Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a fastening mechanism and an upper limb raising device. Background Art
[0002] Hematological tumors are highly heterogeneous diseases originating from hematopoietic organs, characterized by high malignancy, complex treatment, and a lengthy course of disease. Hematological tumors mostly rely on intravenous infusion of chemotherapy drugs to kill tumor cells. Peripherally inserted central catheters (PICCs) are a common catheter insertion method that can reduce the stimulation caused by drugs and avoid the physical and psychological discomfort caused by repeated punctures to patients. Therefore, they are often used for chemotherapy in patients with hematological tumors. The American Intravenous Infusion Standards and the Chinese Intravenous Infusion Professional Standards both recommend PICCs as the preferred venous access for patients with long-term intravenous infusions and infusions of vascular irritating drugs.
[0003] PICC is preferably inserted into the vein of the upper limb. Clinically, it can be inserted through the basilic vein, median cubital vein or cephalic vein of the upper limb. To prevent the formation of venous thrombosis after catheterization, it is often necessary to raise the arm on the catheterized side. Literature shows that raising the affected limb by 30° can better promote venous return and eliminate swelling. The existing upper limb lifting pad lacks fixation for the patient's upper limb. When used at night, the patient's limbs often move after falling asleep, causing secondary injuries. In addition, the existing lifting pad often uses pillows or quilts to complete the lifting of the affected limb, which results in insufficient height and angle, and the affected limb cannot be completely lifted and the joint cannot be in a functional position. Based on the above problems, we proposed a fastening mechanism and an upper limb lifting device. Utility Model Content
