My present invention in" the c nature of a' pumplng' device adapted fOrvariOusdif- I I ferent uses,but particularly designed for use inhospitals' and sick rooms, or physicians i P mp;
offices. The pump has devices adapting it'to operate'at will as a'vaeuum pump, as ap'resor' as a pulsator or device for producing pressure pulsations. W hen adjusted to act as apressure'pulsator,the device isadapted for use as a breast pump;
when adjusted forfaction as a vacuum pump, a it is adapted for use generally for the'production of vaouumlor for drawing fluids such as surplus blood during operations and when adjusted for adapted for [or an air-blowing action is desired;
