Abstract
The invention relates to a skin pricking needle, and provides the skin pricking needle which is easy to control skin pricking depth, causes little pain, and has accurate test results and high detection efficiency. The skin pricking needle comprises an elongated needle body and a limiting piece; the limiting piece is provided with a through hole and comprises an extension fixing edge and a limiting edge; the needle body penetrates into the through hole of the limiting piece; the extension fixing edge of the limiting piece is fixed on the needle body by welding; a wrinkle with a transition fillet is formed outside the limiting edge; when a skin allergy prick test is performed, the pricking needle cannot prick into a corium layer, so that bleeding can be avoided; therefore, an accurate test result is obtained, and the detection efficiency of an operator is greatly improved; moreover, the welding contact area is large enough, so that the limiting piece is installed on the needle body more firmly; in addition, the skin pricking needle is simple in structure and low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of pin, relate in particular to a kind of type skin pricking needle.
Background technology
The irritated test of existing human body skin, mainly to test to obtain desired data by skin prick, what mainly adopt clinically at present is the skin prick anaphylactogen---sterilization patient bilateral forearm, in the forearm inboard on 3-5cm drips an anaphylactogen medicinal liquid (approximately 20 kinds), and drip Skin prick testing and normal saline negative control arranged, in medicinal liquid central authorities by the vertical prick skin of disposable aspiration needle to subcutaneous, observe 20 minutes, compare with histamine group and saline group, record welt and position and size occur.But for the operator, abecedarian especially, syringe needle thrusts degree of depth Chang Buneng to be held, and thrusts shallowly, skin can not be punctured, and may cause false-negative result.Thrust deeply, pain is strong, thrusts skin corium, causes hemorrhagely, will affect test result, thereby the operator be can not let go when operation, makes detection efficiency excessively slow.
Summary of the invention
Technical problem to be solved by this invention is: a kind of type skin pricking needle that skin depth is easily held, pain is few, test result is accurate, detection efficiency is high that thrusts is provided.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of type skin pricking needle, the needle body that comprises strip, comprise banking stop, described banking stop has through hole and comprises prolongation fixed edge and position-limited edge, described needle body penetrates the through hole of banking stop, and the prolongation fixed edge by banking stop is weldingly fixed on needle body, and the described position-limited edge outside is provided with the band knuckle and turns up.
The beneficial effect of a kind of type skin pricking needle provided by the invention is: owing to being welded with banking stop on needle body, therefore after the operator punctures detected person's skin surface by needle body, banking stop and skin butt, produce larger contact area, make needle body no longer continue to thrust in detected person's skin, reduced detected person's pain, can not thrust skin corium, avoid causing hemorrhage, thereby obtain test result accurately, and the operator is without the degree of depth of considering that pricking needles thrusts, the degree of depth that each pricking needles thrusts skin will produce by banking stop is fixing, make the operator greatly improve detection efficiency, and shank is thinner, banking stop is thinner, by extending fixed edge, banking stop is weldingly fixed on needle body, can make to weld contact area enough large, allow banking stop more firmly be arranged on needle body, and position-limited edge outside band knuckle is turned up, can effectively avoid scratch skin, and this pricking needles is simple in structure, low cost of manufacture.
The technical scheme that the invention provides improved a kind of type skin pricking needle is: the top edge of turning up with knuckle on described position-limited edge inwardly shrinks, and can avoid better scratch skin like this.
The invention provides the further technical scheme of improved a kind of type skin pricking needle is: described needle body comprises syringe needle and shank, described syringe needle is conical syringe needle, described shank is cylindrical shank, the bottom surface of banking stop is positioned at the junction of syringe needle and shank, need only like this regular length of syringe needle being arranged to the prick skin top layer, after syringe needle all thrusts skin, banking stop and skin butt, thereby the control point pricker thrusts the degree of depth of skin more accurately, make operation easier.
The invention provides the technical scheme of further improved a kind of type skin pricking needle again is: described needle body afterbody is provided with spheroid, by spheroid, makes the operator can better grip pricking needles.
The invention provides the further technical scheme of improved a kind of type skin pricking needle is: described spheroid is that soft rubber material is made, spheroid is made by soft rubber material and is had elasticity, make the operator hold the pricking needles feel better, in order to hold more accurately the pricking method dynamics.
Below in conjunction with drawings and Examples, a kind of type skin pricking needle of the present invention is further described in detail.
The accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of type skin pricking needle of the present invention.
Fig. 2 is the cutaway view of a kind of type skin pricking needle in Fig. 1.
Fig. 3 is the cutaway view of a kind of banking stop of type skin pricking needle in Fig. 1.
Specific embodiment
As Fig. 1, Fig. 2, shown in Fig. 3, the embodiment of a kind of type skin pricking needle of the present invention, the needle body 1 that comprises strip, comprise banking stop 2, described banking stop 2 has through hole 4 and comprises prolongation fixed edge 2-1 and position-limited edge 2-2, described needle body 1 penetrates the through hole 4 of banking stop 2, prolongation fixed edge 2-1 by banking stop 2 is weldingly fixed on needle body 1, the described position-limited edge 2-2 outside is provided with the band knuckle and turns up 2-3, the top edge of turning up 2-3 with knuckle on described position-limited edge 2-2 inwardly shrinks, needle body 1 comprises syringe needle 1-1 and shank 1-2, described syringe needle 1-1 is conical syringe needle 1-1, described shank 1-2 is cylindrical shank 1-2, the bottom surface of banking stop 2 is positioned at the junction of syringe needle 1-1 and shank 1-2, described needle body 1 afterbody is provided with spheroid 3, described spheroid 1 is made for soft rubber material.
Be below to detailed description of the invention: the needle body 1 of a strip comprises cone shape syringe needle 1-1 and columned shank 1-2, syringe needle 1-1 and shank 1-2 produce junction, syringe needle 1-1 is through banking stop 2 through holes 4, be positioned at the junction of syringe needle 1-1 and shank 1-2 to the bottom surface of banking stop 2, make banking stop 2 belows only have syringe needle 1-1 part, prolongation fixed edge 2-1 by banking stop 2 is weldingly fixed on needle body 1 again, like this when manufacturing the production pricker, first the length of syringe needle 1-1 is fixedly installed, it is merely able to is that the prick skin top layer is to subcutaneous length, after thrusting, syringe needle 1-1 make it can't continue to thrust by banking stop 2 butts, thereby it is little that the detected person is keenly felt, detection efficiency is high, detect accurately, extending fixed edge 2-1 strengthens banking stop 2 and the contact area of needle body 1, allow banking stop 2 be more prone to be welded on needle body 1 and more firm, be provided with at needle body 1 afterbody the spheroid 3 that soft rubber material is made, the operator is being held more comfortable.
