Refering to fig. 1 shown in -3, a kind of angiocarpy radial artery contrast puncture needle, including paracentesis trocar 1 and needle core 2, needle core 2
It is detachably secured in paracentesis trocar 1；
The paracentesis trocar 1 is fixedly connected sequentially group by needle guard 11, coupling tube 12, clamping pipe 13 and clamping pipe eaves 14
At 11 surface of needle guard is equipped with inserting needle scale, and inserting needle scale prevents needle point from piercing through radial artery convenient for the piercing depth of grasp needle tubing 21
Vascular wall, the inner wall at the back outlet of clamping pipe 13 are equipped with limit stop ring 131, and the side of clamping pipe eaves 14 is fixed with pipe
It fills in, the seal wire insertion channel 151 of perforation is provided at 15 center of pipe close, pipe close 15 is connect by connecting rope with clamping pipe eaves 14；
The needle core is fixedly connected sequentially and is formed by needle tubing 21, needle tubing seat 22, storage blood vessel 23 and extension tube 24, needle tubing seat
22 be straight section and the integral structure that cone transitional section forms, and the front end of straight pipe is equipped with annular projection 221, and needle tubing 21 is embedded in
In needle tubing seat 22, the rear end of needle tubing 21 is concordant with the rear end of needle tubing seat 22, the straight section of the front end of needle tubing 21 from needle tubing seat 22
Front end is stretched out, and is fixed with barrier sheet 25 in extension tube 24, barrier sheet 25 is overrided to form by aseptic filter paper, and barrier sheet 25 can prevent
Blood anti-Hemostatic Oral Liquid in storage blood vessel 23 is barred from puncture process to go out from extension tube 24 and bacterium can be stopped from extension tube 24
It is middle to enter in storage blood vessel 23；Needle tubing 21 is inserted into needle guard 11 and the needle point of needle tubing 21 stretches out from the front end of needle guard 11, needle point slope
Angle is 30 °, and the needle tubing seat 22 of needle core 2 is fastened in the clamping pipe 13 of paracentesis trocar, is cased with rubber material on annular projection 221
Sealing ring 3, sealing ring 3 fits closely on the inner wall of clamping pipe 13.
One concrete application of the present apparatus are as follows: (1) patient body position: patient makes even clinostatism, arm overhanging, outreach in nature
Position, is supported on supporting plate；(2) sterile drape: conventional iodine flutters sterile drape, and sterilization scope includes entire palm, forearm, elbow joint
And 1/3 on elbow at；(3) selection of point of puncture: findding out radial artery traveling before puncture, preferably selects that radial artery pulse is strong, traveling is straight
Position punctures, point of puncture multiselect (processus styloideus radii inside proximal part 1~2cm at) away from 2~3cm of rasceta at, radial artery at this
It beats clear, and have certain distance away from wrist joint, is convenient for postoperative compression hemostasis；(4) local anaesthesia: first with 1%~2% benefit card
Because 0.5~1ml injects the small papule of diameter 1cm or so at skin penetrating position, pinpoint inclined plane is upward when inserting needle, substantially with
Skin is parallel, and avoids Superficial veins；(5) puncture pin puncture and establish intervention channel: the needle point slope surface of needle tubing 21 upward and is pierced into
Point of puncture is pierced into, while being observed in storage blood vessel 2 whether there is or not blood inflows, is observed on needle guard 11 when storing and flowing into blood in blood vessel 2
Inserting needle scale continues to stop being pierced into when 3~5mm of piercing, exits needle core 2 at this time, sealing ring 3 is with needle during exiting needle core 2
Tube socket 22 is gradually backed out clamping pipe 13, and sealing ring 3 generates negative pressure, needle tubing 21 and needle guard during exiting in clamping pipe 13
Air in 11 gaps and the blood that bubble is carried at the needle point of needle tubing are gone out in clamping pipe 13 by negative pressure drainage, prevent in radial artery
Form aeroembolism；As needle tubing seat 22 continues to exit, sealing ring 3 reach limit stop ring 131 at when be limited retaining ring 131 block and from
It backs off on annular projection 221, after needle core 2 exits paracentesis trocar 1 completely, pipe close 15 is jammed in the tail of clamping pipe 13 immediately
Portion, anti-Hemostatic Oral Liquid are gone out from clamping pipe tail portion, while insertion oar moves from the seal wire of pipe close 15 insertion channel 151 by J-type seal wire
