Radial artery puncture retainer

Abstract

The invention belongs to the technical field of medical devices, and specifically relates to a radial artery puncture retainer, including an arm support plate. The arm support plate is removably connected with an arc support frame. The arc support frame comprises an arc plate and a pair of guiding barrels fixedly connected to the arc plate. The guiding barrels are slidably connected with fixing sliding columns, and the arc plate is rotatably connected with a power fixing worm which allows the fixing sliding columns to slide in the guiding barrels. The fixing sliding columns are equipped with apress plate, and the fixing sliding columns can drive the press plate to rotate on the fixing sliding columns when sliding on the guiding barrels. The arc plate is rotatably connected with an activecontrol worm controlling the press plate to rotate on the fixing sliding column. The arc plate is rotatably connected with a first transmission worm which controls the sliding distance of the fixing sliding columns in the guiding barrels. The arc support frame can be removed from the arm support plate thereby being conveniently to remove after puncture of a patient; and when the fixing sliding columns drive the press plate to fix an arm, the press plate can automatically adjust the angle, and thus arms of different patients can be fixed conveniently.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a radial artery puncture fixator. Background technique [0002] The radial artery is the most commonly used arterial puncture site. The radial artery is located on the inner side of the radial head in the anterior area of ​​the wrist. Although the lumen of the radial artery is small and the pulse is relatively weak, it is very superficial and easy to touch. It is easy to operate, safe, and easy to expose. It is the most commonly used site for blood collection; radial artery puncture is suitable for complicated and major operations, and continuous monitoring of blood pressure changes is required, patients with unstable hemodynamics and during operations Patients who need blood dilution, controlled blood pressure reduction, etc.; when puncturing the patient, the patient's palm is facing upwards, and the wrist is higher than the palm. Since the radial artery has a thinne...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a radial artery puncture fixer, which effectively solves the problem that the fixer can only be used for some patients, and it is troublesome to disassemble the fixer after the patient is punctured, and the medical staff When puncturing a patient, only the patient's arm can be simply fixed, which cannot effectively prevent the patient's wrist from moving, and it is easy to cause puncture failure and increase the pain of the patient.
