Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a ruptured membrane amniotic fluid collector for obstetrics and gynecology. Background Art

[0002] Spontaneous rupture of membranes is an important clinical manifestation of the first stage of labor, while artificial rupture of membranes is a more common method in labor. The main purpose is to release endogenous prostaglandins through artificial rupture of membranes, promote uterine contraction, accelerate the progress of labor, understand the properties of amniotic fluid, and determine whether the fetus has the possibility of intrauterine hypoxia. Therefore, artificial rupture of membranes is more common in labor.

[0003] The utility model patent, CN 214049029 U, discloses a clinical amniotic fluid sampling device for gynecological and obstetrical use. The device comprises a sampling tube, one end of which is provided with a rupture needle, a protective sleeve with multiple scales around the sleeve, a piston within the tube, an external thread on the other end, a threaded sleeve with a block at one end, a fixing sleeve with a slot at one end, and a storage tube below the tube. The protective sleeve is provided with first and second clamping plates, one end of the second clamping plate with two fixing blocks, one end of the first clamping plate with a pin, and a handle below the second clamping plate. The protective sleeve prevents medical personnel from injuring the mother's vagina during rupture of the membranes, further protecting the fetus. The first and second clamping plates secure the protective sleeve, providing greater stability for medical personnel during sampling.

[0004] However, there are still some shortcomings in the above structure. The above structure is operated by a single handheld structure, so it is easy to cause arm soreness and shaking if it is used for a long time, which can easily affect the work of collecting amniotic fluid.

[0046] Step 1: When using, you can choose to install it on the bed 1 or operate it by hand according to your needs, as follows:

[0047] (1) Install on the bed 1, then clamp the outer sleeve 3 by the cooperation of the clamp 2 36, the connecting block 2 37 and the fixing bolt, then the bottom of the mounting block 29 passes through the opening 30 on the bed 1, then turn the fastening bolt 31 by the handle 32, then the fastening bolt 31 moves into the opening 30 and presses against the mounting block 29 to form a fixation, then turn the handle 1 22 to drive the internal threaded sleeve 1 21 to rotate, so that under the cooperation of the thread and the limiting slider 1 23, the semi-threaded hollow cylinder 4 The membrane rupture needle 6, the hollow block 1 7 and the multiple liquid extraction tubes 8 are driven to move and then inserted into the pregnant woman's body. Then, the corresponding vacuum pump 17 is turned on, so that the air in the storage cylinder 9 can be extracted through the cooperation of the suction tube 18, the connecting tube 3 20 and the exhaust tube 19.
