(Cl. 123253) The present invention relates to a novel package for transcutaneous injection by which inoculation or vaccination may be quickly and easily carried out.
For many years it has been the common practice to vaccinate with various antigens by inoculating with a syringe and an injecting needle intracutaneously, subcutaneously, or intramuscuiarly. For smallpox vaccination the virus has commonly been introduced percutaneously by depositing a film of the liquid vaccine on the skin and puncturing or scratching the skin through the vaccine with an ordinary needle or the like over a relatively small area. In each of these commonly used methods the vaccine is concentrated in a small area and, as a result thereof, these prior methods have often led to either generalized or localized reactions of a severe and undesirable character.
The present inventor some years ago discovered that such undesirable reactions could often be avoided and vaccination could be more quickly and easily accomplished by introducing a vaccine into the skin transcutaneously by multiple punctures of identical character and depth distributed over a substantially greater area of the skin than had been employed in prior vaccination methods, and on December 2, 1952, applicant was granted United States Patent No. 2,619,962 on a vaccination appliance by which vaccinations could easily be made employing this multiple puncture technique. The vaccination appliance disclosed in said patent comprises a thin metal plate having needles punched therefrom and projecting in parallel relationship from one side thereof outwardly beyond the level of the adjacent surfaces of the plate. As disclosed in the patent, vaccination was accomplished by cleaning the surface of the skin with alcohol or the like and a quantity of vaccine, in either liquid or powdered form, was then spread over the area where the vaccination was to be effected. The vaccination appliance was then placed against the surface to which the vaccine had been applied and it was pressed inwardly, thereby forming a plurality of punctures of the skin with a resulting transcutaneous injection of the vaccine at the site of each puncture, with out scarification of the skin.
The vaccination appliance of my prior patent is now being widely used with excellent results, and the present invention is related thereto in certain respects in that the present new package by which vaccination and inoculation to skin testing may be effected more easily and quickly, utilizes a form of the appliance broadly covered by my prior patent.
One of the principal objects of the present invention is to provide a prepared package for etiecting transcutaneous inoculation, which package is complete in itself and is of a nature such that it may be readily stored in large numbers without special precautions and may be supplied to physicians and hospitals in the same manner as ordinary medical supplies. Another object of the invention is to provide a vaccination or inoculation package of the kind just stated which may be quickly and easily used, and is ready for use immediately upon opening of the package. Still another object of the invention is to provide such a package which renders unnecessary the usual use of a needle and syringe for withdrawing vaccines and skin testing materials from ampules and the usual reconstituting of such vaccines and testing materials, and renders unnecessary the use and handling of liquid or powdered vaccines and skin testing materials by the physician or nurse, thereby greatly simplifying vaccination procedures and eliminating or greatly reducing the chances for human error during the making of vaccinations and skin tests.
The new prepared package, in one of its forms, comprises a substantially rigid backing member having secured thereto a thin metal plate having a plurality of needle-like projections punched therefrom, and with a dried antigenic substance on each of the needle-like projections. The backing member, in this form of the package, has removably secured thereto a substantially rigid, imperforate, bubble-like cap that completely covers the metal plate and its needle-like projections so as to protect the projections and prevent contamination of the dried antigenic substance thereon prior to use of the package in inoculation. In order to make a vaccination or skin testing inoculation with the package, the physician merely needs to clean the skin area where the vaccination or inoculation is to be made. He then opens the package by removing the cover, whereupon, by gripping the backing member in his fingers, he presses the needle-like projections of the thin metal plate against the skin, thereby simultaneously puncturing the skin at a plurality of points. He holds the device in this position only for a short time until the lymph or other body fluids in the deeper recesses of the skin dissolve the antigenic substance olf the embedded projections. It is desirable, although not necessarily essential, that the thin metal plate be rotated slightly in a circular motion, but without scarification, while the needle-like projections are embedded in the skin, thereby tending to wipe all of the antigenic substance off of the projections and deposit the same in or under the skin. The vaccination or inoculation, in any event, will then have been completed and the instrument can be withdrawn and discarded. It will immediately be appreciated that the entire vaccination or inoculation procedure will, therefore, require only a few moments when one of the present new packages is employed, and that no clean-up of equipment will be needed or involved.
