Abstract

The invention relates to a device for discharging intestinal or other malodorous gases in a manner as odorless as possible as a component of a system for discharging and / or collecting feces or other excretions or secretions which produce strong odors from the human or animal body in a closed, preferably continuous manner, wherein the feces or the discharged excretions or secretions are guided in a tube-like or pipe-like structure outside the body, which has, in addition to the inlet and outlet connections and the channel region connecting the two for the passage of the feces or other excretions or secretions, a branch in which the intestinal or other malodorous gases are separated from the feces or other excretions or secretions and guided by means of an adsorption and / or filter device to an outlet, wherein the adsorption and / or filter device is at least partially spaced apart from the channel region in order to avoid as far as possible intensive contact with the feces or other excretions or secretions flowing through the channel region.

Description

TECHNICAL FIELD

[0001] The invention describes a device for the discharge of intestinal or other malodorous gases in a manner as odorless as possible as a component of a system for the closed, preferably continuous, discharge and / or collection of feces or other excretions or secretions with a strong odor from the human or animal body, wherein the feces or the discharged excretions or secretions are guided downstream in a tube-like or pipe-like drainage line to a collection container outside the body. BACKGROUND

[0002] Devices for the continuous discharge of feces from the rectum of a patient are an established component of modern medicine and care. The known defecation systems today usually have a ring- or balloon-like head unit which anchors (resides) the respective device in the rectum of the patient. In addition, the head unit also has a soft tube assembly which accommodates the feces in the rectum and guides it through the anus or anal sphincter, on which the ring- or balloon element which resides in the rectum is fixed at the distal end. The head unit which fixes the rectum and discharges the feces through the anus is followed by another extracorporeal soft tube section which further transfers the feces from the patient's body to a usually bag-like collection container which is usually mounted on a bed frame below the level of the patient, so that the feces flows out following the slope. The bag is usually replaceable and has a closure system for the corresponding manual connection to the drainage unit. The connection can be implemented, for example, as a bayonet closure. The feces collection bag usually has a gas removal function or assembly which discharges the intestinal gases produced in the patient's intestine from the drainage system to the environment or avoids the accumulation of intestinal gases in the abdomen by constantly de-pressurizing the drainage system towards the environment. A sufficient de-pressurization of the intestinal gases is of high clinical relevance during application, since intestinal gases can accumulate in the upper small intestine and trigger symptoms of ileus. The distension caused by the accumulation can also lead to impaired diaphragmatic activity and thus impair the mechanical ventilation of the patient. The gas removal function or assembly of the bag is usually equipped with a sorber or filter which absorbs the feces, malodorous or other unpleasant odors.

[0003] The feces drainage devices of the conventional construction type usually cannot ensure sufficient de-pressurization or odor absorption (sorption) when the amount of gas to be discharged is large or the odor of the feces is particularly strong. This is usually caused by an insufficient amount of sorption or filter material, but can also be caused by the typical positioning of the gas removal assembly in the feces collection chamber of the collection bag. The gas removal function of the filter integrated in the bag wall can be impaired by a brief lying of the bag, which often occurs, for example, when the patient is being transported or positioned. When the bag is in the lying position, the contents of the bag reach the gas removal assembly and dirty or wet its interior, which can limit the de-pressurization capacity of the entire system. In addition, the filter or sorption material used accordingly can also be soaked with liquid and thus permanently lose the gas removal, de-pressurization function. SUMMARY

[0004] The problem underlying the present application, which arises from the drawbacks of the prior art described, is to ensure that the odour nuisance caused by the device is as little as possible, in the framework of a device of the same type for evacuating and / or collecting faeces or other excreta or secretions of strong odour.

[0005] The solution to the problem described above, in the framework of a device of the same type, consists in inserting a tubular or pipe-like structure upstream of the collection compartment of the collection container, which, in addition to the introduction and evacuation joints and the passage area connecting the two together for the passage of faeces or other excreta or secretions, has a branch in which the intestinal or other malodorous gases are separated from the faeces or other excreta or secretions and directed to the outlet by means of adsorption and / or absorption and / or filtering means.

[0006] The present application thus describes a device for adsorbing and / or filtering gases of strong odour formed in the body, which is integrated, for example, in a system for evacuating and collecting faeces continuously and hermetically or for evacuating other excreta or secretions of strong odour. The device is designed in particular for a continuous and efficient de-gassing function, independent of the positioning. In this case, the evacuated excreta or secretions are guided in some way through the tubular, pipe-like or T-piece-like basic element of the device, so that, when the device is in the normal position, which is substantially vertical, the contamination of or closure of the components that evacuate the gases to the environment can be avoided as much as possible, and the accumulation of intestinal gases in the system, for example, can be prevented. The device can be optionally fixedly integrated into the system or, if necessary, can also be installed by the user as an airtight connectable additional unit to the system. The device preferably has a separation layer directed towards the adsorbing and / or filtering medium, which repels liquids and / or faeces but is permeable to gases. The adsorbing and / or filtering medium is optionally integrated into the device in a fixed or removable, replaceable structural form. The device is positioned between the evacuation conduit and the collection bag unit, so that it is not continuously exposed to the contents of the bag. The collection bag has an anti-backflow function, which keeps the material that has entered the bag there even if the bag is transitioned from the normal position, which is vertical, to the lying position. In addition, the device also ensures that the gases that have penetrated into the collection chamber of the container overcome the anti-backflow function integrated in the container and are transported to the gas evacuation device located upstream of the collection container.

