Lymphatic system

Lymphatic drainage and good circulation are among the most important vital functions of the human body. Blood capillaries continually release a certain amount of blood fluid into tissues, which may be reabsorbed into the capillary blood stream.  The removal of this fluid from tissues and its return into circulation is the job of the lymphatic system, which is comprised of lymph vessels and lymph nodes.

Function of lymph vessels:

  • absorption of macromolecular substances, especially proteins, blood proteins and metabolic waste products, as well as cells, bacteria, and solid particles from tissues and transport into circulation
  • role of mechanical bumper ensuring tissue tension, especially at the level of blood capillaries and pre-lymphatic channels

Function of lymph nodes:

  • act as phagocytic filters, capturing, swallowing and absorbing foreign particles (cells, bacteria and other) and preventing the passage of pathogens into blood circulation
  • place of antibody formation, thus representing an important immunological component
  • creation of lymphocytes

Each day, the human body creates approx. 2 l of lymph (the fluid which comprises the content of the lymph vessels).   This amount of fluid is called the lymphatic load, which circulates through the lymphatic system. Under normal conditions in the body, the transport capacity of the lymphatic stream is several times higher than the “load” and the lymphatic circulation has a great functional reserve.

If for any reason there is a reduction in transport capacity to such degree that the functional reserve is exhausted and the load exceeds the transport capacity, there is an accumulation of macromolecular substances and osmotically bound water in the tissues.  This results in swelling – lymphedema.

Primary lymphedema is caused by a congenital disorder of the lymphatic channels. Secondary lymphedema may be caused by injury, infection, severing of vessels following an operation, or damage to vessels by a malignant process.  Lymphedema of any stage or etiology represents the final stage of lymphatic drainage impairment.  Edema occurs more often than supposed, up to 50% of the global population experiences some form of high protein swelling from time to time.

Instrumental pressotherapy

One of the ways to eliminate lymphatic disorders is instrumental lymphatic drainage or pressotherapy.

PNEUVEN devices with multi-chamber sleeves are designed for sequential compression drainage  (SCD) focused particularly on treatment of the lymphatic system disorders, which manifest as lymphatic swelling, cellulite, poor immune system function with accompanying symptoms of fatigue, etc.


The principle of instrumental pressotherapy is based on the controlled use of air to fill individual or at times overlapping chambers of particular sleeves to create a pressure wave, which causes a defined compression of the extremities or stomach, hips and buttocks.


The objective of the controlled pressure wave is to restore the function of the lymphatic system in affected areas and through regular application keep the affected area freely flowing, to reduce and in certain cases completely eliminate the causes of these disorders, which manifest as lymphatic swelling, and thus maintain the permanent mobility of the patient.  Aside from lymphotherapy, it is also possible to use pressotherapy in phlebotherapy for disorders of the venous system.


The device software makes it possible to turn on and off individual electrovalves, change the device parameters such as pressure in sleeve chambers, duration of chamber inflation, cycle length, pressure gradient settings, which is the change in pressure at the beginning and end of the cycle, etc. which modifies both the direction of wave action, its intensity and length of patient needs. Depending on individual types of devices, varying especially in the number of valves used, it is possible to select from the 86 basic massage, kneading and combined therapy programs.        

       The positive pressure waves used range from 3 to 6 kPa, exceptionally up to 10 kPa. The speed and direction of the pressure wave is controlled electronically through electromagnetic valves, which are connected by tubes and bring air from the source to individual sleeve chambers.  Instrumental therapy attempts to the greatest degree possible to complement or, for repeated standard procedures, even replace manual lymphatic massage, performed by an expert lympho-therapist.

     Aside from the effect of managed pressure, PNEUVEN devices are also used to create managed vacuums, especially when emptying the sleeves after finishing therapy.  It is also possible however to use the vacuum function for vacutherapy and microdermabrasion.

Lymphatic drainage is not only a widely acknowledged treatment method with a broad range of indications, but is currently also very popular for relaxation and cosmetics.  It aids in general regeneration and body detoxification, and improves metabolism and physical condition.

The proper use and safe application of  PNEUVEN  devices  is ensured by an accurate diagnosis and professional training of health care and beauty personnel
