Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of syringe, particularly a kind of safety self-destructing syringe.
Background technology
Cause viral cross infection for fear of using antihygienic syringe, disposable syringe is widely used in medical field.Can only not use the technical measures that once and not are reused but common disposable syringe does not have, make secondary to occur free can the boring of the not really regular individual medical clinic of some medical institutions, particularly minority and use, even the phenomenon that is repeatedly used.For this reason, on push rod, be provided with the shackle member that engages with syringe when people design syringe,, make push-rod lock in syringe, can not reuse, thereby reach the purpose of self-destruction when the injection rear push-rod that finishes engages with syringe.But this class syringe at drawing liquid secondary piston front end not on zero line, therefore during drawing liquid uses, cause drawing liquid dosage nonstandard on the one hand, make that on the other hand the air in the syringe was residual not more when syringe used, it is more that the push rod head of this class syringe exceeds plug, when drawing liquid, can produce the difficult discharge of bubble at the plug top, especially as the syringe of this class low dose of insulin syringe, its bubble is discharged can be difficult, there is injection residual after this class injector to inject finishes in addition, can not reaches the standard of low-residual.
In view of the existence of more above-mentioned problems, people can make syringe needle be contracted in the injection tube and the self-destruction syringe of low-residual by improving structure, having designed.For example, Chinese patent discloses a kind of low-residual safe self-destructing injector [publication number is: CN101444649A], comprise a hollow barrel, one push rod that in syringe, slides, be installed in the plug of push rod front end, the front end of syringe is equipped with needle stand, needle stand is supported by supporting seat, the supporting seat inboard is provided with elastic card claw, the push rod front end is provided with the frustum that engages with elastic card claw after injection finishes, when not injecting at the bottom of the awl of described frustum with plug top butt, plug is a hollow type, push rod is provided with the block of pushing and pressing plug, plug is subjected to the counteracting force of injection generation and the thrust compressive deformation of block during injection, this moment the push rod front end frustum along axially the protracting of push rod, the injection back frustum that finishes can engage with elastic card claw.
But, the syringe of this class formation when work needle stand on the elastic card claw design unreasonable.In such scheme, because elastic card claw is arranged on the supporting seat inboard, when the injection rear push-rod that finishes might only retract supporting base in the injection tube, needle stand and syringe needle then are retained in the injection tube front end, and the staff can be by needle sting when handling these discarded syringes.Moreover, be arranged on the elastic card claw uniform distribution in the supporting seat and be positioned on the same working face, when being patient infusion with this syringe, in order to realize the low-residual in the operating process, the frustum of push rod front end is pushed in the supporting base engages with elastic card claw, the frustum of push rod front end will enter in the supporting base and with elastic card claw and engage moment in the process that pushes, and owing to the pressure that inputs to the patient changes suddenly, make the patient feel very pain during this period.
Summary of the invention
The objective of the invention is to have the problems referred to above, proposed a kind of reasonable in design and in operating process, can effectively alleviate the safety self-destructing syringe of patient's pain at existing technology.
Purpose of the present invention can realize by following technical proposal:
The safety self-destruction syringe, comprise injection tube, injection rod, rubber stopper and be needle holder cylindraceous, described rubber stopper is connected in the front portion of injection rod, above-mentioned needle holder is connected the front end inboard of described injection tube, it is characterized in that, the front portion of described injection rod has the bar head that passes rubber stopper and stretch out rubber stopper, described rod head end portion has keeper, described needle holder inwall is provided with convex body, the elasticity that described keeper can utilize keeper itself or described convex body when above-mentioned bar head is inserted in the needle holder by described convex body and make described keeper and described convex body between form interface arrangment, this interface arrangment has and prevents that described bar head from withdrawing from the effect of needle holder.
When the safety self-destruction syringe in use was not inserted in the needle holder as if the bar head, injection rod can move forward and backward in injection tube, realizes drawing liquid and injection.In the injection process, when the bar head is inserted in the needle holder, consider that this syringe can only once use, when keeper abuts on the convex body, medical personnel continue to say that injection rod promotes to injection direction, and this moment, keeper continued to move forward, keeper or convex body bending in the moving process.After keeper passed through convex body, the keeper or the convex body that bend under the effect of elastic force resetted, and the back keeper that resets is stopped that by convex body force keeper to be connected in the needle holder, people are very difficult things if want to make injection rod to withdraw from needle holder.The inboard interference fit of the outside of needle holder one end and the front end of injection tube, frictional force between the two is just greater than the pressure that produces in the injection process, but the power when in keeper snaps fit onto needle holder, needle holder being retracted, be arranged on like this in the injection process and the seepage phenomenon can not occur between the needle holder and injection tube, when the needs self-destruction, also needle holder can be withdrawn in the injection tube, in the time of in needle holder is pulled back to injection tube, injection rod is fractureed realize the purpose of self-destruction.
