    • A needleless, three-shot, variable dose jet injector (1) comprises a body portion (2) having a passageway (5) and a trigger (7), a cylinder portion (11) onto which a medicament vial (17) can be screwed in order to vary the dose to be applied and a piston head (16) movable within the cylinder portion (11) to move a plunger (15) into the vial (17). The vial (17) has a bore (20) containg the medicament which exits through an orifice (19) under pressure from a plug (21) moving under actuation from the plunger (15). The piston head (16) is caused to move by the release of gas from one (28) of three chambers in a gas capsule (27) through an exit port (43) into the passageway (5) due to the trigger (7) opening a valve (31). The passageway (5) is arranged so as to only align with the exit port and valve of one of the three chambers at a time, so that, by rotating the capsule (27), three shots of gas can be provided in a single capsule.
    • 无针,三射,可变剂量射流喷射器(1)包括具有通道(5)和触发器(7)的主体部分(2),气缸部分(11),药物小瓶(17)可以在其上 拧紧以改变要施加的剂量和可在气缸部分(11)内移动以将柱塞(15)移动到小瓶(17)中的活塞头(16)。 小瓶(17)具有孔(20),所述孔(20)包含药剂,所述药物在来自于从所述柱塞(15)的致动下移动的塞子(21)的压力下通过孔口(19)离开。 由于触发器(7),活塞头(16)通过将气体从气囊(27)中的三个腔室(28)中的一个(28)通过出口(43)释放到通道(5)中而移动, 打开阀(31)。 通道(5)被布置成一次只能与三个腔室中的一个的出口和阀对齐,使得通过旋转胶囊(27),可以在单个胶囊中提供三个气泡 。

    • A needleless jet injector device (100) for use with separate storage tanks of gas and medicament, the device (100) comprising a body having a gas inlet for connection to the gas storage tank and a medicament inlet for connection to the medicament storage tank, an active chamber for receiving medicament and having a jet nozzle (1) through which the medicament is discharged, the active chamber further receiving a piston head (3) movable to force the medicament through the nozzle (1) upon movement of the piston head (3) in the chamber towards the nozzle (1), the piston head (3) being connected to a piston (9) movable within a gas chamber (24) within the body, and means (14, 15, 20) for selectively allowing gas to enter the gas chamber (24) so as to move the piston (9) and the piston head (3) to discharge medicament through the nozzle (1).
    • 一种用于气体和药物的单独储存罐的无针喷射器装置(100),所述装置(100)包括具有用于连接到气体储存箱的气体入口的主体和用于连接到药物储存箱的药物入口, 用于接收药物并具有喷射喷嘴(1)的活性室,药物被排出,主动室还容纳活塞头(3),活塞头(3)可在活塞头(1)移动时使药物通过喷嘴(1) 3)在腔室中朝向喷嘴(1),活塞头(3)连接到可在主体内的气体室(24)内移动的活塞(9),以及用于选择性地允许 气体进入气室(24),以使活塞(9)和活塞头(3)移动,从而通过喷嘴(1)排出药剂。