[0007] In a preferred embodiment, the device described within the scope of the present application for discharging the amount of gas formed in the body has a basic element in the form of a T-piece, wherein the upper, distal portion of the T-piece, which faces the patient, is directly opposite the lower, proximal portion of the T-piece, which faces the collection bag, in the axial extension. In a preferred embodiment, the free lateral leg of the T-piece, which faces the environment and is open, accommodates an odor adsorption and / or filter unit filled with a corresponding substance, for example based on activated carbon. In addition to surface-active substances, which accumulate and adsorb odor substances on the surface, adsorbing substances are also considered, which absorb odor substances in the form of a physical "solution". The unit can be connected to the lateral leg in a fixed structure or by means of a corresponding connection, for example plugged onto the leg.

[0008] It is essential for the function of the present application that the intestinal gas can escape unhindered and effectively from the system even in the case of a larger amount of gas, when the degassing means is normally and vertically positioned in the defecation system. If the vertical normal position of the means is changed to a temporary horizontal position, the closure of the components required for degassing by the feces should be avoided as effectively as possible. Within the scope of the present application, the adsorption and / or filter material is separated from the feces discharged in the hose line and collected in the bag by different structural features. The present application describes the basic structural form of the device, wherein the content that has been guided into the collection container or collection bag is prevented from flowing back to the degassing means in the horizontal position, for example by a membrane-based anti-backlash lip or sail-like component, and in principle the means for degassing the collection container is structurally arranged upstream.

[0009] Within the scope of the present application, the longitudinal direction of the flow channel between the branch and the adsorption and / or absorption and / or filter device forms an angle of 90° or less, for example an angle of 75° or less, preferably an angle of 60° or less, in particular an angle of 45° or less or even an angle of 30° or less, with the longitudinal direction of the channel region between the branch and the discharge connection. If the above-mentioned angle is less than 90°, the longitudinal direction of the flow channel between the branch and the adsorption and / or absorption and / or filter device is preferably inclined upwards, i.e. offset towards the introduction connection.

[0010] The maximum flow cross-section in the region between the branch and the adsorption and / or absorption and / or filter device can be equal to or smaller than the minimum flow cross-section in the channel region. In this case, such a tapering is not a problem, since only gas should flow through the adsorption and / or absorption and / or filter device anyway.

[0011] According to the stated object, the region between the branch and the adsorption and / or absorption and / or filter device should only serve as a flow channel for the gas, it being possible according to the application for the flow cross section in the region between the branch and the adsorption and / or absorption and / or filter device to be narrowed with respect to the smallest flow cross section in the channel region by means of an obstacle which at least provides a solid substance, but preferably also a liquid substance, which has a greater resistance than the gaseous substance.

[0012] This obstacle is preferably constructed as a tongue which is arranged approximately at the height of the branch in the channel region.

[0013] The application can be further improved in that the obstacle is constructed as a tongue which is fixed upstream of the branch and which, in the case of the guidance of excrement or other excretions or secretions, at least partially covers the branch in the channel region against the adsorption and / or absorption and / or filter device. This tongue can be fixed either only at its upstream edge or on both edges adjoining the upstream edge.

[0014] The tongue can be constructed in a flexible and / or elastic manner on a limited circumference and is preferably made of plastic. The tongue should be connected in some way along its fixed edge in such a way that it thereby obtains a preferred direction with respect to the longitudinal direction of the channel region, which, due to its intrinsically sufficiently rigid properties, remains the same regardless of the orientation of the channel region, so that the branch remains open for the gas at all times. The actual purpose of the tongue is to keep the passing excretions or secretions away from the adsorption and / or absorption and / or filter device, but at the same time to allow or facilitate the escape of the gas to the adsorption and / or absorption and / or filter device. A smaller open cross section in the free edge region of the tongue is sufficient for the discharge of the gas. This open cross section can also be ensured by means of one or more lugs or other elevations on the back of the tongue which face the inner cavity branching off from the through-cavity, which ensure a minimum distance between the tongue and the edge of the discharge opening; of course, such lugs can also be arranged in the edge region of the discharge opening and come into contact with the tongue when approaching it.

