Using sting device X to pierce through under the situation of skin, at first, shown in Fig. 1 and Figure 15 C, the 31C of latch hook portion that makes movable plate 31 be on the protuberance 21a that is combined in framework 2 state (arrested state) afterwards, lancet support 32 is installed lancets 1.Wherein, also can after lancet 1 is installed in lancet support 32, movable plate 31 be locked on the framework 2.
Shown in Figure 15 A～Figure 15 C,, can move towards puncture direction N1 by the operating portion 31B that makes movable plate 31 and realize for arrested state.
Make movable plate 31 under the situation that puncture direction N1 moves from state shown in Figure 15 A, shown in Figure 15 A and Figure 15 B, the whole linkage component 30 that comprises the second movable pin 30b is that the center turns clockwise with steady pin 30c, and lancet support 32 lifts keeping out of the way on the direction N2.Further make movable plate 31 under the situation that puncture direction N1 moves from state shown in Figure 15 B, shown in Figure 15 C, linkage component 30 continues rotation in the clockwise direction, and lancet support 32 is pressed on puncture direction N1.At this moment, coil spring Sp is stretched, and keeps out of the way under the state of direction N2 in movable plate 31 trends, and the 31C of latch hook portion of movable plate 31 is combined on the protuberance 21a of framework 2.
On the other hand, under the situation that lancet 1 is installed, at first, as shown in Figure 2, take off second sleeve pipe 22 from first sleeve pipe 21, the contained portion 39 of lancet support 32 is in exposes state.Then, lancet 1 is inserted by restraining portion 39 from the direction opposite with puncture needle 11.At this moment, as shown in Figure 14B, the end face of lancet 1 contacts the pin 34b of second parts 34, and second parts 34 move to keeping out of the way direction N2 with the extrusion parts 50 of lancet output mechanism 5.Under the situation that second parts 34 move a certain distance, the end face of lancet 1 contacts the 38B of wall portion of first parts 33, being prevented to keeping out of the way the mobile of direction N2 of lancet 1.At this moment, the protuberance 34C of second parts 34 embeds the recess 37Aa of first parts 33.Like this, second parts 34 are by being pressed on first parts 33, and lancet 1 is sandwiched between first and second parts 33,34, and the hold mode of the lancet 1 in the lancet support 32 obtains reliable and stable.In addition, the collision sense when embedding recess 37Aa by protuberance 34C can know reliably that lancet 1 has been inserted into the target location.Therefore, it is insufficient that the insertion of lancet 1 can not become, and, can not cause that paracentesis depth unnecessarily increases, therefore, can puncture safely.
Under the situation that the installation of the stop of movable plate 31 and lancet 1 finishes, shown in Fig. 6 A, Fig. 6 B and Figure 13 A～Figure 13 C, by press stop cancel system 4 by bottom 42, carry out the puncture of skin.Under situation about supressing, comprise that the swing part 40 by bottom 42 and service portion 43 is that fulcrum moves to the inside of framework 2 with fixed part 41A by bottom 42.Like this, shown in Figure 13 B, the service portion 43 contact latch hook 31C of portion, the 31C of latch hook portion is forced to displacement, moves to an inner side, and therefore, the state (arrested state) that the 31C of latch hook portion is combined in protuberance 21a is disengaged.
As mentioned above, under arrested state, movable plate 31 trends are kept out of the way direction N2, therefore, under the situation that arrested state is disengaged, shown in Figure 15 C and Figure 15 D, movable plate 31 moves to keeping out of the way direction N2, accompany with it, linkage component 30 rotates in the clockwise direction, and lancet support 32 is pressed to puncture direction N1.Thereafter, movable plate 31 continue to move to keeping out of the way direction N2, accompanies with it, and lancet support 32 is lifted keeping out of the way on the direction N2, and shown in Figure 15 A, lancet support 32 revert to the free position that is locked in before the framework 2.Like this, extract lancet 1 from skin.
