Abstract
The invention discloses a blood sampler with adjustable puncture depth, which mainly comprises a puncture depth adjusting mechanism, a blood sampling needle ejecting and auto-retracting mechanism and a blood sampling needle detaching mechanism. An adjusting ring of the puncture depth adjusting mechanism can be rotated to adjust puncture depth of a blood sampling needle into skin, so that injury of a person under blood sampling due to sufficient puncture depth or too deep puncture is avoided. Ejecting and retracting of the blood sampling needle are controlled by two compression springs of the blood sampling needle ejecting and auto-retracting mechanism, including an ejecting spring and a core pin retracting spring which respectively are mounted at the rear end of a core pin, and the ejecting spring and the core pin retracting spring are isolated by a slider. When blood sampling is complete once and the blood sampling needle needs to be changed, the blood sampling needle can be ejected out by unscrewing a sampler cap and pushing a slide rod forward, fingers can be protected from being torn by the needle tip, and safety and reliability are achieved. The blood sampler is simple and compact in structure, convenient in use, safe, hygienic, suitable for blood sampling places for blood test, and capable of effectively preventing cross infection.

Further, also be provided with projection 23 on described slide block 16, described projection 23 is positioned at a detent 19 that is arranged on the described hollow shaft of a writing brush.
Preferably, be provided with pointer 9 on described adjusting ring 2, the outside drafting of the hollow pen container in corresponding described pointer 9 the place aheads pierced through deep calibration 8.
Introduce in detail the using method of the present embodiment below in conjunction with the structure of this enforcement, the thrusting the adjustable blood collecting pen of the degree of depth and can be divided into three major parts according to difference in functionality of the present embodiment:
Depth adjusting mechanism is thrust in first.This mechanism adopts the helical guideway form, and will rotatablely move converts rectilinear motion to.Limited location snap ring 11, upper and lower pen container 3,4, and adjusting ring 2 is all coaxial, purpose is that the thorn that the restriction by the distance that travels forward of 11 pairs of dress punch blocks 12 of limited location snap ring limits blood taking needle 10 goes out the degree of depth.Adjusting slider 24 can be in upper and lower pen container 3,4 line slideway 18 freely-movables, also can be in the interior motion of helical guideway 25 of adjusting ring 2.Rotation adjusting ring 2, namely inner helical guideway 25 motions drive the motion of adjusting slider 24, because with tangent plane, the face of cylinder on X and two degree of freedom of Y are arranged, with respect to upper and lower pen container 3, line slideway 18 on 4 has one degree of freedom to be limited, adjusting slider 24 meetings are moved along the line slideway 18 on upper and lower pen container 3,4.Adjusting slider 24 can seesaw by drive limited location snap ring 11 together, and the displacement forward that fills punch block 12 is realized barrier effect, can realize regulating the degree of depth that blood taking needle 10 thrusts skin.Its depth value can be pointed according to pointer 9 on adjusting ring 2 the hollow pen container on the deep calibration 8 that thrusts read.
Second portion, blood taking needle emission and automatic resetting mechanism.This mechanism is mainly by firing button 5, and core bar return spring 15 is launched spring 17 compositions such as grade.Blood taking needle 10 thrusts after the degree of depth is determined, promote backward push-pull bar 26, push-pull bar 26 drives core bar 14, dress punch block 12, and 10 1 of blood taking needles move backward, until the briar tooth bullet of grab 20 advances the face of keeping out of spill baffle 29, meanwhile, firing button 5 is outwards ejected a segment distance by briar tooth, unclamps push-pull bar 26.
The effect of slide block 16 is to separate core bar return spring 15 and emission spring 17, and slide block 16 is threaded connection and is fixed on core bar 14.Slide block has projection 23 in both sides Shang Xia 16, and the detent 19 in projection 23 and hollow pen container matches, thereby slide block 16 and core bar 14 are circumferentially located, and can move around on hollow pen container axial direction.At this moment, core bar return spring 15 is decontroled, the power that follows the string, and emission spring 17 is compressed, ready to this blood collecting pen blood sampling Job readiness.
The cap for brush 1 front end of blood collecting pen is touched skin, and the power of being adjacent to is suitable, presses firing button 5, makes briar tooth break away from the face of keeping out of spill baffle.Elastic force due to 17 storages of emission spring, emission spring 17 promotes core bar 14 and travels forward fast, blood taking needle 10 stabs skin, simultaneously also cause core bar return spring 15 compressed, after being compressed to a certain degree, 15 bounce-backs of core bar return spring make core bar 14 and blood taking needle 10 returns, and two springs are got back to original state.
Third part, the blood taking needle disassembly mechanism.This mechanism mainly comprises push-pull bar 6, push-pull bar return spring 13 etc.After blood collection procedure is completed, blood taking needle 10 need to be unloaded.Back out the cap for brush 1, due to the diameter of the push-pull bar 26 front ends minimum-value aperture less than dress punch block 12, promote forward push-pull bar 26, can eject blood taking needle 10 forward, avoid with finger directly touch with the blood taking needle 10 of blood, prevent from being pricked.Then unclamp push-pull bar 26, due to the effect of push-pull bar return spring 13, push-pull bar 26 is got back to again original position.
The above is only the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
