Definitions
- the invention relates to a fluid receptacle for a portable on the body of a user and additionally operable stationary device for providing negative pressure for medical applications, in particular for the negative pressure treatment of wounds on the human or animal body, wherein the device comprises a first housing part with a negative pressure generating device and after Use disposable container for receiving body fluids in its interior, in particular extracted from a wound wound secretions, wherein the container forms a second housing part of the device and on the first housing part of the device manually attachable and manually releasable and in the attached state, the interior of the Can be acted upon by the vacuum generating device container with negative pressure, and wherein the container is provided a connection for a suction line leading to the body, so that a Unterbuchkommunikatio n between the negative pressure generating device, the container and the body leading to the suction line, the container having a trained for manually gripping the second housing part engagement opening, wherein an inner volume of the container also in a region adjacent to a wall defining the engagement opening and in particular
- negative pressure treatment means that a body or wound area exposed to the surrounding atmosphere is closed in a pressure-tight or vacuum-tight manner against the environment, that is to say the atmosphere in which we live and breathe, with an opposite one inside the closed wound area the atmospheric pressure reduced pressure, therefore, so vacuum applied relative to the atmosphere and can be permanently maintained.
- negative pressure is mentioned in the field under discussion, this is understood to mean a pressure range which is typically between 0 and 250 mmHg (mm of mercury) below the ambient atmospheric pressure. It has been shown that this is beneficial to wound healing.
- a vacuum dressing is provided for the vacuum-tight seal, which may comprise, for example, a pressure or vacuum-tight film layer typically adhered to an intact body area surrounding the wound so that a tight seal can be achieved.
- the aforementioned engagement opening in the container could be formed as a kind of recessed grip or as passing through the second housing part through-opening, which facilitates the secure gripping of the container.
- Such a device for providing negative pressure is previously known from DE 10 2009 038 130 A1 of the applicant.
- the engagement opening on the one hand can serve for gripping the second housing part of the device forming container for the purpose of fixing the container to the first housing part or for releasing the container from the first housing part and can also serve to manually grasp the entire device with the second housing part fixed in order to transfer it from one place to another or to carry it around like a handbag or to suit the user's body in a suitable manner, in particular by means of fasteners specifically provided for this purpose, such as straps, To fix buckles, shackles or the like or to position for this.
- the handle is positioned in an upper region of the container forming the second housing part of the device and thereby approximately above a center of gravity of the container and preferably also of the device, so that the container or the device is comfortable and with as little as possible Force can be manually held.
- fingers of one hand extend into or through the engagement opening and the palm of the hand encloses a grip area above the engagement opening.
- the container is largely hollow, so preferably formed free of massive volume ranges; This saves weight and material and is suitable for injection molding in clamshell technology. Since the container is intended for receiving body fluids, there is the problem that when tilting the device, in particular in mobile operation or when fixing or loosening the container, the body fluid taken in its interior tends to flow following the gravity. This results in the liquid also entering and wetting or adhering to areas close to the engagement opening, which leads to unpleasant notions in transparent or at least not completely opaque materials, when the user manually grips the container or the container and in particular the area of the engagement opening consideration, in particular by third parties.
- the present invention has for its object to meet the above-described problems.
- the area adjacent to a wall limiting the engagement opening is formed by at least one chamber in the interior of the container, which is formed so completed that they do not interfere with other, in particular adjacent chambers in Inside the container communicates.
- a foreclosure is provided in the interior of the container, which is not in communication with the remaining liquid-receiving internal volume of the container, that is also separated by pressure and flow.
- liquid absorbed in the interior of the container can not reach the sealed-off region at the engagement opening when the container or device is tilted or changed position.
- the device thus formed gives the impression of a certain distance from parts of the device to be grasped or grasped manually to body fluid accommodated therein.
- the optical appearance and also the acceptance of the device is thereby increased.
- transparent or partially transparent materials can be used in the manufacture of the container, which may be advantageous in some distance from the engagement opening to visually detect the height of the liquid level in the container can.
- the respective sealed-off region extends above a wall bounding the engagement opening. It also proves to be particularly advantageous that the chamber in a plan view of the standing on a flat surface container or on the device in the vertical direction from above viewed completely over the engagement opening upwardly bounding wall. With this further idea of the invention, it is proposed that the extent of the chamber is such that, viewed from vertically above and projecting downwards, it covers the engagement opening. As a result, a complete privacy is given, which prevents the use of transparent or semi-transparent materials inspection of the body fluid stored in the container or at least so indistinct appear that no unpleasant associations are awakened.
