As shown in fig. 1 and 2, when the push rod 6 slides upwards, the piston 3 can be pushed to slide upwards, so that the volume of the liquid storage cavity 13 is reduced, the pressure is increased, and the volume of the reaction cavity 15 is increased, and the pressure is reduced; when the push rod 6 stretches into a certain distance of the reaction cavity 15, the flow separation film 10 on the piston 3 is pierced by the sampling rod 11, the piston continues to move into the liquid storage cavity 13, the sample liquid in the liquid storage cavity 13 quickly enters the reaction cavity 15 under the action of pressure difference, and the sample liquid stops entering the reaction cavity 15 after the pressure balance, so that the sample liquid is quickly and quantitatively provided for the reagent strip.
As an optional further refinement technical scheme, the upside edge of spacing 12 is connected through a plurality of adhesion points of discontinuity with the bottom of base 4, and the tip of spacing 12 is provided with the bulge that is used for handing for spacing 12 is difficult for droing, and tears through the manpower.
As an optional further detailed technical scheme, the soft rubber cushion 5 is made of elastic plastic and can be sealed and waterproof.
As an optional further detailed technical scheme, the bottle body 2 is made of transparent plastics, so that the liquid level inside the bottle body and the detection result of the reagent strip can be observed conveniently.
The working principle of the utility model is as follows:
first, the bottle cap 1 is unscrewed, the sample to be measured is collected by the collection rod 11, the collection rod is reinserted into the bottle body 2, and the bottle cap 1 is screwed. And then, the bottle body is shaken to ensure that the excrement on the sampling rod and the buffer solution in the bottle are fully mixed.
Then, when the test is needed, the limiting strips 12 are pulled out; bottle 2 is pushed down for upwards promote piston 3 through push rod 6, lead to the volume of stock solution chamber 13 to reduce the pressure increase, reaction chamber 15 volume increase pressure reduces, and flow separation membrane 10 is punctured by sampling stick 11, and the buffer solution that has the sample enters into reaction chamber 15 under the effect of pressure differential fast, and stops after pressure balance to get into reaction chamber 15 and have the buffer solution of sample and get into the test area, makes the reagent strip begin to react and discolour, whether contains the thing of waiting to detect in the demonstration sample.
