Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1：
The harvester of marrow in joint replacement, including：Three-way pipe 1 sets three-way cock 2 on three-way pipe 1, and one connects
Mouth connects blowing device 3 by active joint 7, and an interface connects suction device for storing liquid 4 by active joint 7, another connects
Conduit 5 on mouth is set, strainer 6 is set in conduit 5, the port of conduit 5 passes through active joint 7 and connects lengthened hose 8.
Three-way cock 2 is T shape rotary types, when T shapes side corresponds to the interface of three-way pipe 1, interface conducting.Blowing device 3 by
Air bag 31 and connecting tube composition, air bag 31 are corrugated, spring 32 of the inside setting along 31 longitudinal direction of air bag.Aspirate device for storing liquid 4
For syringe type, inside connection suction handle 41, external connection gripping handle 42, suction handle 41 is linear surface shape, is held
Handle 42 is frame-like, and suction handle 41 is in 42 inside straight reciprocating motion of gripping handle.Conduit 5 is protruding, inside setting
Double-layer leaching net 6.Active joint 7 is cylinder, and inside is coarse circular groove.
Blowing device 3 is made of a hollow cylinder body end and threaded head end, the 31 fixed spring 32 in center of air bag.
When 5 head end of conduit of imbibition is blocked by bone slag, 31 tail portion of air bag of jet is pressed, then bone slag in conduit 5 can be sprayed.Lead to again
It crosses spring 32 to spring back, air bag 31 resiles.
Three-way cock 2 can adjust working condition.When adjustment three-way cock 2 to conduit 5 is communicated with suction device for storing liquid 4,
It can carry out the suction of bone marrow fluid；When adjustment three-way cock 2 is communicated to conduit 5 with blowing device 3, bone slag in pipette can be facilitated
Discharge.
The lever that suction handle 41 and gripping handle 42 design can allow user effectively to hold suction device for storing liquid 4,
It is this to design the output for being more advantageous to suction force, make drawing liquid stronger.Skidding when handle design can more prevent from capturing in art.
Conduit 5 is a plastic rigid pipe, for drawing intracapsular bone marrow fluid.It is connected to three-way pipe one end.In conduit 5
Equipped with strainer 6, for filtering marrow, prevent the impurity such as bone slag from entering conduit 5.The other end of conduit 5 can connect lengthened hose 8, use
Bone marrow fluid in the long ossis of absorption.
Operation principle and use process：
This bone marrow collection device is divided to two kinds of working conditions：First, marrow aspiration working condition；Second is that imbibition tube head is gone out in exhaust
Hold bone slag working condition.
1. marrow aspiration：When needing to draw marrow, the right hand holds suction handle 41 and gripping handle 42, by three-way cock
2 adjust to conduit 5 and suction 4 communicating state of device for storing liquid.Hold suction handle 41 and gripping handle 42, marrow aspiration liquid.Such as
Liquid in ossis is drawn, then installs lengthened hose 8 additional in head end.
2. pipette head end bone slag is gone out in exhaust：When bone slag 5 head end of obstruction conduit, three-way cock 2 is adjusted to conduit 5
With 3 communicating state of blowing device, 3 tail portion of pressing blowing device can then spray bone slag in conduit 5.
After acquisition, suction device for storing liquid 4 is backed out.The bone marrow neoplasms aspirated in device for storing liquid 4 to dedicated storage are held
In device.
