Throughout the drawings, the same elements are indicated by the same or similar reference numerals.

[0023] <Overall Composition>

[0024] A disposable fecal sample quantitative dispenser according to an exemplary embodiment of the present invention includes: a tube cap 1, a fecal collection tube 2, a connector 3, a filter pad 4, a protective cover 5, a liquid dispensing tube 7, a stirring rod 8, and a collection block 6.

[0025] The cap 1 is used to detachably seal the dropper opening 10 at the lower end of the collection tube 2, for example, by means of an internal thread. Preferably, a filter pad 4 is also provided on the bottom wall of the cavity of the collection tube 2, covering the inlet side of the dropper opening 10, for filtering the sample solution to be flowed into the dropper opening 10.

[0026] The stool collection tube 2 is made of flexible materials such as plastic (e.g., medical-grade PP, i.e., polypropylene) in a cylindrical shape similar to a syringe, used to hold stool samples and mix stool samples with diluents. By squeezing the tube with their fingers and applying pressure from the outside, the sample solution can be dripped from the dropper opening 10.

[0027] In some embodiments, such as Figure 2As shown, the dropper opening 10 is configured as a tube extending distally through the bottom wall of the collection tube 2. As an example, to obtain a quantitative sample, such as a drop volume of 40 μL, the tube dimensions can be an outer diameter of 2.6 mm, an inner diameter of 2 mm, and an axial length of 12 mm. However, it is not limited to this; the inner diameter can also be configured as a tapered orifice that expands from the root of the collection tube 2 on the cavity side towards the dropper outlet side, while ensuring an inner diameter of 2 mm on the dropper outlet side.

[0028] The upper end of the collection tube 2 is sealed and installed at the lower end 71 of the liquid filling tube 7, for example, by screwing on external and internal threads respectively. The liquid filling tube 7 is used to pre-fill the diluent through the soft capsule 74, and is sealed to the inner wall 72 of the connecting part 75 located between the lower end 71 and the soft capsule 74, or for mounting and connecting the soft capsule 74, using the connector 3 to seal the diluent. In addition, the outer wall 73 of the connecting part 75 is configured to guide the protective cover 5 (see...). Figure 5 The fitting part is fastened to it to prevent the soft capsule 74 from being subjected to undesirable external forces.

[0029] like Figure 3 As shown, the connector 3 is configured as a cover structure. The outer peripheral wall 35 on the side of the bottom wall 32 serves as an encapsulation wall for mating with the inner wall 72 of the connecting part 75. The port wall 31 on the side of the outer peripheral wall 35 near the opening end serves as an operating part for inserting the connector 3 into the connecting part 75. Preferably, a stepped portion is formed between the outer peripheral wall 35 and the port wall 31, which is adapted to the structure between the connecting part 75 and the lower port 71, to facilitate positioning and locking during insertion. The outer diameter of the port wall 31 is smaller than the inner diameter of the upper end of the collection tube 2, and the length of the port wall 31 is suitable for docking with or extending into the upper end of the collection tube 2, so as to guide the diluent from the soft bag 74 into the collection tube 2. For this purpose, a channel 30 is also formed on the inner side of the bottom wall 32 to allow the diluent to flow from the outside to the inside through the bottom wall 32, and a corresponding opening rod 33 is formed on the outer side of the bottom wall 32 for temporarily sealing the channel 30. Preferably, a recessed groove (such as a conventional notch or fracture line, collectively referred to as a recessed groove) is provided at the base of the opening rod 33 where it connects to the bottom wall 32 to facilitate breakage. In this way, the opening rod 33 can be broken off from the base by hand to connect the soft sac 74 with the channel 30 and the stool collection tube 2.

[0030] Furthermore, a base 34 for engaging the stirring rod 8 is formed on the inner side of the bottom wall 32 of the connector 3. Figure 6 As shown, one end of the stirring rod 8 is fitted into the base 34; a collection block 6 can be additionally provided on the other end of the stirring rod 8, with multiple edges formed on the lower end of the collection block 6 to facilitate sample collection. However, it is not limited to this, and a collection block 6 with multiple edges can also be integrally formed on the lower end of the stirring rod 8.

[0031] Of course, stirring rod 8, collecting block 6, filter pad 4, and tube cap 1 can also be added separately as needed.

[0032] <Action Example>

[0033] Using robotic arms, the protective cover 5 was fastened to... Figure 4 The outer wall 73 of the liquid filling tube 7 shown clamps the protective cover 5 and inverts the liquid filling tube 7 with the lower port 71 facing upward. A predetermined amount of diluent is added to the soft bag 74. Then, the outer peripheral wall 35 is inserted and fitted into the inner wall 72 of the connecting part 75 by holding the port wall 31 to complete the pre-sealing of the diluent.

[0034] Insert the stirring rod 8 into the base 34 of the connector 3, and install the collection block 6 on the other end of the stirring rod 8. While inserting the stirring rod 8 into the cavity of the collection tube 2 equipped with the filter pad 4, screw the lower end 71 of the liquid addition tube 7 to the upper end of the collection tube 2. Screw the tube cap 1 to the dropper port 10 at the lower end of the collection tube 2. In this way, the preparation of the quantitative sampler is completed.

[0035] When using the device, unscrew the collection tube 2, hold the protective cover 5, and use the stirring rod 8 or even the collection block 6 to collect a stool sample. After screwing the collection tube 2 back on, the quantitative sampler can be placed flat or vertically in the tube rack for later use.

[0036] During testing, the protective cover 5 can be removed, and the opening rod 33 can be broken through the soft bag 74 to allow the diluent to flow into the stool collection tube 2 through the channel 30. The sample is then thoroughly mixed by shaking. A stirring rod 8 can also be used to enhance the mixing of the diluent and the stool sample. Squeezing the stool collection tube 2 allows a quantitative sample to be dispensed from the dropper opening 10. For example, coarse particles can be filtered out through the filter pad 4 and dispensed quantitatively (e.g., 40-50 μL).

[0037] The present invention achieves the following technical effects: the sample diluent is individually packaged, facilitating assembly and operation; the sealed operation prevents direct or indirect contamination. Compared with existing samplers, it is simpler to operate and more hygienic; it can filter larger sample particles and accurately dispense the sample.

[0038] In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified. Unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Although the present invention has been described with reference to various specific embodiments, it should be understood that modifications can be made within the spirit and scope of the described inventive concept. Therefore, it is intended that the present invention be limited to the described embodiments but will have the full scope defined by the language of the appended claims.
