    Abstract: A dual mode pistol grip grease gun that operates in either the volume mode or the pressure mode. The grease gun includes a cylinder head having a handle attached thereto. Attached to the cylinder head via a shiftable link is a lever, which has a slot at one end. The shiftable link is disposed in the slot of the lever, and its position therein defines whether the grease gun is in the volume or the pressure mode. The shape of the slot is such that, when the grease gun is in volume mode and when the lever is fully pressed toward the handle, an angle defined by a first axis (defined as a line connecting a pivot point of a connection of the link to the cylinder head and a pivot point of a connection of the link to an end of the slot defining volume mode) and a second axis (defined as a line connecting the pivot point of the connection of the link to the end of the slot defining volume mode and a point along a bottom curve of the slot where the concavity of the curve changes) is approximately ten degrees.

  • Patent number: 8206335
    Abstract: The present invention provides fluid and material delivery methods and devices for practicing the methods. The invention provides a method of delivering cellular material comprising injecting the cellular material into a subject such that the injected cells retain their inherent morphologic characteristics upon injection. The method comprises the steps of aspirating the cellular material into a fluid delivery device which incorporates a syringe arrangement. The cellular material is aspirated into the main body of the syringe until the desired amount of a material has filled the syringe body. The needle of the fluid delivery device is then inserted into the skin of a subject at an angle about parallel to the skin until a desired depth has been reached. The cellular material is then injected in the subject until the desired volume of material has been injected. The needle of the device is then rotated approximately 45 to 90 degrees and the needle is removed from the injection site.

  • Publication number: 20110284123
    Abstract: Metered dose applicators that irradiate a portion of light sensitive product. When a dropper applicator is secured to a reservoir, a usable volume inside the dropper is reduced. As the dropper is removed from the reservoir, the usable volume in the dropper increases, creating a suction within the dropper that draws product into the dropper from the reservoir. When the dropper is off the reservoir, then a button that is accessible to a user is used to increase and decrease the size of the usable volume. The button also turns on a light that is effective to activate the product as it is being dispensed from the dropper.
