Embodiment Construction
[0016] Below in conjunction with accompanying drawing, further illustrate structure and working principle of the present invention:
[0017] see figure 1 , the present invention proposes a device for measuring and detecting the bubble alarm accuracy of a blood transfusion infusion pump, which includes a micro gas injector 6 and a detection pipeline 5 .
[0018] The micro gas injector 6 is a gas injection device with digital display (or scale marking) of gas volume. It is a precision instrument used in general biological experiments or medical assays. It is reversely applied here to make it a precision gas injection pump. Its metering is adjustable and its metering accuracy is high, reaching the level of ? Bubble detection requirements. When used as the micro-injector, its suction pipe is not used, and a suitable gas injection needle is installed at the inlet of the suction pipe to prepare for injecting air into the liquid path. The precision micropipette can be selected in ...

The invention discloses a device for measuring and detecting bubble alarming precision of a blood transfusion and infusion pump. The device comprises a detection pipeline and a microscale air injection apparatus, wherein the detection pipeline comprises a three-way pipe connector, a liquid inlet connecting pipe and a liquid outlet connecting pipe; the liquid inlet connecting pipe and the liquid outlet connecting pipe are respectively connected with two of the pipe heads of the three-way pipe connector, an inner cone connector connected with an infusion apparatus is arranged at the other end of the liquid inlet connecting pipe, and an outer cone connector with a nut is arranged at the other end of the liquid outlet connecting pipe; the third pipe head of the three-way pipe connector is used as an air injection connecting pipe, a rubber plug is arranged at the opening of the pipe, the microscale air injection apparatus is an air injection device with the function of number display of the air volume or scale marking function, the air injection needle of the air injection device penetrates through the rubber plug of the air injection connecting pipe of the detection pipeline, and air can be injected into the detection pipeline. The device is adapted to various infusion pumps used by the current medical institutions, can measure and detect the bubble alarming precision of the infusion pump on the premise that any part of the infusion pump is not changed, and has the characteristics of simple structure, high measuring precision, good practicability and the like.
Description
technical field [0001] The invention relates to the detection, measurement and evaluation technology of the air bubble detection accuracy of a blood transfusion infusion pump. Background technique [0002] Intravenous blood transfusion is the most commonly used clinical treatment. At present, a large number of infusion pumps are used for clinical treatment. At present, there are the following standards for the production and use of blood transfusion infusion pumps: International Standard IEC60601-2-24: 1998, IDT; National Standard GB9706.27-2005 Part 2-24: Special Requirements for Safety of Infusion Pumps and Infusion Controllers. [0003] There is an important technical requirement in the safety technical requirements of blood transfusion infusion pumps, which is the bubble alarm function. However, in the quality control testing of blood transfusion infusion pumps, there is still no clear detection method and standard for the detection of bubble control accuracy. Content...
