Description

Special indwelling needle application for artery

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a needle is kept somewhere in artery special use and is applied ointment or plaster.

Background

Clinically, critical patients or intensive care patients have poor conditions, high operation difficulty and high bleeding, and surgical patients need continuous blood pressure monitoring, and the side pressure of a blood pressure cuff cannot meet the requirement and usually need arterial catheterization for pressure measurement. The most commonly selected radial artery is placed in the radial artery at the heart end near the styloid process of the radius by using an arteriovenous indwelling needle or an arterial indwelling needle, and is connected with an arterial manometry device to continuously observe the change of arterial blood pressure.

The vein which is usually selected to be used as the peripheral venous transfusion and is arranged in the venous indwelling needle is shallow, can be generally seen by naked eyes, has small angle for puncturing the vein by using the venous indwelling needle, is basically parallel to the skin by 0-15 degrees, and is fixed by using the venous indwelling needle after the puncture is successful. However, the artery is deep and invisible to the naked eye, and can only be punctured blindly by the feeling of pulse palpation of the doctor's hand, or punctured by applying more and more ultrasonic direct vision nowadays. The puncture angle of the artery puncture by using the indwelling needle is usually 30-45 degrees with the skin, which is larger than the puncture angle of the vein, and the puncture difficulty and the puncture angle of the patient with a fat arm are larger. Moreover, the most commonly used artery is the radial artery, the puncture position is near the styloid process of the radius, the puncture position is close to the root of the palm, and the puncture is easy to be broken or separated after being placed in a tube. If it is fixed to paste the skin with the vein indwelling needle is applied ointment or plaster and is directly carried out flatly, make the artery indwelling needle keep somewhere the hose of needle and turn over in skin department easily sometimes, influence artery pressure measurement effect, we can fill up a very little gauze at ordinary times, perhaps fill up a cotton swab under the needle file of keeping somewhere the needle, the reuse is kept somewhere the needle and is applied ointment or plaster and fix, such method is loaded down with trivial details and sometimes fixed not good enough, make easily and keep somewhere the needle slippage, it is painful to increase patient puncture once more, increase the injury risk, we propose an artery special use and keep somewhere the needle and apply ointment or plaster to these problems.

SUMMERY OF THE UTILITY MODEL
