First, with reference to Fig. 3 to Fig. 7, the composition of detailed description front unit F.

If with reference to Fig. 3, the front unit F include formed by means of double-material injection-molding front tip 10, can be discretely It is incorporated into the nut portions 30 of the rear end of front tip 10.

If with reference to Fig. 4 and Fig. 6 b, the front tip 10 is made by double-material injection-molding, in an injection mold, mutually Different component is shaped to single product by 2 injection steps.

1 injection article 10-1 shows the multiple numbers for being needled into depth for stepping as shown in figure 4, possessing on the outer periphery Raised 10a.Multiple number protrusion 10a and 1 injection article 10-1 are integrally formed, along the periphery of 1 injection article 10-1, by advance What is set is alternatively arranged into a row.On the other hand, preferably described 1 injection article 10-1 is with the POM with smooth property (Polyoxymethylene, polyoxyethylene methylene) resin is formed, can swimmingly to be rotated when being incorporated into nut portions 30.

It can be inserted separately in inside for the front end 34 of nut portions 30 in addition, 1 injection article 10-1 is formed with Cylindrical rib 20.The cylindrical rib 20 is formed with variform a pair as shown in Fig. 6 a and Fig. 6 b, in the inside of cylindrical rib 20 Internal diameter protrusion 21a, 21b combines so as to the front end 34 of nut portions 30.Variform a pair of internal diameter protrusion 21a, 21b configuration In opposite both sides (180 degree).At this point, nut portions 30 in the outside of front end 34 as shown in fig. 7, be formed with for cylindrical rib 20 The spiral slot 30a and multiple locating slot 30b that internal diameter protrusion 21a, 21b fastens respectively.

2 injection article 10-2 are as shown in figure 5, with the big little makings of than 1 time injection article 10-1 size bigger, so as to wrap Wrap up in 1 injection article 10-1, and be formed with the multiple number protrusion 10a possessed for 1 injection article 10-1 be inserted into respectively it is multiple Digit punch 10b.At this point, 2 injection article 10-2 are different from 1 injection article 10-1, with ABS (Acrylonitrile Butadiene Styrene, acronitrile-butadiene-styrene) resin making.If this exemplified by forming other components of 1 shape of hemostix, leads to It crosses using the 70 identical material of outer sleeve (outer sleeve) with backward units R, same texture can be assigned to products appearance.

As described above, 1 time and 2 injection articles 10-1,10-2 by double-material injection-molding process, are integrally formed as shown in Figure 6 a, Form front tip 10.Therefore, multiple number protrusion 10a that 1 injection article 10-1 possesses are inserted in the shape on 2 injection article 10-2 Into multiple digit punch 10b, so as to which number protrusion 10a is exposed to the outside of 2 injection article 10-2, therefore, user naturally By the multiple number protrusion 10a and can easily interpretation number.

Wherein, in order to help the interpretation of the number, if the color of resin selection color of 1 injection article and 2 injection articles The resin of coloured silk comparison, then the digital 10a shown on 10 surface of front tip can brightly interpretation.

It therefore, can be by the use of as single unit as shown in figure 3, as the front tip 10 and nut portions 30 combine Front unit F is disposed.As described above, the front tip 10 of the present invention is different previous, it is convenient to omit as other composition Inside tip.

Therefore, the present invention have component minimizing effect, and eliminate component assembling caused by assembling tolerance, provide it is set, Depth accurately is needled into, moreover, each shelves Digital ID for being needled into depth of the external printing in front tip, without other Printing process can embody in injection step, thus will not be erased in use, can specifically identify and be needled into depth Each gear number word of degree, so that user, which easily can adjust and grasp, is needled into depth.

On the other hand, it is inserted in whenever using the blood taking needle 200 as disposable unit (with reference to Fig. 2) backward units R's During clamping part 82 (with reference to Fig. 2) for the cylindrical shape that carrier 80 is equipped with, the front unit F is torn open repeatedly on backward units R Dress.If at this point, with reference to Fig. 7, the nut portions 30 of the front unit F forming position fixed lobe 32 on inner peripheral surface is single at rear 40 front of fixing pipe of first R, forms the position fixing groove 40a (references fastened for the position fixed lobe 32 of the nut portions 30 Figure 10), so as to which when front unit F is incorporated into backward units R, the negative thread 33 of the internal diameter rear end portion of the nut portions 30 is borrowed Help substantially fasten assembling half-turn or so along the oblique line protrusion 49a (with reference to Fig. 8 a) of the front end periphery formation of fixing pipe 40, Always commitment positions are stopped at, thus blood taking needle 200 is linked to the commitment positions always of clamping part 82.