[0015] The tongue can be integrated with the hose-like or tube-like structure or connected to it by means of adhesive or other joining techniques.

[0016] Furthermore, the transition region between the tongue and the hose-like or tube-like structure is preferably not constructed in a hinged manner, but rather in a more rigid manner, so that the tongue always maintains its orientation in the predetermined direction.

[0017] The tongue can have one or more holes for the passage of gas.

[0018] Furthermore, the entry openings of the adsorption and / or absorption and / or filter device towards the channel region or the branch can be covered by a gas-permeable, but preferably water-repellent separation layer. This is a further measure in order to keep the filter open for gases at all times.

[0019] A preferred refinement of the application is that the separation layer has a surface which is difficult to wet, in particular on its side facing the channel region or the branch (lotus effect), in order to avoid undesired adhesion of excrement or secretion.

[0020] The separation layer can be constructed, for example, as a microporous membrane made of expanded polytetrafluoroethylene, for example, having a maximum pore diameter of less than 1 mm, preferably having a maximum pore diameter of 100 μm or less, in particular having a maximum pore diameter of 10 μm or less.

[0021] On the other hand, the separation layer can also be made of paper, in particular of non-woven paper (Vliespapier).

[0022] Within the scope of the application, the adsorption and / or absorption and / or filter device has one or more surface-active substances which accumulate and adsorb odor substances on the surface and / or one or more adsorbing substances which absorb odor substances in the form of a physical solution.

[0023] The adsorption and / or absorption and / or filter device can comprise, for example, adsorbing or absorbing or filtering particles, for example activated carbon, the amount of which is, for example, 100 ml or less, preferably 50 ml or less, in particular 20 ml or less, or 10 ml or less, or even 5 ml or less.

[0024] The application proposes that the adsorption and / or absorption and / or filter device contains particles, for example activated carbon, in an amount of 2 ml or more, preferably 5 ml or more, in particular 10 ml or more, or 20 ml or more, or even 30 ml or more.

[0025] In order to guide the gas to be purified in a defined manner through the adsorption and / or absorption and / or filter device, the latter should have one or more lamellar structures inside it which can assume the function of walls in a labyrinth.

[0026] A particularly good cleaning or filtering effect is achieved when the gas to be cleaned is guided through the adsorption and / or absorption and / or filter device in a path which is as long as possible. This can be achieved, in particular, by the lamellar structures being offset relative to one another and / or engaging one another in the form of overlapping fingers.

[0027] A further way of achieving as long a path as possible for the gas to be cleaned within the adsorption and / or absorption and / or filter device consists in that the adsorption and / or absorption and / or filter device has at least one spiral, helical and / or spiral-shaped structure inside it, so that the gas is forced to flow along said spiral, helical and / or spiral-shaped structure.

[0028] The application can be further improved in that the adsorption and / or absorption and / or filter device has a material that filters infectious pathogens, in particular in the region of its downstream or outlet-side opening. By this measure the spread of diseases can be limited.

[0029] If the adsorption and / or absorption and / or filter device is arranged in a replaceable cartridge or detachable cover, the cartridge or cover can be replaced by a new one without any effort after the adsorption and / or absorption and / or filter material has been used up.

[0030] The replaceable cartridge or detachable cover should have one or more discharge openings in the region of its free end side or its circumference, where the cleaned or filtered gas can escape into the environment.

[0031] If the replaceable cartridge or detachable cover can be connected to the hose-like or tube-like structure downstream of its branch by means of a bayonet closure or screw closure, the replacement of the used cartridge or cover is particularly easy.

[0032] The replaceable cartridge or detachable cover can also optionally be connected to the introduction joint of the hose-like or tube-like structure by means of its closure, so that the cartridge or cover can be applied as an odor-tight closure to the introduction joint to clean a filled collection bag.

[0033] In further compliance with the idea of the application, it can be provided that the hose-like or tube-like structure and / or the replaceable cartridge and / or the detachable cover has at least one compartment for accommodating an aromatic substance. By means of this aromatic substance the spatial atmosphere can be improved on the one hand; however, especially to mask odors that can not have been completely filtered out.

[0034] The compartment for accommodating an aromatic substance can be open towards the outside. However, in order to release the aromatic substance as far as possible only during the use of the device according to the application, the compartment for accommodating an aromatic substance can be closed by means of a removable covering, for example in the form of a release film.

[0035] The application can be further improved in that the compartment for accommodating an aromatic substance is ring-shaped and ring-shapedly surrounds the central discharge opening of the adsorption and / or absorption and / or filter device.

[0036] Within the framework of this embodiment, a wick or a non-woven and / or large-mesh and / or large-pore fabric can be arranged in the central opening of the annular compartment for accommodating the fragrance substance, for example a wick which is stretched transversely over the central opening or a non-woven and / or large-mesh and / or large-pore fabric which extends into the compartment containing the fragrance substance in order to be moistened by means of the fragrance substance.

