BACKGROUND OF THE INVENTION 
1. Field of the Invention 
Modal application of maneuverable cam lobe action to transferrably effect 
compressive content movement. 
2. Description of the Related Art 
In varied forms, per se cam lobe action has been utilized indefinitely. The 
principal of the peristalic pump, or a common tube of toothpaste, offer 
representative examples, in the singular, of the effect. Applicant is 
uninformed of specific prior implementation for such particular 
application hereinafter disclosed for the multiple-compressive, cam lobe 
conductive ejection of container content involving multiple reservoir 
expulsion, exitable through outlets includable of complementary conductive 
tubing. 
BRIEF SUMMARY OF THE INVENTION 
The novelty of the instant is most clearly and definitively disclosed per 
the following descriptive example of a specific utilization. 
Inherent with standard subdermal tissue, as well as surface skin 
perforation, is accidental scratch/stick (AIDS) exposure. Instant will 
recoup immeasurable expensive healthcare clocktime now wasted by current 
procedures. The object realized in this utilization of the instant is the 
reduction of patient discomfort, as limited to no more than those minimal 
seconds for the implantation of a selected plurality in the standard 
aggregate of injectants. Custom mounted individually by hand, or factory 
standard aggregate-loads, in single plate strips of, say 5 to 10 
appropriately-spaced injectant pod envelopes in conjunctive tandem. 
Implementation is extensible per side-to-side, teamed attachment per 
adhesive side-pads, or transversely securable simply by drugstore adhesive 
tape. An expandable plurality of individual hypodermic ejector pods so 
mountable in-tandem upon an (optionally epidermis-adherable) plate strip, 
and actuatable per contactive compressive transversal thereover by the 
complementary actuator lobes formed in the separate, housing cover shell, 
as slidably interlock-able (to effect simultaneous, en masse, subdermal 
tissue infusion).

DETAILED DESCRIPTION OF THE INVENTION 
The preferred embodiment of the invention includes a first portion 
comprising an appropriately dimensioned, pod mountable, semi-resilient 
plate strip 30 upon which upper surface is fixedly secured a tandem 
plurality of ejector pods 10, each positioned accessibly over identically 
spaced, pre-punched ejection apertures 35. The bottom side of plate strip 
30 is peel-ably adhereable to epidermal surface, in toto, per optional 
contiguous attachment of a free layer of semi-adhesive 32, adherable to 
the said bottom surface of the plate strip. An outer, removable guard film 
39 preserves such adhesive 32. Pods are retained in position per: inherent 
compression of aperture tab 34 with optional, retentive, crimped corner 
tips 36, wedging effect of plate 30 slide-rails, and coincidental 
adherence to that portion of adhesive 32 partially exposed within ejection 
aperture 35. 
The ejector pods 10 are burst-resistant ejectant-reservoirs. They are each 
made of a resilient, axially compressible, hermetically sealed, 
cylindrical pod envelope with a flat upper endwall and a contraposed, self 
penetratable lower endwall. The endwalls are spaced apart per the static 
volume pressure of an injectant loaded there between and sealably joined 
by a resilient thin-film sidewall. Contained centrically suspended 
therewithin is a sterility-assured, hypodermic cannula 13 for subdermal 
tissue implantation, including a strongback or preferred bulkhead and lid 
12 to anchor said cannula 13. For allergy testing, the preferred cannula 
is a which sharply fluted, strengthening, incision-lengthening, linearly 
corrugated cannula 14, having strategic feed flow porting in one end 
thereof, which terminates in an opposite end with an inwardly-tapering, 
beveled, angle-skewed, serrated cutting edge--all, to facilitate 
penetration, while effecting a "shoveling-enlargement" of tissue-access 
incision exposure. A 15% gap in the circumference of its cutting edge 
precludes a tissue "plug" extraction on strip-off removal of spent device. 
In lieu of wasting the excess material per the punched aperture tab 34, the 
same is coincidentally utilized to facilitate smooth, trans-passage of the 
actuator cam lobe 52 over the center of the pod 10. 
Plate strip 30 is complementarily interlocked (30/50) at its lateral 
periphery by compressive latching or interlocking to the shell cover 
housing 50. The actuator cam lobes 52 of the housing 50 are spaced 
complementary of the pod 10 centers. The housing 50 cover shell slidingly 
traverses linearly over pod plate strip 30, its actuator cam lobes 52 of 
housing 50 compressibly effecting simultaneous, collective, expulsive 
dissemination of the total content of all the pods into the epidermis 
and/or deeper. 
