By blood sampling needlestick injury accident, hepatitis B, hepatitis C virus and the AIDS disease for wherein at least having over thousands of people that can be adhered on syringe needle
Poison infection.The emergency treatment expense that the medical staff stabbed every time because blood collection needles are broken and patient generate is per capita 3000
Dollar.
Domestic and international company puts into the research and development of safety blood taking medical equipment energetically in succession, and safe blood-taking needle currently on the market is non-
The situation of Chang Duo, safety blood taking have already turned on, but to promote safety blood taking completely has one section of very long road to walk.Currently on the market
These safety blood taking equipment have many deficiencies：One is the production cost is very high；The second is production technology is complicated；The third is
The quality of production is difficult to ensure；The fourth is medical staff is cumbersome；The fifth is security function is difficult to ensure.
Therefore, in view of the above-mentioned problems, the utility model proposes a kind of new technical solutions.
Utility model content
The purpose of this utility model be to provide it is a kind of simple in structure, it is easy to operate, hide needle using the sliding of protective case
Head effectively prevents the disposable casing safety blood taking needle of security risk.
The utility model is achieved through the following technical solutions：
A kind of disposable casing safety blood taking needle, including pedestal and protective case, the protective case are set on pedestal,
The pedestal end is equipped with blood taking needle, and the pedestal both sides are equipped with guide rod, and guide rod end is equipped with spring secures rail to sleeper, described
Pedestal end is equipped with needle stand, and the blood taking needle is fixedly mounted on needle stand, and needle stand upper end both sides are equipped with limiting slot, described
Protective case both sides are equipped with sliding block, and the sliding block is slided up and down by guide rod in pedestal, and the protective case both sides are equipped with card slot,
The card slot is located at sliding block lower end, cooperates between the card slot and spring secures rail to sleeper and limiting slot, completes the limit of protective case.
Further, the protective case is equipped with baffle close to needle stand one end, and the length of the baffle is the length of blood taking needle
Degree.
Further, gap is equipped between the limiting slot and spring secures rail to sleeper, the card slot is stuck in limiting slot and elastic buckles
Interference fit is realized between part.
Further, the end face of the spring secures rail to sleeper is intermediate incline structure.
Further, the pedestal, guide rod, spring secures rail to sleeper, limiting slot and needle stand are structure as a whole, by being molded into
Type.
Further, the protective case, sliding block and card slot are structure as a whole, and pass through injection molding.
The beneficial effects of the invention are as follows：The utility model proposes blood taking needle it is simple in structure, it is easy to operate, after the completion of blood sampling
By the sliding of sliding block, protective case is set to be moved to syringe needle direction, then by coordinating between spring secures rail to sleeper, limiting slot and card slot, it is real
Syringe needle, is ensconced the baffle lower end of protective case by existing engaging of the protective case with pedestal, and it is hidden to efficiently avoid safety existing for syringe needle
Suffer from, moreover, entire combine only has two components, it is easy for installation.
