Abstract

The invention relates to a bone marrow aspiration device for the hematology department. The device comprises a support mechanism detachably arranged on an examination bed and a puncture mechanism arranged on the support mechanism, the puncture mechanism comprises a needle body which comprises a movably arranged outer catheter, the outer catheter is communicated with a bone marrow output tube, an inner catheter is movably arranged in the outer catheter, the outer diameter of the inner catheter is smaller than the inner diameter of the outer catheter, one end of the inner catheter is communicated with an anesthetic input tube, the other end of the inner catheter stretches out of the outer catheter and then is fixedly connected with a conical needle tip, the diameter of the large end of the needle tip is equal to the outer diameter of the outer catheter, the side wall of the needle tip is provided with an outlet communicated with the inner catheter, a soft blocking piece is arranged on the outer side of the outlet, and the lower portion of the soft blocking piece is fixedly connected with the needle tip. According to the bone marrow aspiration device for the hematology department, thepositioning accuracy is higher, and the phenomenon that anesthetic contaminates a bone marrow fluid cannot occur.

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...
