Understanding the deep convex stoma bags

1.What is deep convex stoma bags?

The deep convex stoma bag is a stoma bag specially designed for patients with depressed stomas, deep skin folds, low and flat stomas, or retracted stomas. The Deep convex stoma bag exerts continuous and gentle outward pressure on the skin around the stoma through the deeper convex skin barreir. Make the stoma more prominent, thereby enhancing the sealing performance and reducing leakage.

2. the Characteristics of deep convex stoma bags

To understand deep convex stoma bags, it is also necessary to understand the composition of deep convex stoma bags. It is mainly composed of the following parts.

Deep Convexity: This is the core part of the deep convex stoma bag. The height is generally 6 to 10 mm, or even deeper. Provide stronger external thrust than Light/Shallow Convex. Make the recessed stoma more prominent, enhance sealing and reduce leakage.
Stoma bag: It is used to collect excrement discharged from the stoma. It has the functions of maintaining cleanliness and hygiene, as well as preventing leakage and odor.
Elastic Stabilizing Ring:It is used to enhance the pressure distribution on the convex surface, making the outward thrust uniform and gentle without causing indentation. Suitable for patients with loose abdomen or obesity.
Activated carbon filtration device: It can adsorb odors and prevent bag swelling and odor problems.

3. Who needs deep convex stoma bags?

The Deep convex stoma bag is usually used in situations where the stoma position is too low or concave, resulting in the inability of ordinary stoma bags to form an effective seal. For specific who needs deep convex stoma bags, you can refer to the following table:

Stoma condition	Symptoms	Recommendation reasons
The stoma is obviously concave	The stoma is more than 3 to 5 mm lower than the skin surface	The deep convex surface provides strong outward support, making the stoma more prominent and reducing leakage
There are deep folds and grooves around the stoma	The abdominal folds prevent the chassis from being flattened	The deep convex surface can cross the folds to form a continuous seal
Obese patients	The skin on the abdomen is soft, sagging and prone to squeezing the stoma	It provides stronger stability to prevent the bag body from being squeezed by the abdomen
Scars or depressed structures around the stoma	Surgical trauma can form scars or depressions	Deep convex surfaces can compensate for uneven areas
Poor direction of stoma opening	Excrement tends to remain on the skin	The deep convex surface can guide the flow direction of excrement
Frequent leakage cannot be solved by ordinary systems	Trying flat or shallow convex surfaces yields poor results	The deep convex surface enhances the sealing stability

When should you suggest deep convex stoma bags?

1. Insufficient stoma height

Deep convex stoma bags can make the stoma more prominent and facilitate the flow of excrement. Enhance sealing performance to prevent leakage.

2. Repeated leakage

Deep convex stoma bags can adjust uneven or skin crease areas, enhance the adhesive sealing property and reduce leakage.

3. The direction of the stoma opening is not good

For example, the stoma is tilted downward or to the side. Deep convex stoma bags can help guide the flow direction of excrement.

4. Insufficient soft tissue support around the stoma

For example, postpartum abdominal laxity, skin laxity in the elderly, etc.

5. The stoma is located in the abdominal fold or scar

Deep convex stoma bags can make the chassis fit more stably.

It should be noted that deep convex stoma bags require professional assessment; otherwise, it may cause compression injury.

How deep convex stoma bags may help to avoid stoma leakage?

1. Enhance the protrusion of the stoma

The deep convex surface structure makes the stoma more prominent, preventing excrement from continuously contacting and contaminating the skin from the source. Excrement is more likely to fall directly into the bag.

2. Repair the gaps caused by uneven skin

Such as skin folds, depressions, slopes, scars, etc. around the stoma. Deep convex stoma bags can adhere more closely to the skin, enhance adhesion and sealing, and reduce the risk of leakage.

3. Stabilize the chassis to prevent it from disengaging due to abdominal movement

It is particularly crucial for users with high levels of physical activity and elastic changes in their abdomen.

4. It works even better when combined with auxiliary materials

For example: skin barrier ring, ostomy paste, ostomy support belt, Barrier Strips, Ostomy powder, Ostomy Baseplate Adhesive Remover, etc.

Why Choose deep convex stoma bags?

1. Improve sealing performance and significantly reduce leakage

For patients with retracted stomas, stoma-surrounding folds, and obese abdomens. Deep convex stoma bags can gently apply pressure to the stoma.

Provide stable continuous sealing rings

2. Protect the skin around the stoma

Deep convex stoma bags can effectively reduce excrement leakage. Protect the skin and prevent it from being continuously contaminated by excrement. Thereby reducing skin problems.

3. Excrement flows more smoothly

For patients with loose stools and high-flow stoma, deep convex stoma bags can help guide excrement to flow naturally into the bag body. Avoid problems such as blockage and backflow.

When the opening direction of the stoma is not good, deep convex stoma bags can help guide the flow direction of excrement.

4. Enhance stability

The deep convex surface chassis, combined with elastic materials, is more adaptable to:

Bend over

Sit down

Sports

Changes in abdominal tension, etc.

Reduce the risk of leakage and be more comfortable and stable.

