[0021] Example
[0022] See also Figures 1 to 4 In the embodiment of the utility model, a cannula holder comprises a fixing block 1, and an upper and a lower mounting frame 3 is arranged on the left outer wall of the fixing block 1, and a slide rail 4 is arranged above the mounting frame 3, and a slider 7 is slidably arranged on the slide rail 4, and two left and right clamping plates 5 are arranged on the slider 7, and a bidirectional screw 6 is rotatably arranged inside the mounting frame 3, and the bidirectional screw 6 passes through the slider 7 and is threadedly connected with the slider 7. At this time, rotating the bidirectional screw 6 can drive the left and right clamping plates 5 to move closer or farther. In actual use, when the Ecmo catheter needs to be fixed, the medical staff inserts the catheter into the mounting frame 3 and makes the Ecmo catheter move closer or farther. The Ecmo catheter is located between the left and right clamping plates 5. The bidirectional screw 6 can then be rotated to clamp and fix the Ecmo catheter using the clamping plate 5, which not only ensures the fixing quality of the device for the Ecmo catheter, but also can better meet the fixing requirements for Ecmo catheters of different sizes, thereby improving the applicability of the device to a certain extent. A rubber pad is also provided on the inner wall of the clamping plate 5. Under the action of the rubber pad, the Ecmo catheter can be protected, reducing the damage to the Ecmo catheter caused by the excessive hardness of the clamping plate 5, thereby ensuring the use quality of the Ecmo catheter.
[0023] A cavity is also provided inside the fixing block 1, and the bidirectional screw 6 penetrates the fixing block 1 and extends into the cavity. A worm wheel 8 is also provided on the bidirectional screw 6 located inside the cavity through a key connection. A worm 9 is also rotatably provided on the fixing block 1, and the worm 9 and the worm wheel 8 are meshed with each other. At this time, rotating the worm 9 can drive the bidirectional screw 6 to rotate through the worm wheel 8, thereby driving the clamping plate 5 to move, so that the clamping plate 5 clamps and fixes the Ecmo catheter. In addition, because the worm wheel 8 and the worm 9 have a self-locking function, the fixing quality of the clamping plate 5 for the Ecmo catheter is guaranteed. A rotary handle 10 is also provided at the top end of the worm 9, and the worm 9 can be driven to rotate by rotating the rotary handle 10, so that the clamping plate 5 is used to fix the Ecmo catheter.
[0024] The fixing block 1 is also provided with mounting blocks 11 on the upper and lower outer walls, and a strap 12 is provided on the mounting block 11. A connecting block 17 is provided at the end of the strap 12. A slide plate 15 is also slidably provided inside the mounting block 11, and an insertion rod 16 is provided on the right outer wall of the slide plate 15. A socket used in conjunction with the insertion rod 16 is provided on the connecting block 17. Under the action of the insertion rod 16 and the connecting block 17, the strap 12 can be disassembled, which makes it convenient for the staff to disassemble the strap 12, thereby making it convenient for the staff to replace the strap 12, thereby ensuring the installation quality of the device. A magic mother tape is provided on the upper strap 12, and a magic sub-tape is provided on the lower strap 12. Under the action of the magic mother tape and the magic sub-tape, the strap can be 12 is connected, so it is convenient to fix the device on the patient's head or leg, thereby ensuring the installation and fixing quality of the device, and at the same time it can better meet the use needs of different patients, thereby improving the applicability of the device. A support rod 19 is provided at the left end of the slide plate 15, and a spring 18 is provided at the outer end of the support rod 19. One end of the spring 18 is connected to the slide plate 15, and the other end of the spring 18 is connected to the inner wall of the cavity. At this time, under the action of the spring 18, the connection quality of the connecting block 17 and the mounting block 11 is guaranteed. A protective pad 13 is provided on the right outer wall of the fixing block 1. Under the action of the protective pad 13, the occurrence of damage to the patient due to the excessive hardness of the fixing block 1 is reduced, thereby improving the safety of the device when used.
[0025] In actual use, when the device is needed, the staff uses the strap 12, Velcro and Velcro to set the entire device on the patient's head or leg, so that the device meets the actual use needs. After that, the staff passes the Ecmo catheter through the installation frame 3 according to the actual use situation, and rotates the worm 9 to drive the bidirectional screw 6 to rotate through the worm gear 8, thereby driving the clamping plate 5 to move, so that the clamping plate 5 clamps and fixes the Ecmo catheter, thereby ensuring the quality of use of the Ecmo catheter. In addition, it can also meet the fixation requirements for Ecmo catheters of different sizes, thereby improving the applicability of the device. After the device has been used for a long time, the staff can push the slide plate 15 outward to make the insertion rod 16 release the restriction on the connecting block 17, thereby removing the strap 12, which facilitates the replacement of the strap 12, thereby ensuring the use efficiency of the strap 12.
