Definitions

  • the invention relates to a regeneration and hospital bed for the treatment of patients and those in need of relaxation.
  • Hospital beds are known in which the atmosphere surrounding the patient is to be enriched with certain gases, in particular with oxygen. It is also known to maintain a germ-free atmosphere in closed tents or rooms, including incubators for newborns, atmospheres of the desired composition and temperature.
  • the gas mixtures used for this are via supply lines, filtered as required, introduced and drawn off on the opposite side, so that flows with uncontrollable vortex formation arise, which cause partial changes in the gas pressure of the components of the atmosphere and their liquid content, but above all undesirable cooling and drying on the patient's body.
  • the object of the invention is to create a completely calm atmosphere of constant, precisely controllable composition in the environment of the patient or in need of regeneration and to draw off the respected gases and liquid components immediately and without generating noticeable flows.
  • the precisely metered and tempered and air-conditioned gas mixture which is fed into the outer tent area around the actual treatment room is pumped in via a feed line under a more or less strong flow corresponding to the gas conversion and with unavoidable eddy formation.
  • the inner tent made of fine-mesh fabric, which surrounds the patient or in need of regeneration and forms the actual treatment room, only allows diffusion of this gas mixture, so that the fresh gas passes into this treatment room without any noticeable flow and eddies.
  • low-oxygen and moisture-enriched exhaust gas maintains such a large negative pressure in relation to the outer tent space that it causes a smoothly flowing diffusion into the treatment room. This maintains a constant, calm atmosphere with the desired constant content of gas components, moisture and temperature.
  • the entire tent can be separated by a gas-impermeable partition that gently surrounds the patient's neck.
  • the head part can then be supplied with the desired gas mixture.
  • a corresponding inner tent can also be provided there, so that there is also a calm atmosphere in the head part. This is particularly necessary or expedient if medications in gaseous form or as aerosols are to be added to the separated body part, which would be incompatible or disturbing as components of the breathing air.
  • the bed according to the invention can advantageously be used for those in need of regeneration, for example those who have been damaged or exhausted by environmental pollution and who need a sleep or a longer stay in an optimally composed pure breathing air.
  • it is particularly suitable for the treatment of asthma symptoms, altitude sickness, Respiratory tract poisoning, but above all as a bed for burns treatment, whereby the burned areas can be exposed completely open to a correspondingly warm, absolutely moisture-free, absolutely germ-free atmosphere, to which the necessary medicines are added in gaseous form or as an aerosol and with which every heat removal and drying out causing air flow is avoided.
  • the patient can be bedded in any required manner. Another use is the supply of oxygen or of drugs in the gas phase or in aerosols to the patient's skin. Finally, it is possible to maintain a desired air pressure in the inner tent.
  • the regulation and control of the supply of the treatment atmosphere, the metering of its components, its moisture content and its temperature control is carried out electronically in a supply unit, as is the control of the extraction of the used outside air with the necessary time variations, so that a relatively low requirement for the maintenance of the patients given is.
  • the bed shown in Figure 1 has bed posts in the form of slide rods 1, which have balls 2 at their ends.
  • a double tent 3 is vertically displaceable in rings 4 running on the slide rods 1.
  • the double tent 3 consists of a larger outer tent 5 made of flexible, essentially gas-impermeable material and a smaller inner tent 6 made of flexible material which is permeable to gases and surrounded by the outer tent 5.
  • Both tents 5 and 6 have the shape of a hipped roof, which drops in height after the foot of the bed.
  • the outer tent 5 is reinforced on its ridge by a rod 7, on which it is connected to lines 9 with a height-adjustable suspension device 8. In the same way, the lower edges of the outer tent 5 with further rods 10, 11, 12, 13 reinforced.
  • the inner tent 6 is connected at its lower edges to the rods 10 to 13 and thus to the outer tent 5 and is thus stiffened as well. It also has a hipped roof-like shape with a ridge sloping towards the foot end, which is reinforced by a rod 22.
  • the rod 22 is connected to lines 23 and 24 on the rod 7 of the ridge of the outer tent 5 and kept taut.
  • the inner tent 6 is smaller than the outer tent 5.
  • a space 25 thus results between the two, which is sealed off from the outside atmosphere by the gas-impermeable material of the outer tent 5, but is open to gas diffusion from the inner tent.
  • the inner tent 6 is like this great that a patient can lie in it well and sit up.
  • the outer tent 5 has an opening 26 on its base wall into which a flexible further hose 27 opens, which connects the space 25 between the inner and outer tent 6, 5 to a supply unit 28, via which fresh breathing gas into the space 26 with a Overpressure can be pumped from the outside atmosphere.
  • a strip 30 is left free, in which exhaust pipes 31 open at regular intervals, which lead to collecting pipes, not shown, on the underside of the bed, which in turn are connected to a flexible hose 33 with a suction pump Supply unit 28 are connected.
