摘要： The invention relates to a catheter assembly comprising a cannula, needle and catheter inserter wherein the inserter is in slidable relationship to the cannula and wherein the inserter or other device also serves to selectively restrict the cannula and needle from sliding relative to the inserter. The cannula comprises a material which, when inserted into the body of a living subject, softens and/or swells and has a tensile energy to break of at least about 700 N-cm/cm.sup.3 and a 2.5% Secant modulus of less than about 7,000 N/cm.sup.2. The invention also relates to a method of inserting a cannula into a living subject using an inserter which is positioned such that the desired length of cannula for initial insertion extends beyond the inserter. The method also relates to further inserting the cannula into the living subject after initial insertion of the cannula.

摘要： The invention relates to a catheter assembly comprising a cannula, needle and catheter inserter wherein the inserter is in slidable relationship to the cannula and wherein the inserter or other device also serves to selectively restrict the cannula and needle from sliding relative to the inserter. The restricted movement is caused by a portion of the cannula swelling when contacted by a liquid. The invention also relates to a method of inserting a cannula into a living subject using an inserter which is positioned such that the desired length of cannula for initial insertion extends beyond the inserter. The method also relates to further inserting the cannula into the living subject after initial insertion of the cannula.

摘要： An improvement in an injection bulb device in an assembly for administration of parenteral solutions is disclosed. The device is a tubular elastomeric member having an enlarged intermediate section whose bore is larger than the bores in the two end sections. A plurality of flat-surfaced projections or rings extend inwardly from the walls of the bores in the end sections which compressively grip the end of a rigid needle adapter and flexible tubing inserted respectively within these end sections. The end of the tubing flares outwardly into the enlarged bore of the intermediate section and this configuration assists in increasing the strength of mechanical engagement between the tubing and the injection bulb.
摘要翻译：公开了用于肠胃外溶液给药的组件中的注射灯泡装置的改进。该装置是具有扩大的中间部分的管状弹性体部件，其孔径大于两个端部部分中的孔。多个平坦表面的突起或环从端部部分中的孔的壁向内延伸，所述端部压缩地夹持分别插入在这些端部部分内的刚性针适配器和柔性管的端部。管的端部向外张开到中间部分的扩大的孔中，并且该构造有助于增加管和注射灯泡之间的机械接合的强度。