It therefore, also can stop position different from the past even if front unit F and the dismounting operation of backward units R is repeated Different situation when assembling binding strength is put, being needled into depth can remain set.Therefore, the present invention can be prevented fundamentally The following phenomenon of previous hemostix, i.e. if user's forced locking front tip 10, the skin piercing depth of pin 201 is elongated, Blood pours out, if weaker lock front tip 10, narrow 201 skin be pierced into depth shorten, blood is gushed out slightly.

The front unit F can be adjusted the pin from 200 front end of blood taking needle protrusion certain length by multi gear (for example, 7 grades) 201 are needled into depth.In the following, illustrate the structure for being needled into depth for adjusting the pin 201 of blood taking needle 200.

The front end 34 of the nut portions 30 is formed in staggered floor so that has the outer diameter less than rear end portion, to supply Front tip 10 is stated to link.The front end 34 of nut portions 30 is formed with spiral slot 30a (with reference to Fig. 7) substantially across 180 degree, together When, along the periphery of front end 34, totally 7 locating slot 30b are formed with by substantially 25 degree intervals in axial direction.

Internal diameter protrusion 21a, 21b formed respectively in the cylindrical rib 20 of front tip 10 is fastened on the spiral shell of the nut portions 30 Revolve shape slot 30a and locating slot 30b.At this point, some internal diameter protrusion 21a in a pair of of internal diameter protrusion 21a, 21b is with front tip 10 rotation and along spiral slot 30a slide, moved back and forth, remaining internal diameter protrusion 21b is inserted in multiple locating slot 30b Some.Therefore, front tip 10 is advanced or is retreated on the basis of nut portions 30, at the same time, can be set exactly For some in pre-set 7 grades.

At this point, a pair of of internal diameter protrusion 21a, 21b formed in the cylindrical rib 20 of front tip 10 with respectively in interference fit with The mode of spiral slot 30a and locating slot 30b are assembled in nut portions 30, the both sides shape around a pair of of internal diameter protrusion 21a, 21b Into cutting section 23a, 23b, so that a pair of of internal diameter protrusion 21a, 21b has elasticity so that easily rotated when front tip 10 rotates It slides.

The front unit F so formed is in the state of backward units R is assembled in, if for metering needle piercing depth Front tip 10 is made to be rotated to a direction or its opposite direction, then it is a certain in a pair of of internal diameter protrusion 21a, 21b of cylindrical rib 20 A internal diameter protrusion 21a is advanced or is retreated while the spiral slot 30a along nut portions 30 is rotated to oblique line directions, Distance, which is adjusted, between the front end of front tip 10 and the front end of the pin 201 of blood taking needle 200 must become remote or become near, so as to 1 as 7 In shelves, the skin of pin 201 is adjusted to required depth with being pierced into appropriate depth.

On the other hand, the cylindrical rib 20 of front tip 10 in rear end as shown in Figure 6 a, be formed with by 180 degree angle formed one To the 1st inclined ribs 22.At this point, nut portions 30 are as shown in figure 3, be formed with the 2nd inclined ribs 30c of a pair, in the circle front tip 10 When cylinder rib 20 is incorporated into nut portions 30, the pair of 2nd inclined ribs 30c is corresponding with the 1st inclined ribs 22 of a pair of front tip 10.

At this point, formed must be longer than another for some in the pair of 1st inclined ribs 22.Therefore, if making paracone End 10 is rotated to a direction, then a pair 2nd inclined ribs 30c of the 1st inclined ribs 22 of a pair of cylindrical rib 20 along nut portions 30 Rise, front tip 10 protrudes into front, if on the contrary, make 10 counter-rotating of front tip, a pair of 1st inclined ribs 22 are along a pair 2nd inclined ribs 30c declines, meanwhile, front tip 10 retreats.

