Definitions

  • the present invention relates to an improved clip for supplying hygienic ballistic implant projectiles to a gun for implanting the projectiles into animals. More particularly, the present invention relates to an improved clip having a rib or blocked chamber stop mechanism for automatically stopping the operation of the gun when the clip is empty.
  • the traditional method for inoculating animals is to use a needle and syringe. This process is time-consuming and labor-intensive, because the animals must be herded and sometimes separated or restrained. Also, the needle and syringe method is stressful for both the user and the animal. Further, the protection level achieved by the needle and syringe method is sometimes very low. Often, the user inadvertently pushes the syringe's plunger before the needle is completely within the animal or as it is being withdrawn from the animal. As a result, there are potential problems of cross-contamination and inaccurate dosage. In addition, there is a danger of contamination when a first contaminated animal is administered with the inoculating device, and ⁇ the same device is then used on successive animals.
  • a convenient, inexpensive and safe way to administer biologicals and pharmaceuticals to animals is to utilize projectiles, each projectile containing a separate dose of a biologically active material for inoculation.
  • Each projectile is fired from a gun at some distance from the animal.
  • the projectile or biodegradable "bullet" is implanted into the animal's muscle, where it dissolves and is carried through the animal's system during the next hours.
  • the biodegradable projectiles are advantageous for several reasons. Each one contains the necessary, accurate dosage depending upon the animal and the inoculation project. Each projectile or bullet can be filled with mixtures of multiple vaccines, bacterins or pharmaceutical products. This eliminates the need for mixing and measuring the product in the field.
  • the bullets can also be stored for an indefinite period of time, especially if they are refrigerated. They are convenient to use, store, handle and ship.
  • the biologically active material within the projectiles is a freeze-dried product. In this form, contamination and loss of potency are prevented.
  • Such projectiles are described in patents assigned to the assignee of this application and are identified as Drake and Paul, U.S. Patent No.
  • a clip containing a plurality of cavities or chambers may be used, each chamber containing one projectile.
  • This type of clip features a rupturable seal on each open end of each chamber, to protect the contents from impurities, providing a hygienically packaged projectile.
  • Another feature of this type of clip is an indexing means which automatically advances the clip so that successive chambers, each containing a projectile, are automatically aligned with the bore of the gun. Each time the gun is fired and cocked, the clip automatically advances and chambers a new projectile.
  • this type of clip contains ten chambers which hold ten projectiles.
  • This clip is described in a patent application assigned to the assignee of this application, and is identified as Fischer and Gould, U.S. Patent No. 4,004,565, issued January 25, 1977.
  • the indexing mechanism associated with the gun is described in patent application identified as Fischer, U.S. Patent No. 4,004,566, issued January 25, 1977.
  • the present invention solves this problem associated with currently available clips, as well as many problems associated with the traditional needle and syringe method.
  • the present invention relates to an improved clip and method for supplying hygienic projectiles to a ballistic implant gun.
  • the clip includes a plurality of cylindrical chambers each of which contains a projectile or biological bullet.
  • the clip also includes indexing means which automatically advances the clip transversely of the gun's housing to supply a projectile to the gun after the preceding projectile has been discharged.
  • the clip further includes a stop mechanism which notifies the user when all of the bullets have been discharged.
  • Two embodiments of the stop mechanism are disclosed. In the first embodiment, the stop mechanism comprises a transverse rib located at one end of the clip. The second embodiment of the stop mechanism comprises a blocked chamber located at one end of the clip.
  • the blocked chamber contains a plurality of integral tabs within the chamber which serve as a stop.
  • the present invention is particularly advantageous in that it provides an effective stop mechanism to prevent firing of the gun when there are no more biologically active projectiles remaining in the clip.
  • the clip advances so that the stop mechanism is aligned with the gun's firing chamber.
  • the trigger is pulled, the bolt hits the stop and the gun is simply unable to operate. This effectively notifies the user when another clip must be loaded into the gun, so that no animals escape inoculation.
  • a still further advantage of the stop mechanism of the present invention is that it has substantial structural integrity. There is little or no possibility that the bolt can extend into the blocked chamber or move against the rib. If for some reason this did occur, the user would be immediately aware of it and would realize that a new projectile clip should be loaded into the gun.
