Description

Children's arteriopuncture limb fixation auxiliary device

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a child arteriopuncture limb fixing auxiliary device.

Background

The arterial puncture blood sampling examination blood gas analysis is a vital sign which must be monitored for severe shock patients, various critical patients, complicated major operations, possible major hemorrhage in the operation, extracorporeal circulation intracardiac direct-view operation and the like. Taking radial artery puncture as an example, the wrist is padded with gauze roll, so that the forearm is in a straight position, and the palm part of the patient is fixed by using an adhesive tape or a cloth strip. Conventionally, skin disinfection and hole-paving are carried out by taking the strongest point of radial artery pulsation as a center, an operator wears a hat mask, stands on the puncture side of a patient, wears sterile gloves, touches an artery to be punctured at the 2cm arterial pulsation obvious position on the radial wrist joint by using a left hand index finger and a middle finger, holds an arterial blood and gas blood taking needle, and punctures the artery at an angle of 40 degrees with the trend of the artery. If the bright red blood is seen, the blood is vertically lifted into the injector to indicate that the blood has penetrated into the artery, the left hand is used for fixing the direction and the depth of the original puncture needle, and the right hand is used for injecting liquid medicine or sampling blood at the maximum speed. After the operation is finished, the needle head is quickly pulled out, and the local pressurization is not less than 5 minutes.

The adult artery puncture operation is generally performed by padding an article under the wrist and winding the article with a bandage to perform good fixation, wherein the hand is inclined downwards by taking the article as a fulcrum.