At this point, when current tip 10 sets back, the 1st and the 2nd inclined ribs 22 of a pair of cylindrical rib 20 and nut portions 30, The interlaced occlusion in end of 30c so that cylindrical rib 20 can not further rotate.Therefore, even if user is with the reverse rotation of strength Then cylindrical rib 20 is made to cross original position, a pair of 1st and the 2nd inclined ribs 22, the interlaced occlusion in the end of 30c prevent front tip 10 counter-rotating, so as to prevent that front unit F is damaged or decomposes.

In addition, front tip 10 rotates in the state of nut portions 30 are inserted in, so as to adjust the protrusion distance of front tip 10 Degree at this point, a pair of 1st and the 2nd inclined ribs 22,30c become the state of mutual linear contact, thus prevents from being applied to front tip 10 arbitrary external impact and thus caused pressing, so as to realize accurate pin depth adjustment.

Referring to Fig. 8 to Figure 18, the composition of the backward units R is described in detail.

In fig. 8, it is illustrated that the backward units F of front unit F discrete state.

It is therefore, of the invention without once being applied in previous hemostix as the ultrasonic fusing operation in addition assembling equipment, Just the firm assembling between component can be realized.

On the other hand, there is inside end 48 (with reference to Figure 16) in the end of the guide groove 47 of fixing pipe 40, if carrier 80 rearward movements both more than set a distance, were then mounted on inside end 48.Therefore, when in order to load carrier 80 and rear tip 90 When pulling back in the past so that user arbitrarily cannot unlimitedly pull back, and be pulled so as to eliminate when in order to load Filling operation the problem of causing a part of component damaged or can not operating.

Button 50 is installed on outer sleeve 70, be arranged at 44 corresponding position of ratchet holes, so as to emit adopting for filling Blood pin 200.Button 50 is put into inside outer sleeve 70, and a pair of of fixed lobe 50a, the 50b formed on button 50 is directed at dress A pair of of fixing groove 74a, 74b assigned in outer sleeve 70.At this point, fin 70c is formed at the edge of the button hole 70b of outer sleeve 70, So that when by lower button 50, when user is made to perceive by lower button 50, carrier 80 could emit, can prevent by Button 50 is excessively easily pressed or occurs maloperation.

If with reference to Fig. 9, displacer 60 can be located at the position of the button 50 installed on outer sleeve 70 or form 55 Substantially 90 degree directions, so that user can be operated using the thumb for the hand for holding hemostix 1.

The displacer 60 includes being exposed to the handle portion 61 in 70 outside of outer sleeve, extends what is formed in 61 one side of handle portion Pressurization part 62.If handle portion 61 is made to be moved along the direction of principal axis of hemostix 1, pressurization part 62 ifs, passes through together with handle portion 61 The square breakthrough part 86 of logical carrier 80 is carried forward advance movement.

On the other hand, in order to replace used blood taking needle 200, first, what is threadably combined with fixing pipe 40 Nut portions 30 are separated from fixing pipe 40, and after exposing used blood taking needle 200, handle shank 61 pushes safe hemostix 1 to Front, pressurization part 62 release blood taking needle 200 through the square breakthrough part 86 of carrier 80, make blood taking needle 200 from carrier 80 Separation.

The displacer 60 is formed with track groove 60b, the track 70a of the outer sleeve 70 at both ends and is inserted in the track Slot 60b.Rear portion therefore, it is possible to prevent displacer 60 cross pressing and it is damaged.

The displacer 60 is formed with multiple raised 65 in both sides, when pushing away displacer 60, in the track two of outer sleeve 70 It holds the raised 70e (with reference to Figure 11) formed and multiple raised 65 is interfered what described 60 liang of end side surfaces of displacer formed a line And the sense of touch vibrated, thus make user's cognition to displacer 60 in operating (movement).

If with reference to Figure 11, the front and back of outer sleeve 70 open, and partition rib 71 is formed in center of inside.In the partition Cross bore 72 is formed on rib 71.

The outer sleeve 70 is as shown in figure 16, on the basis of separating rib 71, inside the front of outer sleeve 70 and in rear Portion is each configured with multiple components.That is, on the basis of separating rib 71, inside the front of outer sleeve 70, the 3rd spring S3 of receiving, 80 and the 1st spring S1 of safety cap 75, fixing pipe 40 and carrier.

