Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of safety shield of intravenous needle.
Background technology
Data according to the relevent statistics, China is venous transfusion, the most general country of blood sampling.Ji Ge medical institutions of hospital have a large amount of used intravenous needles to go out of use every year.For fear of environmental pollution and refuse secondary, utilize, need to used intravenous needle be recycled by professional institution.In order to prevent that in removal process unexpected injury or superinfection are to related personnel, hygiene department needs intravenous needle sheath a kind of simple in structure, safe and reliable badly.
Utility model content
This utility model object is to provide a kind of intravenous needle sheath simple in structure, esy to use, safe and reliable.
This utility model comprises anterior sheath, rear portion pleated sheet, described rear portion pleated sheet is connected to the rear end of described anterior sheath, the bottom of described anterior sheath arranges axially open, described anterior sheath and described rear portion pleated sheet can fasten mutually, in the front portion of described anterior sheath, a pair of buckle is set, described buckle is wholely set the axial open end at described anterior sheath, and block button hole corresponding to a pair of and described buckle is set at the rear portion of described rear portion pleated sheet.
This utility model is when assembling, rear portion pleated sheet is the folding axially open that covers anterior sheath forward, 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, by fin, syringe needle is pushed in sheath, then send into recovery link, can avoid being like this scratched in removal process, avoided infection, this jacket structure is simple, use is also convenient.
This utility model arranges two revetments at the rear portion of described rear portion pleated sheet, and described two revetments are separately positioned on the outside of described two block button holes; Described revetment can buckle into hole as stop convenient card when assembling, also can protect buckle to prevent that it from causing accidental because external force is loosening.
This utility model arranges a limited step at the rear portion of described rear portion pleated sheet, and when needle body slips into after sheath, intravenous needle fin is positioned in this limited step back cavity, and it can prevent that needle body from departing from sheath easily, further guaranteed safety.
This utility model arranges an angled protrusions at the rear portion of described anterior sheath, and described angled protrusions is arranged on the axial open end of described anterior sheath, in the front portion of described rear portion pleated sheet, the spacing preiection coordinating with described angled protrusions is set; After described angled protrusions, spacing preiection coordinate, when intravenous needle skids off sheath in use, the fin of intravenous needle falls into spacing the place ahead that two projections cooperatively interact, and such is spacing, the interactive and impact operation of sheath in the time of can avoiding using.
This utility model arranges an inside protruding top on the leading section sidewall of described anterior sheath; This set can be the diameter that the diameter of sheath is less than tube for transfusion, utilizes the elasticity of tube for transfusion, and tube for transfusion is compressed firmly and is limited in safety shield, this spacing further safety effect that plays equally.
