[0002] With the development of society and technology, the equipment in various fields has been greatly improved. In the clinical treatment of tumors, it is often necessary to cooperate with the interventional department to treat patients, including injecting drugs into the patient's body by means of bolus injection. In existing clinical operations, it is usually the nursing staff who mix the medicaments and then directly inject them. However, for some patients, the dosage of the injected drug is relatively large, and the injection speed needs to be uniform. This will increase the nursing work. In particular, long-term uniform bolus injection will lead to unstable injection force, resulting in uneven injection speed of the medicament.
