Problems solved by technology

[0004] Above, the weak point of the prior art is that, because the collection needle can only extract the limited bone marrow near the needle, the amount of extraction is too small, so that the number of bone marrow punctures is too much

Abstract

The invention discloses a bone marrow collecting device. The bone marrow collecting device comprises a sleeve pipe and a needle core sleeved in the sleeve pipe, wherein an input channel used for inputting an impact liquid and an output channel used for extracting a bone marrow mixture are arranged in the needle core. The bone marrow collecting device further comprises an impact system and a collecting system, wherein the impact system comprises a storage cavity, an impact pump and an impact pipeline, wherein the impact pipeline communicates with the input channel; the impact pump is used for outputting the impact liquid in the storage cavity into the input channel; and the collecting system comprises a collecting cavity which communicates with the output channel through a pipeline. According to the bone marrow collecting device provided by the invention, a bone marrow cavity is impacted through a high-speed liquid flow of the impact system, so more bone marrow in a larger range is extracted, and the number of times of puncture is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a bone marrow harvesting device. Background technique [0002] As we all know, bone marrow collection is the main therapy for the clinical treatment of leukemia, and it is also commonly used in cytogenetic analysis and etiological examination. Among them, when used to treat leukemia, it is necessary to extract a large amount of bone marrow, that is, hematopoietic stem cells. For inspection and analysis, only a small amount needs to be extracted. Since the bone marrow that can be obtained from each bone marrow puncture point is relatively limited, multiple punctures at multiple points are required to obtain a sufficient amount of hematopoietic stem cells during leukemia treatment. [0003] In the prior art, there are two reasons why each puncture point can only obtain limited hematopoietic stem cells. One is that the bone marrow capacity of each location is limited, which is an objective fact ...
