Treatment with the CPT®patch

The application of the dressing is simple and safe

For treatment, apply a CPT®patch to the wound area and operate it by means of the CPT®cube.

For treatment, apply a CPT®patch to the wound area and operate it by means of the CPT®cube.

1. open sterile packaging

2. remove CPT®patch

3. remove protective foil

3. apply CPT®patch

The treatment starts automatically after pressing the start/stop key on the CPT®cube. The treatment lasts 2 minutes.

The treatment can be repeated as often as necessary until the desired therapeutic success has been achieved. However, it should be noted that there should be at least 24 hours between each plasma treatment.

The treatment can and should be applied adjuvantly to other forms of therapy or recommendations of the corresponding guidelines at the discretion of the treating physician. Following plasma treatment, the wound is covered with commercially available wound dressings.

The effect

The treatment and the systems

How does a cold plasma treatment work? 

Cold plasma is applied to the affected area of the skin in a flat or punctual manner. The treatment is performed 2-3 times a week. Cold plasma treatment is a gentle, easy-to-perform therapy. It is performed without pain and with no or light skin contact. Two forms of cold plasma treatment have been used so far:

Hand guided systems

The hand-applied cold plasma devices with variously sized attachments (for single use) treat areas ranging from pinpoints to several square centimeters. There are pen-shaped to stamp-like solutions. What they all have in common is the influence of the practitioner on the treatment. Care must be taken to avoid over- or under-treatment. The applicators are sometimes grated through the wound in contact with the wound.

Automatic systems

The treatment starts automatically after pressing the start/stop key. The treatment runs at the optimum effect and ends automatically after approx. 2 minutes. Due to the automatic treatment, over- or under-treatment is excluded. The adhesive edge on the applicator has atraumatic properties and prevents direct contact with the wound. The treatment is also suitable for large-area wounds.

The type and duration of plasma therapy depends on the particular wound conditions. In severely necrotic or inflamed wounds, plasma therapy should initially be used to accompany wound debridement and possible local or systemic drug therapy.

The intensity of the plasma treatment is controlled by the duration of the session and is repeated two to three times a week.

After the third treatment with theCPT®patch you could see - the wound is starting to heal really great. I can't see the cold plasma, but it smells like fresh air and the treatment is the first one that really helps me.

Why does plasma therapy work for wounds?

Cold plasma destroys germs, improves oxygen supply in the skin, stimulates cell growth and promotes wound healing.

The most important mechanism of action of plasma in wound treatment is probably its strong antimicrobial and anti-inflammatory (anti-inflammatory) effect. Medical cold plasma is only 37 °C warm. Nevertheless, it kills viruses, bacteria, fungi or spores within a few minutes.

In addition, the cold plasma stimulates cell division (cell proliferation) and cell migration. These processes increase collagen synthesis and support physiological wound healing. Even in the case of long-standing chronic wounds, cold plasma treatment achieves good treatment results. Possible side effects or pain during treatment have not occurred so far.

We use cold plasma therapy and the CPT®patch for our difficult and poorly healing wounds as a supplement to classic wound care.

The active components explained

Active components (excerpt from position paper on risk potential and application perspectives of cold atmospheric pressure plasma in medicine, NZPM)

According to the current international state of research, the main active components of cold atmospheric pressure plasmas are reactive nitrogen and oxygen species (RNS, ROS), UV radiation and electric fields.

According to the current international state of research, the main active components of cold atmospheric pressure plasmas are reactive nitrogen and oxygen species (RNS, ROS), UV radiation and electric fields.

Reactive nitrogen and oxygen species (RNS, ROS) are formed locally and briefly by coupling electrical energy into gases that are not biologically active per se (argon, helium, nitrogen, oxygen, air and mixtures thereof) and subsequent interaction with adjacent media (atmospheric air, liquids, surfaces). In principle, the same reactive species are sometimes produced in the human body as part of normal metabolism and in some cases have important functions in controlling and mediating physiological and pathological processes. Briefly elevated doses of these RNS and ROS can be effectively detoxified by the body's own systems.

UV radiation is used medically in phototherapy and photochemotherapy, among other things. In this context, as well as under the aspect of general personal and occupational safety, also outside the medical environment, limit values have been defined for UV exposure, which are significantly undercut in connection with the use of cold atmospheric pressure plasma. 

Two important findings of basic plasma medicine research in recent years are:

1. biological plasma effects on cells and in tissues are mediated via changes in the fluid cell environment.

