1. A seal-less, hand-held dispensing device for dispensing microliter quantities of a material at a site of a slice wound having a longitudinal length with first and second edges, the edges being spaced apart a distance H where H is in the range from at least about 0.4 mm to about 0.5 mm, the dispensing device comprising:

  • a support platform;

    a first and a second hollow member disposed on the support platform, the hollow members overhanging a predetermined distance beyond the support platform,each hollow member having a predetermined maximum outside dimension that is not greater than about 0.4 mm such that both of the hollow members are insertable into a space defined between the first and second edges of a site of a slice wound without undue disruption of any tissue matter surrounding the site;

    a plunger disposed in each hollow member, each plunger having a predetermined largest outside dimension that is sized for compatible receipt within its associated hollow member,the largest outside dimension of each compatibly sized plunger being in a range from about eighty percent (80%) to about ninety-five percent (95%) of the largest inside diameter of a hollow member in which it is disposed; and

    an actuator having a thumb actuating surface thereon, the actuator being operatively engagable with each plunger and movable with respect to the support platform through an actuating stroke defined between a fully extended position and a fully closed position,movement of the actuator through its actuating stroke displacing each compatibly sized plunger with respect to the hollow member in which it is disposed from a first, loaded, position to a second, dispensed, position.
