Detection device of medical infusion pump

Abstract

The invention discloses a detection device of a medical infusion pump. The detection device is structurally composed of four parts including a bubble generation unit, a liquid flow detection unit, a liquid pressure detection unit and a control unit. The bubble generation unit and the liquid flow detection unit are connected through a soft pipe. The liquid flow detection unit and the liquid pressure detection unit are connected through a three-way joint and an electromagnetic valve. The control unit is used for controlling work of a whole system and is electrically connected with the bubble generation unit, the liquid flow detection unit and the liquid pressure detection unit. By means of the detection device of the medical infusion pump, flow and pressure detection is completed, detectioncapability indexes such as the flow, the accumulative amount and the blocking pressure of the infusion pump can be calculated and evaluated according to JJF 1259-2010 medical injection pump and infusion pump calibration specification requirements, data transmission can be conducted in time, real-time online detection is achieved, and the natural quality management requirement is met.

Description

technical field [0001] The invention relates to the field of quality inspection, more specifically, a medical infusion pump inspection device. Background technique [0002] Medical infusion pumps (hereinafter referred to as infusion pumps) are usually mechanical or electronic control devices, which control the infusion speed by acting on the infusion catheter. It is often used in situations that require strict control of infusion volume and drug dosage, such as the application of vasopressor drugs, antiarrhythmic drugs, intravenous infusion or intravenous anesthesia for infants and young children. [0003] Intravenous infusion is a common way of administration in clinical treatment. According to the nature of the drug and the constitution of the patient, the speed of intravenous infusion is also different. 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. [0004] The infusion pump i...

Problems solved by technology

[0006] The working pressure of the infusion pump should not exceed the specified maximum pressure, otherwise the high-pressure sealing ring will be deformed and leakage will occur; the infusion pump has no mobile phase outflow and no pressure indication, the reason may be that there is a large amount of gas in the infusion pump, or it may be The sealing ring is worn and needs to be replaced; the pressure flow of the infusion pump is unstable, which may be caused by air bubbles that need to be removed, or foreign matter in the one-way valve; the cause of excessive pressure is that the pipeline is blocked and needs to be removed or cleaned; The reason for the decrease may be that there is a leak in the pipeline
