A system for adjusting the infusion rate of oxytocin according to maternal uterine contractions

Abstract

The invention provides a system realizing adjustment on the drip velocity of oxytocin according to maternal uterine contraction. The system comprises a monitoring device, a computer system and an oxytocin drip injection device, wherein the monitoring device and the oxytocin drip injection device are connected with the computer system, the monitoring device is used for monitoring the state of a puerpera, and feeds the state information to the computer system, and the computer system controls the oxytocin drip injection device according to the state information of the puerpera, so that the drip velocity of the oxytocin is adjusted; the oxytocin drip injection device comprises a liquid medicine guide-in part and a liquid medicine guide-out part, and a drip velocity regulator is connected between the guide-in part and the guide-out part; the drip velocity regulator comprises a static plate and a rotation plate which are overlapped together, a through hole is formed in the static plate, and the rotation plate covers the through hole; the angle of rotation of the rotation plate is controlled, so that the through hole forms liquid medicine through holes with different cross sections, and thus the stepless regulation on the drip velocity is realized. With the adoption of the system, the regulation on the drip velocity of oxytocin is monitored in real time according to the conditions including the uterine contraction of the puerpera, and the operation is safe and reliable.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a system which can accurately control the infusion rate of oxytocin according to the uterine contraction of the puerpera. Background technique [0002] Childbirth is a natural process, and no special treatment is required under normal circumstances, but in some pathological conditions, it is necessary to induce and strengthen uterine contractions. There are many existing methods, among which continuous intravenous infusion of oxytocin has a better effect, but there are also many deficiencies. "Chinese Modern Clinical Medicine Impurities"-Medical Journal, Volume 10, Issue 10, October 2012, an article "Oxytocin Intravenous Drip Induction and Oxytocin Infusion" mentioned that "Oxytocin intravenous infusion is a method for inducing labor in certain pathological obstetrics. And an important method to deal with abnormal labor process... The use and dosage of oxytocin generally start from ...

AI Technical Summary

Problems solved by technology

Precautions and contraindications of oxytocin: Oxytocin is mainly used for hypotonic uterine atony. If used properly, it can shorten the labor process and reduce the incidence of delayed labor. However, if used improperly, it can cause uterine rupture, amniotic fluid embolism and fetal uterine failure. Therefore, although the intravenous infusion of oxytocin is safe, it must be observed and monitored by special personnel. If the uterine contraction is too strong or the fetal heart rate changes, the infusion should be stopped immediately.

Summarizing the clinical observations, intravenous infusion of oxytocin is an effective and safe method of inducing labor. As for the dosage and monitoring methods in the application process, it needs to be continuously explored.
