Description

The present invention relates to a method and a device for cleaning,

  disinfect and dry hoses that are part of anesthetic equipment Treatment

  current anesthetic operating equipment is the following

  vant: the anesthetic equipment is stored in a preparation chamber, the chamber is considered hygienically clean A patient is brought there and prepared for the operation so that a mask, connected via a flexible hose to an anesthesia machine, either applied to the patient, which is then brought into the

  operating room where the operation must be performed.

  After the operation, the patient is brought, with the equi-

  anesthetic in place as well as the instruments used

  in a storage room, which is considered to be

  not hygienically clean LS anesthetic equipment

  is removed from the patient and cleaned and disinfected in

  a washing and disinfecting machine Subsequently, the team-

  ment is brought into a drying cabinet to be dried, then leaves the drying cabinet in the storage chamber or in a contiguous preparation chamber, where it

  is stored until it is used by the next patient.

  The instruments used for: the operation are cleaned and disinfected in the storage room, then evacuated

  to be sterilized in an autoclave.

  In the washing and disinfecting machine is provided a special washing support provided with special supports for anesthetic pipes, anesthetic bags or bladders,

  anesthetic masks and for couplings and couplings

  gas pipe fittings The accessories are placed on the washing support which is pushed into the

  wash and disinfect In this is executed a

  after which the support is removed and the elements are placed in a drying cabinet in which are provided special nozzles acting as supports for

  pipes, bags, etc. After drying, rearrange

  additional elements must be carried out Dry elements are placed in special boxes

  or hung in a wardrobe in the preparation room

  tion. The treatment of the anesthetic equipment described above is not entirely satisfactory It is not rational to put the elements one by one on the washing support, to remove the washing support elements and to place in a drying cabinet for, from there, transfer them later to their storage This implies wear of the elements and, the more the treatment is carried out

  hand, the higher the risk of failure from a hygienic point of view-

  nique augmentationo The nozzles of the washing support are intended for the pipes and for spraying hot water and steam into the pipes, and have a conical shape in order to be held in place during treatment The shape of the nozzles causes stretching of the which leads to the risk of medical gases leaking during the administration of narcosis. The disadvantages mentioned above can

  be overcome by the present inventioni For this purpose, the pre-

  sente invention relates to a method for cleaning, disinfecting

  boring and drying pipes that are part of an anes-

  thesicharacterized in that several pipes are placed on nozzles of a cassette, in that a washing support on which the cassette fitted with the pipes is placed, is inserted in a washing and disinfecting machine, in which the pipes are cleaned and that the cassette

  fitted with hoses is taken out of the washing and

  disinfect and place in a drying cabinet-and

  dried, and in that the cassette fitted with the pipes is

  from the drying cabinet to a storage or

  storage placement while waiting for the next use of the pipes. The invention also relates to a device for

  the implementation of the method according to claim 1, charac-

  terized in that it comprises a washing support intended for

  a washing and disinfecting machine, which support the

  vage has a support for a cassette, which support has means for providing a processing medium

  in the pipes placed on the nozzles of the cassette, the

  positive further comprising a support for the cassette, the pipes being placed on the latter, which support is intended

  a drying cabinet and a storage space.

  The invention is described in more detail below with reference to the accompanying drawings, in which:

  the preparation chamber 12 and hang there on a hook

  chet 27 with supports for cassettes.

  The washing and disinfecting machine 22 according to FIG 2 has a door 28 open to a treatment chamber According to the invention, a shaped washing support

  special is used, which will be described below.

  The washing support is slidably mounted on rails 29 located at the lower corners of the chamber.

  treatment and can be connected to conduits for supply

  mentation as a means of treatment The washing and disinfecting machine comprises, in the treatment chamber, rotary arms with jets located at the upper wall and at the bottom, below a grid 30 The machine comprises a control panel provided with a start button 31 and a slot 32 for programmed cards, thanks to which one can choose different treatments in the washing and disinfecting machine Above the start button are provided lamps 33 of different colors which indicate

  among other things that the treatment is in progress and that the treatment

is finished.

  The drying cabinet 24 shown in Fig 4

  presents in its right part baskets 34.35 containing

  for example, operating instruments and masks.

  In the left part of the cabinet are suspended two cassettes 36 with flexible pipes 37 and a cassette 38

with pocket 39.

  As shown in Fig 5, a cassette 36 is hung

  chée at the upper wall 40 of the drying cabinet 24 Under the upper wall 40 are arranged two rails 41,42 They have a shape such that on each side a slide is formed in which the edges can be pushed

  43 of a cassette 36 The cassette 36 has a certain name

  bre of nozzles 45 over which the anesthetic pipes can be slid 37 The cassette 36 also has a metal edge or frame 47 provided with a support 48 for flexible pipes which has recesses 49 intended to keep the pipes 37 in place on the nozzles 45 In addition, the

  cassette has a loop 50 for supporting the pipes.

  In the drying cabinet, the pipes 37 can be subjected to an internal current of hot drying air, indicated by

arrows 44.

  In Fig 6 and 7 is shown one end of a cassette 36 for pipes 37 Y N can observe the edges

  43 and the flat bottom of the cassette and the nozzles 45.1 are above

  pipe holding ports 48 and the support loop 50 Fig 7 clearly shows how a pipe 37 is placed

on a nozzle 45.

  In Fig 8 is shown a cassette for po-

  anesthetic pads 39, which can be inserted by means of re-

  edges 43 in the same way as the cassette 36 for pipes 37, but the cassette 38 instead has long tubes

  thin 51 which are bent in a U shape and which are or

  green at their free end The tubes are suitable for

  ches 39, which can be cleaned with a jet of dry air at

  inside the drying cabinet 24.

  In the washing and disinfecting machine 22.1 a treatment chamber, represented in FIGS. 2 and 9, comprises under the grid 30 and above the bottom a rotary arm with jets, not shown, and a similar arm with jets 52 is planned to

  the upper wall In FIG. 2, inside the chamber

  of treatment, on the right side wall is re-

  presented a tubular connection 53 with a mouth 54 facing forward. In FIGS. 9 and 10, a washing support 55 is shown inside and outside the chamber. This support 55 comprises, among other things, a pair of rails. parallel 56 provided with, wheels 57 intended to roll on the

  rails 29 located in the chamber The washing support 55 includes

  carries a lower frame 58 consisting of a tube provided with an upright 59, which supports on one side of the frame 58 a horizontal support 60 for one or more cassettes 36 or 38 A

  tube 61 extends downward from support 60 and is re-

  curved inward I 1 has an orifice 62 directed

  towards the interior wall of the room.

  As best shown in Fig 11, the support 60 has the shape of a closed square tube. This tube is connected to the frame 58 via the upright 59, as well as to the

tube 61.

  When the washing support 55 is inserted into

  the chamber, the orifice 62 of the tube 61 is inserted in the mouthpiece

  chure 54 of tubular connection 53, after which the middle of

  work can be blown through the nozzles 45 of the cas-
