Problems solved by technology

[0003] When performing puncture extraction, it is necessary to puncture the same part to extract bone marrow. Anesthesia puncture and marrow extraction puncture are performed separately, and the number of punctures increases, which increases the pain of the patient. In addition, during the puncture extraction process, the patient is prone to nervousness and movement, which affects the effect of bone marrow extraction. , it is impossible to protect the puncture position, so in view of this, the existing structure and defects are studied and improved, and a bone marrow puncture extraction device for leukemia patients in the Department of Hematology is provided, in order to achieve more practical purposes

Abstract

The invention provides a bone marrow puncture extraction device for leukemia patients in hematology department, a piston plate is slidably mounted in a bone marrow extraction cylinder and an anesthetic cylinder, connecting pipes are fixedly connected to the bottom ends of the bone marrow extraction cylinder and the anesthetic cylinder, and puncture needles are fixedly connected to the tail ends ofthe adjacent connecting pipes; a first valve and a second valve corresponding to the bone marrow extraction cylinder and the anesthetic cylinder are arranged on the left side and the right side of the puncture needle respectively, and the puncture needle is fixedly mounted at the bottom of a partition seat. When a swing rod rotates to the left side, after the swing rod presses the supporting rod,the right end of the supporting rod drives the piston plate in the marrow extraction cylinder to jack up, meanwhile, a movable frame extrudes the pressing rod to move downwards, the pressing rod drives the bottom rod to move downwards through the inclined face of the surface of a stress rod, the second valve is closed, and therefore marrow extraction is conducted. Therefore, the effects of anesthesia and bone marrow extraction can be achieved only by puncturing a patient once, and the pain of the patient is effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bone marrow puncture extraction device for leukemia patients in the Department of Hematology. Background technique [0002] Hematology is a branch of internal medicine that mainly treats the problems of the hematopoietic system. For the treatment of leukemia patients in the Department of Hematology, bone marrow puncture is often required. Bone marrow puncture is to extract bone marrow with a conventional bone marrow puncture needle. When extracting bone marrow, you need to use an injection needle first. Anesthetic puncture is performed at the puncture point, and then a bone marrow puncture needle is used to puncture and extract bone marrow at the same site. [0003] When performing puncture extraction, it is necessary to puncture the same part to extract bone marrow. Anesthesia puncture and marrow extraction puncture are performed separately, and the number ...
