  • Publication number: 20240066163
    Abstract: Waste processing chamber operates in a loading mode, a processing mode and an unloading mode. In the processing mode, an environment inside the processing chamber disinfects particles of medical waste using ozone. The processing chamber includes an inlet to receive the particles. In the processing mode and unloading mode a hermetic seal is provided between the environment inside and an environment outside of the processing chamber. An outlet extracts the particles from the processing chamber and provides a hermetic seal between the environment inside and the environment outside of the processing chamber. A particle transporting arrangement stirs the particles to move the particles to the outlet for extraction. Sensors measure characteristics of the sealed environment inside the processing chamber. The processing chamber is fluidly coupled to or includes a generator to generate ozone and to maintain a target concentration level of ozone of the environment inside the processing chamber.

  • Patent number: 9579160
    Abstract: The present invention relates to a positioning marker intended to be inserted in tissue. The marker is an elongated object with a longitudinal axis A and with a diameter perpendicular to said longitudinal axis, wherein the diameter is at the most 1.2 mm. The marker further has a predetermined total length LTOT. The marker comprises a plurality of first segments 1 and a plurality of second segments 2, wherein the first and the second segments are arranged alternately after each others. The marker comprises a first material with a density of at least 10 g/cm3, and this material constitute at least 90% by volume of the marker, and a second material that is magnetic and that constitute at the most 10% by volume of the marker.

  • Publication number: 20060288483
    Abstract: Patient repositioning device (10) comprising, a patient supporting panel (20), at least one pair of laterally adjustable side support structures (30a,b, 40a,b) for sideways supporting a patient (50) on the supporting panel (20). To achieve repeatable repositioning of a patient body (50) each pair of side support structures (30a,b, 40a,b) are linked by a link arrangement ensuring that the side support structures (30a, b, 40a, b) automatically are centered about a longitudinal axis (A-A) of the supporting panel (20) indicating the centre of a patient (50) supported on the panel (20). There is also provided a method of repositioning a patient.
