Further, the dividing part 20 is provided with a groove 201, and the groove 201 is formed by the inward depression of the surface of the dividing part 20. The partition 20 is rotatable relative to the cartridge 10 so as to bring about that the recess 201 can be located in the sample chamber 101 and the test chamber 102, respectively, i.e. the partition 20 has a rotational travel relative to the cartridge 10, at a first end of which the recess 201 is located in the sample chamber 101 and at a second end of which the recess 201, just located in the sample chamber 101, is located in the test chamber 102.

In the above configuration, the cartridge 10 and the partition 20 are provided, and in use, a user puts a specimen such as feces into the specimen chamber 101, the groove 201 is sampled by the specimen chamber 101, and the rotation of the partition 20 rotates the groove 201 from the specimen chamber 101 to the test chamber 102, so that a part of the specimen taken by the groove 201 is transported from the specimen chamber 101 to the test chamber 102, and the test chamber 102 is diluted and mixed, and then the sample is sampled for testing. In this way, due to the groove 201, when the specimen is transported from the sample cavity 101 to the inspection cavity 102, the amount of the specimen will not exceed the volume of the groove 201, so that the amount of the sample sampled from the sample cavity 101 and the amount of the detection substance under the microscope after dilution can be ensured, the interference caused by too large amount of the diluted specimen to the detection is reduced, and the correct and accurate judgment of the patient condition is realized.

The material of the case 10 may be transparent, so as to facilitate observation of the color and state of the specimen.

The above-mentioned recess 201 may be provided with only one or a plurality of recesses, for example, two recesses 201 are preferred, two recesses 201 are provided, one recess is located in the test chamber 102, the other recess is located in the test chamber 101, as shown in fig. 1, two recesses 201 are provided opposite to each other, which are a first recess and a second recess, so that when the same sample is tested twice, the first recess is located in the test chamber 101, the second recess is located in the test chamber 102, the first recess is rotated from the sample chamber 101 to the test chamber 102 after the first recess is sampled, the first sample is tested, at this time, the second recess is located in the sample chamber 101, the second sample can be simultaneously tested, after the first test is completed, the dividing part 20 is rotated, so that the second recess is rotated again to the test chamber, for the second test, and obviously, the sampling and the test can be simultaneously performed, thereby saving the test time and improving the test efficiency.

Because the recess 201 is located on the cavity wall of the sample cavity 101, the sample is not easy to enter the recess 201, so that in order to ensure that the amount of the sample in the recess 201 is enough, the sampling end of the sampling spoon 30 is provided with the stirring blade 302, and the stirring blade 302 is obliquely arranged relative to the axis of the through hole, as shown in fig. 1, in the stirring process, the stirring of the sample can be more uniform, and the sample can easily enter the recess 201, so that the amount of the sample in the recess 201 is ensured.

It should be noted that, after the sample is placed in the sample cavity 101, the sample may be put into the recess 201 by shaking the sampling cartridge or knocking the sampling cartridge.

Wherein, the sampling spoon 30 is rotatably connected with the first sealing cover 11, and the sampling spoon 30 can be directly rotatably connected with the first sealing cover 11; the sample cartridge may also be rotatably connected to the first sealing cover 11 through a transition piece, as shown in fig. 1, 2 and 5, and further includes a rotating head 31, where the rotating head 31 is rotatably connected to a through hole of the first sealing cover 11, and the sampling spoon 30 is fixedly connected to the rotating head 31. To facilitate rotation of the sampling ladle 30, the end of the swivel head 31 remote from the sampling ladle 30 may be provided with a handling structure, such as a cross-type structure.

The sampling specimen box further comprises a sealing block 40, the sealing block 40 is arranged in the testing cavity 102 in a sealing way, so that the testing cavity 102 forms a dilution cavity 1021 on the side where the groove 201 is located, and generally, the sealing block 40 is made of rubber, so that the dilution cavity 1021 is sealed by extrusion of the sealing block 40 and the testing cavity 102. Specifically, the sealing block 40 is provided with a sampling hole 401, and the sampling hole 401 penetrates through the sealing block 40 along the direction from the opening of the inspection chamber 102 to the bottom, so that a sampling needle enters the dilution chamber 1021 through the sampling hole 401 to sample.