Content ejection rate can be slowed, either by deceleration of slide-action 
and/or, per pre-insertion of an open-celled sponge media insert within 
each containment pod. 
Slide-rail contactive friction can be reduced by formed mini-corrugations 
31 on the rail surface and/or, further per an oleic additive into the 
poly-plastic formulation of housing 50. 
Minimal compositional adjustments, including (see FIG. 1B) upsizing for 
interposition of an appropriate, deeper-injecting hypodermic needle in the 
place of the inoculation cannula will transmutably render effective an 
embodiment employable for en masse hypodermic injection as for say, 
military movements (i.e., Persian Gulf), human disasters (i.e., flood, 
earthquake, government aid program), etc. Such a medically standard, 
aggregate-pack, presumably to include such medicaments as tetanus, 
penicillin, vitamin boosters, antidote packs for poisons, etc. Of most 
critical importance is the simplistic functional utilization access by 
those of absolute minimal physical ability--one such human to so "inject" 
another, even the Blind. Professional HealthCare personnel attention is 
thus freed for more complex human-need assistance. 
One mechanical operation of the device is most efficiently disclosed per an 
actual allergy testing embodiment implementation scenario as follows: 
Selected individual inoculator pods 10 are mounted over the fixedly spaced, 
punched apertures 35. The pods are lightly wedged between the peripheral, 
spreadable slide-rails of the plate strip 30, and tucked compressively 
beneath aperture tabs 34 (while coincidentally adhering to the optional 
adhesive layer 32, as partially exposed within ejection aperture 35). 
The peripheral slide-rails of the base plate strip 30 are then 
compressively interlocked with the formed linear shell housing 50. A guard 
film 39 is peel-able to expose an optional semi-mucilaginous layer 32 for 
strip-able contactive adherence of the bottom-side of the device to say, 
the alcohol-sponged vertical quarterpoint of a patients back. 
In one rapid motion, the housing actuator 50 is linearly slid so that the 
actuator cam lobes 52 formed in the housing 50 lid portion are passed 
transversely and compressibly over the aperture tab 34--and thus pod 10 
center--to effect hypodermic dissemination of the specimen into patients 
epidermis. The micro sharp, (optionally silicone and/or Teflon-coated) 
cannula 14 is sharply corrugated for strength and maximum incision 
exposure. The skewed angle of the serrated cutting edge facilitates 
simultaneous penetration (FIG. 1C) through both pod 10 bottom and 
epidermis therebeneath. Minimally-thin pod envelope is formulated to 
centripetally, molecularly contract sealingly around the perimeter of the 
cannula passing therethru. The bevel of the cannula tip tends toward an 
external, circumferential, forced contactive-sealing to resist "blow-by" 
leakage while "shoveling-open" the incision inner perimeter to further 
facilitate infusion thereof. Some fifteen percent of the cutting edge 
circle is absented to preclude any tendency to extract a tissue "plug" 
during strip-off of device. 
Penetrative, collective, total en masse inoculation is effected and device 
is strip-ably removable in less than thirty seconds. Consecutive inoculant 
identification numbers can be (alcohol-soluble) pre-inked onto bottom of 
the optional adhesive layer to be coincidentally and clearly transferred 
adjacent each epidermal inoculation site to facilitate accurate 
observation and recordation. A consummative alcohol sponge bath is applied 
to cleanse overall inoculation site. 
As sized for injection, or inoculation, pod plate 30 with mounted 
contaminated sharps is removable from housing 50, inverted 180 degrees, 
and snap-latchably (30/50/12) re-installed back into housing 50 with 
adhesive 32 (if desired) on bottomside of plate 30 forced hard against 
inside of housing 50 lid. There-fixed, contaminated sharps are 
protectively safeguarded for disposal. Preferred is the in to composition 
of biodegradable poly-plastic--also totally incineratable. 
Intended exclusively to minimize patient discomfort, the total duration of 
mechanical tissue-entry-to-retraction is absolutely assured to consume 
less than some thirty seconds. A textbook example of a decades-old patient 
ordeal of suffering lessened or eliminated per the simplistic efficiency 
of this brand-new fabricated device. Minimization of such sensory testing 
discomfort is most acutely pertinent to the injectee.
