Abstract
This disclosure relates generally to an apparatus for creating a mechanically-wound infusion pump which can be used in a medical context to provide steady, reliable mechanical infusion amounts without relying on electricity and which can operate accurately in areas where electric power is not available or when ambulation is desired.
Claims15
An apparatus for a mechanical pump, comprising:
- a mechanical power reserve;
- a wheel train, wherein the wheel train comprises a series of gears and wheels through which an energy from the mechanical power reserve is transferred to a main infusion wheel;
- an escapement comprising an escape wheel, a balance wheel, a pallet fork, and a hairspring, wherein the escape wheel is attached to the wheel train, and wherein the hairspring is attached to the balance wheel to allow the balance wheel to swing in precise increments, and wherein the balance wheel is connected to the pallet fork which causes the pallet fork to move back and forth in precise increments, which in turn causes the escape wheel and the wheel train to move in precise increments;
- and,
- the main infusion wheel which powers the mechanical pump, wherein the main infusion wheel is turned by the wheel train.

An apparatus for a mechanically wound infusion pump, comprising:
- a housing;
- a winding crown;
- a mechanical power reserve, connected to the winding crown such that when the winding crown is twisted, power is stored in the mechanical power reserve;
- a wheel train by which power is transferred from the mechanical power reserve to a main infusion wheel;
- the main infusion wheel which powers the mechanically wound infusion pump;
- and,
- an escapement comprising an escape wheel, a balance wheel, a pallet fork, and a hairspring, wherein the escape wheel is attached to the wheel train, and wherein the hairspring is attached to the balance wheel to allow the balance wheel to swing in precise increments, and wherein the balance wheel is connected to the pallet fork which causes the pallet fork to move back and forth in precise increments, which in turn causes the escape wheel, the wheel train, and the main infusion wheel to move in precise increments, which allows for precise determination of the amount of fluid to be pumped, controlled by a rate of rotation of the main infusion wheel.
4 more elements
An apparatus for a mechanically wound infusion pump, comprising
- a housing;
- a winding crown;
- a mechanical power reserve connected to the winding crown;
- a wheel train connected to the mechanical power reserve by which a power is transferred from the mechanical power reserve to a main infusion wheel;
- an escapement which regulates a release of energy from the mechanical power reserve through the wheel train comprising an escape wheel, a balance wheel, a pallet fork, and a hairspring, wherein the escape wheel is attached to the wheel train, and wherein the hairspring is attached to the balance wheel to swing in precise increments, and wherein the balance wheel is connected to the pallet fork which causes the pallet fork to move back and forth in precise increments, which in turn regulates the release of energy from the mechanical power reserve through the wheel train;
- the main infusion wheel;
- and,
- wherein the main infusion wheel is turned by the wheel train and powers the mechanically wound infusion pump.
5 more elements
A method of pumping fluid without using electricity comprising;
- providing a mechanical power reserve;
- providing a means for storing energy within the mechanical power reserve;
- providing a pump;
- regulating a release of energy from the mechanical power reserve through the use of an escapement;
- transferring the energy from the mechanical power reserve through a series of gears to the pump;
- and,
- using the energy released from the mechanical power reserve to power the pump;
- wherein the escapement comprises an escape wheel, a balance wheel, a pallet fork, and a hairspring, wherein the escape wheel is connected to the series of gears through which energy is transferred from the power reserve to the pump, and wherein the hairspring is attached to the balance wheel to allow the balance wheel to swing in precise increments, and wherein the balance wheel is connected to the pallet fork which causes the pallet fork to move back and forth in precise increments, which in turn causes the escape wheel to move in precise increments, thus regulating the energy transferred from the power reserve to the pump.
