Diaphragm infusion machine

Abstract

The invention discloses a diaphragm infusion machine which comprises a diaphragm pump and a pulse damper, wherein the pulse damper is arranged at the outlet of the diaphragm pump; the diaphragm pump comprises a pump body, a diaphragm and a piston rod; a pump chamber is formed in the pump body; the diaphragm is arranged in the pump chamber; the piston rod communicated with the pump chamber is arranged in the pump body; a liquid inlet flow channel and a liquid outlet flow channel are formed in the pump body; one-way float valves are arranged in the liquid inlet flow channel and the liquid outlet flow channel; a bubble detector and a flow sensor are arranged at the outlet of the pulse damper; the bubble detector and the flow sensor are respectively with MCU; the MCU is connected with a driving motor of the diaphragm pump and a touch display screen; the diaphragm pump is connected with the driving motor; and the driving motor is a variable frequency motor. The technical aim of the invention is to provide the diaphragm infusion machine which can be automatically controlled. According to the machine, the condition that liquid medicine is contaminated by dropping debris due to friction of a sealing element is avoided, and infusion damping is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a diaphragm 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; And the existing infusion pump is either the price is too high or the infusion pump has a very strong pulse, the strong pulse will make t...

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; And the existing infusion pump is either the price is too high or the infusion pump has a very strong pulse, the strong pulse will make the patient's infusion uncomfortable; and when the patient is infused, especially in winter, the cold medicinal solution makes the patient feel particularly cold , I feel particularly uncomfortable; when the traditional infusion machine is infused, the shaft or the seal may fall off due to the friction between the shaft and the seal and contaminate the liquid medicine
