Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a cardiac drainage tube device capable of reducing perioperative atrial fibrillation. Background Art

[0002] The incidence of atrial fibrillation (AF) after cardiac surgery is high, ranging from 15-40% after coronary artery bypass grafting (CABG) and as high as 37-50% after more complex heart valve surgeries. Several large retrospective studies have found that perioperative atrial fibrillation (PoAF) is an independent risk factor for poor long-term prognosis.

[0003] There are many factors that influence perioperative atrial fibrillation during cardiac surgery, primarily encompassing three categories: 1. High susceptibility to atrial fibrillation: factors such as a history of atrial fibrillation, advanced age, and atrial enlargement; 2. Procedure-induced factors: factors such as mitral valve surgery combined with superior or inferior vena cava cannulation, prolonged surgery, and pressure overload; and 3. Pericardial effusion / inflammation. With the exception of the third factor, the other two categories cannot be directly manipulated.

[0004] Postoperative PoAF most commonly occurs within three days of surgery, coinciding with the average duration of drainage tube placement. The rate of tube occlusion is approximately 36%. Blocked tubes significantly impair the drainage of pericardial effusions, leading to increased pericardial pressure and blood clots, which in turn significantly increase the release of inflammatory factors and, consequently, the incidence of PoAF.

[0005] Currently used drainage tubes are rubber tubes with side holes, which have a high clogging rate of up to 36%. To clear clots from these tubes, surgeons often use a "milking maneuver" to manipulate the tubes, attempting to draw out clots by artificially creating negative pressure. However, this method can increase cardiac damage from the side holes and is clearly not recommended by guidelines. A specialized drainage tube with a wire cleaning device has been designed. This design allows for the removal of clots by pulling the wire when the tube becomes clogged. This design demonstrated statistically significant results in a prospective cohort study (PoAF rates were 31% and 38% in the experimental and control groups, respectively). Despite this statistical difference, PoAF remains clinically significant in both groups. Furthermore, this finding has not been replicated in randomized controlled studies and is considered to increase medical costs and socioeconomic burden. Utility Model Content

[0016] (2) By setting up a pressure sensor, the pressure of the flushing fluid at the end of the flushing tube can be detected in real time to prevent pericardial effusion caused by the flushing speed being higher than the drainage speed.

[0017] (3) Different storage chambers can store different compositions of flushing fluids to meet different flushing needs.

The inner diameter of the irrigation tube 2 is smaller than the outer diameter of the drainage tube 1. The irrigation tube 2 comprises a first section 2a and a second section 2b. The first section 2a is nested within the drainage tube 1, while the second section 2b is located outside the drainage tube 1. The second section 2b is connected to the medical pressurizer 4 and the heater 3. The irrigation tube 2 is used to inject irrigation fluid into the human body, while the drainage tube 1 is used to remove waste fluid after irrigation. The heater 3 can be a commercially available pre-made medical infusion heater. This product can be purchased and used directly. This application does not involve improvements to the heater structure. Therefore, the internal structure and operating principle of the heater will not be described in detail here. The medical pressurizer 4 can be a commercially available small infusion pump. This product can be purchased and used directly. This application does not involve improvements to the medical pressurizer structure. Therefore, the internal structure and operating principle of the medical pressurizer will not be described in detail here. The heater heats the irrigation fluid to a set temperature to minimize discomfort caused by temperature differences. Nesting the drainage tube and irrigation tube allows for integrated implantation, meaning the irrigation tube can be implanted simultaneously with the drainage tube, reducing the complexity and complexity of the procedure.

[0025] Preferably, a pressure sensor 5 is provided within the irrigation tube 2. The pressure sensor 5 can be a commercially available medical pressure sensor. It can detect the pressure of the irrigation fluid at the end of the irrigation tube 2 in real time, preventing pericardial effusion caused by irrigation rates exceeding drainage rates. The inner wall of the irrigation tube 2 can be provided with a slot for securing the pressure sensor. An insulated wire can be provided within the irrigation tube 2 to connect the pressure sensor 5 to an external computer or other information processing device.

The irrigation fluid tank 6 can be shaped like a hollow cylinder, with the multiple storage chambers 7 arranged circumferentially around the tank. The one-way valve 9 can be a diaphragm-type one-way valve, commonly available in the art, that automatically opens or closes based on a pressure differential across the chamber. Different storage chambers 7 can store irrigation fluids of varying compositions, thereby meeting varying irrigation needs.

[0027] Preferably, a rotating disk 10 is rotatably provided at the bottom of the flushing liquid tank 6, and a liquid guide port 11 is provided on the rotating disk 10.
