一種新型注射器能夠自動(dòng)檢測(cè)硬膜外麻醉過(guò)程中阻力(LOR)的喪失，硬膜外麻醉是將藥物直接注射到硬膜外腔中。

Episure AutoDetect注射器是在硬膜外麻醉過(guò)程中，由彈簧驅(qū)動(dòng)自動(dòng)LOR注射器。這種注射器使用特殊工程內(nèi)部壓縮彈簧，對(duì)活塞使用精確而持續(xù)的力量，在硬膜外針頭進(jìn)入硬膜外腔的時(shí)候自動(dòng)縮回，從而無(wú)需麻醉師象使用標(biāo)準(zhǔn)LOR注射器那樣需要主觀“感覺”。除了提供視覺確認(rèn)之外，Episure還允許操作人員使用雙手繼續(xù)操作硬膜外針，因此可操作性和敏感性十分優(yōu)越。

Episure AutoDetect注射器是Indigo Orb公司(Irvine, CA, USA)的產(chǎn)品，已經(jīng)得到了美國(guó)食品藥品管理局(FDA)和歐盟(EC mark)的批準(zhǔn)。

New Syringe Detects Loss of Resistance
 
A new syringe automatically detects loss of resistance (LOR) during epidural anesthesia, the administering of medications directly into the epidural space.

The Episure AutoDetect syringe is a spring-loaded, automatic LOR syringe used in epidural anesthesia. The syringe utilizes a specially engineered internal compression spring that applies precise and constant force on the plunger that automatically depresses when the epidural needle enters the epidural space, eliminating the subjective "feel" required by the anesthetist with standard LOR syringes. In addition to providing a visual confirmation, the Episure allows the practitioner to continuously advance the epidural needle with both hands, resulting in superior control and sensitivity.

The Episure AutoDetect syringe is a product of Indigo Orb (Irvine, CA, USA), and has been approved by both the U.S. Food and Drug Administration (FDA) and the European Community (EC mark).
