What precautions should be taken during the storage and transportation of single-use sterile dressings?

The storage and transportation processes for single-use sterile dressings directly affect their quality and safety. The following are relevant precautions:

I. Storage Precautions 
 

1. Environmental temperature and humidity control

Single-use sterile dressings should be stored in a dry environment, with relative humidity generally maintained between 45% and 75%. Excessively high humidity may cause the dressings to become damp, compromising their performance and even fostering microbial growth; conversely, excessively low humidity may lead to the dressing materials drying out and becoming brittle, thereby reducing their flexibility.

Regarding temperature, the storage temperature is typically required to be between 10°C and 30°C. Temperatures that are too high may accelerate the aging and deterioration of the material, while temperatures that are too low may affect the physical properties of the patch, such as the adhesiveness of the adhesive.

2. Warehouse Environment Management

The warehouse should be kept clean and tidy, with smooth floors, walls, and ceilings free of cracks to facilitate cleaning and disinfection. The warehouse should be regularly swept and disinfected to prevent the entry of contaminants such as dust and insects.

The warehouse should have good ventilation to ensure air circulation, reduce humidity, and eliminate odors. Ventilation equipment, such as exhaust fans, can be installed to keep the air fresh.

Direct sunlight should be avoided in the warehouse, as ultraviolet rays in sunlight can degrade the adhesive material and compromise its performance. The patches can be stored on the lower shelves or protected with shade facilities.

3. Store separately

Store products categorized by specifications, models, batch numbers, and other relevant criteria to facilitate management and retrieval. Adhesive patches of different specifications and models may have varying uses and performance requirements; keeping them separately prevents confusion.

For patches nearing their expiration date, they should be labeled and used first to prevent waste due to expiration.

4. Inventory Management

Establish a comprehensive inventory management system, conduct regular inventory counts, and ensure that book records match physical stock. Promptly remove expired, deteriorated, or damaged products to prevent them from entering the market.

Record information such as the time of product inbound and outbound, quantity, batch number, etc., to facilitate traceability and inquiry.

II. Transportation Precautions 
 

1. Selection of transportation means

Select the appropriate mode of transportation, such as box trucks or refrigerated vehicles. For patches that are stored at room temperature, the box truck should have excellent sealing capabilities as well as resistance to rain and sunlight. For patches that require refrigerated storage, a refrigerated vehicle must be used, and the temperature inside the vehicle must meet the specified requirements.

Transportation vehicles should be kept clean and hygienic, regularly disinfected, and protected from contaminating products.

2. Temperature Control

During transportation, temperature must be strictly controlled. For dressings stored at room temperature, the ambient transportation temperature should be maintained between 10℃ and 30℃. For dressings that require refrigeration, a temperature logger should be used to monitor the vehicle’s internal temperature in real time, ensuring that the temperature remains within the specified range (typically 2℃ to 8℃).

If the transportation time is relatively long, appropriate thermal insulation measures should be taken, such as using insulated containers or ice packs, to ensure that the product’s temperature remains stable.

3. Shock and compression resistant

During transportation, the patch should be protected from severe vibrations and compression to prevent damage to the product. Buffering materials such as foam or sponge can be used for packaging and isolation to minimize the effects of vibration and compression.

Arrange the stacking height and method of goods reasonably to avoid excessive pressure from upper-layer goods on lower-layer goods.

4. Shipping Time

Minimize transportation time and reduce the exposure duration of products during transit. Arrange transportation routes and schedules rationally to enhance transportation efficiency.

5. Document Records

During transportation, relevant documentation should be properly maintained, including the shipping time, receipt time, transportation route, and temperature records. These records can serve as the basis for product quality traceability and liability determination.
