Problems solved by technology

However, at present, the sampling of amniotic fluid is mostly done manually, which is cumbersome to operate and requires medical staff to hold and fix the sampling needle all the time. This will lead to laborious sampling process, and it is easy for medical staff to control improperly, which will affect the fetus and pregnant women.

Abstract

The invention discloses an amniotic fluid detection and sampling device for obstetrics and gynecology. and the inner cylinder, the first connecting plate is connected with the bracket, the first motor is provided in the middle of the bottom surface of the first connecting plate, the output shaft of the first motor is sleeved with a connecting plate, the connecting plate is connected with the outer cylinder, and the inner cylinder is slidingly sleeved The bottom of the inner cylinder is connected with a sampling needle, and a piston is slidably arranged in the inner cylinder. The top of the inner cylinder is provided with a second connecting plate, and the second connecting plate is provided with a driving mechanism for driving the piston for sampling. The amniotic fluid output port; the end of the output shaft of the first motor is connected to the first lead screw, and the first lead screw is connected to the driving mechanism through the first threaded sleeve provided by sleeve. The invention has reasonable structure and simple operation, can realize controllable sampling in the process of amniotic fluid detection and sampling, and effectively guarantees the safety of pregnant women and fetuses in the sampling process.

Description

technical field [0001] The invention relates to a medical device, in particular to an amniotic fluid detection and sampling device for obstetrics and gynecology. 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 amniotic fluid ...
