Specific embodiment
One specific embodiment of the utility model is set forth now in conjunction with attached drawing.
A kind of high-safety needle staying on vein, for the safeguard protection to used puncture needle 10 to avoid exposed puncture
Needle causes the case where stabbing, by pacifying to reply of the puncture needle 10 in needle tubing component 8 and under the action of card resistance component 9
It is locked entirely in needle tubing component, and is further protected by adding sheath 1 to projection seat 81, specific as follows:
With reference to attached drawing 1, a kind of high-safety needle staying on vein, including threeway conduit 2, needle tubing component 8 and puncture needle 10, puncture needle
10, which pass through threeway conduit 2, completes puncture effect, and pushes threeway conduit 2 to link up and complete to puncture effect, so that threeway conduit 2 stays
It is intravascular into human vein to set needle 21, the barrier blood of batching pig 3 is equipped in threeway conduit 2 in vein pressure subinverse and flow to vein
Outside remaining needle, the other end of threeway conduit 2 is infusion end 22, is connected to one end of long soft-pipe 4, the other end connection of long soft-pipe 4
To calparine cap 7, meanwhile, long soft-pipe 4 is equipped with the clamping element 6 of movable movement, and clamping element 6 is arranged simultaneously in magic power patch 6, with
It is convenient that the opposing stationary of the long soft-pipe 4 between clamping element 6 and threeway conduit 2 is kept in the case where needing situation of movement, extend remaining needle
Indwelling duration.
One end of puncture needle 10 is fixed on the Paracentesis needle holder 94 in needle tubing component 8, and with Paracentesis needle holder
94 move in needle tubing component 8, complete the movement for puncturing and pulling out needle, and Paracentesis needle holder 94 is connect with the needle wing 82, and the needle wing 82 is for convenience
The wing that medical staff punctures, the needle wing 82 drive Paracentesis needle holder 94 to act under the promotion of medical staff and then drive puncture needle 10
Movement.The leading portion of puncture needle 10 is provided with whether blood back mouth succeeds so that medical staff judges to puncture.
After completing puncture movement, puncture needle 10 is extracted by the needle wing 82, puncture needle 10 returns back under the action of the needle wing 82
Initial position, meanwhile, it is locked on initial position under the action of card resistance component 9, prevents puncture needle 10 from exposing needle again
Tube assembly 8 is outer to generate security risk.
The card resistance component 9 includes the two parts being oppositely arranged, and is illustrated now in conjunction with attached drawing 2 to a portion, is blocked
Resistance component 9 includes the button 91 being arranged on the tube wall of needle tubing component 8, by the sliding block 92 interconnected of spring 93, the cunning
Block 92 slides in the guide groove 83 being arranged on tube wall side wall, and in initial position, sliding block 92 is under the elastic force effect of spring 93
Button 91 is ejected, 91 side of button is provided with buckle 912, and the buckle 912 is equipped on the tube wall of needle tubing component 8
Card slot 84 in and the local movement in card slot 84.
One side of the button 91 inside needle tubing component 8 is inclined to 8 top (right side in view) of needle tubing component
Inclined-plane 911, the sliding block 92 towards the side of button 91 be set as inclined-plane 921 it is lower and face directly 922 upper connection one side,
Also, the button 91 is on locked position, and spring 93 pushes up button 91 to extreme position, sliding under extreme position at this time
One side of the block 92 towards button 91 is completely interior in the inner wall of needle tubing component 8, in this way, in the case where side button 91 touches accidentally,
The sliding block 92 of the other side is still stopped to guarantee locked safety not in downward actuation by the inner wall of needle tubing component 8.Meanwhile making
Used time, while pressing the button 91 of two sides and pulling the needle wing 82 that puncture movement can be completed.
One end of the sheath 1 is remaining needle interface end 11, to be set in the protective case on remaining needle, the other end before using
Puncture needle interface end 12 is set in the projection seat 81 of 8 lower end of needle tubing component after use for puncture needle interface end 12, it is ensured that
Even if realizing duplicate protection when puncture needle 10 exposes needle tubing component 8 again still under the protection of sheath 1.
Working principle: when puncture, pulling up sheath 1, and by lower button 91, simultaneously mobile 82 a distance of the needle wing makes sliding block simultaneously
92 leave locked position, push threeway rod action, indwelling when puncture needle 10 is completed to puncture under the action of guide groove 83 later
Needle 21 also completes puncture movement, and puncture needle 10 is extracted after medical staff observes blood back；After extracting puncture needle 10, in mobile needle
The wing 82 is returned to card resistance component 9 at locking position and completes locked movement, and under the elastic force effect of spring 93, sliding block 92 acts outward
Button 91 and partial embedding are bonded in the inner wall of needle tubing component 8, under the action of the fitting on inclined-plane, loses becoming for downward actuation
Gesture, also, even if when embedded 92 downward actuation of sliding block will be stopped by inner wall；Finally, by 12 end cap of puncture needle interface of sheath 1
It is located in the projection seat 81 of needle tubing component 8, protection of further revealing all the details.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
