Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a lumbar puncture needle assembly with positioning and color developing functions.
Background
Lumbar puncture is an indispensable examination and treatment method in operations such as diagnosis of neurologic diseases, spinal anesthesia, spinal administration, spinal radiography, cerebrospinal fluid drainage, and the like. The lumbar puncture needle used in most China at present is a traditional "quinine" lumbar puncture needle, and consists of a stainless steel needle core, a stainless steel lumbar puncture needle and a needle seat, and has the following defects: 1. the anti-bacterial agent is made of stainless steel, and in the process of repeated use, cross infection is likely to be caused by incomplete disinfection; 2. because the needle body is slim, the advancing direction of the needle body is difficult to control when the lumbar vertebra is advanced, the difficulty of lumbar vertebra operation is increased, and unnecessary pain is caused to patients; 3. when the "quinine" lumbar puncture needle is used, the cerebrospinal fluid flow cannot be directly observed in the operation drainage process, so that the needle core is required to be completely extracted, the situation that cerebral spinal fluid is sprayed outwards occurs to a patient with high cranium pressure, cerebral hernia is easy to occur, and a series of sequelae such as postoperative low cranium pressure, headache and the like can be brought to the patient with high cranium pressure due to excessive cerebrospinal fluid outflow; 4. It is made of stainless steel and is expensive.
