Description

Technical Field

[0001] The utility model relates to the technical field of medical machinery, in particular to a hemodialysis upper limb fixing frame. Background Art

[0002] During traditional dialysis, patients need to keep their arms still for a long time, which may cause muscle fatigue, discomfort and even pain. Therefore, the development of a device that can reliably fix the upper limbs and reduce discomfort has become an innovative need in the medical field. This device combines the precision design of mechanical engineering, ergonomic principles and medical safety standards, and is designed to provide stable and comfortable support while maintaining sufficient flexibility to adapt to the needs of different patients. By integrating advanced adjustment mechanisms, high-quality materials and easy-to-operate control systems, this fixation frame improves the overall experience of dialysis treatment, reduces the physical burden on patients, and improves the efficiency and safety of the dialysis process.

[0003] The prior art patent document No. CN209864804U discloses a hemodialysis upper limb fixing frame, comprising a mounting plate, a column is slidably mounted on the mounting plate, a slider is hingedly mounted on the lower end of the column, the slider is slidably connected to the mounting plate, and the column is fixedly provided with a vertical slide rail along the length direction. In the prior art, most of the patients do not have an upper limb fixing device when undergoing hemodialysis, and the patient's hands are easily shaken, and the patient's arms will be very cold if they are always exposed to the outside. When the utility model is in use, the column can be unfolded, the angle fixing buckle is used to make the column in a vertical state, and then the slider is slid to adjust the position of the column. After the position of the column is adjusted, the lifting slider can be slid to adjust the height of the movable rotating plate. When undergoing hemodialysis, the patient can put his arm in the U-shaped support glove, and then rotate the movable rotating plate to a suitable angle, cover it with a warm cloth and turn on the electric heating device to reduce the discomfort of the patient's hand.

[0004] However, the existing technology CN209864804U patent has a poor comfort of a hemodialysis upper limb fixation frame. In actual use, it can only provide height adjustment but cannot adjust the angle, which makes it impossible for the patient to adjust to a suitable angle, causing inconvenience to the user. At the same time, the material used in the hand contact part is relatively hard, and the patient's usage experience is not good. Utility Model Content
