Abstract: The present invention relates to a motor-driven suction pump and a method for connecting such a pump. The suction pump has a pump unit for generating a negative pressure which is accommodated in a housing. Further, a terminal box is provided which can be connected to a power source via a connecting cable and has contact elements for supplying the pump unit with a power current. The contact elements are electrically conductively connected to the contact counter elements provided on the housing side and leading to the pump unit when the terminal box is coupled to the housing. In order to increase electrical safety, a sensor, an evaluation unit, and a switch are provided. The sensor is configured to check the coupling of the terminal box. The switch switches a power supply to at least one of the contact elements.

Abstract: A suspension device for a drainage container has, on a first side, a first fastening unit for mounting and fastening the drainage container on the suspension device. On a second side, a second fastening unit is present for mounting and fastening the suspension device on a rail. The first fastening unit is arranged in a first fastening part, and the second fastening unit is arranged in a second fastening part. The suspension device further comprises a weighing part with a weighing element, wherein the weighing part is connected or can be connected to the first fastening part and to the second fastening part so as to measure, with the weighing element, a relative displacement, such that a filling quantity of the aspirated body fluid in the drainage container can be determined.

Abstract: A medical suction pump for aspiration of bodily fluid has a suction pump housing, a fluid collection container held releasably on the housing, and at least one filling level sensor. The fluid collection container has a first side wall and at least one further side wall which together delimit at least one interior space for receiving the aspirated fluid. The at least one filling level sensor extends at least approximately parallel to the first side wall over at least a partial area of the fillable height of the interior space. The first side wall is place at least in part, and the cross section of the at least one interior space tapers vertically from the top downwards, at least over a partial area of the fillable height.

Abstract: A drainage pump unit for aspirating body fluids by means of a suction pump has a suction pump arranged in a suction pump housing, wherein a fluid collection container can be secured releasably on the suction pump housing, and wherein a capacitive filling level sensor is arranged on the suction pump housing for detecting a filling level in the fluid collection container. The filling level sensor has at least two electrodes, which are arranged at a distance from each other and extend along a common path. A first of the electrodes is in one piece, and a second of the electrodes is segmented. This arrangement permits the production of inexpensive fluid collection containers while still ensuring a high degree of measurement accuracy.

Abstract: A drainage pump unit for aspirating body fluids comprises a suction pump housing and a suction pump arranged in the suction pump housing. A fluid collection container can be secured releasably on the suction pump housing. A flat band-shaped capacitive filling level sensor is arranged on the suction pump housing for the purpose of detecting a filling level in the fluid collection container. The drainage pump unit also comprises an elastically configured coupling element with a first surface and a second surface lying opposite the first surface, and the coupling element, in the secured state of the fluid collection container, bears with the first surface on the filling level sensor and with the second surface on an outer wall of the fluid collection container. By virtue of the elastically configured coupling element, this drainage pump unit permits a filling level measurement even in the case of low filling amounts.
