Pithos antechamber for hospital rooms
Pithos by Intelligent Care (Incare) is a mobile isolation antechamber that attaches to the door frame of a hospital room to isolate patients with airborne diseases.
What is the Pithos mobile isolation antechamber?
Pithos is a mobile isolation antechamber: a mobile biocontainment system that attaches to the existing door frame of a hospital room and turns it into a protected isolation room.
It creates a safe, isolated environment for patients with airborne diseases such as tuberculosis, measles and Covid, and at the same time prevents or minimizes the escape of contaminated air when doors are opened and closed. The doorway is the weak point of a conventional room; Pithos places a controlled space in front of it.
Intelligent Care (Incare) is part of Stretchers Industries OOD, a manufacturer based in Sofia, Bulgaria, and supplies hospitals and healthcare providers across Europe and beyond.

How does Pithos work?
Pithos adds a filtered buffer space between the patient room and the corridor, so that opening the room door no longer exposes the corridor directly to contaminated air.
Its filters and air systems give the patient a constant supply of fresh, clean air and trap potentially harmful particles, preventing them from spreading beyond the isolation unit. Inside, an ultrasonic disinfectant nebulizer provides an additional protective barrier in case personnel enter unintentionally without adequate personal protective equipment.
Antechambers are part of the airborne isolation measures in the CDC Guideline for Isolation Precautions. Our guide to negative and positive pressure isolation explains how pressure differences keep air moving in the right direction.

Where it is used
The mobile isolation antechamber is used on standard hospital rooms that need to host patients with airborne infections, either as a permanent upgrade or as a temporary solution.
Pithos lets a facility increase its biocontainment capacity without rebuilding rooms. A Pithos isolation chamber supplied by Stretchers Industries was commissioned at the University Multidisciplinary Hospital for Active Treatment of Infectious and Parasitic Diseases "Prof. Ivan Kirov" in Sofia, Bulgaria's national reference center for the diagnosis, treatment and control of infectious diseases.

Where a complete room has to be created from scratch, the Pandora modular room is the alternative.
