Abstract

For oxygen enrichment of the blood during sleep the invention proposes that oxygen-enriched air be fed into the space between the cover and the top side of the mattress of a bed. This is done in part through the interior of the mattress with an air-permeable cover layer, in part through a soft interposed mat laid over the sleeper.

Description

The invention relates to a treatment device for Providing a person with additional oxygen according to the preamble of claim 1.

Such a treatment device can be found in EP 0 534 326 A2 be removed. It has one with an oxygen source connectable flexible pipe grille, which with side Delivery openings is provided. The pipe system is surrounded by a cover-like shell. The oxygen source is a chemical reactor.

Other known oxygen treatment facilities usually include as a source of treatment gas a pressurized bottle filled with oxygen that Reducing valve is connected to a hose, the free end wearing a face mask. In this way you can deliver the Ensure oxygen to the user. In particular for long-term therapy, the acceptance is low, since wearing a face mask in treatment sessions is uncomfortable and spend a lot of time on the treatment that cannot be used otherwise.

In contrast, it has now been recognized that oxygen enrichment in human blood also through skin breathing can accomplish. It was also recognized that between the top of the mattress of a bed and the a blanket lying right over a sleeping person well sealed room that has over the only thin nightwear in good flow Connected to the skin of the sleeper. Through the treatment device according to the invention this one large part of the skin surrounding space a corresponding control device with oxygen or supplied with oxygen-enriched air.

Supplying additional oxygen to the circuit about skin breathing is less intense than that Supply via the breathing air, but this can largely compensated for by a considerably longer duration of treatment become. Also is the addition of additional oxygen for the user with no inconvenience and additional time involved; it takes place during of sleep. The one from between the blanket and mattress surface lying treatment room emerging additional Oxygen also ensures oxygen enrichment in the immediate vicinity of the sleeper, so that an additional oxygenation of the blood by breathing in unused oxygen in the treatment room he follows.

The object of the invention is a treatment device Specify the type mentioned at the beginning, the undisturbed Comfortable sleeping and a widespread introduction of the Treatment gas guaranteed in the treatment room.

This object is achieved by a treatment facility with the features specified in claim 1.

According to claim 1 can be simple and for User-friendly way an open-pored interior structure of the entrance mat.

Is used to introduce the treatment gas into the Treatment room an introductory mat that over the sleeping Person lies, then the oxygen escaping from them reaches prefers the respective upper skin areas. You can use it to treat the areas of skin below in principle use a similar mat. this one but is burdened with the weight of the sleeping person, their porous inner structure must be a little harder be, but usually not as a loss of comfort is felt because the surface of a mattress in general is already harder than the one lying over the sleeping person Blanket.

Advantageous developments of the invention are in the subclaims specified.

In Figure 1, 10 is a slatted frame of a bed, the one with battens 12 designated a total of 14 modified spring mattress.

The innerspring mattress 14 has a harder foam manufactured circular frame 16 and two Cover layers 18, 20, which consist of fiber mats. Springs 22 are located between the two cover layers 18, 20 arranged, which are each sewn into a pocket 24. The entire arrangement described above is in one reference 26 sewn in. In this respect, the structure of the innerspring mattress corresponds 14 the classic structure, but it is understands that the two cover layers 18, 20 in detail can be designed differently (summer or winter side).

In the foot area of the spring mattress 14 is now in the Top and bottom each additional and close to Edge attached a connector part 28 which with a on one of the slats 12 attached connector part 30 works together and so the inside of the innerspring mattress 14 connects to a feed line 32, via which of a supply device shown in more detail in Figure 3 supplied with oxygen-enriched air, which fragrances and / or active ingredients may also be added.

To escape this treatment air through each Preventing the bottom layer is between the bottom of the innerspring mattress 14 and the top the slats 12 inserted a barrier film 34, one of the spring mattress 14 is a separate bed part and at Remove the innerspring mattress 14 on the slatted base 10 remains. For this purpose, the barrier film 34 can e.g. by self-adhesive areas on their underside with the tops the slats 12 may be connected.