[0037] Furthermore, the hose-like or tube-like structure can have a bayonet closure or a screw closure at its introduction joint and / or discharge joint for connecting a hose or a collecting container or a collecting bag or the like.

[0038] Furthermore, the hose-like or tube-like structure can be integrated with a collecting container or a collecting bag, in particular in the region of its introduction joint.

[0039] On the other hand, the hose or tube-like structure can also have a hose or tube extension which communicates with the adsorption and / or absorption and / or filter device from the discharge side thereof via a branch.

[0040] This hose or tube extension which communicates with the adsorption and / or absorption and / or filter device can extend into the collecting container or collecting bag, in particular up to a backflow-inhibiting membrane or another backflow-inhibiting structure located there.

[0041] Furthermore, the hose-like or tube-like structure can be integrated with or connected to a head unit which can be anchored or can be anchored in the rectum of a patient, said head unit being anchorable in the rectum by means of a balloon element which can be placed or is placed in the rectum.

[0042] Furthermore, during the permanent application of the defecation system, the defecation hose arranged between the patient and the bag also produces odours, wherein in particular the barrier properties of the hose material used are of particular importance. Conventional systems which are usually composed of silicone-based materials are not suitable for continuous defecation without additional coating, for example by means of a parylene substance, without odour permeation. The poor barrier properties of silicone are caused by the significant porosity of the silicone used. Complex coatings of the silicone surface also usually do not provide sufficient odour barrier effects. New silicone-based systems have recently been launched which have a special inner hose which is manufactured separately from the nylon or Teflon material and is installed as a separate component, thereby enabling a significant improvement in odour barrier properties.

[0043] As an alternative to silicone-based hose components, cost-effective PVC-based or co-extruded with a PVC layer hose materials can also be used for improving the odour seal. The barrier effect of these hose materials is sufficient for most faeces even without the use of additional coating or inner hose technology.

[0044] Therefore, the described device for the pressure reduction of intestinal gases and for the adsorption of odoriferous substances is preferably used in combination with a defecation hose line based on PVC, containing PVC or co-extruded with a PVC layer.

[0045] In order to achieve a minimization of the diffusion of odoriferous substances through the introduction or discharge hose, the hose-like or tube-like structure and / or the collecting container integrated therewith or connectable therewith and / or the collecting bag integrated therewith or connectable therewith and / or the hose or head unit integrated therewith or connectable therewith can be composed of a material based on PVC, containing PVC or coated with one or more PVC layers or co-extruded with one or more PVC layers.

[0046] In terms of construction, the device according to the application can be arranged in series or in parallel with a defecation system.

[0047] The hose-like or tube-like structure preferably has a T-shape.

[0048] It is further proposed within the scope of the application that the discharged feces or the discharged excretions or secretions are guided in a certain way through the hose-like or tube-like or T-shaped structure of the device, so that, when the device is in the normal position approximately vertically, contamination or clogging of the gas discharge assembly of the device is avoided as far as possible, wherein in particular an accumulation of intestinal gases within the system can be avoided, for example. In this case, the basic idea of the application is that the feces or other excretions or secretions are guided through the drainage line to the collecting container under the influence of gravity during the drainage process. Therefore, for the operation of the system, a vertical orientation of the device is preferred, and a vertical orientation of the collecting container is also preferred. Precautions are taken for the vertical orientation in order to avoid contamination or clogging of the gas discharge assembly of the device as far as possible.

[0049] In order to ensure this vertical orientation of the collecting bag, the application proposes that a hook for vertically hanging the collecting bag is provided on the hose-like or tube-like or T-shaped structure.

[0050] The improvement is further made in such a way that the hook is constructed in such a way as to protrude to such an extent that, when the collecting bag is lying flat, the hose-like or tube-like or T-shaped structure connected to the collecting bag is thereby still inclined upwards in the direction of the upstream, so that, despite the fact that the odor closure according to the application is not oriented completely vertically, it still functions properly.

[0051] Finally, according to the technical principle of the present application, the hooks are constructed as double-sided hooks projecting in the diametrical direction or as holding brackets that can be rotated around the longitudinal axis of the hose-like or tube-like or T-shaped structure and are optionally snapped into a pre-set position. Thus, it is not important for the working mode in which side the collecting bag is placed; the hose-like or tube-like or T-shaped structure connected to the collecting bag is always aligned with the sufficiently vertical assembly in order to ensure the working mode of the odor closure. In the case of double-sided hooks projecting from the flat surface of the collecting bag, the user does not have to worry about it by the sufficiently vertical arrangement; in the case of rotatably adjustable hooks, the user has to ensure that the hooks are pivoted towards the flat surface of the collecting bag located below.

