Description

Adult uses PICC to put pipe arm branch and beats mount

Technical Field

The invention relates to the field of PICC (peripherally inserted central catheter) arm fixing equipment, in particular to a PICC arm support pulsation fixing frame for adults.

Background

The central venous catheterization through peripheral venipuncture is realized by utilizing a catheter to puncture from a vein of a peripheral arm, the catheter directly reaches a great vein close to a heart, the direct contact between chemotherapy drugs and the vein of the arm is avoided, and the blood flow speed of the great vein is high, so that the chemotherapy drugs can be quickly diluted, and the stimulation of the drugs to blood vessels is prevented; therefore, the upper limb vein can be effectively protected, the occurrence of phlebitis is reduced, the pain of a patient is relieved, and the life quality of the patient is improved; along with the rapid development of medical technology, the application range of PICC catheterization is also expanding constantly to innovate and design the fixing device who uses when putting the puncture of tub arm to PICC, play the effect of promoting to medical technology's development.

Because the existing arm fixing device for PICC (peripherally inserted central catheter) catheterization puncture cannot adjust the placement area of a fat arm or a thin arm, the automatic clamping and fixing of the arm are realized, the fat arm or the thin arm and the clamping piece are tightly or loosely attached, the arm of a patient cannot be improperly fixed or not firmly attached, and the angle of the arm can be adjusted on the premise that the clamping piece is opened by medical personnel or the patient manually, the exposed blood vessel of the arm to be punctured is complicated, the PICC catheterization puncture is long in time consumption and low in efficiency due to the fact that the existing arm fixing device cannot finely adjust the angle of the fixed arm, and therefore an adult needs to develop and use the PICC catheterization arm support fixing frame urgently.

3. Advantageous effects

The arrangement of the arc-shaped surface structure of the connecting plate enables the connecting plate to locally extrude and fix the placed arm, thereby avoiding inconvenience for the puncture work of the fixed arm due to the large replacement contact area of the fixed arm and the fixing device.

The invention finely adjusts the angle of the arm contacted above the first sleeve by the rotation of the fixed rod, thereby exposing the position of the arm to be punctured, providing convenience for the puncture work of medical personnel, avoiding the contact between the existing medical personnel and the punctured arm, and adjusting the position of the arm for multiple times during puncturing, thereby causing the problems of long puncturing time and low efficiency of a PICC catheter, and elastically supporting the arm placed above the first sleeve by the deformation generated by the first rubber pad, thereby providing a comfortable experience environment for the punctured arm, further reducing the influence on the comfortable degree of the arm due to the contact between the arm and the fixed plate surface for a long time to a certain extent, and effectively reducing the contact area between the first lug and the fixed arm, and the rubber has the anti-skid characteristic, so that the influence of the arrangement of the first bump on the stability between the first bump and the contact arm is reduced.
