Definitions

  • the invention relates to a method for cleaning at least one breathing device, the breathing device comprising at least one breathing mask.
  • the invention further relates to a device for cleaning at least one breathing device, a pre-cleaning device for pre-cleaning personal protective equipment and a cleaning system for cleaning personal protective equipment, in particular at least one breathing device with at least one breathing mask.
  • Such devices and methods can be used in general to clean breathing devices or components thereof, for example breathing devices for rescue workers such as fire departments, technical aid organizations or paramedics, breathing devices for divers or generally people in hostile or critical work environments, as well as for armed forces and security forces such as police officers.
  • the proposed devices and methods can also be used for breathing devices in the medical field, for example breathing masks for oxygen supply and operations.
  • the cleaning of breathing masks or regulators is a general area of application.
  • Breathing devices such as respiratory masks or regulators are usually part of the personal protective equipment of rescue workers, armed forces or security forces, for example.
  • a large number of breathing devices for different purposes are known from the prior art.
  • rescue workers such as fire departments use respiratory masks with filters to remove harmful components from the sucked-in breathing air.
  • a so-called regulator is used, through which the user can be ventilated with a breathing gas, for example compressed air.
  • Regulators which are often also referred to as breathing regulators, generally allow a user to breathe from a compressed gas cylinder or other compressed gas connection and in this way, for example, to stay under water or in another non-breathable or toxic atmosphere.
  • the compressed gas is used, for example compressed air, from the compressed gas connection through the regulator adjusted to a pressure prevailing in the user's working environment.
  • the respiratory devices or their components must generally be cleaned, hygienised, dried, checked and, if necessary, repaired and packaged after each use. Cleaning is intended to remove all contamination resulting from use or storage so that the breathing apparatus can be macroscopically clean and hygienically provided, for example for the next steps in reprocessing.
  • the same requirements generally also apply to other components of breathing apparatus, such as attachments and accessories for breathing masks, such as filters or regulators. Since breathing apparatus and their components are generally safety-relevant devices, several requirements must be observed when cleaning these devices. In addition to adequate cleaning and hygiene, in many cases it should be noted that accessories must remain assigned to the respective breathing masks for technical reasons. Furthermore, there is generally a requirement that gas-carrying areas of certain elements of breathing apparatus, for example gas-carrying areas of regulators, must not come into contact with cleaning fluid, for example water and/or cleaning solution.
  • respiratory devices such as respiratory masks and their accessories
  • a washing machine which has a tub with a drum.
  • a shell of the drum has a curvature structure directed towards the inside of the drum, with holes being arranged in its corner points on edge contours of the curvature directed towards the outside of the drum.
  • a holding system for respiratory masks in a laundry treatment machine is known.
  • the holding system has a support bracket which is arranged to rotate in a drum of the laundry treatment machine and to which the respiratory masks can be connected.
  • Clothes hangers are used, which include flexible air outlet nozzles.
  • the clothes hangers are each on a swivel device attached. Cleaning breathing apparatus is generally not possible or only possible with difficulty using the devices shown.
  • a device for cleaning respiratory masks comprises a lockable housing and at least one receptacle for at least one respiratory mask arranged in a carrier. Furthermore, a nozzle arrangement and a brush arrangement are provided, whereby a movement of the respiratory masks causes the respiratory masks to be brushed.
  • individual assignment and cleaning of mask accessories is not possible.
  • the cleaning of gas-carrying elements, such as regulators is not possible with the disclosed device.
  • DE 200 03 744 U1 a device for cleaning, disinfecting and drying respiratory masks is known, which has a support frame with an assigned nozzle system and individual treatment stations. This device is also fundamentally not suitable for cleaning gas-carrying elements and accessories.
  • a cleaning device for compressed air breathing apparatus is known. This has a receiving space limited by a protective grille and rotating nozzle holders. The nozzle holders are located outside the protective grille.
  • the disadvantage of the device shown is that cleaning liquid can penetrate into gas-conducting areas.
  • a receptacle for equipping respiratory masks is provided, in which the respirators are coupled to the receptacle using the breathing apparatus connection. It is further described that a collection device for collecting treatment agents is provided in a cabin of the device, as well as a pump for supplying the treatment agents.
  • US 3,881,503 A discloses an apparatus for washing and decontaminating anesthesia equipment.
  • a nozzle system is provided through which jets of water can be sprayed onto the items to be cleaned under high pressure.
  • a device for cleaning respiratory masks is described.

  • the respiratory masks are moved with a rotating movement through a bath of cleaning liquid in a tub.
  • WO 2011/144518 A2 describes a cleaning device for cleaning breathing apparatus.
  • the cleaning device comprises at least one cleaning chamber for accommodating at least one breathing device and at least one fluid device for applying at least one cleaning fluid to the breathing device.
  • the cleaning device further has at least one pressurization device with at least one pressure connection.
  • the pressure connection can be connected to at least one gas-carrying element of the breathing apparatus.
  • the pressurization device is set up to pressurize the gas-carrying element with compressed gas.
  • DE 944 416 C describes a device for cleaning filter respirators in which air is forced through the filter device.
  • a range for cleaning breathing apparatus comprising at least two holders, the holders comprising: a first Holder for cleaning breathing masks and regulators, comprising at least one mask holding device for positioning at least one breathing mask, further comprising at least one regulator holding device for positioning at least one regulator and at least one pressurization device with at least one pressure connection, the pressure connection being connectable to the regulator and wherein the pressurization device is set up to pressurize the regulator with compressed gas during cleaning; and at least one second holder for cleaning support frames for compressed gas cylinders for breathing apparatus, comprising at least one support frame holding device for positioning at least one support frame.
  • the holders are dimensioned in such a way that they can be inserted interchangeably into a cleaning device for cleaning the breathing apparatus.
  • PPE personal protective equipment
  • One difficulty is that the transfer of pollutants from the outside of the breathing masks to the inside should be avoided. Cleaning can be carried out manually, for example, by rinsing to remove coarse dirt, especially on the outside of the individual parts such as the breathing masks. However, this process is comparatively difficult to automate. There is also a considerable risk that washing lye, for example, could carry combustion residues such as soot, which can contain substances that are hazardous to health, onto the inside of the breathing mask. Further There is also the risk of dangerous and undesirable substances being carried over from the pre-cleaning step into the final or main cleaning step.
