1. An apparatus, comprising:
a needleless syringe, comprising
a generally cylindrical tubing having a generally open first end, a second end, and an inner circumference defining a chamber,a first flange located at the first end of the tubing, the first flange adapted to accommodate a human finger,the second end of the tubing narrowing into a neck, the neck having a channel that is fluidly coupled to the chamber; a plunger, comprising
a shaft having a first end and a second end,the first end of the shaft terminating at a piston having an outer circumference flush with the inner circumference of the syringe,the second end of the shaft terminating at a terminus having a pressure-detentable push-button switch thereon, the terminus also having therein a powersource,a sleeve accommodating a first wire and a second wire, the sleeve substantially transversing the length of the shaft from the terminus to the piston; and a circuit, comprising the power source secured in the terminus, a light source proximate to the piston, the first wire electrically couples the light source to the power source through the sleeve, and the second wire extending from the light source through the sleeve and to the pressure-detentable push-button switch, such that the second wire electrically couples the light source to the power source when the pressure-detentable push-button switch is compressed. |
