NEST TSA Disposable Pen Injector Assembly

Traditional pen injectors require the threaded rod to extend a certain distance during use and demand continuous pressing force during injection, which places certain requirements on the user’s hand size and operating technique. To enhance the user experience, the NEST TSA disposable pen injector assembly features a non-protruding button design. It utilizes an internal spring to store mechanical energy, enabling easy drug delivery with a simple press. The injection process becomes easier, allowing patients with limited dexterity or poor vision to self-administer. This product is primarily intended for the injection of insulin, GLP-1 receptor agonists, such as insulin degludec, semaglutide, and liraglutide, commonly used for diabetes treatment or weight management.
