The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Fig. 1 is a schematic structural view of the balloon catheter and the retractable pressure balloon of the pulmonary circulation assistance device of the present invention, fig. 2 is a schematic structural view of the drug delivery tube of the pulmonary circulation assistance device of the present invention, please refer to fig. 1 to 2, which illustrate a preferred embodiment, an illustrated pulmonary circulation assistance device, comprising: the medical pressure balloon comprises a balloon catheter 1 and two retractable pressure balloons 2, wherein the two retractable pressure balloons 2 are arranged, one retractable pressure balloon 2 is fixed at the pulmonary artery through an anchoring device 4, the other retractable pressure balloon 2 is fixed at the axillary vein, the balloon catheter 1 is arranged between the two retractable pressure balloons 2, and the balloon catheter 1 is connected with the two retractable pressure balloons 2. The balloon catheter 1 is a double-lumen balloon catheter 1. The balloon catheter 1 is guided by a bedside heart super machine to place a pulmonary artery balloon in a compressed state into the pulmonary artery along a path of axillary vein-subclavian vein-superior vena cava-pulmonary artery. When the pulmonary artery contracts, the stent is placed at the pulmonary artery and anchored. When the pulmonary artery is relaxed, blood flows out of the right atrium, and the retractable pressure balloon 2 is transformed from the relaxed state to the contracted state, so that the pressure of the blood flow on the pulmonary artery is reduced. When the pulmonary artery contracts, the retractable pressure balloon 2 can provide reverse potential energy, so that blood can smoothly flow back. The two retractable pressure balloons 2 are correspondingly arranged, one retractable pressure balloon 2 at one side is in a compressed state, and the retractable pressure balloon 2 at the other side is in a full state. Anchoring device 4 includes support, spring and mount, and the support runs through the sacculus, and the both ends of support all are provided with a spring, and the one end that the support was kept away from to each spring all is provided with the mount. When one side of the saccule retracts, the other side of the saccule relaxes through the communicated catheter. The anchoring device 4 is conveyed to the pulmonary artery through a catheter, the spring is compressed by pressing the fixing frame through pressure in the transportation process, after the fixing frame is placed into the pulmonary artery, the pressure is removed, and the spring automatically resets through elasticity, so that the fixing frame is fixed at the pulmonary artery. The balloon anchoring device can be anchored in a pulmonary artery balloon relaxation state in the right ventricular circulation diastole so as to relieve the pressure of the right ventricle, and can provide reverse potential energy in the right ventricular circulation systole so as to increase the compliance of the pulmonary artery.
Further, as a preferred embodiment, the drug delivery device further comprises a drug delivery pipeline 3, the balloon catheter 1 is provided with the drug delivery pipeline 3, and the drug delivery pipeline 3 is adhered to the surface of the balloon catheter 1. One end of the drug delivery pipeline 3 is arranged at the axillary vein, and the other end of the drug delivery pipeline 3 is arranged in the pulmonary artery. The drug delivery pipeline 3 is arranged in a shower head shape at one end in the pulmonary artery. The drug delivery pipeline 3 is communicated with the body of the patient and the pulmonary artery, the drug can be put into the pulmonary artery of the patient from one end of the leaked drug delivery pipeline 3 and is arranged in a shower-shaped manner, and the spraying area of the drug can be increased. Traditional drugs (including targeted drug metabolism) need to directly reach the pulmonary artery through a drug delivery system through a first-pass effect, and the pulmonary artery compliance is improved. The pulmonary artery balloon anchoring device can be anchored in a pulmonary artery balloon relaxation state in the right ventricular circulation diastole to relieve the pressure of the right ventricle, and can provide reverse potential energy in the right ventricular circulation systole to increase the compliance of the pulmonary artery.
The above description is only an example of the preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and those skilled in the art should be able to realize the equivalent alternatives and obvious variations of the present invention.
