The UCC-V is used at the point in the third stage of labour where the cord is clamped and divided. That covers obstetric-led units, midwife-led units, community teams working from a packed bag, and theatre lists where a caesarean birth reaches the same step under different conditions. The working end is scaled to a newborn cord, the action is a single squeeze, and there is nothing to set up, so it is a short thing to teach and a short thing to check on arrival.
Timing is guided rather than instrument-driven. NICE holds that the cord should not be clamped before one minute from birth unless cord integrity is in doubt or the baby has a heart rate below 60 beats per minute that is not rising, and that clamping happens before five minutes, when controlled cord traction forms part of active management. A woman asking for longer is supported in that choice. The instrument is picked up at the end of that sequence and plays no part in setting it.
Community and home birth teams deserve a separate look. A bag is packed to a weight and a volume, and every item in it has to justify the space it occupies. A wholly mechanical instrument with no cell to go flat between call-outs, and no charge state to check before leaving, suits a kit that may sit in a car boot for weeks. In that setting, case quantity and packed size matter more than they do on a ward, and neither is published.
Procurement runs through the usual routes. NHS Supply Chain carries umbilical cord clamps under both general and sterile headings. Trusts, Integrated Care Boards and independent maternity providers each buy against their own framework and standing financial instructions.
Each route asks for conformity evidence early. The conformity documentation those procurement routes require is issued by the manufacturer and provided by the seller.
