The collective effect of push plate gravity and compressed spring again, counterweight push plate start to push push rod along the length direction of syringe, and push rod is logical
It crosses piston the marrow blood in syringe cylinder body is slowly injected into filter tunnel, after the strainer filtering in filter tunnel, bone
Marrow blood flows into helix tube, then enters drainage tube through helix tube, then enters blood taking bag by drainage tube again, completes marrow blood
It is collected by filtration, wherein it is free can to slow down marrow blood in the speed that marrow blood flows downward, with traditional technology for the setting of helix tube
The mode of falling bodies is compared, and largely Blood cells in bone marrow is protected to be not damaged;Air valve is set on blood taking bag, it is convenient to collect
The gas in blood taking bag is discharged when marrow blood, blood taking bag is connected on a certain fixing piece by link;
The bung of the utility model is mounted on the top of filter vat by notch, and such mounting means is quick, uses
Convenient, secondly filter tunnel is also to be detachably connected in filter vat, can be convenient replacement filter tunnel in this way;Secondly, this reality
The speed of syringe injection can be changed with this with novel by adjusting the tilt angle of mounting plate and the elastic force of compressed spring
Degree, i.e., rotate mounting plate around pin shaft, until positioning bolt is screwed after proper angle, so that the inner end of positioning bolt and pin shaft top
Press-fit, to change the tilt angle of mounting plate, since mounting plate tilt angle changes, according to weight force resolution, counterweight is pushed away
Plate follows change to the thrust size of the push handle of syringe, so that syringe injection speed changes;In addition adjusting nut is screwed, is made
The elastic force for obtaining compressed spring changes, to change connecting rod to the pulling force of counterweight push plate, changes the injection speed of syringe with this;
In conclusion the structure design of the utility model is reasonable, Blood cells in bone marrow is protected by the way that helix tube is arranged, by setting
Four groups of syringe mounting assemblies are set, to keep slowly injecting, to greatly reduce the workload of medical staff.
