Teaching model of internal jugular vein puncture

Abstract

The invention relates to a teaching model of internal jugular vein puncture. The model includes a puncture module, a substrate, and simulated epidermis. The puncture module includes simulated muscle and simulated blood vessels arranged in the simulated muscle according to the anatomic positions; an accommodating cavity for accommodating the puncture module is formed in the substrate, and the simulated epidermis is arranged on the surface of a body, covers the surface of the puncture module and simulates the neck skin of the human body. The cost is very low, the raw materials are simple and easy to obtain, and thus the model can be well popularized; the manufacturing method is simple and can be completed manually without consuming a large amount of labor. Since the puncture module and the simulated epidermis are arranged, many functions are achieved, and people can practice a series of related operation such as body surface positioning, negative pressure needling, fluid pumpback, judgment of arteries and veins, pressure measurement, hand fixation, guiding-wire placement, pulling of a puncture needle, guiding-wire pressing, catheter placement, pull-out of a guiding wire, and catheterfixation.

Description

technical field [0001] The invention relates to the field of medical teaching models, in particular to a teaching model of internal jugular vein puncture. Background technique [0002] Emergency rescue is an inevitable situation for every doctor. Numerous emergency rescue technologies, such as central venous puncture, mechanical ventilation, hemodynamic monitoring, blood purification, tracheal intubation, etc., are the key to successful rescue of patients. In these techniques, fast and accurate central venous catheterization is often the basis of rescue, and it is also a content that is often encountered in clinical practice and difficult to learn by oneself. [0003] Effective training for central venous catheterization is extremely important, which will not only enable young doctors to fully and solidly master the above techniques, but also improve the safety of emergency medical care and hospital-wide rescue. However, the current society pays more attention to medical sa...

Problems solved by technology

The above-mentioned patents only have venous blood vessels, the items that can be practiced are limited, and the functions are not many

And in order to give practitioners more intuitive learning, it is necessary to place the module on the torso model with corresponding grooves for puncture. The cost of the torso model is still high, and it still cannot achieve the purpose of one per person in the training process, and The disadvantage of large volume has not been changed, it is difficult to meet the purpose of multiple people practicing at the same time, and it is impossible to efficiently complete the scheduled teaching goals within a limited teaching time
