Title
(EN) DRUG RESERVOIR FOR SEPARATE STORAGE OF SUBSTANCES
(ZH) 用于物质的独立储存的药物储存器
Abstract
(EN) The present invention provides a drug reservoir (1) comprising a reservoir body (2) extending between an outlet end (4) and a proximal end (7), a front piston (8) arranged in a pre-use position within the reservoir body (2) between the outlet end (4) and the proximal end (7), a rear piston (9) arranged within the reservoir body (2) between the front piston (8) and the proximal end (7), a distal chamber (10) defined by the outlet end (4), a first portion of the reservoir body (2), and the front piston (8), the distal chamber (10) holding first contents (18), a proximal chamber (11) defined by the front piston (8), a second portion of the reservoir body (2), and the rear piston (9), the proximal chamber (11) holding second contents (12, 19) comprising a proximal liquid volume (19), and bypass means (3) allowing fluid flow past the front piston (8) in an advanced position of the front piston (8) in the reservoir body (2), wherein the second contents (12, 19) further comprises a proximal gas volume (12) lying within a volume range having a predetermined minimum value.
(ZH) 本发明提供了一种药物储存器(1),所述药物储存器包括在出口端(4)和近侧端(7)之间延伸的储存器主体(2),在使用前位置在储存器主体(2)内布置在出口端(4)和近侧端(7)之间的前活塞(8),在储存器主体(2)内布置在前活塞(8)和近侧端(7)之间的后活塞(9),由出口端(4)、储存器主体(2)的第一部分和前活塞(8)限定的远侧腔室(10),远侧腔室(10)保持第一内容物(18),由前活塞(8)、储存器主体(2)的第二部分和后活塞(9)限定的近侧腔室(11),近侧腔室(11)保持包括近侧液体体积(19)的第二内容物(12、19),以及旁路装置(3),所述旁路装置允许流体在储存器主体(2)中的前活塞(8)的前进位置流过前活塞(8),其中第二内容物(12、19)还包括处于具有预定最小值的体积范围内的近侧气体体积(12)。
