- the processing machine 1 further comprises a second treatment system capable of treating the external parts of the medical device 2.
- the external parts are treated by immersion, which means that the tank 3 is filled with the chemicals used successively during the treatment.
- the tank 3 is filled with the chemicals used successively during the treatment.
- the volume of the tank 3 necessary to house the medical device 2 important in relation to the volume actually occupied by said medical device 2, such an embodiment leads to a significant and harmful consumption of chemicals.
- the second treatment system operates according to a sprinkling principle.
- the immersion of the medical device 2 in a very large volume of chemical is mainly replaced by a spray by the same chemical, thus using a much smaller amount of said chemical.
- the spray allows to add to the chemical effect of the treatment product a mechanical effect that improves the treatment and thus further reduces the amount of chemical required.
- the second treatment system comprises at least one spray nozzle 6 adapted to receive at least one treatment liquid / chemical under pressure and forcibly projecting said treatment liquid in the volume of the tank 3.
- the spraying thus carried out makes it possible to treat the external parts of the medical device 2. Moreover, it still makes it possible to treat the internal surfaces of the vessel 3.
- Spraying can be carried out using during a whole spraying phase with the same product of permanent treatment of the clean product. This guarantees the best quality of treatment.
- the treatment product can be collected, for example at the bottom of the tank 3 where it flows after being sprayed, for reuse, via said at least one spray nozzle 6 to be sprinkled again during the same phase.
- an immersion, at least partial may be used in addition to the spray.
- This immersion, advantageously partial makes it possible to improve the treatment of the lower part of the tank 3, difficult to attain directly by sprinkling by means of said at least one spray nozzle 6.
- the immersion is understood as the immersion of the medical device 2 in a volume of chemical up to the height of the base 7 of the spray nozzle 6.
- the immersion is carried out by means of at least one filling means comprising for example at least one orifice placed at the bottom of the tank 3.
- the filling means may be said at least one spray nozzle 6.
- the immersion may be carried out before, during or after spraying.
- the two steps sharing the same tank 3 must be performed with the same type of treatment liquid, if they overlap temporally at least partially.
- the treatment of the internal parts of the medical device 2 it is completely independent. It can therefore be performed before, during or after the steps of spraying and / or immersion.
- the treatment of the internal parts of the medical device 2 is made completely leakproof.
- the sealing makes it possible to use different types of treatment liquid at the same time for the internal parts and the external parts of the medical device 2.
- the treatment of the internal parts of the medical device 2 is not made in a sealed manner, the treatment product used then flowing to the bottom of the tank 3. Said treatment product used can be then collected and reused for example via said at least one spray nozzle 6 to be sprinkled.
- the spraying and the immersion are advantageously carried out with clean treatment product.
- the spray can reuse the treatment product used by the immersion, before or during sprinkle.
- the treatment product used, before or during, by sprinkling can reuse for immersion, the treatment product used, before or during, by sprinkling.
- a particularly effective configuration in terms of treatment efficiency with respect to the chemical consumption has appeared to be a substantially elliptical shaped vessel, the second treatment system comprising two spray nozzles 6 substantially disposed at the foci of said ellipse.
- the spray nozzles 6 to effectively disperse the chemicals in the entire volume of the tank 3, while keeping a distance between the spray nozzle 6 and medical device 2 reduced, to ensure the mechanical cleaning effect.
- Such an arrangement makes it possible to place the medical device 2 at 0 or 8 around the two spray nozzles 6.
- a spray nozzle 6 comprises a base 7 for fixing the spray nozzle 6 on the floor of the tank 3.
- This base 7 still allows a fluid connection from the spray nozzle 6 to a pressurized treatment liquid dispensing device.
- the treatment liquid thus received by the base 7 of the spray nozzle 6 passes through a substantially cylindrical central pipe 10 arranged along the axis of the spray nozzle 6. It allows the supply of said cleaning liquid up to a diffuser 8 which extends said base 7.
- the diffuser 8 allows the projection of said treatment liquid throughout the volume of the vessel 3 and on the outer parts of the medical device 2.
- the base 7 comprises a removable fixing means 12 allowing its fixed mounting on the floor of the tank 3.
- the base 7, as well as the nozzle 6, in their entirety, are kept motionless during operation in cleaning the treatment machine 1.
- the same fastening means 12 allows the sprinkler nozzle 6 to be dismantled, for example to allow it to be cleaned or, if necessary, its replacement.
- This fastening means 12 comprises, for example, a screw device or bayonet, advantageously quarter turn, to allow secure attachment and mounting / dismounting quickly and advantageously without tools.

- the cylindrical surface is advantageously pierced with a plurality of holes 9.
- Each of said holes 9 connects the axial pipe
- the central duct 10 is connected to a pressurized process liquid distribution device through which the treatment liquid arrives.
- the appropriate treatment liquid pressure combined with the holes 9 makes it possible to create a projection of said treatment liquid in all directions targeted by said holes 9.
- the axes of the holes 9 are radial and perpendicular to the axis of the diffuser 8.
- a suitable treatment liquid pressure a function of the total accumulated surface of the holes 9 and orifices 11, makes it possible to obtain jets of treatment liquid having a force capable of achieving a mechanical cleaning effect according to a desired force.
- Said pressure may advantageously be determined empirically.
- Another embodiment for obtaining a radially omnidirectional diffusion is a use of a spray nozzle 6 / a rotating diffuser 8.
- Such a rotation can be obtained by a motorization or by the effect of the circulation of the treatment liquid under pressure.
- a diffuser 8 immobile relative to the vessel 3 and thus immobile relative to the medical device 2 during operation of the processing machine 1. This is achieved by a spray nozzle 6 where the diffuser 8 is stationary relative to the base 7, the base 7 being stationary relative to the tank 3, so that the holes 9 remain stationary relative to the tank 3.
- the omnidirectional spray is then obtained by a plurality of regularly distributed holes .
- the holes 9 have a diameter of 1 mm.
- the holes 9 are 140 in number, regularly distributed over a cylindrical diffuser surface 8 with an outer diameter of 18 mm and a height of 45 mm. Either a hole density of 140 holes for an area of about 25.5 cm 2 , or substantially 5.5 holes / cm 2 .
- the distal end of the diffuser 8 is pierced with an orifice 11.
- Said orifice 11 connects the axial pipe 10 to the outside of the diffuser 8 of the spray nozzle 6. spraying of the ceiling of the tank 3. This achieves effective treatment of said ceiling and completes the sprinkling performed by the holes 9.
- the spray nozzle 6 must withstand the corrosion and chemical attack of the chemicals used as treatment liquids. In addition, it must maintain the high pressure that can be used for the treatment liquid. In order to clean, the disassembled spraying nozzle 6 can advantageously be cleaned / disinfected by high temperature steaming. To support all these constraints, the spray nozzle 6 is advantageously made of stainless steel, for example 316L type.
