Abstract: A resilient cover for a pinch clamp which fully encloses the clamp providing a smooth, snag free surface. The cover pads the clamp and softens the sharp edges of the clamp, providing an increased level of comfort for the patient using the clamp. The cover also provides an increased level of safety by reducing the likelihood of the clamp being inadvertently opened or closed. The cover closely surrounds the clamp, restricting outward movement of portions of the clamp such as the latch and tongue, reducing the chance of their being accidentally released. Internal nubs extend into the cavity holding the clamp and engage the face openings of the clamp. In addition to holding the cover in place, the nubs resist inward movement of the latch and tongue reducing the chance of the clamp being accidentally engaged. The cover is slit along one side so that it can be placed over the clamp with the clamp positioned on a tube. The slit passes through one or more of the nubs.

Abstract: In a method and apparatus for measuring sperm penetration in vitro through previously collected cervical mucus, a flat, transparent slide has one or more capilliary channels which will permit positive introduction of the cervical mucus to one end of each of the channels, and a sperm specimen is placed at the opposite end of each of the channels in direct communication with the cervical mucus in the channels. After incubation, the extent of penetration of the sperm cell specimens through each of the channels can be measured and compared.
