Description

A kind of indwelling pin fixing protective device for pediatrics

technical field

The invention belongs to the technical field of pediatric medical devices, and in particular relates to a protective device for fixing a pediatric indwelling needle.

Background technique

When infusions are performed on children, unlike adults, they do not puncture in areas such as arms and palms, but mostly choose the position of the head and forehead. This is because: 1. Reduce discomfort. We all know that infusions Sometimes the hands feel cold, numb, or even painful. This is because the temperature of the liquid medicine is low during the infusion. For children, the capillaries on the hands and feet are relatively small, even if they are When there is no infusion, the hands and feet will often feel cold; 2. Prevent the child from pulling the needle and running the needle; 3. It is easy to stick the needle. The blood vessels on the hands and feet of children are relatively thin and difficult to find.

Indwelling needles are often used for infusion, especially for children, because the use of indwelling needles can reduce the pain caused by repeated venipuncture and the fear of injections in children, reduce the anxiety of parents, and facilitate clinical medication. The patient's rescue medication reduces the workload of the nurses, but now the indwelling needle is directly fixed on the patient's head by tape, and there are some problems. The secreted sweat and oil easily reduce its adhesion; and in order to make the indwelling needle not easy to fall off, it is necessary to wrap the head with a large area of tape, so that the tape sticks to the hair, and the pulling caused by the replacement will cause pain to the child; and the long infusion tube It is easy to be pulled by children, and for the convenience of operation, the infusion tube and the indwelling needle are mostly connected by direct insertion, and there is a danger of pulling and falling off if there is a slight carelessness. Therefore it is necessary to provide a pediatric indwelling needle fixing protector to solve the above problems.
