Definitions

• 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.
• 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.
• the object of the invention to meet these draw-backs of .
• the known ventilation devices 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.
• valve housing 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.
• the valve housing When manufacturing the. valve, body, -according to claim 3, this, too, -can be made of a suitable synthetic and in one piece.'
• 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.
• 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.
• valve housing 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.
• a valve housing Inside the housing :there 'is. an annular chamber..5 y in. -which the- valve, bo y ' . 7, 3 is placed.
• a. folded 'edge ' 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 £ ⁇ ?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.
• 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.
• 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.
