Detailed description of the invention
A kind of cardiovascular insertion type thrombolysis catheter having pressure sensitive of this utility model, include seal wire 1, medicine spraying tube 2, insecticide-spraying hole 3, suction bolt pipe 4, suction keyhole 5, frontal air bag 6, pressure sensitive circle 7, rear end air bag 8, support air bag 9, inflator pump 10, pressure display instrument 11, killer injecting pump 12, inhale bolt pump 13, fill sucking pump 14, injection preformed hole 15, described medicine spraying tube 2 is positioned at the outside of seal wire 1, medicine spraying tube 2 is provided with equally distributed insecticide-spraying hole 3, medicine spraying tube 2 is connected with suction bolt pipe 4 by insecticide-spraying hole 3; Described suction bolt pipe 4 is positioned at the outside of medicine spraying tube 2, inhales on bolt pipe 4 and is provided with equally distributed suction keyhole 5; Described suction keyhole 5 is spaced apart with insecticide-spraying hole 3; Described frontal air bag 6 is positioned at inhales the front end of bolt pipe 4 outside, and the front end of frontal air bag 6 inwall, middle part and rear end are provided with pressure sensitive circle 7; Described rear end air bag 8 is positioned at the rear end of inhaling bolt pipe 4 outside, and distance frontal air bag 63CM ~ 10CM place, the front end of rear end air bag 8 inwall is provided with pressure sensitive circle 7; Described support air bag 9 is positioned at the outside of inhaling bolt pipe 4; Described inflator pump 10 is fixedly connected with rear end air bag 8 with frontal air bag 6 by conduit; Described pressure display instrument 11 is connected with pressure sensitive circle 7 by wire; Described killer injecting pump 12 is fixedly connected with medicine spraying tube 2; Described suction bolt pump 13 is fixedly connected with suction bolt pipe 4; The described sucking pump 14 that fills is fixedly connected with support air bag 9; Described injection preformed hole 15 is positioned at medicine spraying tube 2 rear portion, and distance killer injecting pump 1210CM ~ 20CM.
The quantity of described insecticide-spraying hole 3 on same cross section is 4.
The quantity of described suction keyhole 5 on same cross section is 4.
Described pressure display instrument 11 shows the force value of 3 pressure sensitive circles 7 in frontal air bag 6 and the pressure sensitive circle 7 in rear end air bag 8 from top to bottom simultaneously.
Described injection preformed hole 15 has more than 3 and 3.
Seal wire 1, medicine spraying tube 2, insecticide-spraying hole 3, inhale bolt pipe 4, inhale keyhole 5, frontal air bag 6, pressure sensitive circle 7, rear end air bag 8, support air bag 9, inflator pump 10, pressure display instrument 11, killer injecting pump 12, inhale bolt pump 13, fill sucking pump 14, injection preformed hole 15,
Embodiment: first switched on power by pressure display instrument 11, inflator pump 10 gives frontal air bag 6 and rear end air bag 8 qi of chong channel ascending adversely, and 3 the pressure sensitive circles 7 arranged in frontal air bag 6 can move forward along with conduit and change numerical value.After lesions position, 3 pressure sensitive circle 7 registrations arranged in frontal air bag 6 are consistent substantially, show that frontal air bag 6 successfully crosses lesions position, accurately have found the blood vessel embolism point of blood vessel far-end.Thrombolytic drug is injected to medicine spraying tube 2 by injection preformed hole 15, open killer injecting pump 12 simultaneously, inhale bolt pump 13, fill sucking pump 14, the force value of the pressure sensitive circle 7 in monitoring rear end air bag 8, the pressure of fine setting killer injecting pump 12, suction bolt pump 13, the force value of the pressure sensitive circle 7 in rear end air bag 8 remains within the scope of blood vessel normal pressure value, if the force value that the pressure sensitive circle 7 namely in rear end air bag 8 demonstrates is excessive, then increase the pressure of the suction inhaling bolt pump 13 or reduction killer injecting pump 12; If if the force value that the pressure sensitive circle 7 in rear end air bag 8 demonstrates is too small, then reduce inhale the suction of bolt pump 13 or increase the pressure of killer injecting pump 12.Thrombolytic drug is injected in blood vessel by insecticide-spraying hole 3, and thrombosis fragment is inhaled into suction bolt pipe 4 by inhaling keyhole 5.The regular contraction of support air bag 9, utilizes the different of blood vessel and support air bag 9 contraction speed, make thrombolytic drug evenly fully with also make blood vessel produce the while of focal contact to vibrate more to be conducive to dropping of thrombosis fragment.The simultaneously supporting role of support air bag 9 makes the absorption of thrombosis fragment become to be more prone to, to improve the efficiency of thrombolytic.The utilization of pressure sensitive circle 7 effectively prevent the secondary injury to blood vessel.Simultaneously injection preformed hole 15 has more than 3 and 3 can be used for injection, also can when thrombolytic overlong time, and supplemental blood, effectively avoids the tissue ischemia overlong time of vascular embolization blood supply can cause necrosis thus lose the generation of the events such as therapeutic value.
