Description

Technical Field

[0001] The utility model relates to the technical field of medical models, in particular to an umbilical cord placenta model for demonstration. Background Art

[0002] The umbilical cord is the connecting structure between the fetus and the placenta. It is shaped like a rope, with a smooth and transparent surface. It contains connective tissue, an umbilical vein, and two umbilical arteries. The umbilical artery transports waste from the fetus to the placenta, and the umbilical vein transports O2 and nutrients from the placenta to the fetus. Finally, the uterine vein transports metabolic waste from the fetus. Some hormones and antibodies are also transferred from the mother to the fetus through the umbilical cord. After the newborn is born, breathing is established, and the chest pressure decreases, which promotes the blood in the umbilical vein to enter the newborn's body. At the same time, after birth, the newborn's pulmonary blood vessels expand and the systemic circulating blood volume increases. Driven by the pressure of the heart and arterial system, as well as the effect of uterine contraction, the blood in the umbilical cord is pushed into the newborn's circulatory system. After the newborn is born, 23% to 30% of the blood in the umbilical cord enters the newborn within 10 to 15 seconds, and the remaining 70% to 77% mainly enters the newborn within 1 minute after birth. This process is completed within 3 minutes. During the whole process, about 19ml / kg of blood enters the newborn, which is equivalent to 21% of the newborn's blood volume.

[0003] It is recommended that for newborns who do not require positive pressure ventilation, including full-term and premature infants, umbilical cord clamping should be delayed as much as possible, with the best effect being a delay of ≥60 seconds and no more than 3 minutes.

[0004] After the newborn is born, wait for the umbilical cord pulsation to stop (about 1 to 3 minutes after birth), clamp the umbilical cord with two sterile hemostatic forceps at 2 cm and 5 cm away from the base of the umbilical cord respectively, and cut the umbilical cord once at 2 cm away from the base of the umbilical cord with sterile scissors.

[0005] However, the existing umbilical cord placenta model used for demonstration has the following problems during use: since the conventional model is generally an integrated structure, it cannot simulate the pulsation of the umbilical cord well, resulting in poor simulation demonstration effect. Therefore, it is necessary to design a corresponding technical solution to solve the existing technical problems. Utility Model Content
