DETAILED DESCRIPTION
[0032] FIG. 1 shows a medical fluid pump according to the invention, in particular a syringe pump 2. The basic mode of operation of the syringe pump 2 is sufficiently described in EP0566825A1, so that a detailed description of the syringe pump 2 is omitted here.
[0033] The syringe pump 2 shown in FIG. 1 includes a housing 4 with a lower housing shell 6 and an upper housing shell 8. A drive head 10 is connected to the syringe pump 2 via a holding arm 12 (see FIG. 3) so that it can move relative to the housing 4. A front lid 14 is provided and formed on the front side of the syringe pump 2. The front lid 14 is foldably hinged to the lower housing shell 6 via hinges. The syringe pump 2 is an exemplary example of a medical fluid pump. The present invention is also applicable to other medical fluid pumps, such as a peristaltic pump.
[0034] FIG. 2 shows a perspective view of the upper housing shell 8 of the housing 4 of the medical fluid pump according to the invention. In a mounted state, the upper housing shell 8 is in contact with the lower housing shell 6 via the contact rim 30. A printed circuit board 16 is provided and formed to be fixed via screws 18 to support members 20, which are preferably formed in one piece with the upper housing shell 8. The printed circuit board 16 has through holes 22, each of which is penetrated by a drive support member 24, which is provided and formed to have a drive fixed thereto in a force-fit and/or form-fit manner. A height of the drive support member 24 is greater than a height of the support member 20, each with respect to an inner surface 26 of the upper housing shell 8. The printed circuit board 16 includes a control device 28 of the medical fluid pump. In a mounted state, the printed circuit board 16 is spaced apart from the contact rim 30 in a direction normal to the printed circuit board. In other words, the printed circuit board 16 is spaced from the lower housing shell 6 in a mounted state.
[0035] FIG. 3 shows the upper housing shell 8 of the housing of the medical fluid pump according to the invention in a top view. In FIG. 3, the upper housing shell 8 is shown in a state in which the drive, consisting of a motor 32, a transmission 34 and a drive spindle 36 are fixed in the upper housing shell 8. In addition, a power adapter 38 is fixed to the upper housing shell 8. The power adapter 38 is preferably fixed to a portion 40 of the upper housing shell 8, which is oriented perpendicular to the printed circuit board 16. The motor 32, transmission 34, drive spindle 36, and power adapter 38 are preferably fixed in the upper housing shell 8 via screws 18. The screws 18 are preferably screwed into the drive support members 24. In addition to the drive support member 24 and the support member 20, further support member elements may be provided and formed to fix individual components or assemblies to the upper housing shell 8 at a distance from the lower housing shell 6 and preferably at a distance from the upper housing shell 8. Additionally, a communication module 42 is attached to the upper housing shell 8. The communication module 42 is preferably a wireless communication module, but may also be formed as a wired communication module that communicates information and data processed in the control device 28 located on the printed circuit board 16.
