Technical Field

[0001] The invention relates to the field of training mold devices, in particular to a lumbar puncture training mold. Background Art

[0002] Lumbar puncture is a commonly used clinical diagnostic procedure. It can be used to diagnose various inflammatory diseases of the central nervous system, vascular diseases, spinal cord lesions, suspected intracranial space-occupying lesions, undiagnosed neurological diseases, pneumoencephalography, myelography, etc. It is also used to drain (decompress) cerebrospinal fluid due to excessive pressure and inject drugs to treat central nervous system diseases.

[0003] The existing lumbar puncture practice mold generally uses a spinal simulation hose as a practice mold. Generally, the spinal simulation hose is fixed before lumbar puncture practice. Although during lumbar puncture, the patient generally needs to remain motionless to avoid the needle from being inserted into the wrong position or even causing secondary injury, it is unavoidable that the patient will cough, hiccup, etc., which may cause slight shaking of the body. The spinal simulation hose used for normal practice is fixed, which causes novices to be at a loss when encountering such body shaking during lumbar puncture. Therefore, a lumbar puncture practice mold is needed to adjust the activity state of the spinal simulation hose so that the practitioner can adapt to the situation when the patient shakes slightly.
