Embodiment Construction

[0037]FIG. 1 shows a schematic cross-sectional view of a micro-dosing pump 1 . The micro dosing pump basically has a durable unit 23 and a disposable unit 24 . The disposable unit 24 has a pump chamber base 19 with the pump chamber 2 arranged therein. The pump chamber base 19 can be formed, for example, by injection molding from polycarbonate, polypropylene, PVC, polystyrene, polytetrafluoroethylene (Teflon) and / or PFPE. However, other materials are also suitable for the manufacture of the pump chamber substrate 19, such as metal and / or semiconductor materials. The flexible membrane 3 is fluid-tightly connected to the pump chamber base 19 on one side with few bases. The pump chamber base 19 has at least one fluid line 4 which enables fluid to flow into and out of the pump chamber 2 of the pump chamber base 19 . Furthermore, a rotatable valve disk 6 is arranged in the pump chamber 2 . The rotatable valve disk 6 has a fluid passage opening 17 and is arranged above the fluid ...

Abstract

The invention relates to a micro-dosing pump and a method for producing the micro-dosing pump. The micro-dosing pump includes a pump chamber substrate, a flexible membrane, a fluid line, a valve disk, a magnetizable actuator disk, and a drive unit. The pump chamber substrate has a pump chamber. The flexible membrane is on a first side of the pump chamber substrate and covers the pump chamber in a fluid-tight manner. The fluid line is on a second side of the pump chamber substrate such that fluid can enter and leave the pump chamber. The valve disk, arranged inside the pump chamber, has a fluid through-opening and is configured to close the fluid line by rotating and to open it via the through-opening. The actuator disk is coupled to the valve disk such that rotating the actuator disk rotates the valve disk. The drive unit has a pump plunger configured to move the membrane for suction or ejection of fluid and to rotate the actuator disk.

Description

technical field [0001] The invention relates to a micro-dosing pump (micro-dosing pump) and a method for producing a micro-dosing pump. Background technique [0002] Micro-dosing pumps are often complex and expensive to produce, if at the same time high demands are placed on their own safety functions. In the case of insulin pumps, for example, it must be ensured that inadvertent insulin administration cannot occur under any circumstances, since this could have serious health consequences for the patient. Here, therefore, the administration of the required dosage with high precision must be ensured in any case. [0003] Although the modified axial piston pump based on die-cast components in EP1966490B1 promises to meet all safety features at relatively low manufacturing costs, the degree of miniaturization is somewhat limited here because it involves a three-dimensional arrangement of 3D individual components , these 3D individual parts must also be three-dimensionally str...
