Document Type and Number:
WIPO Patent Application WO/2021/213522
Kind Code:
A1
Abstract:
Disclosed are a pharmaceutical preparation with a tracing function, and a delivery system therefor. The pharmaceutical preparation comprises a first drug (11, 11A, 120) and a second drug (12, 12A, 121) in a liquid or gaseous state, wherein the first drug (11, 11A, 120) and the second drug (12, 12A, 121) are each divided into multiple sections, which are arranged in series at intervals in a conduit (200). One of the first drug (11, 11A, 120) and the second drug (12, 12A, 121) is a tracer drug that can be developed in a medical imaging device in the human body. The first drug (11, 11A, 120) and the second drug (12, 12A, 121) are immiscible and satisfy compatibility requirements. The pharmaceutical preparation can comprise an aerobic contrast agent, an aerobic embolic agent and an aerobic perfusion agent. Same can be applied to a variety of contrast techniques by means of a one-step simple operation, saving the dosage of a drug while maintaining a high concentration of the drug. The pharmaceutical preparation is injected into oxygen together with a drug during interventional surgery, which can increase cell activity to improve drug efficacy, thereby achieving an inhibitory effect on tumor cells; and same can also improve the flexibility of drug compatibility, thereby realizing accurate hemodynamic analysis.