  • a further advantage of the clip of the present invention is that it is adaptable for use with the projectiles or bullets discussed above.
  • the clip is refrigeratable to maintain the biologically active material in a stable form until the inoculation occurs.
  • Each implant projectile is individually sealed in the clip and is not touched after it is has been packaged. The projectiles are thus protected from contaminants such as dirt and bacteria.
  • Still another advantage of the present invention is that the clip allows the user to fire the desired number of bullets, remove the clip, and then store the clip and the remaining bullets until such time when the remaining bullets are necessary. The removal of the clip is permitted without disturbing the hygienic packaging on the remaining implant projectiles. When all the projectiles have been discharged, the clip is disposable, and it is therefore convenient for the user.

  • the gun is adapted to receive the clip of the present invention.
  • the gun 10 permits implantation of a ballistic projectile 22 with sufficient velocity so as to penetrate the epidermal covering of a living animal body and to lodge totally within the body.
  • Both embodiments of the clip of the present invention are designated generally at 15.
  • the corresponding elements of the two embodiments have the same reference numerals.
  • the clip 15 of the present invention is preferably made from an injection plastic molding process. Referring to Figures 2 and 7, the clip 15 includes a web 16 which is generally rectangular in shape having at one end a tapered edge 17 to facilitate insertion of the clip into a transverse guide passage 18 in the housing of the gun 10.
  • the first embodiment of the present invention has fifteen chambers, each containing a projectile, while the second embodiment, shown in Figure 7, has ten projectile chambers 20.
  • the first embodiment of the clip 15 has fifteen "working" chambers 20 and one blocked chamber 33 which acts as a stop mechanism, as explained below.
  • Each of the chambers 20 has opposite open ends and is formed with a connected wall structure to make the clip 15 more rigid.
  • the chambers 20 are positioned in a row along the web. One end of each chamber 20 is closer to one edge of the web 16 than the opposite end for purposes of registration with the guide passage 18 in the housing of the gun 10. Also, one end of the row of chambers 20 is spaced from the tapered edge 17 to provide a tongue on the clip 15.
  • a ballistic implant projectile or bullet 22 Within each of the chambers 20 is a ballistic implant projectile or bullet 22.
  • the projectile 22 comprises a conical nose and annular walls defining a generally cylindrical body which may have a cavity containing the biologically active material.
  • the projectile 22 can be made of any material which is capable of being projected with sufficient force to penetrate a living animal body and which will not shatter upon impacting and entering the body.
  • any of the numerous biomedically approved plastics can be used with advantage and can be selected from among those which are either soluble or insoluble in the animal body.
  • useful insoluble materials are the synthetic organic polymers such as the polyolefins, e.g., polyethylene and polypropylene; polysioxane; polyamides, such as nylon; fluorinated hydrocarbon resins; ABS polymers
  • acrylonitrile butadiene-styrene polymers and the like.
  • a suitable class of polymers which are soluble in animal bodies, e.g., cattle, are the cellulose derivatives such as hydroxypropyl cellulose, available commercially from the Hercules Powder Co. under the trademark "KLUCEL".
  • KLUCEL Hercules Powder Co.
  • the use of soluble projectiles is particularly advantageous, since after implantation, the projectile will be solubilized in and eliminated from the animal's body, eliminating the need to retrieve the projectile 22.
  • the projectile 22 can be a twenty or twenty-five caliber projectile, and the projectile 22 can be loaded with the desired dose of biologically active material.
  • the biologically active material may include antigens, tranquilizers, vitamins, narcotics, etc.
  • Bacterial cells or extracts may be added to the antigen preparation as adjuvants to provoke an increased immune response. Narcotics may be administered to narcotize the animal.-
  • the recesses 27 are indexing means.
  • the recesses 27 are positioned in corresponding spaced relation to the chambers 20 for positioning a chamber 20 in alignment with the bore of the gun 10. There is one more recess 11 than there are chambers 20 to index the clip 15 initially in the gun 10.
  • Each of the recesses 27 includes a wall which forms a rectangularly shaped portion 12.
