Description

Technical Field

[0001] The utility model relates to the field of medical equipment, and more specifically to a cardioplegia solution perfusion pipeline for extracorporeal circulation in cardiac surgery. Background Art

[0002] In the human body, the main function of the heart is to provide power for blood flow and to circulate blood to all parts of the body. In major hospitals, cardiac surgery is a department that treats various types of cardiac surgeries such as cardiac trauma, cardiac pacing, and heart-lung transplantation. When performing heart surgery, it is necessary to infuse cardioplegia into the heart to protect the patient's stopped heart. When infusing cardioplegia, a special infusion line is required.

[0003] Existing perfusion pipelines are usually stored in a box filled with foam plastic after production. Although the foam plastic box can provide overall protection for the perfusion pipelines, if the box is opened, a single perfusion pipeline will be impacted during taking and placing, which will still cause damage to the perfusion pipeline. In the subsequent treatment process, serious medical accidents may easily occur, posing a safety hazard.

[0004] Therefore, in view of the above problems, a cardioplegia solution perfusion circuit for extracorporeal circulation in cardiac surgery is proposed. Utility Model Content

[0028] Example:

[0029] See also Figure 1 - Figure 4A cardioplegia fluid perfusion circuit for extracorporeal circulation in cardiac surgery comprises a perfusion pipeline 1. A protective mechanism is arranged on the outside of the perfusion pipeline 1. The protective mechanism comprises a first protective component and a second protective component which are symmetrically arranged. The first protective component comprises an inner sheet 2 attached to the outer surface of the perfusion pipeline 1, and a first outer plate 6 is arranged on the side of the inner sheet 2 away from the perfusion pipeline 1. The second protective component comprises an inner sheet 3 attached to the outer surface of the perfusion pipeline 1 away from the inner sheet 2, and a second outer plate 7 is arranged on the side of the inner sheet 3 away from the perfusion pipeline 1.

[0030] Specifically, the outer surfaces of the first inner plate 2 and the second inner plate 3 are fixedly connected with a plurality of telescopic rods 5 , and the outer parts of the plurality of telescopic rods 5 are sleeved with springs 4 .

[0031] Specifically, the first inner plate 2 is fixedly connected to the first outer plate 6 via a telescopic rod 5 disposed thereon, and the second inner plate 3 is fixedly connected to the second outer plate 7 via a telescopic rod 5 disposed thereon.

[0032] In this solution, the No. 1 inner plate 2 and the No. 2 inner plate 3 are symmetrically arranged, the No. 1 outer plate 6 and the No. 2 outer plate 7 are symmetrically arranged, the outer sides of the No. 1 outer plate 6 and the No. 2 outer plate 7 are both sponges, and the inner sides are both plastic plates. The spring 4 is used to buffer the impact force outside the perfusion pipe 1, and the telescopic rod 5 plays a guiding role for the spring 4 to prevent the No. 1 inner plate 2 and the No. 1 outer plate 6, the No. 2 inner plate 3 and the No. 2 outer plate 7 from being misaligned after the spring 4 is impacted.

[0033] See also Figure 1 - Figure 4 A first connecting component is provided on the side of the No. 1 inner plate 2 close to the No. 2 inner plate 3, and the first connecting component includes a No. 1 mounting plate 8 fixedly connected to the side of the No. 1 inner plate 2 close to the No. 2 inner plate 3; a second connecting component is provided on the side of the No. 2 inner plate 3 close to the No. 1 inner plate 2, and the second connecting component includes a No. 2 mounting plate 10 fixedly connected to the side of the No. 2 inner plate 3 close to the No. 1 inner plate 2.

[0034] Specifically, a through slot 81 is formed through one side of the No. 1 mounting plate 8 , and a clamping column 9 is fixedly connected inside the through slot 81 .

[0035] Specifically, a No. 2 through slot 101 is formed on one side of the No. 2 mounting plate 10, a rotating buckle 11 is rotatably connected to the inside of the No. 2 through slot 101, a yielding slot 102 is formed on one side of the slot wall of the No. 2 through slot 101, and one side of the rotating buckle 11 is arranged inside the yielding slot 102.

[0036] Specifically, the rotating buckle 11 is engaged with the clamping column 9 .

[0037] In the present solution, the cooperation between the rotating buckle 11 and the clamping column 9 can fix the No. 1 mounting plate 8 and the No. 2 mounting plate 10, thereby connecting the first protective component and the second protective component, and installing the protective mechanism on the perfusion pipe 1. The size of the yield groove 102 is larger than the size of the rotating buckle 11, which is convenient for the staff to manually depress the rotating buckle 11. Through the cooperation between the first connecting component and the second connecting component, the disassembly and assembly of the first protective component and the second protective component can be facilitated. When the perfusion pipe 1 needs to be used, the protective mechanism can be quickly removed. At the same time, it can also facilitate the staff to install different numbers of protective mechanisms according to the perfusion pipes 1 of different lengths, thereby improving the flexibility of the device.

[0038] Working principle: before storing the perfusion pipe 1, the staff first places the first protection component and the second protection component on both sides of the perfusion pipe 1 respectively, and then presses the rotating buckle 11 into the clearance groove 102 by hand, and then moves the first protection component and the second protection component closer to the perfusion pipe 1 until it is clamped, and finally releases the rotating buckle 11 to make the rotating buckle 11 engage with the clamping column 9, and the installation of the protection mechanism is completed. When the perfusion pipe 1 is impacted by external force during storage and transportation, the spring 4 will offset the external force and protect the perfusion pipe 1;

[0039] When using the perfusion pipe 1, the medical staff manually presses the rotating buckle 11 into the clearance groove 102, and separates the first protection component from the second protection component for normal use.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
