Abstract
A kind of skin prick tests dual spring pin, including syringe needle, needle stand, surface push-rod and housing, cross-drilled hole that is mutually angled and being interconnected and vertical core are provided with housing, needle stand is provided with vertical core, surface push-rod is provided with cross-drilled hole, needle stand afterbody is provided with an inclined-plane, dovetail groove is provided with inclined-plane, it is engaged with the projection of surface push-rod so that projection can only be slided in dovetail groove, so surface push-rod movement in the cross-drilled hole can cause needle stand to move in vertical core, surface push-rod afterbody stretches out housing and is provided with push-plate, it is provided with bulky spring to allow to promote push-plate rebound automatically after compressing bulky spring relieving push-plate between push-plate and housing.
Description
Technical field
The present invention relates to a kind of pin, more particularly to a kind of skin prick experiment dual spring pin.
Background technology
Existing human body skin allergy test, mainly tests to obtain desired data by skin prick, clinical at present
On mainly use skin prick anaphylactogen --- sterilization patient's bilateral forearm, one drip in the 3-5cm drops in inner forearm
Allergy original liquid (about 20 kinds), and drop has Skin prick testing and physiological saline negative control, uses disposable pin in liquid central authorities
Head perpendicular insertion broken skin skin is observed 20 minutes, is compared with histamine group and salt solution group to subcutaneous, and position and size occurs in record wheal.
But for operator, especially beginner, syringe needle is pierced into depth and can not often hold, was pierced into shallow, it is impossible to puncture skin, may
Cause false-negative result.Piercing is too deep, and pain is strong, is pierced into skin corium, causes bleeding, will affect test result, so that
Operator is can not let go in operation, makes detection efficiency excessively slow.
The content of the invention
The technical problem to be solved is：Skin depth is easily held, pain is few, test to provide a kind of piercing
As a result accurately, the high skin prick experiment dual spring pin of detection efficiency.
To solve above-mentioned technical problem, the present invention is employed the following technical solutions：A kind of skin prick tests dual spring pin, bag
Syringe needle, needle stand, surface push-rod and housing are included, cross-drilled hole that is mutually angled and being interconnected and vertical core in housing, is provided with,
Needle stand is provided with vertical core, surface push-rod in cross-drilled hole, is provided with, needle stand afterbody is provided with an inclined-plane, and thin bullet is provided between needle stand and housing
Spring, the movement in the cross-drilled hole of such surface push-rod can cause needle stand to move in vertical core, and surface push-rod afterbody stretches out housing and sets
There is push-plate, between push-plate and housing, be provided with bulky spring, promote push-plate compress bulky spring, bulky spring can be certainly after decontroling push-plate
Move back.
The present invention provides a kind of beneficial effect of skin prick experiment dual spring pin：So design, promote surface push-rod
Syringe needle easily can be slowly promoted to be pierced into skin so that user has relatively comfortable experience, and inclined-plane plays increase rise
Effect make it easier to control pin speed and strength, can be automatically replied using spring, convenient use, and be subject to spring
Pressure greatly increase the depth and dynamics that feel so can very easily control pin, improve the comfort level of user.
Further, preferably, surface push-rod is square, pushing course is difficult to swing, more stable reliability.
Further, needle stand is square, and pushing course is difficult to swing, more stable reliability.
Description of the drawings
Fig. 1 tests dual spring pin fore-and-aft direction cross-sectional schematic for a kind of skin prick of the invention；
Specific embodiment
As needed, the specific embodiment of the present invention is disclosed herein, it will be appreciated that the disclosed embodiments are
The demonstration present invention, the present invention can be implemented with different and alternative form.Accompanying drawing is not necessarily drawn to scale, and some features can be overstated
It is big or reduce the details of particular elements is shown.Therefore, concrete structure disclosed herein and function detail are understood not to
It is in a limiting sense, but it is only of the invention to instruct those skilled in the art differently to adopt as representative basis.Based on this
Embodiment in invention, the every other reality obtained under the premise of creative work is not made by those of ordinary skill in the art
Example is applied, the scope of protection of the invention is belonged to.
As shown in figure 1, a kind of skin prick tests dual spring pin, including syringe needle 1, needle stand 2, surface push-rod 3 and housing 6,
Cross-drilled hole 7 that is mutually angled and being interconnected and vertical core are provided with housing 6, needle stand 2 are provided with vertical core, are set in cross-drilled hole 7
There is surface push-rod 3,2 afterbody of needle stand is provided with an inclined-plane, and hairspring 13 is provided between needle stand 2 and housing 6, and such surface push-rod 3 exists
Movement in cross-drilled hole 7 can cause needle stand 2 to move in vertical core, and 3 afterbody of surface push-rod stretches out housing 6 and is provided with push-plate 4, push-plate 4
Bulky spring 5 is provided between housing 6, promotes push-plate 4 compress bulky spring 5, bulky spring 5 can be with appliance for releasing single after decontroling push-plate 4
Return.
