[0039] The adjustment component 29 also includes a second limiting rod 292 located in the storage box 21 and driving the limiting bar 293 to move along the straight groove 27. One end of the second limiting rod 292 passes through the straight groove 27 and is fixedly connected to the connecting rod 291. The second limiting rod 292 is fixedly connected with a limiting bar 293 for limiting the sampling unit 3, and the limiting bar 293 is located in the storage box 21; one side of the connecting rod 291 is fixedly connected with a first rack 294 that drives the connecting rod 291 to move along the straight groove 27, and the top of the first rack 294 is provided with an adjusting gear 295 that drives the first rack 294 and the second rack 296 to move, and the adjusting gear 295 is meshed with the first rack 294, and the top of the adjusting gear 295 is provided with a second rack 296 that drives the docking bar 298 to move, and the adjusting gear 295 is meshed with the second rack 296.

[0040] A rotating shaft 297 for limiting the adjusting gear 295 is horizontally penetrated on the adjusting gear 295, and the rotating shaft 297 is connected to the adjusting gear 295 by a torsion spring. The rotating shaft 297 is fixedly connected to the storage box 21, and one end of the second rack 296 is fixedly connected to a docking strip 298 for limiting the storage box 21, and the docking strip 298 is located in the second limiting groove 28; one end of the inner wall of the outer shell 31 is fixedly connected to a plurality of blocking plates 37 for sealing the outer shell 31, and the blocking plate 37 is provided with a sealing plate 38 for sealing the outer shell 31 and a second elastic member 39 for driving the sealing plate 38 to move along the inner wall of the blocking plate 37, the sealing plate 38 is slidably connected to the blocking plate 37, one end of the second elastic member 39 is fixedly connected to the sealing plate 38, and the other end of the second elastic member 39 is fixedly connected to the inner wall of the outer shell 31.

[0041] The sampling tube 32 is fixedly connected with an adjustment plate 310 for driving the sampling tube 32 to move along the inner wall of the shell 31. A third elastic member 311 is arranged between the adjustment plate 310 and the blocking plate 37 to push the adjustment plate 310 to reset the sampling tube 32. One end of the third elastic member 311 is fixedly connected to the adjustment plate 310, and the other end of the third elastic member 311 is fixedly connected to the blocking plate 37. The shell 31 is provided with a plurality of connecting grooves 312 for accommodating connecting ropes 313. The connecting grooves 312 are provided with connecting ropes 313 connecting the adjustment plate 310 and the sealing plate 38. Both ends of the connecting rope 313 extend out of the connecting grooves 312. One end of the connecting rope 313 is fixedly connected to the adjustment plate 310, and the other end of the connecting rope 313 is fixedly connected to the sealing plate 38. A through hole 314 is horizontally arranged on one side of the shell 31 to allow the output end of the first telescopic rod 14 to fit with the adjustment plate 310, and the through hole 314 is connected to the internal space of the shell 31.

[0042] It should be noted that: the output end of the first telescopic rod 14 is also fixedly connected to the magnet 17 , and one side of the adjustment plate 310 is also fixedly connected to the iron sheet 36 .

[0043] It should be noted that: a pressing rod 4 is horizontally provided on the protective shell 18 , and one end of the pressing rod 4 extends to the third limiting groove 19 and fits with the docking strip 298 .

[0044] Embodiment 1: Figure 1-Figure 10 As shown, in this embodiment, when it is necessary to take bacterial samples from the burn wound, the pressing rod 4 on the protective shell 18 is first pressed, so that the pressing rod 4 pushes one end of the docking strip 298 to gradually retract from the third limiting groove 19 to the second limiting groove 28, thereby releasing the lock between the storage box 21 and the protective shell 18, making it easier for the sampling personnel to pull out the storage box 21.

[0045] It should be noted that when one end of the docking strip 298 is gradually retracted from the third limiting groove 19 to the second limiting groove 28, the docking strip 298 pushes the second rack 296 to move, thereby driving the adjusting gear 295 meshing with the second rack 296 to rotate.

