Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to medical teaching technical field especially is related to a human body model for anesthetizing ultrasonic teaching. BACKGROUND
[0002] Ultrasound technology is increasingly widely used in the field of anesthesiology with its advantages of convenience, speed, real-time, no radiation, repeatability, etc. Using ultrasound examination helps anesthesiologists to establish peripheral vascular access and nerve block under visualization, avoid blind puncture, and reduce the incidence of complications. At the same time, important information such as visualized organ anatomical structure, functional state, and systemic hemodynamics can be obtained in real time through ultrasound examination during anesthesia, which can help clinical anesthesiologists to quickly and accurately assess the patient's condition and provide a reference scheme for subsequent treatment. Anesthesiologists need to master the relevant skills of visualized ultrasound anesthesia, including ultrasound-guided vascular puncture and nerve block, bedside ultrasound, and perioperative echocardiography.
[0003] With the comprehensive promotion of the standardization of physician specialist competency building in China, the training of clinical skill training ability is facing serious challenges. The mastery and precision of ultrasound skills not only rely on systematic theoretical teaching, but also depend on the operation skills and experience of the operator. At present, relevant literature suggests that through theoretical teaching, simulation teaching, and clinical practice, the relevant skills of visualized ultrasound anesthesia of anesthesiologists can be improved.
[0004] At present, there are single-skill training models on the market for ultrasound-guided vascular puncture and nerve block. Single-skill training models are mainly single regional modules that simulate the blood vessels and nerves at the corresponding anatomical position. The material can be imaged under the ultrasound equipment and can be used for basic ultrasound-guided vascular puncture and catheterization and nerve block training. However, the existing anesthesia ultrasound-related training models on the market are only regional anatomical modules, such as ultrasound-guided brachial plexus block and central venous puncture model, ultrasound-guided femoral nerve block and femoral artery and vein puncture model, and ultrasound-guided regional nerve block module. They can only meet the basic skill training of ultrasound probe technique, image recognition, and ultrasound-guided puncture operation in anesthesia ultrasound. In addition, most of the existing models use a manual pump to simulate arterial pulsation, and the blood vessels are filled with simulated blood to facilitate the identification of blood vessels and the basic skill operation of vascular puncture under ultrasound. However, there is no simulation of blood flow dynamics, and the central venous pressure cannot be monitored after central venous puncture and catheterization, which is not conducive to the monitoring and observation of the anesthesia process.
