Abstract
The invention provides a flow type counting chamber and a urine sample sampling method thereof. The center of the flow type counting chamber is provided with a testing inner cavity (7), and the side of the flow type counting chamber is provided with a bypass inner cavity (8); the inner space height of the bypass inner cavity (8) is more than that of the testing inner cavity (7); a sample suction pipe (6) is additionally arranged on the basis of a general flow type counting chamber; and three inlet pipes form a tee joint at the bypass inner cavity (8). a urine sample inside the flow type counting chamber firstly flows through the bypass inner cavity (8) before collected image detection, a part of the urine sample are sucked into the testing inner cavity (7) during image collection, and the urine sample inside the bypass inner cavity (8) continuously moves forwards at the time to take away larger substances which are to thrust into the testing inner cavity (7), therefore the blocking phenomenon of the flow type counting chamber can be reduced.
Description
Technical field
The invention belongs to urine micro measurement technical field, be specifically related to a kind of streaming counting pool structure and counting chamber urine sample input mode in streaming arena testing process.
Background technology
In the urine sediments analyzer of existing employing streaming microscopy mode, counting chamber urine sample input mode is as follows in the streaming counting pool structure of use and the testing process:
Existing streaming counting pool structure is referring to Fig. 2: it is by glass film plates 1, median septum 2,3 three bonding forming of plate of cover plate on glass; There is an opening in median septum 2 central authorities, are clipped between glass film plates 1 and the cover plate on glass 3 to form a cavity, for test inner chamber 7, at glass film plates about 1 two horizontal through hole are arranged, and interior insertion sample introduction pipe 4 and go out sample pipe 5 is communicated with test inner chamber 7 respectively.
Counting chamber urine sample input mode in the testing process:
Sampling pump work makes urine sample successively by counting chamber front end suction tube road, enters test inner chamber 7 through sample introduction pipe 4, flows through sample pipe 5 again and enters suction tube road, counting chamber rear end.
After definite urine sample flow through test inner chamber 7, sampling pump quit work, and adopts figure and tests pump work, made urine sample continue steadily to finish by test inner chamber 7 to adopt the figure test.
Under this kind mode, big small impurities in the urine sample all wants to push through test inner chamber 7, but highly all very little (the common 0.02-0.13 millimeter of test inner chamber 7, the Tai Gaocaitu effect is bad), therefore easily stifled test inner chamber 7 for reducing the latch up phenomenon in streaming counting pond, needs a kind of new method, the big material that it can reduce in the urine sample is got into the phenomenon of testing inner chamber, and the composition major part that will detect in the arena can enter the test inner chamber.
Summary of the invention
For reducing the latch up phenomenon in streaming counting pond, the present invention proposes counting chamber urine sample input mode in a kind of streaming counting pond and the testing process.
Technical scheme of the present invention is as follows:
A kind of streaming counting pond, it is by glass film plates, median septum, three bonding forming of plate of cover plate on glass; There is an opening in median septum central authorities, be clipped in and form a cavity between glass film plates and the cover plate on glass, be the test inner chamber, two horizontal through hole are arranged about glass film plates, be inserted with the sample introduction pipe in it and go out the sample pipe, sample introduction pipe outer end connects the suction tube road of streaming counting pond front end, and the outer end that goes out the sample pipe connects the suction tube road of rear end, streaming counting pond.
Testing the inner chamber next door and between glass film plates and median septum, also be provided with a bypass inner chamber in the streaming counting pond, two chambeies communicate, the outage degree is greater than outage degree in the test inner chamber in the bypass inner chamber, the sample introduction pipe that inserts by two horizontal through hole about glass film plates and go out the sample pipe and be communicated with the bypass inner chamber respectively, another side at glass film plates has another horizontal through hole, in be inserted with suction tube, be communicated with the test inner chamber, the outer end of suction tube is used for connecting adopts figure and tests pump.
Utilize above-mentioned streaming counting pond to carry out the mode of urine sample sample introduction in a kind of streaming arena testing process, its step is as follows:
Sampling pump work makes urine sample successively by front end suction tube road, streaming counting pond, enters the bypass inner chamber through the sample introduction pipe, flows through the suction tube road that the sample pipe enters rear end, streaming counting pond again;
After definite urine sample flows through the bypass inner chamber, sampling pump is worked at a slow speed, urine sample is moved on, adopt figure simultaneously and test pump work, with the urine sample part inspiration test inner chamber that flows through in the bypass inner chamber, urine sample is steadily finished by the test inner chamber and is adopted the figure test by suction tube.
The present invention is to have increased with adopting figure with the maximum difference in common streaming counting pond, front and tests the suction tube that pump is connected, and three inlet pipes have formed a threeway at bypass inner chamber place.Not to enter the test inner chamber when urine sample enters counting chamber at first, test inner chamber but when adopting figure and need, just urine sample is sucked from the bypass inner chamber, and the urine sample that the big material of wanting to get into the test inner chamber is flow through the bypass inner chamber by the back is taken away, therefore can reduce the latch up phenomenon of testing inner chamber, and the composition major part that will detect in the arena can enter also and tests inner chamber and flow through counting chamber.
Description of drawings

The stereographic map of the existing streaming counting pool structure of Fig. 2.
Embodiment
This streaming counting pool structure is referring to Fig. 1, and it is bonding and form by glass film plates 1, median septum 2, cover plate on glass 3, and there is a rectangular aperture in median septum 2 central authorities, are clipped in and form a cavity between glass film plates 1 and the cover plate on glass 3, are test inner chamber 7; Test inner chamber 7 next doors and between glass film plates 1 and median septum 2, also be provided with a bypass inner chamber 8, two chambeies communicate, the outage degree is greater than outage degree in the test inner chamber 7 in the bypass inner chamber 8, in about 1 two horizontal through hole of glass film plates, insert sample introduction pipe 4 and go out sample pipe 5, be communicated with bypass inner chamber 8, in the horizontal through hole of another side, insert suction tube 6 and be communicated with test inner chamber 7.
Counting chamber urine sample input mode in the testing process:
Sampling pump work makes urine sample enter bypass inner chamber 8 by counting chamber front end suction tube road, sample introduction pipe 4 successively, flows through sample pipe 5 again and enters suction tube road, counting chamber rear end;
After definite urine sample flows through bypass inner chamber 8, sampling pump is worked at a slow speed, and urine sample is moved on, and adopts figure simultaneously and tests pump work, with the urine sample part inspiration test inner chamber 7 that flows through in the bypass inner chamber 8, urine sample is steadily finished by test inner chamber 7 and is adopted the figure test by suction tube 6.
