Abstract
The invention provides a disposable safe hemostix which comprises a casing and a drive triggering device. A torsion spring is rotatably connected at the lower portion of the casing, a casing opening is horizontally arranged in the upper portion of the casing, and the drive triggering device penetrates into the casing from the casing opening. A blood taking needle is horizontally arranged at one end of the torsion spring and is located on the lower portion of the drive triggering device, and the head of the blood taking needle points at the casing opening. After rotating and moving towards the outside of the casing, the drive triggering device pushes towards the interior of the casing to drive the torsion spring to compress. A limit rod for limiting the rotation of the drive triggering device is arranged on the inner wall of the casing. The disposable safe hemostix has the beneficial effects that after taking blood with this hemostix, the drive triggering device cannot return, so blood cross infection caused by repeated use of the hemostix is effectively prevented; after taking blood, the head of the blood taking needle remain in the casing, so people injury caused by misoperation is avoided; and when taking blood, the head of the needle does not protrude, so as to protect patients from psychological fear.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Such as Fig. 1-Fig. 5, the present invention proposes a kind of single use safe hemostix, including housing 1, drives driven triggering device, and described housing 1 lower rotational is connected to torsion spring 2；Described housing 1 upper level is provided with faucal 3, described in drive driven triggering device and stretch in described housing 1 from described faucal 3；Described torsion spring 2 one end has been horizontally disposed with blood taking needle 4, and drives driven triggering device bottom, faucal 3 described in described blood taking needle 4 head points described in being positioned at；Wherein, described in drive driven triggering device and include Trigger body 6, described Trigger body 6 center is provided with and excites groove 7, described torsion spring 2 upper end stretch into described in excite in groove 7；Described Trigger body one end is provided with exciting port gear and protects 8, and the other end is provided with percussion push and block 9, and described percussion push and block 9 side is provided with inclined-plane 10.
This drive driven triggering device can in this housing 1 rectilinear motion, and torsion spring 2 movable end displacement circular motion can be driven, and launch at incline position release torsion spring 2, drive blood taking needle 4 motion to protrude housing 1 one end open of hemostix, faucal 3 and blood taking needle 4 joint are right angle.
The working method of the present invention is: as shown in Figure 1; time in the raw without energy accumulating state; the Trigger body 6 driving driven triggering device stretches in housing 1; and exciting port bib is stuck in faucal 3 place; being blocked by whole faucal 3, now, mouthful bib that is excited of the blood taking needle 4 in faucal 3 blocks; to 4 needle point protective effects of blood taking needle, it is prevented that pollute or maloperation；
nullWorking method during use is: such as Fig. 2、Fig. 3、Fig. 4，Pulled by external force and drive driven triggering device，Until being pulled to the front portion of torsion spring 2，Half-twist again，Exciting port bib is made to be in level，After rotation，Percussion push and block 9 are pressed on the end of torsion spring 2，Trigger body 6 is provided with the fixture block 11 coordinated with described gag lever post 5 herein，Fixture block 11 turns to gag lever post 5，Namely not rotatable，Now torsion spring 2 upper end is pressed in percussion push and block 9，Trigger body 6 is advanced again in housing 1，Press torsion spring 2，Torsion spring 2 rotates along jump ring post 12，Torsion spring 2 has saved portion of energy，When Trigger body 6 continues to advance，Slide along the inclined-plane 10 of percussion push and block 9 bottom gradually in the end of torsion spring 2，Release torsion spring 2 gradually，Depart from and excite groove，And it is movable along Trigger body lateral wall，Drive the transmitting of blood taking needle 4，Bigger power due to torsion spring 2 savings，Blood taking needle 4 can be launched to faucal 3，And extend slightly from faucal 3，Faucal 3 alignment blood sampling skin place，Skin can be punctured；
Wherein, being perpendicularly oriented to described faucal place plane after the release of described blood taking needle 4, blood taking needle 4 vertically penetrates, and perpendicularity is more high be ensure that, during blood sampling, the pain of people is more low.
Trigger body 6 now has been fully inserted in housing 1, owing to described exciting port gear protects 8 for rectangle, the width that described exciting port gear protects 8 is identical with the height of described faucal 3, and can stretching in faucal 3, such as Fig. 5, described faucal 3 is provided with for limiting the back-off driving driven triggering device, by back-off by spacing for Trigger body 6, cannot exiting again, can realize driving the locking of release device, restriction hemostix is reused.
Preferably, described housing 1 bottom is provided with jump ring post 12, and sidewall is provided with locating slot 13, and described torsion spring 2 is placed in described jump ring post 12, and the one end not installing blood taking needle 4 is stuck in described locating slot 13, it is ensured that torsion spring 2 compressed energy-storage.
The multiple amendment of embodiment be will be apparent from for those skilled in the art, and generic principles defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
