Description

Clinical integrative device of rupture of membranes amniotic fluid sample of using of gynaecology and obstetrics

Technical Field

The utility model relates to the technical field of medical devices, in particular to a membrane rupture and amniotic fluid sampling integrated device for clinical use in obstetrics and gynecology department.

Background

Amniotic fluid puncture examination is a prenatal diagnosis method, and is generally suitable for prenatal diagnosis of mid-term pregnancy. The amniotic fluid puncture is a process of penetrating a slender needle through the belly skin and the uterine wall of a pregnant woman under the guidance of ultrasonic waves, entering a amniotic fluid cavity and extracting some amniotic fluid, which is called as amniotic fluid puncture. Amniotic fluid exists in the amniotic cavity, fertilized eggs form the amniotic cavity on the seventh day of fertilization, amniotic fluid is generated, the amniotic fluid amount is 50 ml at the 12 th week of gestation, 400 ml at the 20 th week and 1000-1500 ml at the 36-38 th week, and the amniotic fluid amount is slightly reduced near the predelivery period. The best puncture time for extracting amniotic fluid for prenatal diagnosis is 16-24 weeks of gestation. Because the fetus is small at this moment, the amniotic fluid is relatively more, the fetus floats in the amniotic fluid, the wider amniotic fluid belt is arranged around the fetus, when the amniotic fluid is extracted by puncturing with a needle, the fetus is not easy to be punctured, 20 ml of amniotic fluid is extracted, the amniotic fluid only accounts for 1/20-1/12 of the total amount of the amniotic fluid, the uterine cavity cannot be suddenly reduced to cause abortion, the proportion of viable cells in the amniotic fluid is maximum at this stage, the cell culture survival rate is high, the amniotic fluid can be used for flaking and dyeing, and can be used for chromosome karyotype analysis, chromosome genetic disease diagnosis and sex judgment of the fetus, and the DNA of amniotic fluid cells can also be used for making gene disease diagnosis and metabolic disease diagnosis. The alpha fetoprotein in the amniotic fluid is measured, and the open neural tube deformity of the fetus can be diagnosed.

A large number of searches find that: chinese utility model patent: the utility model discloses an application number (CN 201120196288.6) and a publication number (CN 202235465U), and discloses a trace amniotic fluid puncture extraction device, which comprises: a guiding unit including a guiding needle; the extraction unit comprises an extraction needle and a storage device, and the tail part of the extraction needle is connected with the storage device; the inducing needle sleeve is arranged outside the suction needle.

A large number of searches find that: the Chinese utility model patent: the application No. (CN 201922139366.8), publication No. (CN 211460292U), the utility model discloses a negative pressure amniotic fluid piercing depth, and the utility model relates to amniotic fluid puncture inspection technical field, including the needle tubing, the internally mounted of needle tubing has the piston, and the top of piston installs the piston rod, the disc is installed on the top of piston rod, the hose is installed to bottom one side of needle tubing, and installs the solenoid valve in one side of hose, the micropump is installed to the one end of hose, and one side of micropump is installed and is held the bag, the fixation clamp is installed to the outer wall of needle tubing, and installs the switch in one side of fixation clamp, electric telescopic handle is installed to one side of fixation clamp, and the power cord is installed to one side of electric telescopic handle.

But the amniotic fluid puncture device who uses at present only can extract the sampling to the amniotic fluid when using, place the amniotic fluid of extraction in storage device after the sampling is accomplished again, consequently use convenient inadequately, simultaneously, in the sampling process, because patient's belly thickness differs, the degree of depth that leads to the needle tubing to pierce at every turn is different, this requires highly to doctor's experience, and lead to the sampling process to have certain risk, consequently need an integrative device of clinical rupture of membranes amniotic fluid sampling of gynaecology and obstetrics to solve above-mentioned problem.
