Problems solved by technology

Both the arterial puncture model and the venous puncture model pulse generating device cannot be integrated with the simulation arm due to their complex structure and bulky size, and they take up a lot of space and are easily damaged during the teaching process.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0016] Example. Arteriovenous simulation method for puncture teaching: connect the power supply (DC24V) to the controller, the controller can set the pulse time, after setting the pulse time, the controller will intermittently provide power to the brushless DC motor according to the setting, brushless DC The motor-driven diaphragm pump sucks in the simulated blood from the liquid storage tank and pumps it out. The simulated blood pumped out by the diaphragm pump is connected to the throttle valve through the first latex tube, and the rear end of the throttle valve is connected back to the liquid storage tank through the second latex tube. The latex tube at the front end of the throttle valve produces intermittent simulated blood similar to the beating of human arteries, and students insert the s...

Abstract

The invention discloses an arteriovenous simulation method and device used for puncture teaching. According to the device, two latex tubes, namely a first latex tube and a second latex tube, are arranged on an emulational arm to respectively simulate an arterial blood vessel and a venous blood vessel, a diaphragm pump is used to extract emulational blood from a liquid storage container, and pumps the emulational blood to the first latex tube; after flowing through the first latex tube, the emulational blood enters the second latex tube through a throttle valve, and finally the emulational blood returns back to the liquid storage container through the second latex tube, so that a simulated blood circulation system is formed; a brushless DC motor is controlled to be started / stopped intermittently to drive the diaphragm pump, so that the first latex tube can shrink and expand intermittently to simulate human pulse beat; after the emulational blood flows through the throttle valve, expansion and shrinkage frequency reduces, even expansion and shrinkage disappear, so that the second latex tube can simulate a human venous blood vessel; when puncture teaching is needed, the two latex tubes on the emulational arm are respectively punctured by an injection syringe needle, so that arterial puncture and venipuncture simulation trainings are realized.

Description

technical field [0001] The invention relates to an arteriovenous simulation method and a device thereof, in particular to an arteriovenous simulation method and a device thereof for puncture teaching. Background technique [0002] In the previous puncture models for teaching, arterial puncture and venipuncture are two independent models. When realizing arterial puncture, the motor acceleration and deceleration mechanism is generally used to reduce the speed to a frequency similar to that of the human pulse, and the simulation is performed through the plunger. Blood is pumped out to simulate the beating of an artery, and a rubber tube is connected to the plunger output to puncture the artery. Generally, a peristaltic pump is used for venipuncture, and the rubber tube is squeezed to output intermittent low-pressure simulated blood, and the rubber tube is connected to the outlet of the peristaltic pump for venipuncture. The main disadvantages of the arterial puncture model are...
