Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] See also Figure 1-Figure 7 , this embodiment provides the following technical solutions:
[0032] like Figure 1-Figure 3As shown, a fecal occult blood detection kit comprises: a reagent bottle 1 and a test paper card 4, the test paper card 4 is provided with a plurality of stool test areas 401 and a plurality of sample dropping areas 402 arranged side by side, the sample dropping areas of the test paper card 4 are connected, a thread groove 101 is provided at the inner mouth of the reagent bottle 1, a thread ring 205 is installed on the inner thread of the thread groove 101, a top cover 2 is fixedly installed on the upper surface of the thread ring 205, a dropper 201 is fixedly installed on the upper surface of the top cover 2, a connecting column 202 is fixedly installed on the lower surface of the top cover 2, a sampling comb 203 is fixedly installed on the lower surface of the connecting column 202, a sample inlet 204 is provided on the outer surface of the connecting column 202, the sample inlet 204 is connected to the dropper 201, a blocking component 3 is slidably installed in the dropper 201, and the blocking component 3 can block and seal the sample inlet 204.
[0033] The inside of the threaded ring 205 of the top cover 2 is a tapered slope surface.
[0034] The reagent bottle 1 is a transparent soft bottle.
[0035] The sampling comb 203 and the connecting column 202 can be threadedly inserted into the reagent bottle 1 along with the top cover 2 .
[0036] Through the design of the blocking component 3, the dropper 201, the connecting column 202, the sample inlet 204 and the sampling comb 203, when in use, the top cover 2 can be unscrewed from the inner thread of the reagent bottle 1, and then the blocking component 3 can be pushed down to block and seal the sample inlet 204, and then the diluted liquid medicine can be poured into the reagent bottle 1. Then the staff can hold the top cover 2 and drive the sampling comb 203 at one end to sample the stool. After sampling, the sampling comb 203 is inserted into the reagent bottle 1 and the threads between the top cover 2 and the reagent bottle 1 are tightened and sealed. Then the staff can shake the bottle body to dilute the stool sample with the diluent liquid inside. During the dilution process, the staff can observe the stool sample through the transparent reagent bottle 1. Observe the dilution progress until the testable dilution value is reached, then push up the blocking component 3 to start the blocking and sealing state of the sample inlet 204, then turn the reagent bottle 1 over, and align the dropper 201 with the sample dropper area on the test paper card 4, then squeeze the reagent bottle 1 to allow the diluted stool sample inside to enter the sample inlet 204, and the stool sample entering the sample inlet 204 will pass through the blocking component 3 and drip out of the dropper 201.

[0042] The outer surfaces of the two sets of guide rail blocks 303 are fixedly mounted with push-pull rings 302 , and the push-pull rings 302 are slidably mounted on the outer surface of the dropper 201 .
[0043] Through the design of the blocking tube 301, the push-pull ring 302 and the guide block 303, when the sample needs to be sealed in the reagent bottle 1, the staff can push down the push-pull ring 302 and drive the blocking tube 301 to slide downward in the dropper 201 through the guide block 303, so that the blocking tube 301 can slide down and seal the sample inlet 204, that is, the sealing operation of the reagent bottle 1 is achieved, and the staff can shake the bottle body to dilute the stool sample. After dilution, the push-pull ring 302 can be pushed up to drive the blocking tube 301 to slide upward and start the blocking and sealing state of the sample inlet 204, so that the staff can squeeze the reagent bottle 1 to squeeze the sample out of the dropper 201.

[0045] Through the design of the limiting grooves 206 and the plastic convex balls 304, when the push-pull ring 302 is pushed up and down to drive the blocking tube 301 to seal and expand the sample inlet 204, the push-pull ring 302 will drive the internal plastic convex balls 304 from the current limiting grooves 206 to be engaged into another set of limiting grooves 206, so that each push up or push down of the push-pull ring 302 has a limiting effect, thereby preventing the push-pull ring 302 from detaching from the current position and causing sample leakage.
[0046] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when in use, the top cover 2 can be unscrewed from the inner thread of the reagent bottle 1, and then the push-pull ring 302 is pushed down and the blocking tube 301 is driven to slide downward in the dropper 201 through the guide block 303, so that the blocking tube 301 can slide down and seal the sample inlet 204, that is, the sealing operation of the reagent bottle 1 is achieved, and then the diluted liquid is poured into the reagent bottle 1, and then the staff can hold the top cover 2 and drive the sampling comb 203 at one end to sample the stool, and then The sampling comb 203 is inserted into the reagent bottle 1 and the threads between the top cover 2 and the reagent bottle 1 are tightened and sealed. Then the staff can shake the bottle body to dilute the stool sample with the diluent inside. After dilution, the reagent bottle 1 can be turned over and the dropper 201 is aligned with the sample dropping area on the test paper card 4. Then the reagent bottle 1 can be squeezed to make the diluted stool sample inside enter the sample inlet 204.
