Definitions

  • the invention relates to a regeneration and hospital bed for the treatment of patients and those in need of relaxation and a method of controlling the atmosphere in a regeneration and hospital bed.
  • Atmosphere surrounding patients with certain gases, in particular to be enriched with oxygen. It is also known to be in closed tents or Rooms, including in incubators for newborns, atmospheres desired composition and temperature, especially to maintain a sterile atmosphere.
  • the gas mixtures used for this are via supply lines, filtered as required, inserted and subtracted on the opposite side, so that currents with uncontrollable vortex formation arise, the partial changes of the Gas pressure of the components of the atmosphere and their Liquid content, but above all undesirable Cooling and dehydration on the patient's body cause.
  • Such hospital beds are especially from the French Patent application FR 2 226 980 known, fresh gas from a storage space is introduced via a filter wall into a tent that surrounds a patient. Here becomes a controlled, completely calm atmosphere with constant Composition in the patient's environment, however, is neither sought nor enables.
  • the invention has for its object in the area of the patient or in need of regeneration completely calmed atmosphere of constant, precisely controllable Creating composition and respected Gases and liquid components immediately and subtract without generating noticeable currents.
  • the directly to the patient or those in need of regeneration surrounding, forming the actual treatment room Inner tent made of fine-mesh fabric leaves only a diffusion this gas mixture too, so that the fresh gas without noticeable current and vortex formation in these Treatment room merges.
  • vacuuming the used up especially low-oxygen and moisture-enriched Exhaust gas becomes such a large negative pressure maintain against the outer tent room, that he has a smoothly flowing diffusion into the treatment room causes. This will make this one always the same calm atmosphere with the desired constant content of gas components, Maintain moisture and temperature.
  • the entire tent can be covered by a gas-impermeable partition that can be separated gently encloses the patient's neck.
  • the Headboard can then do with the desired one Gas mixture can be supplied.
  • There can also be a corresponding inner tent may be provided so that in the headboard also has a calm atmosphere. This is particularly necessary or useful if the severed body part medication in gaseous form or to be supplied as aerosols as components of the breathing air incompatible or disruptive would be.
  • the bed according to the invention can be advantageous for those in need of regeneration, for example through pollution Damaged or exhausted, use find a sleep or a long stay in an optimally composed pure breathing air need.
  • it is particularly suitable for that Correction of asthma symptoms, altitude sickness, Respiratory poisoning, but especially as a bed for the burn treatment, the burn injured Surfaces completely open to a correspondingly warm one absolutely moisture-free, absolutely germ-free Atmosphere can be exposed to the required Medicines in gaseous form or as an aerosol be added and taking away any heat and dehydration causing air flow is avoided.
  • the patient's bedding can be required in any way Way. Another use is the supply of oxygen or in the Gas phase or drugs present in aerosols to the patient's skin. Finally, it is possible maintain a desired air pressure in the inner tent.
  • the bed shown in Fig.1 has bed posts in Form of slide rods 1 on which balls at their ends 2 have.
