Description

The invention relates to an object for preventing Stool incontinence.  

There are many diseases in which due to a Schwa che of the Sphincter Ani more fluid and advanced Stage even firm stool can no longer be held.

The weakness of the Sphincter Ani is often exacerbated by a Schä damage and / or malformation of the anorectal region and / or of the spinal cord, such as spina bi fida. Stool incontinence also occurs with disorders of the Central nervous system and injuries to the anal canal on and May also have extensive fistulas after surgical treatments and hemorrhoids and after rectal resection.

A cure or surgical corrective treatment Stool incontinence is usually very difficult and in many Cases not possible. With conservative therapy who a special diet and training of Sphincter Ani applied, but contribute little improvement gene.

The patient is therefore forced to permanently insert an insert carry. This will usually be a diaper or a tampon his.

Because the diaper with wet faeces after a certain Soaked for a long time, it can damage the skin unless it is changed in time.

There is also a risk, particularly in the urogenital area of coli infections from a wetted diaper.

Uncontrollable odor formation can also occur arise that both the patient and him the other way around people is uncomfortable. Because a timely diaper  change is not possible everywhere, this can lead to a psy chological uncertainty of the patient.

The introduction of a tampon offers versus a diaper not a decisive advantage since he also described the ben has disadvantages.

The introduction of a tampon, which is available in different size does not lead to a sufficiently safe Closure of the intestinal exit because of the pressure created in the intestine the tampon unintentionally due to the weakness of the sphincter ani can push outwards and often laterally throughout is. Unfortunately, the patient must therefore additionally wear a diaper.

If the tampon has strong sealing properties an oversized tampon must be inserted, so that it is disadvantageous to pressure points, skin irritation, Overstretching and inflammation can occur.

Incontinence is common among older people and people prevented the diaper or tampon from being affected can change independently and the help of nursing staff have to take. A timely diaper change is therefore difficult and for this reason the above be Written problem by wearing wet diapers reinforced even further.

The present invention is therefore based on the object to develop an object through which the intestinal exit with stool incontinence simple and sufficiently safe on one pleasant manner for the patient between the times of Bowel emptying is closable so that it does not become one  unwanted discharge of solid or liquid faeces com men can.

The object is achieved by an anal catheter resolved to prevent stool incontinence, the most free Body-facing end of a supply line an acti fourable balloon which has the tip area of the feed supply line, fixed to the supply line, completely surrounds and communicates with a lumen, the ver at the end facing away from the body in this area lockable supply line merges into one approach the means for activating the balloon can be connected, with an annular pressure-stable at the feed line tion provided body, which is below the top Reichs connects to the balloon and the supply line in radially thickened this area.

The anal catheter according to the invention has the advantage that it is in Clinic and practice for doctors and nursing staff simply too handle and more comfortable for the patient than a diaper or is a tampon.

The anal catheter according to the invention can limp with one Balloon inserted into the anus into the rectum will. After activation, the balloon inflates, the anal catheter touches the outer skin of the balloon the inner wall of the intestine and closes the intestinal exit. The creation of the outer skin of the balloon is still done by the Pressurization from digested food (feces and liquids strength). The balloon takes over more advantageously a dynamic sealing function.

Furthermore, the balloon of the anal catheter is advantageous  held gently and without irritation in the intestine.

Through the ring-shaped body, which is located at the top connects richly and the feed line is thickened the intestinal exit additionally against an exit of Moisture and solid feces secured. The ring-shaped Body forms the dynamic seal through the balloon followed by a static seal. The balloon can also slightly spaced from the annular body his.

The anal catheter according to the invention thereby has a dop Protected to prevent stool incontinence.

To empty the intestine, the balloon is fed over the line emptied again, so that the anal catheter out the rectum can be removed.

In a particularly preferred embodiment of the present The present invention is the body attached to the balloon then formed from an absorbent non-woven material.

This has the advantage of moisturizing through the body can be taken, and the static seal if possible can be done optimally.

In a further embodiment of the invention alkatheters is the ring-shaped body made of an inflatable ba ren fixation balloon formed.

This has the advantage that the annular body in its Size can be varied. The fixation balloon can be targeted be inflated so strongly that it is safely on the anus of the pati  duck rests without pressure points and other loads of the patient.

In turn, on the outer contour of the fixation balloon absorbent fleece material can be attached. The fleece mat rial can be firmly connected to the fixation balloon or also interchangeable.

In a further development of the embodiment with a Fixation balloon is attached to the fixation balloon radially bores aligned with a lumen of the delivery line in connection with the feed line.