If the frame 16 of the spring mattress 14 is not already essentially impermeable to air, so it is its inside covered by another barrier film 36. This can also with edge sections 38, 40 over those edge areas of the air-permeable Cover layers 18, 20 extend on which normally a user is not lying. The edge portions 38, 40 are thus wide in the lying area of the legs, narrow in the area of the back and wide again in the head area. In supervision can see the contour of the free edges of the edge sections 38, 40 e.g. at a distance of about 20-30 cm the edge contour of one lying in the middle of the bed Follow user.

A sheet 42 is shown above the spring mattress 14, which in the usual way between the mattress and the slatted frame 10 is clamped.

A pillow is shown schematically above the innerspring mattress 14 44 and a duvet 46 reproduced.

In the space between the duvet 46 and the The top of the innerspring mattress 14 is a total reproduced with 48 marked Einleitmatte. This has a soft loose and loose filling 50 which e.g. by a mat can be formed from wool fibers. alternative can the filling 50 by a two-dimensional ball chain be formed from polystyrene balls or the like, with the individual balls passing through them are held in a flat, mesh-like geometry, as explained in more detail later with reference to FIG. 5 becomes.

The filling 50 is of a permeable coating 52 surround. The latter carries a connecting piece 54, the via a connecting hose 56 to the feed line 32 is connected.

The insertion mat 48 has a lengthwise and a lateral direction Slightly smaller dimension than the feather bed 46, so that hanging over them edge portions of the feather bed 46 also cover the mat 48 and seal against the environment when someone is sleeping in bed Person between the top of the innerspring mattress 14 and the underside of the inlet mat 48 is located. Will the Feed line 32 while the user is asleep pressurized oxygen-rich air, it arrives over the permeable top of the innerspring mattress 14 and the permeable sheet 42 and also permeable user's nightwear to the ones below Skin. In a similar way, it comes from the introductory mat 48 released oxygen-enriched air the upper skin areas.

In a modification of the embodiment of Figure 1 can a blanket and the mat 48 also together fasten. You can also put this in a common coating stuck.

If the user does not want a duvet, e.g. in summer, you can use a mat with a cover that no air passes on the top and thus the otherwise the sealing function, which is taken care of by the duvet.

The oxygen supply to the feed line 32 can in principle via an oxygen bottle that is exchanged at intervals and a reducing valve. Figure 3 shows an oxygen supply device in which the Oxygen is generated locally.

A compressor 58 acts on an oxygen enrichment unit 60 with compressed air. The latter includes e.g. a membrane, the different permeability to oxygen and Contains nitrogen. The oxygenation unit 60 thus splits the compressed air supplied into two partial flows on, one of which is a nitrogen-rich partial stream is delivered via a line 62, which is preferably is led outside through the building wall. The oxygen-rich Partial flow is via a line 64 and a 3/3 control valve 66 pressed into a storage bottle 68, moving control valve 66 into the corresponding one Working position by a compressor 58 assigned Control unit 70 simultaneously with the switching on of the Compressor 58 is made.

The control unit 70 is for this purpose with the electrical Output signal of a pressure sensor 72 applied, the in connection with the interior of the storage bottle 68 stands and generates an output signal when the Pressure in the same dropped below a predetermined value is. The control unit receives a second input signal 70 from a timer 74 on which the user sees those Compressor working hours at which he can by any work of the compressor 58 is bothered. The control unit 70 processes the two input signals essentially in AND operation.

In a second of the control valve 66, the manual is adjustable, the interior of the storage bottle 68 with a line 76 and a pressure reducer 78 with a mixing bottle 80 connected. This contains a volume of liquid 82, which contains fragrance and / or active ingredient. By bubbling through the oxygen-enriched air the liquid volume 82 will be the oxygen-enriched Air or fragrances and / or active ingredients added. The treatment air thus obtained is passed manually actuated cocks 84 fed to the feed line 32.

A heating unit 85 is shown schematically behind the tap 84 reproduced which is the oxygen-enriched air to a temperature close to that of the skin Warming up temperature set by the user can.

As can be seen from Figure 2, the connector part 28 a sleeve section 86, which is a flange section 88 wears. The part under the flange portion 88 the sleeve portion 86 is through an opening 90 performed, which are provided in the cover layer 20 and the cover 26 is. On the lower end face of the sleeve section 86, a cover 92 is glued, whereby an essentially fluid-tight implementation of the connector part 28 through the cover layer 20 and receives the reference 26.