- the chamber overhangs the engagement opening above and also to two opposite sides, so that the optically laminating effect of the chamber sealed off from the rest of the interior of the container chamber is further extended to the sides.
- the chamber may also extend adjacent to a side wall limiting the engagement opening.
- the chamber also extends adjacent to a side opening delimiting the engagement opening and is bounded there by a wall bounding a filter chamber.
- an inner wall of the container limits both the filter chamber and the closed chamber provided according to the invention.
- a further chamber not communicating with other chambers in the interior of the container is provided inside the container, which serves for the passage of a flowable medium, in particular flushing medium, to the body or in the direction of the body and, on the one hand, to the first housing part and on the other hand, with a line leading to the body is fluidly connected.
- a flowable medium in particular flushing medium
- the chamber forming the region adjacent to a wall bounding the engagement opening and / or a further chamber not communicating with other chambers in the interior of the container has a component to be protected against moisture, in particular an electronic component, in particular a transponder, Chip, radio, lighting device or the like, receives.
- the container in its interior also has chambers which are characterized in that they communicate with adjacent chambers and are at least partially bounded or partitioned by ribs or web-shaped walls in the interior of the container.
- Such chambers are, on the one hand, a chamber receiving the body fluids in the interior of the container, that is to say a liquid or secretion collection chamber, or a filter receiving chamber or an antechamber which is also preceded by a negative pressure.
- ribs which are formed between adjacent chambers or within chambers, wherein a first type of ribs in a substantially vertical direction, i. H. to about 5 ° to the vertical, and is spaced at least 5 mm from a bottom and wherein a second type of ribs obliquely to the vertical, d. H. is inclined at least about 30 ° to the vertical. It has been shown that by a combination of ribs extending in the vertical direction and ribs extending at an angle thereto, excessive fluid movement and in particular uncontrolled sloshing of fluid in the interior of the container can be effectively prevented.
- the ribs are spaced at least 5 mm from the ground, since in such case the liquid can follow rapidly inside when the container is tilted, which is certainly desirable at least in a lower region of the container to prevent liquid wets a mostly arranged in an upper region filter.
- ribs of a third type are provided in the interior of the container, which form a closed in a circumferential direction wall, so are returned to themselves in the circumferential direction. Such ribs may then form on retracted walls to confine a filter receiving chamber or chamber for conducting media to the body. It would also be conceivable that a plurality of ribs of this third type are arranged concentrically to one another, whereby a splash guard against sloshing liquid, in particular for the protection of a filter, can be achieved.
- ribs are provided which have passage openings, which preferably make up only at most about 15% of their wall surface or have a maximum diameter of 4 mm, in particular of at most 3 mm. Further, it proves to be advantageous if those ribs which are straight or obliquely upwards to a sloping or horizontal wall extending, adjacent there has a through hole. In this case, an air exchange can take place between chambers which are delimited upwards by ribs, which counteracts the formation of bubbles and "bubbling" within the container.
- the container has two mutually adjacent shells, wherein a plurality of particular chambers limiting ribs are perpendicular to the dividing plane of the shells.
- through openings can also be easily formed in terms of process technology in that they are formed by recesses open towards the dividing plane in the ribs.
- a plurality of containers of different liquid receiving volume are provided or kept available. In these containers, then the shell part facing the first housing part is expediently always the same and the other shell part, each with a different receiving volume, in particular with different dimensions, is formed in the direction perpendicular to the dividing plane.

- the container 8 is designed as a disposable disposable article.
- the container 8 comprises above connecting pieces 10, 12 for a suction line, not shown, and a line for supplying media in the direction of the body of the patient or to form a measuring channel.
- the suction line, not shown then leads in the exemplary operation of the device for negative pressure wounds to a wound compressing the wound wound dressing and communicates there, for example via a port, with a wound space to create negative pressure in the wound space, maintain or vary and wound secretions in the Vacuum container 8.
- the container 8 communicates with the negative pressure generating device in the first housing part. 4
- the connecting piece 12 also leads via a line, not shown, which forms a measuring or flushing channel, towards the body of the user, in particular to a wound.
- the connecting piece 12 communicates through the interior of the container 8 with the first housing part 4 and is from there with a supply medium, in particular flushing medium, acted upon or in communication with a measuring connection.
