Abstract

The invention discloses a medical infusion pump, comprising a pump bottle; a support sleeve rotatably arranged in the pump bottle; a guide rod slidably arranged in the support sleeve; a bag, the expansion bag, the support sleeve and the guide rod form a liquid storage space, and the expansion bag can be switched between a contracted state and an expanded state; a flow guide member arranged in the expansion bag, the flow guide member Corresponding to the liquid outlet, one end of the flow guide is connected to the support sleeve, and the other end is connected to the inner wall of the expansion bag after being twisted. In the present invention, by arranging a flow guide, in the process of expanding the expansion bag, the flow guide is stretched synchronously, and the liquid flowing out of the liquid outlet is divided into two branches by the flow guide, and after being guided by the two sides of the flow guide, A vortex is formed in the expansion bag to promote the mixing of the medicinal liquid. When the medicinal liquid and the physiological saline are injected, the mixing can be carried out, which reduces the workload of medical staff and improves the mixing effect.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a medical infusion pump. Background technique [0002] The infusion pump (analgesia pump) is a postoperative analgesic tool used in the anesthesiology department in recent years. It can maintain a timely and stable concentration of analgesic drugs in the plasma, and allow the patient to press the drug by himself to quickly strengthen the effect. Treatment is more individualized and truly patient-controlled sedation is achieved. [0003] The existing infusion pump mainly includes a pump bottle, an expansion bag, a support sleeve and a guide rod for supporting the expansion bag. When injecting liquid, the liquid medicine mixture is first injected into the expansion bag, and then physiological saline is injected for dilution and expansion. The balloon expands after fluid injection and maintains constant pressure on the fluid. Since there is no gas in the expansion bag, the fluidity ...
