Specific embodiment
Embodiments of the present invention will be further described with reference to the accompanying drawing.
In general, general puerpera's production sequence is that amnion first ruptures, and amniotic fluid outflow, most of amniotic fluid can be preferential
Outflow will cause a small amount of blood outflow since placenta separates etc. with the uterine wall of puerpera later.But in the progress of labor,
It can occur to cause uterine wall rupture or colporrhexis generates bleeding abdominal pressure is excessively high, or even since site is not right, or
Other situations of person cause main blood vessel to burst, cause big bleeding or abdominal cavity hemorrhage.
In traditional parturient childbirth monitoring, the detection to blood pressure and heartbeat level is relied on, is judged indirectly by physical signs
The blood loss situation of puerpera, when puerpera's hypopiesia, heart murmur, carry out the rescues such as corresponding blood transfusion.But this method category
In post, cannot the lying-in woman during delivery of effective monitoring in real time blood loss.Need to rely on sentencing for obstetrician and nurse
Disconnected, this judgement needs certain experiences and attention.
The present invention analyze containing blood volume by amniotic fluid and watery blood mixture that puerpera is discharged, to judge the blood loss of puerpera
