Device for suctioning

Abstract

Abstract The suction device has a telescoping upper and lower casing and an interposed carrier director with fixtures attached for the purpose of controlling suction and the amounts of fluid allowed into the lower casing of the instrument, and depending on the controlled protrusion of the carrier-director, control of suction and fluid in the parts to be suctioned is obtained, as well as releasing unwanted parts that may be suctioned into the mouth of the instrument. Transmission of pressure to the carrier-director directly by pushing a knob on the proximal end of the carrierdirector or indirectly by pushing the upper casing which telescopes over the lower casing moves the carrier director by transmitting pressure over fixtures enclosing a spring on the carrier-director. A ring on the distal end of the carrierdirector is moved to slide over the u fluid inlet in the distal portion of the lower casing, thus stopping the flow into and out of the mouth of the lower casing, while a ball-like object attached to the lower end of the carrier-director is protruded away from the mouth of the lower casing thus allowing the transmission of suction to the parts suctioned. If unwanted parts are inadvertently suctioned to the opening of the lower casing, further protrusion of the carrier-director by direct pressure on the knob of the carrier-director moves the ring away from the fluid inlet, permitting fluid to enter the lower casing and flush the intruding portion away from the mouth of the device. Release of pressure on the carrier-director knob allows the continuation of suctioning of the body parts intended. Release of the upper casing closes off the device from the body and permits the inflow of fluid into the lower casing and continuation of suctioning of the matter taken into the device. Thus the suctioned matter is diluted and pressured out of the suction outlet on the upper part of the lower casing by the fluid. The spring tension having been released by release of pressure on the upper casing retracts the carrier-director and the attached ring and ball move away from the fluid inlet, respectively, and the ball occludes the mouth of the lower end of the device, thus continuous suction and dilution occur in the lower casing which has been closed off from the body parts.
