Specific embodiment
Illustrate herein first, in the following embodiment and schema that will be introduced, identical reference number is indicated identical
Or similar component or its structure feature.
Please referring initially to Fig. 3, the interior fistula wing needle 10 of the utility model includes a needle stand 20, a needle body 60 and an infusion
Pipe 62.
Needle stand 20 as elastic material in a manner of being integrally formed made by (such as plastic ejection moulding technique), it includes lead
30, two fins 40 of pipe and a protecting cover 50, as shown in Figures 1 and 2:
Conduit 30 is in hollow form and has a front end 32 and a rear end 34.
Two fins 40 are connected to the arranged on left and right sides face of conduit 30, and the top surface of one of fin 40 has a positioning
The top surface of protrusion 42, another fin 40 has a location indentations 44.In addition, as shown in Fig. 2, the bottom surface of each fin 40
With an on-slip lines 46.
Protecting cover 50 is connected to the left side of the front end 32 of conduit 30, more particularly, as shown in Fig. 1, Fig. 6 and Fig. 7, protecting cover
50 have a roof 51, a bottom wall 52, an end wall 53, one side wall 54 and a connection wall 55, and end wall 53 is connected to top, bottom wall 52
Front end, side wall 54 connect the left side of roof 51, bottom wall 52 and end wall 53, so that opened each other around out one towards right side
Hold needle tray 56, be connected to as connection wall 55 between the front end of conduit 30 and the rear end of side wall 54, enables protecting cover 50 is opposite to lead
Pipe 30 makees elastics wing.In addition, in the present embodiment, roof 51 and bottom wall 52 have respectively shown in as shown in Figure 1, Figure 2, Fig. 6 and Fig. 7
There is an opening 57, this two openings 57 mutually stagger in tandem, and more there are two elastomeric ribs 58, elastomeric ribs for protecting cover 50
58 one end is connected to the peripheral wall of opening 57 and tiltedly stretches from opening 57 towards the direction for holding needle tray 56.
However herein it should be added that, opening 57 and the quantity of elastomeric ribs 58 can carry out according to actual needs
Adjustment, as long as at least one, more particularly, opening 57 is set to one of top, bottom wall 51,52, elastomeric ribs 58
One end be integrally connected opening 57 peripheral wall and from opening 57 towards hold needle tray 56 direction tiltedly stretch, so can also provide calmly
Position effect.
Needle body 60 can be fixed on the front end of conduit 30 with integrally formed mode (such as metal embedment injection molding),
Also it can use the front end that an adhesive agent is fixed on conduit 30, be not limited herein.After needle body 60 is fixed on conduit 30,
Needle body 60 is located on the central axis A of conduit 30, thus, when protecting cover 50 is located at a release position P1 (as shown in Figures 1 and 3)
When, the central axis A of conduit 30 will not be by the appearance needle tray 56 of protecting cover 50, so that needle body 60 is exposed outside completely, when protecting cover 50
When setting P2 positioned at a lid coincidence (as shown in Figure 5 and 7), the central axis A of conduit 30 passes through the appearance needle tray 56 of protecting cover 50, makes needle
Body 60 is located in the appearance needle tray 56 of protecting cover 50 to avoid exposed.In addition, the meeting when needle body 60 is located in the appearance needle tray 56 of protecting cover 50
It is positioned simultaneously by two elastomeric ribs 58, as shown in FIG. 6 and 7, to ensure that protecting cover 50 will not divide easily with needle body 60
It opens.
Perfusion tube 62 is sheathed on the rear end 34 of conduit 30, to convey medicament or blood.
It can be seen from the above, when to be injected, with finger by protecting cover 50 from lid coincidence as shown in Figure 5 set P2 pull to
Release position P1 as shown in Figure 3, is exposed outside needle body 60 completely, then pinches two fins 40 with two fingers again,
As shown in figure 4, abutting each other the top surface of two fins 40, positioning convex portion 42 at this time can be mutually embedding with location indentations 44
Card influences the stability of injection process to avoid two relative movements of fin 40, can be inserted into needle body 60 be intended to infuse later
The position penetrated discharges the strength to two fins 40 after the insertion for completing needle body 60, and utilizes adhesive tape by two wings
Piece 40 sticks on skin, the position that at this time further can stablize needle body 60 using the on-slip lines 46 of two fins 40
It sets, medicament can be so delivered in human body by perfusion tube 62, or blood is extracted out out of human body.
Needle body 60 extracted out after completing said injector movement, then with finger by protecting cover 50 from opening as shown in Figure 3
Position P1 is pushed to lid coincidence as shown in Figure 5 and sets P2, holds in needle tray 56 and by two elastomeric ribs until needle body 60 is located at
58 position i.e. completion storage (as shown in FIG. 6 and 7).
In conclusion needle stand 20 provided by the utility model is made by integrally formed mode, with common technology
In contrast, not only effectively simplify structure and reduce manufacturing cost, only need a finger can be complete when storing needle body 60
At the operation of protecting cover 50, and then the chance that hand is contacted with needle body 60 is greatly decreased, increases operation ease and promotion to reach
The purpose of narrowing safety.
