Description

Animal Model of Extracorporeal Circulation in Rats tests supporting pipeline

Technical field: this utility model design belongs to the consumptive material of medical animal experiment, in order to optimize and combine the operating procedure that rats in vitro circulation experiment model is set up.

Background technology: Animal Model of Extracorporeal Circulation in Rats is the important animal model of Cardio-pulmonary Operation correlational study, it is all piece together transformation by interim pipeline to form that the center using this model to carry out experimentation both at home and abroad is at present close to, not only increase the amount of labour of operator, expend time in, make the risk that experiment is complicated, increase de-pipe air inlet, and can not ensure that the standardization of aseptic condition and the experiment baseline of testing is fixed.For above situation, the supporting pipeline used in this model is optimized integration by us, both the preliminary filling of extracorporeal circulation can be quantized to unify baseline, in turn ensure that the foundation of experiment aseptic condition and improves conventional efficient.

Summary of the invention: goal of the invention of the present utility model optimizes the operating procedure of rats in vitro circulation experiment model foundation, ensures the foundation of medical animal experiment aseptic condition, and extracorporeal circulation priming volume baseline criteria in experiment fixed.This utility model is a kind of supporting pipeline set up for rats in vitro circulation experiment model, it is characterized in that: comprise J-shape guiding steel wire, venous drainage pipe, return passage, return passage and thermode connecting pipe, thermode and membrane lung connecting pipe, membrane lung and arterial cannulation connection tube, preliminary filling exhaust connection, standby pipes, described venous drainage tip end has symmetrical side opening and labelling number, venous drainage pipe tail end is Rule projection, venous drainage pipe is contained in described J-shape guiding steel wire, described venous drainage pipe is connected with return passage, described return passage lateral wall is marked with containing mark, top, sidewall, bottom is fixed with Rule projection respectively, described return passage is connected return passage blood outlet with thermode connecting pipe and thermode enters blood mouth end, described thermode is connected thermode blood outlet with membrane lung connecting pipe and membrane lung enters blood mouth end, described membrane lung and arterial cannulation connection tube junctional membrane pneumorrhagia mouth and arteria caudalis intubate, membrane lung is connected with arterial cannulation connection tube and return passage when preliminary filling by described preliminary filling exhaust connection, carry out front system exhaust preliminary filling of making a connection.This Animal Model of Extracorporeal Circulation in Rats tests supporting pipeline, comprise venous drainage pipe 37cm, internal diameter 1.5mm (includes diameter 0.89mmJ-shape guiding steel wire 47cm, the symmetrical side opening 10 of diameter 1.5mm is provided with in the most advanced and sophisticated 1.4cm of drainage tube, apart from most advanced and sophisticated 3cm, 4cm, 5cm place indicates mark line), (volume is designed to 20ml to return passage, lateral wall is marked with containing mark, shape is that eccentric funnel formula is containing lid container, there are 3 Rule on top for being connected with jugular vein drainage tube and the process such as administration fluid infusion), return passage and thermode connecting pipe 15cm, thermode and membrane lung connecting pipe 34c, membrane lung and arterial cannulation connecting pipe 32.5cm and preliminary filling exhaust connection 20cm and standby pipes 5cm, each connection tube, standby pipes internal diameter is 2.5mm.Each junction adopts male and female Rule screw-fashion to connect, simple and firmly.Return passage material is Merlon, and pipe material is polrvinyl chloride.Concrete connected mode is as Fig. 1.

Accompanying drawing illustrates: be further described this new design with example by reference to the accompanying drawings.

Detailed description of the invention: this supporting circuit design becomes sterile sleeve bag, experimentally demand is unpacked and to be connected through Rule spiral according to connection diagram (as Fig. 1).Concrete connection is as follows: penetrate with the guiding of built-in J-shape guiding steel wire (9.) when Central catheterization is carried out at venous drainage pipe (1.) tip, penetrate seal wire in process to exit gradually, in time arriving right atrium, seal wire all exits, drainage tube afterbody Rule end connects return passage (2.) Rule, top, Rule, return passage bottom is connected with thermode (4.) by 15cm pipeline (3.), then Rule, thermode upper end is connected with toy oxygenator (7.) afterwards by 32.5cm pipeline (5.) press pump (6.), last oxygenator Rule is connected with arterial cannulation by 34cm pipeline (8.).(adopt an extra 20cm pipeline (10.) and 34cm pipeline to be connected to Rule, return passage top during preliminary filling aerofluxus, preliminary filling liquid circulated carry out the preliminary filling aerofluxus of system).
