When the sputum sampling and detecting device is used, the sampling rod 22 is inserted into the sampling tube 21, the lower end of the sampling rod 22 penetrates out of the through hole to assemble the sampling tube 2, and the bottom surface of the extrusion block 23, the top surface of the mold penetrating cone 242 and the inner wall of the sampling tube 21 are combined to form a sputum collecting cavity. During collection, the sampling rod 22 is inserted into sputum in a collection container, the sampling rod 22 is pulled upwards, the sputum is extracted into a sputum collection cavity, the radius of the sampling tube 21 is fixed due to the fixed length of the connecting rod 241, the volume of the sputum collection cavity is the same, therefore, the volume of a sputum sample collected by the collection tube 2 is the same, the quantitative collection effect is achieved, the collection tube 2 filled with the sputum is inserted into a containing cavity, the sampling rod 22 is pressed again to puncture the sealing membrane 12, the main container sealing tube 1 is shaken to mix the sputum with diluent to form a test sample, the sampling rod 22 is continuously pressed to enable the test sample to enter the test paper sealing tube 25, the test sample and the test paper 3 are in contact reaction, and after the test paper 3 reacts with the test sample, the test paper 3 can be taken out to observe the detection result.
The sampling tube 21 and the sampling rod 22 are combined to form a sampling tube 2, and the purpose of sampling sputum samples is achieved by pulling the sampling rod 22. When the sputum sample is collected, the lower ends of the film penetrating structure 24 and the sampling tube 21 are inserted into the sputum sample, the bottom surface of the extrusion block 23 is flush with the outer edge of the through hole, the sputum sample is attached to the film penetrating structure 24, and when the sampling rod 22 is pulled, the sputum sample is brought into the sampling tube 21 by the top surface of the film penetrating cone 242 and stored in the sputum collection cavity.

Some devices for detecting sputum are currently available, but the waterproof membrane of such devices is used to seal the test strip, which reacts with the solution in the device immediately after the waterproof membrane is pierced. If the patient makes an error in the detection operation, the sputum is not mixed with the diluent, but the waterproof membrane is directly pierced, and the test paper reacts with the solution in the device immediately, so that a larger error occurs in the detection. In addition, there are also some devices for detecting sputum to separate test paper and diluent through a waterproof membrane, but the problem that a patient may falsely puncture the waterproof membrane to cause uneven mixing of sputum and diluent, resulting in a large error in detection cannot be solved.
Further, the collecting tube 2 further comprises a holding block 221, a closing block 222 and a plurality of blocking blocks 223;
the holding block 221 is disposed at the upper end of the sampling rod 22, the closing block 222 and the blocking blocks 223 sequentially protrude from top to bottom from the outer wall of the sampling rod 22, an avoidance cavity adapted to the closing block 222 is disposed at the inlet of the accommodating cavity, and the blocking blocks 223 are adapted to the accommodating cavity.

The closing block 222 is matched with the avoidance cavity, plays a limiting role, and prevents the problem that the sputum sampling and detecting device is damaged because the detecting personnel or the patient still continuously press after the membrane penetrating structure 24 is contacted with the bottom of the diluent accommodating part 112. The blocking piece 223 plays a role in blocking the flow of air, so that when a detector or a patient pulls the sampling rod 22 upwards, negative pressure is formed in the sampling tube 21, and a sputum sample is adsorbed and enters the sampling tube 21.
Further, the test paper sealing tube 25 and the limiting block 26 are also included;
The test paper 3 is placed in the test paper sealing tube 25, a diluent inlet 252 is arranged at one side of the lower end of the test paper sealing tube 25, which is close to the connecting channel 14, a partition lug is arranged below the diluent inlet 252 and protrudes from the outer wall of the test paper sealing tube 25, and a positioning baffle 253 is arranged at the upper end of the test paper sealing tube 25;

when the test strip sealing tube 25 is completely inserted into the test strip chamber 13, the diluent inlet 252 is in communication with the connecting channel 14.
With this structure, after the test paper sealing tube 25 passes through the limiting block 26 and the mounting hole 251, the positioning baffle 253 and the positioning protruding block 261 interfere with each other, so that the test paper sealing tube 25 cannot completely enter the test paper cavity 13, and the diluent inlet 252 and the connecting channel 14 are staggered, so that a problem that when the test tube 1 is shaken, a sputum sample and a diluent are not completely mixed and enter the test paper sealing tube 25 in advance through the diluent inlet 252 and the connecting channel 14, and further the test paper 3 reacts with the sputum sample which is not completely diluted is avoided, and a larger error occurs in a test result. After the sputum sample and the diluent shake evenly, a detector or a patient removes the limiting block 26, so that the test paper sealing tube 25 completely enters the test paper cavity 13, the diluent inlet 252 is communicated with the connecting channel 14, and the diluted sputum sample enters the test paper sealing tube 25 through the connecting channel 14 and the diluent inlet 252 and is in contact reaction with the test paper 3. The separation lug is matched with the test paper cavity 13, so that an isolation effect is achieved, and a test sample is prevented from entering the test paper cavity 13 in advance.
Preferably, a clamping block 211 is provided at the upper end of the sampling tube 21, the clamping block 211 protrudes from the outer wall of the sampling tube 21, and the clamping block 211 abuts against the positioning baffle 253.
When the limiting block 26 is not taken out, the test paper sealing tube 25 is erected by the positioning protruding block 261, so that the test paper sealing tube 25 cannot completely enter the test paper cavity 13, meanwhile, the positioning baffle 253 is propped against the clamping block 211, the positioning baffle 253 supports the sampling tube 21, so that the extrusion block 23 and the penetrating structure 24 cannot completely enter the diluent accommodating part 112, a test sample cannot flow through the connecting channel 14, the problem that the sampling tube 21 continues to move downwards to cause the incompletely diluted sputum sample to be extruded into the test paper cavity 13 is solved, and the situation that the test paper 3 reacts with the incompletely diluted sputum sample due to incorrect operation of a user is further prevented.
In a specific embodiment, the test paper further comprises a sponge 27, the sponge 27 is disposed at the diluent inlet 252, and the lower end of the test paper 3 is in contact with the sponge 27.
The sponge 27 plays a role in absorbing the diluted sputum sample, and the diluted sputum sample enters the test paper sealing tube 25 and is absorbed by the sponge 27. The diluted sputum sample gradually comes into contact with the test paper 3 through the sponge 27 by capillary phenomenon. In addition, the sponge 27 can adsorb sticky foreign matters and impurities in the sputum, and the sticky foreign matters and impurities in the sputum are prevented from affecting the test result.