- the interior of the container 8 communicates via a vacuum interface 14 (FIGS. 3, 4a) to be described in more detail below with the vacuum generating device within the first housing part 4, when the container 8 is in the is fixed to the first housing part 4 shown in Figure 1 operating position.
- the container 8 is manually positionable on the first housing part 4 and then manually in a mechanically fixed and mechanically releasable mounting position, in particular latching brought.
- a vacuum communication between the interior of the container 8 and the negative pressure generating device on the one hand and a flow communication between the connection piece 12 and the associated measuring or flushing connection is automatically realized in the first housing part 4, as in principle in DE 10 2009 038 130.9, so that reference will be made thereto for purposes of disclosure.
- Figures 2 to 6 show the formation of the second housing part 6 forming container 8.
- the container 8 comprises a first housing part 4 facing the half-shell part 20 and a second remote from the first housing part 4 in mobile operation to the user's body can be applied second half-shell part 22 ( Figures 5, 6), which together define the interior of the container (8).
- the container 8 further comprises an engagement opening 24, which is formed in the case exemplified as passing through the container 8 through-opening and is formed by two half-shell parts 20, 22 or limited.
- the engagement opening 24 is formed in the first container 8 approximately in an upper quarter and in the middle, so that a center of gravity of the container and the device is located approximately approximately below the engagement opening 24.
- the container 8 and also the entire device can be grasped by manual intervention in the engagement opening 24 with the fingers of a user.
- the user grasps by hand a relatively wide web 26 formed above the engagement opening 24, which forms a grip area.
- an unlocking member 27 ( Figure 1a) operate, so that the container can be released from its operating position shown in Figure 1a on the first housing part 4 and lifted up obliquely. This is also described in DE 2009 038 130.9, so that reference is hereby made to the disclosure.
- the interior of the container 8 extends into a region 28 adjacent to a wall 30 bounding the engagement opening 24.
- this region 28 is formed above a wall 30 delimiting the engagement opening 24 upwardly.
- This region 28 is bounded or formed by a chamber 32 which is thus terminated, i. is partitioned, formed so that it does not communicate with other adjacent chambers or areas inside the container 8. This means that in a liquid collecting chamber 33 in the interior of the container 8 sucked body fluid, in particular from a wound sucked wound secretion, even when tilting or momentary tilting of the container 8 can not penetrate into this chamber 32.
- the chamber 32 forms a kind of privacy in the area of the engagement opening 24 and in the region of the encompassable web 26.
- this chamber 32 overhangs the engagement opening 24 in the vertical direction 34 when viewed from above.
- the chamber 32 also extends in the direction of the arrows 36 to two opposite sides over the engagement opening 24 of time. It can also be seen from FIG. 2 that the chamber 32 also extends adjacent to a wall 38 delimiting the engagement opening 24 laterally. It is bounded outwardly by a wall 42 which forms a chamber 40 for receiving a filter.
- the filter receiving chamber 40 is not completed in terms of flow. It communicates on the one hand with the negative pressure generating device in the first housing part 4 and on the other via a vacuum communicating opening 44 in the wall 42 with an antechamber 45.
- the second half-shell part 22 is formed with respect to the walls perpendicular to the parting plane complementary to the first half-shell part 20 , FIG. 5 shows a wall 42 'which is complementary to the wall 42.
- a negative pressure in the interior of the container 8 can be constructed by the filter not shown in Figures 2-6 and through the opening 44 in the wall 42. Since the connecting piece 10 opens directly into the interior of the container 8, on the one hand a negative pressure can be applied to a wound via the suction line, not shown, and on the other hand body fluid can be sucked from there into the interior of the container 8.
- the further connecting piece 12 opens, viewed from the outside, into a further chamber 48, which is closed off from the remaining interior of the container 8 and is bounded by walls 50 which are closed in the peripheral direction and 50 'of the two half-shell parts 20, 22. From this chamber 48 leads in the depth direction, ie perpendicular to the parting plane, a passage 52 in the direction of the first housing part 4, that is again to the outside of the container eighth
- Figures 3 and 4 show the first half-shell part 20 from the outside, ie with a view to the first housing part 4 in the operating position facing side.
- Figures 3 and 4a show that on the first half-shell part 20 from the outside to seal the chamber 40 for the filter and to seal the through-channel 52, a sealing element 54 and 56 can preferably be molded directly.
