Abstract
A marker capsule for a drug delivery dart that marks a animal upon impact to indicate it has had a drug injection. The marker capsule is formed of a rupturable material, and has a central aperture formed therethrough for disposition about a cannula extending from the drug delivery dart. A marking substance is contained within the capsule. The capsule ruptures between the dart body and the animal upon impact to thereby disperse said marking substance upon the animal about the area of the impact.
Claims13
A marker capsule for use in conjunction with a drug delivery dart used to inject a drug into an animal upon impact therewith, the drug delivery dart having a dart body and a cannula extending therefrom with a collar disposed about the cannula that serves to retain the dart in place after it impacts the animal, the marker capsule comprising:
- a capsule formed of a rupturable and flexible material, and having a central aperture formed therethrough, said aperture sized for disposition about the drug delivery dart cannula, and wherein said flexible material stretches to allow the collar on the cannula to pass therethrough and further relaxes to effectively retain said capsule on the cannula between the dart body and the collar;
- a marking substance contained within said capsule, and wherein
- said capsule ruptures between the dart body and the animal upon impact to thereby disperse said marking substance upon the animal about the area of the impact.
A method of marking an animal when impacted by a drug delivery dart that has a dart body and a cannula extending therefrom with a collar disposed about the cannula that serves to retain the dart in place after it impacts the animal, using a marker capsule formed of a rupturable and flexible material, and having a central aperture formed therethrough, the capsule filled with a marking substance, the method comprising the steps of:
- engaging the capsule with the drug delivery dart by inserting the cannula through the aperture in the capsule, thereby stretching the flexible material as the collar passes through the aperture, and wherein the flexible material relaxes, thereby effectively retaining said capsule on the cannula between the dart body and the collar;
- impacting the drug delivery dart against the animal such that the cannula pierces the animal, and thereby
- rupturing the capsule between the dart body and the animal upon impact to disperse the marking substance upon the animal about the area of impact.
A drug delivery dart with a marking feature that is used to inject a drug into an animal upon impact therewith while leaving a visible mark to indicate that a drug dose has been injected, comprising:
- a drug delivery dart having a dart body and a cannula extending therefrom with a collar disposed about said cannula that serves to retain the dart in place after it impacts the animal;
- a capsule formed of a rupturable and flexible material, and having a central aperture formed therethrough, said aperture disposed about the drug delivery dart cannula, and wherein said flexible material stretches to allow the collar on the cannula to pass therethrough and further relax to effectively retain said capsule on the cannula between the dart body and the collar;
- a marking substance contained within said capsule, and wherein
- said capsule ruptures between said dart body and the animal upon impact to thereby disperse said marking substance upon the animal about the area of the impact.
