dry air is not treated or at least not treated in an optimal way can be.

A device of the type described at the outset is already known in which the outer wall is provided with an opening " through which the water or another liquid is brought into the storage body. The arrangement is so

k made sure that the storage body routs out of the device without further ado is removable. This can be disadvantageous, in particular because it cannot be determined with certainty whether after using the device, the storage body is completely dry is. If there is repeated residual moisture there is then in the storage body there is a risk that there will be odors and other undesirable phenomena. Another disadvantage 'The known device is that during the filling process it is not immediately recognizable how much liquid the storage body has absorbed. So it can happen that.

P the storage body is only imperfectly filled, so that the space through which the moist air can be inhaled is shortened accordingly. On the other hand, the case can also arise that more water is put into the device than that Storage body is able to accommodate, so that under certain circumstances free liquid is present in the device. This is: undesirable in view of the fact that the device is electrically heated.

309824/0568

The invention is thus based on the task, a device of the type described in the introduction in such a way that the storage body is easily accessible, possibly also from the device is removable. In particular, it should be possible, if necessary, to remove the storage body without difficulty to replace.

To solve this problem, the invention proposes that the The part carrying the mask and the storage body from the outer wall and part having the ice element, preferably in the axial direction is removable. The advantage of this configuration is that once the storage body has been removed for the purpose of filling can be, xfor particularly easy handling and there is also a good possibility of checking with regard to the degree of filling.

An embodiment has proven to be particularly useful in which the Iiaske and the outer wall are provided with an intermediate piece are connectable to each other, the one facing the outer wall Side the preferably hollow cylindrical Storage body carries so that this in disassembled State of the device opposite "protrudes from the intermediate piece and easily accessible practically over its entire extent is. Furthermore, the storage body can preferably be detachably attached to the intermediate piece by means of a Γ-aonet catch, so that that if necessary, a new memory "

The outer wall advantageously carries at least one recess, preferably arranged on the inside, on its end region facing the intermediate piece, to which one or more lugs on the intermediate piece or extension are assigned. It is therefore possible, after a relative rotation between the outer wall and the intermediate piece or extension thereof, to pull the storage body carried by the intermediate piece out of the outer wall.

As a rule, the intermediate piece or extension is provided on the side facing the heating element with an annular projection which rests on the sealing ring. Furthermore, it has been found to be advantageous to make an arrangement in which the sealing ring - optionally with the interposition of a spacer ring - also rests on the accumulator body. In addition to its actual effect as a sealing element, the preloaded sealing ring also has the function of keeping the parts, in particular the heating element, storage body and adapter, under a certain preload, which can be used, for example, to keep the bayonet locks under a preload, which unintentional opening of the same is prevented. In addition, certain tolerances in the fit of the individual parts are compensated for by this elastic sealing ring, so that they cannot move in their holders, seats and the like during normal handling of the device.

The embodiment shown in the drawing consists in essentially of one to be placed on the patient's face Mask 20, an intermediate piece 21, which * encloses a chamber, and a part 23 containing a heating element 22, which also serves as a handle. The heating element 22 is connected via a cable 24 a voltage source can be connected. The connection between cables 24 and heating element 22 takes place via a readable plug connection with the plug contacts 25 and the plug 26.

The heating element 22 is tubular. Inside ' a thermostat 27 is arranged. On the outside it has a solid, porous .body, ζ. B. surrounded by a filter stone or the like 28, which serves as a fluid reservoir. ·

The storage body 28 is an inner wall van ₃₁ surrounded, forming with an outer wall 32 and the depending Speicherkürper 28 an annular chamber and 34 respectively. In the lower region of the part 23 there are holes 35 through which the air to be inhaled by the patient first reaches the annular chamber 34 and from there through holes 36 in the inner wall 31 into the annular chamber 33. In the latter, the air flows downwards.

21 into the haske 20 and finally into the patient's respiratory tract, the mask 20 is in front of his face.

During the passage through the annular chambers 33 and 34 and the Inside 40, the air is heated to the desired temperature, which is adjustable by means of the thermostat 27. Simultaneously insulation of the outer wall 32 is achieved, so that inadmissible heating of the same is avoided.

Takes its way through the part 23 as described above the air at the same time moisture from the storage body 28 on.

