Description

SYSTEM FOR intermittent self

The invention relates to a scheme for intermittent self (ISK), comprising a catheter and an outer package for sterile storage of the catheter, the catheter having a tube having at least one opening at the proximal end and a connector at the distal end.

To cope with the incontinence of male persons, in particular in spinal cord injury (ISK) is applied, inter alia, the so-called intermittent autocatheterism, after which the incontinent person catheterized four to six times a day itself. To remain continent between the Katheterisierungsphasen, a drug is prescribed usually by the attending physician, which deactivates the bladder or immobilize. Especially for the so-called autocatheterism Catheter made available to date, which must be disposed of after a single use. Assuming that, particularly with paraplegia six times is catheterized day, such a person needs about 40 catheter including accessories per week. Especially when you travel, this requires taking along a quite considerable volume of material on the one hand and caused not inconsiderable costs.

If you wanted to make a reusable catheter for private treatment available, you would have to ensure that the catheter before the application is sterile. Numerous methods of sterilization are eliminated for personal use from the outset, at least if you want to keep the size of the necessary equipment as low as possible. In addition, there is always the risk of insufficient sterilization, so that upon application of a reusable catheter germs, bacteria, etc. can be dragged into the bladder. Life-threatening infections can be the result.

is merely exemplary referenced 0 384476 B1 with respect to the previously known single catheter to the EP. The object of the present invention is based is to provide a system for intermittent self, which also allows for in the private, personal space, the multiple use of a catheter in einfachster construction and secure handling.

The above object is achieved by a system for the intermittent self having the features of claim 1. the generic type system then being characterized in that the outer package is formed as both sides closable, hose-like shell for receiving and / or for passing a disinfecting liquid and that the sheath to release the catheter along the catheter from the proximal end toward the distal end collapsible or foldable ,

According to the invention it has been recognized that it is possible to equip the already required to provide sterile outer packaging of the catheter having a dual function, namely to the effect that one uses this outer package also for disinfection or sterilization after use of the catheter. For this purpose, the outer package is formed as a hose-like shell, which on both sides is, that can include a liquid-tight to the respective ends of the schlauchbaren sheath. Thus, the sheath not only for storage of the catheter, but also for supporting the catheter in a disinfecting liquid or disinfecting liquid for flowing through, and thus for the disinfection of the catheter can be used.

In principle, it is conceivable that it again pushes the catheter after a single use in the tubular sleeve or this inside out through the catheter. For one-sided closure of the sheath can fill a vessel to be provided disinfecting liquid in the tube-like sheath. One closes the casing on the other side, leaving the catheter with its fitting in the casing, that is either together with the disinfection liquid. Over the time course of time a reliable disinfection of the catheter takes place, it is easily possible to drain the liquid disinfectant until before the next use of the shell.

It is also possible that one leaves the disinfecting liquid for a short time together with the catheter in the sheath and the liquid drained at set exposure time. It is also conceivable to flood the sheath and the catheter with the disinfecting liquid and to direct the disinfectant fluid, preferably with a low flow rate through the sheath and the catheter therethrough so that this is already taking place, the disinfection and sterilization. Thereafter, the casing is to be closed on both sides, so that the catheter is sterilized state - possibly with residual liquid - remains in the shell.

In order to release the catheter a very special property of the sheath is required, namely in terms of their material and their elasticity or flexibility. Thus, in further accordance with the invention, the sheath to release the catheter along the catheter from the proximal end toward the distal end is collapsible or foldable. Specifically, the sheath can take in the region of the connection piece and with an open proximal end slide together toward the distal end of the catheter through the hose away or - according to the respective construction - fold. So can be introduced into the ureter at freigelegtem proximal end, the catheter and can be exposed according to the degree of insertion depending on the progress of work by pushing back the sheath. Such a procedure is far optimal, as a contamination of the catheter tube of improper handling is very largely avoided.

It should be noted that the catheter can be provided regardless of the above, with a lubricious coating. It is also possible, through pulling the catheter through a reservoir with lubricant. Any insertion of the catheter favorable technical / design measures can be implemented, and it primarily is about the germ-free provision of the catheter.

