Medical transparent IV dressing is a kind of transparent film dressing that can breathe with skin. It is made of high permeability polyurethane film, special moisture permeable medical acrylate adhesive and special coating process.

In the growing field of medical devices and consumables, transparent IV dressings have been used everywhere. Transparent IV dressing is widely used in surgery, wound and incontinence care, monitoring, diagnosis and other aspects. The performance and performance of the final product of transparent IV dressing are closely related to that of transparent IV dressing. Therefore, in the design of medical products, how to select the transparent IV dressing with appropriate function and excellent performance has become an important topic worthy of attention of researchers.

Characteristics of transparent IV dressing and its application in medical products

In general, medical transparent IV dressing is composed of substrate, adhesive layer and release paper. Compared with other adhesive methods, transparent IV dressing has a series of advantages.

First of all, there is no need for heating, solvent modulation, mechanical reinforcement and other cumbersome process when using transparent IV dressing, which is convenient and fast.

Secondly, the transparent IV dressing is easy to keep, and the adhesive layer will not be dry and solid in a long time.

In addition, in most cases, it can be peeled from the adhered surface without damage, which is also an important advantage of transparent IV dressing. Because of these unique advantages, transparent IV dressings are widely used in medical products, especially in disposable medical products. Unique transparent IV dressing medical products are one of the categories with high risk.

Safety and comfort of transparent IV dressing

Medical transparent IV dressings have a higher chance to contact the human body in use, so we must try our best to eliminate the possibility of damage to the human body, and strive to enhance the comfort of patients. Therefore, there are some special requirements for transparent IV dressings used in medical products, which need to be considered and realized in the development process of transparent IV dressings. In fact, security is a requirement applicable to any product. The safety of medical products, industrial products and household products must be guaranteed. However, for products in different fields, the definition of security is different. For medical products, especially those that directly or indirectly contact human body, their safety is mainly reflected in environmental protection, biocompatibility, production process stability and traceability. As a component of medical products, medical transparent IV dressings must meet the requirements of environmental protection in relevant countries.

Functional requirements of transparent IV dressings

To put it simply, it's whether the paste is good or not. For transparent IV dressings, there are three aspects

First, whether the viscosity of the material is enough. When the dressing needs to stick the material to the skin, the dressing should be able to stick firmly on the surface of the material.

Second, whether the viscosity of the skin is appropriate. Since most transparent IV dressings need to stick to the skin, they should have proper, rather than stronger, better viscosity.

Third, whether it can adapt to the corresponding sterilization methods. Different sterilization methods have different effects on product performance, so it is an important part of product design to select suitable materials for sterilization methods.

With the improvement of medical level, more and more attention has been paid by medical staff and patients. For the medical products using medical transparent IV dressings, whether there is pain when tearing off, whether there is residual glue, how about the compliance and elasticity, and whether the sticking is breathable or not are the direct feelings of patients, which are the concrete embodiment of the comfort of dressings. How to translate these items into quantifiable and testable indicators is an important task for transparent IV dressing manufacturers. In addition, the choice of transparent IV dressing for one-time operation also plays a crucial role in the infection control of operating room.

The results show that when the moisture permeability of polyurethane film of transparent IV dressing is lower than that of skin, water vapor may accumulate between skin and dressing. When it is serious, it will soak the skin and affect the bonding effect between the wound healing and the skin.