  • the leading edge wall of each rectangular recess 27 is provided with a radius portion 29.
  • the clip 15 is sequentially advanced transversely of the housing of the gun 10.
  • the rectangular portion 12 of the clip 15 receives a spring-biased clip retainer or detent to hold the clip 15 in place.
  • the radius portion 29 of the clip 15 receives a pawl which advances the clip sequentially from one chamber 20 to the next.
  • Each of the chambers 20 is sealed by a mechanically rupturable seal 25 at each end to protect and aseptically package the projectile from contaminants such as dirt, bacteria, etc.
  • a sealing film 25 is placed along the open ends of the chambers 20.
  • the sealing film 25 is bonded to the clip 15 at each of the open ends of the chambers to individually seal each chamber 20 at each end.
  • the sealing film 25 is preferably a laminate of 0.5 mil (0.0127 mm) polyester and 1.5 mil (0.0381 mm) polyethylene.
  • the sealing film 25 is preferably heat sealed to the molded clip structure 15 to form an impermeable bond around each chamber opening.
  • the clip 15 is preferably formed of a translucent high density polyethylene, permitting the heat sealing of the film thereto.
  • the seal 25 should include an impermeable material such as heat sealable aluminum foil, and the clip 15 should be made of a plastic impermeable to gas and moisture, e.g., a polyformaldehyde resin.
  • the clip 15 alternatively could be formed of injection moldable polyolefins or polyamides, and other sealing films may be used.
  • the motion of the reciprocation of the breechblock causes the bolt (not shown) to withdraw from the clip 15; the hammer to cock; an index arm or lever to reciprocate a pawl and index the clip 15; and the bolt to force the next bullet through the seal 25 and into the firing chamber of the gun 10.
  • the ballistic projectile or bullet 22 is then ready to be "shot” or launched upon pulling the trigger.
  • FIGS 5, 6, 9 and 10 illustrate a clip 15 where the sealing film 25 is ruptured on one chamber 32 at the lead end, and the projectile 22 has been spent or fired from the gun 10.
  • the clip 15 can then be removed from the gun 10 until another implant is desired, and the remaining chambers 20 will remain aseptically sealed. In the alternative, the clip 15 can remain in the gun and the user can continue to fire additional bullets 22.
  • This process of pumping the gun 10 to transversely advance the clip 15 and pulling the trigger continues until all of the projectiles 22 in the corresponding chambers 20 have been released.
  • the first embodiment there are ten projectiles and corresponding chambers, whereas the second embodiment of the clip has fifteen projectiles 22 and fifteen corresponding chambers 20.
  • a radius located next to the final "working" chamber 20 acts to advance or index the clip 15 so that the stop mechanism is aligned with the firing chamber of the gun.
  • the stop mechanism is a rib 14, and in the second embodiment, the stop mechanism is a blocked chamber 33.
  • the bolt of the gun when empty of projectiles, then hits or engages with the rib 14 or blocked chamber 33 rather than a regular "working" chamber 20.
  • the stop mechanism 14, 33 prevents engagement of the bolt with a chamber and further operation of the gun. The operator becomes immediately aware of the fact that the • clip 15 no longer has any bullets or projectiles 22, so that he can load another full projectile clip 15 into the gun 10.
  • the stop mechanism or rib 14 is preferably integrally molded with the remainder of the clip structure 15.
  • the rib 14 extends transversely of the clip itself and parallel to the chambers 20. This transverse configuration of the rib 14 provides additional structural support to assure its effectiveness as a stop mechanism.
  • the stop mechanism or blocked chamber 33 contains a plurality of tabs 30 which preferably extend longitudinally through the length of the blocked chamber 33.
  • the tabs 30 in the blocked chamber 33 are preferably integrally formed with the plastic clip structure 15. While the preferred form of the firearm for. launching or "shooting" the projectile 22 into the ' animal uses compressed gas, preferably air, it is understood that the gun 10 may use other launching devices such as an expanded gas similar to explosive charges.
  • the molded structure 15 is preferably translucent to permit inspection of the projectiles 22, which are formed of a material having a distinct color, preferably not including reds, to color code various biologically active materials. This coating avoids possible confusion when implanting different materials at substantially the same period of time.
