With the closed body fluid indwelling device after the cooperation of test tube component.When in test tube component liquid collected after outwell and take extra liquid in liquid part
Body takes liquid part to check for liquid when extracting from test tube component from taking liquid part lower part drain to pass through when taking after liquid is outwelled in liquid part
It is flowed out in through-hole and exhaust passage.Liquid part and test tube component point are taken taking the lower section of liquid part and test tube component to work as equipped with dish catches
From when the liquid that flows out, measure trickle volume with 0.5ml suction pipe and 5ml measuring cup.
Wherein, the equipment of use is as follows:
Testing result:
Conclusion: when taking liquid part equipped with having annular sidewall below multiple liquid-conveying ducts and through hole of the utility model, from examination
Liquid part lower part no liquid is taken to flow out when extracting in tube assembly, the prior art has 37% when liquid part lower part being taken to extract from test tube component
There is liquid is unrestrained to happen.
Comparative example 3
Test method: the prior art and the utility model respectively use 50 sets of equipment to be acquired liquid, and equipment is to take liquid part
With the closed body fluid indwelling device after the cooperation of test tube component.Liquid is acquired with closed body fluid indwelling device respectively, wherein test tube volume is
8ml, the flow velocity of acquired liquid are that 4ml is per second, are counted after measuring required time with seconds counter when liquid is collected into 8ml in test tube
Calculate average value.
Wherein, the equipment of use is as follows:
Testing result:
Conclusion: adopt it is identical at the minimum of single delivery hole section when liquid under the premise of, the time needed for the utility model less than
The 50% of the prior art, substantially saving the time facilitates patient.
Comparative example 4
Test method: (product technology model: LZQ-01, manufacturer: Wuxi City is triumphant along doctor for the utility model and the prior art
Treat instrument Manufacturing Co., Ltd) the finished surface product, shape, the weight that prepare product is all identical, the identical (mould 4 of mold well number
It is a), the type of cooling, material, the process equipment model that uses are all the same.Under the premise of herein, using the utility model and existing skill
Art produces 20000 respectively and takes liquid part, and measures respectively: required total time, when calculating production needed for individually taking liquid part
Between and product yield rate.
Conclusion: it individually takes liquid part to produce spent time the utility model and spends time taking 54% by the prior art, and close
Lattice rate is higher than the prior art.The utility model high production efficiency and at low cost.
Comparative example 5
Test method: (product technology model: LZQ-01, manufacturer: Wuxi City is triumphant along doctor for the utility model and the prior art
Treat instrument Manufacturing Co., Ltd) the finished surface product, shape, the weight that prepare product is all identical, the identical (mould 4 of mold well number
It is a), the type of cooling, material, the process equipment model that uses are all the same, herein under the premise of, the prior art and the utility model point
Not Sheng Chan 100000 take liquid part, measure respectively: the mold core quantity needed to change evaluates the robustness of mold.Wherein,
100000 take the mold core of the mold of liquid part to replace quantity (corresponding liquid-conveying ducts and exhaust passage).
Conclusion: the corresponding exhaust of the utility model mold, the quantity that the mold core of liquid-conveying ducts is replaced only have prior art mold
Correspondence is vented, the mold core of liquid-conveying ducts replaces the 12.5% of quantity, and die life greatly improved.
