Detailed description of the invention
As it is shown in figure 1, this utility model provides a kind of dual anti-pricking wound safety device, its structure includes needle tubing sleeve 1, and described needle tubing sleeve 1 is the pipe of hollow, and the sidewall of described needle tubing sleeve 1 is offered chute 2, and described chute 2 is provided with open end 21 and blind end 22.As the embodiment that can select, on described needle tubing sleeve 1, the side near described blind end 22 is provided with sleeve shank 5, and the draw ratio of described needle tubing sleeve 1 is 1:10-1:15, and the length ratio of the length of described chute 2 and described needle tubing sleeve 1 is 4:5.
Described needle tubing sleeve 1 is applied to Anti-stabbing puncture needle, described Anti-stabbing puncture needle includes syringe needle 6 and pinhead handle 7, described needle tubing sleeve 1 is sheathed on the outside of described syringe needle 6, and described syringe needle 6 slidably reciprocates between described open end 21 and described blind end 22 along described chute 2.
As the embodiment that can select, as shown in Figure 2, opening part in described open end 21 is provided with a catch 3, described catch 3 is rectangle flexure strip, described catch 3 includes fixing end 41 and movable end 42, the sidewall of described fixing end 41 and described needle tubing sleeve 1 is connected for fixing, and the sidewall of described movable end 42 and described needle tubing sleeve 1 is for being flexibly connected.So that the used time, first open described catch 3, described needle tubing sleeve 2 is set in outside syringe needle 6, the opening of described open end 21 is sealed again with catch 3, prick into human body (see Fig. 3) after syringe needle 6 comes off can be prevented effectively from from open end 21, when carrying out puncture procedure, described needle tubing sleeve 1 is without taking, only directly described needle tubing sleeve 1 need to be pushed into described chute blind end 22 backward to abut with pinhead handle 7, at this moment pinhead handle 7 moves from open end 21 to blind end 22, as preferred embodiment, as shown in Figure 4, when the blind end 22 of described pinhead handle 7 with described needle tubing sleeve 1 abuts, by arranging described sleeve shank 5 and the distribution in buttferfly-type of described pinhead handle 7, be conducive to improving described needle tubing sleeve 1 fixing and stable on syringe needle 6.
Puncture complete pull out pin after, described needle tubing sleeve 1 is pushed into forward in the process on syringe needle 6 top, pinhead handle 7 moves from blind end 22 to open end 21, until syringe needle is covered without prick into human body by described needle tubing sleeve 1 completely, and described catch 3 guarantees that again syringe needle 6 will not come off and prick into human body in sliding process in needle tubing sleeve 1 in the process.
