Problems solved by technology

[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 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

Embodiment 1

[0027] see figure 1 , 2 And 4, in the embodiment of the present invention, a kind of amniotic fluid sampler for obstetrics and gynecology examination, comprises installation board 1, adjuster 4 and sampling needle 10; The peripheral side is fixedly connected with the mounting plate 1 through several brackets 2. The regulator 4 is a hollow cylinder structure. The inside of the regulator 4 is installed with a screw 18 for rotation, and the inside of the regulator 4 is also slidably installed with a screw sleeve 20 and a screw 18. Threaded connection with the screw sleeve 20, the rotation of the screw rod 18 drives the screw sleeve 20 to slide up and down in the regulator 4; the screw rod 18 and the screw sleeve 20 are both hollow structures, and the sampling needle 10 passes through the connecting pipe 21 and the screw sleeve 20 The interior of the liquid storage tank 8 is fixedly installed on the support 2, and the liquid suction pump 7 is fixedly installed on the outside of t...

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.
