Definitions

  • the invention relates to a method for the automated processing of a reusable medical device, which is to be used in a germ-free or sterile manner, which has cavities, channels and / or sliding surfaces.
  • the invention further provides an arrangement for carrying out the method.
  • Reusable medical and surgical instruments must be cleaned, disinfected and, if necessary, packaged and sterilized after use. In conventional surgical instruments, this can be done, for example, by cleaning and thermal disinfection in a cleaning and disinfecting device (RDG) with subsequent
  • thermolabile materials such as rubber, plastic or the like
  • the invention has for its object to provide a method and an apparatus of the type mentioned, or which allows a particularly simple, careful and rapid treatment of medical devices.
  • the inventive method comprises the following steps:
  • Reusable medical devices are reusable instruments and / or apparatus that usually fall under the Medical Devices Act.
  • it may be minimally invasive surgical (MIS) instruments, as well as rigid or flexible endoscopes.
  • MIS minimally invasive surgical
  • the medical devices have cavities, channels and / or
  • these terms refer to areas that are not readily accessible by spraying or flushing with external treatment medium.
  • these may be hoses or lumens (eg working channels) of endoscopes or facing sliding surfaces of moving parts such as scissors or the like.
  • the medical device is inserted in a first step in a lockable cassette.
  • Insertion means that it is placed there in a preferably defined position.
  • corresponding holders can be provided in the cassette.
  • the cassette is lockable. It is thus a container in which the medical device is protected after inserting and closing the cassette from environmental influences.
  • the cassette has connections for the supply and removal of reprocessing media. through These connections, the cassette and the medical device located therein are flowed through by the treatment media.
  • the closable cassette has one or more ports to which flushable cavities and / or channels of the medical device are connected. These connections in the interior can be arranged directly on a wall of the cassette, they can also be provided with pieces of pipe or preferably flexible hose ends, so that they can be brought to corresponding terminals of the medical device. Flushable hoses, channels or other lumens, for example, an endoscope are thus according to the invention selectively connected with An-conclusions of the cassette, so that in the course of the treatment process, a defined feeding into and through the channels or cavities can take place.
  • fresh treatment medium is used for each process step.
  • fresh means that the medium has not yet been in contact with a medical product for the purpose of preparation, in particular not being circulated (as in the prior art).
  • the medium gets in the cassette with the medical device and its cavities, channels and / or sliding surfaces in contact and performs the treatment.
  • supply ports of the cassette are designed so that they direct treatment medium specifically in these cavities or channels.
  • the cassette has one or more connections inside, to which cavities or tubes of the endoscope are connected, and as a result of which treatment medium flows through in a targeted manner during the preparation, as described above.
  • the medical device may be rinsed with treatment medium from the outside.
  • the inlet and outlet ports of the cassette have closable valves, so that the medical device contained therein can be hygienically stored germ-tight in the closed cassette. It is preferred if these valves close automatically when the outer inlet and outlet ports are released from the cassette.
  • the treatment medium is removed from the discharge port (s), i. removed from the cassette. It is discarded immediately thereafter, that is to say supplied to no further utilization in the context of the method according to the invention.
  • this is a cleaning in which the one or more treatment media are discarded after a single use.
  • liquid processing media are used, in particular they may be water-based cleaning, disinfecting and / or sterilization solutions. Discarding after a single use in the context of the invention means that there is no intended repeated contact of the same (already used) cleaning solution with the medical device. Thus, no treatment medium is circulated, so that it is completely or partially fed back to the Zuglassan- conclusions of the cassette after the discharge from the discharge ports of the cassette within the same processing steps. Nor is there any recirculation of treatment medium within the cassette or other recycling uses of the treatment medium, such as a and pumping or conveying treatment medium through the cassette or through cavities of the medical device, or the like.
  • the treatment medium is guided in the cassette as well as in the flushable cavities and / or channels substantially unidirectional.
  • cavities such as hoses or lumens are essentially only flowed through in one direction and the medium is collected after exiting the cavity, for example at the bottom of the cassette, and is discharged therefrom directly.
  • a unidirectional flow through the cassette means that the treatment medium entering the interior of the cassette, for example sprayed there, runs along the outer surfaces of the medical device (preferably by the action of gravity) and is likewise collected, for example, at the bottom of the cassette and removed therefrom.
  • the temperature of the treatment medium during the entire Aufleungspro- zesses does not exceed 100 0 C.
  • the method according to the invention can thus be used particularly advantageously for thermo-labile medical products which can not be treated with the steam sterilization customary in the prior art (temperatures above 120 ° C.).
  • the low thermal stress caused by the method according to the invention is advantageously also applicable to those medical products which, although in principle tolerated a higher temperature, but whose lifetime is limited by higher temperatures, such as in steam sterilization.
  • the method according to the invention can also be treated gently and used accordingly more frequently.
  • multiple reprocessing of the endoscopes with reprocessing medium circulated in the circuit is always provided in the automated reprocessing of endoscopes. Behind this is the idea that the processing should be done with the smallest possible amounts of the treatment medium.
  • the invention has recognized that this cycle cleaning is disadvantageous. In particular, it leads to possible local contaminations in the endoscope being transmitted through the circulation to the entire system and thus to the endoscope. So there is a continuous recontamination.
  • the cleaning according to the invention has the effect that the treatment medium absorbs contaminants and these are removed immediately by discarding. Re-contamination can not take place.
  • an effective and rapid treatment can take place despite the significantly lower volumes of treatment media conducted through the endoscope, in contrast to the circulation cleaning.
  • cavities such as tubes of an endoscope in the method according to the invention from the "clean" operator end, which faces the surgeon when using the endoscope, to the "dirty" distal end, which is in use in the operating area, be flowed through.
  • the treatment according to the invention may comprise a cleaning and disinfection.
  • cleaning and disinfection are defined in the draft DIN EN ISO 15883-4 in the version of June 2005.
