There are few practitioners who have not been annoyed at times with the inefficiency of the apparatus employed in exploratory aspiration of fluid accumulations. The needle is not of the desired size, or the piston does not fit the syringe tightly, or the glass barrel itself may break at the critical moment.
The simple device here figured suggested itself to me while witnessing an episode of instrumental treason; it seems to answer its purpose perfectly and relieves us of the tyranny of the exploratory syringe.1 In its use the muscles of the operator's mouth serve as the piston and the tip of his tongue as the valve of the syringe.
The construction of the apparatus should at once be clear from the diagram. The hollow needle a may be of any desired size. It is inserted in the piece of rubber tubing b. This tubing should have a narrow lumen
