Abstract

The invention discloses a bone marrow fluid rapid and quantitative extraction device for the hematology department. The device comprises a sleeve rod, wherein the left side of the sleeve rod communicates with a liquid outlet pipe, and the left side of the liquid outlet pipe is in threaded connection with a threaded connector. The left side of the threaded connector communicates with a connecting hose, and the left side of the connecting hose communicates with a puncture needle. A driving frame is fixedly connected to the right side of the sleeve rod, and an electric telescopic rod is fixedly connected to the right side of an inner cavity of the driving frame. Through the sleeve rod, the puncture needle, the driving frame, screw rods, a driving disc, a transparent observation window, a rubber stop block, a moving rod, a piston, a screw block, a moving plate and the electric telescopic rod of the invention, the quantitative extraction function of the device can be achieved. The problemsthat an existing marrow fluid extraction device on the market does not have the quantitative extraction function, quantitative extraction cannot be achieved in the bone marrow extraction process in the using process, and the extraction amount is difficult to control for staffs, thereby not being beneficial to disease analysis and treatment are solved.

Description

technical field [0001] The invention relates to the technical field of bone marrow fluid extraction devices, in particular to a rapid and quantitative extraction device for bone marrow fluid used in hematology. Background technique [0002] Bone marrow exists in the cancellous cavity of bone and the marrow cavity of long bones. It is composed of various types of cells and reticular connective tissue. According to its structure, it is divided into red bone marrow and yellow bone marrow. It is a soft tissue rich in blood. [0003] In the course of orthopedic treatment, bone marrow extraction is required. The existing bone marrow fluid extraction devices on the market do not have the function of quantitative extraction. During the use of bone marrow extraction, it is difficult to control the amount of bone marrow extraction, which is not conducive to Disease analysis and treatment. Contents of the invention [0004] The purpose of the present invention is to provide a rapid ...