Specifically, the casing made of a preferably transparent plastic in the sense of a conventional plastic bag can be produced. Preferably, a transparent plastic is used, in order to detect the maintenance state of the catheter here. Use of such a resin to form the tubular sleeve has, since in fact be the advantage of simple construction such plastic material easily pushed together in a small space, similar to the outer packaging of a drinking tube. Thus, the proximal end of the catheter tube can be easily to the connector at the distal end exposing and can be in accordance with the application, the case back slide away in the proximal direction through the tube of the catheter end without a conditional by use of the catheter contamination to the outside of the sleeve passes.

In a further advantageous manner the sheath at the distal end is equipped with a surrounding the fitting sleeve, which is closeable towards the free end. In other words, the tubular sheath has a rigid connecting piece is in the sense of a sleeve which is adapted to secure closure as well as for handling.

Likewise, the sheath proximal end may terminate with a corresponding sleeve, which is closeable towards the free end. Thus, the tubular sheath could be provided at both ends with a sleeve which is at least designed so stiff that a cap or the like attach and set liquid-tight manner can what is possible with the tubular sleeve alone is limited.

Here it should be noted that the end sleeves are not necessarily required. In einfachster construction, it is also quite conceivable that are provided independently of the sheath terminal body for two-sided secure closure of the tube-like casing, comprising the clamp-like, planar clamping strips and accomplish by clamping the sheath a secure closure. Similar clamping bodies are known for closing plastic bags in the household sector. By opening the clamp body, the closure of the sheath can be removed. A multiple application would be to the extent feasible in einfachster construction.

Unless the tubular sleeve ends with a sleeve, it makes sense to manufacture these plastic sleeve. An injection-scale production of the sleeve would therefore be advantageous.

The provision of one or both sides sleeves to the sheath is only useful if a secure, irreversible connection between the tubular casing and the sleeve or the sleeves is guaranteed. For this purpose, it is conceivable that the tube - is shrunk literally on the sleeve - as in a so-called shrink tubing. Additionally or alternatively, the hose may be glued to the sleeves or welded. In that regard, a positive connection with adhesive support material or even a positive connection with the material diffusion between the sleeve and the sleeve is conceivable in addition to a frictional connection.

To close the sleeves, different arrangements can be made. So could the sleeves - both sides of the envelope - with a kind of grafting be lockable. In a particularly advantageous manner to close the sleeves special caps could be provided to defer to the sleeve, attach, snap or screw onto.

While in the non-positive insertion of a plug-like closure a kind can be realized in situ seal, additional sealing measures are required for provision of deferrable, attachable, snap-on or screw-on sleeves, so assigned in a further advantageous manner between the sleeve and the closure cap, the sleeve or the closure cap a seal or two seals are provided respectively. In the gasket may be, be conventional seals, but also seals similar to the internal configuration of the screw cap of a beverage bottle. Any closure sealing measures and possibilities can be combined according to the specific design of the sleeve.

With respect to a safe handling, on the one hand for transport or for storage of the catheter and on the other hand with respect to the process of disinfecting, it is of further advantage when the catheter is positioned and fixed within the sheath. For this, the formed at the distal end connector may be clamped at least slightly in the sleeve so that the connector-retaining sleeve and serves for handling the catheter situated in the casing. If the fitting with rotationally symmetrical, on all sides set in the circular cross-section configuration in the sleeve, would remain for introducing the disinfecting liquid excluding the way through the catheter tube therethrough. If one wants to sterilize the catheter on the inside and on the outside as quickly as possible flowing through the disinfecting liquid, it is especially advantageous when the disinfecting liquid can pass conduct simultaneously inside and outside the catheter. For this purpose the sleeve on the inner side could have longitudinally extending ribs spaced from the inner wall for securing the connector. In other words, while the sheath is kept exclusively on the inwardly extending ridges, so that along the circumference of an outside inflow of disinfection fluid in the area between the inner wall of the sheath and outer wall of the catheter tube is possible. The serving for fixing the connector webs hinder the inflow of disinfection fluid insignificantly.

As already stated above, the disinfecting liquid might be filled into the casing and remain for a certain contact time or until the next use of the catheter there. For safe filling or to flow through the envelope with a disinfectant directly or indirectly attachable to the sleeve disinfection container is provided, which is also part of the presently claimed system. An indirect flow connection between the disinfectant container and the envelope containing the catheter can be accomplished for example via a hose. For the reduction of the material or required of required equipment, it is also possible that the disinfection container - it can here be a plastic bag with disinfectant liquid, for example - to connect or to infect directly to the sheath, namely in the concrete to the sleeve at the distal end. From there, the disinfecting liquid can flow into the casing and through the catheter.

