An obstetric amniotic fluid drainage device

Abstract

The invention discloses an amniotic fluid drainage device for obstetrics, which mainly includes a terminal head, a drainage middle frame, a middle tube, a side water suction seat, a diaphragm pump, a cover plate and an outer frame. Set the plunger. The present invention has a reasonable structural design. When the membrane is ruptured, the fetal membrane protrudes into the device, and the displacement range of the needle is also small, which will not cause damage to other parts. The built-in needle in the whole process ensures smooth rupture of the membrane and is safer; Absorb the overflowing amniotic fluid at regular intervals to avoid too much overflow and pollute the operating environment; the transmission parts of the device mostly use see-through components to ensure safe and visible operation.

Description

technical field [0001] The invention relates to a drainage device, in particular to a drainage device for obstetric ruptured amniotic fluid. Background technique [0002] Artificial membrane rupture is one of the methods commonly used in obstetrics to induce labor and induce labor. Membrane rupture can cause the amniotic fluid in the membrane to flow out and change the volume of the uterine cavity. Moreover, membrane rupture can also release phosphatase from lysosomes in amniotic membrane cells and promote the production of prostaglandins. Synthesis, thereby triggering changes in uterine dynamics and initiating uterine contractions. Membrane rupture can soften the cervix, dilate the cervix, and strengthen uterine contractions. In obstetrics, artificial rupture of membranes is the most commonly used intervention method for postterm pregnancy, prolonged labor, and polyhydramnios. There are two main methods. One is that the medical staff first use the left middle and index fin...

Membrane rupture can soften the cervix, dilate the cervix, and strengthen uterine contractions. In obstetrics, artificial rupture of membranes is the most commonly used intervention method for postterm pregnancy, prolonged labor, and polyhydramnios. There are two main methods. One is that the medical staff first use the left middle and index fingers to insert into the vagina for guidance, and hold the toothed forceps in the right hand to tear the fetal membrane, and use the fingers to expand the breach. After the rupture of the membrane, the finger should stay in the vagina After 1-2 uterine contractions, take out the finger after the fetal head enters the basin. When the membrane is ruptured in this way, the amniotic fluid will suddenly spray out or the amniotic fluid will contaminate the clothes of the medical staff; the other is to insert it into the vagina. Drainage tube, which slides inside the tube to connect with the amniotic needle, and uses the drainage tube to drain the amniotic fluid after the membrane is broken. Since the diameter of the drainage tube is fixed, as the opening of the fetal membranes increases, the amniotic fluid will flow out from the outside of the drainage tube. The drainage effect of the membrane rupture method is not good, which is not conducive to the collection of amniotic fluid, and when the membrane is ruptured, the amniotic fluid is suddenly ejected or the amniotic fluid flows out, which will not only pollute the clothing of the membrane rupturer but also affect the hospital environment, which is very inconvenient.