[0066] Figure 1a An excrement discharge apparatus 1 is shown, which discharges intestinal gas into the environment, said apparatus being arranged as a separate modular unit between the bag-side end 2 of the drainage line 12 and the faecal matter containing inlet 3 of the collecting bag 13. The apparatus 1 has at the respective ends connection assemblies 2a and 3a pointing towards the drainage line 12 and the collecting bag 13, for inserting the apparatus 1 in a series arrangement into the faecal matter drainage system, preferably in the transition from the drainage section to the collecting bag 3 or the faecal matter containing container. The basic element 4 connects the connection assemblies 2a and 3a together in such a way that they are in a connection in communication with each other.

[0067] The degassing, adsorbing and / or filtering module 5 is mounted on the outer circumference of the wall portion of the tubular cylindrical base element 4 of the device in a reversible and detachable manner or in a form of a firm connection with the base element 4. The module 5 is attached to the wall portion of the base element 4 in a ring-shaped closed manner as a skin bowl or as an unclosed C-shaped housing. In the area of the connection of the filter module 5, the base element 4 has one or more openings 6, which are adjoined by a gap-like intermediate interspace 6a, which is defined towards the adsorbing or filtering material by a water-impermeable and gas-permeable separating layer 7. The separating layer 7 can consist, for example, of a GoreTex type material, which can be supplemented on the side towards the intermediate interspace 6a by a dirt-repellent effect, for example a lotus effect. As an alternative, a cost-effective HME filter typical non-woven paper can be used as the separating layer 7, which also has a water-repellent effect and at the same time a gas-permeable effect. Conceptually, the side of the separating layer 7 towards the feces is preferably designed in such a way that exposure to feces does not cause a permanent gas-tight closure of the separating layer 7. Preferably, at the lower end of the intermediate interspace 6a pointing towards the bag 13, the intermediate interspace transitions through an opening 6b into the feces guiding or defecation chamber of the base element 4. Thus, feces entering the intermediate interspace 6a through the opening 6 can flow back into the inner cavity of the base element 4 through the opening 6b. In a variant of the described construction, the defecation guiding cavity of the base element 4 can also be connected to the intermediate interspace 6a only through the opening 6b, i.e. without the opening 6. In this case, the intermediate interspace 6a extends chimney-like upwards from the opening 6b, so that, in the normal position of the device 1 in the vertical position, the separating layer 7 located above the opening 6b is protected from direct exposure to feces.

[0068] Figure 1bAn embodiment with a T-shaped basic element 4 is shown, the basic element 4 having an open side leg 9 facing the environment, on which an adsorption and / or filtration module 5 is mounted. In a preferred embodiment of this structure, the side leg 9 is oriented upwards or upstream along the drainage direction at an angle N of approximately 15 to 60 degrees, preferably 30 to 45 degrees, to the vertical line or longitudinal axis of the basic element 4. Thus, when the device 1 or the unit consisting of the defecation drainage hose 12, the degassing device 1, and the collection bag 13 is in its normal, suspended, nearly vertical position, the module 5 is protected from direct flow of feces. Feces that have penetrated into the side leg 9 can be discharged from there, following the inclination of the side leg 9, into the inner cavity of the basic element 4. In addition to the described inclination of the degassing side leg, the transition to the feces guiding inner cavity of the basic element 4 can be protected by a tongue 4a in the form of a curtain or canopy structure to more effectively prevent feces from entering the degassing side leg 9. The tongue 4a serves as a shielding structure, for example, in the transition region 4b between the laterally facing side 9 and the vertically upward or upstream extending side of the T-shaped basic element 4. It originates from the inner wall of the basic element 4 and extends downward through the lower transition portion 4c of the laterally facing side 9 to enter the vertically downward or downstream extending side of the T-shaped basic element 4.

[0069] As an alternative to positioning the modular device 5 between the drainage line 12 and the collection bag 13 as a functional unit that can be connected in series as needed, the basic element 4 can also be directly integrated into the upper inlet area 3 of the collection container 13 in a fixed structure. In the case of using a bag-shaped container 13, the membrane of the container is sealed together with the downward-oriented edges of the T-shaped piece facing the bag 13 by direct welding or bonding.

[0070] Figure 1c The basis for showing device 1 Figure 1b In this embodiment, the adsorption and / or filtration material has been integrated in a fixed structure into the transverse exhaust foot 9 of the T-shaped basic element 4, which is open to the environment and consists of a drainage section 12 and a bag 13. In this case, the foot is sized in a certain way such that it can, for example, accommodate approximately 5 to 10 ml of activated carbon particles. The carbon particles are separated from the upper and lower feet of the T-shaped basic element 4, which guide feces, by a breathable and hydrophobic separation layer 7. The end opening of the foot 9 is provided with a cap-like closure having an opening 5a for venting gas to the environment.

