Obstetrical amniotic fluid detection sampling device

Abstract

The invention relates to the technical field of medical instruments, in particular to an obstetrical amniotic fluid detection sampling device. The obstetrical amniotic fluid detection sampling devicecomprises a base, wherein a lifting assembly is fixedly connected to the top face of the base; the top of the lifting assembly is transversely bent; the other end of the lifting assembly is rotationally connected with a supporting plate; a connecting rod is spherically hinged to the other end of the supporting plate; the other end of the connecting rod is fixedly connected with a driving mechanism; the outer end of the driving mechanism is fixedly connected with a puncture needle; the driving mechanism is fixedly connected with a catheter communicating with the puncture needle; the other end of the catheter is fixedly connected with a sampling mechanism; and the sampling mechanism is fixedly connected with the driving mechanism. The amniotic fluid detection sampling device completes semi-automatic amniotic fluid sampling, is convenient and fast, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an obstetric amniotic fluid detection and sampling device. Background technique [0002] The fluid filled in the amniotic cavity is called amniotic fluid. The source, amount and composition of amniotic fluid vary with the gestational age. In the early stages of pregnancy, amniotic fluid is mainly the dialysate from the maternal serum passing through the placenta into the amniotic cavity, and a small amount from the surface of the placenta and the umbilical cord. Surface exudation, when the fetal blood circulation is formed, the water and small molecules in the fetal body can leak out through the unkeratinized fetal skin to form part of the amniotic fluid. The fetal kidneys have excretion function at 11 to 14 weeks of pregnancy, so the fetus after the second trimester The excreted urine is an important source of amniotic fluid. During full-term pregnancy, the amount of amn...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned shortcomings existing in the prior art, the present invention provides an obstetric amniotic fluid detection and sampling device, which can effectively solve the problem that the current sampling of amniotic fluid detection is mostly manual sampling, the operation is unstable, and it is easy to affect the fetus or pregnant woman. It is necessary for medical staff to hold and fix the sampling needle all the time, which will cause laborious problems in the sampling process
