Amniotic fluid sampling device for obstetrics and gynecology examinations

Abstract

The invention relates to the technical field of obstetrics equipment, in particular to an amniotic fluid sampling device for obstetrics and gynecology examinations. The amniotic fluid sampling deviceincludes a mounting plate, an adjuster and a sampling needle; the mounting plate is arranged above the mounting plate, the peripheral side of the adjuster is fixedly connected with the mounting platethrough a plurality of supports, the adjuster is of a barrel structure with a hollow interior, a screw rod is rotatably installed inside the adjuster, a screw sleeve is slidably installed inside the adjuster, and the screw rod and the screw sleeve are in threaded connection; and the screw rod and the screw sleeve are each of a hollow structure, and the sampling needle communicates with the interior of the screw sleeve through a connection pipe. When the amniotic fluid sampling device for the obstetrics and gynecology examinations is in use, a doctor turns a knob to drive the screw rod to rotate, then, the position of the sampling needle is adjusted, thus, the sampling needle slowly stretches into the body of a parturient, and the situations are avoided that the sampling needle stretches into the body of the parturient too rapidly, and the portion, stretching into the body of the parturient, of the sampling needle is too long; and subcutaneous cells which do not belong to an amniotic fluid are prevented from being brought into the amniotic fluid, and the purity of the amniotic fluid is ensured.

Description

technical field [0001] The invention relates to the technical field of obstetrical equipment, in particular to an amniotic fluid sampler for obstetrics and gynecology examination. Background technique [0002] In the field of obstetrics and gynecology, regular sampling of maternal amniotic fluid can effectively determine the health status of the fetus and mother, timely discover hidden diseases and carry out corresponding treatment, and generally carry out regular amniotic fluid sampling testing for the health status of the mother and fetus, so that Effectively determine the health status of the fetus. However, when amniotic fluid sampling is currently performed, in many cases it is only done by needle puncture. It is easy to bring subcutaneous cells that do not belong to the amniotic fluid into the amniotic fluid during puncture, which will affect the amniotic fluid. The degree of purity is very inconvenient, and it is easy to cause infection, and the extracted amniotic flu...

However, when amniotic fluid sampling is currently performed, in many cases it is only done by needle puncture. It is easy to bring subcutaneous cells that do not belong to the amniotic fluid into the amniotic fluid during puncture, which will affect the amniotic fluid. The degree of purity is very inconvenient, and it is easy to cause infection, and the extracted amniotic fluid is not specially preserved, which affects the accuracy of inspection and analysis, resulting in very troublesome amniotic fluid inspection work, and the extraction device only has a single function
