In this embodiment, before use, the sample retention pipette 12 is inserted into the casing 20 of the body fluid detection device, so that the lower end of the pipette body 121 is inserted into the sample retention groove 11; the cuvette lid 13 is then snapped or screwed into the housing 20.
In use, after the sample flows into the sample retention groove 11, the elastic pressing piece 131 is pressed to suck the sample into the pipette body 121.
When the retest is needed, the sample-reserving pipette cap 13 is firstly detached, then the sample-reserving pipette 12 is taken out, and finally the rubber bag 122 is squeezed to extrude the sample for retest.
In this embodiment, the sample retention slot assembly 10 facilitates storage and taking of a sample, and facilitates subsequent retest of the sample.
Example two:
as shown in fig. 4 to 8, the body fluid testing device includes a housing 20, a sampling assembly 30 and a testing assembly 40, and further includes a sample reserving groove assembly 10 in the first embodiment and the modification thereof, the sample reserving groove assembly 10 is installed in the housing 20, and after the sampling assembly 30 and the testing assembly 40 are inserted into the housing 20, the sample reserving groove 11 is communicated with the sampling assembly 30 and the testing assembly 40.
Specifically, the sampling assembly 30 is used to collect a sample, and the sampling assembly 30 is inserted into the housing 20 to discharge the collected sample into the housing 20.
The sample flows into the sample retention groove 11 from the housing 20, and when the sample retention groove 11 is full, the sample flows into the detection assembly 40, and the sample is detected in the detection assembly 40.
By the sample groove assembly 10, a part of the sample is stored while the sample is detected, so that subsequent reinspection is facilitated.
Further, as shown in fig. 6 and 8, a sampling slot 21 and a detection slot 22 are provided in the housing 20, and the sample retention slot 11 is provided between the sampling slot 21 and the detection slot 22.
Specifically, as shown in fig. 5, after the sampling assembly 30 is inserted into the housing 20, the bottom of the sampling assembly 30 is inserted into the sampling slot 21, and the sample collected by the sampling assembly 30 flows into the sampling slot 21.
As shown in fig. 6-7, the test assembly 40 includes a plurality of test strips therein, and the test assembly 40 is inserted into the test slot 22.
Since the sample reserving groove 11 communicates with the sampling groove 21 and the detecting groove 22, the sample flows into the sample reserving groove 11 from the sampling groove 21 and then flows into the detecting groove 22 from the sample reserving groove 11. The test strip in the test assembly 40 performs the primary test on the sample.
Alternatively, the sample in the sampling slot 21 may flow into the detection slot 22 first, and the excess sample in the detection slot 22 may flow into the sample retention slot 11 for storage.
In this embodiment, the sampling slot 21 is a circular groove; the test socket 22 is a flat recess that matches the shape of the flat test element 40.
Alternatively, when the test assembly 40 is cylindrical, the test socket 22 is also a circular recess.
Further, as shown in fig. 6 and 8, a first flow channel 23 and a second flow channel 24 are provided in the housing 20, the first flow channel 23 communicates the sampling slot 21 and the sample reserving slot 11, and the second flow channel 24 communicates the sample reserving slot 11 and the detecting slot 22.
Specifically, the first flow channel 23 is a straight groove, the second flow channel 24 is a bent groove, and the second flow channel 24 is connected to the middle of the detection slot 22, so that the sample can flow towards two sides of the detection slot 22 quickly.
Further, as shown in fig. 5, one end of the first flow path 23 is connected to the bottom of the sampling slot 21, and the other end is connected to the upper portion of the sample reserving slot 11.
Since the sampling slot 21 does not need to store a sample, the bottom of the sampling slot 21 is connected to the first flow path 23, and the entire sample is introduced into the sample retention slot 11.
Since a part of the sample needs to be collected in the sample retention groove 11, the first flow path 23 is connected to the upper portion of the sample retention groove 11, and the sample flows down from the upper portion of the sample retention groove 11 and is collected in the sample retention groove 11.
Further, as shown in fig. 8, one end of the second flow path 24 is connected to the upper portion of the sample retention groove 11, and the other end is connected to the upper portion of the detection slot 22.
Because one end of the second flow channel 24 is connected to the upper part of the sample reserving groove 11, when the sample in the sample reserving groove 11 overflows, the sample flows into the detection slot 22 from the second flow channel 24, and then the sample flows into the detection slot 22 to be collected, so that the sample can be conveniently absorbed by the detection test paper.
In this embodiment, when the sample is detected for the first time, a part of the sample is stored by the sample reserving slot assembly 10, which facilitates subsequent retest. Time is saved, operation is simplified, sample preservation is facilitated, and the sample does not need to be separately maintained again.
