Abstract
A medical placeholder. The medical placeholder has at least one hollow body which is expandable and which defines an interior space, a gas infeed hose which is connected or connectable in a gas-permeable manner with the interior space of the hollow body, and a gas discharge hose which is connected or connectable in a gas-permeable manner with the interior space of the hollow body. The hollow body consists partly or completely of at least one plastic material which is permeable to oxygen and carbon dioxide. A one-way valve is arranged in the gas infeed hose and a pressure relief valve is arranged in the gas discharge hose. Also disclosed is a method for gas-flushing a surface of a medical placeholder.
Claims18
A medical placeholder comprising:
- a hollow body which is expandable, defines an interior space in the interior of the hollow body, and a part of the hollow body or the hollow body fully consists of at least one plastic material that is permeable to oxygen and carbon dioxide;
- a gas infeed hose which is connected or connectable in a gas-permeable manner with the interior space of the hollow body;
- a gas discharge hose which is connected or connectable in a gas-permeable manner with the interior space of the hollow body;
- a one-way valve arranged in the gas infeed hose;
- and a pressure relief valve arranged in the gas discharge hose;
- wherein the hollow body or the at least one plastic material of the hollow body has a permeability coefficient for oxygen of greater than or equal to 0.5 cm3/(m2*d*bar) and a permeability coefficient for carbon dioxide of greater than or equal to 0.5 cm3/(m2*d*bar).