[0071] Figure 2One embodiment of the device 1 is shown, wherein the outlet for intestinal gas is formed by a flexible or tubular insert 10, which is inserted into the defecation unit. The insert 10 is introduced through an opening 11 designed in a precisely fitting manner, which is closed, for example, by a cover-like element when not in use. In a preferred embodiment, the distal end of the insert 10 is pushed into the fecal-containing internal space of a bag 13, wherein the bag protrudes beyond a backflow-inhibiting membrane layer 13a such that these membranes do not impede the backflow of gas from the bag 13, thereby allowing gas already inside the bag to be expelled into the environment. The proximal end of the insert 10 has a fixedly mounted suction and / or filter module 5 at its distal end. Insertion may be achieved, optionally in the region 2 near the bag of the defecation catheter tubing 12, but preferably in the connection region between the drainage catheter 12 and the collection bag 13, for example, through an opening integrated into a corresponding connector or a corresponding portion of the connector. In a preferred embodiment, the insert 10 has an opening 10a with the largest possible internal cavity, which communicates with the fecal guiding chamber above the backflow-inhibiting membrane 13a. The flexible or tubular portion of the insertion part 10b is preferably equipped with a small inner cavity to limit the backflow of liquid contents. The insertion part extends out of the anti-backflow membrane into the collection chamber of the bag 13. The module 5 is positioned approximately 10 cm above the opening 11 to avoid contamination by the bag contents when the bag 13 is in its normal vertical position.

[0072] Figure 3a Showing the exhaust device 1 and Figure 1b In a comparable embodiment, the device has a T-shaped basic element 4, wherein a module 5 containing adsorbent and / or filter material is hermetically attached to a lateral foot 9. The module 5 has an internal sheet-like structure 16 that guides gas flowing from the system from the bottom 14 through the module contents to the top 15 of the module as efficiently as possible, while making the best use of odor binding and / or filtering capabilities. The sheets 16 may be horizontally staggered, interlocked in a finger-like manner, or guided in a spiral or helical manner. Preferably, the module 5 is arranged relative to the basic element 4 in such a way that the leverage force acting through the module 5 on the unit consisting of the drainage conduit 12, the degassing device 1, and the collection bag 13 is kept as small as possible, thereby preventing the normally suspended unit from tipping over. The module 5 should have a correspondingly flat structure that is as close as possible to the basic element 4 and as close as possible to the center of gravity. The activated carbon content in the module 5 of the described structure should be 20 to 100 ml, preferably 30 to 50 ml.

[0073] Figure 3b Showing according to Figure 1aa combination of an adsorber or filter fixedly installed in the lateral leg 9, wherein an additional filter and / or adsorption cartridge 5b can be plugged onto the leg 9 as an additional unit in a reversible and releasable manner. The cartridge 5b is equipped with a sealing lip or O-ring seal 5c to optimize the sealing in the joint area between the leg 9 and the cartridge 5b. The gas escaping from the leg 9 at the end side is sucked through the corresponding opening 5d in the socket-like recess in the bottom of the cartridge 5b and, in the sense of achieving as efficient an adsorption as possible, is guided through the adsorption or filter material by the lamellar connecting plate 16. In order to prevent bacteria or viruses from escaping from the system into the environment, a filter material 5e that is impermeable to spores, bacteria and viruses is provided upstream of the discharge opening of the cartridge top cover.

[0074] Figure 3c A special form of gas conduction through the filter or adsorption material is shown, wherein the interior of the module 5 is equipped with a helical or spiral separating wall 16a, which expands from the center or from the inlet opening outwards and opens at the end towards the environment through another opening 17. In order to avoid the escape of infectious pathogens such as virus or bacterial spores, a corresponding filter material 5e is provided upstream of the opening 17.

[0075] Figure 4 A flexible or rigid component 21 in the form of a hose or tube is shown, the end 21a of which facing the patient is fixedly installed on the inner wall of the basic element 4, preferably in the region of the lateral leg 9, and the proximal end 21b of which dips into the feces collection chamber of the collection container 13 at the lower end of the basic element 4. In this case, the component 21 can overcome a counteracting component, for example a sheet-like membrane layer 13a that abuts against each other tightly and functions valve-like, so that the intestinal gas penetrating into the bag 13 can be evacuated through the inner cavity of the component 21 and / or along the outside of the component 21, preferably directly into the exhaust leg 9 of the device 1.

