Innovative Design and Clinical Application Evaluation of Insulin Needle Changer
Objective:To design and develop a patented product,"an insulin needle changer",and apply it to insulin injection operations.To observe and analyze the incidence and duration of needle injuries caused by medical personnel injecting insulin before and after using the"insulin needle changer".Methods:From January 2021 to May 2021,252 patients were randomly selected from the Endocrinology Department of our hospital who ordered insulin subcutaneous injection and received regular insulin pen injection.A total of 1260 subcutaneous insulin injections were performed as a control group;Randomly selected 259 in-patients with subcutaneous insulin injection treatment ordered by doctors in the same department from June 2021 to October 2021.During 1368 subcutaneous insulin injections,the"insulin needle changer"was used as the experimental group.The control group only used traditional methods.Before insulin injection,remove the outer cap and place the needle cap on the operating table.After completing the injection,use a single hand-held injection pen to search for the opening of the needle cap on the operating table.After aligning the needle tip with the opening of the needle cap,put the needle tip back into the needle cap,and then rotate the outer cap and needle counterclockwise to complete the operation.The experimental group was supplemented with insulin needle changer on the basis of the control group.Results:In the control group,needle injuries caused by insulin injection occurred 13 times;The number of needle stab injuries caused by insulin injection in the experimental group was 0,with a statistically significant difference(P<0.01);The insulin injection time in the experimental group was shorter than that in the control group,with a statistically significant difference(P<0.05);The satisfaction of medical personnel in the experimental group was higher than that in the control group,with a statistically significant difference(P<0.05).Conclusion:The insulin needle changer is convenient to use and easy to operate,which can help reduce the incidence of insulin needle puncture among clinical medical personnel,shorten the needle replacement time,and improve the satisfaction of medical personnel.
