BRIEF SUMMARY
BACKGROUND OF THE INVENTION

This invention relates to a fixing device for a stomy bag (enterostomy) intended to improve the situation for stomy-operated persons.
The fixing means for stomy bags found on the market have great disadvantages. Thus, fixing devices or attaching plates for stomy bags are used, which plates must be attached to the skin by means of adhesive ties. Moreover, self-adhering bags without an attaching plate occur as well as plates attached to belts which must also be sealed against the carrier's skin by means of adhesive ties. These means of attachment have such after-effects that wounds arise on the skin caused by allergy or mechanical irritation. Leakage of intestinal contents will often occur and become a nuisance to the patient.
As a rule, the connection between the stomy bag and the attaching plate or attaching means is so embodied that a great force is needed for the connection of the bag to the attaching means in order to obtain the best possible sealing. Further, the commonly used sealing groove of the connection must be carefully cleaned to obtain the best possible sealing at the time of exchange of bags. There has been no possibility of sealing the intenstinal orifice at removed stomy bag.


SUMMARY OF THE INVENTION

It is the object of this invention to eliminate the above-mentioned disadvantages by providing, in combination, the features of the invention defined in the appended claims.


BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be described in greater detail in the form of an example with reference to the drawings, in which
FIG. 1 is a lateral section of an embodiment of the invention,
FIG. 2 is a top plan view of the device according to FIG. 1,
FIG. 3 is a section of the device according to the invention shown in FIGS. 1 and 2 and inserted in the intestinal orifice,
FIG. 4 is a section of the device fixed in the intestinal orifice and with an applied stomy bag (only a part thereof is shown).
FIG. 5 is a section of the device secured in position in the intestinal orifice and with activated cut-off valve,
FIG. 6 is a schematic cross-section of the function of the cut-off device,
FIGS. 7, 8 and 9 show schematically the function of a valve included in the device,
FIG. 10 is a top plan view and
FIG. 11 a lateral view of a cover which can be applied to the device instead of the stomy bag.


DETAILED DESCRIPTION

In principle, the fixing device of the invention can be said to consist of two parts, namely a substantially tubular body 1 and a counter-holding ring 2.
The counter-holding ring 2 shown in FIGS. 3-5 can, for instance, consist of a plastic or similar material. The ring 2 is operated under the carrier's outer skin 33 when the intestine 4 is sewn onto the outer skin.
The tubular body 1 has a diameter permitting insertion of the body through the counter-holding ring to a position shown in FIG. 3 where a flange 5 of the body 1 will get in contact with the outer skin 3. As is apparent from the figures, the intestine 4 will be placed around the inwardly, directed tubular body 1 which, therefore, has well-rounded edges, like, of course, the counter-holding ring 2. The tubular body 1 is provided with an outer peripheral portion 6 of an elastically ductile material with an annular cavity 7 lying inside thereof. This cavity is, via a channel 8 and a nonreturn valve 9, associated with the outside of the flange 5, where the channel 8 ends in a socket-like opening 10.
The channel in the tubular body 1 has an enlarged diameter along a portion 11. On one side of the channel wall and along said portion 11 a gas-tight bladder 12 is arranged, the interior 13 of which is associated with a socket-like opening 16 on the outside of the flange 5 via a channel 14 and a nonreturn valve 15.
When the fixing device or the tubular body 1 has been positioned with the flange 5 in contact with the carrier's skin, as is apparent from FIG. 3, the annular cavity 7 is set under pressure, whereby the peripheral portion 6, which will be inside the counter-holding ring 2 in this position, will ex