Keeper is for having spigot surface, and keeper can be shapes such as circular cone, round platform here, and the big end and the bar head of keeper are fixed together, when small end is used for by convex body the guiding and with convex body against.
In above-mentioned safety self-destructing syringe, when being described keeper rollback, described interface arrangment stopped by described convex body.
This interface arrangment is to realize clamping like this: when keeper under the elastic force effect by behind the convex body, because keeper or convex body need return to original state, cause keeper to be stopped by convex body after the recovery, thereby can't pass through convex body, keeper can only abut on the convex body during pulling push rod.In order to realize that keeper is blocked, then to the minimum range of needle holder axis, and convex body is to the minimum range of the needle holder axis radius greater than the bar head greater than convex body for the radius of keeper maximum cross section.
In above-mentioned safety self-destructing syringe, described convex body has several and has elasticity, all has an inclined-plane that tilts along the place ahead of needle holder on described each convex body.
The purpose of She Zhiing is like this, when keeper will pass through convex body, and the joint, inclined-plane of keeper and convex body, because convex body has elasticity, then the inclined-plane of convex body expands outwardly under the extruding of keeper, makes things convenient for passing through of keeper.When keeper when the convex body, convex body returns to original state under self elastic force, when this moment, keeper pushed convex body again, convex body then can not expand outwardly, convex body has stopped keeper thus, makes keeper by clamping.Convex body is set to several, has more effectively stoped convex body, makes self-destruction be more prone to realize.
In above-mentioned safety self-destructing syringe, described convex body in the form of sheets.
Convex body in the form of sheets has better elasticity, and when keeper abutted on the convex body, convex body expanded outwardly easily, makes keeper better by convex body, alleviates patient's pain.
In above-mentioned safety self-destructing syringe, described convex body is at least two and along the needle holder axial distribution, and staggers in its radial position.
It is in order can better to prevent that keeper from being stopped by convex body when the keeper clamping, to be unlikely to when retracting injection rod keeper is pulled out in needle holder that convex body is at least two, but pulls out together positioning seat is whole.Convex body is provided with when keeper passes through convex body like this along the needle holder axial distribution, contacts with a convex body earlier, by contacting with second convex body again behind the convex body, then, shot thrust is divided into multiple injection thrust, the pain when alleviating patient infusion by second convex body.Keeper radially staggers and is arranged in the needle holder, avoids all convex bodys all to be positioned at the same side of needle holder, prevents that injection rod from retracting in the process because the needle holder unbalance stress causes the result that needle holder can not be pulled out.
In above-mentioned safety self-destructing syringe, described convex body is 2-6.
Guaranteeing to be stopped effectively by convex body that keeper can be chosen the quantity of one group of number as self wantonly under the situation that also needle holder can be retracted in the array of 2-6 after keeper is by convex body.Consider the processing situation of economic conditions and needle holder, convex body is set to 6 at most; Consider after keeper is by convex body can be effectively to be greater than frictional force between needle holder and the injection tube by the power that convex body stops and convex body bears when retracting injection rod, the number that convex body is minimum is decided to be 2.
In above-mentioned safety self-destructing syringe, described convex body is 2.The preferred version of convex body is 2, and 2 convex bodys lay respectively on the relative bus along needle holder axial distribution and 2 convex bodys.
In above-mentioned safety self-destructing syringe, described injection rod is provided with some baffle rings, has on the described rubber stopper and the corresponding annular groove of baffle ring.During assembling, the annular groove on the baffle ring on the injection rod and the plug forms and cooperates, makes being connected firmly of injection rod and plug, make inject and the drawing liquid process more stable.
Compared with prior art, the safety self-destruction syringe has the following advantages:
1, convex body is set directly on the needle holder in the safety self-destruction syringe, and needle holder is easy to be pulled in the injection tube under the situation that convex body can effectively stop keeper, and the effect of self-destruction is more obvious.
2, convex body is at least two and along the needle holder axial distribution, and its radial position staggers, and is provided with like this, shot thrust is divided into multiple injection thrust, the pain when alleviating patient infusion; But also avoid all convex bodys all to be positioned at the same side of needle holder, prevent that injection rod from retracting in the process because the needle holder unbalance stress causes the result that needle holder can not be pulled out.
3, convex body in the form of sheets has better elasticity, and when keeper abutted on the convex body, convex body expanded outwardly easily, makes keeper better by convex body, alleviates patient's pain.
