DEVELOPING A PAINLESS INJECTION DEVICE

by WARD, JARVIS

Abstract (Summary)
Receiving shots can cause children severe distress. This paper covers several stages in the development of a painless injection device intended for vaccinations. It will be assumed for the purposes of this paper that physical pain can be eliminated. After searching the literature, observing standard vaccinations and interviewing health care providers, several design criteria for streamlining the vaccination process were identified. A device will be suggested that is: pre-filled, self-adhesive, automated, delivering two vaccines simultaneously and would be safer and faster than syringes. To address the psychological aspects of fear, anxiety and misconceptions concerning the integrity of the body, two diverging aesthetic solutions to the device were tested on children age 1 - 11 years. Their reactions to the models were compared to determine which would better suit the needs of the design criteria. Another test was performed to refine usage issues after problems were identified with the one year olds. It was observed that as children got older they found it easier to refrain from touching the device, a necessary procedural component to success. It was determined that a simple monochrome device is preferable to a more toy like one, because it was less likely to attract attention to the device. Although well tolerated by children older than two, with only moderate parental interventions to prevent attempts to touch or play with the device, it is recommended that for the younger child it be required that the parent hold their child in the lap while sitting at a table where the child's attention and hands can be kept busy with some favored distraction. It is further recommended that a second variation be developed to fit the outer thigh injection site in such a way that the functioning of the device will not be hindered by contact if said child becomes unruly and insists on moving down from the lap or playing with the device.
