Radial artery puncture aid

Abstract

The invention belongs to the field of clinical nursing tools and particularly relates to a radial artery puncture aid, comprising a carrier plate; a rack guide plate extended in vertical direction isarranged on one side of a carrier groove of the carrier plate; the rack guide plate is sleeved with a guide block; a ratchet wheel portion and a pawl portion are arranged in the guide block; a cantilever plate is horizontally extended from the surface of the guide block; a presser plate is arranged at the cantilever end of the cantilever plate; when a patient rests the wrist at the carrier groove,the presser plate is positioned right above the radial artery of the patient's wrist; two groups of through holes penetrate the presser plate sequentially in the length direction of the carrier groove; the two groups of through holes form examination holes respectively which allow an operator to press the index finger and the middle finger inside to detect the pulsation of the radial artery; a needle hole allowing passage of a puncture needle is arranged in an area between the two groups of through holes. The radial artery puncture aid allows puncturing the patient's radial artery to be implemented quickly and efficiently, has the advantages of high operational convenience and one-hand operability and is easy to use clinically.

Description

technical field [0001] The invention belongs to the field of clinical nursing appliances, in particular to a radial artery puncture assistant. Background technique [0002] Blood gas analysis is a reliable method for judging respiratory and circulatory function status and acid-base balance, and is often used as a basis for judging to correct acid-base and electrolyte imbalances. Collecting samples for blood gas analysis through the radial artery has been gradually promoted clinically because it is more convenient and less invasive. During traditional radial artery puncture, a roll of gauze needs to be placed under the patient's wrist, the back is extended, and the skin is disinfected routinely. After that, the operator puts on a hat and mask, stands on the puncture side of the patient, wears sterile gloves, uses the index finger and middle finger of the left hand to detect the pulse at the artery 2 cm above the radial wrist joint and fixes the artery to be punctured. Then,...

AI Technical Summary

Problems solved by technology

Although the above-mentioned radial artery puncture method is becoming more and more mature, there are still the following problems: due to the characteristics of the anatomical location of the radial artery and its surrounding tissues, the operator must keep the index finger and middle finger of the left hand on the radial artery during the puncture operation. At the artery, the puncture is performed while sensing the pulse to avoid puncture errors. On the one hand, both hands of the operator will be occupied, so that there is no time for other operations; on the other hand, during the vertical puncture process of the puncture needle, it may also There is a deflection of the puncture angle caused by hand errors and other factors, resulting in puncture failure, which obviously greatly increases the difficulty of successful puncture and the pain of the patient during puncture
