[0002] A tumor is a tissue mass formed by abnormal cell proliferation, which may be benign (non-invasive and non-metastatic) or malignant (invasive and metastatic). Tumors are also known as masses, neoplasms or mass lesions. In the human body, cells are the basic units that make up various tissues and organs. Oncology nursing is a field of nursing designed specifically for the needs of cancer patients, which includes a series of medical and nursing activities aimed at providing comprehensive support and care for cancer patients. The purpose of oncology nursing is to improve the quality of life of patients and help them cope with the physical, emotional and social challenges during the cancer diagnosis and treatment process. In oncology nursing, a catheter fastening device is commonly used, and the general way to fasten the catheter is to use tape to fit with the catheter and then stick the tape on the patient's skin surface. After long-term use, the tape will lose its adhesiveness, and the fixed catheter will become loose, which may cause pain to the patient. Content of the Utility Model

Connecting blocks 2 are arranged on both sides of the fixing plate 1, and both connecting blocks 2 on both sides are fixedly connected to the fixing plate 1. One side of the fixing plate 1 is set as an arc, and a connecting component 3 is arranged on one side of the connecting block 2. The connecting component 3 includes a fixing belt 301, an adjusting belt 302, and an adhesive surface 303. There are two groups of fixing belts 301 and they are fixedly installed on one side of the connecting block 2. The adjusting belt 302 is slidably installed in the fixing belt 301, and the adjusting belt 302 can slide or be fixed in the fixing belt 301. The adhesive surfaces 303 are respectively arranged on the corresponding surfaces of the two groups of adjusting belts 302, and the two groups of adjusting belts 302 can be connected by relying on the adhesive surfaces 303. It also includes an adjusting mechanism 4. The adjusting mechanism 4 includes a limiting post 401, a moving groove 402, a spring 403, and a limiting groove 404. The moving groove 402 is opened in the adjusting belt 302. One side of the limiting post 401 is arranged in the moving groove 402 and is restricted from moving by the moving groove 402. One end of the spring 403 is fixedly connected to the bottom of the limiting post 401, and the other end of the spring 403 is fixedly installed on the inner wall of the moving groove 402. There are multiple groups of limiting grooves 404 and they are opened on the surface of the fixing belt 301 at equal intervals. The limiting post 401 can be inserted into the limiting groove 404, and the adjusting belt 302 can slide or be fixed in the fixing belt 301 by relying on the limiting post 401. The material of the fixing plate 1 is flexible, and a number of ventilation grooves 5 are also constructed in the fixing plate 1. Arrow marks 6 are also arranged on the surface of the fixing plate 1. There are two groups of arrow marks 6 and they are symmetrically engraved on the surface of the fixing plate 1.
