This invention regards the device in order to fill the liquid to the body of the patient (10). This device pulls and pulls out and includes, the needle where it is intended that it is inserted in the body, (22) the base where it supports (20) with, the needle (22) the fill pipe which is connected (24) with, needle use position and the needle in order to be able to slide position the base (20) vis-a-vis with, the plunger which is installed (52), the needle (22) it pulls from the patient and the expedient which is pulled out (26) with, the needle (22) pulls and when making a foolish mistake, the fill pipe (24) the expedient which generates overpressure (28) with, possesses. The expedient which generates overpressure (28), the fill pipe (24) the flexible area which is published (53) with, the plunger (52) the cam surface which is connected hard (54) with, the base (20) the support surface which is connected hard and, it possesses, the plunger (52) pulls and pulls out and the needle when sliding facing toward position, the aforementioned flexible area (53) radial and the needle (22) compresses vertically with the cam surface and the support surface. This invention includes flexible area (53) the needle (22) expedient in order to maintain substantially vertically (56).< Selective figure >Figure 2本発明は、患者の身体に液体を注入するための装置(10)に関する。この装置は、身体に挿入されることが意図された針(22)を支持するベース(20)と、針(22)に接続された注入導管(24)と、針使用位置と針引き抜き位置との間でベース(20)に対してスライドできるように取り付けられたプランジャ(52)を含む、患者から針(22)を引き抜く手段(26)と、針(22)が引き抜かれるときに注入導管(24)に過圧を発生させる手段(28)と、を有する。過圧を発生させる手段(28)は、注入導管(24)に掲載された可撓性区域(53)と、プランジャ(52)に固く接続されたカム表面(54)と、ベース(20)に固く接続された支持表面と、を有し、プランジャ(52)が針引き抜き位置に向かってスライドするときに、前記可撓性区域(53)をカム表面と支持表面との間で半径方向および針(22)に垂直に圧縮する。本発明は、可撓性区域(53)を針(22)に実質的に垂直に維持するための手段(56)を含む。【選択図】図2