[0076] Figure 5A further structural form of the device 1 according to the application is shown, in which the T-shaped basic element 4 is fixedly integrated into the inlet portion 3 of the bag 13, preferably welded or bonded thereto. The lateral leg 9 is equipped with a bayonet closure mechanism 9a, which corresponds to the closure mechanism 2a for connecting the drainage catheter 12 to the bag 13. During the faecal collection phase, the lateral leg 9 is closed by means of a cover 19. The cover 19 integrates a cartridge 20 with a filter material 21 based on activated carbon. According to the preceding embodiment, the free opening of the leg 9 is equipped with a gas-permeable, water-repellent and / or dirt-repellent separation layer 7, which prevents faeces from escaping from the T-shaped basic element 4. The cover 19 is connected to the leg 9 in a gas-tight manner. The cover 19 has an opening 22 for venting at the end. As an alternative to the cartridge, the interior space of the cover 19 can be directly filled with carbon or adsorbing or filtering material, wherein the filled space can be closed on both sides 23a and 23b, for example, by means of a stable, gas-permeable separation layer made of a porous sintered material. In the case of activated carbon, the interior volume is 4 to 10 ml, preferably 5 to 6 ml.

[0077] If the bag 13 is separated from the drainage 12 and cleaned, the cover 19 is separated from the leg 9, placed onto the joint 2a and closed there. The separation layer 7 then prevents liquid from flowing freely through the lateral leg 9.

[0078] Furthermore, in order to make it difficult for the discharged faeces to penetrate into the lateral leg 9, a tongue 4a in the form of a curtain or a siphon-like structure is also installed in the T-shaped basic element 4, which protects the transition from the faecal guide path to the lateral branch leg 9.

[0079] In order to discharge intestinal gases that have penetrated into the collection chamber of the bag 13 or by means of a backflush-inhibiting function, for example a backflush-inhibiting film layer 13a, integrated in the collection bag 13, the gases are fed back into the T-shaped basic element 4 upstream of the backflush-inhibiting device and discharged from there through the adsorber and / or filter 5 to the environment, the T-shaped basic element 4 having a rod-, tube- or hose-like extension 25 at its proximal end, which penetrates deep into the collection bag 13 beyond the backflush-inhibiting film or other function. The profile of the extension 25 is designed in such a way that gases can be guided from the collection interior of the bag 13 around or through the extension 25 into the region upstream of the bag 13. Thus, in the described structural form with the T-shaped basic element 4 fixedly integrated into the inlet portion 3 of the bag 13, the outlet commonly used in conventional collection bags 13, which is directly integrated into the bag wall, can advantageously be dispensed with. The outlet assembly integrated into the wall of the collection compartment is particularly problematic if the collection bag 13 is in a lying position and the bag contents subsequently wet or soak through the filter as required, so that the filter partially or completely loses its gas-removing function.

[0080] Figure 6a A modified structural form of the module 5, 5b is shown, which, in addition to having an adsorbing and / or filtering effect, also has the function of releasing fragrance substances. Substances having a scenting or masking of unpleasant odour effect are released from a compartment 26, which is integrated into the housing of the module 5, but is continuously separated from the adsorbing or filtering medium of the module. Embedded in the compartment 26 is a storage assembly 27 having absorbency, which is made of, for example, a multi-layered pressed cellulose, which accommodates scent substances on its respective larger total surface and releases them in a delayed manner on its front surface facing the environment. The compartment 26 can be sealed by means of a release film 28. The scent substances can also be released from separate, for example, capsule-like containers 28, which are inserted into corresponding slot-like recesses of the module 5. The respective scent substances can be selected by the user from a plurality of scent variants and replaced.

[0081] Figure 6b An additional dispenser module 29 is described, which is placed directly on the exhaust opening 30 of the device 1 or the T-shaped basic element 4 or arranged directly downstream of the opening and continuously releases neutralising odour fragrance substances in the immediate outlet area of the device 1 by means of an integrated substance release function. In this particular embodiment, the intestinal gases escaping from the device 1 or the entire faecal drainage system through the exhaust opening 30 are passed through a vlies-artiges, large-pored or large-meshed fabric 31, which absorbs the fragrance substances from a storage assembly 32 in a wick-like manner and releases them into the escaping gases through the respective larger surface of the porous or mesh-like structure of the vlies-artiges fabric, thereby masking the odorous components of the gases by the respective effective scent.

[0082] The released fragrance substances are preferably based on a volatile oil-based solution, which has sufficiently good working properties in the vlies-artigen fabric in which it is released. The reservoir 32 connected to the vlies-artigen fabric 31 is composed of, for example, a felt-like or sponge-like assembly and can optionally be added with fragrance substances from the outside, for example through an ampoule-like container, which can be squeezed between the fingers, directly before the combination of the module 5 with the drainage device 1 or the T-shaped basic element 4, through the small-lumen opening 33. In the case of this kind of system, the user can select between a plurality of scent variants. Furthermore, the user can also remove the module 5 from the bag 13 or the system and transfer it to the new bag 13 or the new system when changing the collection bag 13 or the entire system. The module 5 can thus be used for the patient for the entire duration of use of the drainage device 1. If the reservoir is empty, it can be refilled with fragrance substances through the opening.

