Have you been struggling with compression stockings? Difficult to put on, uncomfortable?

No more!

The Pneumatic Therapeutic Stockings are very easy to put on, very comfortable and have exact compression pressure.

Easy to put on: Just wrap around the leg, fixate the velcro and inflate the stocking up to its preset pressure. No force is required. To take off, deflate the stocking and undo the velcro.

Hygienic:The PTS is made from a lightweight, hygienic material. The smooth surface is very easy to clean, just wipe a wet tissue or towel.

Fits under garments:The TPS can be worn under trousers or stockings. The specially designed valve is very flat and does not hinder movements or get caught in trousers or dresses.

Effective: the digital pressure sensor is preset for your ideal compression pressure. Inflate until the green light comes on. If during the day your legs get thinner, just check with the pressure sensor and add air if necessary. Perfect pressure for optimal results.

Comfortable: Do you feel the pressure when you put your leg into a swimming pool? No? That is exactly the pressure you feel when wearing TPS. Due to the perfect pressure distribution there is no sensation of pressure. These stockings are extremely comfortable to wear.

Why pneumatic compression is better

Compression has been used for a long time to combat the effects of venous insufficiency. These effects range from benign varices to ulcers (open skin). Traditionally, the compression is delivered via bandaging or elastic compression stockings.

These traditional methods have a few drawbacks:

  • Hard to put on, often requiring assistance from a nurse or caretaker
  • Imprecise amount of pressure
  • Uneven distribution of pressure
  • No pressure on parts of the ankle
  • Higher classes of compression require custom made solutions
  • Not adjustable

Pneumasox provides a solution without all these drawbacks:

  • It is easy to put on: just close the Velcro and pump it up.
  • Exact amount of pressure
  • It adapts to the shape of your foot and leg, so the pressure is evenly distributed and applied everywhere.
  • No need for custom made products
  • Easily adjustable pressure

How does it work?

Air pressure is by nature equal everywhere on all sides. If you fill a balloon the pressure on the rubber is the same on all sides of the balloon.

Pneumasox has an air compartment that you fasten around your leg and ankle with a Velcro strap. You then pump air into the compartment until the pressure indicator gives the signal that the correct pressure is reached.

Because air pressure is the same on all sides, the pressure on your shin is the exact same pressure as the pressure on the part just below your ankle.

The more technical explanation for physicians

The treatment of venous leg ulcers is based on the correction of the venous hypertension. This can be achieved by conservative therapy such as compression, and stimulating the calf muscle pump. On the other hand invasive methods such as surgery, endovenous thermal ablation and duplex guided foam sclerotherapy treat the venous insufficiency and ulceration.

Compression therapy is the first option and still the cornerstone therapy with the most proven efficacy (grade 1A) in recent guidelines. [1] It improves the pump function of the calf, reduces the venous volume, oedema and the venous diameter, and it increases the venous flow, the arterial perfusion and the microcirculation.[2]

It is very important to choose the most efficient and the most patient-friendly compression modality. Evidently, inelastic compression material is superior to elastic material, but it requires very well skilled people to put the bandages correctly. On the other hand, elastic compression therapy has proven also to be efficient in the treatment of venous ulcers by reducing the capillary leakage and oedema.

But it is difficult to reach the correct pressure gradient during the walking and rest position with elastic material to attend the hemodynamic effect. This problem results in wide variation of elastic stockings with different sizes, pressure and stiffness.

Stockings for venous leg ulcers require at least 40 mmHg and a high stiffness. But to put such stockings in the older population with chronic venous disease is demanding and the compliance is poor.  So a compromise is born. A compression with air filled stockings

Despite several variations, elastic and non-elastic stockings, bandages, wrap around stockings, most have some fundamental problems:

  • The pressure is not known. Due to variations in size, materials, shrinking of the leg, the person putting bandages on, sagging stockings or bandages, the actual pressure can be far from the prescribed pressure.
  • Made to measure stockings are expensive but are required for higher pressures.
  • Uneven pressure over the leg.
  • Difficult to put on, in many cases the patient cannot do it him/herself. For a nurse it is hard work.
  • Compliance might be low due to the difficulties.

The TPS is designed to remove all these issues.

By using air as the compression medium several of the above mentioned problems are solved. The pressure can be controlled exactly by the use of a digital pressure sensor. As the air chamber has only one compartment, the pressure will be exactly the same over the whole surface of the stocking. That also results in a very comfortable stocking. By inflating the stocking when it around the leg, it is very easy to put on. The adjustable fasteners allow for some variation in size, the amount of air needed will make up the remainder to have perfect fitting stocking without the need for made to measure. During the course of the day, the patient or nurse can easily control the pressure and adjust if necessary. It is even possible to deflate the stocking, for instance when lying down, only to inflate when standing up again.

The use of TPS vs the traditional stockings or bandages will substantially decrease the cost of compression therapy. The stocking itself is less costly by design, material in the limited number of sizes. In many cases the nurse is no longer required to put on the compression and where still needed, she can do her work faster and with much less effort.

The advantages

  • Perfect pressure. The pressure can be set to an exact value in mmHg.
  • The pressure is exactly equal on all locations on the skin, also in different regions such as the malleoli, the typical region where the ulcers are very chronic.
  • Non-allergic material

Indications:

  • Venous ulcers
  • Chronic venous disease
  • Compression after phlebectomy, endovenous thermal ablation, sclerotherapy and duplex guided foam sclerotherapy
  • Dependency syndrome, impaired calf muscle function

Contra-indication:

  1. ABI < 0.8 or > 1.3 ( Diabetes, polyneuropathy)
  2. Immobility

It does not stop here. We have many ideas to further develop the TPS. Think of variable pressure. Automatic pressure increase when standing up. Constant pressure monitoring to get precise data for better studies.

About us

Pneumasox is founded in 2017 to develop and produce compression garment based on air pressure.  The idea of an air stocking was ventilated by dr. med.  Micheal Kockaert, a dermatologist and phlebologist, and now working as an established phlebologist in Zürich and Lausanne. with extensive experience in phlebology.and  Ir. Toine Stokbroekx, founder of Tobrix and very familiar with phlebology as a manufacturer of endo venous laser disposables, took the basic idea and developed it into the TPS. The TPS system is tested at the University of Zürich at the department of phlebo-dermatology.

Pneumasox is based in Waalre, NL.
