摘要： A needle protector that protects the tip or distal end of a cannula, a trocar, or a cannula/trocar combination, is provided by an extruded tubing that has at least a section thereof that includes one or a plurality of protrusions or protuberances that are configured in a given fashion so that there is a slight bend created at that section of the tube, when the tube is fitted onto a cannula or trocar with the protrusions coming into contact with the outer diameter surface of the cannula or trocar. This results in friction contact between the protrusions and the cannula or trocar to maintain the tube protector in place relative to the cannula or trocar. The protrusions may be punched or lanced in the tube to a given depth towards the interior of the tube to establish a given friction contact.
摘要翻译：通过挤出管道提供保护插管，套管针或插管/套管针组合的尖端或远端的针保护器，该挤压管道至少包括一部分，其包括一个或多个配置的突起或突起以给定的方式使得在管的该部分处产生轻微的弯曲，当管被装配到套管或套管针上时，突起与套管或套管针的外径表面接触。这导致突起与套管或套管针之间的摩擦接触，以将管保护器相对于插管或套管针保持在适当的位置。突出物可以在管中冲压或拉成一定深度朝向管的内部以建立给定的摩擦接触。

This results in friction contact between the protrusions and the cannula or trocar to maintain the tube protector in place relative to the cannula or trocar. The protrusions may be punched or lanced in the tube to a given depth towards the interior of the tube to establish a given friction contact so that a predetermined force is required to be exerted in order to separate the tube protector from the cannula, trocar or a combination where the trocar is fitted into the cannula with the tip of the trocar extending beyond the distal end of the cannula.

摘要： A connector and method of connecting are described for connecting a first and second catheter at an overlap area where the first catheter fits within the second catheter. The connector includes a collar that surrounds a portion of the overlap area and a clamp that applies a radially inward force to the collar and encircles a portion of the overlap area.

摘要： A portal access device that is adapted to provide long term access to a port implanted in a patient has two major components, an infuser assembly and a safety needle insertion device. The infuser assembly has an infuser housing that can be configured into a specific shape, for example a dome. A blunt cannula is attached to and extends downwardly from the underside of the infuser housing. Also connected to the infuser housing, preferably at a side thereof, is a tubing or catheter. The safety needle inserter assembly has a base having a proximal portion that is configured to form fit over the infuser housing. At the distal portion of the base uprights are provided so that a second end of an arm, to which first end a needle or a sharp cannula is connected, may be movably and hingedly connected to the base. The sharp cannula extends from the underside of the proximal end of the arm and passes through the base by way of a bore formed at the proximal portion of the base. The bore is defined between an opening at the underside of the base and an opening at the upper surface of the base. Locking mechanisms are provided at the base uprights and the distal end of the arm so that when the arm is moved away from the base, and as the distal end of the arm pivots about the uprights, the respective locking mechanisms provided at the arm and the base would coact to lock the arm in place, to thereby maintain the tip of the needle within the bore formed in the base. To use, the safety needle inserter is placed over the infuser assembly, with the sharp cannula extending through the infuser housing and axially mating with the blunt cannula of the infuser assembly, but with the tip of the sharp cannula protruding beyond the tip of the blunt cannula. The combined needle inserter/infuser assembly is pressed down onto the skin surface of the patient so that the combination sharp/blunt cannulas penetrate the patient and puncture the self-sealing septum of a portal reservoir implanted in the patient. Once the safety needle inserter is removed from the infuser assembly, with the infuser housing septum being self-sealing, a closed fluid communication path is established between the portal reservoir and a fluid store that may be connected to the catheter of the infuser assembly. Long term access of the implanted portal reservoir is thereby achieved.
