[0035] see Figure 1-4, the present invention provides a technical solution: a cerebrospinal fluid extraction tool, including a drainage needle 5, and also includes a clamping assembly 4 that is convenient for medical staff to apply force to prick the needle and an intracranial pressure measurement assembly for measuring the patient's intracranial pressure 8;
[0036] The clamping assembly 4 includes two splints 401 that are hinged together and an elastic pad 402 that is arranged on the inside of the splint 401 and fits the outer wall of the drainage needle 5 to increase friction. The outside of the splint 401 is provided with a finger extrusion block 403, which needs to be emphasized here Yes, when the hand of the medical staff squeezes the fingers to squeeze the block 403, the splint 401 feels the pressure exerted by the hand of the medical staff, and transmits the pressure to the elastic pad 402, here we can see that the elastic pad 402 and the drainage needle 5 There is a...

[0048] Such as Figure 5 As shown, the difference from the first embodiment is that the cerebrospinal fluid processing assembly 9 of this embodiment is a test tube 10 connected to the end of the drainage needle, and the cerebrospinal fluid can be directly stored through the test tube 10, which is convenient for medical staff to send it directly to the laboratory. Section for testing.
[0049] A scale is provided on the test tube 10 to control the extraction amount, so as to ensure the detection effect and reduce waste.
