[0002] When changing PICC dressings or inserting medium-length catheters in the clinic, patients should try not to move their limbs during puncture and membrane replacement to avoid contamination, catheter displacement, dislocation or puncture failure, etc. However, patients' cooperation may not be very good in the clinic, especially in an aging society, where most patients are elderly and may not have caregivers. The elderly have poor cooperation due to their age, knowledge and comprehension ability, and muscle loss in their limbs due to illness or aging, so they need to hold up their limbs to fully expose the parts. This work often requires the assistance of a second person, who may be a family member, a caregiver or a nurse. However, in clinical operations, too many family members are not preferred to be around (because they are not professionals and may also cause contamination).
