Embodiment 1

[0037] Such as figure 1 As shown, an intelligent control device for interventional catheter aspiration and thrombectomy includes a valve 1, a proximal tube 2, a distal tube 3, a controller 4, a pressure sensor 5, and a switch 6; the controller 4 adopts a commercially available PLC controller, or MCU microcontroller.

[0038] The proximal end of the valve 1 is connected to the proximal pipe 2, the water inlet 201 at the proximal end of the proximal pipe 2 is connected to the suction catheter 8, the distal end of the valve 1 is connected to the distal pipe 3, and the water outlet 301 at the distal end of the distal pipe 3 is connected to the suction pressure Source (not shown in the figure) connection;

[0039] In the existing structure, the suction conduit 8 is directly connected to the suction pressure source, and the degree of opening and closing of the suction conduit 8 and the suction frequency cannot be adjusted.

[0040] The controller 4 is electrically connected to the...

Embodiment 2

[0063] An intelligent control device for interventional catheter aspiration and thrombectomy, the switch adopts an XYZ three-position switch, and the other structures are the same as those in Embodiment 1.

[0064] Such as Figure 4 As shown, a control method for an intelligent control device for interventional catheter aspiration and thrombectomy, comprising the following steps:

[0065] (1) power on, when controller 4 is required to work, power on controller 4 by power supply 7, and enter the (2) step; when controller 4 is not required to work, disconnect power supply 7 and end;

[0066] (2) The valve 1 is reset, and the controller 4 controls the valve 1 to reset to the initial closed state (indicator light state 1), and enters step (3);

[0067] (3) The switch 6 is controlled. The operator toggles the switch 6 according to the needs. The switch 6 adopts the XYZ three-position switch. When suction is required, the switch 6 is toggled to the automatic gear (X gear), that is,...

Abstract

The invention discloses an intelligent control device and a control method for interventional catheter suction thrombectomy, and belongs to the technical field of interventional blood vessel thrombectomy. The device comprises a valve, a near-end tube, a far-end tube, a controller, a pressure sensor and a switch; the near end of the valve is connected with thenear-end tube, a water inlet at the near end of the near-end tube is connected with a suction catheter, the far end of the valve is connected with the far-end tube, and a water outlet at the far end of the far-end tube is connected with a suction pressure source; the controller is electrically connected with the pressure sensor, the pressure sensor is installed on the near-end tube, and the controller is electrically connected with a power source used for supplying power and the switch used for mode switching. The blood loss of a patient is reduced by controlling the opening and closing degree of the valve during suction, a doctor is enabled to judge whether the near end of a catheter is in contact with obstructions or not in real time through detection and feedback, the removal rate of the obstructions such as thrombus is increased, according to the control device and the control method, the doctor has more energy to pay attention to the conditions of the patient, and the operation safety is improved.

Description

technical field [0001] The invention relates to an intelligent control device and control method for interventional catheter aspiration thrombectomy, belonging to the technical field of interventional blood vessel thrombus removal. Background technique [0002] Vascular embolism refers to the blockage of the lumen of the blood vessel after thrombus, embolus or plaque falls off, resulting in the impediment of blood flow, adversely affecting the patient's physical function, and in severe cases, threatening the safety of life. [0003] At present, clinically, the suction catheter is mainly used to remove the thrombus and other obstructions that affect the patency of the blood vessels. The suction catheter is used to remove: under the guidance of digital silhouette angiography (DSA) and other equipment, the proximal end of the suction catheter is placed on the thrombus. At one end of the blockage, negative pressure is provided by a pressure source such as a large-capacity syring...
