Balloon guide catheter

The invention provides a balloon guide catheter, and in particular relates to the technical field of medical apparatus and instruments. The catheter is a composite pipe composed of an outer tube, an inner tube, and a suction tube positioned at the far end of the catheter which are coaxial, and a flexible balloon capable of realizing the full or contraction state is connected to the outer layer ofthe far end of the outer tube; an annular cavity between the inner tube and the outer tube forms a balloon filling cavity; the far end of the inner tube is welded to the near end of the suction tube;an inner cavity of the inner tube is connected with the inner cavity of the suction tube in series to form a guide cavity of the catheter, namely, a thrombus suction cavity; a main inner hole of a Y-shaped joint communicates with the inner cavity of the inner tube to form a wire guide cavity and the thrombus suction cavity; and the axis of side holes of the Y-shaped joint and the axis of the maininner hole of the Y-shaped joint have intersection at the near end direction of the catheter to form an acute angle, and the side holes of the Y-shaped joint and a gap between the outer wall of the inner tube and the inner wall of the outer tube communicate to form the balloon filling cavity. For the balloon guide catheter, during the interventional treatment process, blood flow can be blocked, sothat small broken thrombus is prevented from blocking the far end, and meanwhile, large thrombus blocks at the near end can be sucked, so that the surgery effect is greatly improved.

Spreading code synchronization method based on square correlation

The invention provides a spreading code synchronization method based on square correlation. The spreading code synchronization method based on square correlation comprises the following steps of: by use of the characteristics of an autocorrelation function of signals, modifying a spread spectrum signal and a local PN code sequence signal by virtue of square operation, respectively; performing correlation calculation on the modified spread spectrum signal and PN code sequence signal on the basis of sliding correlation dispreading; next, performing secondary threshold judgment on the obtained correlation value, and adjusting the phase shifting step length of the PN code according to the judgment result until a threshold condition is satisfied; and then realizing spreading code synchronization. According to the spreading code synchronization method based on square correlation, the square operation process is added to the signal processing process so that the influence of signal symbols on the correlation operation result is eliminated, the operation time is reduced and the synchronization efficiency is improved; a secondary threshold judgment and forward-reverse shifting module is added to reduce the times of shifting in the synchronization process, and as a result, the synchronization efficiency is further improved; besides, the synchronization accuracy can be guaranteed and the requirements of a communication system can be met.
