Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of blood internal medicine puncture needle。
Background technology
Current PICC is the important means that the hematopathys such as leukemia need long term injections chemotherapy, PICC and peripherally inserted central catheter, mainly by peripheral vein (basilic vein, median cubital vein, cephalic vein) puncture cannula, catheter tip is made to be positioned at superior vena cava, in providing for patient, long-term infusion, puncturing operation commonly uses lacerable cannula sheath, existing frequently-used tearable cannula sheath does not have and anti-error tears function, and tearable groove is provided with two squeezing handles at sheath cap portion, as the power strong point in inserting needle process, the situation that easy generation is torn by mistake, thus place into conduit to puncture and cause difficulty；And when tearing, two squeezing handles are outwards broken, produce tear edge, and the bottom of squeezing handle can produce inside extruding force, and the conduit in cannula sheath is damaged。
Summary of the invention
For overcoming described deficiency, the purpose of this utility model is in that to provide a kind of blood internal medicine puncture needle, easy to use, can guarantee that steady inserting needle, and can be prevented effectively from cross infection, and can effectively prevent from tearing by mistake。
This utility model solves its technical problem and be the technical scheme is that a kind of blood internal medicine puncture needle, including cannula sheath, puncture needle, described puncture needle includes needle body, base, one end of needle body is provided with base, chassis outer side is provided with needle handle, needle handle is provided with postive stop baffle near needle body place, it is provided with cannula sheath outside described needle body, described cannula sheath is near one end of needle body base, it is arranged with pull handle one, pull handle two, wherein pull handle one connects nylon wire, nylon wire is perpendicular to the cross section of cannula sheath, described cannula sheath is positioned at pull handle one, pull handle two one end is externally provided with circular cutting ferrule。
Further, described pull handle one, pull handle two outwards turn down 180 degree, are attached to circular card and put。
Further, on described cannula sheath, corresponding nylon wire position is provided with through the tearing groove at two ends。
Further, described pull handle one, pull handle two are provided with compression sterilized cotton piece, it is prevented that cause iatrogenic pollution to conduit or seal wire when tearing removal cannula sheath。
This utility model has the advantages that simple in construction, end are provided with needle handle, convenient use, can guarantee that steady inserting needle；The process of Preoperative Method and inserting needle is total, the hands of limited location baffle operator, it is prevented that casual to cannula sheath applying pressure, can effectively prevent cannula sheath from tearing by mistake, and when needs are torn, pulling pull handle one, pull handle two, pull handle one is motionless, pull handle two draws nylon wire, producing local pulling force, make cannula sheath easily tear, the process torn is that end outwards pulls, internal conduit will not be produced extruding force, it is prevented that conduit is damaged；Circular cutting ferrule, its effect one is protection cannula sheath, it is prevented that tearing, two is clamping cannula sheath and base by mistake, it is prevented that inserting needle process middle sleeve sheath loosens；Cotton piece can be compressed when can prevent cannula sheath from tearing, operator's hand contact conduit or seal wire, pollute, can effectively prevent cross infection。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Fig. 2 is the partial enlarged drawing of a pull handle of the present utility model part。
In figure, 1 puncture needle, 11 needle bodies, 12 bases, 13 needle handles, 14 postive stop baffles, 2 cannula sheaths, 21 pull handles two, 22 pull handles one, 23 nylon wires, 24 circular cutting ferrules, 25 compression sterilized cotton pieces,
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail。
According to Fig. 1, a kind of blood internal medicine puncture needle shown in Fig. 2, including cannula sheath 2, puncture needle 1, described puncture needle 1 includes needle body 11, base 12, one end of needle body 11 is provided with base 12, needle handle 13 it is provided with outside base 12, needle handle 13 is provided with postive stop baffle 14 near needle body 11 place, it is provided with cannula sheath 2 outside described needle body 11, described cannula sheath 2 is near one end of needle body 11 base 12, it is arranged with pull handle 1, pull handle 2 21, wherein pull handle 1 connects nylon wire 23, nylon wire 23 is perpendicular to the cross section of cannula sheath 2, described cannula sheath 2 is positioned at pull handle 1, pull handle 2 21 one end is externally provided with circular cutting ferrule 24, its effect one is protection cannula sheath 2, prevent from tearing by mistake, two is clamping cannula sheath 2 and base 12, prevent inserting needle process middle sleeve sheath 2 from loosening。
Further, described pull handle 1, pull handle 2 21 outwards turnover 180 degree, it is attached to circular 24 cards and puts。
Further, on described cannula sheath 2, corresponding nylon wire 23 position is provided with through the tearing groove at two ends。
Further, described pull handle 1, pull handle 2 21 are provided with compression sterilized cotton piece 25, it is prevented that cause iatrogenic pollution to conduit or seal wire when tearing removal cannula sheath 2。
