Description

Upper limb lifting frame

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an upper limb lifting frame.

Background

The PICC is placed in the central vein by peripheral venipuncture, and is punctured from the vein of the peripheral wrist by using a catheter, the catheter directly reaches the great vein close to the heart, so that the direct contact between a chemotherapeutic medicine and the vein of the wrist is avoided, and the blood flow speed of the great vein is very fast, so that the thinning therapeutic medicine can be quickly flushed, and the stimulation of the medicine to the blood vessel is prevented, thereby effectively relieving the pain caused by repeated venipuncture to a patient and ensuring the smooth treatment.

When PICC (peripherally inserted central catheter) sterilization puncture is performed on a wrist puncture point, a patient is required to lift the punctured wrist, hang and hold the upper limb and rotate the wrist by a certain angle, if the wrist of the patient sticks to the whole sterilization process by himself, the wrist of the patient is particularly tired, so that the pain of the patient is increased; when a patient with weak body or a patient who is not matched with the patient is encountered, an assistant is needed to assist in lifting the limbs of the patient, so that the labor cost is further increased, the operation of an operator can be influenced by the position of the assistant, and the disinfection operation is inconvenient.
