Description
Technical field
It is particularly a kind of that there is the remaining needle for pushing the deposited wing of conduit activity the present invention relates to a kind of remaining needle.
Background technology
A kind of transfusion remaining needle for being connected with collateral road flexible pipe of the prior art as shown in figure 1, its by conduit tube component and
Needle tubing piercing assembly is constituted, and this remaining needle generally reduces puncture angle after needle point is pierced into blood vessel, and proficiency grip needle tubing is punctured
Component operation fin is motionless, and another hand props up branch road termination on the upside of catheter block by thumb finger tip, and conduit tube component is promoted forward,
Conduit is sent into blood vessel, because branch road periphery is smaller and short on the upside of catheter block, along with being connected with infusion tube, thumb
Contradict collateral terminal very inconvenient, and be also less prone to grasp conduit tube component push direction, easily occur beat, cause catheter tip
End scrapes blood vessel, causes blood vessel to abrade；Also this remaining needle is during indwelling, because catheter block rear portion is one time
Turn cylinder, and there is not small drop with catheter block front end, when pasting application, easily occur catheter block and upwarp, drive conduit
Also upwarp and pull point of puncture wound, moreover, when sufferer imprudence touches catheter block, can also upwarp, thus cause to wear
Thorn point oozing of blood problem.
Invention is constituted
It is an object of the invention to overcome weak point of the prior art, and offer one kind is easy to operate, be difficult to make blood vessel
Into a kind of remaining needle that there is push conduit activity to apply the wing of injury.
The purpose of the present invention is realized by following approach.
A kind of to have the remaining needle for pushing the deposited wing of conduit activity, including conduit tube component and needle tubing piercing assembly, its structure will
Point is：Also include a kind of deposited wing component of activity, the deposited wing component of activity includes the collar and fin, and the collar is socketed in catheter block back segment
On, fin is tangentially extending along the collar, itself or be pivotally connected or be fixedly connected with the collar with the collar, fin or by single
Soft medical material is made or is composited by skeleton and soft medical material.
So, in remaining needle before use, can turn to branch road on the upside of conduit tube component with operating fin on piercing assembly
It is overlapping, the deposited wing of activity is closed up.Treat that needle tubing is pierced into after blood vessel, reduction puncture angle, another hand can just consolidate grip activity
The wing is applied, conduit is slowly promoted forward, because grip is firm, conduit tube component is difficult beat, just conduit can steadily be sent into blood vessel.So
Afterwards, the wing is applied in expansion activity, and fin is close to skin, and the thickness because of fin is so as to make conduit tube component rear portion upwarp, after stickup is docile,
Make catheter block front end tilt all the time towards skin, will not occur conduit and upwarp to pull puncture wound, point of puncture would not ooze
Blood problem, simultaneously because there is the deposited wing to be close to skin, makes more firm during remaining needle indwelling, sufferer feels also more comfortable.
The purpose of the present invention can also be realized by following approach.
The bottom surface of fin is in an included angle A with respect to catheter block axis, and this included angle A make it that the bottom surface of fin is in respect to needle point direction
One acute angle.
So, but when applying wing bottom surface and skin paste and touching, it is able to make catheter proximal end slightly downward, so that conduit is more smoothed out
Plant in the blood vessel, will not upwarp and stab blood vessel.
The deposited wing component of activity has two collars and two fins respectively, and one-to-one corresponding is configured to two sets, and two sets of activities are applied
The wing is set axially back and forth along catheter block.
Catheter block second half section periphery time interval is provided with two raised baffle rings and applies the wing for installation activity, limitation is applied
The wing play and skids off catheter block backward forward.
In summary, the present invention has the following advantages that compared with prior art：Grip is consolidated, and conduit tube component is difficult beat, just
Conduit can steadily be sent into blood vessel, it is easy to use.Will not occur conduit and upwarp to pull puncture wound, point of puncture would not ooze
Blood problem, simultaneously because there is the deposited wing to be close to skin, makes more firm during remaining needle indwelling, sufferer feels also more comfortable.

Embodiment
Most preferred embodiment：
Reference picture 2 and Fig. 3, a kind of to have the remaining needle for pushing the deposited wing of conduit activity, it is by conduit tube component 1, needle tubing piercing assembly 2
Constituted with the deposited wing component 3 of activity.
Reference picture 4, Fig. 5, Fig. 6 and Fig. 7, wherein the deposited wing component 3 of activity is by the deposited deposited wing of the activity of the wing 3.1 and second of the first activity
3.2 are constituted, and each deposited wing of activity includes the collar 3.1.1,3.2.2 and fin 3.1.2,3.2.1 respectively, and the collar is socketed in catheter block
On back segment, fin is tangentially extending along the collar, and it is fixedly connected with the collar, fin or be made up of single soft medical material or
Person is composited by skeleton and soft medical material.Two fins arbitrarily can close up or deploy.
Reference picture 5, Fig. 7 and Figure 12, the bottom surface of fin is with respect to catheter block axis in an included angle A, and this included angle A causes fin
Bottom surface is in an acute angle with respect to needle point direction.
Reference picture 8, the catheter block second half section periphery be provided with two raised baffle ring 1.1.1 and 1.1.2, applied for installation activity
The wing, limitation applies the wing and play and skids off catheter block backward forward.
Remaining needle is assembled：
After the completion of conduit tube component is assembled, the deposited flush end of the wing 3.1 is first inserted in catheter block periphery towards duct direction, then, will be applied
The flush end of the wing 3.2 is directed away from conduit, is also inserted in catheter block periphery, is added up just due to rotating annular width on the two deposited wings with leading
Two raised baffle ring spacing are equal on base, so the deposited wing of activity would not before and after play, or abjection, as shown in Figure 9.Finally, will
Needle tubing piercing assembly passes through conduit tube component, exposes needle point, as shown in Figure 2 and Figure 3.
Remaining needle is used：
Operate fin overlapping with piercing assembly before use, branch road on the upside of conduit tube component can be turned in remaining needle, by work
The dynamic deposited wing closes up, and turns to opposite side, as shown in Figure 10.
Treat that needle tubing is pierced into after blood vessel, reduction puncture angle, another hand can just consolidate grip activity and apply the wing, slowly forward
Conduit is promoted, because grip is firm, conduit tube component is difficult beat, just conduit can steadily be sent into blood vessel.Then, expansion activity is applied
The wing, fin is close to skin, because of fin baseplane with conduit tube component axially with certain included angle A, so as to make on conduit tube component rear portion
Stick up, paste it is docile after, make catheter block front end tilt all the time towards skin, will not occur conduit and upwarp to pull puncture wound, wear
Oozing of blood problem would not occur for thorn point, simultaneously because there is the deposited wing to be close to skin, make more firm during remaining needle indwelling, sufferer is felt
Also it is more comfortable.
The not described part of the present embodiment is same as the prior art.
