Technical Field

The invention relates to the technical field of medical instruments, in particular to a PICC (peripherally inserted central catheter) patient arm bracket vehicle.

Background

Peripherally inserted central venous catheterization, also known as PICC catheterization, utilizes a catheter to puncture a peripheral vein (the most preferred basilic arm vein) and the distal end of the catheter directly reaches the superior vena cava. At present, the PICC catheterization is widely used in clinic and is mainly used for long-term intravenous infusion, infusion of irritant drugs or toxic drugs (chemotherapy), infusion of hypertonic or viscous liquid (such as TPN) and the like. The technology of putting into the pipe also constantly develops, at present, what my institute has generally developed clinically is through improving the technique of inserting PICC pipe of the little puncture instrument of stopper under the supersound guide, and this technique has changed traditional PICC and has put tub position, puts tub position and shifts up the upper arm from below the antecubital fossa, has alleviateed and has put tub damage, has reduced the emergence of pipe correlation problem and complication, has improved patient's quality of life.

Patient is putting the pipe in-process, needs to have special requirement of putting to tub side arm, puts tub patient's arm bracket car as a PICC in patent application CN201820065377.9, relates to auxiliary instrument technical field. PICC puts a tub patient's arm bracket car includes: a vehicle body; the arm bracket structure comprises a guide rail, a guide block, a vertical pipe, a support rod and a first support plate for supporting the arm of a patient, wherein the guide rail is arranged on the vehicle body along the horizontal direction; and the locking assembly comprises a first locking knob and a second locking knob, the first locking knob is arranged on the guide block and can enable the guide block to be fixed or movable relative to the guide rail, and the second locking knob is arranged on the vertical pipe and can enable the supporting rod to be fixed or movable relative to the vertical pipe. PICC puts a tub patient arm bracket car and makes patient's arm can obtain good fixed, the disinfection of being convenient for and put a tub operation, very practicality.

The existing PICC (peripherally inserted central catheter) catheter holder is used, the clamping mode is usually a linear fixed clamp, a patient is required to pass an arm from a clamping hole to clamp, the clamp is more troublesome in the clamping process of the patient with inconvenient action, and the operation of the catheter is oppositely arranged after the clamp has certain influence, so that the catheter holder can generate obstruction, is inconvenient to clean and disinfect and is easy to breed bacteria due to sweat stains in the long-time clamping process.