  • the installation of the movable supply unit and the required electronic control circuits are known per se and therefore do not need to be described in more detail.
  • a higher pressure in the gas mixed and already provided by the supply unit 28 in relation to the outside atmosphere and with respect to the interior of the inner tent 6 must be maintained in the room 25. In the inner tent 6 there must still be a certain excess pressure with respect to the outside atmosphere, which prevents outside air from entering through leaks in the lower seal of the outer tent 5.
  • the inner tent 6 consists of a fine-pored fabric that only allows diffusion of the gas from the space 25, but which must consist of an easy-to-clean and disinfect material, for example a fabric made of fine plastic wires with a smooth surface.
  • the material of the outer tent consists at least partially of a transparent film and also that the inner tent 6 has a sufficiently large window, at least on its side facing the head end of the bed, to enable the patient to be observed and, on the other hand, for the patient to avoid psychological stress.
  • the bed shown schematically in FIG. 4 has fixed forehead and foot ends, whereby the foot wall 32 can consist of solid, opaque material, but the front wall 33 is transparent so that the patient can be observed and not left in the dark.
  • the inner tent 34 is divided into a body part 35 and a head part 36. Both parts are clamped onto barrel-shaped frames 37 and 38, the frame 37 for the body part 35 having two intermediate ribs 39. At its highest area is on the inner tent 34 on the foot wall 32 and
  • the rail 40 attached to the front wall 33 projects, on which joints 41 are provided for the front part 42 of the body part 35 that can be opened and joints 42 are provided for the front side 43 of the head part 36 that can be opened separately.
  • an intermediate wall 44 is arranged, which has the same contour and height as the foot and end wall 32, 33. Its circumference is formed by a bow-shaped frame 45, on which a curtain 46 made of gas-tight material all around is attached, which has a vertical slot 47 or a recess from its underside to about half its height and which rests on the mattress, not shown in Figure 4, in sufficient width to form a gas-tight seal. With it, the patient's neck can be enclosed gas-tight and gently.
  • the outer tent 48 is guided up to two thirds of its width in front and rear edges in curtain rails which follow the foot and end walls 32, 33 on the outer edges 49, 50.
  • a round bar 3 covered with soft elastomeric plastic, is arranged on the outer tent, which, when the outer tent 48 is closed, can be snapped into a groove 54 provided on the outside of the bed in order to seal the outer tent 48 here.
  • the inner tent 47 can be divided into two rooms with different gas and moisture contents and temperature by the intermediate wall 44.
  • the body part can be charged with gas compositions and kept below a temperature level that is incompatible with the patient's breathing and head. Different levels of pressure can also be maintained.
  • a second gas supply 55 is provided for the head part in the end wall 33 of the bed, which, like that in the foot wall 32 of the bed, is supplied by the supply unit 28 with the gas, in each case, of a certain mixture, moisture and temperature.
  • the gas is supplied from the supply unit 28 through the pipeline 56, which for the body part, as in the embodiment of FIG. 1, via the hose 27 and the opening 26.
  • a further simplified embodiment of the invention can be a device 60 which, combined with a conventional bed, results in a regeneration bed, for example for use in sanatoriums or hotels.
  • This Device 60 consists of a frame 62 which is formed from two vertical rods 63 and two rods 64 and 65 which are horizontally arranged at a distance of approximately 10 cm above one another and can be pushed over feet 61 provided with rollers 66 on rollers 66.
  • the only diffusion-permeable inner tent 68 which has a hipped roof shape, is suspended from the lower rod 64.
  • the gas-impermeable outer tent 69 is suspended from the upper rod 65, the narrow side walls 70 and 71 of which are essentially vertical, so that the inner tent 68 is surrounded on all sides by sufficient space to the outer tent 69.
  • the fresh air supply 27 leads from the supply unit 28 (FIGS. 1 and 2) into the outer tent 69, which is expediently to be accommodated in an adjoining room, for example the bathroom of the hotel room, in order to switch off disturbing compressor noises.
  • the inner tent 68 is vented via a suction hose 72 leading to the supply unit 28, which has a plastic tube 73 which is closed at the end and has a larger row of lateral suction openings and which is located in the inner tent 68.
  • the inner tent 68 has on its lower edge a circumferential wide strip 74 made of elastic material, which finally wraps around the edge of the bed or mattress.
  • the outer tent 69 is provided with such a strip 75.
  • the front walls 76 and 77 of both tents 68 and 69 are hinged and with their side and bottom Edges connected to the surrounding wall material with circumferential zippers 78, 79 which can be actuated from the inside and outside and are covered from the inside with a sealing strip.
  • These zippers 78 and 79 can be adequately sealed by the fact that the inside of the strips are in contact with them due to the excess pressure in the tents in relation to the outside atmosphere.
  • the elastic edge strips 74 and 75 of the tents 68 and 69 also seal their lower edges sufficiently. The remaining leakages can be compensated for without difficulty by correspondingly increased fresh air supply.
