Easier, comfortable diabetic treatment

Needle-free injections made possible with polycarbonate

Easier, comfortable diabetic treatment

Diabetic treatment often requires painful injections, yet for more than 114 million Chinese patients, needle-free injection can be a viable therapy for diabetes and effective blood glucose control.¹

Needle-free injection technology
Needle-free injection technology developed by QS Medical Technology Co., Ltd.

Task

To meet the needs of a growing number of diabetes patients, QS Medical Technology Co., Ltd. (QS) developed a new needle-free injection technology. These high-quality injectors make life easier and more comfortable for millions of patients in China and around the world.

Challenge

The needle-free injector’s plastic drug-delivery components and ampoule bottle require a material that can achieve strength, toughness, precision molding stability and radiation sterilization resistance.

Solution

Featuring durability, processability and design flexibility, Makrolon® Rx1805 polycarbonate from Covestro met QS’ needs for producing the insulin-delivery interface and molding the medication ampoules. This medical-grade polycarbonate ensures that the drug-delivery component can consistently puncture through the plug of an insulin ampoule. It also allows for the drug-sampling needle and the protective cover of the drug suction apparatus to be injection molded in one shot.
