutes each are possible. After this period has elapsed or after the maximum number of applications has been reached, the single-use spacer is automatically deactivated.

Do I need to wear gloves during the application?

We recommend wearing gloves at all times when using and cleaning the device. This serves your own protection and helps to prevent cross-contamination.

How do I clean and disinfect the device after use?

First remove and dispose of the single-use spacer. Clean the accessible surfaces of the handset with a damp single-use wipe, thoroughly dry all cleaned parts and disinfect the accessible surfaces with a suitable disinfectant wipe. Observe the contact time, concentration and temperature specified by the manufacturer of the disinfectant.

How do I store the RUCK ViroCap cold plasma correctly?

After use or when not in use, place the handset in the charging station. Remove the single-use spacer beforehand. Please note that the plasma source is made of sensitive ceramic and can be damaged if dropped.

What is the service life of the system?

The handset and the plasma module have a service life of at least two years from first use, provided the device is used and maintained in accordance with the instructions for use. The plasma module is replaceable and can be purchased separately.
