Abstract
The utility model provides a venous transfusion needle safety shield, belongs to medical instrument, and the axis direction safety shield who follows tubular safety shield comprises upper and lower two parts, the lower part is the U type elongated slot body, and upper portion is buckle closure, buckle closure and U -shaped elongated slot body lock, the U type elongated slot body is equipped with relatively along two notches of axis direction on and inlays the mouth, inlays the both ends that the mouth lies in two notches in U type elongated slot body upper end respectively for inlay the needle wing of dress transfusion needle, the one end of buckle closure is articulated with the U type elongated slot body, and the other end of buckle closure is equipped with the button hole, clamps with the buckle of U type elongated slot end of body setting. The utility model has the advantages that: after the infusion was accomplished, the needle wing pushed away to the recess of U type cell body near -end in, until shielding the needle point completely, can not stab anyone. After shielding the needle point, U type cell body and buckle closure spiral -lock can prevent it and return initial position, have improved the reliability of protection. Adopt hard material, be the tubular structure, the resistance to compression bending resistance. Install safety shield again at the transfusion needle post assembling, production simple process is convenient.
Description
Technical field
This utility model belongs to a kind of single use medical apparatus and instruments, particularly a kind of venoclysis needle safety shield.
Background technology
Single use venoclysis needle (hereinafter referred to as transfusion needle) is the single use medical apparatus and instruments for clinical transfusion, is connected jointly forms fluid passage during transfusion with transfusion device, and medicinal liquid is introduced patient's vein by container.Transfusion needle forms the pipeline of connecting by sheath, needle tubing, the pin wing, flexible pipe, adapter.Needle tubing adopts austenitic stainless steel, and other parts are made up of medical macromolecular materials.
Original transfusion needle directly abandons after using, and the needle point of waste products is easy to scathing, comprises nursing staff, cleanup crew etc.The blood that used transfusion needle has patient to remain, easily makes the person of being wounded by stabbing infect.Clinical transfusion pin use amount is huge, and this risk also extensively exists.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect, provides a kind of venoclysis needle safety shield, and this safety shield can avoid clinical transfusion to treat the needle pricks people of discarded transfusion needle, causes infection.
The purpose of this utility model is achieved through the following technical solutions: a kind of venoclysis needle safety shield, is characterized in that: described safety shield is tubular, and the axis direction safety shield along safety shield is made up of upper and lower two parts; Bottom is U-shaped elongated slot body, and top is buckle closure, and buckle closure and U-shaped elongated slot body fasten; U-shaped elongated slot body two notches are in the axial direction provided with embedding mouth relatively, and embedding mouth lays respectively at the two ends of two notches in U-shaped elongated slot body upper end, for the pin wing of setting-in transfusion needle; One end and the U-shaped elongated slot body of buckle closure are hinged, and the other end of buckle closure is provided with buttonhole, and the buckle arranged with U-shaped elongated slot end of body clamps.
Advantage of the present utility model and beneficial effect are:
1, U-shaped elongated slot body can move relative to pin wing slip, before transfusion needle uses and when using, the pin wing is fixed in the embedding mouth of U-shaped elongated slot body far-end, do not affect the use of transfusion needle, after transfusion completes, manually the pin wing is pushed in the embedding mouth of U-shaped elongated slot body near-end, until covered needle point completely, can not be stabbed anyone.
2, after covering needle point, the buckle that U-shaped elongated slot body is furnished with, by with buckle closure spiral-lock, the pin wing is stuck in the embedding mouth of U-shaped elongated slot body, can prevents it from returning initial position, improve the reliability of protection.
3, safety shield adopts hard material, and in tubular construction, resistance to compression bending resistance, effectively can cover needle point, prevents needle point from exposing safety shield.
4, the U-shaped elongated slot body of safety shield and buckle closure hinged folding after become tubulose, after transfusion needle assembling, can install safety shield again, production technology is simple and convenient.

Detailed description of the invention
Embodiment: as shown in figures 1 to 6, a kind of venoclysis needle safety shield, described safety shield is tubular, and the axis direction safety shield along safety shield is made up of upper and lower two parts; Bottom is U-shaped elongated slot body 1, and top is buckle closure 2, and buckle closure 2 and U-shaped elongated slot body 1 fasten; U-shaped elongated slot body 1 two notches are in the axial direction provided with embedding mouth 4 relatively, and embedding mouth 4 lays respectively at the two ends of two notches in U-shaped elongated slot body 1 upper end, for the pin wing 5 of setting-in transfusion needle; One end and the U-shaped elongated slot body 1 of buckle closure 2 are hinged, and the other end of buckle closure 2 is provided with buttonhole 7, and the buckle 6 arranged with U-shaped elongated slot body 1 end clamps.
Operation principle:
U-shaped elongated slot body 1 can slide relative to the pin wing 5, before transfusion needle uses and when using, the pin wing 5 is installed in the embedding mouth 4 of U-type groove body 1 far-end, a part for infusion tube 3 is sleeping to be contained in U-shaped elongated slot body 1, buckle closure 2 and U-type groove body 1 spiral-lock, the pin wing 5 is blocked, does not affect the use of transfusion needle, comprise puncture patient vein, infuse and extract the processes such as needle tubing; After transfusion completes, open buckle closure 2, a hand-held U-shaped elongated slot body 1, pull infusion tube 3 on the other hand, the pin wing 5 is drawn in the groove 4 of U-shaped elongated slot body 1 near-end, until U-shaped elongated slot body 1 covered needle point completely, after covering needle point, buckle closure 2 blocks with the buckle 6 of U-shaped elongated slot body 1, the pin wing 5 is installed in the groove 4 of near-end, and clamp, can prevent it from returning initial position, improve the reliability of protection.
Safety shield adopts hard material, and in tubular construction, resistance to compression bending resistance, effectively can cover needle point, prevents needle point from exposing protective sleeve.
