Ultrasonic simulation device used for guiding placement of nasointestinal tube

Abstract

The invention discloses an ultrasonic simulation device used for guiding placement of a nasointestinal tube. The ultrasonic simulation device comprises a human pleuroperitoneal cavity model, an esophagus model, a stomach model, a duodenum model, a jejunum model and the nasointestinal tube; wherein the esophagus model, the stomach model, the duodenum model and the jejunum model are fixed into the human pleuroperitoneal cavity model according to the positions of the esophagus, the stomach, the duodenum and the jejunum in the human body; the human pleuroperitoneal cavity model is filled with a material through which ultrasonic waves can penetrate; the insertion end of the nasointestinal tube is made from a material capable of reflecting the ultrasonic waves; the human pleuroperitoneal cavitymodel, the esophagus model, the stomach model, the duodenum model and the jejunum model are each made from a material through which the ultrasonic waves can penetrate, so that the real viscera structure is developed. The ultrasonic simulation device can really simulate the ultrasonic environment in the process of placing the nasointestinal tube, and therefore, medical workers carry on effective skill training of severe ultrasonic-guided placement of the nasointestinal tube.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasound simulation, and in particular relates to an ultrasound simulation device for guiding the placement of a naso-intestinal tube. Background technique [0002] Clinically, for critically ill patients who need ventilator-assisted breathing, or whose intestinal function has not fully recovered, or who have no swallowing function, it is necessary to install a naso-intestinal tube for enteral nutrition supply, that is, insert the naso-intestinal tube into the patient's pylorus through the patient's nasal cavity or mouth, By injecting nutrient solution into the nasoenteric tube to directly provide nutrition to the jejunum of the patient, it can reduce the occurrence of reflux and aspiration in the patient. . [0003] Currently, in order to increase the success rate of placement of naso-intestinal tubes, medical staff generally need to perform the above-mentioned operations with the assistance o...

Problems solved by technology

At present, there is no effective training method for this placement skill clinically, and it is only limited to theoretical explanations, which leads to the inability of medical staff to master this skill well.