[0083] Therefore, the invention describes a device for binding and / or filtering gases, which can be used as an attachment or firmly integrated into a system for discharging feces or other secretions or excretions, which accumulate within the feces drainage system, for example, in the case of continuous, closed feces drainage, and wherein these gases are discharged or depressurized to the environment without releasing unpleasant odors, wherein the device is arranged in series or parallel in terms of structure with the defecation system, wherein the gases are discharged to the environment outside the collection chamber of the collection container 13 and the corresponding exhaust assembly or function is not contaminated by the collected contents and thus unable to work.

[0084] The gases are preferably discharged to the environment located directly above the collection chamber, for example, in the defecation hose of the system into the collection chamber.

[0085] The gases that have penetrated into the collection chamber of the container 13 can be discharged into the area of the gas outlet and depressurized therefrom, for example, by a rod-shaped, tubular or hose-shaped extension.

[0086] The exhaust function of the filter and / or adsorber material is maintained by a dirt- and / or water-repellent separation layer between the defecation interior of the device and the corresponding connected filter or adsorber module 5.

[0087] Figure 7 A special embodiment is shown with a valve-like double-layer membrane with a flow- guiding effect, which allows the gases to flow back from the collection container 13 into the system leading to the bag.

[0088] Figure 8 An angular holding device is shown for fixing the bag in a vertically hanging position, wherein the bag contents are difficult to flow back into the system leading to the bag when the bag is temporarily in a lying position.

[0089] Figure 7Valve-like arrangement with flow guiding effect of the double film layers 13ax and 13ay, which are arranged in the interior of the collection container 13, is shown, which are arranged in a plane against each other. The material M, which is discharged into the collection container, passes through both film layers into the collection chamber S of the container. If the container is filled in the normal position of vertical suspension or vertical standing up to the height of the two film layers or beyond, the liquid content causes a lip-like closure of the film layers and prevents the content from flowing out or backflowing undesirably from the collection container through the introduction opening. A corresponding effect occurs when gaseous substances enter the collection container. The gas filling also causes a sealing closure of the two film layers, whereby the gas gradually accumulates in the container and the resulting closing pressure exerted on the two film layers is so significant that the liquid content can no longer flow further into the collection container. If no corresponding structural modification of the counterblast function is made, the collection container must be replaced in this case. In order to discharge the gas, which has penetrated into the bag, from the bag, the invention proposes film layers, which are implemented in a special way, which are liquid-tight but allow the gas to pass freely. These film layers can be made entirely, for example, of the corresponding material in a plane or only partially have the corresponding properties in certain sections. Advantageously, the gas-permeable function or unit is placed at a location where the two film layers cannot be completely closed due to mechanical reasons even in the case of maximum filling of the container. This is the case in the connection or transition region 3a of the film layers to the tubular or joint-like inlet or connector section, where the sealing film layers are, for example, welded or bonded. In the case of an outer diameter of the introduction element of approximately 15 to 25 mm, a wedge-shaped open area Z is usually provided, which is not closed even in the case of maximum filling of the container, the height of which is at least 5 to 15 mm, in turn providing sufficient area for the integration of the described function or "gas-permeable separation layer" T. As an alternative to the gas-permeable film material, a small free opening O can also be provided in the wedge-shaped area Z, for example, with a diameter of 1 to 2 mm. However, a simple or cross-shaped slit is preferably implemented in the described wedge-shaped area by means of a sharp blade, wherein the legs of this slit each have a length of approximately 5 mm. Although the slit cannot completely prevent the backflow of the content into the section above the collection chamber, a backflow of a larger volume of the collected content can be avoided.

[0090] Figure 8One embodiment of the bag-like collecting container 13 is shown, in which in the horizontal position of the bag 13, the bag contents are made difficult to flow out into the introduction section 4 of the bag 13 or the outflow of the bag contents is reduced or prevented by the ramp-like slope R of the introduction section 4. For this purpose, the angled hook 34 for vertically hanging the bag 13 is implemented in such a way that the introduction or exhaust section 4 is in an obliquely upward position relative to the lying bag 13. The resulting slope ensures that the liquid bag contents do not reach the exhaust opening L in the introduction section 4 of the collecting bag 13 as far as possible after a certain phase of the lying bag 13. The angled hook 34 is preferably implemented bilaterally towards the two flat surfaces of the bag 13, for example from two layers of welding, so that in any case of the lying bag 13, the desired inclination is achieved. In the preferred construction, the hook 34 or double hook is mounted in a fixed 90-degree angle to the bag surface. The 90-degree position required for the inclination can also be achieved by an axially rotatable holding bracket, which can be pivoted into the 90-degree position and latched there.
