Abstract: The present invention concerns a procedure and a device to determine the concentration of protamine-1 and protamine-2 and the ratio between protamine-1 and protamine-2 as protamine/protein ratio in a questionable sample from an individual to be examined in order to assess the fertility of the sperm in vitro. This assessment is of great importance for the prognosis of the success of an artificial insemination of an egg in vitro. The test strip comprises a sperm pretest to determine the sperm concentration and a protamine rapid test to determine the concentrations of protamine-1 and protamine-2 and the ratio between protamine-1 and protamine-2 as protamine/protein ratio.

Abstract: The present invention concerns a suspension device for free positioning of equipment in rooms used for medical purposes. Multiple open-profile links, comprising a central link (160) for attachment on an axis, intermediate links (150), and an end link (140) are serially connected to one another. Each profile of the links comprises at least one indentation (30). The indentations (30) of the profiles are configured for accommodation of a cable.

Abstract: A medical suspension system (10) includes a ceiling plate (30) configured for mounting to a support structure (16). The ceiling plate supports a device (12), such as a lighthead or video monitor, which is mounted to the ceiling plate via an articulated arm (50) and a spindle (40), which is centrally mounted to the ceiling plate. A second device (14) is mounted to the ceiling plate, not through the spindle (40), in the conventional manner, but via an adapter plate (62), which is mounted directly to the ceiling plate. This increases the number of devices which are readily carried by the support structure without extending the spindle length which conventionally occurs when additional hubs are added to the main spindle.

Abstract: A suspension system is disclosed for suspending lightheads, monitors, cameras, or other medical apparatus from an overhead structure at a selectable height. A drop tube has a selected portion thereof surroundingly encompassed by a receiving element that has a variable inside diameter substantially conforming to a frustum of a cone. A mounting plate rigidly connects with the overhead structure and with the receiving element. The mounting plate has an opening through which an end of the drop tube passes. A wedge-shaped element has an overall variable outer diameter substantially conforming to a frustum of a cone and includes a lower threaded tapered region. The wedge-shaped element compressively inserts into the receiving element through tightening of a nut on the threaded tapered region. The element surroundingly encompasses the selected portion of the drop tube to effectuate a compressive clamping of the selected portion of the drop tube inside the receiving element.
