Diversion trench is opened up on syringe inner wall, the diversion trench extends to the outlet end of syringe；The inlet of the perfusion tube is pierced by syringe
Outside, and anesthesia outfit is connected.
In a preferred embodiment, it is spaced on the perfusion tube and uniformly opens up four fluid holes, five fluid holes
Correspondence opens up four diversion trenches on the syringe inner wall of corresponding position.
In a preferred embodiment, the anesthesia outfit includes anesthesia syringe, and setting is lived in the anesthesia syringe
It fills in, push rod is installed on piston, tonic mouth is offered in the anesthesia barrel sidewall, and valve is set on the tonic mouth.
In a preferred embodiment, the Bone marrow collection device includes surge drum, and setting is lived in the surge drum
Stick harness installs pumping rod on piston boit；And the piston boit and surge drum are tightly connected.
In a preferred embodiment, the block that setting can stop pumping rod to slip on the surge drum inner wall.
In a preferred embodiment, graduation mark is set on the collection drum outer wall.
The blood internal medicine bone marrow aspiration draw-out device of the utility model is compared with existing puncture draw-out device, beneficial to effect
Fruit is that it is possible to the existing anesthetic puncture of effective solution and marrow puncture is taken to need the problem of separately carrying out, and largely mitigates
The pain of patient, simplifies surgical procedure；And on this basis, anesthesia liquid is uniformly transported to puncture by the utility model
Around point, keep anaesthetic effect more preferable, not will cause that local anaesthetic effect is bad, increases the problem of the pain of patient.In addition, this
Utility model whole design is reasonable, of simple structure and strong practicability.

Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described,
Obviously, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.It is practical based on this
Embodiment in novel, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, is fallen within the protection scope of the utility model.
According to Fig. 1-4, illustrate the utility model preferred embodiment.
As shown in Figs 1-4, the blood internal medicine bone marrow aspiration draw-out device of the utility model, the syringe including hollow cylinder
1, puncture needle 2 is arranged in the cavity of above-mentioned syringe 1, Bone marrow collection device is arranged in one end of puncture needle 2, in above-mentioned syringe 1
An annular fixing groove is circumferentially opened up on wall, fixes perfusion tube 3 in above-mentioned fixing groove, since the barrel of syringe 1 has certain thickness
Degree, opens up fixing groove on its inner wall, can be connected to perfusion tube 3 in slot fixed；Liquid is uniformly opened up out on above-mentioned perfusion tube 3