5. Enhance comfort and confidence

Sleep more peacefully

More freedom in sports

Work and social pressure have been relieved

Reduce psychological burden and anxiety

Which Skin Barrier is Right for You?

1. The function of skin Barrier

Fixed stoma: The Skin Barrier is adhered around the skin and plays an important role in fixing the stoma and preventing it from falling off.
Sealing effect: The Skin Barrier has adhesive properties and can firmly adhere to the skin, completely adhering to the skin to form a seal, preventing leakage and odor.

Protect the Skin: The Skin Barrier can effectively separate feces from urine.

2.Do you need a Flat, Convex or Convex Flip solution?

Flat Skin Barrier

This is the most common chassis. The Flat Skin Barrier has a smooth surface and is directly attached to the skin. It is suitable for stoma with protruding stoma and flat surrounding skin without depression.

Convex Skin Barrier

The middle protrusion provides additional pressure on the stoma. It is suitable for patients with a flat stoma, slight depression or skin folds. Help enhance the sealing between the chassis and the skin to prevent leakage.

Moldable Skin Barrier

Moldable Skin Barrier can be pulled and shaped. For some patients, the stoma shape is irregular. This can be freely shaped and perfectly fit the skin around the stoma, which can enhance the sealing property and protect the skin, reducing leakage.

Extra Ostomy Supplies to Consider

In addition to deep convex stoma bags, some additional ostomy accessories products are also indispensable.Ostomy Skin Care Powder:Helps absorb moisture and protect sensitive skin around the stoma.

Reinforced Ostomy Adhesive Patch: Provides extra security and comfort with breathable fabric support.
Medical Adhesive Remover:Gently dissolves adhesive residue for painless and easy removal.
Ostomy Baseplate Adhesive Remover:Specifically designed to remove baseplate adhesive while protecting the skin.
Ostomy Barrier Ring:Creates a secure seal to prevent leakage and protect the peristomal skin.
Ostomy Skin Barrier Film:Forms a protective layer that shields skin from irritation and adhesives.
Ostomy Skin Barrier Spray:Provides quick, even coverage with a convenient spray application.
Ostomy scissors:Help cut the size of the skin barrier opening and can effectively avoid uneven, rough and angular edges.

Do you prefer a click or a flexible adhesive coupling?

Modern two-piece stoma bags mainly have two connection systems: Click system and Flexible adhesive coupling.

	Click system	Flexible Adhesive Coupling
Connection method	The plastic lock ring “clicks” in and is fixed	The chassis and the bag body are bonded together through a flexible rubber ring
Fixed strength	Very firm	Firm but softer
Suitable for abdominal curved surfaces	It is relatively hard and has poor adaptability to curved surfaces	Very soft, suitable for curvaceous bellies
Wearing comfort	Medium, because the lock ring is relatively hard	It’s extremely high and has excellent adhesion
The impact on the skin during replacement	The snap needs to be pushed and pressed, which exerts pressure on the abdomen	Almost stress-free, suitable for sensitive skin
Auditory feedback	“Click” confirms the lock	Silent fit
Suitable user types	Those who like a distinct sense of confinement and have a high level of activity	Users with sensitive skin and a distinct curved abdomen
Whether it is suitable for deep convex surfaces	Suitable	Suitable, especially for deep convex stoma bags

Daily inspection: After taking a bath, exercising, going out or sweating, it is necessary to promptly check whether there is any leakage or lifting at the edge of the stoma bag.

· Correctly observe skin changes

When using deep convex stoma bags, it is necessary to monitor the skin regularly for signs such as severe indentations, pain, persistent redness and swelling, cyanosis or insufficient blood supply. If it occurs, stop using it immediately and go to the hospital for treatment in time.

· Pay attention to your diet

Foods and beverages that tend to produce gas: soy products, Onions, garlic, carbonated drinks, etc. Excessive gas can cause the bag to expand, increasing the risk of leakage.

Foods that tend to produce unpleasant odors: garlic, Chinese chives, eggs, fish, etc. Avoid eating foods with strong odors to prevent embarrassment in social or outdoor situations.

In social Settings, you can choose a pouch with an activated carbon filter or use deodorizing spray in advance, etc.

· Daily exercise

Stoma patients can engage in normal exercises, such as walking, jogging, yoga, swimming, etc. As long as the range of movement is not too large, it is necessary to check in time after exercising whether there is any curling or leakage. It is recommended to use a sealing ring or belt in combination to enhance skin adhesion and sealing effect.

· Daily wear

Try to wear loose, soft, light and breathable clothes. Avoid wearing overly tight or hard clothes that may squeeze the stoma. Meanwhile, loose clothing can also make the stoma more concealed. Comfortable clothing is also the key to learning how to care for a pocket.

When you should call the doctor

When the following situations occur, it is necessary to go to the hospital in time for treatment to prevent the condition from worsening further：

Sudden severe abdominal pain, vomiting, abdominal distension and other conditions may indicate intestinal obstruction.
If the color of the stoma turns dark purple or black, it may indicate insufficient blood supply to the stoma or stoma necrosis.
Massive bleeding from the stoma or abdominal wall incision;
Persistent high fever;
Severe prolapse of the stoma affects defecation function.
