Automated Syringe Loading Device
The device will accept insulin bottles of any size or shape and will be able to work with standard 50 unit (1/2 cc increments) or 100 unit (1 cc increments) disposable syringes. The dosage of insulin dispensed by the equipment must be accurate to within .1 unit of the user requested amount. Time-stamped records will need to be kept for any doses that are drawn, and patients will be alerted to how much insulin remains in a bottle following the loading of a syringe. A digital display will present prompts, dosage amounts, and other information in a manner and size that will make it easier for a somewhat visually impaired patient to read. All prompts, amounts, and information will be outputted audibly as well as visually. The interface for the device will have Braille labeling on all of its keys to make the device more usable by partially or completely blind patients. Key size, location, and type will be chosen to make the equipment more usable by individuals with reduced hand motor skills or touch sensitivity. Safeguards will be put in place to prevent the device from attempting to load a syringe when it is not below and vertical to the insulin bottle; (this is to prevent air from getting into the syringe inadvertently). If the user specifies a dosage amount that exceeds the amount of insulin in the bottle or if it exceeds the size of the syringe, the user will be alerted of the error and the syringe load will be cancelled. The finished device will be portable; allowing patients to be able auto-load syringes without needing to be directly plugged into an electrical outlet or a computer.
