Problems solved by technology

[0003] 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 volume of bone marrow extracted is not precisely controlled, and the puncture depth cannot be precisely controlled

Abstract

The invention discloses a bone marrow aspiration needle of hematology department. The bone marrow aspiration needle of hematology department comprises an aspiration needle tube, wherein the middle part of the aspiration needle tube is connected with a rotary body and a limiting ring through threads; an anti-skid rubber ring is sheathed on the surface of the rotary body, and the bottom part of the rotary body is connected with a fixer through a bearing; the end part of the fixer is connected with an absorbing body; the bottom part of the aspiration needle tube is connected with a needle head; a thread ring is arranged on the surface of the lower part of the aspiration needle tube; a plurality of needle holes are formed in the thread ring, and are communicated with an inner cavity of the aspiration needle tube; the surface of the aspiration needle tube is provided with scales; the side of the upper part of the aspiration needle tube is provided with a liquid storage groove; a negative pressure air bag is arranged at the top part of the liquid storage groove; a scale needle is penetrated into the side of the liquid storage groove, and a handle is sheathed at the top part of the aspiration needle tube. The bone marrow aspiration needle of hematology department has the advantages that the operation is simple, the workload of medical staff is decreased, the bone marrow is conveniently aspirated, the pain of a patient is reduced, the volume of bone marrow aspiration is accurate, and the aspiration depth can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hematology bone marrow puncture needle. 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. [0003] 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 volume of bone marrow extracted is not precisely controlled, and the puncture depth cannot be precisely controlled. Contents of the invention [0004] The purpose of the present invention is to provide a hematology b...
