Hollister Moderma Flex Convex One-Piece Closed Colostomy Pouch – Maxi, Beige, 15–51mm – Box of 30 (Ref: 22801)

Hollister Moderma Flex 22801 is a one-piece closed convex colostomy pouch designed for people with formed or relatively predictable stoma output who require additional convex support around the stoma.

This Maxi Beige pouch has an integral convex skin barrier and a generous 15–51mm cut-to-fit opening, allowing the aperture to be individually prepared to fit the size and shape of the stoma.

The convex profile is designed to provide controlled support around the stoma and can help improve the seal where the stoma is flush, recessed or positioned within an inward or uneven peristomal area.

Moderma Flex 22801 also incorporates an integrated filter, anatomical pouch shape and soft comfort backing on both sides for discreet everyday wear.

One-piece closed appliance

Moderma Flex 22801 is a one-piece system.

The pouch and convex adhesive skin barrier are permanently connected.

There is:

• No separate baseplate

• No mechanical coupling

• No separate pouch attachment

When the pouch requires changing, the complete appliance is removed and replaced.

This provides a relatively simple, low-profile alternative to a two-piece system.

Closed colostomy pouch

Ref 22801 is a closed pouch rather than a drainable pouch.

It has no opening at the bottom for emptying.

Closed pouches are generally best suited to colostomy output that is:

• Formed

• Semi-formed

• Less frequent

• Relatively predictable

When sufficient output has collected, the complete pouch is removed and replaced with a new one.

For frequent liquid output, a drainable appliance may generally be more practical.

Integral convexity

The defining feature of Ref 22801 is its integral convex skin barrier.

Convex appliances curve towards the body and apply controlled support to the area immediately surrounding the stoma.

This can help:

• Encourage a flush or recessed stoma to protrude more effectively into the pouch

• Improve contact between the adhesive and skin

• Reduce gaps underneath the barrier

• Direct stoma output into the pouch

• Reduce the likelihood of output reaching exposed peristomal skin

• Improve security where a flat appliance has difficulty maintaining a seal

Convexity may be useful where the stoma is:

• Flush with the skin

• Slightly recessed

• Located in a shallow dip

• Surrounded by uneven skin

• Associated with recurrent leakage when using a flat appliance

Convexity should always be selected according to the individual stoma and surrounding body profile.

SoftFlex™ skin barrier

Moderma Flex 22801 uses Hollister's SoftFlex™ hydrocolloid skin barrier.

SoftFlex is a standard-wear adhesive designed to provide secure adhesion while remaining relatively gentle to the skin.

This is particularly relevant with a closed pouch because the complete adhesive is removed whenever the appliance is changed.

The barrier is designed to:

• Adhere securely around the stoma

• Remain flexible during movement

• Provide comfortable skin contact

• Support frequent pouch changes

• Help protect the peristomal skin from stoma output

Correct sizing of the stoma opening remains essential.

15–51mm cut-to-fit opening

Reference 22801 has a 15–51mm cut-to-fit opening.

The barrier can be cut according to the measured size and shape of the individual stoma, within the manufacturer's stated range.

A cut-to-fit pouch may be particularly useful where:

• The stoma does not correspond to a standard pre-cut diameter

• The stoma has an irregular shape

• Stoma dimensions are changing

• A more individually shaped opening is required

Do not enlarge the opening beyond the manufacturer's stated maximum of 51mm.

Choosing the correct opening

Measure the stoma carefully using an appropriate stoma measuring guide.

The finished opening should:

• Fit closely around the stoma

• Avoid rubbing against the stoma

• Avoid constricting it

• Minimise exposed peristomal skin

• Follow the actual shape of the stoma where required

An opening that is too large can leave surrounding skin exposed to stoma output.

This may contribute to:

• Redness

• Soreness

• Skin irritation

• Moisture damage

• Reduced adhesive performance

• Leakage

An opening that is too small may rub against or constrict the stoma.

Maxi pouch

Ref 22801 is a Maxi pouch.

The larger pouch size provides increased collection capacity compared with smaller Moderma Flex options.

Manufacturer product data identifies this configuration as having approximately 700ml nominal capacity.

