Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a medical perfusion device fixing auxiliary device. Background Art

[0002] At present, the medical perfusion fixing auxiliary device is a medical auxiliary instrument, which is mainly used to fix the perfusion device during surgery to ensure the smooth progress of the operation. The perfusion device often needs to be precisely fixed in a specific position during surgery to achieve the best surgical effect.

[0003] The utility model with authorization announcement number CN217219700U in the prior art is named: a perfusion device fixing device, which includes a base, a telescopic rod, a clamping mechanism and a connecting pipe fixing assembly, the clamping mechanism is detachably connected to the telescopic rod, the perfusion device clamping piece and the support plate are arranged on the mounting plate, the perfusion device clamping piece is used to fix the perfusion device, and the support plate arranged below the perfusion device clamping piece is used to support the perfusion device. This patent can enhance the stability of the perfusion device fixing and prevent the perfusion device from falling and affecting the work.

[0004] However, the perfusion device clamp in this patent is a rope with a buckle or a sticky block. Although the buckle design is simple, long-term use or frequent operation may cause the buckle to loosen or wear, thereby affecting its fixing effect. At the same time, the sticky block relies on sticky materials, but as time goes by and the number of uses increases, the sticky material may gradually lose its stickiness or be contaminated, causing the sticky block to fail and the clamping force to decrease, so there is a problem of unstable fixation.

[0005] The utility model with the authorization announcement number CN215134428U in the prior art is named as: a perfusion device fixing device, including a perfusion device fixing part and an auxiliary fixing piece, the perfusion device fixing part is used to fix the blood perfusion device, and the auxiliary fixing piece is connected to the external infusion stand to keep the perfusion device fixing device and the infusion stand relatively fixed. The patent is simple and convenient, and can realize the rapid fixation of the blood perfusion device. By fixing the blood perfusion device on the infusion stand, it is not only easy to operate, but also does not need to find an additional fixing part. During the dialysis process, the infusion stand is a common medical equipment, so the use of this design can easily maintain the stability of the perfusion device and improve the efficiency of medical work. In addition, the design of the perfusion device fixing part can adapt to different models of blood perfusion devices, ensuring that it is firmly fixed in the device to avoid shaking or displacement during use. The connection between the auxiliary fixing piece and the infusion stand also enhances the overall stability of the device, making it more reliable. In summary, the patent provides a simple, convenient and practical solution for fixing the blood perfusion device, and can be widely used in the medical field.

[0006] However, in this patent, the threaded rod is rotated by manually turning the nut-shaped switch to adjust the position of the abutting end, thereby completing the fixation and removal of the blood perfusion device. However, it is difficult to achieve precise adjustment through manual operation, which will cause deviations in the position or clamping force of the perfusion device, thereby affecting the fixation effect. Manual adjustment requires a certain amount of time and effort, especially in situations where multiple perfusion devices need to be processed quickly or in emergencies. The efficiency of this method is obviously insufficient, so there is a problem of unstable fixation. Utility Model Content
