Rapid quantitative bone marrow fluid extraction device for hematology department

Abstract

The invention belongs to the technical field of bone marrow fluid extraction devices, and particularly relates to a rapid quantitative bone marrow fluid extraction device for the hematology department. The device comprises a bone marrow puncture needle main body; the upper end of the bone marrow puncture needle main body is clamped and connected with a bidirectional jacket, and the upper end of the bidirectional jacket is clamped and connected with a fixed clamping sleeve for rapidly replacing a needle core; a suction needle used for extracting marrow fluid of a patient is arranged in the fixing clamping sleeve, and a rubber sleeve used for preventing the suction needle from sliding is arranged on the outer side of the suction needle in a sleeving mode. Through the bidirectional jacket arranged at the upper end of the bone marrow puncture needle main body, the bone marrow puncture needle main body is more stable during puncturing, and the working efficiency is improved; the replacement speed of the needle core is increased through the fixed clamping sleeve connected to the upper end of the bone marrow puncture needle body in a clamped mode; through the rubber sleeve arranged at the upper end of the suction needle in a sleeving mode, the needle core is stable and not prone to sliding, and suction work is smoother; and through the screw arranged in the transparent graduated needle cylinder, extraction is quantitative, and waste is not prone to occurring.

Description

technical field [0001] The invention belongs to the technical field of bone marrow fluid extraction devices, and in particular relates to a rapid and quantitative extraction device for bone marrow fluid used in hematology. Background technique [0002] The fluid in bone marrow, also known as bone marrow, belongs to connective tissue and is located in many bones of the body. 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, which are soft and rich in blood. organize. Red bone marrow can produce red blood cells, platelets and various white blood cells. It is a human hematopoietic organ and immune organ. The main component of yellow bone marrow is fat and has no hematopoietic function. red bone marrow. [0003] The original bone marrow fluid extraction device often cannot control the amount of bone marrow fluid extracted during the extraction operation, resulting in ...

AI Technical Summary

Problems solved by technology

[0003] The original bone marrow fluid extraction device often cannot control the amount of bone marrow fluid extracted during the extraction operation, resulting in unnecessary losses. It is more complicated to replace the needle core when extracting bone marrow fluid, and the replacement cannot be completed quickly. The connection between the needle core and the extraction device It is not stable enough, which affects the extraction efficiency, and the needle core is easy to slide during the working process, which affects the extraction work
