[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0035] like Figures 1-2 As shown, a buckle device for fixing extracorporeal circulation tubing in cardiac surgery includes: a buckle body 1, the buckle body 1 including: a support plate 101, a protruding plate 102 provided on one side of the support plate 101, and a fixing tape 7 provided on the other side;

[0036] The protruding plate 102 is provided with a plurality of slots 2 on the side away from the support plate 101. The slots 2 are opened on the side away from the support plate 101, and a guide part 3 is provided at the opening of the slots 2.

[0037] The lower part of the slot 2 is provided with an installation groove 201, and a locking elastic piece 5 is provided on the installation groove 201. The locking elastic piece 5 is used to restrict the unidirectional pumping of the extracorporeal circulation tube.

[0038] The multi-layered structure of the support plate 101 and the extension plate 102 effectively supports and fixes the extracorporeal circulation tubing, ensuring its stable position during surgery. The fixing tape 7 on the support plate 101 facilitates the fixing of the buckle device, preventing the tubing from shifting due to external force or patient movement during surgery. The guide part 3 at the opening of the slot 2 helps medical staff to quickly and accurately embed the tubing into the slot, reducing installation time and improving surgical efficiency. One end of the extracorporeal circulation tubing is connected to the patient, and the other end is connected to external equipment. When the tubing is pulled away from the patient, it can easily cause injury. Therefore, the locking elastic piece 5 on the mounting slot 201 can limit the unidirectional movement of the tubing. This is especially important in extracorporeal circulation surgery, as it can prevent the tubing from being pulled away from the operating table due to unexpected factors, thus preventing unnecessary medical accidents.

[0039] Preferably, the area of ​​the support plate 101 is larger than that of the protruding plate 102. The fixing tape 7 is adhered to one side of the support plate 101. The fixing tape 7 is double-sided tape. When in use, the outer layer of the double-sided tape can be peeled off to stick the buckle device on the surgical towel or the side of the operating table, which facilitates the arrangement of the extracorporeal circulation tube.

[0040] like Figure 5As shown, the locking elastic sheet 5 comprises a mounting ring 501, an avoiding opening 502 is arranged on the mounting ring 501, the avoiding opening 502 is matched with the opening of the clamping groove 2, a plurality of clamping claws 503 are arranged on the inner wall of the mounting ring 501 at intervals, the clamping claws 503 are arranged obliquely towards the center of the mounting ring 501, and a rounded corner 504 is arranged at the end of the clamping claw 503.

[0041] By arranging the clamping claw 503 obliquely towards the center of the mounting ring 501, the design can provide better clamping force. When the extracorporeal circulation pipeline is inserted into the clamping groove 2, the clamping claw 503 will be opened due to the insertion of the pipeline. When the pipeline is pulled upwards, the moving direction of the pipeline is the same as the oblique direction of the clamping claw 503, and the clamping claw 503 does not affect the movement of the pipeline. When the pipeline is pulled downwards, the moving direction of the pipeline is opposite to the oblique direction of the clamping claw 503, and the clamping claw 503 bends towards the center with the movement of the pipeline, thereby clamping the pipeline and limiting the downward movement of the pipeline, which can effectively prevent personnel or objects outside the operating table from pulling the extracorporeal circulation pipeline.

[0042] When the medical staff needs to pull the pipeline downwards, the pipeline can be moved after being pulled out of the clamping groove 2. The arrangement of the guide part 3 can also facilitate the adjustment of the pipeline. Further, the arrangement of the rounded corner 504 can prevent the clamping claw 503 from scratching the outer wall of the pipeline. In specific use, the locking elastic sheet 5 is used to provide certain damping to the movement of the pipeline when the pipeline is pulled downwards, so as to prevent the pipeline from being pulled downwards quickly, and does not need to completely limit the downward pulling of the pipeline. Therefore, by arranging the rounded corner 504, the end of the clamping claw 503 is prevented from being embedded in the extracorporeal circulation pipeline, thereby preventing damage to the pipeline.

[0043] As shown in the figure, Figures 1-3 The inner wall of the clamping groove 2 is provided with a disinfecting cotton 4. By arranging the disinfecting cotton 4, disinfecting liquid can be added to disinfect the outer wall of the pipeline. The position of the surgical towel is a sterile area, and other positions may be non-sterile areas. Therefore, when the pipeline is pulled upwards, it may contaminate the sterile area. Therefore, by arranging the disinfecting cotton 4, the pipeline can be disinfected during the pulling process.

[0044] As shown in the figure, Figures 2-4 The protruding plate 102 is provided with a liquid supply assembly for supplying disinfecting liquid to the disinfecting cotton 4.

[0045] As shown in the figure, Figures 2-4 A plurality of flow guide holes 103 are arranged in the protruding plate 102, the flow guide holes 103 correspond to the clamping groove 2, one end of the flow guide hole 103 communicates with the clamping groove 2, and the other end penetrates the bearing plate 101.

[0046] The liquid supply assembly comprises a liquid storage tube 8 arranged inside the flow guide hole 103 and a pressing assembly 6 for interrupting the liquid storage tube 8. Through cooperation of the liquid storage tube 8 and the pressing assembly 6, the sterilizing liquid can be quickly supplied to the sterilizing cotton 4 without additional dropping by medical staff.

[0047] As shown in Figure 3 The flow guide hole 103 is provided with a limiting block 104 at one end adjacent to the clamping groove 2 and a blocking plug 9 at the other end, and the limiting block 104 cooperates with the blocking plug 9 to fix the liquid storage tube 8.

[0048] As shown in Figure 3 The middle part of the liquid storage tube 8 is provided with a necked part 801, and the pressing assembly 6 is used to interrupt the necked part 801.

[0049] As shown in Figure 3 The pressing assembly 6 comprises a fixed tube 601 arranged on the extension plate 102, and the lower end of the fixed tube 601 communicates with the flow guide hole 103, the middle part of the fixed tube 601 is slidably provided with a moving tube 602, the upper end of the moving tube 602 extends out of the fixed tube 601, and the lower end of the moving tube 602 is provided with a pressing block 603, and the lower end of the pressing block 603 abuts against the necked part 801.

[0050] In a specific embodiment, before pasting the clasp device, the medical staff presses the moving tube 602 to make the pressing block 603 interrupt the necked part 801 of the liquid storage tube 8, so that the sterilizing liquid in the liquid storage tube 8 flows out, then the clasp device is inclined to make the sterilizing liquid flow to the sterilizing cotton 4 and be soaked, then the outer layer of the fixed adhesive tape 7 is torn to paste the clasp device on the surgical towel or the operating table, and then the extracorporeal circulation pipeline is arranged.

[0051] In a specific embodiment, the extension plate 102 or the two sides of the bearing plate 101 can be provided with fixed clamps, when the clasp device needs to be fixed more firmly or is inconvenient to be pasted, the fixed clamps can be matched with external fixing positions.