In order to ensure the cleanliness of the sample, the sampling specimen box further comprises a sampling needle 41, the sampling needle 41 can be inserted into or pulled out of the sampling hole 401, the sampling needle 41 is a disposable needle, and when in use, a tester inserts the sampling needle into the sampling needle 41 for sampling and then pulls out together with the sampling needle 41 to move to a detection station.

The sampling hole 401 may be a wedge-shaped hole, the small end of which is located at one side of the dilution chamber 1021; the outer wall of the sampling needle 41 is wedge-shaped, which can be inserted into a wedge-shaped hole to ensure a seal at the sampling hole 401.

Further, the sampling needle 41 can extend into the dilution chamber 1021 when inserted into the sampling bore 401 to facilitate sampling.

Optionally, the sealing block 40 divides the test chamber 102 into a dilution chamber 1021 and a cavity 1022, and the sampling needle 41 is completely disposed in the test chamber 102, i.e. the end of the sampling needle 41 remote from the dilution chamber 1021 is disposed in the cavity 1022, so as to ensure the tightness of the entire test chamber 102.

Often there will be food residue in the sample, can influence the accuracy of testing result, in order to guarantee the accuracy of detection, sampling specimen-box still includes setting up in diluting the filter screen 42 in chamber 1021, and filter screen 42 can be supported by organic material or inorganic material, and filter screen 42 covers sample hole 401 and is located the one end of diluting chamber 1021 to when the sample needle sample, remain food residue in diluting chamber 1021. The filter screen 42 may be embedded in the sealing block 40, or may be connected to the sealing block 40 or the box body 10 by bonding or screw connection.

In the above embodiments, in order to dilute the sample in the dilution chamber 1021, the sampling cartridge is further provided with the dilution hole 50, and the dilution hole 50 may be provided in several ways as follows:

in the first mode, as shown in fig. 1-2, the dilution hole 50 is provided in the sealing block 40, and the dilution hole 50 penetrates the sealing block 40 in the bottom direction along the opening of the test chamber 102, i.e., when the second sealing cover 12 is opened, the outside is communicated with the dilution chamber 1021 through the dilution hole 50, or when the cavity 1022 is provided, the cavity 1022 is communicated with the dilution chamber 1021 through the dilution hole 50, so that when a specimen needs to be diluted, a diluent can be injected into the dilution chamber 1021 through the dilution hole 50.

Specifically, as shown in fig. 1, the dilution hole 50 includes an injection section 501 near the opening of the inspection chamber 102 and a flow guiding section 502 near the dilution chamber 1021, the flow guiding section 502 is communicated with the injection section 501, and the flow guiding section 502 is located above the groove 201 in the vertical direction, so that the specimen in the groove 201 is flushed more thoroughly by the flow guiding of the dilution liquid through the flow guiding section 502.

The inner wall of the groove 201 includes an inclined surface 2011, the inclined surface 2011 is located at one side close to the opening of the cavity, and one end of the inclined surface 2011 close to the opening of the cavity is inclined to the outside of the partition 20 than the other end, that is, one end of the inclined surface close to the opening of the cavity is inclined from the bottom of the groove 201 to the opening direction than the other end, at this time, the medium flow direction of the flow guiding section 502 is parallel to the inclined surface 2011, as shown in fig. 1, by adopting the structure, the diluent can be better flushed to the inner wall of the groove 201, and the specimen of the groove 201 is flushed more thoroughly. Of course, the groove 201 may not be provided with the inclined surface 2011.

