Specimen sampler for neurology department

Abstract

The invention discloses a neurology specimen sampler which comprises a sampling barrel, a one-way valve is mounted on the left side of the sampling barrel, a hose is fixedly connected to the middle of the left side of the sampling barrel, a protection assembly is arranged at the left end of the hose, a puncture assembly is arranged in the protection assembly, and the puncture assembly is communicated with the hose. A piston ring is slidably connected into the sampling barrel, an energy storage assembly is arranged between the piston ring and the inner wall of the right side of the sampling barrel, a sliding rod is fixedly connected to the middle of the right side of the piston ring, and the right end of the sliding rod penetrates through the right side of the sampling barrel; in the moving process of the needle head, the conical thorn can be driven to move leftwards, and the liquid inlet hole is exposed for sampling, so that the liquid inlet hole in the needle head is not easily attached to skin cells during puncturing, a sample is prevented from being polluted, a detection result is more accurate, a worker does not need to perform drawing operation for a long time, and the needle head is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of neurology, in particular to a neurology specimen sampler. Background technique [0002] Neurology is a secondary discipline about neurology and does not belong to the concept of internal medicine. It mainly treats cerebrovascular diseases, migraine, brain inflammatory diseases, myelitis, epilepsy, dementia, metabolic diseases and genetic predisposition diseases, trigeminal neuralgia, sciatic neuropathy, peripheral neuropathy and myasthenia gravis. In the course of treatment and nursing of neurological diseases, cerebrospinal fluid pressure measurement and specimen sampling are often performed on patients. [0003] Most of the existing specimen samplers for neurology use a combination of a single needle and a sampling cylinder. The liquid inlet hole on the needle is easily attached to the skin cells and moves into the spinal fluid during puncture. The pulling operation is easy to cause the fatigue of the...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing neurology specimen samplers use a combination of a single needle and a sampling cylinder. The liquid inlet hole on the needle is easy to adhere to the skin cells and move into the spinal fluid during puncture, so that the extracted samples are polluted, and the long-term sampling Pulling operation is easy to cause the fatigue of the staff. When sampling, the sampling volume is usually manually judged, which may easily cause too little or too much sampling volume, and the use effect is poor.
