Abstract

A bone marrow puncture device for hematology, comprising a support mechanism detachably arranged on an examination bed and a puncture mechanism arranged on the support mechanism, the puncture mechanism includes a needle body, the needle body includes a movable outer catheter, and the outer catheter communicates with bone marrow output An inner catheter is installed inside the outer catheter, and the outer diameter of the inner catheter is smaller than the inner diameter of the outer catheter. One end of the inner catheter is connected with an anesthetic input tube, and the other end of the inner catheter extends out of the outer catheter and is fixedly connected with a conical needle tip. The diameter of the big end is equal to the outer diameter of the outer catheter. An outlet connected to the inner catheter is provided on the side wall of the needle tip. A soft blocking sheet is arranged on the outside of the outlet. The lower part of the soft blocking sheet is fixedly connected with the needle tip. The invention provides a bone marrow puncture device for hematology, which has higher positioning accuracy and does not contaminate bone marrow fluid with anesthetics.

Description

technical field [0001] The invention relates to the technical field of bone marrow puncture, in particular to a bone marrow puncture device for hematology. Background technique [0002] Bone marrow aspiration is a common diagnostic technique for collecting bone marrow fluid. Clinically, bone marrow aspiration is also commonly used for blood cell morphology examination, and can also be used for hematopoietic stem cell collection, culture, cytogenetic analysis, and pathogenic biology inspection. The collection tools used to collect bone marrow fluid are usually based on bone puncture needles. The commonly used bone puncture needles are not oriented accurately during puncture. The bone marrow cavity is pierced out of the bone marrow cavity; at the same time, the puncture depth cannot be precisely controlled. [0003] In addition, local anesthesia is required before bone marrow puncture. The existing technology mainly adopts two methods. One is to perform local anesthesia and b...