In addition, on the basis of the partition rib 71 of outer sleeve 70, in 70 rear inner part of outer sleeve, the 2nd spring S2 and interior is accommodated Sleeve 95, end ring 110, rear tip 90.

In addition, in the exterior lateral sides of the outer sleeve 70, it is respectively formed and is useful for accommodating button 50, form 55 and displacer The 60 button hole 70b, form hole 70d, displacer cutting section 70i as cutting section combines rear tip in 70 rear end of outer sleeve 90。

If with reference to Figure 12, safety cap 75 is formed with surrounding the cylindrical shape of " D " font of fixing pipe 40, is formed in inside Guiding rib 76.

When safety cap 75 is assembled in 70 inside of outer sleeve, after button 50 is first assembled in 70 front inside of outer sleeve, Safety cap 75 is inserted into, therefore, in order to prevent with reference to hole portion 78 and button rib 52 (with reference to Figure 13) interference, is formed and pacified by " D " font The combination hole portion 78 of full cap 75.

In addition, the inside guiding rib 76 of the safety cap 75 when the pin 201 of blood taking needle 200 exposes, for safety, is such as schemed Shown in 18, by the flange 83 for holding carrier 80 so that the single armed hook 42 for the fixing pipe 40 that carrier 80 can not emit pressurizes (P1, with reference to Figure 18) bends towards the inside of 80 flange of carrier, 83 cutting section 83a so that carrier 80 can not move.

The safety cap 75 is respectively formed with：Bullport 77 is rearward moved when loading carrier 80, and can be with The occlusion of single armed hook 42 of fixing pipe 40 is held；With reference to hole portion 78, combined with the salient rib 45 of fixing pipe 40；Opening 79, with The guiding rib 46 of fixing pipe 40 combines.In addition, the safety cap 75 is formed with the raised 75a of small cylindrical shape at rear, with The 3rd spring S3 can be fixed.

If with reference to Figure 14 a and Figure 14 b, carrier 80 includes pawl 81, clamping part 82, flange 83, hook 84, square passes through Logical portion 86, multiple front guiding ribs 87 and rear cross rib 88.

Pawl 81 is equipped with cantilever form, and elasticity is incorporated into the pawl mounting part 44a so that the fixing end of pawl 81 81a is fixed on carrier 80, and the free end 81b of pawl 81 is towards 80 lateral direction of carrier, so as to the spine for the pipe 40 that is fastened Pawl mounting part 44a.

Clamping part 82 is formed in 80 front end of carrier, can discretely be combined for blood taking needle 200.The clamping part 82 is with circle Barrel shape is formed, and has elastic force, to be smoothed out the dismounting of blood taking needle 200, in addition, in the side of clamping part 82, with zigzag Shape is formed with side cut-away portion 82a and bottom surface cutting section 82b.At this point, previous hemostix there are the problem of be side cut-away portion It is formed with straight line, thus blood taking needle rib 203 is inserted into the side cut-away portion in a slanted state, therefore, when carrier 80 emits, hair The pin 201 of raw blood taking needle 200 can not pass through the mistake of the front aperture 11 of front tip 10.

But for the present invention, when blood taking needle 200 is made to be incorporated into clamping part 82, the side cut-away portion of clamping part 82 82a is cut as shown in Fig. 9 or Figure 14 a, b with zigzag shape, thus when blood taking needle 200 is inserted in clamping part 82, blood taking needle Rib 203 is not inserted into side cut-away portion 82a, but cause always with clamping part 82 it is coaxial on be inserted in clamping part 82, can Prevent the maloperation occurred in previous hemostix.

In addition, the clamping part 82 of carrier 80, as shown in Figure 14 a and Figure 14 b, along inner circumferential surface, setting has alternately formed Multiple grip rib 82c.Therefore, after blood taking needle 200 being inserted into clamping part 82, in order to which the pin 201 for making blood taking needle 200 exposes, torsion is worked as When subcontracting the protective cap 202 (with reference to Fig. 9) for enclosing pin 201 and being removed from pin 201, the blood taking needle rib 203 of blood taking needle 200 is multiple Grip rib 82c is interfered, and prevents blood taking needle 200 from skidding together with protective cap 202, so as to easily protective cap 202 from Pin 201 separates.

