A syringe finger ring and finger ring inserts, that in various embodiments, provides or connects to a syringe that comprises a syringe body capable of having a volume of material therein and a plunger disposed to enter the syringe body and dispense material from the syringe body by movement of plunger, and a novel a finger ring related structures having an open area and connected, by various structures, to the plunger adapted to receive a finger within the finger ring open area, including a spacer of various embodiments inserted within the open area to selectively reduce the open area and provide more controllable engagement of the syringe plunger by the operator finger in distal and proximal strokes.

The invention features a pharmaceutical suspension containing drug particles, a drug delivery device anchored in the mouth for continuously administering the pharmaceutical suspension, and methods of their use.

The invention features a drug delivery device held in the mouth and continuously administering either a fluid comprising drug dissolved and/or dispersed in water or in a non-toxic liquid, or a drug in solid form.

The present invention provides a method of treating a condition affecting a tooth or periodontium in a subject, comprising administering to the subject's tooth or periodontium a composition comprising biocompatible magnetic, magnetizable, or magnetically responsive agents; and applying an external magnetic field, wherein the magnetic, magnetizable, or magnetically responsive agents migrate to a desired location in response to the externally applied magnetic field, thereby treating a condition affecting the tooth or periodontium in the subject.

An illustrated view of an exemplary improved respirator mask for removing exhaled air from the respirator mask is presented. The respirator mask is useful for providing for the exhaling of air during respiration therapy to be released from the respiration mask to avoid a backflow of the exhaled air. The exhaled air has carbon monoxide, moisture and heat, thus the respirator mask allows for the removal of the carbon monoxide, moisture and heat preventing complications and improving the functionality of the respiration therapy.

Described herein are improved mouthpieces for the delivery of air (sometimes including medicine) to a user. The mouthpieces can include features that enable the user to better keep the mouthpiece in his or her mouth, such as one or more ridges and/or a wider mouth portion; can include features for increased durability, such as one or more internal support pillars; and can include combinations of these features.
