Medical suction pump
A motorized medical suction pump has a pump assembly for generating an underpressure, a pump assembly carrier for supporting the pump assembly, and a seat for receiving an energy accumulator. The pump assembly arranged in the pump assembly carrier defines a first longitudinal axis, and the seat defines a second longitudinal axis. The pump assembly carrier forms the seat. The second longitudinal axis extends at an angle to the first longitudinal axis. This suction pump is small and compact and has good sound damping.
1. A motorized medical suction pump with a pump assembly for generating a vacuum, with a pump assembly carrier for supporting the pump assembly, and with a seat receiving an energy accumulator, wherein the pump assembly arranged in the pump assembly carrier defines a first longitudinal axis, and the seat and the energy accumulator define a second longitudinal axis, wherein the pump assembly has along the first longitudinal axis a first end and a second end, the first end and the second end being opposite ends, wherein the pump assembly carrier forms the seat, wherein the second longitudinal axis extends at an angle to the first longitudinal axis, and wherein exactly two bearings consisting of a first elastic bearing and a second elastic bearing are present for supporting the pump assembly in the pump assembly carrier, wherein the first elastic bearing is arranged at the first end of the pump assembly and the second elastic bearing is arranged at the second end of the pump assembly, wherein the pump assembly is arranged in a sound-damping housing, and the sound-damping housing is held in the pump assembly carrier, wherein the sound-damping housing is supported in the pump assembly carrier by means of the first elastic bearing and the second elastic bearing, and wherein the first elastic bearing and the second elastic bearing on the one hand support the sound-damping housing in a pump housing and on the other hand support the pump assembly inside the sound-damping housing.
