摘要： A needle guard includes a clip with a canting wall to grip the needle shaft and a distal wall to block the tip thereof, wherein the canting and distal walls may be interconnected by an angled strut so as to allow the canting wall to be tilted over center in a ready state, a spring member, such as a leaf spring, may have a portion extending past an edge of the strut to bias the clip to grip the needle shaft.

摘要： A safety cover, which securably and reliably prevents the readvancement of the tip of a cannula once it has been retracted thereinto, is designed having an elongate body which includes an axial channel having elements which displace and block linear passage of the cannula once it has been retracted. In a first embodiment the displacing elements are inwardly and rearwardly extending bristles which provide for unidirectional motion of the cannula relative to the safety cover, thereby locking the cannula once it has been retracted. In a second embodiment, the displacing element is the axial channel itself which has a curvate bias and distorts into a non-linear path once the cannula is retracted. In a third embodiment, the displacing element is a spring plate which, when compressed permits the cannula to pass through, but once the cannula has been retracted, expands to prevent the tip from being readvanced.

摘要： A catheter insertion device is provided in which a needle cannula thereof has one or more markers to provide a visual and/or tactile indication to a user that the needle cannula has been withdrawn from a position in which the sharp tip thereof is exposed beyond the catheter tube to a position wherein a part of the cannula needle shaft and the tip are within a proximal portion of the catheter tube so as to impede fluid leakage through the tube, but removed from a distal portion of the tube to free it to flex.
摘要翻译：提供一种导管插入装置，其中针插管具有一个或多个标记，以向使用者提供视觉和/或触觉指示，即针插管已经从其尖端暴露于导管之外的位置撤回管到一个位置，其中套管针轴和尖端的一部分在导管管的近端部分内，以便阻止流体通过管的泄漏，但是从管的远端部分移除以使其弯曲。

摘要： A catheter insertion device incorporating a simple lever and clip structure which will safely lock a catheter hub of a catheter assembly to a normally disposable cannula housing and guard structure and which, in a simple mode, enables separation of the catheter hub from the cannula assembly or structure upon retraction and protective guarding of the used cannula. Specifically, an aspect resides in providing the lever release clip for a safety catheter which upon unlocking and releasing of the catheter hub concurrently pushes the catheter hub off a nose guard of the cannula assembly, while enabling a physician or clinical personnel to release the catheter by employing only one hand. A further embodiment is adapted to enable separation between the catheter hub of a flexible catheter and the needle or cannula arrangement of a catheter insertion device by simply manipulating a lever arranged on a cannula structure or nose guard thereof by simply pushing against a push-tab element.
摘要翻译：导管插入装置，其包括简单的杠杆和夹子结构，其将安全地将导管组件的导管套管锁定到通常的一次性插管壳体和护罩结构，并且以简单的模式能够将导管套管与插管组件分离，退回时的结构和使用的插管的保护性防护。具体来说，一方面在于提供用于安全导管的杠杆释放夹，其在解锁和释放导管套管同时将导管套管从插管组件的鼻部护罩推出时，同时使医师或临床人员能够通过只用一只手。进一步的实施例适于通过简单地操纵布置在插管结构或其鼻保护罩上的杆来简单地推动推襻元件，从而能够使柔性导管的导管套管与导管插入装置的针或插管装置间隔开。
