[0034] The following combination Figure 1-3 The utility model is described in further detail.
[0035] Example 1
[0036] Reference Figure 1-3 As shown, this embodiment provides a stool sample filterable reagent bottle, including a reagent bottle assembly, the reagent bottle assembly includes:
[0037] A sampling bottle 1, wherein the sampling bottle 1 comprises a sampling bottle cap 11 arranged at the bottle mouth of the sampling bottle 1;
[0038] The filter bottle 2 includes a filter bottle cap 21 disposed at the bottle mouth of the filter bottle 2, two opposite ends of the filter bottle 2 along the height direction are respectively flush with two opposite ends of the sampling bottle 1 along the height direction, and a horizontal end surface 22 is disposed on a side of the filter bottle 2 away from the sampling bottle 1;
[0039] The sampling bottle 1 and the filtering bottle 2 are connected through the liquid passage 3 , the axis of the liquid passage 3 is horizontally arranged, a filtering membrane 31 is arranged in the liquid passage 3 , and the lying end surface 22 is a plane perpendicular to the axis of the liquid passage 3 .
[0040] The working principle of the utility model is as follows: after placing a stool sample and a diluent in a sampling bottle 1, the sample solution in the sampling bottle 1 is shaken manually or mechanically, and then the reagent bottle assembly is placed horizontally with the horizontal end surface 22 as the bottom surface. At this time, the reagent bottle assembly is composed of the sampling bottle 1, the liquid passage 3 and the filter bottle 2 from top to bottom. The sample solution in the sampling bottle 1 is filtered by the filter membrane 31 in the liquid passage 3 due to its own gravity and then enters the filter bottle 2. Then the reagent bottle assembly is placed upright and the bottle cap of the filter bottle 2 is opened. Finally, the filtered sample solution is obtained from the filter bottle 2.
[0041] Specifically, the liquid passage 3 includes an inner passage 32 integrally provided with the sampling bottle 1 and an outer passage 33 integrally provided with the filtering bottle 2, an inner step ring 321 is coaxially provided at one end of the inner passage 32 close to the outer passage 33, an outer step ring 331 is coaxially provided at one end of the outer passage 33 close to the inner passage 32, the inner step ring 321 is coaxially clamped in the outer step ring 331, and a filter membrane 31 is clamped between the end faces of the inner step ring 321 and the outer passage 33 facing each other.
[0042] The inner step ring 321 is clamped in the outer step ring 331 to achieve a stable connection between the inner passage 32 and the outer passage 33. The radial abutment between the inner step ring 321 and the outer step ring 331 increases the abutment surface between the inner step ring 321 and the outer step ring 331, thereby improving the sealing between the inner passage 32 and the outer passage 33.
[0043] Specifically, the sampling bottle 1 and the filtering bottle 2 are both formed by injection molding, and the sampling bottle 1 and the filtering bottle 2 are connected by welding.
[0044] In one embodiment, the welding method between the sampling bottle 1 and the filtering bottle 2 is any one of ultrasonic welding, laser welding, friction welding, high frequency welding, vibration welding, hot plate welding, hot air welding and spin welding.
[0045] As a further improvement, the inner bottom surface of the sampling bottle cover 11 is clamped with a sampling spoon 112 via a clamping block 111 .
[0046] By setting a sampling spoon 112 on the inner bottom surface of the sampling bottle cap 11, it is convenient to set the sampling bottle cap 11 on the sampling bottle 1 by screwing, snapping, etc. after sampling the feces sample through the sampling spoon 112, so as to realize the placement of the feces sample in the sampling bottle 1, thereby realizing the quick placement of the feces sample.
[0047] Example 2
[0048] Reference Figure 1 As shown, in order to achieve accurate addition of diluent and accurate acquisition of sample solution, this embodiment proposes an improvement based on embodiment 1. The sampling bottle 1 and the filtering bottle 2 are both made of transparent materials, and scale lines 4 are respectively provided on the outer sides of the sampling bottle 1 and the filtering bottle 2.
[0049] By setting scale lines 4 on the outer side of the sampling bottle 1 and making the sampling bottle 1 from a transparent material, the volume of the diluent added into the sampling bottle 1 can be determined by the scale lines 4 set on the sampling bottle 1 .
[0050] By setting scale lines 4 on the outer side of the filter bottle 2 and making the filter bottle 2 from a transparent material, the volume of the sample solution obtained in the filter bottle 2 can be determined by the scale lines 4 set on the filter bottle 2 when obtaining the sample solution in the filter bottle 2.
[0051] In order to improve the accuracy of obtaining the sample solution, as a further improvement, the mouth of the filter bottle 2 is set at one end of the filter bottle 2 close to the sampling bottle cap 11, and the two ends of the liquid passage 3 are respectively connected to one end of the sampling bottle 1 close to the sampling bottle cap 11 and one end of the filter bottle 2 close to the filter bottle cap 21, and the volume of the sampling bottle 1 is smaller than the volume of the filter bottle 2.
[0052] By setting the bottle mouth of the filter bottle 2 at the end of the filter bottle 2 close to the sampling bottle cap 11, the two ends of the liquid passage 3 are respectively connected to the end of the sampling bottle 1 close to the sampling bottle cap 11 and the end of the filter bottle 2 close to the filter bottle cap 21, so that when the diluent is added to the filter bottle 2, under the premise that the height plane of the added diluent is lower than the liquid passage 3, the diluent will not enter the filter bottle 2 through the liquid passage 3, thereby saving the diluent and ensuring the accurate addition of the diluent.
[0053] If the volume of the sampling bottle 1 is equal to or greater than the volume of the filtering bottle 2, when the volume of the sample solution in the sampling bottle 1 is equal to or greater than the volume of the filtering bottle 2, when obtaining the sample solution in the filtering bottle 2, part of the sample solution will enter the sampling bottle 1 through the liquid passage 3. At this time, the descending height of the height plane of the sample solution obtained according to the scale line 4 on the filtering bottle 2 is not only affected by the amount of sample solution obtained, but also by the reflux amount of the sample solution through the liquid passage 3, resulting in the inability to obtain the accurate volume of the sample solution.
[0054] By setting the volume of the sampling bottle 1 to be smaller than the volume of the filtering bottle 2, when the sample solution in the sampling bottle 1 reaches the volume of the sampling bottle 1, the sample solution completely enters the filtering bottle 2 and the reagent bottle assembly is placed upright, the height plane of the sample solution is lower than the liquid passage 3, and the sample solution will not enter the sampling bottle 1 through the liquid passage 3, thereby ensuring accurate acquisition of the sample solution.
[0055] In one embodiment, the volume of the sampling bottle 1 can be reduced by increasing the bottom thickness or wall thickness of the sampling bottle 1 so that the volume of the sampling bottle 1 is smaller than the volume of the filtering bottle 2 while ensuring that the two opposite ends of the sampling bottle 1 along the height direction are flush with the two opposite ends of the filtering bottle 2 along the height direction.
[0056] In one embodiment, the sampling bottle 1 and the filtering bottle 2 may be made of polyvinyl chloride (PVC), polypropylene (PP) or other materials.
[0057] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
