Technical Field

The utility model relates to a radiation nursing teaching and training technical field at the job especially relate to a contrast agent injection teaching of image branch of academic or vocational study and training simulation operation equipment.

Background

The contrast agent is an indispensable medicine in medical image diagnosis, and the injection of the iodine-containing contrast agent in CT enhancement examination is realized by connecting a high-pressure injection device with a peripheral venous indwelling needle of a patient. The working principle of the injection belongs to high-pressure injection, the conventional injection speed is higher, the general speed is more than or equal to 2.5ml/s, and serious adverse reactions such as air embolism, extravasation, tube explosion and the like can occur if the operation is not proper, so the requirements on the puncture of an indwelling needle and the injection operation of a contrast agent are higher.

Contrast injection is one of the main projects of radiation care work, and meanwhile, teaching and training of contrast injection is also the key point and difficulty of radiation care teaching and training different from other subjects. The teaching and training of the contrast agent injection comprises two parts of high-pressure resistant remaining needle puncture and contrast agent injection. However, in the traditional contrast agent injection, both in the clinical teaching of the nursing staff and in the clinical standardized training of the staff, due to the lack of related teaching and training simulation equipment, the training and the examination can only be directly performed on the clinical patients, so that the related training and the examination operation of the nursing staff and the staff training staff are influenced and restricted, the improvement of the clinical skill is directly influenced, and even the prevention and the control of the potential safety hazard of the examination patients and the quality and the diagnosis effect of the examination images can be influenced.

Especially for the nursing life who has never been contacted with the clinic before, the training and examination on the clinic patient can generate tension, anxiety, fear and great psychological pressure, because in the actual operation process, compared with the clinic venous transfusion indwelling needle, the model of the high pressure resistant vein indwelling needle required by contrast agent injection is thicker, the requirements on the puncture accuracy and success rate of an operator are very high, if the puncture is unsuccessful or repeated puncture can cause the damage of blood vessels, the extravasation of the contrast agent can be generated; and repeated punctures can increase patient's misery. If the model of the high-pressure resistant indwelling needle or the injection speed of the contrast agent is selected or is not operated properly, the image quality is poor, the inspection effect is influenced, and the situations of tube bursting, tube breaking and the like of the indwelling needle are easy to occur; if the high-pressure resistant remaining needle is improperly fixed, the conditions of tube detachment, exosmosis of contrast agent and the like can occur; because the flow rate of the high-pressure bolus injection is very high, if the high-pressure injection is not operated properly or is not skilled, air enters the body of a patient along with a high-pressure pipeline, adverse reactions such as air embolism and the like occur, and even the life of the patient is threatened. These operations all need to be repeatedly operated and trained on simulation equipment, and the operation can be skillfully mastered after consolidation.