[0046] It should be noted that: when the docking strip 298 is fully retracted into the second limiting groove 28, the storage box 21 and the protective shell 18 are unlocked, so that the storage box 21 is pulled out. When the storage box 21 is gradually pulled out along the inner wall of the protective shell 18, the inner wall of the protective shell 18 limits the docking strip 298, so that the docking strip 298 is always located in the second limiting groove 28.

[0047] It should be noted that: when the storage box 21 is pulled out from the protective shell 18, the pressure on the pressing rod 4 is released. At the same time, since the adjusting gear 295 and the rotating shaft 297 are connected by a torsion spring, after the storage box 21 is pulled out from the protective shell 18, the force on the docking strip 298 is released, so that the adjusting gear 295 is reset under the drive of the torsion spring, and then the adjusting gear 295 drives the docking strip 298 to reset through the second rack 296, so that one end of the docking strip 298 extends out of the second limiting groove 28.

[0048] After the sampling personnel draw out the storage box 21, they place a plurality of sterilized sampling units 3 on the supporting block 25 in the receiving groove 22 opened at the top of the storage box 21, and then press the sampling unit 3 to compress the first elastic member 24, thereby driving the supporting block 25 and the sampling unit 3 to descend along the inner wall of the receiving groove 22, and press the docking strip 298 to retract the docking strip 298 into the second limiting groove 28, thereby driving the adjusting gear 295 to rotate through the second rack 296, and the adjusting gear 295 drives the first rack 294 to move, thereby driving the connecting rod 291 and the second limiting rod 292 to move along the straight groove 27, thereby driving the limiting strip 293 to move out of the first limiting groove 26, and limiting the sampling unit 3 entering the receiving groove 22, so as to avoid the situation that the first elastic member 24 is reset when the sampling personnel stops pressing the sampling unit 3, causing the sampling unit 3 to be pushed out of the receiving groove 22, and at the same time facilitating the sampling personnel to fill the sampling unit 3.

[0049] When the sampling unit 3 is filled, the docking strip 298 is continuously pressed, and the top of the storage box 21 is inserted into the protective shell 18, and the storage box 21 is pushed, so that the inner wall of the protective shell 18 limits the docking strip 298. When the third limiting groove 19 is connected with the second limiting groove 28, the force on the docking strip 298 is released, so that the adjusting gear 295 is reset under the action of the torsion spring, so that the adjusting gear 295 drives the first rack 294 and the second rack 296 to reset; the second rack 296 is reset so that one end of the docking strip 298 enters the third limiting groove 19, so that the storage box 21 is engaged with the protective shell 18 to ensure stable operation of the device; the first rack 294 is reset, driving the limiting strip 293 to move into the first limiting groove 26, thereby releasing the limit on the sampling unit 3, so that the force on the first elastic member 24 is released, and the sampling unit 3 is pushed to move along the inner wall of the accommodating groove 22 until the sampling unit 3 enters the sliding groove 12 from the docking groove 13.

[0050] When the sampling unit 3 enters the slide groove 12, the first telescopic rod 14 is started, so that the output end of the first telescopic rod 14 is fixedly connected to the iron sheet 36 fixedly connected to the adjustment plate 310 through the magnet 17, thereby pushing the adjustment plate 310 to move along the inner wall of the shell 31, so that the third elastic member 311 is compressed. Since the forces at both ends of the third elastic member 311 are balanced, the first telescopic rod 14 pushes the sampling unit 3 to move along the slide groove 12.

[0051] It should be noted that when the output end of the first telescopic rod 14 is fixedly connected to the iron sheet 36 fixedly connected to the adjustment plate 310 through the magnet 17 , the output end of the second telescopic rod 16 is also fixedly connected to the iron sheet 36 through the magnet 17 .

[0052] When the output end of the first telescopic rod 14 continues to extend to push the sampling unit 3 to one end of the slide groove 12, the inner wall of the slide groove 12 limits the sampling unit 3, causing the output end of the first telescopic rod 14 to squeeze the adjustment plate 310, so that the third elastic member 311 is compressed, so that the adjustment plate 310 drives the sampling tube 32 to move along the inner wall of the shell 31 toward the blocking plate 37.

