Description

Obstetrical membrane-breaking amniotic fluid drainage combined device

Technical Field

The invention relates to the technical field of obstetrical membrane rupture, in particular to a membrane rupture amniotic fluid drainage combined device for an obstetrical department.

Background

Amniotic fluid is an aqueous liquid that surrounds the lining of the embryo in the amniotic membrane. Amniotic fluid allows the embryo to move freely without causing the uterine wall to be pressed too tightly. Amniotic fluid also provides buoyancy. In addition, since the specific heat capacity of water is high, amniotic fluid can provide a constant temperature environment for the fetus, and the amniotic fluid also lubricates the vagina during production. The amniotic membrane begins to grow and irrigate with water two weeks after fertilization. Some water will flow out of the body when the amnion is ruptured (commonly called water breaking), and most water will remain in the uterus until the fetus is born.

According to the Chinese patent, the amniotic fluid membrane rupture drainage device for obstetrics and gynecology department is disclosed (patent number: CN207286118U), and comprises an amniotic fluid drainage tube, a flow collecting cover, an air bag and a fluid collecting box, wherein the front end of the amniotic fluid drainage tube is connected with the flow collecting cover, the inner wall of the upper end of the flow collecting cover is connected with a membrane rupture spine, the bottom of the amniotic fluid drainage tube is connected with a catheter through a connector, the bottom end of the catheter is connected with the fluid collecting box, and an air outlet tube is arranged at the upper end of the fluid collecting box, so that the problem that medical personnel are inconvenient to use and are not suitable for the amniotic fluid membrane rupture drainage of obstetrics and gynecology department is solved, particularly.
