Definitions

  • the present disclosure relates to applicators, and in particular, but not exclusively, to applicators used to inject medications into animals, such as pigs, for example.
  • Injections of medication are typically carried out using needle containing injectors or applicators.
  • medication is used herein to include any drug, medicine, remedy, therapeutic preparation, vitamins, neutraceuticals, vaccines, antibodies, and the like.
  • applicators are frequently used with animals, especially livestock, because of the large number of animals that need to be injected. Because of the use of needles to administer medications, there is a possibility that the users could accidently stab themselves with the needle, or even inject the medication into themselves.
  • Injections of medications for livestock can require the user to inject hundreds of animal in a single setting. Each injection requires the user to apply force to insert the needle into each animal and deliver the medication. By injecting hundreds of animals, the user may be subject to repetitive motion injuries.
  • a handheld injection safety applicator includes an applicator housing with a handle and a retractable needle housed within the applicator.
  • the applicator further includes a first sensor that detects the presence of a user's grip on the handle and a second sensor that detects the presence of an animal.
  • the applicator also includes processing circuitry configured to receive a first signal from the first sensor indicating that the user is gripping the handle and receive a second signal from the second sensor indicating that an animal is detected. The applicator extends the needle out of the applicator into the animal once the first and second signal are received and delivers a dose of medication into the animal once the needle is fully extended into the animal.
  • the retractable needle only extends when the applicator detects that the user is holding the handle and detects the presence of the animal. Because the needle only extends after both sensors have been triggered, accidental needle sticks are minimized, helping make the applicator safer for the user.
  • the force needed to insert the needle into the animal, and deliver the dose can be provided by a linear actuator within the applicator. Since the insertion of the needle and the delivery of the medication are fully automatic, the process requires little force on the part of the user and the repetitive force and motion of injecting lots of animals is reduced for the user. This may ameliorate problems with repetitive motion injuries and the like.

  • the retractable needle 106 can be replaced after several injections. to maintain the integrity of the retractable needle 106 .
  • the applicator 100 may include a hand guard 110 that is placed in front of the handle 104 , to act as a guard between the handle 104 and the animal being injected.
  • the handle 104 does not include a mechanical trigger for injection, and does not include any manual mechanism for actively activating the injection.
  • the insertion of the needle 106 into the animal, and the delivery of the medication are done automatically, as described next. This can be accomplished through the use of sensors on the applicator 100 . When the sensors detect a particular situation, the applicator 100 inserts the needle 106 into the animal, and delivers the dose, with minimal action from the user.
  • the applicator 100 can have two different sensors. A first sensor that detects the user's presence and a second sensor that detects the presence of the animal.
  • the first sensor can be a handle presence sensor 112 that senses the user gripping the handle 104 . Therefore, when the user grabs the handle 104 of the applicator 100 with their hand, the handle presence sensor 112 is activated.
  • the handle presence sensor 112 can be a capacitive sensor that uses a thin copper sheet placed inside the handle as illustrated in FIG. 1C , or any type of sensor for detecting the user's presence known to one skilled in the art.
  • the handle presence sensor 112 sends a signal to processing circuitry to turn on the applicator 100 and to prepare for injection. When the applicator is turned on, a screen 114 and a light 116 turn on and light up to indicate to the user that applicator 100 is ready for use.

  • the second sensor can be an animal contact sensor 118 , such as a LDC1051 of Texas Instruments.
  • An example of a mechanical animal contact sensor 118 is illustrated in FIG. 1C .
  • the animal contact sensor can include a solid member that is parallel to the retractable needle 106 . When the solid member comes in contact with the animal skin, the solid member retracts from an extended position to a retracted position. When the solid member is in a retracted position, a signal is sent to the processing circuitry that the nose 108 of the applicator 100 is against the skin of the animal.
  • the solid member depresses which indicates that the user is applying the nose 108 of the applicator 100 on the animal.
  • sensors are within the scope of the present description, including noncontact sensors, magnetic sensors, electrical sensors, mechanical sensors, optical sensors and the like.
  • the processing circuitry controlled applicator 100 can control the extension of the needle 106 .
  • the processing circuitry can control the administration of a dose of medication to the animal automatically and without any further action from the user.
  • the needle 106 cannot extend without the processing circuitry receiving a signal from both sensors.
  • a linear actuator within the applicator can apply the force needed to insert the needle 106 into the animal and deliver the dose.
  • the extension of the needle 106 from the applicator 100 and insertion into the animal can be regulated to ensure that the proper depth of the needle 106 is achieved to properly administer the dose. Because the needle 106 is inserted to a proper distance, an exact dose can be administered. In settings where large amounts of animals are injected, sometimes a proper amount of medication is not injected into the animal, leaving an animal undermedicated for its intended purpose. To compensate for undermedicating an animal, some users administer a large dose of medication to ensure that every animal receives enough medication. However, this practice wastes medication by overmedicating most of the animals. By ensuring that the exact dose is administered, the animals do not need to receive larger doses to ensure that all the animals receive the proper amount. This way, medication is conserved.
  • the applicator 100 can also include a medication slot 120 .
  • the medication slot 120 can be located on one of the sides of the applicator 100 .
  • a medication bottle 122 can be inserted into medication slot 120 . Once the medication bottle 122 is inserted in the medication slot 120 , the medication bottle 122 acts as a medication reservoir for storing the medication. After each injection, a predetermined amount of medication is pumped from the medication bottle 122 into the applicator 100 for the next dose.

  • the user can focus the laser on a specific location on an animal to inject the medication. This can help ensure the user inserts the needle 106 in the proper location on the animal.
  • the applicator 100 can have a second slot 126 on the opposite side of the medication slot 120 .
  • the second slot 126 can house marker ink for marking the animal after the animal has been injected with a dose of medication.
  • the second slot 126 can have an orifice 128 through which the ink can be actuated to mark the animal. Improperly marking an animal before it has received a dose can lead to the user believing that animal has received a dose when it actually has not. Or if the animal does not receive enough medication, the animal may not be properly medicated. Therefore, the processing circuitry can control the delivery of the ink, such that the ink only marks the animal after a successful delivery of the medication has been performed.
