A micropump, which in particular is a pump for a medicinal active substance and which may be an insulin pump or an analgesic pump, has at least one valve, which has a valve chamber, and has a pump chamber. At least one immobile structural element, which reduces the valve chamber volume, is provided in the valve chamber.

Micropump

A method for manufacturing a micropump, which may be for the metered delivery of insulin, multiple layers being situated on the front side of a first carrier layer, which has a front side and a rear side, and microfluidic functional elements being formed by structuring at least one of the layers. It is provided that the structuring of the at least one layer for manufacturing all microfluidic functional elements is exclusively performed by front side structuring. Furthermore, a micropump is disclosed.

Method for manufacturing a micropump and micropump

A method for producing porous microneedles () situated in an array on a silicon substrate includes: providing a silicon substrate, applying a first etching mask, patterning microneedles using a DRIE process ('deep reactive ion etching'), removing the first etching mask, at least partially porosifying the Si substrate, the porosification beginning on the front side of the Si substrate and a porous reservoir being formed.

Method for producing porous microneedles and their use

In an apparatus for storing and administering active substances, at least one transfer mechanism is provided, and a first reservoir that contains an active substance in dissolved form is also provided, the active substance being administered by way of the transfer mechanism. A second reservoir having the active substance in solid form is additionally provided in the apparatus.
