Produced by Gruppen Tanhauss, the SPRAY Delivery System is a go-to for curing small injuries.
Developed shortly after the production of a self-disposing rejuvenating nanite colony intended for battlefield injuries, the brainstorming of a quick and convenient application device was on the table soon. Driven by UDD demand for a battlefield solution, the concept was put to open tender and various pharmaceutical companies made bids. Tanhauss won the bidding process and got to work.
Initial designs revolved around applying the nanite colony in a gel, applied and rubbed directly into skin. Tests and trials showed that gel had good healing potential, but carried the unintended effect of applying itself to the doctor if they were not wearing gloves. So, designs moved to contain the gel in a 'squirt gun' to prevent this from happening, but the shape of the can and apparatus they were revolving around became too awkward to remain convenient.
When it became clear that the viscosity of the gel was a factor in the design which was proving cumbersome, a finer spray was settled on, reducing effectiveness on serious wounds, but still able to buy a soldier time. After the spray was trialled with the UDD and sold successfully at profit, further iterations of the SPRAY delivery system miniaturised the application device, and upscaled the effectiveness of the spray.
It is important to note that SPRAY is not patented, as per terms dictated in the UDD's bidding process to ensure fair competition, and the creation of generics for the civilian market later. Products similar to SPRAY have been made by other pharmaceutical companies through the Aleph Cluster under a variety of different names.
The SPRAY can is a six inch tall cylinder, two inches in diameter with a handle on the top. The top nozzle is a hermetically sealed, twist-activated top. Once opened, the product inside is good to use for up to 28 days, containing enough spray to coat a 1 by 1 foot area of skin on the patient.
SPRAY itself appears to be a green mist which seeps into flesh, and is luminous under the skin. After a few seconds, the applied spray turns blue as it activates on the patient's skin and starts getting to work over the course of one minute. Once used, the now-grey nanites return to the surface layer of skin to be wiped away.
SPRAY contains a mix of blood coagulants, antiseptics, and chemicals to encourage platelet production in addition to the 'nanites'. This mixture is capable of healing cuts, scrapes, burns, or abrasions on the patient. SPRAY's secondary purpose is to stop bleeding in larger wounds, buying the patient time for a more involved surgery or treatment.
SPRAY cannot reattach severed body parts, though it can 'glue' them in place until help arrives!
Amongst non-Maidenhand humans, SPRAY becomes less effective with repeated applications in a period of two weeks, as the host body identifies and rejects the nanites. At saturation point, the spray will not work as intended, potentially damaging the patient with scars.