[0053] When the adjusting plate 310 drives the sampling tube 32 to move along the inner wall of the outer shell 31 toward the blocking plate 37, the adjusting plate 310 pulls the connecting rope 313. At this time, the force on the second elastic member 39 increases, so that the connecting rope 313 pulls the sealing plate 38 to gradually retract the blocking plate 37, thereby opening the outer shell 31, so that the liquid sampling gun head 33 at one end of the sampling tube 32 extends out of the outer shell 31, making it convenient for the sampling personnel to sample bacteria per unit area of ​​the burn wound.

[0054] When the liquid sampling gun head 33 extends out of the shell 31, the second telescopic rod 16 is started, so that the output end of the second telescopic rod 16 pulls the first limit rod 35 and the piston 34 to move along the inner wall of the sampling tube 32, thereby sampling the pus and effusion within a unit area of ​​the burn wound. When the output end of the second telescopic rod 16 moves out of the shell 31, the sampling is completed.

[0055] When sampling is completed, the first telescopic rod 14 is started, so that the output end of the first telescopic rod 14 is gradually retracted, so that the forces on the second elastic member 39 and the third elastic member 311 are reduced, so that the second elastic member 39 and the third elastic member 311 respectively push the sealing plate 38 and the adjustment plate 310 to reset, thereby sealing the sampling tube 32 in the housing 31 to prevent dust and bacteria in the air from entering the sampling tube 32, which would lead to inaccurate detection results.

[0056] It should be noted that one side of the bottom end of the limiting plate 111 is connected to the inner wall of the sampling port 110 via a hinge, and the other side of the bottom end of the limiting plate 111 is in contact with the inner wall of the sampling port 110 , and a torsion spring is provided on the hinge.

[0057] When the first telescopic rod 14 drives the sampling unit 3 to reset, the sampling personnel flips the limit plate 111, and the limit plate 111 rotates under the action of the hinge. At this time, the torsion spring is compressed, thereby opening the sampling port 110, and the sampling unit 3 after sampling is taken out from the sampling port 110. After taking out the sampling unit 3, the limit plate 111 is loosened, and the torsion spring is relieved of the force, so that the limit plate 111 is reset under the action of the torsion spring, thereby closing the sampling port 110.

[0058] It should be noted that when the sampling unit 3 that has completed sampling is taken out, the first elastic member 24 will push the new sampling unit 3 from the docking groove 13 into the sliding groove 12 to wait for sampling.

[0059] At the fire scene, the sampling personnel load the sampling unit 3 into the storage box 21 in advance, so that when sampling at the fire scene, the sampling personnel only need to carry this device, and do not need to carry sampling test tubes, cotton swabs, liquid sampling gun heads 33 and other tools to sample bacteria from the patient's burn wound, which effectively reduces the workload of the sampling personnel when sampling at the fire scene and reduces the sampling burden of the sampling personnel.

[0060] When sampling, the sampling personnel hold the protective shell 18 to manually adjust the sampling angle of the liquid sampling gun head 33, so that the liquid sampling gun head 33 is aimed at the pus and effusion produced in the burn wound, and then the second telescopic rod 16 is started to take samples, thereby improving the stability of the device during sampling, so that the liquid sampling gun head 33 can sample pus and effusion without contacting the burn wound, effectively avoiding the situation in which the sampling personnel are in a panic at the fire scene. When the sampling personnel pull the piston 34 in the sampling tube 32, the sampling tube 32 may shake, causing the sampling tube 32 to contact the burn wound and cause pain or discomfort to the burn patient.

[0061] After sampling is completed, the output end of the first telescopic rod 14 retracts, and the third elastic member 311 drives the sampling tube 32 to reset, thereby sealing the obtained sample in the outer shell 31 to prevent dust and bacteria in the air at the fire scene from entering the sampling tube 32, thereby improving the accuracy of bacteria extracted from the burn wound and facilitating subsequent medication by medical staff.

[0062] After the sampling is completed, the sampling unit 3 is automatically filled by the first elastic member 24, so that after the sampling personnel completes the sampling of a burn wound, they can quickly sample the next unit area of ​​the burn wound without replacing the liquid sampling gun head 33 and the sampling tube 32, thereby speeding up the sampling speed and shortening the sampling cycle.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
