The utility model relates to the technical field of medical equipment, especially a quantitative extraction device for bone marrow fluid used in hematology. The utility model includes a needle barrel and a bone piercing needle. Two spring protrusions are symmetrically arranged on the inner wall of the barrel, and the rubber bowl is matched with the piston head. There is a piston in the syringe, a conical piston head at the front end of the piston, and two symmetrical pits on the bottom edge of the piston head. The spring protrusions are properly matched with the pits; the outer wall of the bone puncture needle near the needle point is provided with a plurality of liquid-absorbing through holes. The utility model has reasonable structural design, convenient use, wide extraction range, avoids the problem of bone marrow fluid sticking to the piston, prevents excessive extraction, is beneficial to the diagnosis of blood diseases, relieves the pain of patients, and reduces the work intensity of medical staff.
Description
Technical field
This utility model relates to technical field of medical instruments, especially the quantitative draw-out device of bone marrow fluid for blood internal medicine.
Background technology
At present, in blood internal medicine clinic diagnosis, diagnosis to hematologic disease usually needs bone marrow extraction liquid to test, and during bone marrow extraction, is generally with common syringe, the needle point place of its syringe needle is the inclined-plane opening, this syringe needle is when bone marrow extraction, and bone marrow is drawn into puncture needle from the inclined-plane opening, and the scope of the bone marrow extracted only limits to the inclined-plane opening part, the scope extracted is too little, is unfavorable for the diagnosis of disease.In addition, in the process of bone marrow extraction liquid, the bad assurance of extraction dynamics, tend to cause the bone marrow fluid dilution if the bone marrow fluid extracted is greater than 0.2ml, thereby affect the judgement of nucleated cell hypertrophy degree, cell counting and classification etc.
The utility model content
The purpose of this utility model is to provide the quantitative draw-out device of bone marrow fluid for blood internal medicine in order to overcome above-mentioned technical disadvantages.
The technical scheme that this utility model technical solution problem adopts is: the quantitative draw-out device of bone marrow fluid for blood internal medicine, comprise syringe and medullo-puncture needle, described syringe connects medullo-puncture needle, the syringe interior forward end is provided with rubber bowl, is arranged with two spring projections on the syringe inwall, is provided with piston in syringe, piston nose is provided with cone shape piston head, the piston head root edge is arranged with two pits, and rubber bowl is fitted coupling mutually with piston head, and the spring projection is fitted coupling mutually with pit.
Offer a plurality of imbibition through holes on the outer wall of described medullo-puncture needle near the needle point position.
Know-why of the present utility model is by presetting the position of spring projection, and when spring projection and pit clamping, the spatial volume between piston head and rubber bowl is fixed, to adapt to the bone marrow fluid aspiration under different patients, different situations.
The beneficial effect that this utility model has is: this utility model reasonable in design, and easy to use, the extraction scope is wide, avoid the problem of bone marrow fluid and piston adhesion, prevented overdraft, be conducive to the diagnosis of hematologic disease, alleviate patient's misery, reduced medical personnel's working strength.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with 1 pair of this utility model of accompanying drawing, be described below.
As shown in Figure 1, this utility model comprises syringe 1 and medullo-puncture needle 2, described syringe 1 connects medullo-puncture needle 2, syringe 1 interior forward end is provided with rubber bowl 4, is arranged with two spring projections 6 on syringe 1 inwall, is provided with piston 3 in syringe 1, piston 3 front ends are provided with cone shape piston head 7, piston head 7 root edges are arranged with two pits 5, and rubber bowl 4 is fitted coupling mutually with piston head 7, and spring projection 6 is fitted coupling mutually with pit 5; Offer a plurality of imbibition through holes 8 on the outer wall of described medullo-puncture needle 2 near the needle point position.
In the present embodiment, determine the position of spring projection 6, make when spring projection 6 and pit 5 clamping, the spatial volume between piston head 7 and rubber bowl 4 is 0.2ml, to prevent bone marrow fluid, crosses suction phenomenon.