()ther objects and advantages of the present invention will be apparent from the following description of a preferred form of the package, with variations, and a preiered manner by which it may be used. In the accompanying drawings:
FIG. 1 shows a perspective view of the arm of a patient upon which a vaccination or skin test inoculation is being made with the use of one of my new vaccination or inoculation packages;
FIG. 2 is a side view in elevation of one of my new packages;
FIG. 3 is a top plan view thereof with the bubblelike cover removed;
FIG. 4 is an enlarged cross-sectional view taken substantially along the line 4-4 in FIG. 3, but showing the cover in place;
FIG. 5 is a similar View taken substantially along the line 5-5 in FIG. 3;
FIGS. 6 and 7 are similar to FIG. 5, but they show variations in the way in which the thin metal plate may be secured to the backing member, and they shown a variation in the way in which the cap or cover may be secured in protective position upon the backing member;
FIG. 8 is an enlarged perspective view of one of the thin metal plates prior to mounting upon a backing member;
HG. 9 is a similar view of another form of thin metal plate which may be employed in vaccination packages in acordance with the present invention;
FIG. 10 is a greatly enlarged view of one form of needle-like projection on one of the thin metal plates, showing the projection as being perforated in order to increase the amount of antigenic material that may readily be applied thereto and dried thereon pursuant to the present invention;
FIG. 11 is a view similar to FIG. 10, but showing a needle-like projection pitted or scarilied, as by sandblasting, in order to increase the amount of antigenic material that may readily be applied thereto; and
FIG. 12 is a similar view of another needle-like projection, showing the surface of the projection scarified as by scratching. I As illustrated in the drawings, one package embodying the present invention is comprised of a single piece backing member 11 which has a generally flat or planar central portion 12 with a pair of wing-like projections 13 and 14 extending from opposite sides or ends thereof so that the backing member may easily be held and manipulated by the fingers. The backing member if is preferably formed of a suitable substantially rigid moldable plastic material, such for example as polystyrene, polyethylene, nylon or Teflon. in the form of the package illustrated in FIG. 5 the central area of the central portion 12 of the backing member is somewhat thicker than the Wing-like projections 13 and ii-d so that the upper side of the central portion 12. provides a raised platform 12:: having a peripheral overhang 325, beneath which there is a peripheral slot 12c. This overhang 12b and the slot 120 are adapted to receive an inwardly directed flange or lip 15a of a bubble-like cover 15 which is preferably transparent and which, like the backing member 11, may be formed of a suitable molded plastic material.
In the form of the package shown in FIGS. 3 to 5, the raised platform 12a has a pair of recesses 12d formed therein. The recesses 12d are of gradually increasing depth, as best seen in FIG. 5, and the opposite side walls of each recess are provided with projecting nibs or detents 1212, beneath which there are received tongues 16a that are formed integrally on the opposite ends of a thin metal plate 16. The underside of the metal plate thus lies fiat against the surface of the raised platform 12a, with this surface, in the present case, backing-up or supporting the backside of the plate, and particularly the area adjacent needle-like projections or tines 16b that are formed on the plate as explained below, and the plate is rigidly fixed and retained in this position by the presence of the tongues 16a in the recesses 12d and by the detents 12a which secure the tongues in the recesses.
The plate 16, as best seen in FIG. 8, may be generally of a rectangular configuration with four or more sharply pointed needle-like projections 16b punched from the central portion of the plate, thus leaving a rectangular opening 160 at the center of the plate. The needle-like projections are preferably of uniform length and size and they project at right angles from the plane of the thin metal plate 16 from 1 to about 4 mms, depending upon the type of vaccination to be accomplished.
Each of the needle-like projections 16]; is coated with a dried antigenic substance 17, as will be more fully explained below, and the cover or cap 15 protects the projections 16b and prevents contamination of the dried antigenic substance prior to use of the package in effecting a vaccination or injection.
