Description

Technical Field

[0001] The utility model relates to a disposable balloon-tipped triple-lumen perfusion tube, belonging to the technical field of extracorporeal circulation instruments in cardiothoracic surgery. Background Art

[0002] Due to congenital or acquired reasons, the aortic vascular wall loses its normal structure, and the elastic fiber layer that bears pressure and maintains arterial function becomes fragile. Under the impact of high-pressure blood flow, aortic aneurysm is likely to form; because the anatomical sites of various types of aortic aneurysms are different, the surgical and extracorporeal circulation perfusion methods are also different; currently, the mainstream method for treating this disease is surgical aortic arch replacement, which better solves the treatment problems of the aortic arch, but there are also problems such as more anastomotic sites during the operation, longer cardiac arrest time, and longer deep hypothermic circulatory arrest time. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a disposable balloon-tipped triple-lumen perfusion tube. The characteristics of the intubation of the utility model are as follows:

[0004] The tip of the intubation has side holes, which is beneficial to blood perfusion; the intubation has an inflatable balloon at the tip, which can be used for insertion and fixation as well as occlusion; the main body at the tail end of the intubation is connected to a one-way joint, and the main body of the intubation tube is triple-lumen with two branch tubes. One of the branch tubes, the front part of the balloon branch, is combined with the inside of the main body of the intubation tube and is connected to the balloon. The tail end part of the branch tube is connected to a medical three-way valve, and a medical syringe is connected to inject air or physiological saline to inflate the balloon. After the balloon is inflated, it does not affect the internal passage of the intubation; the other variable-diameter branch tube, the suction branch, is combined with the outside of the main body of the intubation tube. The front end is used for suction, and the tail end is connected to a 6×6 one-way joint, which can establish a connection with the extracorporeal circulation pipeline.

[0005] During surgical aortic arch replacement, the intubation of the utility model can be inserted after passing through the main body of the artificial blood vessel, and air or physiological saline is injected through the medical three-way valve to expand the balloon. After the balloon is expanded, it adheres tightly and seals. At this time, the aorta can be perfused through the main body of the intubation, and then the intubation is removed to continue with the suture and the next surgical operation.

[0006] Based on the above operation method, the intubation of the utility model is applied after surgical aortic arch replacement, which can significantly shorten the deep hypothermic circulatory arrest time during the suture process, reduce the incidence of postoperative complications of patients, and improve the quality of life.

[0015] For the convenience of understanding the embodiments, further explanatory descriptions will be made below in conjunction with [specific content not provided], and each embodiment does not constitute a limitation on the embodiments of the utility model.

[0016] Embodiment 1: As Figure 1 , Figure 2 , Figure 3As shown, the disposable balloon-tipped triple-lumen perfusion tube has an intubation tube body main body 1 with an intubation tip at the left side. There are side holes 4 at the intubation tip, and a balloon 5 at the intubation tip. The right side of the intubation tube body main body 1 is connected to the intubation tail end main body 2, and the tail end is connected to a 3 6×6 one-way joint. The intubation tube body main body 1 has three lumens and two branch tubes. The front part of the balloon branch tube 7 is combined with the inside of the intubation tube body main body and is connected to the balloon 5, and the tail end part of the balloon branch tube is connected to a medical three-way valve 10, and a medical syringe is connected to inject air or physiological saline for inflating the balloon. The other variable-diameter branch tube, the suction branch 8, is combined with the outside of the intubation tube body main body, with the front end for suction and the tail end connected to a 9 6×6 one-way joint.

[0017] Embodiment 2: As Figure 1 , Figure 2 , Figure 3 shown, the disposable balloon-tipped triple-lumen perfusion tube is composed of an intubation tube body main body 1, an intubation tail end main body 2, a one-way joint 3, a tip side hole 4, an inflatable balloon 5, a suction hole 6, a balloon branch 7, a suction branch 8, a one-way joint 9, and a medical three-way valve 10. The intubation tube body main body has various size specifications, including 10F, 12F, 14F, 16F, 18F, 20F and other specifications, which is beneficial for the selection of blood flow for clinical perfusion. The inflatable balloon can be fixed, with a large fitting area and obvious sealing effect. The medical three-way valve and the branch tube can be used to inflate or inject physiological saline and maintain the pressure of the balloon, facilitating the operation of the balloon. The one-way joint can be directly connected to the extracorporeal circulation pipeline. The tip side hole at the upper end of the balloon can be connected to the extracorporeal circulation pipeline for negative pressure suction.

[0018] The disposable balloon-tipped triple-lumen perfusion tube is applicable to surgical aortic arch replacement, achieving two functions: ① After the balloon is expanded, it adheres tightly to the inner cavity and seals, playing a fixing role to prevent the intubation from moving and blood leakage during perfusion, and at the same time providing an operable surgical field for suture; ② There is a tip side hole at the upper end of the balloon of the tube body main body, which can be used for negative pressure suction to clean the surgical field.
