Problems solved by technology

[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 tis

Embodiment 1

[0032] Invasive arterial puncture catheterization skill simulation trainer, such as Figure 1-2 and Figure 6-7 As shown, including a body 17, the top of the body 17 is provided with a display screen 16 near the left edge, and the top of the body 17 is provided with a simulated blood storage tank 11 near the right edge, and the right side of the body 17 is positioned near the bottom edge from left to The right side is provided with power line 10, brachial artery simulated blood connecting tube 7, simulated blood vessel connecting tube 13 and radial artery simulated blood connecting tube 6, and the right side of the body 17 is provided with a power switch 8 near the top edge; Elasticity outside the radial artery 1 , brachial artery 2 and simulated blood vessels 12 can compress the skin arm model 9 .

[0033] In this embodiment, a brachial artery 2 is provided at the end of the brachial artery simulated blood connecting tube 7, and a second pressure sensor 15 is provided at a p...

Embodiment 2

[0037] In order to make the circulatory system of simulated blood more perfect, the inventor made the following improvements on the basis of Example 1, as Figure 3-5 As shown, the other end of the simulated blood vessel 12 is connected with the other end of the radial artery 1, and the other end of the brachial artery 2 is connected with the position near the other end of the radial artery 1, so that the simulated blood in the brachial artery 2 can enter into the radial artery 1 , so that the simulated blood in the radial artery 1 can enter the simulated blood vessel 12 .

[0038] In this embodiment, an input tube 26 is provided at the bottom of the simulated blood storage tank 11 close to the left edge, a first pressure pump 18 is provided at the bottom of the input tube 26, and an output tube 27 is provided on the right side of the first pressure pump 18. The end of the output pipe 27 is provided with a three-way pipe 19, and the two sides of the three-way pipe 19 are respe...

Embodiment 3

[0043] In order to make the simulated training device for arterial puncture and catheter placement of the present invention more convenient to control and operate, the inventor has added control buttons to the body 17, such as figure 2 , Figure 4-5 as well as Figure 8-10 As shown, the front side of the body 17 is provided with an oblique section, and the oblique section is provided with radial artery blood pressure adjustment key 3, brachial artery blood pressure adjustment key 4 and heart rate adjustment key 5 from left to right. Large and small two buttons, the left side of the body 17 inner wall near the top position is provided with a single chip microcomputer 25, the bottom of the body 17 inner wall near the left side is provided with a second pressure pump 22, and the output end of the second pressure pump 22 is provided with a push button. The right side of the rod 220 and the push rod 220 is provided with a photoelectric sensor 23 , and the photoelectric sensor 23 is...

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.