The forms of the package shown in FTGS. 6 and 7 are similar to the form shown in FIGS. 3 to 5 except as to the way in which the cover is applied to the backing member 11 and the manner in which the metal plate 16 is secured to the backing member. In FIGS. 6 and 7 the top of the central portion 12 of the backing member is flat and without the raised platform 12a shown in FIG. 5, and the cover 15 is not provided with a lip or flange around its periphery. On the contrary, the peripheral edge 15]) of the bubble-like cap or cover 15 in these modifications is plain and is removably received in a tight fit downwardly into an annular slot 12f formed in the upper surface of the central portion 12 of the backing member. The metal plate 16 shown in FIG. 6 differs from that shown in FIGS. 3 to 5 and 8 in that the tongues 16a are apertured and the plate is secured to the central port on 12 of the backing member by means of rivets l5 whlch extend through the apertures of the tongues and through the body of the central portion 12 of the backing member, the rivets preferably having flat heads at their ends ad jacent the metal plate 16. In FIG. 7, on the other hand, the tongues on the metal plate 16 are somewhat longer than those shown in FIGS. 3 to 6 and 8 and provide tabs- 16d which extend to the rear side of the backing meme her through apertures 12g provided in the central portion 12 thereof, where the free ends of the tabs 16a are bent over, as shown in FIG. 7, in order to secure the rnetar plate upon the backing member. In all of the forms of the package described above, it will be noted that the central portion 12 of the backing member, backs-up and supports the backside or underside of the metal plate 16.
The present vaccinating packages are useful in a great variety of transcutaneous injections and inoculations with allergens and antigens and biological substances of different kinds. Vaccines, for example, which may be injected into a patient with the use of the present packages include the vaccines for whooping cough, polio, rabies, yellow fever, smallpox and others including the vaccine of Calmette and Guerin, commonly called BCG, for tuberculosis. Testing materials that may be injected by use of the present packages include (but are not limited to) coccidioidin, blasto-mycin, histoplasmin, lepromin and tuberculin, as well as allergens for foods and pollens. In the injection of certain of these materials it may be desirable to use a package employing a somewhat larger metal plate with additional needle-like projections thereon, and an example of such a plate is shown in FIG. 9 where the plate is provided with thirty-six projections 16:) rather than the four shown in FIG. 8. Various sizes of plates may, of course, be employed with backing members 11 of different sizes, depending upon the vaccination rcquirements.
In preparing the packages, the metal plates 16 are cleaned and the needle-like projections 16b thereof are thereupon coated with the desired wet antigenic or aller-' genic or immunizing or testing substance by merely dip-' ping the projections into a liquid solution of the substance or by cataphoresic or electrophoresic deposition of the substance upon the projections. The amount of the wet substance retained upon the projections may be increased by a scarification of the surfaces of the projections. This may be done in several ways. For example, in FIG. 10 the projections 16!) are shown to have been pierced by a plurality of very small openings The; in FIG. 11 the surfaces of the projections are shown to have been roughened or pitted as by sandblasting; and in FIG. 12 the surfaces have been roughened as by scratches 16 Due to the surface tension of the antigenic or allergenic solution, a greater amount of the wet antigenic or allergenie substance is retained upon the projections 16b than would be the case if the surfaces of the projections were smooth. In any event, the projections 16b are then removed from the solution and the antigenic or similar substance is then dried upon the projections. In the case of most non-viable antigens this drying may be carried out in air at about 37 C. In the case of viable antigens, however, it is preferable to freeze-dry the substance upon the projections. In so doing, the wet substance is first frozen upon the projections by lowering the temperature to as much as minus 45 C., whereupon the metal plates with the frozen material thereon are placed in a vacuum chamber and left there for from 7 to 18 hours while the temperature is permitted to rise gradually to about 20 C.,
The thin metal plates 16, with the dried antigenic substance upon the projections 16b thereof, are then secured in backed-up position upon the backing members 11. In the case of the package illustrated in FIGS. 3 'to 5 this. is done simply by flexing the tongues 16a downwardly intovv the recesses 12d and snapping the tongues past the detents 12c. The detents 12c thereupon retain the plate 16 in place. In the case of the package of FIG. 6 the tongues 16a are riveted in place, as shown, and in the case of the package of FIG. 7, the tabs 16d are pushed through the apertures 12g and are then bent over on the underside of the backing member 11 in order to retain the plate 16 upon the backing member. When the antigenic substance on the projections 16b is of a non-viable type, the assembled plates and backing members and the caps 15 are then appropriately sterilized, such as by steam or ethylene oxide or by any other suitable sterilizing compound. When the antigenic substance is of a viable type, on the other hand, sterilization must be accomplished before the substance is applied to the projections 16b. In the case of the package of FIGS. 3 to 5, the cover 15 is pressed downwardly onto the backing member so that the annular lip or flange 15a snaps over the overhanging shoulder 12b and comes to rest in the annular groove 12c, as best shown in FIG. 5. The cooperation of the shoulder 125 with the flange 15a thereupon retains the cover in place and effectively seals the prepared plate 16 so as to protect the coated projections 16b and prevent contamination of the antigenic substance 17 thereon.
