  • the present invention provides a medical treatment device with a port which can advantageously satisfy the highest hygiene requirements placed on medical treatment methods.
  • the present invention advantageously ensures a germ-free environment at the connections between the disposable and the treatment device. This can help prevent germs from entering the patient's blood and thus increase patient safety.
  • errors can also be advantageously localized, which can make troubleshooting much easier. It is known, for example, that if a leak occurs at the patient connection between the disposable and the connector, compulsory disinfection after treatment or even a stop to treatment may be necessary. However, if the occurrence of a leak is detected by the hydraulics, as suggested here for some embodiments, then only (repeated) suction may be necessary. In these cases, the next treatment can be carried out without prior disinfection, which would previously have been necessary due to the leak. It may also be advantageous to avoid an unnecessary stop to treatment in these cases. This can contribute to improving the patient's well-being and may also help to save time and costs.
  • Another advantage is that the interior of the port is protected from contact by operating personnel. This also helps prevent or avoid the introduction of germs into the patient's bloodstream.
  • the flight of liquid droplets can be prevented or limited by leaving a gap between the connector and the housing when the connector is inserted into the through-opening of the port.
  • the formation of negative pressure which can arise when the connector is removed from the port, is thereby advantageously prevented or reduced.
  • the probability that droplets could fly due to the formation of negative pressure is consequently also reduced or prevented. Should droplets nevertheless fly, the droplets are intercepted by the protective tube, which can also represent a further advantage of the present invention.
