Description
The present invention relates to a method and to an arrangement for cLeaning, disinfection and drying of hoses comprised in an anesthetic equiprnent. The previous handling of anesthetic equipment at an operation is as foLlows:
The anesthetic equipment is stored in a sterile preparation room. A patient is brought in and prepared or operation whereby a mask, connected through a hose to an anesthetic appacatus, is applied on the patient, who then is rnoved into an operating room, where the operation is to be carried out.
After the operation, the patient is moved with the anesthetic equipment in place together with used instruments to a clean up room, which is not sterile. The anesthetlc equipment is then removed from the patient and cleaned and disinfected in a washer-disin~ector. After that, the equipment is moved to a drying cabinet for drying, and is then taken out of the drying cabinet in the clean up room or in an adjolnlng preparatlon room, where it is stored while awaiting to be used by the next patient. The instrulnents used at the operation are cleaned and dislnfected in the clean up room and are then ~noved to a location to be sterilized in an autoclave.
In the washer-disinfector there is a special washing stand with special holders for anesthetic hoses, anesthetic bladders, anesthetic maslcs and for connections and couplings or gas conduits. These items are placed in the washing stand which is pushed into the washer-disinfector. There a trea-tment is carried out after which the stand is taken out and the items are put into a drying cabinet, where there are special nozzles serving as hoLders for the hoses, bladders and other items.
After drying, a further re-arrangement of the items must be carried out. The dry items are then put into special boxes or hung up in a cabinet in the preparation room.
3.Z2~3968 The handling of anesthetic equipment described above is not entirely satisfactory. It is not rational to put the items piece by piece on the washing stand, remove these from the washing stand and place them in a drying cabinet and therefrom transfer them to storage. This implies wear of the items, and contamination. The nozzles of the washing stand are intended for the hoses and for spraying of hot water and steam into the hoses, and they have a conical shape to ensure that the hoses are kept in place during the treatment. The shape of the nozzles causes the hoses to be stretched, which brings with it the risk of leakage during the administration of anesthetics.
The present invention seeks to avoid these disadvantages. According to one aspect of this invention there is provided a method oE cleaning, disinEecting and drying items of anesthetic equipment comprising the steps of:
i) placing the items on a cassette having a nozzle for the application of Eluid to the interior of the items;
ii) mounting the cassette carrying the items on a washing stand having a holder for the cassette and provided with a conduit for supplying treatment medium to the nozzles of the cassette;
iii) inserting the washing stand into a cleaner disinfector and cleaning and disinfecting the items;
iv) transferring the cassette with the items to a drying cabinet and drying them;
v) transferring the cassette with the items from the drying cabinet to a sterile store.
