DETAILED DESCRIPTION
[0039] Preferred embodiments are described below on the basis of the Figures. Here, features and characteristics are described by way of example for individual embodiments. It should be explicitly mentioned that features described here are not limited to the respective embodiment.
[0040] FIG. 1 shows a medical fluid pump 2 according to a preferred embodiment. The medical fluid pump 2 shown in FIG. 1 is designed as an infusion pump. Naturally, the medical fluid pump may also be configured as a syringe pump. As shown in FIG. 1, the medical fluid pump 2 has a substantially cuboid housing 4, on the front side of which is a front flap 6 pivotably hinged to the housing 4. A plurality of operating buttons 8, a plurality of signal lights 10, and a touch display 12 are arranged on a front side of the front flap 6.
[0041] The housing 4 further comprises an upper housing shell 14 and a lower housing part 16, which can be connected to each other and thus form the housing 4. A carrying handle 18 in the form of a handle bar is pivotably hinged to the upper housing shell 14. The carrying handle 18 embraces the upper housing shell 14 in a width direction, so that the carrying handle 18 is hinged to both side surfaces or to a first side surface and a second side surface of the upper housing shell 14 or of the housing 4, respectively. The carrying handle 18 is connected to the housing 4 at pivot points 20. The pivot points 20 are configured as hinges and are located, as shown in FIG. 1 and FIG. 2, substantially centrally in a longitudinal pump direction. The longitudinal pump direction is to be understood as a direction starting from the front side with the front flap 6 to a rear side of the medical fluid pump 2 opposite the front side. When the carrying handle 18 is folded out from the storage position into a carrying position, the carrying handle pivots about the pivot points 20. The axis of rotation thus passes through the pivot points 20.
[0042] FIG. 2 is an illustration of a side view of the medical fluid pump 2. In the upper housing shell, upper latching rails 22 are configured in the first side surface and the second side surface. In the lower housing shell, lower latching rails 24 are configured in the first side surface and the second side surface. The lower latching rails 24 of a first medical fluid pump 2 are provided and configured to engage the upper latching rails of a second, identically-constructed medical fluid pump 2 and to couple the first medical fluid pump 2 and the second medical fluid pump 2 together.
[0043] In FIG. 1 and FIG. 2, the medical fluid pump is shown in a state in which the carrying handle 18 is folded in and rests against the upper housing shell 14. In the folded state, the carrying handle 18 is flush with the side surfaces.
[0044] As shown in FIG. 3, according to the preferred configuration example, three medical fluid pumps 2 can be stacked on top of each other, connected/coupled together, and can be carried by the carrying handle 18 of the uppermost medical fluid pump 2. That is, the carrying handle 18 of the medical fluid pump 2 is configured and dimensioned to carry a combination of three medical fluid pumps 2 coupled together. The carrying handle 18 of the uppermost medical fluid pump 2 shown in FIG. 3 is in the carrying position. According to the invention, a respective center of gravity of the medical fluid pumps is in a substantially vertically arranged plane with the carrying handle 18. The housing 4 is oriented substantially horizontally in the carrying position. The carrying handle 18 is oriented substantially vertically in the carrying position.
[0045] FIG. 4 shows the inner structure of the medical fluid pump 2 according to the disclosure in the form of a syringe pump 26. The syringe pump 26 includes a drive train 28, which is provided and configured to include a holding arm 30, at the end of which a drive head 31 is provided that can be moved linearly with respect to the housing 4. The drive train 28 is configured in a first longitudinal half ELH of the housing 4 facing the front side of the housing and thus the front flap 6. A power adaptor 32 is configured in a second longitudinal half ZLH of the housing 4. The second longitudinal half faces a rear side 34 opposite the front flap 6. Advantageously, the power adaptor 32 is configured to abut the rear side 34. This enables cooling ribs 36 to be provided on the rear side 34 of the housing 4. These cooling ribs 36 are provided and configured to cool the power adaptor 32. In addition to the power adaptor 32, a wireless communication module 38 is also provided and configured in the second longitudinal half ZLH. In particular, the wireless communication module 38 is arranged between the power adaptor 32 and the drive train 28. In other words, the wireless communication module 38 is arranged between the rear side 34 and the first longitudinal half ELH. The wireless communication module 38 is connected to a first antenna 40 and to a second antenna 42, wherein the first antenna 40 is provided and configured adjacent to a first side surface 44 of the housing 4. The second antenna 42 is provided and configured adjacent to a second side surface 46 of the housing 4. The first antenna 40 and the second antenna 42 are oriented orthogonally to each other. The distance between the first side surface 44 and the second side surface 46 corresponds to a multiple of a quarter or a multiple of a half wavelength, respectively, of the transmission frequency of the first antenna 40 and the second antenna 42. A motor 48 driving the drive train 28 is configured in a first transverse half EQH of the housing 4. The drive head 31 is adjacent to the second transverse half ZQH of the housing 4. An energy storage device 50 is configured between the wireless communication module 38 and the drive train 28. A main board 52 is disposed in a planar manner within the housing 4.

The drive train 56 is configured in the front side of the housing, and thus in the first longitudinal half ELH of the housing 4 facing the front flap 6. The power adaptor 32 is configured in the second longitudinal half ZLH of the housing 4. The second longitudinal half ZLH faces the rear side 34 opposite the front flap 6. Advantageously, the power adaptor 32 is configured to abut the rear side 34. This allows cooling ribs 36 to be provided on the rear side 34 of the housing 4. These cooling ribs 36 are provided and configured to cool the power adaptor 32. In addition to the power adaptor 32, a wireless communication module 38 is also provided and configured in the second longitudinal half ZLH.
