Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, it relates to an auxiliary trolley for PICC catheter placement. Background Technology

[0002] PICC (Peripherally Inserted Central Catheter) placement, also known as peripherally inserted central catheter placement, provides a safe and effective infusion route for patients receiving long-term intravenous infusions, especially chemotherapy drugs. It is common in clinical chemotherapy patients and is a safe and effective placement technique. For PICC catheter placement in the arm, the patient needs to lie flat with their upper arm abducted 90 degrees and then raised 30-40 degrees for easy disinfection. The catheter is placed in a placement room or on the patient's bed. The height of the bed in the placement room differs from that in the ward, and some patients cannot lie flat and require a semi-recumbent position, necessitating changes in the height of the raised arm. When consulting with other departments for catheter placement, a large amount of equipment needs to be brought, including an electrocardiogram monitor, ultrasound machine, insertion kit, and disinfection supplies. Currently used four-wheeled trolleys lack storage racks for these instruments and are not suitable for placement under different bed heights and patient positions. During the placement process, the patient needs to lie flat... Lying down with the arm abducted to 90 degrees and then raised, the arm has no support point when raised, which makes the patient feel very tired. The arm is easily lowered due to lack of support, which can lead to contamination of the catheter insertion area. In addition, patients may experience varying degrees of discomfort due to their unfamiliarity with PICC catheterization. Patent No.: 202021335724.9 discloses an adjustable PICC catheterization auxiliary frame, which can fix the patient's arm during the PICC catheter insertion process and keep the patient's position from moving around randomly throughout the entire insertion process. However, its function is limited and cannot place the instruments required for catheterization. Therefore, a support frame to raise the wrist and provide the patient with some leverage is needed, as well as a shelf to place the instruments required for catheterization, suitable for PICC catheterization under the guidance of ultrasound or electrocardiogram instruments. Therefore, it is necessary to design a fully functional auxiliary trolley that can meet the needs of PICC catheterization. Summary of the Invention
