Abstract
Description
Technical Field
[0001] This utility model relates to the field of treatment beds, specifically a treatment bed with an arm fixator. Background Technology
[0002] Currently, the main function of clinical treatment beds is to provide patients with lying support, and their structure usually includes a bed board and support devices. However, in clinical scenarios such as tumor chemotherapy and long-term infusion, patients often need to undergo arm vein catheterization procedures (such as PICC, MC, arm port implantation, etc.). Such procedures require patients to keep their arms abducted at 90°-120° and strictly fixed to avoid puncture deviation or catheter displacement.
[0003] The existing treatment beds have the following significant defects: 1. Lack of dedicated fixation structure: When inserting a catheter into the arm, medical staff or caregivers need to manually maintain the patient's arm in an abducted position, which not only increases labor costs, but also easily leads to operator fatigue due to prolonged fixation, affecting the accuracy of the insertion; 2. Defects in temporary support devices: Clinically, temporary items such as treatment carts and soft cushions are commonly used to elevate the arm, which has the problem of poor stability of the support surface, causing the patient's arm to easily slide; 3. Lack of a structure for placing sterile items for operation, with limited functionality. Summary of the Invention
