    摘要: A hypodermic syringe has a tubular body extending along and centered on an axis and having an axially forwardly open front end, a piston rod axially displaceable in the body and having a plunger rod extending rearwardly from the body, and a plug fitted into the front end and forming an axially through-going passage. An elastomeric membrane is provided in the plug traversing and blocking the passage. Furthermore structure fixed to the plug includes a point in the passage spaced axially slightly forward of the membrane so that the membrane can be deformed axially forward to engage and be pierced by the point.

    摘要: A method of using cavitate- or clathrate-forming host/guest complexes for the preparation of contrast media in ultrasonic examination is provided. The host/guest complexes have a host which dissolves in a liquid carrier, releasing the guest (inert gas). With such contrast media, it is possible to diagnose blood and its flow conditions in the heart, and other organs, such as the myocardium, liver, spleen, and kidneys. Other internal systems such as the urinary ducts, the gastrointestinal tract, joints, and eyes can also be imaged.
