Description

Medical oncology PICC pipe cutting device

Technical Field

The utility model relates to an oncology technical field particularly, relates to an oncology PICC pipe cutting device.

Background

Tumor refers to a new organism formed by local tissue cell proliferation under the action of various tumorigenic factors, because the new organism mostly presents space-occupying block-shaped protrusions, which is also called neoplasm. It has been found that tumor cells exhibit metabolic changes that differ from normal cells, while tumor cells themselves can adapt to changes in the metabolic environment by switching between glycolysis and oxidative phosphorylation. The PICC tube is punctured from the vein of the peripheral arm by using a catheter, and the catheter directly enters the vein near the heart to avoid direct contact of chemotherapy drugs and the arm vein. With the rapid increase of venous blood flow, the chemotherapy drug can be diluted rapidly, and the stimulation of the drug to veins is prevented.

Intravenous chemotherapy is one of the main treatment methods for malignant tumor patients, and the patients are greatly suffered from local injuries caused by repeated venipuncture and drug extravasation. The PICC intubation is simple to operate, small in wound, safe and convenient, small in complication compared with other intubation, easy to accept by patients, capable of avoiding damage of the medicine to blood vessels and capable of improving life quality and nursing satisfaction of the patients.

At present, every PICC patient puts the pipe clinically, is about to the transfer line from the arm insert to internal, all will measure the puncture point and cut out the PICC pipe to the distance of one third below the right sternum joint, selects suitable length to put into. The patient is easy to insert into the right atrium after the patient is excessively measured; the short catheter is measured to be easy to enter other blood vessels, so that the medicine can not reach the designated position, and the curative effect is influenced. The PICC catheter is placed, after the supporting guide wire is pulled out, the length of the catheter needs to be trimmed, the catheter with the length of 6cm is left outside, and an inclined plane does not need to be cut.
