Section view of A-clamp-, yoke- or Int-valve to regulator connection, showing the sealing surfaces, according to ISO 12209-3 The yoke connector, also known as an A-clamp or international connector, is a component of the regulator that fits around the valve body at the outlet and presses the outlet O-ring of the valve against the inlet seat of ...
The hot water supply hose of the umbilical is commonly 1 ⁄ 2 inch (13 mm) bore, and is connected to a supply manifold at the right hip of the suit with a set of valves which allow the diver to control flow to the front and back of the torso, and to the arms and legs, and to dump the supply to the environment if the water is too hot or too ...
There are umbilical cord clamps which incorporate a knife. These clamps are safer and faster, allowing one to first apply the cord clamp and then cut the umbilical cord. After the cord is clamped and cut, the newborn wears a plastic clip on the navel area until the compressed region of the cord has dried and sealed sufficiently.
For shallow water surface supply air diving, the diver's umbilical is typically a 3-part umbilical comprising a 3 ⁄ 8 inch (9.5 mm) bore breathing gas hose, 1 ⁄ 4 inch (6.4 mm) bore pneumofathometer ("pneumo") hose, and diver communications cable, which usually also serves as a lifeline strength member. The pneumo hose is open at the diver ...
The ability to attach, remove and replace cylinders while in the water allows the diver to avoid carrying twinned cylinders. The reduced physical exertion when conducting regulator shut-down procedures is a major benefit to divers who suffer from shoulder or back discomfort or reduced mobility.
There are two aspects of umbilical management: By the diver, and by the attendant. They work together to keep the umbilical from twisting, restraining the diver's movements, entanglement, and excess slack. The tender will control the amount of umbilical in the water, recover excess slack and coil it ready for further use.
The Umbilical cord stump, left behind after omphalotomy. Omphalotomy is the medical procedure that involves the cutting of the umbilical cord after childbirth. [1] The word omphalotomy is derived from the prefix omphal(o)-, from the Ancient Greek word ὀμφαλός (omphalós), meaning navel, and the suffix-tomy, also from Ancient Greek, meaning incision.
To prevent hypothermia, hot-water suits are commonly used for saturation diving, and the breathing gas supply may be heated. Heated water is produced at the surface and piped to the bell through a hot-water line in the bell umbilical, then is transferred to the divers through their excursion umbilicals.