In the second mode, as shown in fig. 5, the dilution hole 50 is disposed in the partition 20, one end of the dilution hole 50 is communicated with the outside of the cavity, and the other end is communicated with the groove 201, generally, the flow area of the dilution hole 50 is far smaller than the area of the inner wall of the groove 201, in this mode, the second sealing cover 12 can be directly fixedly connected or detachably connected with the box body 10, and generally no opening is needed, so that the structure of the sampling specimen box is simpler, and in this mode, the dilution hole 50 is directly communicated with the inner wall of the groove 201, so that the diluent can be mixed with the specimen more thoroughly.

In order to minimize external influences on the sample chamber 101 or the test chamber 102, in this manner, the dilution hole 50 includes a vertical section and a horizontal section, the vertical section being in communication with the recess 201 through the horizontal section.

At this time, since the recess 201 is in communication with the dilution hole 50, when the patient or the medical staff puts the stool into the sample chamber 101, if the recess 201 is located in the sample chamber 101, the stool may not be stirred yet and enter the recess 201, so that the components of the sample brought into the test chamber 102 by the recess 201 are uneven, and the judgment of the patient condition is affected.

In this way, the second sealing cover 12 is sealingly connected to the opening of the inspection cavity 102, the second sealing cover 12 may be fixedly connected to the box body 10, and the second sealing cover 12 is provided with a sampling port. At this time, the sampling specimen box can further comprise a membrane which is easy to break, the membrane is easy to break through a sampling needle and the like, the sampling port is used for the sampling needle to stretch into the inspection cavity 102, and the membrane is easy to break to seal the sampling port so as to seal the sampling port when the inspection is not performed, and therefore the tightness of the whole inspection cavity 102 is guaranteed.

It should be noted that, at this time, the second sealing cover 12 may also be non-fixedly connected to the box body 10, that is, the second sealing cover 12 is detachably connected to the box body 10, so that the second sealing cover 12 may open or cover the inspection cavity 102, especially when the sampling needle 41 is taken out, the second sealing cover 12 may be separated from the box body 10, so as to facilitate the taking out of the sampling needle 41.

Regardless of the manner in which the dilution hole 50 is formed, the second sealing cover 12 may be hinged to the case 10 in addition to the above-described structure, so that the second sealing cover 12 may be sealed to close or open the test chamber 102, and it is obvious that the hinged manner may facilitate injection of the diluent, especially when the dilution hole 50 is formed in the first manner.

Specifically, as shown in fig. 4, the sampling specimen cartridge further includes a bayonet 70 and a driving member 80, and the cartridge body 10 is provided with a driving hole 103; the end of the second sealing cover 12, which is far away from the hinge shaft, is provided with a buckle 121, and the bayonet 70 is movably arranged on the box body 10 along the direction of approaching or separating from the buckle 121 so as to be clamped with or separated from the buckle 121; the driving piece 80 is used for driving the bayonet 70 to move, and is opposite to the driving hole 103 along the axial direction of the driving hole 103, so that an operator can push the driving piece 80 to move the bayonet 70 only through the driving hole 103, the second sealing cover 12 is opened or buckled, and the first sealing cover 11 and the box body 10 are buckled in a common mode, so that a user can conveniently open the first sealing cover 11, the second sealing cover 12 is not easy to open, and the second sealing cover 12 is prevented from being opened and misplaced into the inspection cavity 102 when the user places a specimen.

Typically, the opening area of the driving hole 103 is small, and a special tool is required to extend the driving hole, for example, only a thinner thimble can extend the driving hole, so that the driving rod 80 is pushed.

Optionally, the axial direction of the driving hole 103 is perpendicular to the movement direction of the bayonet 70, the driving member 80 is slidably connected to the box body 10 along the axial direction of the driving hole 103, the driving member 80 is provided with a driving surface 801 inclined relative to the axial direction of the driving hole 103, the driving surface 801 abuts against the bayonet 70, and at the clamping position, the buckle 121 can be located between the driving member 80 and the clamping position of the bayonet 70 and the buckle 121, that is, the driving member 80 and the bayonet 70 form a wedge-shaped matching structure, so that the size of the box body 10 along the sliding direction of the bayonet 70 can be reduced, and the gripping of the sampling specimen box by an instrument can be facilitated. Of course, the axial direction of the driving hole 103 may be identical to the sliding direction of the bayonet 70, and the sliding direction of the driver 80 is identical to the sliding direction of the bayonet 70.

