DEVICE FOR SUCTION OF LIQUIDS AND/OR PARTICLES FROM BODY ORIFICES

摘要

The invention relates to a device for suction of liquids and/or particles from body orifices, wherein the device comprises a suction channel (16) through which the liquid and/or particles can be aspirated and a vacuum pump (14) for generating an underpressure in the suction channel (16). The suction channel (16) is provided with an opening for supplying additional air for adjusting the underpressure, wherein the volume flow of this additional air is adjustable via an additional air adjustment unit (24). Further, the device (10) has a manually operable adjustment unit (26) for adjusting the additional air adjustment unit (24), wherein the adjustment of the adjustment unit (26) in each case by a same preset adjustment way effects in each case the same change in the underpressure.

1. A device for suction of liquids and particles from body orifices, comprising
a suction channel through which the liquid and/or the particles can be sucked, a vacuum pump for generating an underpressure in the suction channel for suction of the liquid and/or the particles, wherein the suction channel is provided with an opening for supplying additional air for adjusting the underpressure, an additional air adjustment unit for adjusting the volume flow of the additional air supplied to the suction channel, and a manually operable adjustment unit for adjusting the additional air adjustment unit, wherein at least in the range between a lower limit value of the underpressure and an upper limit value of the underpressure the adjustment of the adjustment unit in each case by a same preset adjustment way effects the same change in the underpressure , and in that the adjustment unit is continuously adjustable.