Under the situation that puncture procedure finishes, cluster needling blood needle rack 32 takes off lancet 1.Lancet 1 take off operation, shown in Figure 14 A and Figure 14 B, undertaken by lancet output mechanism 5.That is, move to puncture direction N1, come cluster needling blood needle rack 32 to take off lancet 1 by the operating portion 51 that makes lancet output mechanism 5.
Under the situation that operating portion 51 is moved towards puncture direction N1, service portion 52 moves to puncture direction N1, this service portion 52 contact baffle portion 34B.Under this contact condition, continuing to make operating portion 51 under the situation that puncture direction N1 moves, by service portion 52 to the power of baffle portion 34B effect towards the direction N1 that punctures.Under the situation to the power more than the baffle portion 34B effect necessarily, the chimerism between the recess 37Aa of the protuberance 34C of second parts 34 and first parts 33 is disengaged, and second parts 34 are forced to puncture direction N1 and move.Like this, the end face of lancet 1 is pressed by the pin 34b of second parts 34, and lancet 1 is forced to puncture direction N1 and moves.At this moment, protuberance 34C deviates from from recess 37Aa, and therefore, the strength that the arch bridge 34A of second parts 34 pushes lancet 1 diminishes, and to the big power of lancet 1 effect, just easily cluster needling blood needle rack 32 does not take off lancet 1.
In above-mentioned sting device X, about lancet support 32, the tight mode that connects the guide surface 38A of first parts 33 and relatively move of arch bridge 34A of second parts 34 has been described, but for the lancet support is maintained lancet, also can constitute like this: if can be just enough lancet effect pressing force, for example, shown in Figure 16 A and Figure 16 B or Figure 16 C and Figure 16 D, by making second parts 34 ', 34 " arch bridge 34A '; 34A " with respect to first parts 33 ', 33 " guide surface 38A '; 38A " via relatively moving at interval, make second parts 34 ', 34 " arch bridge 34A '; 34A " be indexed to an inner side, thus make arch bridge 34A ', 34A " push lancet 1.
More particularly, lancet support shown in Figure 16 A and Figure 16 B 32 ' constitutes like this: the recess 37Aa ' by the protuberance 34C ' that makes second parts 34 ' embeds first parts 33 ' makes arch bridge 34A ' to an inner side displacement.
On the other hand, lancet support 32 shown in Figure 16 C and Figure 16 D " with respect to second parts 34 " be provided with and embed first parts 33 " and recess 37Aa " protuberance 34C " different another protuberance 34D ", on the other hand, for first parts 33 ", be provided be used to contact protuberance 34D " protuberance 37B ".Protuberance 37B " to inner one side-prominent, its summit is positioned at than second parts 34 " protuberance 34D " an also inner side.Like this, when making second parts 34 " near first parts 33 " direction on relatively move, make second parts 34 " protuberance 34D " contact first parts 33 " and protuberance 37B " situation under, second parts 34 " arch bridge 34A " be indexed to an inner side.
In the present invention, adopt such formation: second parts of lancet support are combined on first parts, come lancet effect pressing force, for example can adopt the structure shown in Figure 17 A～Figure 17 C or Figure 18 A and Figure 18 B by second parts.

The 4th embodiment
Below, the 4th embodiment of the present invention is described.In the present embodiment, other modes to the lancet support describe.
As shown in figure 21, lancet support 8 has relatively-movable first and second parts 80,81 mutually.
As Figure 22 and shown in Figure 23, first parts 80 comprise cradle portion 82, constriction 83 and guide portion 84.
Restrain the moving that portion 83 is used to limit lancet 1 to radial direction.Should restrain portion 83 and form and cradle portion 82 ring-shaped continuous, its internal diameter is bigger slightly than the external diameter (internal diameter of cradle portion 82) of lancet 1.
