Description
Technical field
The present invention relates to medical instruments field, and in particular to a kind of automatic draw-out device of human bone marrow.
Background technology
With the continuous development of present social economy, the living standard of people is also constantly being lifted, for quality of the life
Pursue also more and more higher.
Hematopoietic tissue in human body, in the pulp cavity and all cancellous bones of long bone.The marrow of adult is divided to two kinds：Red bone
Marrow and yellow marrow.Red marrow can manufacture red blood cell, blood platelet and various leucocytes.Marrow not still hematopoietic tissue, it is still weighed
That wants is immune.
The usual paper bag of needle tubing is punctured now containing function is punctured, and needle tubing is used into solid needle tube lining core mostly, whole needle tubing is only
In the presence of a single-chamber passage, required tissue can only be extracted from patient's body by the way of extracting during drainage.
This operating method is relatively simple, and in this needle tubing easily bone marrow extraction, only by needle tip bit extraction marrow, takes out
Some is taken individually to organize excessively, just easily to cause certain somatic damage.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of automatic draw-out device of human bone marrow, solves existing skill
The absorption mode of single-chamber passage easily brings the technical problem of sore spot to patient among art.
To realize object above, the present invention is achieved by the following technical programs：
A kind of automatic draw-out device of human bone marrow, including injection tube body, block, push rod, injection needle, fixed connecting base,
Draw-out device, the injection tube body bottom portion are connected with injection needle by fixed connecting base, and the injection tube bodies top passes through
Piston is connected to push rod bottom, block is connected with the top of the push rod, the injection needle is divided into outer needle tubing and inner needle tube, described outer
It is cased with inner needle tube in needle tubing, annular is provided with the sucker of strip on the inner needle tube wall, and liquid is provided with the injection tube body
Body controls check valve, and the side of the injection tube body is provided with voltage indicating device.
Further, the injection tube body upper part being arranged on where the liquid control check valve of the voltage indicating device.
Further, some groups are provided with the voltage indicating device and takes out pressure hole.
Further, the block upper top is the arcuate structure to cave inward.
Further, the injection tube body side is provided with scale marker.
Further, the width of the sucker is 0.1-0.2mm, and is evenly distributed on inner needle tube wall.
Further, the outer needle tubing and inner needle tube bottom are provided with the inclined-plane with the horizontal 45 degree of angles.
Further, 0.1-0.2mm gaps are reserved between the inner needle tube and the outer needle tubing.
The invention provides a kind of automatic draw-out device of human bone marrow, passes through outer needle tubing and the inner needle tube phase designed on device
Mutually it is used cooperatively, the gap of marrow to be extracted along outer needle tubing and inner needle tube is flowed into the sucker of inner needle tube, is taking out press fitting
Under the drive put, the extraction operation of outer needle tubing and inner needle tube to marrow is realized.Whole device is reasonable in design, simple operation, can be
It is used more widely in actual use.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, come for those of ordinary skill in the art
Say, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
