摘要：
Abstract AspiratorThe invention relates to medical engineering, in particular to aspirators used, for example, in surgery, gynecology, physiotherapy for suctioning fluids from organs cavities.Object of the proposed utility model, is to expand the range of low pressure values, and thereby provide a wider field of application.The solution of this problem is provided by the fact that the aspirator comprising a vacuum pump connected to the power supply circuit with a switch, the pressure vessel, a collecting vessel and a pressure regulator according to the utility model, the pressure regulator is configured in the form of an electronic system is an electronic pressure regulator comprising multi setpoint pressure, and a pressure sensor, a differential amplifier, a pressure indicator receptacle, a comparator and a switch for switching on / off the vacuum pump, wherein multiposition pressure vessel is configured to set the required pressures, a pressure sensor configured to generate a signal proportional to the pressure in the collecting vessel and is connected through a differential amplifier to an indicator of pressure and a comparator connected to the pressure setting element and the relay for inclusions / vacuum pump outages.The proposed aspirator has a compact and robust design with an increased service life, as well as the wide range of applications.
