With the improvement of people's health awareness and medical level, the disinfection and safety of medical devices have attracted more and more attention. However, repeated disinfection can easily cause damage to medical devices, thereby affecting medical effects and service life. To this end, the editor of OFweek Medical Technology Network also interviewed Dr. Liu Yuxi, Director of Global Medical Technology Platform of Eastman Chemical Specialty Plastics Division, to discuss the optimal solution. The following is a textual record:
Dr. Liu Yuxi, Head of Global Medical Technology Platform, Eastman Chemical Specialty Plastics Division
1. What are the main products that Eastman displayed in this exhibition? What are the main performance and advantages?
Liu Yuxi: The new material introduced this time is copolyester MXF221. The impact strength of traditional medical plastics, such as acrylic, polycarbonate and other synthetic polymers, is reduced after encountering high strength disinfectants. Eastman MXF221's excellent chemical resistance makes it resistant to a wide range of strong disinfectants and maintains high impact resistance after repeated disinfection. The MXF221 also demonstrated strength over other commonly used materials in the simply supported beam impact strength test. These qualities can significantly increase the life of the medical device housing and prevent cracking and cracking.
2. In which areas is the new MXF series of products that are mainly launched? What are the unique technologies? What is the future application prospect?
Liu Yuxi: MXF221 can be applied to the outer casing of medical equipment and various structural components, such as monitors, ultrasound systems, infusion pumps, anesthesia machines, MRI/CT, ​​etc.
In response to market demand for medical devices that do not contain halogens for fire-retardant materials, Eastman MXF221 was developed using a new halogen-free formulation based on Tritan copolyester. The MXF221 is processed with fully composite pellets that are uniform in color and provide customers with custom colors. In the production process, the color masterbatch mixing factor can be eliminated, thereby improving the product yield and meeting the requirements of different colors and different transparency. Due to its excellent chemical resistance and excellent material mechanical properties, the MXF221 is a housing material that provides a solid guarantee for the safety and durability of medical devices.
3. What certifications or audits do you need to pass as a medical industry application? What are the advantages of Eastman in product development?
Liu Yuxi: MXF221 has UL94V2 fire rating and FDA medical grade.
In product development, Eastman Chemicals is the world's leading specialty chemicals company and a major producer of copolyesters worldwide. Based on a deep understanding of copolyester materials and a high level of market demand for medical devices, medical device packaging and medical device casings, Eastman attaches great importance to the development and investment of new products, oriented to customer needs, products It has a fast development speed and a short development cycle. It has been continuously innovated through the application of copolyester in infusion parts, rigid packaging, blood contact products and medical device housing products.
4. At present, how is Eastman's domestic layout and localization progressing? What is the boosting effect on the development of the domestic medical industry?
Liu Yuxi: In China, with the increasing attention to prevent hospitalization and the strict regulations on the use of antibiotics, the disinfection process and products used in Chinese hospitals are becoming more standardized and strict. Some medical products that involve blood contact, skin contact, etc. have strict standards for whether the materials are medically certified. The market has also put forward green, environmental protection and safety requirements for medical materials.
The Eastman polyester series does not contain bisphenol A, DEHP, halogen and other substances, which strongly supports the pursuit of high quality safety products produced by domestic medical equipment and equipment manufacturers. This means that domestic medical device manufacturers need to reach a higher level, requiring the device casing to have better chemical resistance, which is characterized by being able to withstand more powerful disinfectants.
As a related product, the development of disinfectant is also faced with the trade-off between the disinfection ability and the surface of the corrosive equipment. The MXF211 improves the service life of the medical device casing through better chemical resistance and impact resistance, and also reduces the development of disinfectant. Worried about it.
5. In the field of medical applications, precision medicine is gradually emerging. Is there any involvement of Eastman in this regard? What do you think of the current status and prospects of precision medicine?
Liu Yuxi: Eastman's products are not much involved in the field of precision medicine.
6. What is the performance of Eastman China as of now? What new plans and layouts are there in the future?
Liu Yuxi: At present, Eastman China's performance is very good. The MXF221 is the latest model of the MXF series and is available simultaneously in core markets such as North America, Europe and China. This also reflects the fact that China's medical product market is gradually aligning with international standards in quality control. Since its inception a few years ago, the MXF series has been introduced to major medical device manufacturers worldwide, and the number of commercialization cases is increasing. We will continue to innovate according to market demand.
Sweeteners are Food Additives that sweeten soft drinks. Sweeteners can be divided into nutritional sweeteners and non-nutritional sweeteners according to their nutritional value. According to its sweetness, it can be divided into low sweetness sweetness and high sweetness sweetness I flavor; According to its source can be divided into natural sweeteners and synthetic sweeteners. Natural sweeteners include stevia, grosvenin, licorice, disodium glycyrrhizinate, tripotassium glycyrrhizinate and trisodium.