As Figure 21 and shown in Figure 22, guide portion 84 is used to guide moving of aftermentioned second parts 81, and it has sliding part 88a.Extend to form two 88b of pedestal portion from sliding part 88a, between sliding part 88a and the 88b of pedestal portion, be formed with gap 88c.
As Figure 21 and shown in Figure 24, second parts 81 are puncturing and are keeping out of the way on direction N1, the N2 and move along the sliding part 88a of first parts 80.These second parts 81 are provided with columnar portion 89b in the end of flat part 89a, and have the form that lip portions 89c stretches out.
From Figure 25 A, Figure 25 B, Figure 26 A and Figure 26 B as can be known, columnar portion 89b is used for the interval that contacts lancet 1 and enlarge the gap 86B of first parts 80.The width of main 86Ba among the external diameter ratio gap 86B of this columnar portion 89b is big slightly, and its outside corresponding the interior shape of breach 86Bb of first parts 80.Lip portions 89c is the part that moves at the gap 88c of first parts 80, is guided by the 88b of pedestal portion of first parts 80.
The installation of the lancet 1 on lancet support 8 is performed such: insert lancet 1 from the direction opposite with puncture needle 11 (with reference to Figure 23) by restraining portion 83.At this moment, shown in Figure 25 A and Figure 26 A, in lancet support 8, because the columnar portion 89b of second parts 81 is positioned at main the 86Ba of the gap 86B of first parts 80, therefore, gap 86B is in expanded state.Under situation about inserting more than lancet 1 certain distance, the end face of lancet 1 contacts with columnar portion 89b, and columnar portion 89b moves along keeping out of the way main the 86Ba of direction at gap 86B.Under situation about inserting more than lancet 1 certain distance, shown in Figure 25 B and Figure 26 B, the end face of lancet 1 contacts the baffle portion 87 of first parts 80, being prevented to keeping out of the way the mobile of direction N2 of lancet 1.At this moment, columnar portion 89b embeds the breach 86Bb of first parts 80.Like this, but moving plate 86 is indexed to an inner side, and the size of gap 86B diminishes, but the moving plate 86 of first parts 80 is pushed lancet 1.In addition, embed breach 86Bb by columnar portion 89b, user hits sense and can know that lancet 1 is installed on the lancet support 8 reliably by touching.
On the other hand, cluster needling blood needle rack 8 takes off lancet 1, is undertaken by second parts 81 are moved to puncture direction N1.For moving of second parts 81, utilize lancet output mechanism 5 grades of explanation in the first embodiment to carry out.
That is, when the state that makes columnar portion 89b embed breach 86Bb from columnar portion 89b under the situation that puncture direction N1 moves, the embedding state of columnar portion 89b is disengaged, columnar portion 89b moves in main the 86Ba of gap 86B.At this moment, because main the 86Ba of gap 86B is extended, but moving plate 86 is indexed to the outside, and therefore, but moving plate 86 is pushed the power of lancet 1 and diminished.Like this, easily cluster needling blood needle rack 8 takes off lancet 1.
The structure of the gap 86B of first parts 80 and the columnar portion 89b of second parts 81 is not limited to above-mentioned embodiment.That is,,, in addition, on the 86B of gap, breach may not be set as long as have the little part of width dimensions for the width dimensions of gap 86B compared with columnar portion 89b.
The 5th embodiment
Below, the 5th embodiment of the present invention is described.In the present embodiment, other modes to the lancet support describe.
As shown in figure 27, lancet support 8C have with the 4th embodiment that illustrates previously in the similar form (with reference to Figure 21 and Figure 22 etc.) of lancet support 8, have the relatively-movable first and second parts 80C, 81C mutually.In the first parts 80C, but moving plate 86C is provided with two circular-arc breach 86Ca, 86Cb, and gap 86CA is provided with big width dimensions at its both ends respectively.In addition, in the first parts 80C, omitted the contained portion 83 (with reference to Figure 21 and Figure 22 etc.) in the lancet support 8 that illustrates previously.On the other hand, the second parts 81C make with lancet support 8 in the same structure of second parts 81.