The storage body is releasably attached to an extension 45 of the intermediate piece 21. Intermediate piece 21 and extension 45 can also be designed in one piece. For reasons of production, however, it is more appropriate to manufacture the extension 45 for yourself and then later z. B. to be connected to the intermediate piece 21 by gluing. The extension 45 is provided at its free end with recesses 47 extending from the edge 46, which initially run in a direction parallel to the longitudinal axis of the part 23 and then each merge into an area 48 running approximately in the circumferential direction. The arrangement is such that the section 49 of the recess facing the free hand 46. 47 represents a complete opening of the wall of the extension 45, but the adjoining Abcclmitt 47 and the area 48 running in the circumferential direction

only through a recess in the inner square surface 650 ■ are formed.

The hollow cylindrical storage body 28 is provided at its end facing the mask with a ring 51, for example made of plastic or other suitable material, which is connected to the storage body 28, for example. B. is connected by gluing. This ring 51 has two radial projections 52 on its outer circumference, which cooperate with the recesses 47, 48 ~ in extension 45 in the manner of a bayonet lock. I. E. that is, to attach the storage body 28 to the intermediate piece 21 or its extension 45, the storage body is initially moved in the direction of the intermediate piece 21, i.e. axially, in such a way that the projections 52 slide into the recesses 47, whereupon, when the projections 52 are at the level of the areas 48, by a rotation of the storage body 28 and thus the ring and the projections 52 carried by it, the latter come to lie in the areas -48 of the recesses 47. The arrangement can be made in the usual way in such a way that the area 48 or at least one (27) of the boundary surfaces thereof runs slightly obliquely, so that the two projections 52 experience a certain fixation that precludes unintentional loosening of the connection. This fixation is supported by a sealing ring 53 made of rubber-elastic material, preferably silicone rubber, which presses against the ring 51 of the storage body 38 and the Iieiz-, element 22 via an intermediate ring 54 and these parts under a certain Vornan-

-nung holds. The extension 45 has an annular projection 30 provided, the middle area of the sealing ring 53 is present.

The outer wall 32 is on the inside with its upper end area two opposing recesses 55, each of which consists of two areas 56 and 57. The upper area 56 is delimited on one side by two inclined surfaces 58 in such a way that it is approximately triangular in side view Has shape, at the apex of this triangle., The becomes narrower in the direction of the lower region 57, a passage 59 is provided, the two areas 56 and 57 together connects. The lower region 57, which is designed as a groove running in the circumferential direction, has a larger radial groove Depth than the upper area & 56 (Figures 6 and 8).

The parts cooperating with these two recesses 55 of the outer wall 32 are two radial lugs 60 located on the extension 45 of the intermediate piece 21 and two outer projections 6I located at the upper end of the inner wall 31. The latter are each carried by a web 62 which protrudes upward beyond the upper boundary 23 of the inner wall 6l.

The upper region 56 of each recess 55 essentially serves the introduction of the associated lug 60 or the associated projection 61 in the groove-shaped lower region 57

309824/0568

During assembly, the procedure is such that the inner wall 31. This insert does not present any difficulties, since the projections are guided by the Schrägflächen.58 necessarily KFC in dx & toward the passage 59 6l. ■ The inner wall 31 is then rotated to a ^ age h, in which the projections 6l ± h in Fig. Take the position shown in the drawing. In the latter, the projections 61 and thus also the inner wall 31 are secured by a small projection 64 attached to the boundary wall of the area 51. This projection, which expediently consists of thermoplastic material, that is to say has a certain elastic resilience, is sufficient, on the one hand, to prevent undesired rotation of the inner wall 31. On the other hand, this small projection is so flexible that when an external force acts on this projection in a circumferential direction, it can be elastically deformed to such an extent that the associated projection of the inner wall 31 can be displaced over the projection 53. ' t

If the two extensions take the position shown in FIGS. 5 and 6 of the drawing, the extension 45 of the intermediate piece 21 also from above into the upper portion of the foreign

wall 32 are introduced. Fog. 5 of the drawing shows that the openings 49 and subsequent recesses 47 on the one hand and the lugs 60 on the other hand so ■ each other Toggle

are arranged so that when the lugs 60 are guided through the respectively associated passage 59 into the lower region 57, the recess 55, the opening 49 at the lower free end of the extension 45 engage from above over the respectively associated web 62 of the inner wall 31, so that in the circumferential direction there is a positive connection between these two webs 62 on the one hand and the two openings 49 on the other hand. The position of the parts in the assembled state is shown in FIG. 7, the storage body 28 not being shown here, as in FIGS. 5, 6 and 8 for reasons of clarity. Around the extension 45 and thus the intermediate piece 21
and to secure the parts assigned to it in that position in
which the extension 45 is located within the upper area of the outer wall 32, a turning movement about the longitudinal axis of the part 23 is transmitted to the extension 45. This rotary movement is indicated by the arrow 65 in FIG. 7. The extent
the rotary movement is denoted by 66 in FIG. 8. At the end of this rotary movement in the direction of arrow 65 take the extension

on the other hand, these webs and thus the inner wall 31 are taken along. In this case, in the manner already described, the