- the narrow channel 58 is a feed section of injection molding material, whereby a web 60 connecting the two sealing elements 54, 56 is formed. It can be seen from FIG. 4 a that the sealing elements 54, 56 have an outwardly projecting, concentric, cylindrical section.
- Ribs 70 of a first type extend substantially in the vertical direction 72, that is in the direction of the arrow 34, within the liquid collection chamber 33. They terminate at a distance 74, preferably at least 5 mm, so that the liquid will tilt when the container 8 is inclined can be evenly distributed in the interior of the container with regular suction of the liquid through the connecting piece 10.
- ribs 76 of a second oblique type With the help of these ribs sloshing of the liquid received in the container 8 is prevented in the direction of the filter chamber 40. Such a rib 76 limits the previously mentioned prechamber 45 to the filter chamber 40.
- a relatively small through-hole 82 is formed, which causes a vacuum communication between the prechamber 45 and the rest of the interior of the container 8 and thereby represents a large resistance to penetrating liquid, which could enforce the filter.
- ribs 80 of a third type which are recirculated to each other in the circumferential direction. They form e.g. the wall 42 for the chamber 40 or the wall 50 for the chamber 48. Also, the circumferentially self-guided wall 30 defining the engagement opening 24 may be referred to as rib 80 of the third type.
- a passage opening 84 is provided for pressure equalization and gas passage at the very top, so that no air must be passed through the liquid.
- the two half-shell parts 20, 22 are preferably non-detachably and sealingly joined to one another by gluing or thermal welding and thus form the second housing part 6 of the device 2 forming container 8.
- a grippable web or grip region 26 is protected from contamination by body fluid accommodated inside the container 8;
- a privacy screen is thereby formed which, viewed from above, partially or preferably completely overhangs the area of the engagement opening 24.
- FIG. 7a shows the arrangement of the filter 100 in the container 8. It can be seen that the filter 100 in an axial direction 102, which also corresponds to the joining direction of the half-shell parts 20, 22 and perpendicular to a dividing plane 104 between the half-shell parts 20, 22, between the sealing element 54 and an inner region 106 of the half-shell part 22 is arranged.
- This inner region 106 is preferably formed by preferably a plurality of ribs 108, which are also particularly clearly visible in FIG. They advantageously also extend in the axial direction 102 and preferably additionally radially to the axial direction 102.
- the filter 100 has, for example, a cup-shaped form, wherein it is supported axially against the ribs 108 with the outside of the pot bottom 110.
- the sealing member 54 is formed of an elastically yielding material. It is arranged in a through-opening 112 in a wall 114 of the first half-shell part 20 of the container 8, preferably in that it is injection-molded directly there.
- the sealing element 54 is preferably formed concentrically and comprises a passage opening 115 and therein a step 116, against which the filter 100 abuts in the axial direction 102. In this case, the sealing element 54 is slightly deformed, whereby an acting in the axial direction 102 clamping force results, which keeps the filter 100 in its intended mounting position.
- the sealing element 54 comprises a tubular projection 118 protruding into the interior of the container 8, in which the filter 100 engages axially.
- the inner diameter of the tubular extension 118 is matched to the outer circumference of the filter 100 in such a way that it is fixed in a clamping and frictional engagement therein, which facilitates the joining together of the half-shell parts 20, 24.
- the sealing element 54 comprises a tubular extension 120 projecting from the container 8 in the direction of the first housing part 4, by means of which a flow connection to the negative pressure generating device can be produced in the first housing part 4.
- the tubular extension 120 can automatically be applied sealingly against a cone-shaped approach, for example, and forming a flow connection when the container 8 is brought into its intended mounting position on the first housing part 4.
- FIG. 7b shows a sectional view corresponding to FIG. 7a, but with an opposite viewing direction through the further sealing element 56, which is formed as shown in FIGS. 4b, c.
- the sealing element 54 Like the sealing element 54, it has a tubular extension 122, 124. Its passage 52 opens into the above-mentioned chamber 48, which is sealed relative to the rest of the interior of the container 8 and communicates via the connecting piece 12 ( Figure 2) with a rinsing or measuring line, not shown.
- Both sealing elements 54, 56 are preferably produced in the same injection molding process and molded directly onto the first half-shell part 20. In order to have to provide only a bleed in an injection mold to be used for this purpose, the two sealing elements 54, 56 are connected via a common filling section 126, which is therefore filled with elastomeric material (see Figure 4).