But the breach 86Ca of moving plate 86C plays the same effect of breach 86Bb (with reference to Figure 21 and Figure 22 etc.) with the lancet support 8 that illustrates previously.That is, breach 86Ca is the part that the columnar portion 89Cb of the second parts 81C embeds, and constitutes like this: when lancet 1 (with reference to Figure 28 A～Figure 28 C) is fixed on the lancet support 8C, can obtains to touch and hit sense.On the other hand, breach 86Cb is when cluster needling blood needle rack 8C discharges lancet 1, the part that columnar portion 89Cb is embedded.That is, sense is hit in touching when user embeds breach 86Cb by columnar portion 89Cb, and can know that lancet 1 (with reference to Figure 28 A, Figure 28 B, Figure 28 C) is discharged from.
Shown in Figure 28 A～Figure 28 C, lancet support 8C installed lancet 1 is performed such: be positioned at the columnar portion 89Cb of second parts 81 under the state of breach 86Cb of the first parts 80C,, insert lancet 1 from the direction opposite with puncture needle 11.At this moment, shown in Figure 28 A and Figure 28 B, in lancet support 8C, lancet 1 contact columnar portion 89Cb, columnar portion 89Cb keeps out of the way direction N2 in main the 86CA ' introversion of gap 86CA and moves.Like this, the interval of gap 86CA is compared with naturalness and extended.Under the situation that lancet 1 moves a certain distance, shown in Figure 28 B and Figure 28 C, the end face of lancet 1 contacts the baffle portion 87C of the first parts 80C, and lancet 1 is prevented to keeping out of the way the mobile of direction N2.At this moment, columnar portion 89Cb embeds the breach 86Ca of the first parts 80C.Like this, but moving plate 86C is indexed to an inner side, and the width of gap 86CA diminishes, but the moving plate 86C of the first parts 80C pushes lancet 1.In addition, embed breach 86Ca by columnar portion 89Cb, user hits sense and can know that lancet 1 is installed on the lancet support 8C reliably according to touching.
On the other hand, to take off lancet 1 be to be undertaken by the second parts 81C is moved to puncture direction N1 to cluster needling blood needle rack 8C.The second parts 81C moves, and the lancet output mechanism 5 (with reference to Figure 14 A and Figure 14 B) that utilization illustrates in the first embodiment etc. carries out.
Make columnar portion 89Cb embed the state of breach 86Ca from columnar portion 89Cb under the situation that puncture direction N1 moves, can infer from Figure 28 B and Figure 28 C, the embedding state of columnar portion 89Cb is disengaged, and columnar portion 89Cb moves in main the 86CA ' of gap 86CA.At this moment, main the 86CA ' of gap 86CA is extended, but moving plate 86C is indexed to the outside, so, but pushing the power of lancet 1, moving plate 86C diminishes.Can infer from Figure 28 A and Figure 28 B, make columnar portion 89Cb under the situation that puncture direction N1 moves, but because moving plate 86C pushes the power of lancet 1 diminishes, so lancet 1 cluster needling blood needle rack 8C is discharged from.At this moment, columnar portion 89Cb embeds breach 86Cb.Sense is hit in touching that user obtains when embedding breach 86Cb by columnar portion 89Cb, and can know that lancet 1 cluster needling blood needle rack 8C is removed.
But the mode of the breach 86Cb of the moving plate 86C that illustrates previously for example, shown in Figure 29 A～Figure 29 F, can be carried out various changes.Breach 86Db～86Ib shown in these figure makes such form: close to puncture direction N1 more, it is big more that the width dimensions of gap 86DA～86IA becomes.
