Description

Technical Field

[0001] The utility model relates to the technical field of pericardiocentesis, in particular to a training model for ultrasound-positioned pericardiocentesis. Background Art

[0002] Pericardiocentesis is a diagnostic and therapeutic technique that uses a puncture needle to directly puncture the pericardial cavity. Pericardiocentesis must be performed under sterile techniques, with local application of procaine anesthesia. The puncture site should not be too deep to avoid puncturing the atrium, ventricle, or coronary artery, causing a large amount of blood accumulation in the pericardial cavity. Patients who undergo pericardiocentesis can understand the nature of the pericardial effusion by testing the fluid in the pericardial cavity, and identify the cause of pericarditis based on the nature of the pericardial effusion. Although pericardiocentesis has certain risks, it is still a relatively safe diagnostic and therapeutic method if it is performed carefully and strictly according to the operating procedures.

[0003] Due to the high risk of pericardial puncture, medical staff need to conduct a large number of experiments in advance before they can perform actual operations, so they need to use training models for simulation training. When practicing pericardial puncture or thoracentesis, the model needs to be changed from a supine position to a semi-recumbent position or a sitting position. Currently, the position adjustment of the puncture practice model requires manual positioning, which takes a long time to adjust the position before practice, thereby reducing the efficiency of puncture practice.

[0008] Furthermore, a screw is screwed together on one side of the bottom support plate, and the bottom end of the screw is fixedly connected to the output end of the servo motor, and the servo motor is fixedly connected to the inside of the experimental box. Two socket blocks are fixedly connected to the side wall of the bottom support plate, and a limit rod is slidably socketed in both of the two socket blocks, and the limit rod is fixedly connected to the experimental box.

[0009] Furthermore, the internal cavity of the upper body model is made of high-elasticity silicone rubber, and the pericardial cavity, thoracic cavity and abdominal cavity inside the upper body model contain corresponding serous cavity fluid.

[0010] Furthermore, both ends of the top of the experimental box are fixedly connected with slide rails, a protective cover is slidably connected between the two slide rails, and a loudspeaker is fixedly arranged on the side wall of the experimental box.

[0011] Furthermore, a liquid receiving pool is fixedly arranged inside the experimental box, two inclined plates are symmetrically fixedly connected inside the liquid receiving pool, a liquid collecting port is arranged at the center position of the bottom of the liquid receiving pool, a drainage pipe corresponding to the liquid collecting port is fixedly connected to the bottom of the liquid receiving pool, and the drainage pipe is fixedly connected to the side wall of the experimental box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When it is necessary to practice pericardiocentesis, the protective cover can be removed from the top of the experimental box first, and the output end of the servo motor can drive the screw to rotate, so that the screw can drive the bottom support plate and the lifting frame to rise to the panel position, and then the stepper motor can drive the universal joint and the rotating rod to rotate, so that the lifting frame and the upper body model can be driven to rotate a certain angle through the connecting seat, so that the upper body model is adjusted from a supine position to a semi-recumbent position, so that personnel can practice pericardiocentesis conveniently. Since the stepper motor has a motor shaft self-locking function, the upper body model can be kept from shaking during the puncture practice, thereby ensuring the stability of the puncture practice. When thoracentesis practice is required, the upper body model can be quickly adjusted to a sitting state, so that it can simulate the human body to perform large-scale automatic position adjustment, which can improve the efficiency of puncture practice without manual model position adjustment.

[0014] 2. The upper body model cavity is made of highly elastic silicone rubber, and its frame is made of composite resin. The pericardial cavity, thoracic cavity and abdominal cavity contain corresponding serous cavity fluid. Therefore, the model can simulate standardized patients and improve the real experience of puncture practice. A liquid receiving pool is set inside the experimental box, so the serous cavity fluid flowing during puncture can be received and collected. BRIEF DESCRIPTION OF THE DRAWINGS
