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.

具体实施方式 detailed description

[0019]下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述。 [0019] The present invention in conjunction with the following drawings in the embodiments, the technical solutions in the embodiments of the present invention will be clearly and completely described.

[0020]如图1-图5,本发明提出了一种一次性使用安全采血器,包括壳体1、驱动触发装置,所述壳体I下部转动连接有扭簧2;所述壳体I上部水平设置有壳口3,所述驱动触发装置从所述壳口3伸于所述壳体I内;所述扭簧2—端水平设置有采血针4,且位于所述驱动触发装置下部,所述采血针4头部指向所述壳口3;其中,所述驱动触发装置包括触发本体6,所述触发本体6中心设有激发槽7,所述扭簧2上端伸入所述激发槽7内;所述触发本体一端设有激发口挡护8,另一端设有击发推挡9,所述击发推挡9侧边设有斜面10。 [0020] Figures 1 to 5, the present invention provides a disposable blood collection safety device, comprising a housing, a trigger drive means, said housing rotatably connected to a lower portion of torsion spring I 2; I said housing an upper horizontal opening 3 is provided with a housing, said trigger driving means in the housing extending from said housing inlet 3 I; 2- end of the torsion spring is provided with a blood collection needle 4 horizontally, and a lower portion located in said trigger driving means , the lancet 4 of the head 3 toward said housing opening; wherein said trigger means includes a trigger drive body 6, the central body 6 is provided with excitation trigger groove 7, the torsion spring 2 extends into the upper end of the excitation the groove 7; body provided at one end of the trigger port excitation fence 8, 9 and the other end is provided with a firing block shot, the firing Tuidang 9 side provided with a bevel 10.

[0021 ]该驱动触发装置可在该壳体I内直线运动,并可驱动扭簧2活动端位移圆周运动,并在斜面位置释放扭簧2发射,带动采血针4运动凸出采血器的壳体I一端开口,壳口3和采血针4交汇点为直角。 [0021] The housing means can drive trigger linear movement within the housing I, which can drive two movable end of the torsion spring circumferential displacement movement, the torsion spring is released and the bevel position 2 emission, the lancet drive 4 projecting motion of the blood withdrawal device I body open at one end, the housing inlet 3 and the blood collection needle 4 is a right angle intersection.

[0022]本发明的工作方式是:如图1所示,处于自然状态无蓄能状态时,驱动触发装置的触发本体6伸于壳体I内,并且激发口护挡卡于壳口3处,将整个壳口3遮挡,此时,壳口3内的采血针4被激发口护挡遮挡,对采血针4起针尖保护作用,防止污染或误操作; [0022] The mode of operation of the present invention is: 1, when in a natural state without energy storage state, the driving body of the device to trigger the trigger extends in the housing 6 I, and excites the shield of the card at the mouth opening 3 of the housing , the entire shell port 3 blocked, this time, the lancet within the housing opening 34 the shield of blocking ports are excited, the protective effect of the blood collection needle 4 from the tip-to prevent contamination or misuse;

[0023]使用时的工作方式为:如图2、图3、图4,通过外力拉动驱动触发装置,直至拉至扭簧2的前部,再旋转90°,使得激发口护挡处于水平状态,转动后,击发推挡9压于扭簧2的端部,此处触发本体6上设有与所述限位杆5配合的卡块11,卡块11转动至限位杆5,即不可转动,此时扭簧2上端压于击发推挡9上,再向壳体I内推进触发本体6,压动扭簧2,扭簧2沿着卡簧柱12转动,扭簧2储蓄了部分能量,触发本体6继续推进时,扭簧2的端部逐渐沿着击发推挡9下部的斜面10滑动,逐渐释放扭簧2,脱离激发槽,并沿着触发本体外侧壁活动,带动采血针4的发射,由于扭簧2积蓄的较大的力,采血针4会发射至壳口3,并略微伸出壳口3,壳口3对准采血皮肤处,即可刺破皮肤; [0023] When the work is used: 2, 3, 4, triggered by an external force pulls the drive means to pull up the front portion of the torsion spring 2, and then rotating 90 °, such that the shield of the excitation port in the horizontal state after the rotation, the firing Tuidang 9 is pressed to the end portion of the torsion spring 2, where the trigger lever 5 is provided with the stopper block 11 with the card, the card 11 is rotated to block the retainer lever 5, that is, not on the body 6 rotation, the torsion spring case 2 pressed against the upper end of the firing Tuidang 9, again to promote the triggering of the body within the housing I 6, the pressed 2 torsion, torsion 2 circlip rotated post 12, a torsion spring portion savings 2 energy, trigger body 6 continues to advance, the end portion of the torsion spring 2 is gradually inclined surface 10 is slid along the firing Tuidang lower portion 9, the torsion spring 2 is gradually released, from the excitation channel, and along the side walls in vitro activity of the present trigger, the lancet drive 4 is emitted, due to the large force of the torsion spring 2 accumulated, blood collection needle 4 will transmit port 3 to the shell, the shell and slightly projecting port 3, aligned with housing opening 3 of blood at the skin, can puncture the skin;

[0024] 其中,所述采血针4释放后垂直指向所述壳口所在平面,采血针4垂直射出,垂直度越高能够保证,采血时人的疼痛感越低。 [0024] wherein, upon release the blood collection needle 4 directed perpendicularly to the plane of the housing opening is located, the blood collection needle 4 is emitted vertically, to ensure that the higher the degree of vertical, while the lower human blood pain.

[0025]此时的触发本体6已经完全伸入壳体I内,由于所述激发口挡护8为矩形,所述激发口挡护8的宽度与所述壳口3的高度相同,并且可以伸入至壳口3内,如图5,所述壳口3设有用于限定驱动触发装置的倒扣,通过倒扣将触发本体6限位,无法再退出,即可实现驱动释放装置的锁定,限制采血器被重复使用。 [0025] At this time, the trigger body 6 has been completely extended into housing I, since the excitation port 8 is rectangular fence, the fence excitation port 8 at the same height and the width of the opening 3 of the housing, and may be extend into the port casing 3, as shown in FIG 5, the housing 3 is provided with a port defining triggering drive device upside down, by the trigger flip stop body 6, can no longer exit, can achieve lock drive release device restricting blood is reused.

[0026]优选的,所述壳体I下部设有卡簧柱12,侧壁设有定位槽13,所述扭簧2套于所述卡簧柱12内,且未安装采血针4的一端部卡于所述定位槽13内,保证扭簧2压缩储能。 [0026] Preferably, the housing is provided with a lower I circlip column 12, sidewall 13 is provided with positioning slots, two sets of the torsion spring circlip in the column 12, one end of the lancet 4 is not installed in the positioning portion in the card slot 13, to ensure that the torsion spring 2 compressed storage.

[0027]对实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。 [0027] Various modifications of the embodiment of the present professional skilled in the art will be apparent, and the generic principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention . 因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。 Accordingly, the present invention will not be limited to the embodiments shown herein but is to be accorded herein consistent with the principles and novel features disclosed widest scope.
