technical field

The utility model relates to the field of medical devices, in particular to an intravascular balloon rapid hemostatic device.

Background technique

With the rapid development of medical technology, surgeons are faced with more and more complicated operations. During surgery, especially in thoracic surgery, emergent bleeding from large blood vessel tears has occurred from time to time. When the blood vessel bleeds heavily, rapid hemostasis is required, and then the torn blood vessel is sutured.

At present, the hemostasis of the torn blood vessel is usually to press the tear by hand, and then gradually separate the blood vessel until the root of the blood vessel is separated, and clamp the root of the blood vessel with vascular forceps, and then suture the tear. However, in this way, when pressing the tear, it is difficult to sew the tear synchronously, and there are operational contradictions. The operation of gradually separating the blood vessel and then repairing the blood vessel is not only time-consuming, but also easily causes secondary tearing of the blood vessel when separating the blood vessel.

After the suture is completed, the medical staff can slowly deflate the elastic airbag through the gas regulating mechanism, and the elastic airbag will shrink and decrease in volume after deflation. At this time, the suture effect of the blood vessel tear can be checked by checking whether there is blood oozing at the suture. When blood oozing occurs at the tear of the blood vessel, the elastic balloon can be inflated again to continue the vascular repair; When bleeding occurs again, the elastic air bag can be completely deflated, so that the elastic air bag is retracted back into the side hole of the puncture needle, and then the puncture needle is pulled out from the blood vessel to complete the rapid hemostasis of the blood vessel and the repair of the tear.

The puncture needle 4 and the airway 7 provided over the puncture needle 4 are inserted into the proximal end 1 (the right end in FIG. 1 ) of the blood vessel 14 where the rupture 2 has occurred. At this time, the needle handle 12 is pulled upward, and when blood returns in the needle barrel 3 of the empty needle, it proves that the puncture needle 4 has been punctured into the blood vessel 14 .

Since the elastic balloon 6 is accommodated in the air hole of the airway 7 , after the puncture needle 4 and the airway 7 are inserted into the blood vessel 14 together, the airway 7 will carry the elastic airbag 6 into the blood vessel 14 together. In addition, since the end of the airway tube 7 is provided with a tip whose inclination is consistent with the inclination of the needle tip of the puncture needle 4, the puncture of the airway tube 7 is facilitated. Then, the operator turns the three-way valve 8 to make the connecting tube 10 communicate with the airway tube 7, and then pushes the push handle 11 down along the needle tube 9. Since the push handle 11 is sealed and slidably connected to the needle tube 9, at this time the inside of the needle tube 9 Gas will be squeezed. The gas flows into the air tube 7 along the connecting pipe 10 and the three-way valve 8, and then flows into the elastic airbag 6 connected with the airway 7, and inflates the elastic airbag 6, so that the gas in the elastic airbag 6 increases and expands. Since the insertion position of the puncture needle 4 is the proximal end 1 of the blood vessel 14 , after the elastic balloon 6 is inflated, it will block the blood flow to the tear of the blood vessel 14 , cut off the blood flow path, and realize the rapid hemostasis of the tear blood vessel 14 .
