Abstract:
(EN) A plunger assembly (14A) for a drug solution dosage device (10) is provided with: a feed screw (48) that has a male thread part (62) and an extension part (63); a first plunger (50) to which a first female thread part (68a) is provided; a second plunger (52) which has a nut housing part (88); a nut member (54) to which a second female thread part (54a) is provided; and a base part (56) which guides the second plunger (52). The nut housing part (88) houses the nut member (54) in such a manner as to prevent the rotation of the nut member while allowing same to move in the axial direction thereof.
(FR) Un ensemble piston (14A) pour un dispositif de dosage de solution médicamenteuse (10) comprenant : une vis d'alimentation (48) qui a une partie de filetage mâle (62) et une partie d'extension (63); un premier piston (50) auquel une première partie de filetage femelle (68a) est prévue; un second piston (52) qui a une partie de logement d'écrou (88); un élément écrou (54) auquel une seconde partie de filetage femelle (54a) est prévue; et une partie base (56) qui guide le second piston (52). La partie de logement d'écrou (88) loge l'élément écrou (54) de manière à empêcher la rotation de l'élément écrou tout en permettant à celui-ci de se déplacer dans la direction axiale de celui-ci.
(JA) 薬液投与装置(10)のプランジャ組立体(14A)は、雄ねじ部(62)及び延出部(63)を有する送りねじ(48)と、第1雌ねじ部(68a)が設けられた第1プランジャ(50)と、ナット収容部(88)を有する第2プランジャ(52)と、第2雌ねじ部(54a)が設けられたナット部材(54)と、第2プランジャ(52)をガイドするベース部(56)とを備える。ナット収容部(88)は、ナット部材(54)を回転不可能且つ軸方向に移動可能に収容する。
