Description
Technical field
This utility model relates to a kind of central venous puncture device, and specifically a kind of sword bayonet type central venous puncture syringe, belong to the medical apparatus and instruments technical field.
Background technology
Along with the development of medical level, the application of central venous puncture technology is more and more extensive, is particularly useful for following situation: 1, various operation on vessels of heart under extracorporeal circulation; 2. hemodynamics variation Off-pump operation greatly will appear in estimation art; 3, the critical patients' such as severe trauma, shock and acute circulatory failure rescue; 4, need long-term high nutrition treatment or through the vein antibiotic therapy; 5, study some anesthetics or other treatment medication to the effect of blood circulation; 6, place interim or Permanent Cardiac Pacemakers through vein.
For some patient, whether the opening of venous channel has directly determined the meaning of rescuing, this just requires the opening of venous channel must accomplish accurately with rapid, and the central venous puncture tube indwelling technology is as the first-selected approach that solves this difficult problem, its operating technology complexity has determined the success or failure of this technology, and existing venipuncture apparatus often defines the breakthrough of technology, and this just proposes the innovation requirement to traditional puncture instrument.
The central venous puncture device is one of operating room essential items, plays vital effect at peri-operation period.At present central venous puncture is put pipe and must be undertaken by following five steps: 1 local anaesthesia fine needle is soundd out-2 coarse needle bioptics and is fixed-3 seal wires and insert-4 and expand that the skin devices expand that the dark venous ductes in skin-5 are inserted and fixing.At present the structure of central venous puncture device commonly used has caused being connected discontinuous in the 1-2-3 of piercing process step, and this 1-2-3 whether be connected smooth and easy be the key that determines the puncture success or failure just.The puncture failure common cause has: 1, fine needle is visited blood and is changed bodkin and visit failure again.For some patient, fine needle is visited blood vessel and originally is difficult for, and repeatedly puncture is not only wasted treatment time, and can bring misery to patient; Poor but must urgent puncture and intubation person for coagulation function, repeatedly puncture may cause the site of puncture hematoma, further increases venipuncture difficulty, even causes puncture failure and puncture related complication; 2 bodkins are visited venous blood, and blood back is also unobstructed, but when stretching the right hand by seal wire, bodkin further causes putting the seal wire failure because the singlehanded fixedly shakiness of left hand causes the bodkin shift in position, must again puncture.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sword bayonet type central venous puncture syringe is provided, and it is simple in structure, and is easy to operate during use, makes the traditional operation step more coherent, safe and reliable, is worthy of popularization.
The technical scheme that provides according to this utility model: sword bayonet type central venous puncture syringe, comprise syringe and be placed in the interior core body of syringe, it is characterized in that: described syringe front end is connected with hollow body, described hollow body is parallel with syringe, hollow body is inner to be connected by side connection tube and syringe are inner, and the internal diameter of described hollow body can make fine needle head and the seal wire of fine needle syringe pass through smoothly; Described hollow body front end is provided with for the sphenocephaly that connects thick needle, and hollow body rear end is provided with and penetrates mouth, and the fine needle head of fine needle syringe and seal wire can mouthful penetrate from penetrating.
As further improvement of the utility model, described side connection tube rear end is connected on needle cylinder wall, the oblique extension and being connected on the hollow pipe body wall forward of side connection tube front end.
As further improvement of the utility model, be provided with stiffener between described syringe, hollow body and side connection tube.
As further improvement of the utility model, described hollow body entrance is connected with check valve.
This utility model compared with prior art, advantage is:This utility model is with fine needle exploration, coarse needle bioptic and to insert seal wire integrated, avoid fine needle to sound out the situation of successful coarse needle bioptic failure, improved the stability of inserting the seal wire process, reduced the complexity of technology, save operation step and operating time, improve puncture success rate, reduce penetration damage and complication, this utility model is particularly useful for that anatomical structure is abnormal, fat, coagulation disorders and must accept puncture person.