With reference to Figure 16 and Figure 20, flange 83 is formed in the substantial mid-portion of carrier 80, advance inside fixing pipe 40/ Retreat ground perforation fixing pipe 40.One end of the 1st spring S1 of 83 resilient support of flange.The 1st spring S1 is installed on carrying Between the flange 83 of frame 80 and the partition rib 71 of outer sleeve 70, the effect of performance is the 1st bullet when carrier 80 rearward moves After spring S1 is compressed, with the operation of button 50, compression moment releases and carrier 80 is emitted forwards.

Hook 84 is formed as shown in fig. 14b at the rear of carrier 80.At this point, the 2nd spring S2 is inserted in 95 He of inner sleeve Between end ring 110, hook 84 is linked to the end ring 110, combines the 2nd spring S2.Therefore, if in order to load carrier 80 And rear tip 90 being pulled to the rear of hemostix 1, then inner sleeve 95 compresses the 2nd spring S2, is held with what inner sleeve 95 moved together Carrier 80 rearward moves, and the free end 81b of the pawl of carrier 80 is fastened on the pawl mounting part 44a of fixing pipe 40, blood sampling Device 1 can be loaded with preparation state of taking a blood sample.

Square breakthrough part 86 is formed in 80 center of carrier, guided so that displacer as shown in Figure 14 a and Figure 14 b 60 pressurization part 62 is penetrated through and moved.

Multiple front guiding ribs 87 generally comprise cross shape, in order to keep the straight of straight movement when carrier 80 emits Into property, as illustrated in fig 17 a, it is inserted in respectively in 4 guide grooves 47 formed in fixing pipe 40.

On the other hand, it is (preferably aobvious to paint set color on surface by 1 guiding rib 87a in multiple front guiding ribs 87 Yellow or red of eye etc.).Therefore, when carrier 80 moves back and forth, i.e. as the state for not loading carrier 80, holding When carrier 80 moves forwards, any color is not shown by form 55, and as the state of the filling of carrier 80, in carrier 80 when rearward moving, and is moved back as carrier is after 80s, identify coloured guiding rib 87a by form 55 and external as it can be seen that So that user can utilize the color shown by form 55, easily grasp whether carrier 80 loads.

Rear cross rib 88 sets predetermined distance shape at the rear of the multiple front guiding rib 87, from front guiding rib 87 Into.As illustrated in fig. 17b, perforation is inserted in the cross bore that the partition rib 71 among outer sleeve 70 is formed to the rear cross rib 88 72, meanwhile, as shown in fig. 17 c, also perforation is inserted in the cross bore 98a of breakthrough part 98 before in inner sleeve 95, helps to carry The translatory movement of frame 70.

Therefore, when carrier 80 emits, in the front of backward units R, multiple leading by fixing pipe 40 of front guiding rib 87 Track slot 47 guides, in the centre of backward units R, rear cross rib 88 formed on the partition rib 71 among outer sleeve 70 ten Word hole 72 guides, and at the rear of backward units R, rear cross rib 88 is by the cross bore of breakthrough part 98 before in inner sleeve 95 98a is guided, and therefore, carrier 80 can not rock straight movement forwards.

As described above, when the carrier 80 advances transmitting by means of the elastic force of the 1st spring S1, in backward units R It is steadily guided at internal front, centre and rear 3, so as to which pin does not rock, to ensure that the state of rectilinear propagation is pierced into skin, Thus pain can be substantially reduced in blood sampling.Therefore, the shortcomings that present invention can be prevented when previous hemostix from using, i.e. The pin 201 of blood taking needle 200 does not have rectilinear propagation, and before with zigzag and then when being pierced into skin, because excavate skin the phenomenon that due to induces pain Bitterly.

If with reference to Fig. 9 and Figure 16, rear tip 90 is formed with engagement groove 91 in inner peripheral surface, and the engagement groove 91 can be discretely It is fastened on the hook protrusion 96 of inner sleeve 95.In addition, rear tip 90 surrounds inner sleeve 95, the 2nd spring S2 and end ring 110.

Rear tip 90 is fixedly connected in inner sleeve 95 so that can together start with inner sleeve 95.The rear tip 90 is held Carrier 80 pulls to 1 rear of hemostix so that filling carrier 80.As described above, when rear tip 90 is pulled to rear, carrier 80 81 fixing end 81b of pawl holdings are mounted on the state of the pawl mounting part 44a of fixing pipe 40, and the 1st spring S1 is compressed.

