The specific embodiment
From Fig. 1, Fig. 2, Fig. 3 as can be seen, a kind of safety blood taking pin, it includes needle tubing 4, needle stand 3.The double end needle tubing that needle tubing 4 is structure as a whole, needle tubing 4 runs through needle stand 3, closely cooperates with needle stand two ends pore, and is with epoxy resin that needle tubing and needle stand is bonding firmly.Needle tubing 4 one ends are venipuncture needle 41, and venipuncture needle 41 is positioned at the front end of needle stand, are used for venipuncture; The other end is cannula needle 42, is used for being connected cooperation with blood resistance unit and vacuum test tube and takes a blood sample.Blood resistance unit is enclosed within the cannula needle outside, and its opening is fixed on the needle stand 3.During assembling, the venipuncture needle 41 at needle stand two ends and cannula needle 42 outsides also can be provided with the needle tubing helmet.
Characteristics of the present invention are: described needle stand 3 is fixedly mounted in the adapter sleeve 2, the rotatable needle tubing retaining clip 1 of installing on the described adapter sleeve 2.
From Fig. 3, Fig. 4, as can be seen, circumferentially be provided with annular boss 32 on the described needle stand 3, be axially arranged with the protruding wing 31 of some anti-rotations, correspondingly be provided with the annular groove 23 that cooperates with annular boss 32 and the anti-rotation boss 22 that cooperates with the protruding wing 31 of anti-rotation in the described adapter sleeve 2.By cooperating of annular boss 32 and annular groove 23, limited moving axially of needle stand 3 relative adapter sleeves 2; Cooperate with the grafting of anti-rotation boss 22 by the protruding wing 31 of anti-rotation, limited needle stand 3 and rotated relative to the circumferential of adapter sleeve 2.Needle stand 3 is fixedly mounted in the adapter sleeve 2 reliably like this.
As can be seen, described adapter sleeve 2 outsides are provided with one and connect draw-in groove 21 from Fig. 4, Fig. 5, and needle tubing retaining clip 1 lower end is provided with the connecting axle 11 that is connected draw-in groove 21 cooperations with this.By connecting axle 11 and the cooperation that is connected draw-in groove 21, needle tubing retaining clip 1 rotatable adapter sleeve 2 outsides that are installed in.Described needle tubing retaining clip 1 is provided with adapter sleeve stationary jaw 12 and needle tubing draw-in groove 14.Specifically be the needle tubing draw-in groove 14 that needle tubing retaining clip 1 top is provided with outside sealing, the venipuncture needle 41 of the width of described needle tubing draw-in groove 14 and length and needle tubing 4 one ends is complementary, and is used for parcel venipuncture needle 41.Needle tubing retaining clip 1 lower inside is provided with the stationary jaw 12 that cooperates the location with shirt rim, adapter sleeve 2 top.Stationary jaw 12 is connected with shirt rim, adapter sleeve 2 top, can avoid the needle tubing retaining clip to come off from adapter sleeve.
From Fig. 5, it can also be seen that, both wings inboard, described needle tubing retaining clip 1 bottom be provided with cooperate with adapter sleeve hold boss 15 tightly.During packing, by holding boss 15 and 2 peripheral cooperations of adapter sleeve tightly, adapter sleeve can be pressed close to and hold tightly to the needle tubing retaining clip, reduces packaging volume, convenient transportation.
Laterally be provided with needle tubing claw 13 in the needle tubing draw-in groove 14 on the described needle tubing retaining clip 1.Needle tubing claw 13 horizontally sets, and certain elasticity is arranged.Under the effect of external force, venipuncture needle 41 is depressed needle tubing claw 13, pressed needle tubing claw 13 after, needle tubing claw 13 is upspring automatically, venipuncture needle 41 is blocked, this moment venipuncture needle 41 between needle tubing claw 13 and needle tubing draw-in groove 14 bottom surfaces.Needle tubing claw 13 can arrange a plurality of, effectively to push down venipuncture needle 41, improves safety coefficient.
The present invention pushes needle tubing retaining clip 1 to venipuncture needle 41 after taking a blood sample and puncturing successfully, under the effect of external force, venipuncture needle 41 is depressed the needle tubing claw 13 in the needle tubing draw-in groove 14, after pressing the needle tubing claw, the needle tubing claw is upspring automatically, and venipuncture needle is stuck in the needle tubing draw-in groove; Meanwhile, stationary jaw 12 on the needle tubing retaining clip 1 is fixed in inboard, shirt rim, adapter sleeve 2 top, the axis of needle tubing retaining clip overlaps with the axis of adapter sleeve, whole needle tubing retaining clip is clamped on the adapter sleeve reliably, the needle tubing retaining clip can be pinned venipuncture needle automatically, venipuncture needle is wrapped, as shown in Figure 2.Can not take off the needle tubing retaining clip this moment again from adapter sleeve and venipuncture needle, reach real disposable purpose, avoids secondary to use effectively, increased the blood sampling safety greatly.
Simple structure of the present invention, reasonable, it is easy to operate to take a blood sample, and use can effectively avoid stabbing medical worker and cleanup crew, and is safe, but also can avoid secondary to use effectively.
