Fixing device special for radial artery puncture

Abstract

The invention provides a special fixing device for radial artery puncture, which includes a base, and a lifting mechanism is fixedly installed on the upper part of the base. There are two lifting mechanisms, which are axially symmetrical about the center of the base. The lifting mechanism includes a cross bar, The middle part of the cross bar is fixedly sleeved with the bushing, the front side of the bushing is fixedly connected to the support arm, the lower part of the support arm is fixedly connected to the pressure plate, and the upper part of the support arm is fixedly connected to the sheath tube clamp, and the sheath tube clamp is fastened by bolts to hold the sheath tube. A puncture needle is arranged in the sheath tube, and the left side of the crossbar is fixedly connected with a rivet. The structure of the present invention sets the sheath tube clamp and the support arm at a fixed angle of 45°, which increases the success rate of the puncture needle for puncturing the radial artery. On the other hand, the stimulation of the needle to the patient is reduced, and the crossbar is fixed at a certain height by fastening the nut, which is convenient for fixing the sheath after the puncture is successful, and reduces manpower to fix the sheath.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a special fixing device for radial artery puncture. Background technique [0002] Coronary angiography is an effective method for the diagnosis of coronary heart disease. At present, during coronary angiography examination, after the radial artery puncture is directly inserted into the arterial sheath, the angiography guide wire is used for observation. [0003] During arterial puncture, the patient's wrist needs to be kept in a supine state. The existing fixation method uses a square support pad under the patient's arm, and binds the patient's arm with a strap to help fix it. Although it can achieve a certain degree of fixation effect, but the patient's arm can still move, which is likely to cause unsuccessful arterial puncture and increase the pain of the patient. After the needle punctures the blood vessel, the medical staff needs to press the sheath for a long time...

[0003] During arterial puncture, the patient's wrist needs to be kept in a supine state. The existing fixation method uses a square support pad under the patient's arm, and binds the patient's arm with a strap to help fix it. Although it can achieve a certain degree of fixation effect, but the patient's arm can still move, which is likely to cause unsuccessful arterial puncture and increase the patient's pain. After the needle punctures the blood vessel, the medical staff needs to press the sheath for a long time, which consumes a lot of manpower
