Style and design and dimensions. The reservoir shall be an oval-shaped aspirator bulb with a permanently attached semi-rigid silicone rubber head. The reservoir head shall have a drainage port, a suction port, and an attached bulb strap. The suction port shall have a plug attached to it which makes a mechanically secure and leak-proof connection with the drainage port.

The suction port shall protrude from the reservoir head 0.562 � 0.005 inches.� The suction port shall have three steps ranging in outside diameter from 0.156 � 0.007 inches at the top of a step to 0.187 � 0.007 inches at the base of a step. The top step shall be 0.16 � 0.01 inches in length, with the top of the first step forming the distal tip of the suction port. The second and third steps shall be 0.15 � 0.01 inches long. The drainage port plug shall be attached to the suction port between third step base and the reservoir top. The suction port shall have an inside diameter of 0.110 � 0.007 inches. The suction port shall connect to an integral Bunsen valve on the interior of the reservoir which allows flow of fluids into the reservoir but prevents flow from the reservoir into the suction port. The Bunsen valve shall also prevent the loss of negative pressure in the suction tubing when the reservoir drainage port in opened.

The reservoir drainage port shall protrude from the reservoir head 0.250 � 0.020 inches, shall have an inside diameter of 0.156 � 0.010 inches, and shall have an outside diameter of 0.219 � 0.01 inches.
