Abstract
An expendable blood taking needle is composed of a needle sleeve with a push button at its one end and two opposite slide tracks on its inner surface, a needle body with a needle tip sleeve able to be broken, an elastic leaf group at another end of needle body, a safety plug on said needle tip sleeve, and a spring. Its application is also disclosed.
Description
Technical field:
The present invention relates to the technical field of blood taking needle, specifically a kind of disposable blood taking needle.
Background technology:
The blood taking needle that is adopted in the market; often do not force disposal type; the hazardness that exists secondary to use; cause the mutual infection between sufferer easily; there is great potential safety hazard; and existing disposal type blood taking needle often complex structure, processing technology require high; then make that production cost improves greatly; be difficult for applying; existing blood taking needle is not provided with protector simultaneously; user may be stabbed by needle point inadvertently, and safety is relatively poor, uses relatively difficulty especially for the old people.
Summary of the invention:
The object of the present invention is to provide a kind of improved blood taking needle, it can overcome blood taking needle in the prior art by secondary utilization, use is dangerous, cost is higher some shortcomings.
To achieve these goals, technical scheme of the present invention is: disposable blood taking needle, it mainly comprises needle guard and the needle body of establishing within it, and it is characterized in that: an end of needle guard is provided with a button, is provided with two corresponding chutes in the needle guard, chute is the list structure of projection, its shape matches with the profile of needle body, and the spacing between chute is less than the diameter of spring, and the end of needle body is arranged with a shell fragment group, the other end of needle body is provided with broken needle point cover, and needle point puts and is provided with safety cock.
Blood taking needle of the present invention need be turned on the broken needle point cover in needle body end earlier during use, makes whole blood taking needle be in state to be used, and after pressing button was downward, the projection on the push jack can force needle body to break away from fast and eject forward, and needle point produces the effect of puncture.When needle body marches forward, be compressed the elastic force that is produced between shell fragment on the needle body and the needle guard, needle body is return, when needle body is return, spring will be pushed down the needle body top, make needle body can not get back to original state, but owing to spring is blocked and can't travel forward again by chute, and spring also can't make needle body be forced out needle guard again, guarantee that blood taking needle can only be by disposable use, safety improves greatly, and simple in structure being easy to of entire product produced simultaneously, and cost is reduced greatly.

Fig. 1 is the structural representation of one embodiment of the invention
Fig. 2 is a decomposition texture sketch map of the present invention
Fig. 3 is the cutaway view of novel needle guard of the present invention
The specific embodiment:
The invention will be further described below in conjunction with drawings and Examples.
The present invention mainly comprises needle guard 1 and the needle body of establishing within it 2, its difference with the prior art is: an end of needle guard is provided with a button 3, be provided with two corresponding chutes 4 in the needle guard, chute is the list structure of projection, each chute is made of side by side two strip projected parts, its shape matches with the profile of needle body, make needle body to slide along the direction of chute, spacing between the chute is less than the diameter of spring, when spring is depressed into the chute end, will be blocked the way by chute, prevent that spring from further pressing down, the length of chute is greater than the length of needle body.One end of needle body is arranged with a shell fragment group 5, the other end of needle body is provided with broken needle point cover 6, so just guarantees that needle point can't be forced out needle guard under the situation of not twisting into two parts the needle point cover, increased the safety in the use, put at needle point simultaneously and be provided with safety cock 7.The top of shell fragment group is arranged with a spring 8, and this spring and button offset, and the left and right sides of button is respectively equipped with a push jack 9, and push jack is provided with an outside projection 10.
The shell fragment group is made of two corresponding plastics shell fragments, two shell fragments be respectively "/" and " " shape, be provided with in the needle guard and two corresponding stoppers in shell fragment position, the bottom of shell fragment is fastened on the stopper 11.It is one columned protruding 12 that one end of needle body is provided with, and this projection matches with the shell fragment group, is set in the shell fragment group, when shell fragment is moved downward by the thrust of button, just can promote needle body and move downward in the lump.Safety cock is two, is strip and is arranged on needle point cover surface symmetrically, and the bottom of needle guard is provided with the needle outlet that matches with needle point cover and safety cock shape.
In force, to twist into two parts the needle point cover of needle body end earlier, connecting portion between needle body and the needle point cover is relatively weaker, only need slightly firmly one twist promptly broken, at this moment whole blood taking needle just is in state to be used, after pressing the button, the push jack of button left and right sides will downward motion, and extrusion spring makes spring produce downward elastic force simultaneously, when push jack is run into two plastics shell fragments of shell fragment group, can force the plastics shell fragment to break away from stopping of the interior stopper of needle guard, and travel forward fast, under the effect of spring, the shell fragment group promotes needle body and ejects forward fast, needle point is finished the effect of puncture, when needle body travels forward, can produce elastic force because of the plastics shell fragment is compressed between shell fragment group and the needle guard, make needle body to swivel motion again, when the needle body resilience, spring just can be pushed down the top of needle body, makes needle body can't get back to original state, because spring is blocked and can't travel forward again by the needle guard internal chute, like this, blood taking needle just can't be used by secondary, has guaranteed the user and the person's of being punctured safety.
