Description
Technical Field
The utility model relates to a disposable amniotic fluid detection rod, in particular to a disposable amniotic fluid detection rod capable of measuring depth and displaying, belonging to the technical field of medical special examination articles.
Background
Amniotic fluid is a colorless and transparent alkaline liquid filled in the amniotic cavity. The origin, amount and composition of amniotic fluid vary from one gestational week to another, such as: in the early stage of pregnancy, amniotic fluid is mainly a dialysate which is formed by matrix serum entering a amniotic cavity through a placenta and a small amount of the dialysate seeps out of the surface of the placenta and the surface of an umbilical cord; after the blood circulation of the fetus is formed, water and small molecules in the body of the fetus can seep out through the skin of the fetus which is not yet keratinized to form a part of amniotic fluid; at 11-14 weeks of gestation, the kidneys of the fetus have excretion function, so urine discharged by the fetus after the middle term of gestation is an important source of amniotic fluid.
Premature rupture of the fetal membrane refers to natural rupture of the fetal membrane just before birth, and premature rupture of the fetal membrane at gestational age <37 gestational weeks is also called premature birth (preterm). Premature rupture of the fetal membranes is mainly characterized by sudden vaginal drainage caused by various reasons, and the drainage quantity can be more or less. The drainage is usually continuous and has different duration, the initial amount is large and then gradually reduced, and the few are intermittent drainage. Vaginal drainage is usually related to the change of body position and the movement of pregnant women. Premature rupture of fetal membranes is the most common complication in perinatal period, and can cause early yield increase, perinatal mortality increase, and intrauterine infection rate and puerperium infection rate increase. The reasons for premature rupture of membranes are: trauma, cervical internal orifice relaxation, infection, increased amniotic cavity pressure, poor connection between the fetal presenting part and the pelvic inlet, and fetal membranous dysplasia.
Since amniotic fluid is colorless alkaline liquid, when a pregnant woman suffers from premature rupture of the fetal membranes, the pregnant woman and family members may misunderstand the amniotic fluid as urine because the leaked liquid cannot be well distinguished from urine or amniotic fluid, and the pregnant woman cannot go to a hospital for professional diagnosis and treatment in time, so that the pregnant woman misses the optimal time point for timely finding and intervening of premature rupture of the fetal membranes.
Therefore, it is necessary to provide a tool for determining whether the leaked liquid is amniotic fluid in a timely and effective manner.
