DETAILED DESCRIPTION
[0041] FIG. 1 shows a medical fluid pump 2 according to the disclosure with a housing 4, which includes a lower housing shell 6 and an upper housing shell 8. A front lid 10 is formed on a front side of the fluid pump 2, which is hinged to the lower housing shell 6 via hinges 11 in a foldable manner and which is provided and formed to contain an operating and display element 7 of the fluid pump 2. Feet 12 and a cover 14 of an energy storage compartment (20 in FIG. 2) are formed on an underside of the fluid pump 2 formed by the lower housing shell 6. The cover 14 is flush with the underside of the fluid pump 2. Cover caps 16 are formed on the cover 14.
[0042] FIG. 2 shows the medical fluid pump 2 in a state in which the cover 14 of the energy storage compartment 20 is open. The cover 14 can be/is attached to the fluid pump 2 via screws 18 or can be/is attached to the fluid pump 2 via screws 18 such that an opening of the energy storage compartment 20 is closed. The cover 14 includes, on an outer surface (a surface facing away from the energy storage compartment 20 in an assembled state), cylindrical depressions 21 that are provided and formed to receive the cover caps 16. In this case, the cylindrical depressions 21 are located above through holes 23 of the cover 14, through which the screws 18 are screwed in order to fasten the cover 14 to the fluid pump 2. The cover caps 16 prevent moisture and contaminants from entering an interior of the fluid pump 2 through the through holes 23 (see FIG. 7). The energy storage compartment 20 includes a circumferential sealing rim/sealing surface 22 and threaded holes 24 into which the screws 18 can be screwed. An energy storage 25 is provided and formed to be inserted/insertable into the energy storage compartment 20.
[0043] FIG. 3 shows a detailed view of the underside of the lower housing shell 6 with the opening of the energy storage compartment 20 and the removed energy storage 25. In a preferred embodiment, the energy storage 25 is an accumulator which, when the fluid pump 2 is connected to a mains voltage supply, is charged with mains voltage and, when the fluid pump 2 is disconnected from the mains voltage, supplies the fluid pump 2 with energy. Preferably, the energy storage is constructed of a plurality of energy storage elements 26 and is connected to the electronics of the fluid pump 2 via a supply connector 28. Preferably, the energy storage compartment 20 is arranged in the fluid pump 2 in such a way that the energy storage 25 in an installed state extends larger/wider in a direction normal to the underside of the fluid pump 2 than in the direction of the underside of the fluid pump 2.
[0044] FIG. 4 shows a detailed view of the underside of the lower housing shell 6 with the opening of the energy storage compartment 20. In the direction of the front lid 10, the energy storage compartment 20 has a recess 30. On the side facing away from the front lid 10, the energy storage compartment 20 has a cutout 31. The recess 30 and the cutout 31 ensure that air reaches the sides of the built-in energy storage compartment 25 and thus keeps the energy storage compartment 25 air-cooled. In addition, the recess 30 facilitates removal of the installed energy storage 25.
[0045] FIG. 5 shows a top view of the energy storage compartment 20 of the fluid pump 2. The energy storage compartment 20 has an energy-storage receiving portion 32, which is formed on the side of the energy storage compartment 20 facing away from the opening of the energy storage compartment 20. The energy-storage receiving portion 32 is provided and formed to receive the energy storage 25. Preferably, the shape of the energy-storage receiving portion 32 is adapted to the contour of the energy storage 25. The energy storage compartment 20 has a notch 34 that is provided and formed to receive the supply connector 28 that connects the electronics of the fluid pump 2 to the energy storage 25.
[0046] FIG. 6 shows an internal view of the lower housing shell 6 of the medical fluid pump 2 according to the disclosure. The energy storage compartment 20 is formed in one piece with the lower housing shell 6 and extends substantially normal to the lower housing shell 6.
[0047] FIG. 7 shows the cover 14 of the energy storage compartment 20, in particular an inner side of the cover 14 of the energy storage compartment 20. The inner side of the cover 14 is to be understood as the side that is oriented towards the interior space of the fluid pump 2 in a state in which the cover 14 is mounted on the fluid pump 2. On the inner side, a seal 36 is provided and formed circumferentially to seal the cover 14 against the sealing rim 22 of the energy storage compartment 20 in a mounted state. Furthermore, buffer elements 38 are provided and formed on the inner side. The buffer elements 38 are preferably foamed buffer elements 38 in the form of foam beads. When the cover 14 is screwed against the housing 4 of the fluid pump 2 via the screws 18 through the through holes 23, the seal 36 is pressed against the sealing rim 22 to form a seal. Furthermore, the buffer element 38 is pressed/clamped against the energy storage 25 in a mounted state and fixes the energy storage 25 between the cover 14 and the energy-storage receiving portion 32. Thus, the energy storage is prevented from slipping in the energy storage compartment 20 and the buffer element 38 protect the energy storage from mechanical stress. The depressions 21 are supported via struts 39 in the direction of the circumferential seal 36. In particular, the struts 39 are oriented in the direction of the corner sections of the circumferential seal 36. This ensures that the screws exert a uniform force, in particular in the corner sections of the circumferential seal 36, and further impedes the penetration of liquids.
