Johnson&Johnson开发出经皮系统帮助患者控制疼痛

 
 
一种无针电子经皮系统能够帮助患者在术后控制止痛药的水平。

Ionsys设备是由Johnson & Johnson公司(New Brunswick, NJ, USA)Alza分部制造的，是一种紧凑的非侵入的独立的预置程序的止痛系统，设计用于贴附在患者上肢或者胸部。该系统使用低水平电流传送程序预置剂量的阿片类止痛药芬太尼，该药储存于包含两个水凝胶储存池的贴附条带，在按动按钮之后能够通过皮肤直接进入血液。该系统有内置安全设置，确保患者不会过度使用药物，只能够由医院相关人员才能设置，这是因为芬太尼能够导致危及生命的呼吸抑制。该系统已经获得了欧洲委员会(EC)和美国食品药品管理局的批准。
 
Transdermal System Helps Patients Control Pain
 
A needle-free electrical transdermal system helps patients control levels of painkillers after surgery.

The Ionsys device, made by the Alza division of Johnson & Johnson (New Brunswick, NJ, USA), is a compact, noninvasive, self-contained, and pre-programmed analgesic system, designed to adhere to a patient's upper arm or chest. The system uses a low-level electrical current to deliver preprogrammed amounts of an opiod painkiller called fentanyl from an adhesive strip containing two hydrogel reservoirs on the skin directly into the bloodstream with the push of a button. The system has built-in safeguards to ensure that patients do not overmedicate themselves, and is intended for use in a hospital setting only, since fentanyl can cause life-threatening respiratory depression. The system has been cleared by both the European Commission (EC) and the

U.S. Food and Drug Administration (FDA).
