About this source
USPTO classification A61M covers devices that introduce or withdraw fluids from the body: infusion pumps, catheters, syringes, inhalers, wound drainage, dialysis equipment, and fluid-handling microfluidics. Every newly published application in A61M lands in this feed, around 205 a month. Applications publish 18 months after filing. Watch this if you compete in infusion therapy or drug delivery, file freedom-to-operate analyses for medical device startups, scout acquisition targets in cardiovascular or respiratory devices, or track hospital R&D arms that are quietly patenting clinical innovations.
What changed
Merxin Limited filed a new patent application with the USPTO for a medicament dispenser featuring a power spring mechanism that tensions and peels lid elongate sheets from blister sheets upon each actuation of the dispensing mechanism. The dispenser is designed to hold elongate form medicament carriers enclosing multiple distinct medicament dose portions.
Manufacturers of inhaler or blister-pack medicament delivery devices should monitor this application as prior art. Pharmaceutical companies developing similar power spring or peel-seal blister dispensing technologies may need to conduct freedom-to-operate analyses to assess potential overlap with Merxin's claimed mechanism.

The elongate form medicament carrier has proximal and distal ends, and blister and lid elongate sheets enclosing multiple distinct medicament dose portions therebetween. The medicament dispenser has a dispensing mechanism which is adapted to operate, upon each actuation thereof, to dispense medicament active from the medicament dose portion. Moreover, the mechanism has at least one power spring mechanism for winding the lid elongate sheet, wherein the at least one power spring mechanism has at least one spring having an inner end about which the spring unwinds, and at least one shaft at which the inner end of at least one spring is secured. Furthermore, the power spring mechanism tensions and peels a segment of lid elongate sheet peeled from a corresponding segment of blister elongate sheet upon each actuation of the medicament dispenser. Disclosed also is a method of assembling the aforementioned medicament dispenser.
