Description

Blood drawing protective device

Technical field

It is especially a kind of to be inserted into for just exhausting the bloodletting needle of blood the utility model is related to manufacture technology field of medical appliance The device of operator is protected during test tube.

Background technology

At present, medical staff is drawn blood for the general arm blood vessel that patient is inserted into using bloodletting needle of patient's blood drawing, when When blood drawing amount is enough, medical staff needs that the blood just extracted out is identified and stored by bloodletting needle injecting tube, and bloodletting needle is being inserted When entering to carry the test tube of corking, since test tube mouth is smaller, blood drawing syringe needle is not easy to be aligned, and needs with certain dynamics ability By the corking of bloodletting needle insertion test tube, if bloodletting needle is not perpendicular to the insertion of corking surface, blood drawing syringe needle is easily sliped off and pierced The hand of test tube is held to operator, not only influences work efficiency, it is often more important that be easy to cause the injury to medical worker, medical matters " exposure " of personnel's limbs be easy to cause more serious infection and the infection of infectious disease, and what medical system was put into effect various anti-exposure arranges Shi Jun cannot efficiently solve this problem, thus need to consider to start with to the improvement of medical apparatus, " sudden and violent fundamentally to solve Dew " problem.

The content of the invention

Problem to be solved in the utility model is to provide a kind of blood drawing protective device, when being inserted into test tube to solve bloodletting needle Injury easily is generated to operator, and the problem of work efficiency is low.

To solve the above-mentioned problems, the technical solution of the utility model is：This blood drawing protective device includes under middle concave In the guide cone of inverted cone, the cone lower part of the guide cone, which is equipped with the centre extended downwardly, the guide part of through hole, described Guide cone has one for being inserted into the circular cover body of test tube openend, and the guide part of the guide cone is inserted into the cover body, The cover body is equipped with the slot for the insertion of test tube openend in the guide cone guide part lower end, logical in the guide cone guide part Hole is connected with the slot of the cover body；Spiral salient is equipped in the slot of the cover body, the protrusion is raised for cone, the protrusion Along groove face normal to slot inner end tilt 26 °~29 °, it is described protrusion busbar and axis angle in the range of 4 °~6 °；The cover Body is concavely formed the recess of operation gripping with the position that the guide cone guide part is connected in it, the recess with it is described The lower surface arc of cover body is excessive；The guide cone is colored transparent resin guide cone, the guide part and other parts Color is different, and the cover body is translucent Cowhells rubber cover body.

In above-mentioned technical proposal, more specifically scheme can be：The angle of the guide cone busbar and axis 75 °~ In the range of 83 °, the cone bottom surface outer diameter of described guide cone the top is more than the maximum outer diameter of the cover body, the minimum of the cover body Locate outer diameter in the range of 4.5 millimeters~8 millimeters.

By adopting the above-described technical solution, the utility model has the advantages that compared with prior art：

This blood drawing protective device has the resin guide cone of hardness that syringe needle of drawing blood is imported to the through hole among cone using one, makes Syringe needle, which pierces angle accurately and will not slip, stabs operator, and cover body can be packed into and clamp test tube, and blood drawing syringe needle is facilitated to be pierced into The corking of test tube, the spiral salient of special shape in slot, cuvette cartridge is fashionable to rotate an angle into cover body, and test tube can be made light Pine is transferred to, while bends convex top, then test tube is outwards gently pulled out, and makes all protrusion bendings and curvature increases, with examination Pipe forms larger frictional force, to clamp test tube, test tube is made to withstand the power that blood drawing syringe needle pierces through；Test tube is pulled out conversely, working as When going out, first make raised relaxation, then outwards rotation gently to the in vivo power of cover to one, test tube；Cover body and guide cone are formed The shape of handstand cup can not only facilitate gripping test tube, but also the hand that guide cone can be allowed to block operator, avoid the injury of syringe needle； Guide cone and cover body can allow entire bloodletting needle to be inserted into and blood transmittance process are all high-visible all using transparent material, side Just control, avoid occurring mishap when can't see process, the color of the guide part of guide cone is again different from other parts, plays target The effect of the heart makes operator visually easily can successfully be aligned.

Specific embodiment

The utility model embodiment is described in further detail below in conjunction with the accompanying drawings：

This blood drawing protective device as shown in Figures 1 to 4, it includes under middle concave in the guide cone 4 of inverted cone, leads The centre extended downwardly is equipped with to the cone lower part of cone 4 the guide part 4-1 of through hole 5, the resin guide cone for having hardness using one Syringe needle of drawing blood is imported into the through hole among cone, makes syringe needle thorn angle accurate and will not slip to stab operator.Under guide cone 4 Equipped with one for being inserted into the circular cover body 1 of 6 openend of test tube, the guide part 4-1 insertion cover bodies 1 of guide cone 4, cover body 1 is in guiding It bores guide part 4-1 lower ends and is equipped with slot 2 for the insertion of 6 openend of test tube, the slot of through hole 5 and cover body 1 in guide cone guide part 4-1 2 connections；Spiral salient 3 is equipped in the slot 2 of cover body 1, protrusion 3 is cone protrusion, and protrusion 3 is inclined along 2 face normal of slot to slot inner end Angle b=5 ° of rake angle a=28 °, raised 3 busbares and axis；Cover body 1 can be packed into and clamp test tube 6, facilitate blood drawing syringe needle The corking of test tube 6 is pierced into, the spiral salient of special shape in slot 2 rotates an angle into cover body when test tube 6 is packed into, can be with Test tube is made easily to be packed into and extract, and there are enough clamping forces to make clamping test tube when syringe needle of drawing blood is pierced into the corking of test tube 6.

Cover body 1 is concavely formed the recess 1-1 of operation gripping with the guide cone guide part 4-1 positions being connected in it, recessed Excessive into portion 1-1 and the lower surface arc of cover body 1, the person of being conveniently operated holds；Angle c=77 ° of 4 busbar of guide cone and axis, 4 the top of guide cone cone bottom surface outer diameter be more than cover body 1 maximum outer diameter, cover body 1 minimum at outside diameter d=5.5 millimeter, lead It is transparent resin guide cone to cone 4, cover body 1 is translucent Cowhells rubber cover body.Cover body 1 and guide cone 4 form handstand cup Shape can not only facilitate gripping test tube, but also the hand that guide cone can be allowed to block operator, avoid the injury of syringe needle；Guide cone 4 and cover Body 1 all using transparent material, can allow entire bloodletting needle to be inserted into and blood transmittance process is all high-visible, facilitate control, keep away Exempting from occur mishap when can't see process, the guide part 4-1 of guide cone is black, different from the green of 4 other parts of guide cone, Guide part, using striking contrast color, makes guide part play the role of target center, operator is made visually can with other parts Easily successfully it is aligned.

In use, rotating an angle when test tube 6 is packed into cover body 1, test tube can be made easily to be transferred to, while make protrusion 3 top curveds, then test tube 6 is outwards gently pulled out, make all bendings of protrusion 3 and curvature increases, larger rub is formed with test tube 6 Power is wiped, to clamp test tube, test tube is made to withstand the power that blood drawing syringe needle pierces through；Conversely, when test tube 6 is extracted, first to test tube 6 The one gently power into cover body 1 makes protrusion 3 relax, then outside Spin tubes 6 are easily taken out.
