Abstract

An ostomy bag for the collection of drainage substances from an opening in the abdomen, caused by a surgical operation, may be supplied with an excess-pressure valve, which consists of a valve housing (3) fastened to the wall of the bag (1) and with an inlet opening (4) for the gases from the interior of the bag as well as a vent hole (6). Inside the housing there is a vent seat (10) running round the opening (4). Against this seat (10) a disc-shaped vent body (8) is continuously pressed by means of a number of elastic flaps (7) to allow an outlet through the vent of any excess-pressure in the bag. In this way the pressure in the bag can be regulated, and a suitable back-pressure for the intestinal function achieved, securing a closing of the outlet opening when the valve is in its closed position. This means that no leaking out of fluid can take place. In order to deodorize the gases a carbon filter can be mounted round the outlet opening, which filter the gases must pass.

Description

VENTILATION DEVICE FOR AN OSTOMY BAG
The invention relates to a ventilation device for. be¬ ing mounted on a fluid tight bag with a vent hole in the wall of the bag for the outflow of gases from the bag and with an inlet opening in the wall of the bag that can. be placed' opposite an opening in the abdomen caused by a surgical operation, and. fastened herme¬ tically to the skin encircling said opening.
By certain abdominal operations the intestinal system has to be drained through an opening in the wall of the abdomen. This causes that the patient has to make use of a bag for the collection of the drainage substances in the shape of liquid-, solid, and gases. The bag is tightly connected to the opening of the abdomen to permit a continuous function. Bags of this kind is often supplied with a ventilation device in the collection bag so that an outlet of the gases can take place. Without this ventilation device an inflation of the bag would take place, causing the bag being pressed away from the skin.to .the..conside¬ rable inconvenience of the user.
Hitherto known ventilations devices consist of a carbon filter, which is mounted in the wall of the bag, forcing the gases through the filter before leav¬ ing the bag. In this way the gases are deodorized to eliminate any outlet of bad air.
These filters, however, do not always function satis¬ factorily, as they do not work pressure regulating. This means that no 'suitable pressure can be built up in the. bag that can regulate the outflow from the intestinal system. Besides the very filter unit is exposed to being soaked, as fluid from the bag can leak "out through the filter, e.g.' if the patient places himself in a position where the filter is lower than the. fluid level in the. bag. This causes considerable inconvenience to the user.
It is the object of the invention to meet these draw-backs of .the known ventilation devices, and this is achieved, when the device comprises a valve body, which abuts elasticallv on an annular valve seat that runs round the the vent hole in the wall of .the bag. This device acts as an excess-pressure valve, as a regulation of the pressure in the bag can take place, when choosing a 'suitable elasticity, so that a suitable back-pressure can be built up, before the valve opens and the gases thus are releas¬ ed.
This has a regulating effect on the intestinal system and gives greater degree of physical well-being to the patient, who in this way gets a function of drai¬ nage that on the whole corresponds to what is normal. Further the valve -secures that no fluid leaks out f oπϊ the bag, as a passage through the vent hole will be effectively closed, when the valve is in its closed position. This will be the case most of the time, for which reason the risk of leaking out of fluid will be reduced accordingly.
When producing the device as mentioned in claim 2, the valve housing can be formed in a suitable synthe¬ tic without the housing being inconveniently large. When manufacturing the. valve, body, -according to claim 3, this, too, -can be made of a suitable synthetic and in one piece.'
Finally, it is appropriate to supply the. vent hole with a suitable carbon filter in order to eliminate the 'outlet of .bad air, as mentioned in claim 4.
In the following" he invention will be further descri- bed with reference to the drawing,' where
Fig. 1 shows the ventilation device mounted on the wall 'of a bag, seen from the outside, Fig. 2 shows the very valve body,
Fig. 3 shows the device with the valve in its closed position, seen in the direction III-III in Fig. 2, and Fig. 4 shows the device with the valve in its open position.
In Fig. 1 an example of an embodiment of the ventila¬ tion device is shown, this being mounted on the wall of the bag 1. The .device comprises a thin baseplate 2, which is supplied with a vent hole 4 in the middle, also cmp Figs' 3 and 4. The wall of the bag is perfora¬ ted in this place or supplied with one or more ope¬ nings to create a passage for the gases from the in- teriour of the bag out through the hole 4.
On the baseplate there is a valve housing, which in the shown example consists of a round housing 3 which is supplied with a valve seat 10 round the inner vent hole 4, this valve seat encircling the hole 4. Inside the housing :there 'is. an annular chamber..5 y in. -which the- valve, bo y' .7, 3 is placed. At the Outside the housin "is supplied with a. folded 'edge', which makes the outer vent hole 6.
The. valve, body itself is shown in Fig. 2. It is made of e.g. soft elastic nylon and disc-shaped, the inte- riour of which, orms the valve, body . '8. Along- the cir¬ cumference a number of .elastic, flaps are formed ele- vated £ι?om the. valve body, as shown in Figs 3 and 4. Between the valve body 8 and the flaps 7 there are some slots 9, through which the gases can pass.
The valve body can be edged into the annular chamber of the housing,' and it will here assume the position of Fig. 3 with the elastic flaps 7 abutting the edge, and with the valve body abutting the. valve - seat 10 so that no passage of the gases from the in- teriour of the bag and outwards can take place.
When the air pressure in the bag rises it will cause the valve body to rise from the seat by a predetermined size of the pressure, and take the open position of Fig. 4. Thus the gases will escape, and when the air pressure falls to a certain level the flaps will again close for the passing through.
When placing a not shown carbon filter in the vent hole 6 the gases can be deodorized in order to eli i- nate the inconvenience of bad air slipping out.
Instead of the described and shown housing one can imagine a housing, where the outer, vent hole is pla¬ ced along the outer edge of the housing. The gases will in this way. be led out along, the circumference f .the housing,- and if an annular carbon filter is placed, round the housing, this will give' a possibi¬ lity for an effective deodorizing, as- the gases can pass a suitable piece of the filter, before, being led out. The annular breadth of .the. filter can be of any sufficient size, and the filt'er may be of a kind that can be closed at the sides so that the. gases can only pass radially through the filter.