2. for biological effects induced by plasma action, oxidizing species, so-called reactive oxygen and nitrogen species (ROS, RNS), introduced into the liquid or formed in the liquid play a dominant role.

The same reactive species (ROS, RNS) are also produced in the human body as part of normal metabolism and in some cases have important functions in controlling and mediating physiological and pathological processes. The most important ROS and RNS are hydroxyl radical (OH-), hydrogen peroxide (H2O2), superoxide or hyperoxide (O2--), nitric oxide (NO-), nitrogen dioxide (NO2-) and peroxynitrite (ONOO-). They play an important role in wound healing processes, for example. This finding provides an essential scientific basis for the concept of plasma-assisted wound healing, in which, in addition to the well-known antibacterial/disinfectant plasma effect, stimulation of tissue regeneration is also to be achieved by plasma action. One mechanism of plasma action is thus based on the support of endogenous functions which - for example in the case of non-healing chronic wounds - cannot be sufficiently effective due to disease-related disorders. Furthermore, it is known that a certain basic concentration of RNS and ROS is always present in human cells. Due to the physiological occurrence of these species, short-term elevated concentrations can be effectively detoxified by endogenous systems [16-24]. Transcriptome analyses of in vitro plasma-treated human cells have shown that genes associated with the cellular stress response are increasingly upregulated and antioxidant active enzymes are produced as a result of plasma treatment [25]. 

Since plasma treatments are local and time-limited, under normal conditions the risk of side effects associated with entry of these ROS and RNS into the tissue is expected to be exceptionally low. 

3. ultraviolet radiation (UV radiation)

UV-B radiation in particular is used in dermatology as part of phototherapy. According to the recommendations of the German Dermatological Society (DDG) on phototherapy and photochemotherapy, initial doses of between 20 and 60 mJ/cm2 are recommended for broad-spectrum UV-B application (280-320 nm) depending on the skin type, and doses of between 200 and 600 mJ/cm/WTA are recommended for narrow-spectrum UV-B treatment (311 nm).

A comparison with solar radiation shows that the UV intensity emitted by the cold atmospheric pressure plasma sources used in clinical testing or approved as medical devices to date is far below that of sunlight.

For the plasma sources currently certified as medical devices, it has been shown that under the recommended conditions of use (working distance, treatment time), the maximum permissible daily UV dose is significantly undercut.

4. electric fields

Electric fields can first be divided into direct and alternating fields. Furthermore, the pulsation of such signals as well as a mono- or bi-phase modulation allows a high parametric diversity. Technical frequencies are in the range of a few Hz up to the GHz range. Devices that work exclusively with electric fields have been established for many years for use in and on the human body and can induce an electric current flow in biological tissue as a result of the electric fields. Regardless of the device, the use of electrical signals for electrostimulation offers a variety of proven applications in medical care. For example, cell movement of immune cells (macrophages and granulocytes) and migration of skin cells (keratinocytes) and corneal epithelium can be specifically influenced in response to an electric field, proliferation behavior of connective tissue cells (fibroblasts) is stimulated, and for new vessel formation (angiogenesis) and nerve growth, the electric field is also important. Finally, in vivo studies using electric fields have shown an antibacterial effect on both gram-negative and gram-positive bacteria.

In recent years, research in the field of bioelectricity has demonstrated significant links between endogenous electric fields and the wound healing process. A meta-analysis by Gardner et al. was performed using data sets from 15 clinical trials with the goal of quantifying the effect of electrical stimulation (ES) on chronic wound healing. Treatments with ES achieved an average wound reduction of 22.2% per week, compared with only 9.1% in control groups. In the published sub-results of Cochrane Review #077, healing success (wound closure) using electrical stimulation was compared to placebo control. This question was investigated in 13 of the 20 studies. The analysis showed that twice as many (OR=2.12; 95% CI: 1.55 - 2.90) wounds were healed by treatment with electrostimulation (verum) compared to controls.

At the current state of clinical research, no clinically relevant side effects are known.

Study situation on cold plasma

An extensive body of studies shows the effectiveness

The antimicrobial efficacy was confirmed by further studies. Chronic wounds of 34 patients were treated with cold plasma or in combination with a wound antiseptic. The combination therapy showed the best efficacy [1].

In a monocenter, randomized-controlled clinical trial, seven patients each with at least 12-week-old chronic ulcers underwent plasma treatment or no treatment in addition to normal wound care. The plasma source was a dielectric-restrained discharge powered by air. Wound healing occurred similarly to standard therapy, while wound areas colonized with bacteria decreased by a mean of 88% in wounds treated with Palsma [2].

