A kind of venous blood collection remaining needle that this utility model provides by special indwelling tube and bloodletting needle, can be realized blood sampling operation in the situation that not affecting medicinal liquid injection; Further optimize, adopt a plurality of medicine-pouring ports can realize multi-medicament simultaneously and inject; Further optimize, the flow that current limiter can limit medicinal liquid is set, and structure is smaller and more exquisite.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Structural representation when Fig. 1 is puncture of the present utility model.
Structural representation when Fig. 2 is blood sampling of the present utility model.
In figure: the first medicine-pouring port 1, the second medicine-pouring port 2, fluid sealant 3, flexible pipe 4, current limiter 5, base 6, indwelling tube 7, indwelling casing tube 8, sidewall opening 9, puncture needle 10, handle 11, bloodletting needle 12, leads blood pin 13, protective casing 14.
The specific embodiment
In Fig. 2, a kind of venous blood collection remaining needle, comprise remaining needle, the sidewall of indwelling tube 7 is communicated with injection portion by flexible pipe 4, in injection portion, be at least provided with a medicine-pouring port, the afterbody of indwelling tube 7 is provided with fluid sealant 3, and the head of indwelling tube 7 is provided with indwelling casing tube 8, bloodletting needle 12 stretches out from indwelling casing tube 8 through the fluid sealant 3 of indwelling tube 7 afterbodys, bloodletting needle 12 by flexible pipe 4 with lead blood pin 13 and be communicated with.During use, bloodletting needle 12 is inserted to the fluid sealant 3 of indwelling tube 7 afterbodys, and pass and enter vein blood vessel from indwelling casing tube 8, then will lead blood pin 13 and be connected and can realize blood sampling function with negative pressure storage blood vessel.Fluid sealant 3 adopts flexible medical silica-gel material, and after bloodletting needle 12 is extracted out, fluid sealant 3 can still be guaranteed sealing.This use is novel especially in the situation that implanting remaining needle, take a blood sample very convenient.
In Fig. 2, described bloodletting needle 12 afterbodys are also provided with the base 6 coordinating with indwelling tube 7 afterbodys, and base 6 is provided with handle 11.Structure, is convenient to grip thus.
Optimize as in Fig. 2, described medicine-pouring port is a plurality of, wherein at least one medicine-pouring port is provided with the lid with fluid sealant 3.Structure when injecting, can be injected multiple-medicinal-liquid simultaneously thus.In this example, can inject medicinal liquid from the first medicine-pouring port 1, the second medicine-pouring port 2 and indwelling tube 7 afterbodys simultaneously.Wherein, the second medicine-pouring port 2 can also be for injecting heparin anti-coagulating.
Optimize as in Fig. 1,2, on the flexible pipe 4 between indwelling tube 7 and injection portion, be also provided with current limiter 5.Structure thus, is convenient to regulate the flow of medicinal liquid.
Further optimize as in Fig. 1,2, described current limiter 5 slabbings, which is provided with wedge-shaped slot, one end of wedge-shaped slot major part is provided with peristome.By regulating flexible pipe 4 in the position of wedge-shaped slot, can control easily flow, delicate structure, easy to adjust.
Preferably, as in Fig. 1, be also provided with puncture needle 10, puncture needle 10 stretches out from indwelling casing tube 8 through the fluid sealant 3 of indwelling tube 7 afterbodys, and the afterbody of puncture needle 10 is provided with the base 6 coordinating with indwelling tube 7 afterbodys, and base 6 is provided with handle 11.Structure, is convenient to when implanting indwelling casing tube 8 thus, and puncture vein, after having punctured, takes out puncture needle 10.Can inject medicinal liquid, or blood sampling.If desired, also can be with bloodletting needle 12 as puncture needle.
Preferred as in Fig. 1,2, described indwelling casing tube 8 is flexible material, preferably adopts the flexible difficult material being bondd by blood, for example, contain composite or the supra polymer vinyl material of polytetrafluoro, adopt flexible material, avoid remaining needle because of the movable inwall that damages vein blood vessel of patient.The outer wall of the head end of indwelling casing tube 8 and puncture needle 10 and bloodletting needle 12 is sealed and matched, and the head end of preferred indwelling casing tube 8 adopts taper.Structure, is convenient to indwelling casing tube 8 along with puncture needle 10 or bloodletting needle 12 enter vein thus.
Preferred as in Fig. 1, described puncture needle 10 sidewalls are also provided with sidewall opening 9, and sidewall opening 9 is positioned at indwelling casing tube 8.Structure, avoids making the gas in indwelling casing tube 8 to discharge in piercing process thus.
Preferred as in Fig. 2; on described base 6, be also provided with protective casing 14; described protective casing 14 is provided with lateral opening, the part being connected with handle 11 with bloodletting needle 12 for holding puncture needle 10, and protective casing 14 moves along the axis of puncture needle 10 and bloodletting needle 12.More the structure of refinement is; front end at protective casing 14 is provided with stage, and the outer wall of this stage coordinates with the inwall of indwelling tube 7, also avoids protective casing 14 to be drawn out of completely simultaneously; the other end of corresponding protective casing 14 is also provided with stage, avoids protective casing 14 to be pulled out completely.Structure thus; when puncture needle 10 and bloodletting needle 12 penetrate after fluid sealant 3; syringe needle just can expose; and when puncture needle 10 and bloodletting needle 12 are extracted; protective casing 14 is spacing and do not move by indwelling tube 7, and puncture needle 10 and bloodletting needle 12 move, and protective casing 14 relatively moves with puncture needle 10 and bloodletting needle 12; needle point is covered, avoid hindering hands.The lateral opening arranging can also be for flexible pipe bending.
