#25132 - Die Cast Handle

#25135 - Stainless Steel Handle

#25141 - 30" Chain

#25146 - 60" Chain

SPECIFICATION: The obstetrical (OB) chains (#25141 & #25146 ) are USA manufactured from high quality nickel plated steel with twist links and are high tensile strength (1200 lbs). OB chains (#25140, #25142, & #25145) are manufactured of twist-link carbon steel and a zinc plated finish. The twist-link design aids in the prevention of slippage and damage to the animals’ legs. It also provides a snug grip for the handles when they are placed on the twist-links for leverage. The oversized oval links on each end of the chain are made of hard carbon steel for strength. The #25132 handle is constructed of die cast zinc and nickel plated. The #25135 handle is solid welded stainless steel including a modified vinyl grip that can be autoclaved. The stainless steel handle is a more durable material than zinc die cast. The choice of chain length is dictated by where the placement of the fetus is in the birth canal. The shorter length chain is best used when the front legs are exposed and the longer length if the fetus is displaced in the birth canal. The handle selection has no direct effect on the procedure and is user preferred.

OBJECTIVE: The OB chains and handles are utilized for aiding in the delivery of a fetus when assistance is required during birth.

APPLICATION: Feed the chain twist-links through the oval ends of the chain to form a loop which is placed snugly over the animals’ front feet above the hooves. The handle hooks are placed on the chain twist-links where they are the most convenient and comfortable for the birth assisted pull. Grasp the handles and firmly pull on the chain in conjunction with the animals’ uterine contractions. Pull firmly and smoothly but try to avoid extreme jerking and unnecessary pressure due to the possibility of injuring the fetus and/or the dam. Remove and thoroughly clean the equipment after the assisted birth is completed. It is best to consult a veterinarian for further information or assistance in most situations where there is a birthing difficulty.
