Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a PICC nursing bracket. Background Art

[0002] PICC (Peripherally Inserted Central Catheter) is a long, thin, flexible catheter that is inserted into a peripheral vein in the patient's arm and passes through the vascular system to reach the superior vena cava. Because the puncture point is in the peripheral vein, it has a wide vascular selectivity, a high success rate, less trauma, less chance of infection, reduces patient pain, and reduces vascular damage caused by repeated punctures, it is accepted by more and more patients.

[0003] Among them, a PICC care-specific bracket disclosed in application number CN202020476734.8 is also an increasingly mature technology, including a body, a groove is provided on the top of the body, a placement plate is provided inside the groove, a cylinder is vertically fixed below the placement plate, and the cylinder is transmission-connected to the placement plate. A support frame is also provided above the body, and the support frame is located on one side of the placement plate. The placement plate is transmission-connected to a lifting assembly. In the PICC care-specific bracket, medical staff only need to rotate the turntable through the lifting assembly, which improves the practicality of the PICC care-specific bracket.

[0004] A PICC nursing stand disclosed in CN201811413727.7 is also an increasingly mature technology. The patient's arm is placed on the sponge pad of the hand support plate, and then the upper ring is rotated and moved upward to pull the lifting rod upward, so that the stop block is clamped between the upper ring and the lower ring to fix the height of the lifting rod. The threaded height adjustment can be flexibly adjusted to any height to accommodate patients of different heights. The hand support plate supports the patient's arm, which solves the problem of patients raising their arms by themselves. Due to the long disinfection and drying operation time, the patient's arm cannot be stable. If the nurse cooperates to lift the patient's arm, it will waste manpower. The linear lifting height adjustment is not limited by space and saves space.
