Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to critical gynaecology and obstetrics's supersound teaching simulator.
Background
With the gradual release of birth policies in china, medical institutions face challenges such as: 1) the uterine mucosa is damaged due to multiple drug or appliance abortion of a certain part of women who cannot live two fetuses in the childbearing age due to policy factors; 2) the living standard of people is improved, and the excessive nutrition of pregnant women leads to the exceeding of the fetal weight; 3) increasing the number of elderly puerpera; 4) other factors that produce high risk pregnant and lying-in women. All of the above factors increase the risk of perinatal period of pregnant and lying-in women, wherein postpartum hemorrhage is one of the main causes of death of pregnant and lying-in women. In addition, the incidence of pathological pregnancies such as pre-placenta is increasing year by year because of placenta adhesion caused by the damaged uterine mucosa of a patient.
Four major reasons for postpartum hemorrhage are 1. uterine contraction debilitation (70-90%); 2. birth canal injury (20%); 3. placental factor (10%); 4. coagulation dysfunction (l%).
Currently, the main method for clinically diagnosing postpartum hemorrhage is still to make judgment through detailed physical examination of gynecology and obstetrics medical staff, and the method mainly depends on the medical technical level and clinical experience of current doctors, and lacks direct evidences such as objectivity and visibility.
Secondly, the pathological pregnancies such as placenta adhesion caused by the damage of the uterine mucosa of a patient, the preposed placenta and the like have great influence on the perioperative treatment strategy, particularly the selection problem of the anesthesia mode and the anesthesia medicament, and the reason is that most of intravenous anesthesia medicaments and inhalation anesthesia medicaments can affect the fetus through the placenta clinically, so that the newborn generates 'anesthesia effect', such as respiratory depression, muscle tension reduction and the like, and the newborn is reducedApgarAnd (6) scoring.
At present, intraspinal anesthesia is still the best anesthesia mode for pregnant women, but the selection of obstetrical severe anesthesia such as placenta prearrangement, placental premolarity, placenta implantation and the like has contradiction: 1) the peripheral preposed placenta on the front wall of the uterus, wherein if only a fetal membrane tissue or only a partial placenta tissue exists at the lower uterine incision of the uterus and the blood flow signal is less in an ultrasonic CDFI mode, intraspinal anesthesia can be adopted, otherwise, general anesthesia is selected; 2) the placenta implantation of the complete preposed placenta of the posterior wall can also be used for intraspinal anesthesia, and general anesthesia is preferred if the placenta implantation is merged; 3) the area of the fetal disc is small, the bleeding is less, the intravertebral anesthesia can be selected when the fetal heart is normal, and the general anesthesia can be selected otherwise.
The ultrasonic imaging method is commonly used for judging the position, size and shape of an organ, determining the range and physical properties of a focus, providing an anatomical map of glandular tissues and identifying the normality and abnormality of a fetus, and is widely applied to ophthalmology, obstetrics and gynecology, cardiovascular systems, digestive systems and urinary systems.
Bedside ultrasound has the characteristics of real time, dynamic, real and no radioactivity, and is suitable for bedside examination of critical patients. If the gynecologist and the anesthesiologist understand how to carry out the ultrasonic operation, the ultrasonic image can be conveniently and timely collected beside the bed. According to the ultrasonic image representation, experienced anesthesia department doctors can select the optimal anesthesia mode and anesthetic drugs, experienced obstetrics and gynecology doctors can quickly distinguish the reason of postpartum hemorrhage, and direct, visual and objective basis can be provided for clinical treatment decision. However, current anesthesiologists and gynecologists do not operate ultrasonically.
