Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a myocardial protection fluid infusion device. Background Technology

[0002] A myocardial protectant infusion device is a medical device used in cardiac surgery. Its main function is to infuse the myocardium with a special fluid during cardiac surgery to protect myocardial cells from damage such as ischemia and hypoxia.

[0003] Traditional myocardial protectant infusion devices are simple in structure and have a specific function. They are compatible with other commonly used cardiac surgery equipment such as cardiopulmonary bypass machines and cardiac monitoring devices, and are easy to connect and work together to complete various tasks in cardiac surgery. However, traditional myocardial protectant infusion devices require medical staff to manually adjust the concentration of the drug solution. This may lead to inaccurate drug dosage, causing the actual concentration of the myocardial protectant solution to deviate from the ideal concentration, thus affecting the myocardial protectant effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a myocardial protection fluid infusion device, which aims to improve the problem that traditional myocardial protection fluid infusion devices require medical staff to manually mix the drug concentration, resulting in inaccurate drug dosage and deviation in the concentration of the myocardial protection fluid, thus affecting the myocardial protection effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0027] Reference Figure 1 , Figure 2 and Figure 3The support assembly includes a fixed plate 2, the lower surface of which is fixedly connected to the upper surface of the control box 1. A collar 3 is fixedly connected to the outer wall of the fixed plate 2, and the inner wall of the collar 3 is fixedly connected to the outer wall of the storage tank 4. The transmission assembly includes a rotating ring 7, the inner wall of which is rotatably connected to the outer wall of the chassis 6.

[0028] Specifically, the fixing plate 2 and the collar 3 work together to fix the storage tank 4. Turning the handle 8 will cause the rotating ring 7 to rotate due to the fixing effect of the handle 8 and the rotating ring 7. The rotation of the rotating ring 7 will drive the first transmission arm 9 to rotate, and the rotation of the first transmission arm 9 will drive the fan blade 10 to rotate. When the myocardial protective fluid infusion device is not needed, the locking pin 11 is inserted into the inner wall of the chassis 6 to restrict the rotation of the first transmission arm 9, thereby achieving the effect of quickly dispensing myocardial protective fluid by controlling the opening and closing of the fan blade 10.

When the cross plate 16 rotates, it drives the first connecting column 17 to rotate. When the first connecting column 17 rotates, it drives the second transmission arm 18 to rotate. When the second transmission arm 18 rotates, it drives the second connecting column 19 to slide on the inner wall of the support frame 13. When the second connecting column 19 slides, it drives the clamping plate 20 to move, thereby achieving the effect of clamping the control box 1. Finally, this myocardial protection fluid infusion device can not only automatically mix the medicine by rotating the handle 8, but also clamp and fix the control box 1 by the clamping plate 20 to prevent the mixing ratio from deviating due to shaking during the mixing process.
