Abstract
A single-use infection control system for a forced air warming machine having hosing connected to the machine including: a closable container having a chamber to receive the machine, the container constructed from air permeable material that prevents infectious airborne particles from entering the chamber; a sleeve having a first end and a second end, the first end engaged to an aperture on the container and the sleeve surrounding the hosing; and a filter cap constructed from the air permeable material, disposed at the second end and covering an opening of the hosing.
Core Innovation
The invention relates to a single-use infection control system for a forced air warming machine having hosing connected to the machine. A closable container is provided to receive the machine, and the container is constructed from air permeable material that prevents infectious airborne particles from entering the chamber. The system is arranged to receive the machine within the container chamber while controlling passage of infectious airborne particles.
An air-permeable sleeve is provided with a first end and a second end. The first end is engaged to an aperture on the container, and the sleeve surrounds the hosing. The sleeve includes an air-permeable function through its construction from air permeable material, and operates together with the container to manage infectious airborne particle entry relative to the chamber and the hosing connection/opening.
A filter cap is disposed at the second end and covers an opening of the hosing. The filter cap is constructed from the air permeable material, and covers the opening of the hosing at the hosing second end to further control infectious airborne particle entry. In described embodiments, the container may also include a transparent window for operating/visualizing the machine console with a sealable lid over the window, and the system is provided as a single-use unit removed and sterilized after use on each patient.
Claims Coverage
The document provides two independent claims, covering a single-use infection control system with a closable air-permeable chamber container, an air-permeable sleeve engaged to a container aperture and surrounding machine hosing, and an air-permeable filter cap covering a hosing opening.
Closes air-permeable container chamber to prevent infectious airborne particles entering
A closable container having a chamber to receive the machine, the container constructed from air permeable material that prevents infectious airborne particles from entering the chamber.
Engages an air-permeable sleeve to a container aperture surrounding machine hosing
A sleeve having a first end and a second end, the first end engaged to an aperture on the container and the sleeve surrounding the hosing.
Provides an air-permeable filter cap covering a hosing opening
A filter cap constructed from the air permeable material, disposed at the second end and covering an opening of the hosing.
Uses an air-permeable sleeve engaged to a container aperture to cover a hosing opening
A sleeve constructed from the air permeable material and having a first end and a second end, the first end engaged to an aperture on the container, the sleeve surrounding the hosing and the second end covering an opening of the hosing.
Across the independent claims, the core coverage centers on a single-use infection control system that uses an air-permeable, closable container chamber to prevent infectious airborne particles entering, an air-permeable sleeve engaged to a container aperture and surrounding hosing, and an air-permeable filter cap or sleeve second end that covers the hosing opening.
Stated Advantages
Reduced cross-infection by preventing contamination of the internal machine filter/hosing.
Prevention of patient pathogens physically contacting the outside of the machine/hosing.
The unit is sterilized and removed after use on each patient.
Documented Applications
Used for forced air warming machines in an infection control context, as a single-use unit removed and sterilized after use on each patient.
