Electroosmotic pumps are fabricated from silica nanospheres [6] [7] or hydrophilic porous glass, the pumping mechanism is generated by an external electric field applied on an electric double layer (EDL), generates high pressures (e.g., more than 340 atm (34 MPa) at 12 kV applied potentials) and high flow rates (e.g., 40 ml/min at 100 V in a pumping structure less than 1 cm 3 in volume).
2010: Endo acquired generic manufacturer Qualitest Pharmaceuticals for $1.2 billion [8] 2011: Endo acquired medical device manufacturer American Medical Systems for more than $2 billion [18] [19] [7] 2013: Endo agreed to purchase Paladin Labs Inc for about $1.6 billion to gain access to the Canadian market as well as expand into emerging markets.
Using an osmotic pump to deliver drugs has additional inherent advantages regarding control over drug delivery rates. This allows for much more precise drug delivery over an extended period of time, which results in much more predictable pharmacokinetics. However, osmotic release systems are relatively complicated, somewhat difficult to ...

An electromagnetic pump is a pump that moves liquid metal, molten salt, brine, or other electrically conductive liquid using electromagnetism. A magnetic field is set at right angles to the direction the liquid moves in, and a current is passed through it. This causes an electromagnetic force that moves the liquid.
Peristaltic tube pump with two sprung rollers Peristaltic pump in motion. A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing.
Where ρ is the operating fluid density. One of the most important considerations, as a consequence, is to match the rated capacity of the pump with the required flow rate in the system that we are designing. Discharge Head, is the net head obtained at the outlet of a pump. For a centrifugal pump, the discharge pressure depends on the suction ...
When placed above or below the patient, the flow rate is typically increased or decreased slightly (head height effect). Filling the pump is done manually through a one-way valve using a syringe or peristaltic repeater pump. Elastomeric pumps are maintenance-free, run independently without any electronics, and are single-use disposable.
