Description

PICC arm encloses measuring device

Technical Field

The utility model relates to the technical field of medical equipment, a PICC arm encloses measuring device.

Background

Peripherally Inserted Central Catheter (PICC) refers to a Central venous Catheter Inserted Peripherally, with the Catheter being Inserted from the vein in the peripheral arm, and the Catheter reaching the great vein close to the heart. The device can greatly relieve the pain of repeated peripheral venipuncture of patients who are transfused for a long time, the central venous blood flow is fast, and the timely intake of various medicines and nutrient solutions and the smooth proceeding of chemotherapy are ensured. And the use is safe and reliable, so the medicine is widely applied clinically.

Nursing staff need measure and take notes patient's arm when carrying out postoperative care to the patient that has carried out PICC, and the arm that compares before the catheterization and behind the catheterization encloses the change, observes the arm swelling condition, and then judges whether there is complication such as inflammation to in time take measures to treat. At present, when a nursing staff measures the upper arm circumference of a patient, firstly, the patient bends the arm of the upper arm, the bent part inside the elbow of the patient is taken as a starting point, then, the upper arm circumference is measured upwards along the upper arm of the patient, a mark is made at a position 10cm away from the starting point, and finally, the upper arm circumference of the patient at the position of the mark is measured by a tape. The marks made by a pen are easy to disappear, so the steps are repeated when the upper arm circumference is measured every time, time and labor are wasted, the efficiency is low, and the error of the measuring method is large. On the other hand, the common flexible rule is too wide, reading is not easy, the flexible rule is easy to shift when winding the upper arm, and the flexible rule cannot be ensured to be wound on the circumference of the upper arm when winding the upper arm circumferentially, so that the measurement result error of the upper arm circumference is large.
