The utility model provides a kind of infusion blood sampling device.In the utility model, after the central venous blood of critical patient is extracted using blood collector, the mixture in syringe is injected into the central vein of critical patient via central venous catheter, so that iatrogenic blood loss can be avoided.After blood sampling, new infusion bottle, new infusion tube and new pump do not need to be used, drug and instrument waste are avoided, and drug and instrument costs are reduced.When the infusion blood sampling device leaves factory, the nipple in the needle cylinder in the syringe is integrally formed with the first catheter and cannot be detached, so that the syringe is not pulled off from the first catheter, and the nipple in the needle cylinder in the syringe is always isolated from the outside and not exposed to the outside, so that external pollutants can be prevented from being injected into the central vein of critical patient, and health and safety threat to critical patient can be avoided.
