A device for extracting cerebrospinal fluid from patients with hematological tumors

Abstract

The invention relates to the technical field of cerebrospinal fluid extraction for patients with hematological tumors, and discloses a cerebrospinal fluid extraction device for patients with hematological tumors, including a strap. The surface of the strap is movably connected with a flexible belt, and the surface of the flexible belt is movably connected with a positioning block. One end of the back strap is movably connected with a clamping box through a connecting rod, the inside of the clamping box is movably connected with a clamp ring, the inside of the clamp ring is fixedly connected with an air bag, and the surface of the air bag is fixedly connected with a ventilation pipe. Move the exhaust plate to the placement table. This step is the rough adjustment of the perforation positioning. The bellows are squeezed to generate gas. Because the placement table is only fixedly connected with the fourth last positioning block, only the gas generated by the bellows connected to it It will enter the inside of the exhaust plate through the telescopic rod, and the gas will flow to the chute, push the push rod out, and push the placement table to move. In addition, the perforation positioning is finely adjusted, and the two-step adjustment is combined to achieve the effect of improving the precise puncture positioning.

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,...

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 deviation in the puncture site, it will bring unexpected dangers to the patient; In order to detect whether the subarachnoid space of the patient is blocked, the carotid artery of the patient can not only be controlled by manual pressure, but also easily make the patient emotionally tense, resulting in increased intracranial pressure in the brain, which is not conducive to the operation. The cerebrospinal fluid extraction device came into being
