In figure, the anterior sheath of 1-, 2-rear portion pleated sheet, 3-axially open, 4-buckle, 5-block button hole, 6-two panels revetment, 7-limited step, 8-angled protrusions, 9-spacing preiection, the convex top of 10-, 11-U type passage, 12-first card convex, 13-second card convex.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Embodiment 1
A kind of safe vein needle shield, as Figure 1-3, comprise anterior sheath 1, rear portion pleated sheet 2, described rear portion pleated sheet 2 is connected to the rear end of described anterior sheath 1, the bottom of described anterior sheath 1 arranges axially open 3, described anterior sheath 1 can fasten mutually with described rear portion pleated sheet 2, in the front portion of described anterior sheath 1, a pair buckle 4 is set, described buckle 4 is wholely set the axial open end at described anterior sheath 1, the rear portion of portion's pleated sheet 2 arranges a pair with described buckle to 4 block button holes of answering 5 in the rear, the rear portion of portion's pleated sheet 2 arranges two panels revetment 6 in the rear, described two panels revetment 6 is separately positioned on the outside of described two block button holes 5, described two panels revetment 6 is fastened and connected by the first card convex 12 and the second card convex 13 with the U-shaped passage 11 in described anterior sheath 1.
Namely described U-shaped passage 11 and described two panels revetment 6 once reach self-locking state after fastening, non-dismountable.
The rear portion of portion's pleated sheet 2 arranges a limited step 7 in the rear.
Arrange an angled protrusions 8 at the rear portion of described anterior sheath 1, described angled protrusions 8 is arranged on the axial open end of described anterior sheath 1, and the front portion of portion's pleated sheet 2 arranges the spacing preiection 9 coordinated with described angled protrusions 8 in the rear.
A convex top 10 is provided with in the bottom of described U-shaped path 10.
The cross sectional shape of described first card convex 12 and the second card convex 13 is triangle, described in barb-like in upwards of a pair first card convexs 12 being oppositely arranged, described in multipair second card convex 13 that is oppositely arranged in downward barb-like.Barb-like card convex is combinable more firm.
The blood taking needle of the present embodiment is when assembling, rear portion pleated sheet collapsed forward covers the axially open of anterior sheath, by coordinating of buckle and block button hole, form complete intravenous needle sheath, after having assembled, tube for transfusion is arranged in anterior sheath, and the fin of intravenous needle is clipped between anterior sheath and rear portion pleated sheet; During use, by fin, syringe needle is released; After using, push in sheath by fin by syringe needle, then feeding reclaims link, can avoid like this being scratched, avoid infection in removal process, and this jacket structure is simple, use also facilitates.
The rear portion of rear portion pleated sheet arranges two panels revetment, and described two panels revetment is separately positioned on the outside of described two block button holes; Described revetment can buckle into hole when assembling as stop convenient card, and buckle also can be protected to prevent it from causing accidental because external force loosens.Two panels revetment is arranged triangle card convex, can screens easily, do not affect buckle hand-hole simultaneously.
The rear portion of described rear portion pleated sheet arranges a limited step, and after needle body slips into sheath, intravenous needle fin is positioned in this limited step back cavity, and it can prevent needle body from departing from sheath easily, further ensures safety.
The rear portion of described anterior sheath arranges an angled protrusions, and described angled protrusions is arranged on the axial open end of described anterior sheath, and the front portion of portion's pleated sheet arranges the spacing preiection coordinated with described angled protrusions in the rear; After described angled protrusions, spacing preiection coordinate, when intravenous needle skids off sheath in use, the fin of intravenous needle falls into the spacing front that two projections cooperatively interact, and such is spacing, sheath interactive and impact operation when can avoid using.
The leading section sidewall of described anterior sheath is arranged an inside convex top; This set can be the diameter that the diameter of sheath is less than tube for transfusion, utilizes the elasticity of tube for transfusion, is compressed firmly by tube for transfusion and be limited in safety shield, thisly spacingly plays further safety effect equally.
