Device for suctioning

Abstract

Abstract The suction device incorporating the present invention has a telescoping upper and lower casing and an interposed carrierdirector with fixtures attached for the purpose of controlling suction and the amounts of fluid allowed into the instrument, and depending on the controlled amount of protrusion of the carrierdirector, control of suctioning and the amounts of fluid to the parts suctioned is obtained. Means of releasing unwanted suctioned matter is provided for in the device. The carrierdirector is hollow and carries fluid from a source into the distal end, the outlet is guarded by a t-tube which is occluded when the outlet is brought in contact with a hollow ring fixed to the lower casing. At the end of the carrier-director is a ball which occludes the opening of the lower casing at the distal end. Depending on the position of the ball relative to the mouth of the lower casing and the opening in the carrier-director to the fixed ring, the fluid flows readily when the opening of the ttube is not occluded. The constant suction applied to the outlet in the lower casing, is varied in effect by the relative position of the ball. When the ball occludes the mouth of the lower casing, the suction is applied only to the contents of the lower casing. When the ball is protruded a fixed distance when the upper casing meets a fixed obstacle on the lower casing, this distance is also the amount required to bring the t-tube into the ring thus shutting off inlet of fluid. The suction is now applied to the part to be suctioned. Further protrusion a fixed distance by pressure on a knob on the proximal part of the directorcarrier allows both suction and fluid to be applied to the part to be suctioned. Thus unwanted intrusion of a part being suctioned is pushed further away and is washed away by a flush of fluid following the release which occurs when the t-tube is pushed away from the lumen of the ring. When suction is desired to be continued in the part to be suctioned the pressure on the knob is released and a spring-like fixture on the upper end of the carrier brings the carrier director back to the position of the upper casing being compressed against the lower casing. If suction to the part of the organ being suctioned is desired to be interrupted, release of the pressure on the upper casing allows the carrier-director to return the position of the uncompressed spring-like device now suction is applied only to the suctioned material by reason of the lower casing being closed off from the part to be suctioned by the ball on the end of the returned carrier-director, and fluid flows freely to dilute the suctioned material and to pressure the material out of the suction egress tube. This occurs because the t-tube on the carrier-director is carried away from the ring, so the outlet of fluid is free.
