Packaging for a medical endoscope

A method for packaging a medical endoscope comprising the following steps:

• a) having a medical endoscope including an operating handle, an insertion tube, and optionally a power cable,
• b) having a tray provided with an inner face having a peripheral area, said tray comprising on its inner face a housing intended to receive a medical endoscope, the housing being composed of a cavity intended to receive the operating handle, a rectilinear groove intended to receive the insertion tube, and optionally a gutter intended to receive the power cable, the groove having a section greater than the section of the insertion tube to allow its free insertion, said tray comprising protuberances projecting from its inner face and arranged on either side of the groove,
• c) having a sheet permeable to gases and beta and gamma radiation, impermeable to microbes and heat-sealable,
• d) placing the medical endoscope in the housing,
• e) contacting the heat-sealable sheet with the peripheral area and with the protuberances, heating to a sealing temperature, applying a peripheral sealing pressure on the peripheral area allowing hermetic sealing of the sheet on the peripheral area to obtain a pull-out force, and applying a central sealing pressure on the protuberances allowing the sheet to be fixed on the protuberances to obtain a pull-out force, the peripheral sealing pressure and the central sealing pressure being such that the pull-out force between the sheet and the protuberances is at least 30% less than the pull-out force between the sheet and the peripheral area.
