Abstract: A drug composition in solid drug matrix formulation comprising clonidine, midazolam, and fentanyl. The amounts of the drug contained in the solid drug matrix are sufficient to induce sedation in preparation for a clinical procedure. When administered in the mouth, the drug ingredients are absorbed by transmucosal passage. This solid drug matrix formulation may be particularly useful in pediatric dentistry practice. Also disclosed is a method of inducing sedation in a patient by administering the solid drug matrix formulation to the patient prior to performing a clinical procedure.

Abstract: A breathing circuit system for delivering gas from a fresh source to a user through a face mask. The system includes a cylindrical housing and a resiliently-biased valve supported substantially centrally within the housing. In the default or “off” position, the resilient bias causes the valve to be seated on a valve seat shutting off axial flow of gas through the valve housing. When the patient or user breathes, negative pressure is applied to one side of the valve effective to sufficiently overcome the resilient bias imposed on the valve to move the valve off the valve seat axially (or otherwise open in another direction) within the housing, thereby allowing flow of gas through both the valve seat and the valve housing, and into the breathing circuit connected thereto. When the patient's breathing pauses and begins to exhale, the valve bias returns the valve to its default or off condition shutting off flow of gas through the valve.

Abstract: A disposable breathing circuit is adapted to be connected between a disposable face mask and a vacuum source for delivering fresh gas to the face mask and for scavenging waste gas exhaled from the face mask. The breathing circuit includes a fresh gas supply limb and an exhalation limb, and a scavenging limb coupled to the exhalation limb. The scavenging limb includes a one-way valve to prevent re-breathing, a flexible flow-through reservoir bag used to store exhaled gas, and an output tube adapted to be coupled between the flow-through reservoir bag and the vacuum source.

Abstract: A cartridge for folding an ophthalmic implant including pliers having two articulated arms which are provided with substantially coaxial channels and each of which is boarded by two longitudinal edges. The channels are open in front of each other and define a partially folded conduit containing the implant when the two arms are brought to each other.
