Problems solved by technology

[0003] The existing lumbar needles do not have a fixing device for auxiliary fixation in the actual use process, resulting in the needle tube being easily displaced during the extraction of cerebrospinal fluid, which will not only affect the collection of cerebrospinal fluid, but also cause injury to the patient, and the existing collection Manual collection of cerebrospinal fluid is difficult to perform quantitative collection

Abstract

The invention discloses a lumbar vertebra needle with integrated integrated quantitative collection. The lumbar vertebra needle with integrated quantitative collection comprises a lumbar vertebra needle body, the lumbar vertebra needle body is composed of a puncture needle and a liquid suction box, the puncture needle is sleeved with an anti-deviation block, a needle core and a liquid suction pipeare inserted into the puncture needle, the puncture needle, the anti-deviation block and the needle core are provided with a same adsorption mechanism, the needle core and the puncture needle are provided with a same limiting assembly, and the liquid suction box and the liquid suction pipe are provided with a same quantitative liquid suction mechanism. According to the present invention, throughthe arrangement of the adsorption mechanism, the quantitative liquid suction mechanism and the limiting assembly, when the depth of the puncture needle inserted into the body of a patient is adjusted,the whole lumbar vertebra needle can be firmly adsorbed, the collection stability is improved, and cerebrospinal fluid can be quantitatively and accurately collected.

Description

technical field [0001] The invention relates to the technical field of cerebrospinal fluid collection of medical equipment, in particular to an integrated lumbar spine needle for quantitative collection. Background technique [0002] Lumbar puncture is an important diagnostic and therapeutic operation in neurosurgery clinical work. It can be used to diagnose various inflammatory diseases of the central nervous system, vascular diseases, spinal cord lesions, suspected intracranial space-occupying lesions, and undiagnosed nervous system diseases. Diseases and pneumoencephalography and myelography, etc. It can also be used for draining and injecting drugs due to excessive pressure of cerebrospinal fluid to treat diseases of the central nervous system. [0003] The existing lumbar needles do not have a fixing device for auxiliary fixation in the actual use process, resulting in the needle tube being easily displaced during the extraction of cerebrospinal fluid, which will not o...
