Description
Technical field
the utility model relates to a kind of arteriovenous analogue means, particularly a kind of arteriovenous analogue means for teaching of puncturing.
Background technology
in teaching puncturing pattern in the past, arteriopuncture and venipuncture are respective independently two models, when realizing arteriopuncture, rotating speed is dropped to the frequency of approximating anatomy's beat pulse by general employing motor acceleration and deceleration mechanism, by plunger emulation blood pumped thus simulate arterial pulsation, carrying out arteriopuncture at plunger output terminal connection rubber tube.Generally adopt peristaltic pump during venipuncture, export step low pressure emulation blood by the extruding of peristaltic pump to rubber tube, in peristaltic pump exit, connection rubber tube carries out venipuncture.Arteriopuncture model major defect is complicated in mechanical structure, and easily break down, beat pulse is unadjustable, the constant randomness can not simulated human pulse and beat of pulse.Venipuncture is owing to have employed peristaltic pump, and cost is high and volume is larger.Arteriopuncture model and venipuncture model pulse generating means all cannot combine together with emulation arm because complex structure is bulky, take up room more greatly and easily damage in teaching process.
Utility model content
the purpose of this utility model is, provides a kind of arteriovenous analogue means for teaching of puncturing.It can realize the simulation of artery and vein simultaneously, and structure is simplified, advantage of lower cost.
the technical solution of the utility model: a kind of arteriovenous analogue means for teaching of puncturing, it is characterized in that: comprise emulation arm, emulation arm is provided with the first emulsion tube and the second emulsion tube, first emulsion tube one end by membrane pump with store the fluid reservoir emulating blood and be connected, the other end is connected by throttling valve one end with the second emulsion tube; The other end of described second emulsion tube is connected to described fluid reservoir.
aforesaid for puncturing in the arteriovenous analogue means of teaching, described membrane pump is connected with brshless DC motor, and brshless DC motor is connected with power supply by controller.
aforesaid for puncturing in the arteriovenous analogue means of teaching, described first emulsion tube and the second emulsion tube are positioned at inside emulation arm wrist, and throttling valve is positioned at the middle finger root place near emulation arm.
aforesaid for puncturing in the arteriovenous analogue means of teaching, be coated with simulation skin outside described emulation arm, described first emulsion tube and the second emulsion tube are positioned at simulation skin.
aforesaid for puncturing in the arteriovenous analogue means of teaching, described membrane pump, fluid reservoir and brshless DC motor are all integrated in emulation arm.Brshless DC motor and membrane pump volume all less, emulation arm inside can be integrated into well,
compared with prior art, the utility model can produce the intermittence emulation blood flow of approximating anatomy's arterial pulsation, student can by thrusting the first emulsion tube to simulate arteriopuncture by syringe needle tube, and emulate blood by throttling downstream pressure and just reduce, it is similar that the emulation blood pulseless jumping phenomena reduced and vein emulate blood, can simulate vein blood vessel well, syringe needle tube is thrust the second emulsion tube simulation venipuncture by student.Owing to have employed brshless DC motor and the membrane pump of small volume, whole pulse generating means and fluid reservoir can be integrated on an emulation arm, external DC24V power supply is powered to controller, and controller can regulate arbitrarily pulse rate to use throttle valve adjustment arterial pressure to make this equipment more close to the blood circulation of human body real simulation simultaneously.The integrated volume of whole device height is little, and structure simple fault rate is low, and frequency modulation is convenient closer to human pulse, and high resiliency emulsion tube puncture-resistant can increase serviceable life, and artery and vein puncture can realize on an emulation arm.
whole device height of the present utility model is integrated, volume is little, structure simple fault rate is low, the arteriovenous of simulation is closer to the truth with human body, and pulse, the blood pressure of simulation all can regulate easily, the emulsion tube puncture-resistant of use can increase serviceable life, and the teaching exercise of artery and vein puncture can realize on an emulation arm, very convenient, also reduce cost.
