Use: (1) Before use, please read the safety instructions and the instructions attached to the tin foil package medicine, check the expiration date printed on the connecting end of the tin foil package and pay attention to the good quality of the product. If the product is defective, please say the product number. (2) Insert the medicine wrapped in the tin foil into the syringe, put it all the way to the end and connect the mixing nozzle. When using the medicine wrapped in the tin foil, the starting temperature is at least 5 degrees Celsius or more. (3) Before the perfusion tube is put into the syringe, when the release rod is pressed down, the push rod is pulled to the end, the small tube of the perfusion cylinder is clenched, and the large tube of the perfusion cylinder is inserted into the syringe first, and then the small tube is screwed into the syringe to position. (4) With the pull, the tin foil medicine can be automatically pierced by the tip on the connecting end of the medicine bag. When the two agents pass through the mixing nozzle, it can be seen that the medicine is mixed. When the medicine bag is opened (the medicine that has just flowed out), the medicine knocked out by the first two strokes needs to be discarded and is not suitable for use. When the mixing nozzle is changed, the medicine that first comes out may be discarded, and the pull must be pulled to the end as much as possible.