For safe handling If specific measures for plugging the disinfectant container can be realized to the sleeve, such as using a special coupling piece, which can be freely handled or the sleeve or the disinfectant container assigned. The coupling piece may thereby be configured such that an influx or flowing through the disinfecting liquid is possible in or through the catheter and into the area around the catheter. In this case, could be operatively connected not only to the sleeve, but also to the connector of the catheter within the sleeve and be operatively connected to the coupling piece. There are various possibilities for embodying and developing the teaching of the present invention advantageously. For this purpose, on the one hand to the claims subordinate, on the other hand refer to the following explanation of an embodiment of the invention with reference to the drawing. In connection with the explanation of the preferred embodiment of the invention with reference to the drawing, generally preferred embodiments and further developments of the teaching will also be explained in general. In the drawing

Fig. 1 is a schematic side view of an embodiment of an inventive system for the intermittent self, wherein the catheter is inserted into a closable case with both ends serving for sealing sleeves and caps for the sterile storage, and

Fig. 2 is a schematic side view of the article of FIG. 1 with the sheath or pushed back freigelegtem tube of the catheter.

Fig. 1 shows an embodiment of an inventive system for the intermittent self comprising a catheter 1, which is located with its hose 2 in an outer packaging. 3 The outer package 3 is 1. Fig for sterile storage of a catheter. 1 further shows that the tube 2 of the catheter 1 at the proximal end 4 has openings 5 ​​for the inflow of the liquid urine to be derived. At the distal end 6, a connector 7 is provided, on which one usually the catheter 1 with a collecting container, such as a bag, strömungsverbindet.

In the present invention, the outer package 3 is formed as an both sides closable, tubular sleeve 8 for receiving and / or for passing a disinfecting fluid. To enable the catheter 1, the sleeve 8 along the catheter 1 from the proximal end 4 to the distal end 6 towards collapsible or foldable. This situation, the release of the proximal end 4 and the tube 2 is indicated in Fig. 2. While Fig. 1 shows the outer package 3 and the tubular sheath 8 in the closed state, FIG. 2, the outer package 3 and Case 8 in the open state.

Thus, both the distal end 6 as well as at the proximal end 4 of the sleeve 8 comprises a sleeve 9 surrounding the connecting piece 7 at the distal end. 6 More specifically, the connection piece 7 is fixed within the sleeve 9 and clamped so that a secure handling of there is possible. For fixing or clamping of the connection piece 7, both the connector 7 of the outer side and the sleeve 9 on the inside of the clamping means may comprise, for example, there thus formed terminal bars 10 which are only indicated in FIGS..

On both sides of the hose 2 bushes 9 are provided, which are fixedly connected with the material of the hose. 2 The tube 2 is lockable on both sides on the sleeves 9, namely by means of special caps 11 on the sleeves 9 can be plugged and can be fixed using the thus formed clamping action involving a seal 12th The provision of a locking mechanism promotes the safe and thereby liquid-tight seal.

The tube 2 is made of transparent plastic, similar to a plastic bag. The sleeves 9 and the end caps 11 are also made of plastic, namely by injection molding. The catheter 1 itself is designed as a conventional catheter, with conventional disposable catheter for multiple sterilization are suitable.

Referring to Fig. 2 further is to be noted that it is not necessary and is not also useful to remove the catheter 1 in total from the sheath 8. Thus, the catheter 1 remains at least with the connecting piece 7, that is, with its distal end 6, within the envelope 8, wherein the handle via the associated the distal end 6 of the sleeve 9 is performed. Thus the whole device on the sleeve 9 at the distal end 6 is gripped and can be the casing 8 after use, slide back over the tube 2 of the catheter 1, so that approximately to the state of FIG. 1 is achieved. Thereafter, a flowing or flows through the sheath 8 can be made with disinfecting liquid, namely in accordance with the Ausführun- gene from the general part of the description. The casing 8 is closed at the sleeve 9 with the caps 11, namely until the next use.

To avoid repetition, is otherwise made to the general part of the description.

Finally, it should be noted that the above-discussed embodiment, only the exemplary discussion of the claimed teaching is used, but does not limit to the embodiment.
