Description

A PICC intubation patient arm bracket cart

technical field

The invention relates to the technical field of medical devices, and more particularly, to a PICC intubation patient arm bracket cart.

Background technique

Peripherally inserted central venous catheterization, also known as PICC catheterization, uses a catheter to puncture from a peripheral vein (preferably the precious vein of the arm), and the end of the catheter reaches the superior vena cava. At present, PICC catheterization is widely used in clinical practice, mainly for long-term intravenous infusion, infusion of irritant or toxic drugs (chemotherapy), and infusion of hypertonic or viscous fluids (such as TPN). The technology of catheter placement is also developing continuously. At present, the technology of PICC catheter placement through the modified Seldinger puncture tool under the guidance of ultrasound has been generally carried out in our hospital. This technology has changed the traditional PICC placement site. The cubital fossa is moved up to the upper arm, which reduces the injury of the catheter, reduces the occurrence of catheter-related problems and complications, and improves the quality of life of the patient.

During the process of intubation, the patient needs to have special placement requirements for the arm on the side of the intubation, such as a PICC intubation patient arm carriage in the patent application CN201820065377.9, which relates to the technical field of auxiliary devices. PICC intubation patient arm bracket cart, including: car body; arm bracket structure, the arm bracket structure includes guide rails, guide blocks, risers, support rods and a first support plate for supporting the patient's arm, the guide rails are along the horizontal The direction is set on the vehicle body, the guide block is slidably set on the guide rail, one end of the riser is connected with the guide block, the support rod is set in the riser and can move in the axial and/or radial direction compared with the riser, the first support The plate is arranged at one end of the bracket away from the guide block; and the locking assembly includes a first locking knob and a second locking knob, the first locking knob is arranged on the guide block and can make the guide block compare to the guide block. The guide rail is fixed or movable, and the second locking knob is arranged on the riser and can make the support rod fixed or movable compared with the riser. The PICC cannulation patient arm bracket cart enables the patient's arm to be well fixed, facilitates disinfection and cannulation operations, and is very practical.

During the use of the existing PICC tube placement bracket, the clamping method is often linear fixed clamping, which requires the patient to pass the arm through the clamping hole for clamping, which is troublesome for patients with inconvenience in the clamping process. Moreover, after clamping, it will have a certain influence on the operation of tube placement, which will cause obstacles, and it is inconvenient to clean and sterilize, and it is easy to breed bacteria due to sweat during the long-term clamping process.

Therefore, in view of this, the existing structure and defects are studied and improved, and a PICC cannulation patient arm carriage is provided, in order to achieve a more practical purpose.