The upper end of the sleeve section 86 is normal connected by a pivotable valve flap 94 which biased into the closed position by a wire clip spring 96 is.

The connector part 30 carries a stop flange 98, the location of which is chosen so that in its installation an upper end portion 100 of the Connector part 30 over the upper end of the sleeve portion 86 protrudes, forcing the valve flap 94 opened against the force of the wire clip spring 96 becomes. To prevent the oxygen-enriched Air inside the innerspring mattress 14 to facilitate, are 100 edge recesses in the end section 102 is provided.

Figure 4 shows a modified bed in which one normal mattress is used, its internal structure not interested here.

A lower insert mat 104 is provided above the mattress 14, which in turn is an open-pored filling 106 and a cover 108 made of permeable fabric having. The filling 106 is now made of harder Open-pored foam material made, the hardness essentially that of harder foam mattress cores can correspond. In the filling 106 are transversal Direction and longitudinal direction Channels 110 provided with a main distribution channel 112 communicating from a connector 114 is fed here. The latter is over one again Connection hose 116 connected to the feed line 32.

The lower lead-in mat 104 is between the top the mattress 14 and the sheet 42 arranged. To this The lower lead-in mat 104 provides the oxygen supply to the underlying skin sections one in bed lying person, similar to this in the embodiment 1 accomplished the modified innerspring mattress 14.

Figure 5 shows a section of a modified compliant filler that can be used for the introductory mat 48 is.

Made from styrofoam or another lightweight plastic Balls 118 have three mutually perpendicular bores 120, 122, 124. By lying in the mat plane Bores 120 and 122 are transverse holding threads 126 and longitudinal holding threads 128 pulled through. As can be seen is the diameter of the bores 120, 122 and 124 significantly larger than the diameter of the holding threads, so that these channels also act as a passage for treatment air serve. Further passes through which a distribution the treatment air over the inlet mat 48 takes place, exist between the outer surfaces of the balls 118 and the cover 52, the sides of which are covered by the ball mat are spaced.

Alternatively, you can build a ball mat out of fiber balls, through which the holding threads are pulled with a needle are.

Figure 6 shows the generation of oxygen enriched Air for a variety of applications, e.g. beds of a hotel or clinic.

In principle, the treatment gas is generated in a similar way as shown in Figure 3.

The outlet of the mixing bottle 80 is now with the entrance another compressor 130 connected. The compressor 130 also sucks via an adjustable throttle 132 ambient air on. The setting of throttle 132 takes place in such a way that the total oxygen content of the mixture is around 38%. This is with regard to fire protection advantageous. The output of the compressor 130 is via a valve 134 with a storage bottle 136 connected, which in turn carries a valve 138.

Preferably, the volume of liquid 82 contains one of the active ingredients sea salt, and generating the aerosol from Oxygen-enriched air and liquid are preferred with simultaneous exposure to UV light, which is generated by a UV lamp 140, which in the mixing bottle is arranged (or in a quartz window or other UV-permeable window Blending bottle blows).

After filling storage bottles 136, these can then each connected to a bed in the building, in the simplest case only to the inlet mat 48, if also requested on the modified innerspring mattress 14. By setting a pressure reducer 142 can set the amount of treatment gas supplied become.

The volume of the storage bottle 136 is dimensioned such that the amount of treatment gas contained in it for one Night is enough. In practice, 5-liter storage bottles are sufficient that are easy to handle. After the storage bottle 136 is exhausted, it becomes routine changed when the room was made and e.g. also the towels are changed.

The type of supply shown in Figure 6 for a variety of application sites with treatment gas can be without Install changes to buildings easily and inexpensively. The part shown on the left in FIG. 6 for generating and Compressing the treatment gas can be pre-installed Block installed in a technical room of the building become. It essentially only needs one electrical outlet. The lead-in mats 48 are inexpensive Parts that are easy to use even in conventional Beds can be attached.

This creates the possibility of an oxygen treatment in an existing bed either at an affordable price To be able to provide costs.
