Summary of the invention
This utility model purpose is: a kind of safe type retention needle is provided, not influencing the remaining needle use, does not need to increase under the prerequisite of healthcare givers's transfusion operation step, increased protective sleeve for the needle tubing tip, make it not dangerous.
The technical solution of the utility model is: a kind of safe type retention needle; comprise the notch needle tubing; catheter block; conduit is located at the side handle and the oversheath of notch needle tubing afterbody, and described catheter block rear portion is provided with the protective sleeve that cooperates with the catheter block inwall; the protective sleeve inboard is provided with jump ring; when notch needle tubing front end walked to the jump ring place, the jump ring inlay card was in the side channel mouth, and the notch needle tubing is most advanced and sophisticated not in protective sleeve inside.
The further technical scheme of this utility model is: a kind of safe type retention needle, comprise the notch needle tubing, catheter block, conduit is located at the side handle and the oversheath of notch needle tubing afterbody, and described catheter block rear portion is provided with the protective sleeve that cooperates with the catheter block inwall, the protective sleeve inboard is provided with jump ring, when notch needle tubing front end walked to the jump ring place, the jump ring inlay card was in the side channel mouth, and the notch needle tubing is most advanced and sophisticated not in protective sleeve inside; Described protective sleeve also comprises convex round platform outer tube, is fixed in the interior pipe of narrow inboard of round platform outer tube; Be provided with hermatic door between wide of round platform outer tube and the narrow portion, jump ring is fixed in narrow by in the formed space of hermatic door and inner tube portion; Wide external diameter of described round platform outer tube is greater than the internal diameter of catheter block, and wide internal diameter cooperates with side handle handle medicated cap front end external diameter.
The technical scheme that this utility model is more detailed is: a kind of safe type retention needle, comprise the notch needle tubing, catheter block, conduit is located at the side handle and the oversheath of notch needle tubing afterbody, and described catheter block rear portion is provided with the protective sleeve that cooperates with the catheter block inwall, the protective sleeve inboard is provided with jump ring, when notch needle tubing front end walked to the jump ring place, the jump ring inlay card was in the side channel mouth, and the notch needle tubing is most advanced and sophisticated not in protective sleeve inside; Described protective sleeve also comprises convex round platform outer tube, is fixed in the interior pipe of narrow inboard of round platform outer tube; Be provided with hermatic door between wide of round platform outer tube and the narrow portion, jump ring is fixed in narrow by in the formed space of hermatic door and inner tube portion; Wide external diameter of described round platform outer tube is greater than the internal diameter of catheter block, and wide internal diameter cooperates with side handle handle medicated cap front end external diameter; Described jump ring forms, comprises four limits for both sides, long limit all have the rectangular metal sheet of symmetrical trapezoidal reed to fold, and each limit comprises the trapezoidal reed of a webbing and webbing two ends invagination again.
This utility model advantage is:
1. this utility model is given and to be put that let the acupuncture needle remain at a certain point has added sheath, automatically the needle point of front end danger is screened when needle tubing is pulled out, and bring injury can not for sufferer or other people, has also reduced the probability of staying syringe tip end viral communication.
2. this utility model need not additionally increase healthcare givers's transfusion operation step, and need not especially note carefully placing needle tubing, and is convenient and practical.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further described:
Fig. 1 is this utility model structural representation;
Fig. 2 is the duty front view of protective sleeve;
Fig. 3 is the part of the duty right view of protective sleeve;
Fig. 4 is near the not sectional elevation jump ring in working order time of protective sleeve;
Fig. 5 is near the protective sleeve sectional elevation jump ring in working order the time;
Wherein: 1 notch needle tubing; 11 side channel mouths; 12 tips; 2 catheter blocks; 3 conduits; 4 side handles; 41 handle medicated caps; 5 oversheaths; 6 protective sleeves; 61 jump rings; 611 trapezoidal reeds; 612 webbings; 62 round platform outer tubes; 621 narrow portions; 622 wide portions; 623 hermatic doors; Pipe in 63; 7 batching pigs.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; a kind of safe type retention needle; comprise notch needle tubing 1; catheter block 2, conduit 3 is located at the side handle 4 and the oversheath 5 of notch needle tubing 1 afterbody; catheter block 2 rear portions are provided with the protective sleeve 6 that cooperates with catheter block 2 inwalls; protective sleeve 6 comprises jump ring 61, convex round platform outer tube 62 and interior pipe 63, and wherein round platform outer tube 62 comprises the hermatic door 623 between narrow 621, wide 622 and the narrow/wide portion 621,622 again.
Jump ring 61 forms, comprises four limits for both sides, long limit all have the rectangular metal sheet of symmetrical trapezoidal reed 611 to fold, and each limit comprises a webbing 612 again and is positioned at the trapezoidal reed 611 of webbing 612 two ends and invagination.
62 wide 622 external diameters of round platform outer tube are greater than the internal diameter of catheter block 2, and wide 622 internal diameter cooperates with side handle 4 handle medicated caps 41 front end external diameters; In pipe 63 usefulness glue be fixed in narrow 621 inboard, jump ring 61 is fixed in narrow 621 by in the formed space of hermatic door 623 and interior pipe 63 ends.
During use, when the healthcare givers finishes the puncture action to sufferer, when notch needle tubing 1 is extracted, in case notch needle tubing 1 front end walks to jump ring 61 places, trapezoidal reed 611 on the jump ring 61 just can slightly launch and inlay card in side channel 11, because jump ring 61 has four pairs of trapezoidal reeds 611, so the side channel 11 of notch needle tubing 1 is torqued into and arbitrarily angledly all can be stuck; After this again toward the outside when pulling out notch needle tubing 1, protective sleeve 6 can be because stuck in side channel 11 and along with notch needle tubing 1 front end is extracted together, this moment notch needle tubing 1 most advanced and sophisticated 12 not in protective sleeve 6 inside, no longer have danger.
For the remaining needle that batching pig 7 is arranged, as shown in Figure 1, protective sleeve 6 places batching pig 7 rear ends.
Like this, when pulling out needle tubing, automatically the needle point of front end danger is screened this utility model, bring injury can for sufferer or other people, also reduced the probability of staying syringe tip end viral communication, make medical personnel need not especially note carefully placing needle tubing, and can not change the use habit of vein puncture, convenient and practical.
