Coordinating between described draw-in groove with described grip part is interference fit.
Described needle stand is cylindrical, and the width of described chute is less than the diameter of described needle stand, the length of needle stand be greater than draw-in groove along quill to length.
Also comprise hose, described hose comprises flexible tube base and flexible pipe, described flexible tube base comprises the first joint, the second joint and the 3rd joint, described first joint and the second joint are coaxially and mutually through, described flexible pipe is connected with described first joint, and described sleeve socket-connects away from one end of draw-in groove and described second joint.
Also comprise hose, described hose comprises flexible tube base and flexible pipe, and described flexible tube base is hollow structure, and described flexible tube base two ends arrange the first joint and the second joint respectively, described flexible pipe is connected with described first joint, and described sleeve socket-connects away from one end of draw-in groove and described second joint.
Adopt above technical scheme, the beneficial effect acquired by this utility model is:
This utility model provides a kind of remaining needle, and it can be protected in protective sleeve after puncture needle is finished using, and has draw-in groove; grip part can be blocked; thus puncture needle is locked in sleeve, prevent it from accidentally injuring other staff and cause infection, improve its safety.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, technology of the present utility model is described in further detail:
Fig. 1 is the structure chart (needle stand is positioned at chute foremost, and it is outer that needle point stretches out flexible pipe) of the remaining needle of this utility model embodiment 1;
Fig. 2 is the structure chart (pin base fastener in draw-in groove, extract from the second joint by sleeve) of the remaining needle of this utility model embodiment 1;
Fig. 3 is the structure chart of the remaining needle of this utility model embodiment 2.
Detailed description of the invention
Embodiment 1
As depicted in figs. 1 and 2, the remaining needle that the present embodiment provides comprises puncture needle component, the puncture needle 2 that described puncture needle component comprises needle stand 1 and is fixed on needle stand 1, needle stand 1 is provided with the grip part 3 for gripping, described puncture needle component also comprises sleeve 4, the axial direction of described sleeve 4 offers chute 41, chute 41 end offers the draw-in groove 42 that also grip part 3 can be blocked vertical with described chute 41, described puncture needle 2 and needle stand 1 are sheathed in sleeve 4, grip part 3 is stretched out sleeve 4 from chute 41, the front end of sleeve 4 is greater than the axial distance of puncture needle 2 needle point to center, grip part 3 to the axial distance at draw-in groove 42 center.Needle stand 1 can slidably reciprocate along the diametric(al) of sleeve 4 in sleeve 4, after puncture needle 2 punctures, grip part 3 to draw-in groove 42 position is moved along chute 41, grip part 3 is stuck in draw-in groove 42 by radial rotating grip part 3, thus needle stand 1 can be fixed relative to sleeve 4, and it is inner needle point to be limited to sleeve 4, can not other staff be stabbed and cause infecting.
Wherein, coordinating between draw-in groove 42 with grip part 3 is interference fit, can be stuck in draw-in groove 42 by grip part 3, is locked in sleeve 4 by puncture needle 2, prevents from needle stand 1 relative sleeve 4 from moving causing needle point to be exposed to sleeve 4 outer thus stab other staff.
Wherein, needle stand 1 is cylindrical, the width of chute 41 is less than the diameter of described needle stand 1, the length of needle stand 1 is greater than the width of draw-in groove 42, can needle stand 1 and puncture needle 2 be limited in sleeve 4, prevent it from deviating from sleeve 4, needle stand 1 tail end is also connected with guide pipe 8, can prevent needle stand 1 from deviating from further.
Wherein, the remaining needle of the present embodiment also comprises hose, described hose comprises flexible tube base 5 and flexible pipe 6, flexible tube base 5 comprises the first joint 51, second joint 52 and the 3rd joint 53, first joint 51 and the second joint 52 are coaxially and mutually through, flexible pipe 6 is connected with the first joint 51, sleeve 4 socket-connects away from one end of draw-in groove 42 and the second joint 52, 3rd joint 53 is positioned at the first joint 51 sidepiece, and connect with the first joint 51, 3rd joint 53 connects tube for transfusion 7, also cork is provided with in second joint 52, first joint 51 and the second joint 52 are isolated to form transfusing chamber in the first joint 51 by cork, and the effect of hemostasis can be played, the cork material being easy to lancet puncture is made.
Embodiment 2
As shown in Figure 3, for the structure chart of the another kind of embodiment of this utility model remaining needle, itself and the difference of embodiment 1 are that the structure of hose is different, the hose of the remaining needle of this embodiment comprises flexible tube base 5' and is arranged on the flexible pipe 2 of 5' on flexible tube base, described flexible tube base 5' is hollow structure, flexible tube base 5' comprises the first joint 51' and the second joint 52', flexible pipe 2 is connected with the first joint 51', sleeve 4 socket-connects away from one end of draw-in groove 42 and the second joint 52', also cork is provided with in second joint 52', first joint 51' and the second joint 52' isolates to form transfusing chamber in the first joint 51' by cork, and the effect of hemostasis can be played, the cork material being easy to puncture is made.
This utility model remaining needle in use, first moving grip part 3 along chute 41 drives puncture needle 2 to enter flexible pipe 6 through the second joint 52 and the first joint 51 successively, until the needle point of puncture needle 2 exposes flexible pipe 6, puncture needle 2 is penetrated vein, until flexible pipe 6 also enters vein, then grip part 3 to draw-in groove 42 is moved along chute 41, puncture needle 2 is exited hose, now, it is inner that puncture needle 2 is all positioned at sleeve 4, rotate grip part 3 grip part 3 to be stuck in draw-in groove 42 thus needle stand 1 relative sleeve 4 is fixed, again sleeve 4 is extracted in the second joint 52, because needle point is positioned at sleeve 4 inside, therefore can not cause and other staff are accidentally injured, infection can not be caused.
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to this utility model; although be described in detail this utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
