Introduction
The differences between medical underpads and sanitary napkins include intended use, execution standards, sterility requirements, material design, and applicable scenarios. The two products are developed for different purposes and are not interchangeable; appropriate selection should be based on specific usage scenarios. If improper use leads to infections, skin irritation, or other issues, medical attention is recommended. Medical underpads are used for protective isolation in medical settings.
There are several differences between medical pads and sanitary napkins, including intended use, execution standards, sterility requirements, material design, and applicable scenarios. The two products are developed for different purposes and cannot replace each other; appropriate selection should be based on specific usage situations. If improper use leads to infections or skin irritation, medical advice should be sought promptly.
1. Intended Use: Medical pads are used in medical settings for protective isolation, absorbing blood and secretions to prevent contamination. Sanitary napkins are designed for women during menstruation to absorb menstrual blood, focusing on daily physiological care and meeting hygiene needs during the menstrual period.
2. Execution Standards: Medical pads follow medical device manufacturing standards and must comply with national medical device quality regulations. Sanitary napkins adhere to consumer hygiene product standards, emphasizing comfort and absorbency, without requiring medical device certification.
3. Sterility Requirements: Medical pads must meet sterile standards, with strict control of microbial contamination during production, and should be used promptly after opening. Sanitary napkins generally meet regular cleanliness standards; although some products may be labeled as "sterile," they do not meet medical-grade sterility requirements.
4. Material Design: Medical pads prioritize leak-proof performance, breathability, and non-allergenic materials, typically featuring non-woven fabric or cotton wool surfaces. Sanitary napkins emphasize high absorption capacity and comfort, often containing superabsorbent polymers, fragrances, and other additives.
5. Applicable Scenarios: Medical pads are suitable for medical procedures such as surgery, nursing care, and examinations, as well as postoperative wound care. Sanitary napkins are intended for daily use during menstruation and are limited to external personal hygiene; they should not be used in medical contexts.
Medical pads should be purchased through正规 channels, with attention to verifying medical device registration information. When choosing sanitary napkins, opt for fragrance-free, low-allergenic materials and change them regularly to prevent bacterial growth. Both types of products should be stored according to instructions in a dry, clean environment to avoid contamination.
