Simulation trainer for invasive arterial puncture catheterization skill

Abstract

The invention relates to the technical field of simulation trainers, in particular to a simulation trainer for invasive arterial puncture catheterization skill. The simulation trainer comprises a machine body, wherein a display screen is arranged at the position, close to the left edge, of the top of the machine body, and a simulation blood storage tank is arranged at the position, close to the right edge, of the top of the machine body; a power line, a brachial artery simulation blood connecting pipe, a simulation blood vessel connecting pipe and a radial artery simulation blood connecting pipe are sequentially arranged at the position, close to the bottom edge, of the right side of the machine body from left to right; and a power switch is arranged at the position, close to the top edge,of the right side of the machine body. The simulation trainer for invasive arterial puncture catheterization skill disclosed by the invention can simulate the real touch feeling and pressure feelingby pressing a skin arm model and built-in radial artery, brachial artery and simulation blood vessel; the corresponding data can be directly displayed through a first pressure sensor, a second pressure sensor, a photoelectric sensor and the display screen, the observation of the user is convenient, and the user can train the invasive arterial puncture catheterization skill.

Description

technical field [0001] The invention relates to the technical field of simulation trainers, in particular to a simulation trainer for skills of invasive arterial puncture and catheterization. Background technique [0002] In the emergency department, intensive care unit, and anesthesiology department, arterial catheterization is used to collect arterial blood in critically ill patients, and dynamic measurement of blood pressure and cardiac output is very common. In the selection of arterial puncture sites, the radial artery is the most common, followed by the brachial artery. Arteries, the radial artery runs relatively straight, the puncture site is flat, and the puncture site is easy to expose. It is often used as the first choice for puncture, while the brachial artery runs toward the inner side of the elbow and is difficult to locate. The subcutaneous tissue is deep and relatively difficult to puncture. , the puncture rate of novice students is very low, but as the proxim...

[0002] In the emergency department, intensive care unit, and anesthesiology department, arterial catheterization is used to collect arterial blood in critically ill patients, and dynamic measurement of blood pressure and cardiac output is very common. In the selection of arterial puncture sites, the radial artery is the most common, followed by the brachial artery. Arteries, the radial artery runs relatively straight, the puncture site is flat, and the puncture site is easy to expose. It is often used as the first choice for puncture, while the brachial artery runs toward the inner side of the elbow and is difficult to locate. The subcutaneous tissue is deep and relatively difficult to puncture. , the puncture rate of novice students is very low, but as the proximal artery, the pulse is more obvious than that of the radial artery in patients with hypotensive shock, and the success rate of puncture also has its advantages; currently there are corresponding skills training and assessment requirements in the standardized training for residents , but there is no corresponding skill trainer, and residents who want to master this skill must implement it directly on critically ill patients. In view of this, we propose a simulation trainer for invasive arterial puncture and catheterization skills
