Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the blood transfusion apparatus for flushing stem cell blood bag comprises a puncture body 23, one end of the puncture body 23 penetrating into the liquid storage bag 1 is a puncture end 21, the other end of the puncture body 23 is provided with a liquid outlet 22, the liquid outlet 22 is connected with a liquid conveying pipe 3, the puncture end 21 is provided with a liquid inlet 24, the liquid inlet 24 is communicated with the liquid outlet 22, the puncture body 23 is further provided with a water pipe 25 and a positive pressure port 26, the water pipe 25 is provided with a pipe orifice close to the puncture end 21, the positive pressure port 26 is far away from the puncture end 21, the end of the positive pressure port 26 is connected with a heparin cap 27, the positive pressure port 26 is communicated with the pipe orifice, when the puncture body 23 penetrates into the liquid storage bag 1, the liquid inlet 24 and the pipe orifice are positioned in the liquid storage bag 1, the liquid outlet 22 and the positive pressure port 26 are positioned outside the liquid storage bag 1, when the normal saline is injected into the liquid storage bag 1, medical personnel only need inject normal saline into the reservoir bag 1 through the transfusion needle with the heparin cap 27 of transfusion needle puncture malleation interface 26 department, need not to extract puncture body 23 from the reservoir bag 1, and heparin cap 27 is stronger with the leakproofness of transfusion needle, can prevent that the blood in the reservoir bag 1 from receiving the infection.

Wherein, at the in-process of injecting normal saline into the stock solution bag 1, medical personnel only need puncture heparin cap 27 with the transfusion needle rapidly, need not to extract the back with puncture body 23 from the stock solution bag 1, injects normal saline into the stock solution bag 1 again, the step of simplified operation reduces medical personnel's working strength.

Heparin cap 27 can be dismantled with malleation interface 26 and be connected, and heparin cap 27 is too much after by the number of times that the puncture body 23 punctured, and heparin cap 27's leakproofness can reduce, and before the infusion, medical personnel can take off heparin cap 27 from malleation interface 26, change the heparin cap 27 that the leakproofness is good.

The tip of malleation interface 26 is puncture end 21 dorsad, and when the infusion, liquid storage bag 1 highly hangs on the infusion support usually, and the puncture of liquid storage bag 1 is downwards, and consequently malleation interface 26's tip is downwards, when pouring into normal saline into liquid storage bag 1, and medical personnel can observe the puncture face of heparin cap 27, upwards punctures heparin cap 27 with the transfusion needle, and is comparatively convenient.
