Description
Affiliated technical field
This utility model relates to a kind of Medical Instruments, particularly a kind of quick guiding deep vein puncture external member of being used for first aid little to tissue injury.
Background technology
At present, the deep vein puncture external member of usefulness is made up of syringe, special-purpose puncture needle, seal wire, dark venous duct, stitching thread, seam sword-shaped needle and scalpel etc. clinically.Finishing a deep vein puncture need be through 1. sterilization, 2. spread aseptic towel, 3. thin piercing needle is tried dark vein on, 4. 5. thick piercing needle puncture waits thick piercing needle pumpback behind a large amount of venous blood, promptly inserts seal wire from the syringe afterbody or the thick piercing needle survey opening of hollow, 6. move back thick piercing needle, insert dark venous duct along seal wire, 7. stitch skin, steps such as wrapping.Have following problem: 1, the puncture step is more, sets up dark venous channel when being unfavorable for first aid fast; 2, after thin puncture needle is soundd out dark vein, it need be extracted and re-use thick lancet puncture, can not well play guiding function.When using thick puncture needle to puncture for the second time, often, anatomical position or puncture pathway cause puncture failure because changing; 3, bigger to dark vein surrounding tissue damage during thick lancet puncture, penetrate tremulous pulse as careless mistake and can cause local hematoma, even the massive hemorrhage threat to life.
Summary of the invention
Various in order to overcome existing deep vein puncture assembly operation step, set up dark venous channel when being unfavorable for first aid fast, the deficiency that local damage is big.This utility model provides a kind of first aid with guiding the deep vein puncture external member fast, when using this puncturing kit that dark vein is carried out puncture and intubation, only need one-time puncture can finish dark Vein Tube, reduced operating procedure, and use thin puncture needle, smaller to dark vein surrounding tissue damage.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of deep vein puncture external member comprises: the long calparine cap of thin puncture needle, the venous duct that has the anti-flap valve that backflows and special use and special-purpose long transfusion adaptor.Described thin puncture needle comprises a tail end that is shaped as a side opening, the needle body at most advanced and sophisticated head end, the described most advanced and sophisticated 0.1～0.8mm of distance place and can connects syringe, the subapical side opening diameter of described thin puncture needle is 0.1mm～0.3mm, described thin puncture needle external diameter is 0.1mm～0.6mm, and the puncture needle outer wall has scale.The described venous duct that has the anti-flap valve that backflows comprises the tail end of the connect syringe of head end, venous duct body and a built-in anti-flap valve that backflows that is shaped as streamlined arc profile, the venous duct outer wall has scale, the venous duct head end also is most advanced and sophisticated, and the head end internal diameter is greater than described thin puncture needle needle body external diameter, described venous duct can be enclosed within described thin puncture needle outer wall, and can cooperatively interact with this thin puncture needle and be free to slide, described venous duct length is than the short 3～5cm of described thin puncture needle, and described venous duct material is a polyureas amine fat.The long calparine cap outward appearance of described special use is the hollow circuit cylinder body structure, the medical silica-gel plug and the tail end twist-lock structure that comprise head end, the special-purpose long calparine cap of described cylindrical structure center is an infusion channel, after the long calparine cap tail end of described special use twist-lock structure was connected with the venous duct tail end and screws, the long calparine cap infusion channel of described special use length was enough to surpass the anti-flap valve that backflows of the venous duct of the described anti-flap valve that backflows.Described special-purpose long transfusion adaptor outward appearance is the hollow circuit cylinder body structure, this hollow circular cylinder inwall is the twist-lock structure from head end to tail end, the center is an infusion channel, after described special-purpose long transfusion adaptor tail end twist-lock structure was connected with the venous duct tail end and screws, described special-purpose long transfusion adaptor infusion channel length was enough to surpass the anti-flap valve that backflows of the described flap valve venous duct of preventing backflowing.
The beneficial effects of the utility model are, deep vein puncture external member of the present utility model is different with the beveled needle point cutting vessel of the existing hollow of using always, its puncture needle is thin puncture needle, needle end is most advanced and sophisticated, puncture but between the blood vessel fiber, pass behind the passivity separating blood vessel, vein blood vessel puncture formed wound easily hemostasis and healing, and reduced when mistake penetrates tremulous pulse damage to arterial wall.Simultaneously, described thin puncture needle and described venous duct outer wall are provided with scale, judge depth of needle when being convenient to puncture.Described venous duct is enclosed within described thin puncture needle outer wall, after dark vein is thrust at thin puncture needle tip, venous duct can be sent into dark vein along thin puncture needle, because the venous duct tail end has the anti-flap valve that backflows, air can not enter vein via venous duct, and venous blood can not flow out from the venous duct tail end.Need not to re-use steps such as guide wire and expansion skin in the whole operation process, operation is obviously simplified, and sets up dark venous channel when being applicable to the emergency treatment first aid fast, and all very little to the arteriovenous damage in the piercing process.
