An apparatus for dispensing medication having a canister containing medication to be dispensed to a user. The canister is movable in both a first and a second direction. The apparatus also includes a mouthpiece that provides a point of egress for the medication. The medication is dispensed to the user when the canister is moved in the first direction. Also included in the apparatus is a switch for completing an electrical circuit. The switch is activated when the canister is moved in the first direction closing the electrical circuit. The electrical circuit is opened when the canister moves in the second direction. A counter module is disclosed for performing a count upon the closure of the electrical circuit. The counter module also and displays a dispensation history of the medication in the canister. The apparatus also includes a seal for isolating the counter module from the mouthpiece and the canister.

A method of making a barbed suture by varying the blade geometry and/or the movement of the blade when cutting a suture is disclosed. The method can also be accomplished with a cutting device to create a plurality of barbs on the exterior of surgical suture. The barbs produced using the method with the cutting device can be the same or random configurations.

An apparatus for cutting barbs into a suture having a filament supply. The apparatus also has an in-feed collet for holding one end of a filament threaded therethrough. Further the apparatus has an out-feed collet for holding a second end of a filament threaded therethrough. Additionally, the apparatus has a holder positioned between said in-feed and out-feed collets for holding a filament suspended between the in-feed and out-feed collets. The apparatus also has a cutting assembly for cutting barbs in the filament tensioned between the in-feed and out-feed collets.
摘要:
A method for manufacturing self-retaining suture is disclosed. The method provides for creating and supporting a suture during cutting of tissue-grasping elements at different angular positions. A cutting device is moved through the suture thread along a path which can include longitudinal, transverse, oscillating and depth components to create a desired tissue-grasping element on the surface of the suture. The path of the cutting device and the rotation of the suture relative to the cutting device are controlled so that a plurality of angularly-displaced tissue-grasping elements can be created on the suture.
摘要:
A counter for indicating the number of doses left in a canister that is suitable for use in a metered dose inhaler. The counter is affixed to the canister and includes a module for providing an indication of the number of doses left in the canister and a triggering mechanism for updating the indication in response to activation of the inhaler.
摘要:
A dry powder inhaler having a housing, at least one single dose storage chamber able to contain a single unit dose, a discharge path adjacent the storage chamber, and a flexible and bendable seal plate closing the discharge path. When an air flow under pressure is applied to the top of the dose, the top seal is broken and the dose is driven against the seal plate which deflects away, allowing the powder of the dose to be driven into and along the discharge path. The air flow causes the seal plate (in the discharge path) to vibrate, which acts to break up the dose into particles of preferred size, as the dose is carried along with the air flow and delivered to a patient.

摘要:
A breath actuated metered dose inhaler including a housing, a mouthpiece positioned at one end of the housing, and a mechanical release mechanism positioned at another end of the housing. The release mechanism is triggered by a diaphragm and the inhaler is configured such that the air inhalation pathway is unimpeded by the release mechanism.
