    • The invention relates to an apparatus and a method for simultaneous multiple medicine administration. Apparatus and systems for simultaneous multiple medicine administration of prior art have the disadvantage of medicine flow rates being dependent on each other i.e. changing a particular flow rate leads to a change in the other flow rates. Moreover, the changed flow rate does not reach a set value in a short period of time but fluctuates around the set value for an undesired long period of time. This results in a wrong dosage of all medicines, if the flow rate of one medicine is adjusted, and can cause a serious damage to a patient since some medicine have a very narrow therapeutic range of safety. The apparatus according to the invention eliminates this disadvantage and provides an almost exact dosage when administering multiple medicines simultaneously. The apparatus according to the invention comprises a housing in which at least two entry chambers and a collecting point are formed, wherein each entry chamber communicates with the collecting point via a flow path respectively and wherein in each flow path at least one penetration member is arranged, which causes a decrease in pressure downstream the penetration member with respect to the pressure upstream the penetration member. According to the method of the invention the independency of flow rates is eliminated irrespective of the equipment that is used, wherein a fluid is fed to a collecting point via separate flow paths and at least one penetration member is arranged within each flow path causing a decrease in pressure downstream the penetration member with respect to the pressure upstream the penetration member. The fluids eventually converge at the collecting point.
    • 本发明涉及一种用于同时多次给药的装置和方法。 用于同时多次给药现有技术的装置和系统具有药物流速相互依赖的缺点,即改变特定流速导致其它流量的变化。 此外,改变的流量在短时间段内没有达到设定值,而在不期望的长时间段内在设定值附近波动。 如果调整一种药物的流量,则可能导致所有药物的剂量不正确,并且可能对患者造成严重损害,因为一些药物具有非常窄的治疗安全范围。 根据本发明的装置消除了这种缺点并且在同时施用多种药物时提供了几乎精确的剂量。 根据本发明的装置包括壳体,其中形成有至少两个进入室和收集点,其中每个进入室分别经由流动路径与收集点连通,并且其中在每个流动路径中布置有至少一个穿透构件 ,其导致穿透构件相对于穿透构件上游的压力下游的压力降低。 根据本发明的方法,消除了流量的独立性,而与使用的设备无关,其中流体经由分离的流动路径被供给到收集点,并且至少一个穿透构件被布置在每个流动路径内,导致减少 穿透构件相对于穿透构件上游的压力下游的压力。 流体最终在收集点收敛。

    • The present invention relates to a device (2) for the administration of fluids to a human or animal body comprising a housing (3) with a first inlet (28), at least one second inlet (29, 30), one outlet (31) and a collecting point, wherein the first inlet (28) communicates with the collecting point through a first channel and the outlet (31) communicates with the collecting point. The device is characterized in that the second inlet (29, 30) communicates with the collecting point or an indicator chamber (24, 25) through a second channel (21, 22) in which a valve (26, 27) is arranged, the valve (26, 27) being adjustable between a first position and a second position, wherein, in the first position of the valve (26, 27), the second channel (26, 27) communicates with the indicator chamber (24, 25) and, in the second position of the valve (26, 27), the second channel (21, 22) communicates with the collecting point. With the device (2) according to the invention, flow rate irregularities are eliminated (over shoot) or at least minimized (time delay, flow rate fluctuations due to changing flow rates), such that the device (2) allows for a more precise dosage.
