Abstract: A plasma source for generating a disinfecting and/or sterilizing gas mixture, including an ionization chamber having a dielectric tubular portion, an inflow port for feeding a gas or gas mixture into the chamber, an outflow port for exhausting the disinfecting and/or sterilizing gas mixture out of the chamber, a first electrode positioned inside the dielectric tubular portion, and a second electrode positioned outside the dielectric tubular portion. The plasma source has a high voltage source having a high voltage output terminal, wherein an electrical conductor connects the output terminal to the first or second electrode, and a forced gas cooling system for cooling the ionization chamber.

Abstract: A device and method for sterilizing one or more medical instruments. The device includes a sterilizing chamber for holding the medical instruments to be sterilized, a pressure reducer for selectively reducing the pressure in the chamber, an atmospheric or superatmospheric plasma source for providing a sterilizing mixture, and a duct for guiding the sterilizing mixture from the plasma source to the sterilizing chamber. The duct includes a choke arranged for causing a choked flow of the sterilizing mixture from the plasma source to the chamber when the chamber is at the reduced pressure for preventing pressure drop in the plasma source.

Abstract: A method and apparatus for sterilizing medical instruments, including a device for controlling specific humidity, SH, of flow of a gas or gas mixture. The device includes a tank for storing a volume of water. The tank has an inflow port for receiving the gas or gas mixture, and an outflow port for allowing humidified gas or gas mixture at the required SH to exit the tank. The temperature of the water and/or the pressure of the supplied gas or gas mixture are controlled for the required SH.

Abstract: A method and apparatus for sterilizing a medical instrument, such as a dental instrument. The method includes placing the medical instrument in a chamber, providing a sterilizing agent including recombined ionized humidified air, controlling the temperature of the medical instrument and/or the chamber such that the temperature of the medical instrument is below the temperature of chamber, and at least partially condensing the sterilizing agent onto the instruments.

Abstract: The disclosure relates to a syringe, comprising a barrel and a plunger, wherein at least a part of said plunger is longitudinally slidably received in the barrel, wherein the plunger comprises a portion that is provided with at least one series of interspaced plunger formations, wherein the barrel is provided with a corresponding barrel formation for consecutively engaging successive ones of the plunger formations, wherein the syringe is arranged such as to be brought from a first state in which the barrel formation successively engages the plunger formations during slidable displacement of the plunger within the barrel, into a second state in which the barrel formation is held in a position spaced away from the plunger portion that comprises the plunger formations.

Abstract: The invention relates to a decontamination device for medical instruments and a method for decontaminating medical instruments. The device includes a reception unit arranged for receiving a to be treated medical instrument. The device further includes a washing unit arranged for washing and/or drying the instrument. The device includes a disinfection unit arranged for disinfecting the instrument. The device includes a delivery unit arranged for presenting the disinfected instrument to be taken out of the decontamination device.

Abstract: A method and system for reprocessing a reusable medical instrument. The method includes providing a container including a tray and a lid, the tray having an opening for inserting therethrough the medical instrument into an inner space of the tray, and the lid being arranged for closing the opening. The method includes inserting the container into a decontamination device, inside the decontamination device decontaminating the tray, the lid and the medical instrument while the lid is positioned away from the opening. The method includes, inside the decontamination device, a container handler of the decontamination device closing the container by closing the lid onto the tray for closing the opening, and removing the closed container containing the decontaminated medical instrument from the decontamination device.

Abstract: The invention relates to a syringe having a longitudinal axis and comprising a barrel assembly including a barrel extending longitudinally between a proximal end and a distal end, and a collar provided at the proximal end of the barrel and defining a reading window. The syringe also comprises a plunger including a longitudinally extending graduation portion that is at least partially longitudinally slidably received in the barrel, and that provides for at least two mutually different visually readable graduations, wherein respective graduations extend along the longitudinal axis and are alternatively selectable by rotation of the graduation portion around the longitudinal axis, such that a selected graduation is visible through the reading window when the plunger is slid into and out of the barrel during use.

Abstract: A heating apparatus (10) for heating materials used in dental treatment is provided. The heating apparatus (10) comprises a heating compartment (33) with a heating element (35) for heating air inside the heating compartment (33), at least one socket for receiving and holding at least a part of the materials used in dental treatment inside the heating compartment (33), and an airflow generator (32, 34) for generating an airflow in the heating compartment (33).
