Adhesive Skin Barrier with Non-Woven Border

Product Introduction 

An ostomy pouch skin barrier is a medical auxiliary component designed specifically for patients after ostomy surgery. It is used to adhere to the skin around the stoma to form a sealing layer to collect excreta (such as feces or urine), prevent leakage and protect skin health.

Main types of ostomy skin barrier 

Ostomy pouch bases are categorized into two types based on their structure and function:

One-piece type: This is molded integrally with the ostomy pouch and can be used and replaced as a single unit after application. Advantages include ease of use, soft, discreet material, and suitability for individuals with flexible hands and feet, as well as the elderly.

Two-piece type: This base is separate from the pouch and secured with a connecting ring. The base can be attached separately, while the pouch can be removed for cleaning or replacement, allowing for flexible care (e.g., adjusting the pouch shape during exercise or travel).

Additionally, the following types of bases are categorized based on stoma shape:

Flat base: This is suitable for cases where the stoma protrudes above the skin surface and the surrounding skin is smooth.

Convex type: This is used when the stoma is below the skin surface, has a concave area around it, or is a hernia. Pressure is applied to enhance the seal. This is often secured with a belt.

How to choose the right skin barrier 

The selection should be based on the characteristics of the stoma and individual needs:

‌Size Matching‌: The center hole diameter of the baseplate should be 2–3 mm larger than the stoma (with the edge approximately 1 mm from the stoma mucosa). A larger size can lead to leakage, while a smaller size can compress the stoma and affect blood circulation.

‌Conformal Matching‌:

If the stoma is protruding and the skin is flat, choose a flat baseplate.

If the stoma is flat, concave, or poorly positioned (e.g., near the iliac crest): A convex baseplate is preferred.

‌Type of Excreta‌:

If the stoma is loose or urine (e.g., an ileostomy): Choose an open-mouthed baseplate with a drain valve for easy emptying.

For formed stool: A closed-mouthed baseplate can be used.

If there is weight change (e.g., postoperative weight gain or weight loss) or if the stoma is poorly positioned, the baseplate type should be reassessed.

How to use

Improper adhesive application is the primary cause of leakage, and proper application is essential:

Skin Preparation: Clean the skin around the stoma with warm water to remove oil and secretions; dry thoroughly (residual moisture will reduce adhesion).

Enhancing Adhesion (Optional): Apply stoma skin care powder to absorb moisture, then apply a protective film; or gently heat the base with a hair dryer to improve adhesion.

Tensionless Application: Remove the base backing paper, hold the edge (avoiding contact with the adhesive surface), align the center hole with the stoma, and smooth from the bottom up and from the center outward to the sides, releasing any air. After application, press firmly with the palm of your hand for 10–15 minutes to secure the area.

Assisted Fixation: Elevate wrinkled skin with a hydrocolloid dressing or leak-proof ointment. Use a belt or reinforcement patch (such as a Y-shaped patch) for active use.

Replacement frequency and timing

The lifespan of the base plate adhesive is affected by the amount of fecal matter and skin condition:

‌Normal cycle‌: Change every 2–5 days; with minimal fecal matter and proper care, this can be extended to 3–5 days.

‌Signals for urgent replacement‌:

Fecal matter exceeds 1/3 of the bag's capacity.

80% of the base plate is white, the edges are curling, or it is leaking.

Skin allergic reactions such as redness, swelling, and pain occur.

Urostomies or ileostomies (where fecal matter is highly corrosive) require more frequent changes (approximately daily).

 leakage problems and solutions

The main causes of leakage include incorrect base plate size, improper attachment, or negligent care:

‌Base plate cut too large‌: If the center hole is too large, excrement can flow under the base plate and corrode the gel. A temporary solution is to fill the gap with leak-proof paste, but the base plate should be replaced as soon as possible.

‌Poor attachment‌: Inadequate skin cleansing or trapped air can cause the edges to warp. To address this, round the base plate corners and apply pressure with your fingertips for 10 seconds.

‌Excessive excretion: Loose stool or urine should be discharged promptly (empty the bag when it is 1/3 full) to prevent gravity from pulling on the base plate. For those with excessive gas discharge, use a bag with a carbon sheet.

If leakage persists, the stoma position should be checked to see if surgical adjustment is necessary.

Precautions and contraindications

Intended Use: Temporary or permanent stomas (such as colon, ileum, or urinary stomas), especially when excreta are corrosive.

Contraindications: Contraindicated in patients with excessive skin exudate, deep tissue damage (such as diabetic foot ulcers), or polyurethane allergies. Seek medical attention first in the event of stoma stenosis or infection.

Daily Care: Change the disc early in the morning on an empty stomach; keep the disc in a urine bag at night to prevent soaking; store in a dry, room-temperature environment (avoid high temperatures and sunlight).

High-Risk Groups: Patients with diabetes or vascular disease require medical supervision for use even on minor wounds.

Tips: If a rash, severe pain, or widespread redness or swelling develops after application, remove the disc immediately and seek medical attention.

Consult a professional stomatologist to ensure the disc is suitable for your individual needs.