-lodes associated web 62 is not hindered. In Fig. 8 of the drawing For the sake of clarity, the second position of the projection 6l is not shown.

The inner wall 31 is with the-already mentioned insert 39 in "the Way .connected that the former has openings 67, engage in the strip-shaped projections 68, which on the outer circumference. catch of the insert 31 are attached. Here, too, it can be assumed, that both parts, that is to say the inner wall 31 and the insert 39, consist of a preferably thermoplastic material, which has some elastic deformability, making it possible is to guide the inner wall 31 during assembly with its lower end over the insert 39 until the strips 68 into the openings 67 intervene. The heating element 22 is also carried by the insert 39 with a sealing ring 68 in between, the heating element 22 is fastened by means of clips 69, one end of which engages in the openings 37.

Due to the above-described connection between inner wall 31 and insert 39, the latter, including a holder 70 for the plug contacts 25, take part in this rotary movement. The insertable into the plug ¹ parts of these plug contacts "protrude into 'a recess 71 at the bottom 72. The latter is connected to Jer üii ,. · senwand 32 in.

Usually take the parts, especially inner wall 31 and .Aussenwand 32, the one shown in Figures 1, 2, 4 and 10 Position to each other. In order to introduce the liquid into the storage body 28, the latter must be removed from the part 233. to For this purpose, the intermediate piece 21 with extension 45 around the Hass 66 (Fig. 1 and 3) in the direction of arrow 73 relatively opposite the outer wall 32 rotated, which for reasons of manufacture ■ or to achieve a special appearance from two parts 32a and 32b can exist. Now, at the end of this turning movement, take the parts to each other in the position shown in Figures 5-8 a. It can be assumed that the inner wall 31 is due to the presence of the webs 62 and the openings 49 positive connection has participated in this rotary movement. This also applies to the plug contacts 25 at the lower end of the part 13, as the holder 70 for these plug contacts over the insert 39 has taken on the rotational movement of the inner wall 31.

The above-described rotational movement of the intermediate piece 21 and the Inner wall 31 including the associated parts in the direction of arrow 73 has the consequence that in relation to the connection between the extension 45 of the intermediate piece 21 and the part or its outer wall 32 are those shown in FIGS. 5-8 Positions of the individual parts are given, i.e. that intermediate piece 21 with extension 45 can be pulled upward out of part 23 or its outer wall 32. The at-rabbits-60 happen the respective passage 59 of the two breakthroughs

chungen 55. Furthermore, the extension 45 can easily be lifted off the two webs 62 of the inner wall 31. The inner wall remains in its end position shown in FIGS. 5-8, which at the same time corresponds to the pivoted position of the two plug contacts 25 shown in FIG. 3 of the drawing. These plug contacts 25 assume an inclined position with respect to the recess 71 into which the plug 26 can be inserted, so that when the device is open or the storage body 28 is removed, a conductive connection between the device and a voltage source via plug contacts is not possible 25 and plug 26 to manufacture. On the other hand, this means that turning the "two parts 31 and 32 in the sense of opening the device is not possible as long as the plug 26 is located within the recess 71. JSs is therefore necessary: the connection by removing the plug 26 from the To solve recess 71 before the device can be opened.

The rotary movement can be limited by stops at suitable points, preferably in the area 57 of the recess 55. It is also possible that an extension in the holder 70 abuts against an associated stop 77 or that the plug contacts 25 abut the wall of the recess 71 and thus limit the rotary movement.

Fig. 11 of the drawing shows the extension 45 of the intermediate 21 hanging storage body 28 after this from the

Part 23 pulled out upwards or the part 23 pulled off downwards has been. There is now the possibility of using the Intermediate piece 21 and optionally lidske 20, which can be detached from the Zxvischenstück 21 is attached to be introduced into a special container 7θ, which has an annular space 77, the dimensions of which. - Those of the hollow cylindrical storage body 28 are adapted.