The fixation balloon can advantageously be used simultaneously with the balloon surrounding the tip of the anal catheter be fourth. The fixation balloon therefore exercises a fixie function or an abutment for the balloon. about the size of the holes over which the balloon or fixie balloon gas is supplied, can be set that the balloon first develops its full size. The fixie Balloons form a little slower and fixes them Location of the balloon.

In another embodiment of the invention The fixation balloon stands with an activation line is connected.

This has the further advantage that inflating balloons and the fixation balloon performed independently can be. The fixation function and the abutment radio tion of the fixation balloon can therefore be controlled even better be lated.  

The sealing effect of the anal catheter according to the invention is further improved when between balloon and ring shaped body a tampon ring is attached. The tampon ring can be fixed to the anal catheter or hygienic African reasons there be exchangeably attached.

If the body has a truncated cone-like outer contour, which tapers towards the tip of the supply line, can be the body is light and gentle on the patient de way in the anus to the rectum (rectum) introduce.

In a further embodiment of the invention alkatheter is the body with the supply line ver stable bound.

The connection can by an adhesive connection, a Ver weld or come about in some other way.

The positionally stable connection has the further advantage that the Body such an abutment for the connected to the supply line a balloon that can be activated. Through the interaction of balloon and annular body is the invention Anal catheter to prevent stool incontinence especially well fixed. Because of this, the effect of dyna mix and the static seal increased even further.

In a particularly preferred embodiment, the Kör per via a plate formed on the feed line fixed in the axial direction.

This has the great advantage that the annular body not with the supply line for a positionally stable fixie  tion must be firmly connected. The body supports itself a contact surface on the plate and is between the activatable balloon and the plate jammed.

The ring-shaped body made of an absorbent material can in this embodiment, therefore, after an bowel movement quickly and easily removed and replaced with a new one be exchanged. This will handle the fiction contemporary anal catheter to prevent stool incontinence facilitated.

It also reduces the cost per application because it doesn't the entire anal catheter must be replaced.

If the plate is made of a stable and flexible art fabric is made, it can easily adapt to the Fit body contours in the area of the intestinal exit.

The plate also has the further advantage that it possible insertion length of the anal catheter limited. An uncompromising intentional injury to the rectum is thus significantly reduced graces.

This is advantageously reinforced by the fact that Plate circular or oval and with respect to the tips area is at least partially made concave.

Advantageously, the plate can also be made from a dimensionally stable len thin plastic film. Then she instructs weight and lies easily on the body contour in the Anal area.

The balloon is at the top when not activated  at. So that the balloon after an introduction to the intestine can be activated even if the tip is strong is pressurized, the tip area is above radial bores directed towards a lumen of the supply line and / or via an open tip with the balloon in ver binding.

If the anal catheter is designed so that on the body turned the end of the supply line closing means for the Lu men are provided, the balloon can be activated and then kept in the activated state.

It is advantageous in the case of the anal cathode according to the invention ter as activating agent of the balloon is a gas or gas mix, such as B. air, or a liquid, such as. B. Koch saline solution, provided.

This has the advantage that the balloon is easy to activate is. By a liquid in the balloon, which is back and forth when the patient moves in addition, the Sphincter Ani are stimulated and stimulated.

The anal catheter according to the invention is particularly easy attach to the patient's body when the delivery line immediately after exiting the body in the direction body angled end is angled.

Because of the corrugated and / or with in the activated state The balloon can be provided with longitudinal ribs on the outer contour of the balloon lon particularly securely fixed at the anal exit, because he can also squeeze into skin folds and then ver liable to lie.  

It is also particularly preferred that the anal catheter be made of sterilizable elastic and flexible materials is finished.

This has the advantage that the same anal catheter under one The maintenance of specified hygiene measures is used several times that can.

It is also advantageous that the balloon on the outer skin is coated or coatable with a lubricant, so that the anal catheter gently and gently into the anus is feasible.

In a further embodiment are on the feeder line fasteners, such as tapes and / or adhesive strips provided that allow the feed line can be easily and quickly attached to the patient's body can.

It is also beneficial if the anal catheter is a single-use instrument is producible. This can occur in certain use cases be partaking if the anal catheter is not reused can be. In these cases it can be easily and knocked out manufacture inexpensively.

The anal catheter according to the invention is a safe anal anal ponade and can thus be used as a much improved aid viewed as a means of preventing stool incontinence the. With the anal instrument described as Ballonka is formed, is a secure closure of the Sphincter Ani possible over defined periods. Under Ver is the new multi-closing anal tamponade an uncontrolled discharge of stool through the sphincter  Ani almost impossible.
