Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an indwelling needle fixer for pediatric nursing. Background Art

[0002] The use of intravenous catheters can reduce the pain and fear of injections caused by repeated intravenous punctures in children, reduce parents' anxiety, facilitate clinical medication, emergency and critically ill patients' rescue medication, reduce nurses' workload, and reduce children's pain. Therefore, intravenous catheters are widely used in clinical practice.

[0003] For example, application number: CN202220824127.5 relates to a pediatric nursing indwelling needle holder, including a semicircular plate, the upper surface of the semicircular plate is provided with an indwelling needle fixing and heating mechanism, the fixing and heating mechanism includes a fixing box fixedly installed on the upper surface of the semicircular plate, the lower surface of the inner cavity of the fixing box is fixedly installed with two No. 1 fixing blocks, an insulating plate fixedly connected to the lower surface of the inner cavity of the fixing box is fixedly installed between the two No. 1 fixing blocks, a heating wire is fixedly installed on the upper surface of the insulating plate, and a heat conducting plate is fixedly installed on the upper surface of the heating wire. The pediatric nursing indwelling needle holder, by fixing the insulating plate, the heating wire, and the heat conducting plate in the inner cavity of the fixing box, can heat the liquid medicine in the indwelling needle during use, which can prevent the liquid medicine from being too cold in low temperature weather and causing discomfort to the patient.
