MEDICAL SUCTION DEVICE Russian patent published in 2011 - IPC A61M1/00 G01F23/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to suction devices for suction fluids from organ cavities. Device contains reservoir-collector with lid, under which installed is sensor of overflow, consisting of two electrodes, successively connected vacuum-pump, electric engine, device of electric engine control, pulse generator, transformer, first peak detector, second peak detector, first threshold device, second threshold device, OR element and diode. Reservoir-collector with lid is switched to outlet of vacuum-pump, outlet of pulse generator is switched to inlet of first peak detector, to inlet of second peak detector and to first lead of first transformer winding, second lead of first transformer winding is connected with circuit "general" of electric power, whose outlet is connected with first inlet of OR element, outlet of second peak detector is switched to inlet of second threshold device, whose outlet is switched to second inlet of element OR, whose outlet is connected with inlet of device of electric engine control. Device contains two electric connectors of "nest" type, each of which contains two electric contacts. On external part of lid installed are two metal pins, electrically connected with electrodes of overflow sensor, first lead of second transformer winding is connected to first contact of first electric connector, to whose second contact switched is diode cathode, second lead of second transformer winding is switched to first contact of second electric connector, to whose second contact switched is diode anode. Metal pins are introduced into electric connectors, performing closure of the first and second contacts of connectors and switching electrodes of overflow sensor to leads of second transformer winding.

EFFECT: application of invention will make it possible to increase reliability of medical suction device due to its constructive peculiarities of connector manufacturing.
