A two-part, hand held foetal blood sampling probe 2 enables rapid determination of foetal stress during labour. The two-part probe encompasses a sterile disposable sensing probe 6 containing a pH sensor 10 and lancet 8 attaching to a monitor 4 housing the hardware, software and user interface. The two parts 4 and 6 combine to form a small single foetal probe 2 capable of determining pH levels at small maternal cervical dilatations. The foetal probe may be used to determine analytes such as: pO2, pCO2, Na, Cl and K of a foetal blood sample. The reusable monitor may comprise lancet control means and a display for showing the resulting analysis of an analyte present in the blood sample. The disposable sensing probe may comprise a lancet to secure a blood sample from a foetal scalp, integral fluidics for transporting the blood sample for analysis and an integral sensor for effecting analysis and providing a result relating to an analyte present in the blood sample. The disposable sensing probe may also comprise integral heating means for maintaining the temperature of the blood sample at a desired level. |
