Abstract
The utility model provides a blood blocking and drainage tube, which comprises an air charging pipe, an air chamber, a liquid feeding pipe and a hollow tube; wherein, the hollow tube is connected with the air chamber; the air charging pipe and the liquid feeding pipe are arranged outside the wall of the hollow tube; the hollow tube is used for transfusion and blood conduction. The utility model has reasonable design and structure, convenient operation, is exact so that an inferior vena cava above the liver cannot be exposed, saves operation time and reduces operative wound. The utility model can block the inferior vena cava above and below the liver, and guide the blood of the inferior vena cava into the right atrium at the same time, so that the blood stasis of the backflow tissue of the inferior vena cava can be reduced, the returned blood volume can be ensured, the amount of bleeding of liver operation can be greatly reduced and the security of the operation can be promoted.
Description
Affiliated field
This utility model belongs to bloodstream blocking and drainage tube, is mainly used in inferior caval bloodstream blocking, need block postcava when being applicable to operation on liver to reduce hemorrhage various occasions.
Background technology
At present, hemorrhage when reducing operation on liver often need be blocked Hepatic artery, portal vein and postcava simultaneously.Because the blocking-up postcava, venous return is obstructed, and the returned blood volume wretched insufficiency often causes serious hypotension and arrhythmia, even jeopardizes patient's life; It is bigger to expose liver superior and inferior vena cava operation technique difficulty, often causes big wound.
Summary of the invention
The purpose of this utility model provides a kind of blocking-up of tool blood flow and the pipeline of drain dual function, place it in postcava reaches blood flow by aerating gasbag blocking effect, reach the effect of blood drainage by intrinsic pipeline, thereby all deficiencies that cause when avoiding now blocking postcava clinically, for facility is created in operation, for the patient provides safe and effective therapeutic equipments.
This utility model is achieved through the following technical solutions: bloodstream blocking and drainage tube mainly comprise 2 gas tubes, 2 air bags, feed tube, hollow pipe, hollow pipe connects 2 air bags, 2 gas tubes and feed tube are arranged attached to outside the hollow tube wall, the leading portion that hollow pipe is positioned at air bag is a tube for transfusion, and the hollow pipe between 2 air bags is a drainage tube.The head end of tube for transfusion has infusion port, and there is 1 opening the tube for transfusion rear end near the air bag place.1 air bag of the corresponding feeding of the outlet of per 1 gas tube.The outlet of feed tube is parallel with hollow pipe tail end opening.
The utlity model has following characteristics: 1, reasonable in design, easy to operate, definite effect; 2, the present invention makes operation avoid exposing the liver superior and inferior vena cava, can save operating time and reduce operation wound; 3, the present invention promptly blocks on the liver postcava under the regulating liver-QI, simultaneously again the inferior caval blood flow of drain to right atrium, alleviate blood stasis and the effective returned blood volume of assurance that postcava refluxes and organizes, reduce the amount of bleeding of operation on liver greatly, improve the safety of operation.

The specific embodiment
This utility model will be further described in conjunction with the accompanying drawings.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.
Referring to accompanying drawing 1,2,3,4, bloodstream blocking and drainage tube mainly comprise gas tube 1, air bag 2, gas tube 3, air bag 4, feed tube 5, hollow pipe 12, hollow pipe 12 connects air bag 2 and air bag 4, gas tube 1, gas tube 3, feed tube 5 is arranged attached to outside hollow pipe 12 walls, the hollow pipe of air bag 2 leading portions is a tube for transfusion 7, hollow pipe between air bag 2 and the air bag 4 is a drainage tube 8, the head end of tube for transfusion 7 has infusion port 6, there is 1 opening 9 tube for transfusion 7 rear ends near air bag 2 places, transfusion is from infusion port 6 inputs in the art, flow through tube for transfusion 7 to 9 outputs of right atrium opening, the outlet of gas tube 1 feeds air bag 2, the outlet of gas tube 3 feeds air bag 4, and the outlet 11 of feed tube 5 is parallel with the tail end opening 10 of hollow pipe 12, and heparin saline splashes into by feed tube 5, to opening 11 outputs, being shaped as of air bag 2 is tubaeform, air bag 4 be shaped as tetragon, the head of gas tube 1 and gas tube 3 has the rubber spheroid.
Embodiment 2
Workflow of the present utility model is: sting right internal jugular vein until placing guide wire with commercially available internal jugular vein puncture free clothing, with venipuncture bag institute belt leather skin convergent divergent channel and skin expansion pipe 13 skin expansions and internal jugular vein, place trocar sheath 14 along guide wire and go into internal jugular vein and fix with suture needle.Connect infusion port 6 (Luer interface) with the 20ml syringe, tube chamber with injecting normal saline prefilled tube for transfusion 7 and drainage tube 8, then this utility model is put into 14Fr trocar sheath 14, when putting into about 20cm, connect gas tube 1 with the 10ml syringe, it is full to air bag 2 to charge into carbon dioxide, continues to advance this utility model until obvious resistance is arranged, lock bloodstream blocking of the present utility model and drainage tubes by trocar sheath 14, and take out the gas of most air bag 2.Touching infrahepatic vena cava or C arm machine by the surgical operation person takes the photograph sheet and determines bloodstream blocking and drainage tube position.Heparin saline splashes into by tube for transfusion 5, to 11 outputs of heparin pipeline tapping, mainly is to prevent the tube chamber blood coagulation.Transfusion is from infusion port 6 inputs in the art, and the tube for transfusion 7 of flowing through is to 9 outputs of right atrium opening.When operation needs the blocking-up postcava, connect gas tube 3 with the 10ml syringe, charge into carbon dioxide to air bag 4 comparatively full (can judge) by the inlet spheroid of gas tube 3, reuse 10ml syringe connects gas tube 1, charge into carbon dioxide to air bag 2 comparatively full (can judge), guaranteed not have the backflow of blood like this from hepatic vein by the inlet spheroid of gas tube 1.Inferior caval backflow blood arrives right atrium by tail end opening 10 drains to the right atrium opening 9 of hollow pipe 12.
