Vacuum state is formed between bottom, the bottom of test paper just contacts with bottom and deviation does not occur, kept between different test paper
Separate state.For the vacuum blood collection diagnosis test tube in storage, transport etc. without using sterile vacuum state is kept under state, it is internal true
Reciprocal of duty cycle scope is 0.1-0.9 atmospheric pressure.
Further, since serum during paper chromatgraphy is tried, it is necessary to start the 5 to 15min of reaction in serum and test paper
Interior reaction is finished, and obtained result is only accurately, and otherwise the reaction time is long or too short all easily causes diagnostic result to lose
Very, mistaken diagnosis is caused.Start the reaction time to accurately grasp test paper and serum, obtain more accurate diagnostic data, can be with
Between accurately being obtained at the beginning of serum and test paper using the principle of reflection of monochromatic source.Further, because serum and test paper react
It overlong time, can cause diagnostic result error is excessive to cause mistaken diagnosis, therefore, a reaction is installed on the upper position of fixed plate
Termination instruction lamp, the color when serum is chromatographed to the position of test paper corresponding to the indicator lamp change, and are incident upon the position
Light is partly absorbed, and the light reflected is changed by color during the reaction termination instruction lamp, is shown and is now viewed
Diagnostic result may be inaccurate result.
A kind of method of quick blood sampling diagnosis, mainly using vacuum blood collection diagnosis test tube recited above, its step is such as
Under：1. needed to gather necessary quantity of blood according to detection project；2. the blood gathered is filtrated to get by filter and treated
Survey liquid；3. read diagnostic result in the 1min after the completion of gathering blood to 15min periods.
Preferably, after the completion of blood is gathered 5min to reading diagnostic result in the 15min periods.
