Detailed description of the invention
As can be seen from Figure 1, a kind of open-heart surgery homoiothermy myocardial protective liquid filling device, it includes transfusion bag 1, infusion pipeline and pressure pipeline etc.Described transfusion bag 1 one upper lateral part is provided with crystal and stops jumping liquid and add entrance 23, and crystal stops jumping liquid and adds entrance add from this.Be provided with homoiothermy introducing port 17 bottom transfusion bag 1, the homoiothermy after filtering in operation adds from this introducing port.Described crystal stops jumping liquid and adds on entrance 23 and homoiothermy introducing port 17 and be also respectively equipped with pressure-resistant seal cap.Crystal stops jumping liquid and homoiothermy mixes in proportion in transfusion bag 1, composition homoiothermy myocardium protecting liquid.Described infusion pipeline and pressure pipeline are connected to bottom transfusion bag 1.
Described infusion pipeline includes dropping funnel 5, flow regulator 6, two pass joint 8 of perforator 2, Y-type three way type 4, band drainage screen, and they are connected successively by conduit 3, conduit 7; Described perforator 2 inserts in transfusion bag 1 bottom interface.During use, connect transfusion needle by two pass joints 8, be used for directly infusing perfusion to aortic root.
Described pressure pipeline includes that medical stainless steel pin 10, piping clip 13, resistance bacterium filter 14, spiral two are logical 15, air bag 16, and they are connected successively by conduit 11.Extruding gasbag 16, is used for pressurizeing in transfusion bag 1.
Described pressure pipeline also connects a pressure monitoring pipeline by Y-type three way type 12, and described pressure monitoring pipeline is provided with female Luer 18, two-way valve 19, pressure obstructing instrument 20, Pressure gauge 22, and they are connected successively by conduit 21.Pressure gauge 22 is used for showing the pressure in transfusion bag 1.
Medical stainless steel pin 10 in described insertion transfusion bag is also provided with a protective casing 9.Protective casing 9 is mounted in advance in transfusion bag 1.Like this, medical stainless steel cushion can be avoided fashionable, wear out transfusion bag.
During this utility model Clinical practice, to be stoped jumping liquid by crystal through puncture needle and add entrance 23 and in transfusion bag 1, add 50ml crystal stop jumping liquid; Divide blood through arterial blood filter three-way interface in art, in transfusion bag 1, add homoiothermy by homoiothermy introducing port 17 through puncture needle.In transfusion bag 1, crystal stops jumping liquid and homoiothermy ratio is 1:4, composition homoiothermy myocardium protecting liquid.Directly will squeeze in transfusion bag containing oxygen homoiothermy through arterial blood filter, and stop jumping after liquid mixes with crystal and pour into.Warm blood cardioplegia closer to normal human body temperature can increase oxygen dissolubility wherein; the aerobic oxidation of myocardial cell during the warm blood cardioplegia being rich in oxygen can increase infant asystole; and then more energy is provided, repays more myocardial cell oxygen debt for myocardial cell acting, thus reach good Myocardial protective effects.
After homoiothermy myocardium protecting liquid mix homogeneously, open flow regulator 6 aerofluxus, connect transfusion needle through two pass joints 8, while ascending aorta resistance is closed, to aortic root infusion homoiothermy myocardium protecting liquid.Time as not smooth in perfusion, can pressurize in transfusion bag 1 through air bag 16, moulding pressure should be less than 50mmhg.As excessive in Pressure gauge display pressure, point out patient to check whether catheter needle gives a discount, in order to avoid affect perfusion effect immediately.Research shows, the perfusion pressure of myocardium protecting liquid has a great impact Coronary endothelial function, and the too high or too low coronary artery endothelial that all may cause damages or affects Myocardial protective effects.Liu Donglu etc. study discovery: the perfusion pressure of cardioplegic solution can protect myocardium safety when < 100 mm Hg.This device provides more suitable injection pressure (50mmHg), and the perfusion pressure of myocardium protecting liquid is too high causes damage coronarius, and then affects the recovery of cardiac function; Perfusion pressure is too low, is difficult to again cardiac muscle is fully poured into, and affects perfusion effect.
This utility model, without the need to through the pressurization of cardiopulmonary bypass unit occlusion pump and alternating temperature, relies on gravity and external pressure to realize aortic root and directly pours into, can ensure in operation process, to use homoiothermy to continue or discontinuous infusion myocardium.
This utility model is simple and reasonable for structure, operation, easy to use, can operating time be shortened; reduce intracardiac blood back; reducing incidence rate and the mortality rate of postoperative complication, and be beneficial to postoperative patient rehabilitation, is a kind of desirable open-heart surgery homoiothermy myocardial protective liquid filling device.Be specially adapted to homoiothermy myocardial preservation in infant operation on heart.
