[0030] As an implementation method in this embodiment, such as Figures 4 to 10 As shown, the aseptic adjustment component 7 includes a triangular base 71 fixedly connected to the end of the main body 2. A telescopic tube 72 is sleeved on the outer surface of the triangular base 71. One end of the telescopic tube 72 is fixedly connected to the end of the main body 2, and the other end of the telescopic tube 72 is fixedly connected to the surface of the infusion tube 9. An elastic sealing ring 73 is fixedly connected to the surface of the other end of the infusion tube 9. The other end of the elastic sealing ring 73 is sleeved on the surface of the fixed tube 61.

A connecting frame 79 is inserted into the end of the column 77. The axis of the connecting frame 79 is sleeved on the surface of the tubing 68. A second spring 78 is sleeved on the surface of the column 77. One end of the second spring 78 is fixedly connected to the surface of the connecting frame 79, and the other end of the second spring 78 is fixedly connected to the surface of the rotating block 76. When fixedly connected to the fixed tube 6... The elastic sealing ring 73 on the main body 1 begins to fit tightly against the patient's surface, isolating the outside air and creating an isolated environment to protect the patient from external bacterial infection. At the same time, as the elastic sealing ring 73 fits tightly, the telescopic tube 72 fixedly connected to the end of the main body 2 moves synchronously, making it easy to adjust the infusion tube 9 to the optimal torsion angle and to ensure the tight fit of the elastic sealing ring 73. Simultaneously, as the telescopic tube 72 moves, the rotating shaft 75 rotatably connected to the bottom of multiple connecting seats 74 begins to rotate in the torsion direction of the telescopic tube 72. At this time, the multiple connecting seats 74 are fixedly connected to the triangular base 71 and remain stable. As the rotating shaft 75 rotates, the rotating block 76 fixedly connected to the bottom of the rotating shaft 75 begins to drive the column 77 to move together. As the infusion tube 9 rotates, the connecting frame 79 rotates along with it. At the same time, when the connecting frame 79 rotates, the second spring 78 between the connecting frame 79 and the rotating block 76 is compressed and contracts to provide support, so that the sampling needle 62 can be in the optimal sampling angle.
[0031] As an implementation method in this embodiment, such as Figures 3 to 12As shown, the pretreatment centrifuge assembly 8 includes a slanted push plate 81 fixedly connected to the output end of the electric push rod 3. The slanted push plate 81 is slidably connected inside the main body 2. Multiple rotating bases 82 are mounted on the top of the slanted push plate 81. A spiral rod 83 is rotatably connected inside the rotating base 82. A friction wheel 84 is fixedly connected to one end of the spiral rod 83. The friction wheel 84 is in rolling connection with the inside of the main body 2. The other end of the spiral rod 83 is slidably connected to the main body 2. A trigger rod 85 is fixedly connected to one end surface of the slanted push plate 81. A reagent chamber 86 is fixedly connected to the top of the main body 2. The bottom opening of the reagent compartment 86 is on the same vertical line as the trigger rod 85. A liquid outlet pipe 87 is fixedly connected to one end of the main body 2, and a centrifuge temperature control box 88 is fixedly connected to the other end of the liquid outlet pipe 87. A tube carrier 89 is rotatably connected inside the centrifuge temperature control box 88, and a sterile tube 810 is inserted into the tube carrier 89. When the electric push rod 3 starts operating, the inclined push plate 81 fixedly connected to the output end of the electric push rod 3 moves upward a specified distance inside the main body 2. During the upward movement of the inclined push plate 81, multiple rotating bases 82 drive multiple... The spiral rod 83 moves upwards together, at which point the friction wheel 84, fixedly connected to one end of the spiral rod 83, contacts the inner wall of the main body 2. The friction wheel 84 then begins to rotate, and subsequently, the spiral rod 83, fixedly connected to one end of the friction wheel 84, rotates together. The rotating spiral rod 83 then agitates the cerebrospinal fluid. Simultaneously, as the inclined push plate 81 moves, the trigger rod 85, fixedly connected to the surface of the inclined push plate 81, moves upwards together. The trigger rod 85 then contacts the bottom of the reagent chamber 86 and pushes against the interior of the reagent chamber 86. According to the contact distance of the trigger rod 85, an appropriate amount of reagent is dropped from the reagent chamber 86 into the cerebrospinal fluid. At the same time, the screw rod 83 stirs the cerebrospinal fluid, accelerating the reaction between the cerebrospinal fluid and the reagent. Then, the inclined push plate 81 begins to descend. When the inclined push plate 81 descends to the same height as the outlet tube 87, it stops. The mixed cerebrospinal fluid is pumped through the outlet tube 87 into the centrifuge temperature control box 88, and then evenly transported into multiple sterile tubes 810 in the carrier tube container 89. Subsequently, the carrier tube container 89 begins to rotate and centrifuge, reducing the interference of impurities in the cerebrospinal fluid and improving the accuracy of the detection.