If in this state by lower button 50, the pawl 81 of carrier 80 departs from from the ratchet holes 44 of fixing pipe 40, By means of the elastic force of the 1st spring S1,80 moment of carrier advances together with blood taking needle 200.Therefore, the pin 201 of blood taking needle 200 is logical After crossing the pin through hole 11a of front tip 10, skin is pierced into, a small amount of business can be made to be discharged to outside skin.

Inner sleeve 95 has the diameter less than outer sleeve 70, to be inserted in 71 rear end portion of partition rib of outer sleeve 70 Side.

The inner sleeve 95 is externally formed with the hook protrusion 96 linked with the engagement groove of rear tip 90 91.It is moreover, described Inner sleeve 95 is formed with guide hump rib 97 in the position of adjacent hook protrusion 96.Guide hump rib 97 can be slidably coupled to rear The sliding groove 92 that the inside at tip 90 is formed.Therefore, inner sleeve 95 makes what carrier 80 loaded with being pulled to 1 rear of hemostix Rear tip 90 is fixedly connected.

In addition, inner sleeve 95 is combined with the end ring 110 mounted for the hook 84 formed at carrier end after 80s in inside.Institute It states end ring 110 and is formed with step, the 2nd spring S2 is installed between the front end of inner sleeve 95.The 2nd spring S2 is being beaten The effect for absorbing and impacting and blood taking needle 200 being made slightly rearward to return is played after hitting blood taking needle 200.

Furthermore, inner sleeve 95 is equipped with multiple noise prevention protrusions 98 in front end 99, inhibits filling carrier 80 When component between the noise that occurs, the fear that person of blood collecting feels due to the noise can be eliminated.

Furthermore, inner sleeve 95 is formed with the cross combined for the perforation of cross rib 88 of carrier 80 in front end 99 Hole 98a.Therefore, the cross bore 72 of outer sleeve 70 and the cross bore of inner sleeve 95 that carrier 80 is inserted into simultaneously for cross rib 88 98a is guided, thus in 30 translatory movement of carrier, prevents that carrier side after 80s from rocking, it can be ensured that carrier 80 has The straight performance of reliability.

Further, it enables it can selectively be checked on 95 surface of inner slide with rearward pulling and operating rear tip 90 The production of articles lot number of mark, so as to track production of articles.

In addition, if with reference to Figure 15, the inner sleeve 95 utilizes laser printing product batch number L on surface so that not because anti- It operates and is wiped free of again.At this point, being covered when inner sleeve 95 is flat by outer sleeve 70, product batch number L is not revealed in outside, if backward Fang Ladong rear tips 90 are then exposed to outside and can confirm naturally, if rear tip 90 sets back, product batch number L is hidden It is hidden in outer sleeve 70.

On the other hand, hemostix 1 is as shown in figure 18, in the state of the separation of front unit F, even if blood taking needle 200 is inserted Enter the clamping part 82 of carrier 80, hold rear tip 90 and move 1 rear of hemostix to, can not also install carrier 80 additional.That is, exist Under the state, the guiding rib 76 of safety cap 75 keeps pressurizeing to the single armed hook 42 of fixing pipe 40 state of P1, thus flange 83 Cutting section 83a is held by single armed hook 42.Therefore, carrier 80 is limited by single armed hook 42 to the movement of filling direction.

Therefore, (that is, front unit F is from the separated shapes of backward units R for the state jeopardously exposed in the pin 201 of blood taking needle State) under, user can not load and emit carrier 80, thus can safely use hemostix 1.

On the other hand, as shown in figure 19, if front unit F is installed in backward units R, the rear side of nut portions 30 Face 31 pressurize (P2, with reference to Figure 19) promote the front end side 63 of displacer 60.Therefore, displacer 60 is the peace in rear side 64 Full cap 75 is released to pusher so as to once be applied to the plus-pressure of the guiding rib 76 of the single armed hook 42 of fixing pipe 40.Therefore, single armed hook 42 are moved to original position, discharge the flange 83 of the carrier held originally 80.

Therefore, front unit F in the state of backward units R is installed in by hemostix 1 of the invention, with a holding Firmly, moved to after rear loaded, can be emitted by lower button with another hand handle rear tip 90.