When the driving member 80 is provided, in order to facilitate the processing of the cartridge 10, the cartridge 10 includes a body 104 and a cover 105 that are connected to each other, the sample chamber 101 and the test chamber 102 may be disposed on the body 104, the driving hole 103 may be disposed on the cover 105, and the driving member 80 and the bayonet 70 may be movably mounted on the cover 105.

In general, the sampling specimen cartridge further includes a return spring, and the return spring may be disposed at the hinge shaft of the second sealing cover 12 and the cartridge body 10, and between the bayonet 70 and the cartridge body 10.

It should be noted that, the above-mentioned structure that the second sealing cover 12 can open or close the box body 10 can lock the second sealing cover 12 after the sampling is finished, so as to ensure the sealing of the inspection cavity 102, thereby preventing the diffusion of the odor in the sample and affecting the environment.

In addition, the third sealing cover 13 may be directly engaged with the case 10, and when the dilution hole 50 is provided in the partition 20, as shown in fig. 5, the sampling cartridge may further include a sealing plug 22, and the dilution hole 50 may be sealed with the partition 20 by the sealing plug 22.

In the above embodiment, when in use, firstly, the patient or medical staff opens the first sealing cover 11, uses the sampling spoon 30 to take a proper amount of specimen, and tightly covers the first sealing cover 11, so that the specimen can be sent into the working chamber, and it should be noted that when the dilution hole 50 is arranged on the sealing block 40, the groove 201 can be located in the sample cavity 101 or the testing cavity 102, or can be located in neither the sample cavity 101 nor the testing cavity 102; when the dilution hole 50 is provided in the partition 20, the groove 201 is not located in the sample chamber 101. Then, the operator fixes the sampling specimen box on the specimen box frame of the analyzer, and after pushing the sampling specimen box to a designated position, the operator can observe the color and the property of the fecal specimen. Then, advance sampling specimen-box to stirring position, as shown in fig. 1, rotate the rotating head 31, drive sampling spoon 30 rotation, stirring vane 302 above sampling spoon 30 stirs the sample, can realize the first mixing to former sample, after former sample misce bene, if recess 201 is not located sample cavity 101 this moment, then through rotating partition portion 20, make recess 201 rotate to sample cavity 101, at this moment, continue to rotate sampling spoon 30, make the recess 201 on the partition portion 20 be full of the excrement and urine sample after mixing in.

Then, the sampling cartridge is pushed onto the working position of the partition 20, and the fecal specimen in the rotation groove 201 of the partition 20 is transited into the test chamber 102. Then, the sampling cartridge is pushed onto the opening position of the second sealing cap 12, the driving member 80 is pushed down by the ejector pin through the ejector pin against the driving hole 103 as shown in fig. 4, the driving member 80 slides down, thereby pushing the bayonet 70 to move rightward, separating from the buckle 121, and opening the second sealing cap 12 under the action of the return spring.

At this time, the sampling specimen box is pushed onto the working position for adding the diluent, the diluent needle is used for aligning the diluent hole 50, the diluent is added into the diluent cavity 1021 after the diluent needle is pressed down, and the added diluent is used for eluting and uniformly mixing the fecal specimen in the groove 201 under the action of the hydraulic pressure, so that the fecal specimen is separated from the groove 201 and is fused with the diluent for the first time. Next, the sampling cartridge is advanced to the working position of the sampling needle, the sampling needle 41 is aligned with the sampling needle, and the sampling needle 41 mixes the feces with the diluent by repeating suction and pressure discharge.
