Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a hand support frame. Background Art

[0002] In clinical practice, the basilic vein is the first choice for forearm puncture for patients, including PICC catheter insertion and medium-long catheter insertion. During puncture, due to the anatomical position, the basilic vein is often biased to the inside of the patient's limb. During disinfection, the entire arm is abducted 90° and needs to be raised to at least 45° angle with the bed. The whole arm is suspended for 10-15 minutes to facilitate the disinfection of the entire arm on the puncture side. At this stage, a disinfection bracket is used clinically to help patients maintain the puncture position. Existing disinfection brackets have the following disadvantages: they are too bulky and large, and are not easy to store and carry; at present, the bracket only has a fixing function and cannot fine-tune the angle between the arm and the bed; at low temperatures, there is no heating function, which increases patient discomfort; the disinfection bracket fixes the forearm pad without distinguishing between different groups of people and only has a universal size, which is larger for women and obese people; the part that contacts the patient is not thoroughly disinfected, which is prone to cross infection and has low overall performance.

[0024] There are three buttons on the main switch 2 of the arm support frame, namely the main switch, the heating button, and the disinfection button. The first angle adjustment airbag 8 and the second angle adjustment airbag 6 are respectively provided on the left and right sides of the arm support 7. When the puncture angle needs to be adjusted, the corresponding airbag can be inflated. The rising of the airbag can change the angle between the arm fixing tunnel and the forearm. The function of the U-shaped arm fixing plate 4 is to preliminarily fix the patient's arm. The function of the arm fixing airbag 5 in the U-shaped arm fixing plate 4 is to cater to various arm sizes. The normal Asian or European arm is 20-35CM. The purpose of adding air is to better fix and fit the arm circumference of various types of people.
