In some embodiments of the invention, when theair pump 21 inflates the balloon, the balloon begins to expand, compressing theblood vessel 4, and thus, the blood occlusion may be achieved.
As an implementation mode, theintelligent control unit 3 controls theair pump 21, and theair pump 21 inflates thespiral air bag 11 to block blood. Thepressure sensor 13 transmits the pressure value in real time, and when the pressure reaches a preset value, the blood is confirmed to be blocked, and theair pump 21 stops inflating. After the pressure is kept for a certain time (for example, 15 to 20 minutes), theintelligent control unit 3 controls theair pump 21 to deflate, and after the blood is kept not blocked for a certain time (for 5 to 10 minutes), the blood is blocked again. The above steps are repeated to achieve the effect of intermittent blood blocking until the operation is completely finished. Theintelligent control unit 3 carries out programmed setting, and carries out intermittent blocking on blood, thereby effectively reducing the necrosis of organs in the operation process.
According to the blood blocking device, theintelligent control unit 3 controls theair pump 21, theair pump 21 is started to inflate, the pressure value of blood is obtained in real time, and the blood flow condition is judged. Then, the operation of theair pump 21 is controlled to adjust the pressure of thespiral bladder 11 to a target value, and the blood is blocked. The pressure value is then maintained and the occlusion of the blood is performed for a period of time. Deflation then begins so that blood can circulate. The blood is then maintained for a period of time and the impedance of inflation is again performed. The above process is repeated until the operation is finished. The intelligent blood intermittent blocking method can ensure that the blood is completely blocked, prevent organs from being necrotic due to blood loss, reduce side effects and effectively ensure the success of the operation.
In summary, in the blood occlusion device of the present invention, the pressure value of thespiral balloon 11 is read to determine the blood occlusion condition, and the intelligent control system intermittently occludes the blood in the blood vessel, so as to achieve the purpose of intelligently controlling the blood occlusion, and reduce the workload.
