[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.

Abstract

The invention relates to a cerebrospinal fluid extracting tool. The cerebrospinal fluid extracting tool comprises a drainage needle, a clamping assembly convenient for medical personnel to apply forcefor acupuncturing, and an intracranial pressure measuring assembly for measuring intracranial pressure of a patient, wherein the clamping assembly comprises two clamping plates which are hinged together and two elastic cushions each of which is arranged on the outer side of the corresponding clamping plate, is jointed with the outer wall of the drainage needle to increase friction; and a finger extruding block is arranged outside each clamping plate. According to the cerebrospinal fluid extracting tool disclosed by the invention, through cooperation of the two clamping plates in hinging connection, the finger extruding blocks and the elastic cushions for usage, compared with a conventional cerebrospinal fluid extracting manner, the technical scheme of the cerebrospinal fluid extracting tool disclosed by the invention can effectively solve the problem that the needle diameter of the drainage needle is small, so that medical personnel inconveniently applies force; and the working efficiency of the work of cerebrospinal fluid extracting is effectively improved, so that the iatrogenic infection caused by that the hand of the medical personnel is in direct contact with the drainage needle is further avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cerebrospinal fluid extraction tool. Background technique [0002] Cerebrospinal fluid is a colorless and transparent liquid that exists in the ventricle and subarachnoid space. Cerebrospinal fluid is continuously produced and absorbed back into the veins. It plays the role of lymph in the central nervous system. It supplies certain nutrients to brain cells, removes metabolites from brain tissue, regulates the acid-base balance of the central nervous system, and buffers Pressure on the brain and spinal cord, has a protective and supportive effect on the brain and spinal cord. [0003] In the medical field, cerebrospinal fluid contains certain cells and chemical components. Under pathological conditions, substances separated by the blood-brain barrier can enter the cerebrospinal fluid, causing changes in its composition. Cerebrospinal fluid tests can understand these ch...