In the case of the packages shown in FIGS. 6 and 7, the cap 15 is applied merely by pressing the cap downwardly so that its peripheral edge 15b seats in the annular groove 12 formed in the upper surface of the backing member 11. The tight fit between the lower edge 15b of the cap and the slot 12 effectively retains the cap in place and maintains the sterile condition of the thinmetal plate 16 and the coated projections 16b thereon.
It will readily be appreciated that the present packages may be easily produced in great number and, when effectively sealed as described above, may be stored for substantial periods at various places about the country and may be supplied, to physicians in normal channels of trade, as is the case with ordinary medical supplies.
When it is desired to effect a vaccination or skin test inoculation with one of the present packages, the package having the appropriate dried antigenic or biological substance on the projections 16b therein is selected. The skin of the patient is sterilized by alcohol or the like and the cap 15 of the package is then removed. In the case of the package illustrated in FIGS. 3 to 5, removal of the cap is facilitated by pressing the center of the cap with the fingers, thus tending to spread or separate the annular edges of the cap and making it easier to remove the cap from the backing member 11. In the case of the packages of FIGS. 6 and 7, the cap 15 in each case is merely forced out of the annular groove 12 This may be facilitated by manually flexing the backing member 11 slightly. Gnce the cap 15 has been removed from the appropriate package, the backing member 11 is held in the hand and the sharp, pointed and coated projections 16!; are pressed into the skin of the patient in the manner illustrated in FIG. 1, the wings 13 and 14 being pressed by the operators thumb and second finger and with the index finger bearing upon the central portion 12 of the backing member 11, so that the projections 16b penetrate the skin and carry the dried antigenic or biological substance thereinto. It will be appreciated that durin this penetration of the projections 16b into the skin, the backing member 11 backs-up or supports and tends to rigidify the thin metal plate 16 so that, despite its thin gauge, there is little or no bending of the plate, with the result that all of the projections 16b may penetrate to a substantially uniform depth predetermined by the length of the projections. This uniformity of depth of penetration is important in many different kinds of injections such, for example, as in performing skin tests wherein each penetration site is in fact a test site, and different depths of penetration may tend to result in different or undesired test reactions at the different sites.
When the projections 16b have penetrated to the desired depth the backing member 11 is then held in this position for a few moments by the operator until the lymph and other body fluids in the deeper recesses of the skin dissolve the dried antigenic or biological substances from the points of the projections 16b. With the backing member held as just described, the backing member is gripped between the thumb and second finger and is preferably given a gentle rotary motion while the projections 16b are still embedded in the skin. This tends to insure that all of the antigenic or biological substance is removed from the projections and deposited in or beneath the skin. The vaccination will then have been completed, and the holder 11, with the metal plate 16 still intact thereon, may then be removed from the patients skin and discarded.
The foregoing description of the present vaccination package with certain variations thereof, and the description of the method by which the packages are prepared and employed in effecting vaccinations or inoculations, have been given for clearness of understanding only and no unnecessary limitations are intended thereby, for it will be apparent to those skilled in the art that various modifications may be made in the packages and in the method of their preparation and use, without departing from the spirit and scope of the claims appended hereto.
