Standardized Operating Procedure (SOP) for Ultra-Large Area Disinfection

1. Pre-Operative Skin Preparation: Thoroughly clean the intact skin surface of the target area (whole limb, trunk, or large surgical site) using mild soap or normal saline to remove surface dirt, oil, hair, and other impurities. Dry the skin completely with a sterile towel, ensuring no moisture remains on the skin, as residual moisture can dilute the antiseptic solution and reduce disinfection efficacy. This step is critical for optimal antiseptic performance and long-lasting antibacterial activity.

2. Sterile Product Unpacking: Locate the easy-tear notch on the individual sterile pouch, and peel open the packaging carefully without touching the sponge head to maintain its sterility. Grasp the applicator handle firmly with one hand, keeping the sponge head facing downward to prevent accidental solution leakage before activation. Avoid contact between the sponge head and any non-sterile surfaces to prevent cross-contamination.

4. Solution Activation: Turn the activation switch on the applicator handle  and release the antiseptic solution. Hold the applicator steady for 2-3 seconds to allow the solution to fully absorb into the sponge head, ensuring complete saturation before application.

5. Uniform Application & Scrubbing: Gently press the saturated sponge head against the skin, applying light, even pressure to release the solution gradually. Wipe the entire target area in slow, overlapping strokes to ensure full coverage, avoiding missed spots or over-saturated areas. For dry skin surfaces (limbs, trunk, abdomen), scrub gently back and forth for 30 seconds; for moist skin folds (inguinal, axillary areas), extend the scrubbing time to 2 minutes to ensure thorough disinfection in hard-to-reach areas.

6. Excess Solution Removal: Use a large sterile prep towel to absorb any pooled antiseptic solution on the skin surface immediately, as pooled solution may cause skin irritation or dryness. Do not wipe or blot the disinfected area aggressively, as this can remove the antiseptic layer and reduce long-term antibacterial efficacy.

7. Air Drying & Disposal: Allow the disinfected area to air dry completely before proceeding with surgery or invasive procedures. The drying time is a minimum of 3 minutes for hairless skin and up to 1 hour for hairy skin areas. This is a single-use device; discard the applicator and any unused solution immediately after use in accordance with medical waste disposal regulations, and do not reuse, re-sterilize, or repackage the device.

Frequently Asked Questions (FAQ) for Clinical Use

Q1: Is this applicator flammable during use, and what precautions should be taken?

A: Yes, the product contains 70% isopropyl alcohol, which is highly flammable before the skin is completely dry. During use and until the skin is fully dry, keep the area away from open flames, electrostatic generators, high-temperature equipment, and any ignition sources. Do not use near electrosurgical equipment until the skin is completely dry to eliminate fire risks.

Q2: Can this product be used on damaged skin, open wounds, or mucous membranes?

A: No, this applicator is strictly designed for external use on intact skin only. It is not suitable for open wounds, broken skin, eyes, ears, nasal passages, oral mucosa, or genital mucous membranes, as contact with these areas may cause severe irritation or chemical damage.

Q3: Can the applicator be reused or re-sterilized for multiple patients?

A: No, this is a single-use disposable medical device. Reuse, re-sterilization, or repackaging will lead to cross-contamination between patients, reduced disinfection efficacy, and increased infection risks. Each applicator must be used for one patient only and discarded immediately after use.

Q4: What should be done if skin redness, itching, or irritation occurs after use?

A: In rare cases, individuals with sensitive skin may experience mild irritation. If redness, itching, swelling, or allergic reaction occurs, discontinue use immediately, rinse the affected area with plenty of normal saline, and consult a medical professional for appropriate treatment if symptoms persist.

Q5: What is the correct storage method for this product?

A: Store in a cool, dry, well-ventilated environment at a temperature between 15-30℃, away from direct sunlight, high humidity, heat sources, and flammable materials. Do not freeze or expose to temperatures above 40℃, as extreme temperatures can damage the product and reduce antiseptic efficacy. Keep out of reach of children and non-medical personnel.

Common Usage Misconceptions & Avoidance Strategies

Many clinical staff have common misconceptions when using large-capacity applicators, which can affect disinfection efficacy and product safety. The first misconception is that “l(fā)onger scrubbing time means better disinfection”, but excessive scrubbing beyond the recommended time can damage the skin’s natural barrier, leading to dryness and irritation, and does not improve disinfection efficacy. It is crucial to follow the recommended scrubbing times of 30 seconds for dry areas and 2 minutes for moist folds.

The second misconception is that “using less solution saves consumables”, but insufficient solution application results in incomplete coverage and reduced antibacterial activity, increasing infection risks. the full sponge saturation is required for optimal performance. The third misconception is skipping air drying and directly covering the area with drapes, which traps moisture and reduces the antiseptic’s long-acting effect. Full air drying is mandatory to ensure the antiseptic forms a protective layer on the skin.

Additionally, some users may activate the ampoule multiple times, causing solution leakage and waste, or touch the sponge head during unpacking, leading to cross-contamination. Strict adherence to the standardized operating procedure and avoiding these misconceptions ensures maximum disinfection efficacy, patient safety, and optimal product performance.
