Abstract
A surgical drainage bag 1 has two walls of a plastics material which is impermeable to liquids and gases. The said walls are secured together at their peripheral edges. An inlet opening 3 extends through a rear wall 2 of the bag. A non-occlusive fixing flange 5 of a micro-porous material is disposed to the rear of the rear wall of the bag and has an opening surrounding the inlet opening 3 in the rear wall of the bag. A layer of a non-occlusive adhesive is provided on the rear surface of fixing flange 5. A mounting ring 8 of a material which is impervious to liquids and gases surrounds the inlet opening 3 in the rear wall 2 of the bag and has an area sealed to the rear wall of the bag and another area overlapping a portion of the rear surface of the fixing flange. The fixing flange 5 is secured between the mounting ring 5 and the rear wall 2 of the bag. A layer 9 capable of adhering to the skin of a patient is secured to the rear wall of the mounting ring 8. <IMAGE>
Description
SPECIFICATION
Surgical drainage bags
This invention relates to surgical drainage bags such as are commonly used by ileostomy or colostomy patients. Such bags are commonly known as "ostomy" bags and they will be so described herein.
Ostomy bags are commonly made oftwo sheets of flexible plastics material arranged in face contact and welded or otherwise sealed at the edges. The plastics material is impermeable to liquids and gases. When the two sheets are sealed together, there is provided a bag with two walls one of which will, in use, contact the body ofthe patient. This wall will herein be referred to as the rearwall. Such a bag has an inlet in the rearwall capable of receiving the stoma of a patient so that the contents of the intestine ofthe patient can pass from the stoma into the bag. The bag is commonly surrounded by a fixing ring, usually called a fixing flange, which is secured to the bag and normally carries an adhesive by which the bag can be secured to the skin of the patient.The bag may be further secured by a belt or the like passed round the body ofthe patient and fixed to the bag in any suitable way.
A disadvantage of such bags as commonly in use at thepresenttime is that the fixing flange and adhesive are occlusive and some patients have a skin which is sufficiently sensitive to be undesirably affected by such an occlusive covering. An object ofthe present invention isto provide a bag which will not have this disadvantage.
Accordingly, the present invention provides a surgical drainage bag which has two walls of a plastics material which is impermeable to liquids and gases, the said walls being secured together attheir peripheral edges, and an inlet opening through a rear wall ofthe bag wherein a non-occlusive fixing flange of a microporous material is disposed to the rear of the rearwall of the bag and has an opening surrounding the said inlet opening in the rearwall of the bag; a layer of a non-occlusive adhesive being provided on the rear surface of the fixing flange; wherein a mounting ring of a material which is impervious to liquids and gases surrounds the said inlet opening in the rearwall ofthe bag and has an area sealed to the rearwall of the bag and another area overlapping a portion of the rear surface of the fixing flange,the said fixing flange being secured between the mounting ring and the rear wall of the bag; and wherein a layer capable of adhering to the skin of a patient is secured to the rearwall ofthe mounting ring.
The material of the bag and ofthe mounting ring is preferably polyvinyldichloride (PVDC). The adhesive layer is preferably of a hydrophilic polymeric material.
The bag of this invention is more comfortable to wearthan most bags at present in use and has a greater security against leakage of the contents of the bag.
The accompanying drawings schematically illustrate some preferred embodiments of the invention.
In the drawings;
Figure 1 is a schematic sectional view of a bag constructed according to the invention fixed to the body of a patient,
Figure 2 is an exploded sectional view of part of the bag, and
Figure 3 is an exploded sectional view of a modification.
in the illustrated embodiment of the invention, an ostomy bag 1 is made of a plastics material which is impermeable to gases and liquids, preferably PVDC.
The rearwall 2 ofthe bag has an inlet opening 3 through which the stoma 4 of a patient can pass.
A fixing ring or flange 5 is located adjacentto the rearwall 2 of the bag. This flange 5 has an opening 6 which is at least as large as the opening 3 in the bag, but may be larger as shown in Figures 2 and 3. This fixing flange 5 is made of a non-occlusive, microporous material which is preferably a spun-bonded polymer, tissue or perforated plastics material having non-occlusive adhesive on its rear surface. A layer 7 of a release material may be attached to the adhesive rear surface of the fixing flange 5. The fixing flange 5 is located around the inlet opening 3 in the rearwall 2 of the bag by means of a mounting ring 8 of a material which is impermeable to liquids and gases, and which is preferably the same material as the material ofthe bag 1.The mounting ring also has an area which overlaps the rear surface of the fixing ring which is therefore positioned and secured between the mounting ring and the rearwall of the bag. The mounting ring 8 has an area which is secured to the rearwall ofthe bag preferably by radio frequency welding. The extent of the weld is indicated bythe broken lines in Figures 2 and 3.
In the embodiment illustrated in Figure 2 the weld between the mounting ring 8 and the rearwall ofthe bag 2 overlaps the area ofthefixing flange 5, overlapped bythe mounting ring, whereas in the embodiment of Figure 3 the opening 6 in the fixing flange 5 is of a largersize so that there is no overlap between the weld and the flange 5.
In both embodiments, since the mounting ring 8 is of material impermeabletoliquidsandgasesand since it is secured to the rearwall 2 of the bag which is also made of a material that is impermeable to liquids and gases, there is no leakageofthecontentsofthe bag through to the micro-porous fixing flange 5.
The mounting ring 8 also provides a platform for a layer 9 of material intended to seal and securethe bag to the body of a patient, and also to protect the skin around the stoma. The layer 9 is secured to the mounting ring 8 by means of an adhesive 10, which is attached to the layer of plastics film 11. A layer 12 of release paper is attached to the rear surface of the layer 9.
The layer 9 may be of any suitable material capable of being secured on one side to the mounting ring 8 and on the other side capable of adhering to the body of a patient. The layer 9 is preferably, but not essentially, of the hydrophilic polymeric skin-care material known underthetrade mark SEEL-A-PEEL and described in the published British Patent Specification No. 2046764A.
As will be clearly seen in the drawings, an opening 13 in the layer 9 is smallerthan the openings 14, 6 and 3 in the mounting ring, fixing flange and rear wall of the bag respectively. This enables the material of the layer9 to be "formed-up" around the stoma 4 of the patient as shown in Figure 1 and in addition to layer 9 maybe cut so as to fit closely around an irregularly shaped stoma. This improves the seal and reduces the risk of leakage. The plastics film layer 11 is laminated into the material of the layer 9. This plastics film layer prevents the layer9from sticking to the frontwall ofthe bag.
As will be clearly seen in Figure 2 of the drawings, the opening 6 in the fixing flange 5 is largerthan the opening 3 in the rearwall ofthe bag. The opening 14 in the mounting ring 8 is smallerthan the opening 6.
The opening 13 in the layer9 is smaller than any of the other openings.
The use of the non-occlusive micro-porous mate rial forthefixing flange 5 makesthe device more comfortable to wearthan is possible with most known ostomy devices. In addition, the flange 5 assists in securing the device to the bodyofthe patient and in preventing the outside edges of the layer9from lifting asa result of catching on clothing.
