Problems solved by technology

If the infusion is too fast or too slow, it is difficult to achieve the expected therapeutic effect, and even affect the safety of nursing care.
[0003] The traditional infusion method has poor infusion speed control. During the infusion, the infusion bottle or the infusion bag needs to be lifted high, which is inconvenient for the patient to move during the infusion, and it is also inconvenient to lift the infusion bottle or the infusion bag high in the ambulance with a small space; The infusion method of lifting the infusion bottle or the infusion bag high will not sound an alarm when air enters the infusion line, which is very dangerous for the patient

Abstract

The invention discloses a medical infusion machine which comprises an intelligent control system, an alarming device, a driving device and a piston reciprocating pump. The alarming device, the driving device and the piston reciprocating pump are connected with the intelligent control system respectively, the piston reciprocating pump comprises a pump body and a piston body mounted on the side face of the pump body, a pump cavity is arranged in the pump body and communicated with a piston cavity of the piston body, a piston rod is arranged in the piston body, and a sealing ring is arranged between the piston body and the piston rod. The medical infusion machine is more accurate in infusion flow control, capable of realizing infusion with different flows for different patients and different medicine liquids, more durable and higher in reliability.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a medical transfusion machine. Background technique [0002] Intravenous infusion is a commonly used method of administration in clinical treatment, and the speed of intravenous infusion varies according to the nature of the drug and the constitution of the patient. If the infusion is too fast or too slow, it is difficult to achieve the expected therapeutic effect, and even affect the safety of nursing. [0003] The traditional infusion method has poor infusion speed control. During the infusion, the infusion bottle or the infusion bag needs to be lifted high, which is inconvenient for the patient to move during the infusion, and it is also inconvenient to lift the infusion bottle or the infusion bag high in the ambulance with a small space; The infusion method of lifting the infusion bottle or the infusion bag high will not give an alarm when air enters the infusion line, which...
