Description
Technical field
Medical instruments field is the utility model is related to, more particularly to a kind of new micro- sense safe blood-taking needle.
Background technology
Often there are blood test, chemical examination and sampling in the clinical laboratory of hospital and blood sampling mechanism, these are required for using blood taking needle
To complete.And blood taking needle is using preceding can't see needle point, the pain that pin is pricked can produce patient to fear or the frightened heart
Reason, prevent patient from being well matched with the operation of medical personnel.
In addition pricking wound is one of harm of most serious that clinical staff is faced, disease prevention and control center of the U.S.
Surveillance is pointed out, 1,000,000 pricking wounds at least occur every year, wherein 80% pricking wound occurs, in nursing staff, to stab
Reason is due to that blood taking needle is exposed to outside using rear needle point, needs artificial treatment to pull up syringe needle, due to the syringe needle after blood sampling outside
Dew, staff are easy to imprudence in processing and pricked, can cause cross-infection, certain potential safety hazard be present.In addition adopt
Blood pin is easily reused, and easily causes more people's cross-infections.
The content of the invention
In view of the shortcomings of the prior art and defect, there is provided a kind of new micro- sense safe blood-taking needle, pass through guide pad with being oriented to
Groove coordinates, and avoids syringe needle and is shaken in percussion so that syringe needle can move along a straight line, and alleviate pain when syringe needle is pierced into skin
Pain.But also secondary use is avoided that, it can effectively prevent cross-infection.
To achieve the above object, the utility model provides following technical scheme.
A kind of new micro- sense safe blood-taking needle, including housing, needle body, sliding sleeve, bonnet, the first spring and second spring, shell
Body is the tubular of both ends open, and bonnet covers and closes the first end of housing, and for needle body in housing, second spring is located at needle body
Between bonnet, needle body is provided with syringe needle, and sliding sleeve is stretched in housing from second end of the housing and coats needle body, and the first spring is set
Between sliding sleeve and needle body, sliding sleeve is provided with the through hole passed through for syringe needle, and sliding sleeve is provided with least one the first convex tendons, and first is convex
Muscle is provided with the first inclined-plane, and sliding sleeve is additionally provided with the groove positioned at the first convex tendon side, and inner walls are provided with the coordinated with groove
One guide rail, forms guide groove between the first guide rail and groove, needle body is provided with the guide pad coordinated with guide groove, set on guide pad
There is the second inclined-plane coordinated with the first inclined-plane.
Further, sliding sleeve is provided with second convex tendon parallel with the first convex tendon, between the first convex tendon and the second convex tendon
Chute is formed, inner walls are additionally provided with the second guide rail coordinated with chute.
Further, housing is provided with the positive stop lug boss coordinated with sliding sleeve.
Further, sliding sleeve outer sheath is provided with protective cap, and protective cap is on housing.
Further, housing outer surface is provided with the concave surface for being easy to hold with a hand.
Further, the spring fixed seat for being fixed thereon second spring is provided with bonnet.
The beneficial effects of the utility model are：Blood taking needle of the present utility model, protective cap is removed before use, is then pressed downwards
When pressing sliding sleeve, the first spring drives needle body to move downward, and compresses second spring simultaneously, now the first convex tendon drive guide pad to
Lower motion, when second spring can not be that guide pad can not move still further below in compression, guide pad passes through the second inclined-plane and first
Inclined-plane is fitted into guide groove, and the first convex tendon is no longer spacing to guide pad, and needle body is fast under the resilient force of second spring
Speed fires away, is injected syringe needle, after completing injection, unclamps sliding sleeve, slides over multiple under the resilient force of the first spring
Position, syringe needle is avoided to cause cross-infection outside.The fit clearance very little of guide pad and guide groove, needle body are exciting ejection
When going out, guide pad, close to linear motion, so that syringe needle can move along a straight line, alleviates syringe needle and is pierced into skin in guide groove
Pain during skin.When blood taking needle presses down on sliding sleeve again after, because guide pad is now placed in guide groove, first is convex
Muscle can not be spacing to guide pad so that needle body synchronously moves down with sliding sleeve, and syringe needle can not be exposed, and avoids the secondary wind used
Danger.
