As shown in figure 12, be provided with in the handwriting 1 one with the depression bar cover 33 columnar pen core transposase 19s that are connected, the pen core transposase 19 is enclosed within the outside of depression bar cover 33 and opening core bar 6.The medial wall of depression bar cover 33 is provided with one or more and is parallel to muscle 333 in the depression bar that depression bar overlaps 33 central shafts, the outward flange of the flange 321 of pushing rod sleeve 32 be provided with more than one with depression bar in muscle 333 corresponding flange grooves 3211.The lateral wall of the outer shoulder 331 of depression bar cover is provided with one or more and is parallel to the outer muscle 334 of depression bar that depression bar overlaps 33 central shafts, the sidewall on pen core transposase 19 top is provided with the slit 91 of the outer muscle 334 of one or more corresponding depression bar, the outer muscle 334 of depression bar is stuck in the slit 91, positioning tooth torus 82 is enclosed within the outside of pen core transposase 19, the medial wall of positioning tooth torus 82 is provided with a buckle 821, described buckle is corresponding with the slit of the outer muscle of described depression bar, also is stuck in the slit 91.So that the cap for brush 8 is when turning an angle, positioning tooth torus 82 positions are motionless, can not driven and rotate by the cap for brush 8.Effect owing to the 4th spring 74 after the cap for brush 8 turns an angle also can be stuck on the positioning tooth torus 82.
Can drive the pen core transposase 19 and turn an angle yet, all parts in the drive rod 3 can not rotate.The 4th spring 74 can be so that pen core transposase 19 and the cap for brush 8 after rotating still be fixed together.
Such as Fig. 2, shown in Figure 13, an annulus is formed on the bottom of pen core transposase 19, and the trisection point of this annulus is respectively equipped with an inside claw 22.Nib is provided with a rotating pallet 21 in 2, and pallet 21 is provided with equally distributed pen core 5 more than two, and the edge of pallet 21 is provided with three equally distributed, corresponding with claw 22 breach 23.User rotates the cap for brush 8, can drive pallet 21 by the pen core transposase 19 and rotate.Nib 2 outer surfaces are provided with gear adjusting knob 24, and gear adjusting knob 24 is connected to the pen core transposase 19, and user will be with the pen core displacement of crossing by rotating the cap for brush, and gear adjusting knob 24 is convenient to the gear after the user understanding adjustment, adjust simultaneously a new pen core stand-by.It is 0.1 millimeter dialyzing paper 53 that pallet 21 upper surfaces are provided with a layer thickness, and written 2 ends are provided with a layer thickness over against blood collection needles 51 places be 0.1 millimeter plastic layer 54, keeps cleaning in the pen core and not contaminated.
Preferred version is as follows, and pallet 21 is provided with six equally distributed pen cores 5, and the edge of pallet 21 is provided with six equally distributed, corresponding with claw 22 breach 23, and adjacent two pen cores 5 are all 60 degree with the angle of pallet 21 central shaft lines.
The present invention at work, with blood sampling place of nib on the quilt blood sampling person skin, the staff presses hands 7, and keep pinning state and do not put, the first spring 71, the second spring 72, the 3rd spring 73, the 5th spring 75 are simultaneously compressed, depression bar overlaps 33 pushing syringes 4 and moves downward, so that the injection joint 41 of syringe 4 puncture dialyzing paper 53 be connected to the below needle stand 511 on, the lower end of drive rod 3 enters into syringe 4 simultaneously, in the exhaustjet device 4 and the air in the syringe needle 51, and then needle point 512 punctures plastic layer 54.Needle point 512 thrusts by in blood sampling person's the blood vessel, loosens and presses hands 7, and each spring reset drives each descending parts and resets, and needle point 512 is retracted.Because the second spring 72, the 3rd spring 73 restore to the original state at first, in drive rod 3 uphill process, a small amount of blood sample can be extracted to blood collection needles 51, be kept in the needle stand 511, after drive rod 3 resets, the 4th spring 64 restores to the original state, syringe 4 also can rise, so that injection joint 422 separates with needle stand 511, the 5th spring 65 restores to the original state then, needle point 512 is retracted in the nib 2, and blood sampling is finished.After each several part resetted, the gear adjusting knob on the rotating nib was so that another group pen core is over against the injection joint 422 that should inject key 42, to treat that next time, blood sampling was used.
In the nib 2 six pen cores 5 are arranged, after continuous six blood samplings of user, open nib, with the pen core that pen core 5 is taken out and more renewed, need not all will change after each blood sampling, simple to operate, easy to use.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
