Description
【Technical field】
The invention belongs to technical field of medical instruments.A kind of more particularly it relates to malleation liquid capsule self-sealing blood vessel
Interior remaining needle.
【Background technology】
The reason for blood vessel remaining needle plugging is the clotting factor such as blood platelet in blood when blood reflux enters in catheter lumen
In low flow velocity conduit intravascular coagulation, thrombus is formed and plugging.In order to ensure that conduit can be reused, it is necessary to prevented using tube sealing technology
Plugging, " tube sealing " have become a specific term in medical treatment and nursing.
At present, " tube sealing " in standard method is to inject physiological saline or heparin in sealing liquid in conduit " tube sealing ", this
" tube sealing " is to allow physiological saline or other tube-sealing solutions to occupy conduit cavity space as working solution matter, makes blood and its hemostatic composition
It can not enter in conduit；Secondly, physiological saline or other tube-sealing solutions in conduit dilute these blood coagulation substances, so as to can also prolong
Slow setting blood, form thrombus.
But human vein blood pressure fluctuates with breathing and heartbeat, tube-sealing solution is gradually lost in after transfusion stops, " just
The malleation of press seal pipe " disappears quickly, has blood reflux to enter in conduit at once, or even be extended to needle stand and farther woven hose
In, these blood coagulation substances can form microthrombus, and in addition to obstruction conduit influences transfusion, when infusing next time, these microthrombus are rushed
Enter blood circulation, block pulmonary capillaries, form Granuloma in lung and alveolar infarct.
Such issues that solution, best bet was that by opening in catheter tip in addition to frequently rinsing with tube sealing
Closing conduit at mouthful, or reduction are more near better from catheter opening towards vasotropic inlying catheter dead space, plugging device.
Therefore, these technological deficiencies be present for prior art, the present inventor is completed finally by lot of experiments
The present invention.
【The content of the invention】
[technical problems to be solved]
It is an object of the invention to provide a kind of intravascular remaining needle of malleation liquid capsule self-sealing.
[technical scheme]
The present invention is achieved through the following technical solutions.
The present invention relates to a kind of intravascular remaining needle of malleation liquid capsule self-sealing, it mainly by main element A, part I B with
Part II C are formed；Wherein main element A with recessed female Luer needle stand 1, inlying catheter 2 and infusion channel 3 by forming；With recessed
The end of female Luer needle stand 1 is inlying catheter 2, and inlying catheter 2 with the recessed inner chamber of female Luer needle stand 1 with forming infusion channel 3；
Part I B are by draw point core 4 with being formed by connecting with convex female Luer steel needle core handle 5；
Part II C are by as received basis liquid capsule 6, convex female Luer as received basis liquid capsule cap 7, inside and outside liquid capsule communicating pipe 8 and outer liquid capsule
9 are connected in sequence；Convex female Luer as received basis liquid capsule cap 7 is in the connection of as received basis liquid capsule 6 and inside and outside liquid capsule communicating pipe 8
Place；
In use, part I B draw point core 4 is placed in inlying catheter 2, allow with the convex of convex female Luer steel needle core handle 5
Female Luer is fitted close with the recessed female Luer with recessed female Luer needle stand 1, after then draw point core 4 pierces through skin and vascular wall
Inlying catheter 2 can be just guided to insert intravascular；After removing draw point core 4, by the recessed female Luer needle stand 1 of part II C insert bands
In, allow convex female Luer as received basis liquid capsule cap 7 to be fitted close with the recessed female Luer with recessed female Luer needle stand 1；
During transfusion, as received basis liquid capsule pipe 6 is not filled, treats that transfusion fluid passes through the intravasation of infusion channel 3；When stopping is infused
When, external liquid capsule 9 is pressurizeed, and as received basis liquid is filled in as received basis liquid capsule 6 and is kept its pressure, prevents blood reflux to transfusion
In passage 3.
A preferred embodiment of the invention, the recessed female Luer needle stand 1 of described band, inlying catheter 2, with convex Shandong
Your joint steel needle core handle 5, as received basis liquid capsule pipe 6, inside and outside liquid capsule communicating pipe 8 and outer liquid capsule 9 are all to use makrolon or polyethylene
It is manufactured.
According to another preferred embodiment of the present invention, shape after as received basis liquid capsule 6 is full with recessed female Luer
The cavity shape of needle stand 1 is identical, or high resiliency U-tube.
According to the present invention another preferred embodiment, the outer shape of liquid capsule 9 be cylinder, cuboid, ellipse or
It is circular.
The present invention is described in more detail below.
The intravascular remaining needle of malleation liquid capsule self-sealing of the present invention sets recessed female Luer, the recessed female Luer in needle stand tail end
Combined with convex female Luer steel needle core handle and carry out vascular puncture and place conduit, placed and finish in conduit, removal draw point core it
Afterwards, the recessed female Luer is combined with convex female Luer as received basis liquid capsule cap, and as received basis sac segment is in convex female Luer work
In matter liquid capsule cap, therefore, the as received basis liquid capsule that can be filled repeatedly is provided with needle stand.As received basis liquid capsule can when full
Closing infusion channel simultaneously provides lasting malleation.Different from physiological saline and heparin medicine tube sealing, present invention work liquid capsule utilizes
Infusion channel in fluid physics characteristic and thin-walled liquid capsule method closing needle stand, " as received basis liquid " is not lost in, can kept " malleation "
State.
The present invention relates to a kind of intravascular remaining needle of malleation liquid capsule self-sealing, it referring specifically to accompanying drawing 1.Malleation of the present invention
The intravascular remaining needle of liquid capsule self-sealing is mainly made up of main element A, part I B and part II C.
