When comparing the 6a / 6b with the 7a / 7b it can be seen that by a movement of the drive unit 16, a relative movement between the tube assembly 24 / 25 As well as the valve assembly 23/27 has shown, since the valve assembly 23/27 in the region of the protective tube 27 by a on the housing 13 arranged clamp holder 18 (S. 2 ) is held. The container 12.2 is also a hose line 30 that has a flow channel 26 having intermediate piece 25 , the tube 24 as well as the hose line 28 connected to a syringe 17, the stored in the container 12.2 medical component in the desired amount to the infusion bag 11 feeds.

At the same time is in the viewing window 37 of the protective tube 27 to recognize a corresponding with the outer clamping body 35.2 graphic structure 36.2. This allows the operator of a device 10 at a glance each recognize that from the container 12.2 a medical component just the infusion bag 11 is supplied.

The 8th and 9 each show an enlarged sectional view of the in 7b marked with VIII, the section according to 8th corresponds to the drawing 7b, while the sectional view according to 9 Although in the 7b marked with VIII, but has a different sectional plane.

In the synopsis of 8th and 9 you realize that the intermediate piece 25 a clamping projection 38 which is in the left tube 24 engages and another clamping projection 39 (S. 9 ), which is in the right tube 24 intervenes. Through the intermediate piece 25 thus becomes a stable connection between the two tubes 24 achieved, wherein the clamping projection 39 the already described flow channel 26 provides.

Especially in the 8th is also the type of connection of the individual valve body 23.1 - 8 with each other and also with the thermowells 27 to recognize. Thus, each valve body 23.1-8 has a tubular projection 40 on the one hand and on the opposite side an annular cavity 41 on, wherein in each case the tubular projection 40 clamped in the annular recess 41 is introduced. The same applies to the protective tubes 27 which has a tubular projection 42 have, in the annular cavity 41 of the valve body 23.1 (s. 8th ) is arranged clamped.

In the event that two consecutive the infusion bag 11 supplied medical components could chemically react with each other, it is possible in an intermediate step from a container 12 First, a rinse solution for a certain time the infusion bag 11 To ensure that in the supply line to the infusion bag 11 no remnants of the previous medical solution are left.

In addition, it is also important that regardless of which position the multiple valve arrangement 22 is, the dead volume, that is, the volume located in the supply lines always remains constant, as in certain positions of the multiple valve assembly 22 the hose line 28 also in the upper tube 24 can be drawn in. This is for an accurate automatic dosage of the portions for the infusion bag 11 very important.
