Embodiment Construction

[0058] Figure 1-3 One embodiment of an infusion set is shown. The infusion set includes an infusion part OB and a connecting piece OA. The infusion part OB comprises a base 2 having a main plane substantially parallel to the patient's skin when the infusion set is attached to the patient's body. Said base 2 comprises a first set of guides 13 which, in this embodiment, have the form of two stabilizing fins. The base also comprises two retaining means 4 extending from the upper surface of the base, in this embodiment in the form of two steps. On the inner surface of the infusion part, an adhesive support 1, which is an adhesive plaster in this embodiment, is arranged. A cannula 5 extends from the base 2 and penetrates the adhesive support 1 in fluid communication with the central cavity 3 . The cannula 5 is preferably a soft cannula, but can also be made of metal. A cavity 3, optionally covered by a film, is adapted to receive a cannula 6 extending from said connection. e...

Abstract

The present invention relates to an injector device, an infusion set for intermittent or continuous administration of a therapeutic substance such as insulin. This ejector device for subcutaneously introducing a cannula on an infusion component into a patient's skin includes a housing, a back and a longitudinally extending guide, a member capable of longitudinally sliding inside the housing for inserting the cannula An insertion needle, a spring between the back of the housing and the longitudinally slidable member, locking means for maintaining the spring in a compressed state, and release means for disengaging the locking means. The ejector device also includes a pivot member swingable from a position allowing insertion of a needle to a position in which the pivot member encloses the needle.

Description

technical field [0001] 本发明涉及一种引射器装置,用于间歇或者连续地施用诸如胰岛素这样的治疗物质的输液套装。输液套装包括带有用以刺入病人皮肤内的插管的输液部件,和用于将输液部件与医药装置(优选是诸如胰岛素泵这样的医药输送装置)连接起来的连接件。 [0002] 所述输液套装在其组装形式下具有基本上平整的后侧面和相对其厚度较大的宽度,由此容许其平贴在病人的皮肤上,并且由此减轻了承载该输液套装所产生的不 comfortability. [0003] 根据本发明的引射器装置尤其适用于这种情形,即病人希望或者必须在没有专业人员协助的条件下由自己插入所述输液部件。 Background technique [0004] 美国专利US5522803公开了一种具有输液部件和连接件的输液套装。所述输液部件包括与用于从所述连接件接收针头的凹腔液体连通的柔软塑料插管,两个倾斜的导向孔以及两个保持装置;所述连接件包括插管,两个正方形导向销以及两个带有钩部的臂,所述钩部用于抓持住所述输液部件上的保持装置并在所述输液部件的主平面中操作。 [0005] 许多病人,比如胰岛素病人,必须或者可能希望自己插入输液装置或者放置皮下传感器等等。对于某些人来说,自己进行皮肤刺入是一个困难的过程,由此他们需要一种装置来在该过程中协助他们,由此使得所述过程不再成为一个大问题。 [0006] 文件US2003 / 0225373公开了一种用于将输液部件和传感器插入病人体内的插入装置。这种装置包括壳体、螺旋弹簧、安全装置以及用于倾斜插入病人体内的部件。但是,这种设备在工业化制造方面相对复杂,并且这种装置必须由病人通过相当复杂的过程来手动装载。 [0007] WO03 / 026728A1公开了一种引射器装置,包括壳体、弹簧、可滑动的杆、锁定机构以及针头。 Contents of the invention [0008] 本发明的目的在于提供一种改进的插入装置,其易于制造并且适合于以装载形式交付,或者至少便于装载。特别是,可能具有某些运动机能问题的老年人,需要一种以预装载形式出现的插入装置。 [0009] 根据本发明,提供了一种用于将输液部件上的插管皮下导入病人皮肤的引射器装置。这种引射器装置包括壳体,背部以及纵向延伸的导向装置,能够在...
