Summary of the invention
The infusion set that provides a kind of use safer is provided the object of the invention.
To achieve these goals, the present invention adopts following technical scheme: safe transfusion device, comprise plastic spike, tube for transfusion, the Mo Feishi dropper, slide switch, filter, syringe needle, the syringe needle handle, described syringe needle rear portion is provided with trocar sheath, the syringe needle front portion is provided with needle sleeve, the needle sleeve rear portion is mounted slidably between trocar sheath and syringe needle, the needle sleeve front end is the bell structure, needle sleeve rear portion one side is provided with and pushes away handle, axially upper and arrange and push away the handle sliding tray with the corresponding position, handle position that pushes away of needle sleeve along trocar sheath, push away the handle notch in the rear end of sliding tray along the setting of trocar sheath circumferencial direction; The trocar sheath place corresponding with the syringe needle handle position arranges fixed handle, and the fixing band that cooperates with syringe needle handle and fixed handle of setting.
Be provided with diameter less than the floating block of Mo Feishi dropper inner diameter in the described Mo Feishi dropper, the floating block bottom is provided with magnetic piece, the Mo Feishi dropper inwall of floating block top is provided with link stopper, Mo Feishi dropper inner bottom part is provided with the hole suitable with the magnetic piece shape, be provided with the magnet of inhaling mutually with magnetic piece in the hole, be provided with one deck medical plastic layer on described magnetic piece and magnet and the face that internal liquid contacts.
Described and the needle sleeve lower end inwall syringe needle cooperation place is provided with sealing ring.
The magnetic stator of disc is set on the tube for transfusion at described syringe needle rear portion, and the magnetic fixing band is set cooperates with the magnetic stator.
Described syringe needle handle, fixed handle and fixing band adopt ferromagnetic material manufacturing and mutually adhesive setting.
The present invention can effectively prevent needle roller, and is convenient and practical, more safe and reliable.
The bell of needle sleeve front end can well protect the sharp place of syringe needle front end, can effectively prevent needle roller; Syringe needle handle and fixed handle are fixing more firm by fixing band, are provided with sealing ring with the needle sleeve lower end inwall of syringe needle cooperation place, play sealing function.Be provided with in magnetic piece and the hole in the Mo Feishi dropper with magnet that magnetic piece is inhaled mutually and cooperate, can be after medicinal liquid be totally lost, can adhesive prevent from being advanced into human body under the air when also having certain medicinal liquid in the Mo Feishi dropper, be provided with one deck medical plastic layer on magnetic piece and magnet and the face that internal liquid contacts, prevent from polluting medicinal liquid.The magnetic stator of disc is set on the tube for transfusion at syringe needle rear portion, and the magnetic fixing band is set cooperates fixed needle rear end tube for transfusion with the magnetic stator.Syringe needle handle, fixed handle and fixing band adopt ferromagnetic material manufacturing and mutually adhesive setting, conveniently fix and pull down.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Embodiment: safe transfusion device as shown in Figure 1, comprise plastic spike 1, tube for transfusion 15, Mo Feishi dropper 2, slide switch 5, filter 13, syringe needle 12, syringe needle handle 8, syringe needle 12 rear portions are provided with trocar sheath 7, be provided with sealing ring 14 with the needle sleeve 11 lower end inwalls of syringe needle 12 cooperation places, syringe needle 12 front portions are provided with needle sleeve 11, needle sleeve 11 rear portions are mounted slidably between trocar sheath 7 and syringe needle 12, needle sleeve 11 front ends are the bell structure, needle sleeve 11 rear portions one side is provided with and pushes away handle 10, axially upper and arrange and push away the handle sliding tray with the corresponding position, handle 10 position that pushes away of needle sleeve 11 along trocar sheath 7, push away the handle notch in the rear end of sliding tray along the setting of trocar sheath 7 circumferencial directions; Trocar sheath 7 places corresponding with syringe needle handle 8 positions arrange fixed handle 9, and the fixing band 19 that cooperates with syringe needle handle 8 and fixed handle 9 of setting, and syringe needle handle 8, fixed handle 9 adopt ferromagnetic material manufacturing and mutually adhesive setting with fixing band.
Be provided with diameter in the Mo Feishi dropper 2 less than the floating block 3 of Mo Feishi dropper 2 inner diameters, floating block 3 bottoms are provided with magnetic piece 16, Mo Feishi dropper 2 inwalls of floating block 3 tops are provided with link stopper 18, carry out spacing to floating block 3, Mo Feishi dropper 2 inner bottom parts are provided with the hole 4 suitable with magnetic piece 16 shapes, 4 are provided with the magnet 17 of inhaling mutually with magnetic piece 16 in the hole, are provided with one deck medical plastic layer on magnetic piece 16 and magnet 17 and the face that internal liquid contacts.
The magnetic stator 6 of disc is set on the tube for transfusion at syringe needle 12 rear portions, and the magnetic fixing band is set cooperates with magnetic stator 6, be convenient to fix, magnetic stator 6 also can be other shapes certainly.
Now syringe needle 12 is punctured such as correct position in the time of transfusion; then will push away handle 10 back-outs along pushing away handle notch rotation needle sleeve 11; and along pushing away the handle sliding tray to front slide; needle sleeve 11 is pushed away forward; promote until the front end of needle sleeve 11 exceeds the front end of syringe needle 12; the bell of needle sleeve 11 front ends can well protect the sharp place of syringe needle 12 front ends like this, can prevent effectively that syringe needle 12 from puncturing blood vessel and avoiding needle roller.
