Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pediatric medical instruments, in particular to a hand splint for assisting pediatric nurses in giving injections. Background Art
[0002] Pediatrics is a comprehensive medical science that studies the physical and mental development, health care, and disease prevention and treatment of children. All health and hygiene issues related to children and adolescents fall within the scope of pediatrics. The subjects of treatment are in the growth and development period. Children are mainly divided into respiratory, digestive, circulatory, nervous, blood, kidney, endocrine, genetic metabolism, immunity and neonatal medicine systems to treat sick children.
[0003] Due to the low immunity of children, they are prone to fever and other symptoms when the weather changes. When children have fever and other symptoms, they need to be rushed to the pediatric department of the hospital for injections to ensure their health. However, when medical staff give injections to sick people, the needle will be inserted into the skin, which will cause the body to react with pain. Adults can control their bodies according to their own will to avoid affecting the nurse's injection process by moving their arms, but because children have low control, medical staff will insert the needle into the flesh. When children feel pain, they will cry and react in a stressful manner, and their hands will Unconscious shaking makes it inconvenient for medical staff to give injections to children, which affects the recovery of children. Therefore, when giving injections to children, most of the time, the children's arms need to be restrained and fixed to prevent the children's arms from moving around, so that medical staff can give injections to children smoothly. However, since injections are generally given by drips, the injection time is too long. If the child's arm is kept in a fixed position for a long time, the child's hand will become stiff and numb, making the child feel uncomfortable. Therefore, a hand splint to assist pediatric nurses in giving injections is proposed to solve the above problems. Utility Model Content
