Abstract

The invention relates to a novel lumbar puncture bag provided with a pressure sensor, and belongs to the technical field of medical instruments. The lumbar puncture needle insertion position is as accurate as possible through magnitude and change of resistance and visualization of the needle insertion depth in the needle insertion process, complications caused by too deep puncture in an existing lumbar puncture technology can be reduced, and the accuracy and safety of lumbar puncture are improved. The lumbar puncture bag provided with the pressure sensor is simple and convenient to operate, and a pressure pipe and a test tube are assembled on lumbar puncture equipment in advance, so that components are prevented from being taken in the process, and the lumbar puncture process is simpler and more convenient. Meanwhile, five replaceable parts needing to be disinfected are arranged in a storage bag, and replacement selection is provided; and a puncture needle with the length of 8 cm is suitable for adults and children, so that the universality of the equipment is enhanced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a novel waist puncture bag. Background technique [0002] Lumbar puncture is one of the commonly used clinical examination methods in neurology. It can be used for examination and treatment of various diseases, and has high clinical application value. [0003] When performing a lumbar puncture, the patient lies on his side on the bed, with his head bent toward his chest, his hands tucking his knees close to his chest, and his lower back arched as far back as possible to increase the width of the lumbar intervertebral space. Select the third and fourth lumbar intervertebral space as the puncture point, and insert the needle vertically along the main intervertebral space, 4-6 cm for adults and 2-3 cm for children. A sudden loss of resistance is felt, indicating that the needle has entered the meningeal cavity. [0004] The strain gauge of the pressure sensor measures ...