More particularly, the breach 86Db shown in Figure 29 A, the 86Dc of the section of possessing portion, by the 86Dc of section portion, the width dimensions of gap 86DA is enlarged by stage ground.The a plurality of sections 86Ec of portion of breach 86Eb shown in Figure 29 B form the stage shape, and by a plurality of sections 86Ec of portion, gap 86EA enlarges width dimensions on a plurality of stages.Breach 86Fb～86Ib possesses conus portion 86Fc～86Ic shown in Figure 29 C～Figure 29 F, and by conus portion 86Fc～86Ic, the width dimensions of gap 86FA～86IA is enlarged continuously.
But possess at moving plate 86D～86I under the situation of breach 86Db～86Ib, when columnar portion 89Db～89Ib embeds breach 86Db～86Ib, but because moving plate 86D～86I revert to naturalness, so the elastic force of this moment acts on columnar portion 89Db～89Ib.Therefore, but act under the situation of columnar portion 89Db～89Ib at the elastic force that produces from moving plate 86D～86I, this elastic force becomes propulsive force, columnar portion 89Db～89Ib and even second parts 81D～81I are to puncture direction N1 fast moving, and lancet 1 (with reference to Fig. 2) may fly out by cluster needling blood needle rack 8D～8I.
In contrast, in possessing lancet support 8D～8I of the illustrative breach 86Db～86Ib in front, breach 86Db～86Ib at columnar portion 89Db～89Ib when puncture direction N1 moves, the interval of gap 86DA～86IA continuously or stage ground narrow down.Like this, but moving plate 86D～86I can not revert to naturalness apace, but revert to naturalness lentamente.Its result, can be not sharp to power that columnar portion 89Db～the 89Ib effect is big.Therefore, lancet support 8D～8I can avoid lancet 1 to fly out when discharging lancet 1 (with reference to Fig. 2).
But, possessing on breach 86Fb～86Ib of conus portion 86Fc～86Ic, for the effect that obtains reliably to illustrate previously, preferably gently set the inclination of conus portion 86Fc～86Ic with respect to puncture direction N1, angle of inclination with respect to conus portion 86Fc～86Ic of puncture direction N1 for example is set at 10～45 degree.
But the moving plate 86, the 86C～86I that illustrate in four embodiment of the invention and the 5th embodiment not necessarily are provided with a pair of.For example, as shown in figure 30, also can construct lancet support 8J: cradle portion 82J like this and have fixed part 86Ja and between this fixed part 86Ja, separate the movable part 86Jb that gap 86JB is provided with.In this structure,, can make movable part 86Jb that displacement is taken place fixed part 86Ja by in main the 86JBa of gap 86JB, the columnar portion 89Jb of the second parts 81J being moved.Like this, the power that movable part 86Jb pushes lancet 1 diminishes, and easily cluster needling blood needle rack 8J takes off lancet 1.
In addition, among the lancet support 8K, to the outside displacement taking place in order to make movable part 86K shown in Figure 31 A and Figure 31 B, is provided with taper surface 81KA in the end of the second parts 81K.In this structure, when moving the second parts 81K, because the position that contacts with movable part 86K among the taper surface 81KA changes, therefore, displacement can take place in movable part 86K.
The invention is not restricted to above-mentioned embodiment, can carry out various design alterations.For example, construct like this among the sting device X: to movable plate 31 elastic force of coil spring Sp is played a role, lancet support 32 is moved, but, both can construct like this: use coil spring Sp elastomeric element in addition,, also can construct like this movable plate 31 effect elastic force; Utilize driving forces such as Air Force or electromagnetic force that movable plate is moved.In addition, also can construct like this: omit movable plate, make driving force directly act on the lancet support, the lancet support is moved.
In each embodiment, with the situation that forms second parts of lancet support as the mode different with the miscellaneous part of the extrusion parts 50 that comprise lancet output mechanism 5 (with reference to Figure 14 A and Figure 14 B) is that example is illustrated, but, also can form part that is equivalent to second parts and the part that is equivalent to extrude parts by parts.
