It can accurately control the flow rate and flow rate of the delivered drug solution.

[0003] Critically ill patients have the characteristics of severe illness, rapid progression, and multiple complications. Therefore, doctors often use micro-injection pumps for critically ill patients in clinical practice to accurately and stably deliver antibiotics, chemotherapy drugs, analgesics, sedatives and other liquid medicines, which is beneficial for controlling blood pressure, adjusting blood sugar, continuous analgesia and sedation, etc.

[0004] However, since critically ill patients need to be injected with a variety of different liquid medicines during the rescue process, different liquid medicines can play different therapeutic purposes such as maintaining water and electrolyte balance, alleviating diseases or controlling vital signs during rescue, and since only a small number of infusion catheters can be connected to the joints of the patient's PICC catheter or indwelling needle, the catheter that has been infused with liquid medicine needs to be disconnected in time and switched to other micro-injection pumps, or other syringes with liquid medicines need to be connected to the micro-injection pumps. This is not only cumbersome and inconvenient to operate, but also requires disinfection of the joints every time the infusion catheter is switched, which reduces the work efficiency of medical staff, and the liquid medicines cannot be quickly connected, and the various rescue steps are inconvenient to coordinate, affecting the rescue of critically ill patients.

[0005] Therefore, there is a need for an infusion assembly for critically ill patients that can quickly switch and connect different liquid medicines to improve rescue efficiency. Utility Model Content