In another study with five subjects, two artificial wounds were created on each arm using negative pressure and the healing process was observed. The four wounds received either no treatment (A) a treatment with cold plasma (B), Octenisept© (C) or a plasma treatment followed by a treatment with Octenisept© (D). Normalized to initial area, plasma-treated wounds (B) healed fastest at all measured time points, while untreated wounds (A) healed slowest [3].

Sixteen patients included in the study (ten women and six men) with chronic leg ulcers were each treated with cold plasma three times a week over a period of two weeks. In addition to measuring antimicrobial activity, the aim of the study was to investigate the effect on wound healing. 

The parameters compared were, in addition to the number of bacterial colonies per square centimeter, the size of the wound surface and the change in wound volume. The authors concluded that the immediate antimicrobial effect of the two treatment methods was largely comparable. Plasma therapy was very well tolerated by patients and, according to the authors, is unlikely to cause allergies due to its physical principle of action [4].

In a more extensive study with 70 patients, a tendency towards improved healing was determined on chronic ulcers treated with cold plasma - compared to untreated wounds [5]. In addition, another randomized-controlled trial with 40 patients showed significantly improved healing after plasma treatment of acute wounds after skin grafts [6]. A summary of the current status of plasma application in animal experiments, in vivo, and clinical studies and case reports is also the subject of a recent review [7].

A risk assessment with reference to plasma species (temperature, UV radiation and free radicals) did not reveal any increased risks for humans [8].

Based on the state of clinical research, plasma applications in dermatology as well as plastic and aesthetic surgery currently have the highest prospects of success. The use of antimicrobial plasma effects, plasma-assisted stimulation of tissue regeneration and inflammation-modulating plasma effects are the focus of therapeutic indications.

G-BA paves the way for reimbursement and decides on trial study

G-BA paves the way for reimbursement and decides on trial study

The evaluation procedure at the Federal Joint Committee (G-BA) for the treatment of chronic wounds with cold plasma has been ongoing for almost two years. Now (February 2023), the G-BA has decided in its plenary session to conduct a trial study for cold plasma therapy in chronic wounds for reimbursement. This clears the last hurdle on the way to reimbursement of wound treatment with cold plasma, from which millions of people in Germany alone could benefit.

In order for a health service to be reimbursed by the statutory health insurers in Germany, the Federal Joint Committee must first conduct an evaluation procedure and assess the medical and economic benefits of the therapy. For almost two years, manufacturers and leading wound experts have been driving the process for reimbursement of cold plasma therapy at the GBA. The decision to conduct the trial represents the most important milestone.

All participants in the plenary session at the G-BA agreed that cold plasma can positively influence the healing process of chronic wounds and will improve the quality of life of many people, as cold plasma therapy is superior to standard therapy. In addition to inpatient treatment, the focus is on the transsectoral treatment of chronic wounds in the office-based and outpatient setting.

"On July 15, 2021, the G-BA gave a positive decision on the application for a trial of cold plasma treatment for chronic wounds. According to this, the method demonstrates the potential of a necessary treatment alternative compared to standard wound treatment according to guideline recommendations. This assessment is largely based on the findings on the plausible and established surrogate endpoint change in wound size, which were taken from the studies supporting the application."

Body of the joint self-government
In Germany, the legislator makes the fundamental decisions on the entitlement to benefits of the statutory health insurants.
The legislator has entrusted the G-BA as the highest body of the joint self-government with the task of specifying the so-called benefits catalog of the health insurance funds according to the generally recognized state of medical knowledge. The Federal Ministry of Health is responsible for legal supervision.
The G-BA is formed by the four major self-governing organizations in the health care system:

  • National Association of Statutory Health Insurance Physicians
  • National Association of Statutory Health Insurance Dentists (KZBV)
  • German Hospital Federation (DKG)
  • Spitzenverband Bund (GKV-Spitzenverband)
    of health insurance funds

In accordance with the provisions of the Fifth Book of the Social Code, organizations that represent the interests of patients and self-help groups for chronically ill and disabled people at the federal level have the right to participate in consultations and submit proposals, but no voting rights.
The main task of the G-BA is to define the content of health care in more detail in guidelines and to decide which services are paid for by the SHI.
In this way, the G-BA fulfills its legal mandate to ensure that all patients with statutory health insurance can receive good care and benefit from medical progress. At the same time, its guidelines serve to ensure that care is provided in a quality-assured and economical manner.