Maxi may be preferable where:

• Greater collection capacity is desired

• Output volume is higher

• A larger closed pouch is more convenient

• Less frequent pouch changes are preferred

Actual usable capacity can vary depending on fitting and how full the pouch is allowed to become.

The pouch should be changed before it becomes excessively full or heavy.

Integrated AF300™ filter

Moderma Flex Convex incorporates Hollister's AF300™ filter.

The filter is designed to allow intestinal gas to leave the pouch gradually while helping neutralise odour.

This can help:

• Reduce pouch ballooning

• Manage intestinal gas

• Control odour

• Maintain a flatter pouch profile

• Improve discretion beneath clothing

The filter is integrated into the pouch and does not require the user to puncture the pouch.

Do not modify or puncture the filter.

Anatomical pouch shape

The NHS Drug Tariff describes the Moderma Flex Convex range as having an anatomical shape.

The shaped pouch is designed to sit naturally against the abdomen and provide a discreet profile beneath clothing.

Together with the Maxi format and comfort backing, this supports comfortable everyday wear.

Beige opaque pouch

Ref 22801 is Beige / opaque.

The opaque pouch conceals the contents during normal use, providing greater discretion than a transparent version.

The corresponding transparent 15–51mm product in the range is Ref 22901.

Comfort backing on both sides

The Beige 22801 pouch has comfort backing on both sides.

The soft covering helps:

• Improve comfort against the body

• Reduce direct contact between pouch film and skin

• Improve discretion

• Provide a softer textile-like feel

• Reduce the medical appearance of the appliance

Odour-barrier pouch film

Moderma Flex uses odour-barrier pouch film designed to contain stoma output and reduce transmission of odour through the pouch material.

Together with the integrated filter, this provides two complementary forms of odour management:

• Pouch film contains the collected output

• Filter manages gas leaving the pouch

Convexity and opening size are separate considerations

Selecting the correct 15–51mm opening size does not automatically mean that convexity is appropriate.

The appliance profile should also be selected according to:

• Stoma protrusion

• Whether the stoma sits above, level with or below the skin

• Peristomal dips

• Folds and creases

• Abdominal contour

• Previous leakage

• Skin condition

• Tolerance of pressure around the stoma

A Stoma Care Nurse can assess whether convexity and the degree of support provided by the appliance are appropriate.

Applying the pouch:

Wash and dry your hands.

Measure the stoma carefully.

Mark the required opening on the barrier.

Cut the opening to the measured size and shape of the stoma.

Do not cut beyond 51mm.

Gently remove the existing appliance while supporting the surrounding skin.

Clean the peristomal skin according to the normal stoma-care routine.

Ensure the skin is clean and appropriately dry.

Remove the protective backing from the adhesive.

Centre the opening carefully around the stoma.

Apply the convex barrier to the skin.

Press gently but firmly around the stoma to establish secure contact.

Smooth the adhesive outward.

Check for:

• Gaps

• Creases

• Folds

• Areas where the adhesive is not in full contact with the skin

Apply gentle hand pressure to help establish the seal.

Always follow Hollister's instructions for use.

Changing the pouch:

Because Ref 22801 is a closed one-piece appliance, the entire pouch and adhesive barrier are removed together.

Change the pouch when required rather than attempting to empty it.

To remove:

• Wash and dry your hands

• Gently lift one edge of the adhesive

• Support the surrounding skin

• Slowly peel the barrier away

• Avoid rapidly pulling the adhesive from the skin

• Dispose of the used pouch appropriately

• Clean and inspect the peristomal skin

• Apply a replacement pouch

Check the skin regularly

The skin immediately surrounding the stoma should normally remain similar in appearance to the surrounding abdominal skin.

Check for:

• Redness

• Soreness

• Moisture damage

• Broken skin

• Persistent pressure marks

• Leakage beneath the adhesive

Because this is a convex appliance, persistent pain or pressure-related skin changes should not be ignored.

Repeated leakage may indicate that:

• The opening is too large

• The opening has been cut incorrectly

• The stoma size has changed

• The convex profile is inappropriate

• Additional stoma-care accessories are required

• The surrounding body profile has changed

A Stoma Care Nurse should assess persistent problems.
