The applications of PVC compound include disposable infusion (liquid) equipment or precision transfusion (liquid) appliances,light-proof infusion set,hemodialysis series,anesthesia and respiratory circuit series,nutrition bags,blood bags,suction tubes,and Yanke tube.
With the increase of population aging and the rising of chronic diseases,the medical services market has continued to grow.Medical PVC compound has gradually become one of the important raw materials for medical supplies and equipment.
In particular,since the 21st century,kidney disease has become one of the major hazards of human health,and hemodialysis is the current and the next few decades of end-stage renal disease (uremia) the main means.Hemodialysis therapy equipment is made up by the dialysis machine,dialyzer,blood circuit and other components,including dialysis and blood circuit for medical plastic made of medical supplies.
After years of efforts,China's medical plastics industry is gradually to the high-tech,high-end,high-quality direction,product upgrading,industrial upgrading significantly.Many companies launched needle,PTCA,Strengthen the catheter intubation,analgesic pumps and various types of anesthesia supplies products,etc.; these enterprises will inevitably bring about the upgrading of China's medical plastics industry to enhance.
Bis (2-ethylhexyl) phthalate,referred to as DEHP or DOP,is the most commonly used plasticizer in PVC process.Throughout the world of medical PVC products,it has been clearly not allowed to add 17 kinds of phthalates as plasticizers.
A large number of experiments at home and abroad proved that phthalates into the human body and animal body will have similar estrogen role,will interfere with endocrine,is a potential endocrine disruptors.At present the EU has banned toys containing DEHP ingredients.
Although the exposure time of infusion device in the infusion process is short,and medical PVC DEHP addition ratio is less,in order to maximize the safety of each infusion device users, non-phthalates type PVC material came into being.We have started to sell this product since 2008,and the initial major customers are European and American manufacturers.Since
October 20 12 the domestic medical device industry give great importance to the potential risk of DEHP,we help customers to produce,and register non-phthalates PVC infusion device.
Teamlong provides the opportunity to choose right plasticizers in order to help customers find the most suitable for their own products.
Non-PVC product applications include TPE precision blood transfusion (fluid) appliances,PP Corrugated breathing circuit,PP expandable breathing circuit,large infusion combination cover and interface.
Traditional medical PVC type products have been sold in domestic and foreign markets for more than 20 years.And in the process of long-term use of this traditional material,domestic and foreign markets have slowly raised the product level,and even gradually began to eliminate PVC material in some important use of medical field.The most direct change can be reflected in the domestic infusion industry.The domestic infusion industry has been widely used polypropylene (PP) plastic bottle instead of the original PVC infusion bag from 2000,and the past two years it has been promoted three-layer film,five-layer film to replace the original plastic bottle package.In foreign countries,the material of implantation and long-term exposure to the body has also been gradually upgraded from the PVC material to TPE,TPU and other biocompatible materials.
From the perspective of long-term development of the medical industry,medical TPE (thermoplastic elastomer) in the high-end market to replace PVC material is an inevitable trend; from the downstream production enterprises,TPE type of products can help customers achieve efficiency; from the final consumer demand,the product is also more secure and welcome.
