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 syrin...

Abstract

The invention discloses an arteriovenous simulation method and device for puncture teaching. Two latex tubes are arranged on the simulation arm to simulate arterial blood vessels and venous blood vessels respectively, and a diaphragm pump is used to extract simulated blood from a liquid storage container, and pump After the simulated blood passes through the first latex tube, it flows through the throttle valve and then enters the second latex tube. Finally, the simulated blood returns to the liquid storage container through the second latex tube to form simulated blood. Circulatory system; by controlling the intermittent start and stop of the brushless DC motor to drive the diaphragm pump, the first latex tube shrinks and expands intermittently, thereby realizing the simulation of human pulse beating; after the simulated blood passes through the throttle valve, it decreases without The process of expansion and contraction is realized, so that the second latex tube realizes the simulation of human veins; when puncture teaching is required, the syringe needle can be inserted into the two latex tubes on the simulated arm to realize arterial puncture and venous puncture respectively simulation training.

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...
