Abstract

A device to effect simultaneous, en masse compressive-ejection of the content of plural, enveloped-ejectant containment-pods mounted therewithin the device.

Claims

1. A composite device for simultaneous, en-masse cam lobe actuation of the contents of a plurality of individually mounted injectant containment pod envelopes, the device comprising:

a plurality of pods each consisting of a hermetically sealable, self-contained pod unit made of a reconformably resilient, comprehensive envelope having an upper and a lower endwall with an injectant there between, a resilient common film sidewall joining the upper endwall to the lower endwall, and a cannula centrically suspended within the pod unit, the cannula of which comprises an upper butt-end serving as the upper endwall of the pod, a sharpened end opposite the upper butt-end and feed inlet perforations at the upper butt-end; and

a flexible carrier-base plate strip having a plurality of ejection apertures punched there through, each with an individual pod fixed thereto, and an invertible, slidable cover shell housing, complementarily and slidably engaged to the carrier-base plate by means of lateral, snap-in tongue and groove interlocks, having a plurality of intervally spaced actuator cam lobes extending perpendicularly down therefrom to compressibly pass over and thus actuate simultaneous injectant content voiding of the pods mounted correspondingly to the cam lobes upon sliding the cover shell relative to the base plate, whereby upon depression of the upper end walls of the pods toward the lower endwalls, the cannulas of each pod centrically penetrate the lower endwalls for total conductive evacuation of the pod contents, employable as an epidermal inoculator or for deeper subdermal tissue implantation as per appropriate proportioning and cannula selection.

2. The device of claim 1 as applicable to skin allergy testing, further comprising an appropriately formed inoculative cannula, reinforceable per longitudinal corrugation circumferentially about its shaft, and having uppermost strategic feed porting, and a lowermost free end skewed cutting edge, peripherally beveled inwardly, and serrated to facilitate simultaneous, ejective penetration thru discharge endwall to saturate that skin.

3. The device of claim 1, further comprising a means for contactive securement to a planar surface, object, or body part epidermis, having a free layer of a semi-adhesive attachable to the bottom side surface of said plate strip and preservable there per a peel-able guard film thereover.
