Forearm and wrist adjusting and fixing device for radial artery puncture tube

Abstract

The present invention discloses a forearm and wrist adjusting and fixing device for a radial artery puncture tube. The device comprises a half-finger glove; an arm lower cover plate is hinged to an opening in one side of the half-finger glove; an arm part upper cover plate is hinged to the top of the arm part lower cover plate; the arm part lower cover plate and the arm part upper cover plate jointly form an oval; the bottom of the arm part lower cover plate is provided with an arm fixing plate; the cross section of the arm fixing plate is C-shaped, and the bottom of the arm fixing plate is flat; an arm adjusting device is arranged between the arm fixing plate and the arm part lower cover plate; the arm adjusting device comprises a semicircular threaded sleeve; the bottom of the semicircular threaded sleeve and the arm fixing plate are fixed by welding; the interior of the arm fixing plate is in threaded connection with a steering seat; the exterior of the steering seat is rotationallysleeved with a connecting block; and a friction damp is arranged between the connecting block and the steering seat. The device has the characteristics that an experiment is simple, hemostasis is convenient and forearm and wrist postures are accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a forearm and wrist adjusting fixer for radial artery puncture and catheterization. Background technique [0002] Radial artery puncture is generally used to observe vital signs during surgical anesthesia, and belongs to the project of invasive arterial blood pressure monitoring. [0003] At present, there is no suitable radial artery puncture stent clinically. During the clinical operation or in the intensive care unit, it is found that the position of the patient is not easy to fix when the radial artery is punctured before the operation, and the puncture is difficult. Improper body position causes the catheter for puncture and catheterization to be discounted and unsmooth, which affects the blood pressure measurement results of the radial artery, or even fails to measure the value, which affects the operation process. [0004] Clinically, it is fixed with a fixed lace...

Problems solved by technology

[0003] At present, there is no suitable radial artery puncture stent clinically. During the clinical operation or in the intensive care unit, it is found that the position of the patient is not easy to fix when the radial artery is punctured before the operation, and the puncture is difficult. Improper body position causes the catheter for puncture and catheterization to be discounted and unsmooth, which affects the blood pressure measurement results of the radial artery, or even fails to measure the value, which affects the operation process

[0004] Clinically, it is fixed with a fixed lace or adhesive tape, and even its functional position is fixed by manpower. The effect is very poor, and it takes manpower and material resources and increases the operation time.
