Problems solved by technology

[0004] Lumbar puncture has undergone many clinical trials, and its technology is relatively mature. However, due to the complex structure of the human body, there is no corresponding equipment for lumbar puncture to assist medical personnel. Therefore, it requires medical personnel with rich clinical experience to implement it. This kind of operation, but only relying on experience to operate, must have certain risks. If there is a deviat

Abstract

The invention relates to the technical field of cerebrospinal fluid extraction for hematologic tumor patients, and discloses a cerebrospinal fluid extraction device for hematologic tumor patients. Thedevice comprises a strap, a flexible strap is movably connected to the surface of the strap, a positioning block is movably connected to the surface of the flexible strap, a clamping box is movably connected to the end, away from the strap, of the flexible strap through a connecting rod, a clamping ring is movably connected to the interior of the clamping box, an air bag is fixedly connected to the interior of the clamping ring, and a vent pipe is fixedly connected to the surface of the air bag. The step of moving an exhaust plate to a placing table is perforation positioning coarse adjustment, and a corrugated pipe is extruded to generate gas. As the placing table is only fixedly connected to the fourth from last positioning block, only the gas generated by the corrugated pipe connectedto the placing table can enter the exhaust plate through a telescopic rod. The gas flows to a chute to push out a push rod to push the placing table to move. In addition, perforation positioning fineadjustment and two-step adjustment are combined, so that the effect of improving puncture positioning accuracy is achieved.

Description

technical field [0001] The invention relates to the technical field of cerebrospinal fluid extraction for hematological tumor patients, in particular to a cerebrospinal fluid extraction device for hematological tumor patients. Background technique [0002] The common types of hematological tumors mainly include various types of leukemia, multiple myeloma, and malignant lymphoma. Patients with hematological tumors often need to aspirate cerebrospinal fluid to detect whether there are lesions in the brain. [0003] Cerebrospinal fluid is: Cerebrospinal fluid is a colorless and transparent liquid that exists in the ventricle and subarachnoid space. The commonly used method of suction is lumbar puncture. Lumbar puncture usually requires the patient to bend over and lie on the side, and the fluid is taken from the lumbar 2 to the sacrum. 1 (mainly lumbar 3-4) intervertebral space puncture, the puncture depth is about 4-6cm for adults (about 3-4cm for children), within this range,...