[0032] The working principle of the technical solution provided by this invention is as follows: In use, the sampling needle 62 is first inserted into the lumbar spine for puncture. The sampling needle 62 penetrates into the skin. The pushed sampling needle 62 moves the fixation frame 64 together with it in the fixation tube 61. As the fixation frame 64 moves, the first spring 65, which is fixedly connected to the end of the fixation frame 64, begins to contract in the fixation tube 61. When the sampling needle 62 breaks through the dura mater, the pressure inside the cerebrospinal fluid immediately increases. At the same time, as the resistance at the tip of the sampling needle 62 decreases, the first spring 65 slowly rebounds, causing the sampling needle 62 to instantly disengage from the push. This avoids the sampling needle 62 from being inserted too deeply. At the same time, multiple miniature pressure sensors 63 installed at the end of the sampling needle 62 detect the internal pressure of the cerebrospinal fluid. The cerebrospinal fluid flows through the sampling needle 62 into the electromagnetic regulating valve 66, and then through the one-way valve 67 at one end of the electromagnetic regulating valve 66 into the tubing 68. At this time, the flow rate sensor 69 in the tubing 68 detects the flow rate of the cerebrospinal fluid and then judges the patient's brain pressure. When the pressure exceeds the safe range, the sampling channel diameter is automatically adjusted to ensure the flow rate and reduce the occurrence of risks.
[0033] When the sampling needle 62 is inserted into the lumbar spine, the aseptic adjustment component 7 begins to operate. At this time, the elastic sealing ring 73, fixedly connected to the fixing tube 61, begins to fit tightly against the patient's surface, isolating the outside air and creating an isolated environment to protect the patient from external bacterial infection. Simultaneously, as the elastic sealing ring 73 fits tightly, the telescopic tube 72, fixedly connected to the end of the main body 2, moves synchronously, facilitating the adjustment of the infusion tube 9 to the optimal torsion angle and ensuring a tight fit of the elastic sealing ring 73. Furthermore, as the telescopic tube 72 moves, the multiple connecting seats rotate... The bottom shaft 75 of 74 begins to rotate in the torsional direction of the telescopic tube 72. At this time, multiple connecting seats 74 are fixedly connected to the triangular base 71 and remain stable. As the shaft 75 rotates, the rotating block 76 fixedly connected to the bottom of the shaft 75 begins to drive the column 77 to move together. As the infusion tube 9 rotates, the connecting frame 79 rotates along with it. At the same time, when the connecting frame 79 rotates, the second spring 78 between the connecting frame 79 and the rotating block 76 is compressed and retracts to provide support, so that the sampling needle 62 can be in the optimal sampling angle.
[0034] After the cerebrospinal fluid (CSF) is delivered to the main body 2 through the tubing 68, the pretreatment centrifugation assembly 8 starts operating. After the CSF is sampled, based on the CSF sample volume, the electric push rod 3 is operated to move the inclined push plate 81, which is fixedly connected to the output end of the electric push rod 3, upward a specified distance inside the main body 2. During the upward movement of the inclined push plate 81, multiple rotating bases 82 carry multiple spiral rods 83 upward together. At this time, the friction wheel 84, which is fixedly connected to one end of the spiral rod 83, comes into contact with the inner wall of the main body 2, and then the friction wheel 84 begins to rotate. Subsequently, the spiral rod 83, which is fixedly connected to one end of the friction wheel 84, rotates together. At this time, the rotating spiral rod 83 agitates the CSF. Simultaneously, as the inclined push plate 81 moves, the solid... The trigger rod 85, which is fixedly connected to the surface of the inclined push plate 81, moves upward together with the trigger rod 85. Then, the trigger rod 85 contacts the bottom of the reagent chamber 86 and pushes against the inside of the reagent chamber 86. According to the contact distance of the trigger rod 85, an appropriate amount of reagent falls into the cerebrospinal fluid from the reagent chamber 86. At the same time, the spiral rod 83 stirs, accelerating the reaction between the cerebrospinal fluid and the reagent. Then, the inclined push plate 81 begins to descend. When the inclined push plate 81 descends to the same height as the outlet pipe 87, it stops. The mixed cerebrospinal fluid is pumped into the centrifuge temperature control box 88 through the outlet pipe 87, and then evenly transported into multiple sterile tubes 810 in the tube carrier 89. Subsequently, the tube carrier 89 begins to rotate and centrifuge, reducing the interference of impurities in the cerebrospinal fluid and improving the accuracy of the detection.
