Close liquid, so its for blue, the color can intuitively from transparent Connect of Vein pipe by observation of students to.When simulation vein
When blood is entered in oxygenator, the alkaline solution accommodated in oxygenator is reacted, and red is presented, which can be intuitively from saturating
It is arrived in bright artery connecting tube by observation of students.The variation of color discloses venous blood and exchanges with oxygen in lung's progress oxygen conjunction
To the change procedure of arterial blood and the result of variation.In this way, student still can be straight in the case where not using true blood
It connects and observes how the oxygen exchange process of arteriovenous blood occurs, and then deepen the understanding for flowing through journey to blood.Work as simulation
It after arterial blood flows back to simulation human body, and is reacted with litmus reagent, adds acid solution at this time just and will form simulation venous blood, from
And the variation from red to blue is showed, and it on the one hand can reveal that arterial blood becomes the process of venous blood in human body, it is another
Aspect can be such that teaching simulation process circulation carries out, save the cost.
Further, vein blood vessel, the first blood pump, flow monitoring meter and constant temperature blood reservior are simulated and passes through Connect of Vein pipe
It is sequentially connected, oxygenator, the second blood pump, baropacer and simulation artery are sequentially connected by artery connecting tube, and vein connects
Adapter tube is blue, and artery connecting tube is red.Connect of Vein pipe is different from the color of artery connecting tube, discloses venous blood and oxygen
Gas carries out oxygen conjunction exchange in lung and obtains the change procedure and result of variations of arterial blood.In this way, without using true blood
In the case of, how the oxygen exchange process that student still can observe directly arteriovenous blood occurs, and then deepens to blood
The understanding of circulation process.
Above embodiment is preferred case of the invention, the protection scope being not intended to limit the invention.
