摘要:
Die Erfindung betrifft eine Kammer, insbesondere eine Pumpenkammer, die eine plattenförmige erste Hälfte (10) und eine plattenförmige zweite Hälfte (12) umfasst. Die erste und die zweite Hälfte sind durch eine geschlossene Verbindungsnaht (20) flächig miteinander verbunden und wenigstens eine Hälfte weist wenigstens eine Öffnung (14) auf, die innerhalb der Verbindungsnaht liegt. Des Weiteren ist wenigstens die zweite Hälfte innerhalb der geschlossenen Verbindungsnaht derart thermisch verformt ist, dass sie relativ zu der Verbindungsfläche mit der ersten Hälfte gewölbt ausgebildet ist, so dass ein Hohlraum (30) zwischen der ersten und der zweiten Hälfte geformt ist. In einem zweiten Aspekt betrifft die Erfindung eine Pumpe die mindestens eine Kammer mit einem wie oben beschriebenen Aufbau umfasst. In einem dritten Aspekt betrifft die Erfindung ein Verfahren zu Herstellung einer wie oben beschriebenen Kammer.

The invention relates to a valve (10, 40, 60, 80, 100, 120, 150, 210), comprising a first valve element (12, 42, 62, 82, 102, 122, 152, 212) and a second valve element (14, 44, 64, 84, 104, 124, 154, 214), wherein the first valve element comprises a first carrier part (13, 43, 63, 83, 103, 123, 153, 213) which is made of plastic material and a first surface element (16, 46, 66, 86, 106, 126, 158) which is made of silicon or silicon oxide and is fastened to the first carrier part, and the second valve element comprises a second carrier part (15, 45, 65, 85, 105, 125, 155, 215) made of plastic material and a second surface element (18, 47, 67, 87, 107, 127, 159, 218) which is made of silicon or silicon oxide and is fastened to the second carrier part. The valve elements are arranged such that the first and second surface elements are seated in a planar manner against each other at least partially along an abutment surface, wherein the valve elements can be moved relative to each other in at least one direction parallel to the abutment surface of the surface elements. The first surface element has at least one first opening (20, 20', 50, 70, 70', 90, 90', 110, 130, 130', 162) and the second surface element has at least one second opening (22, 22', 52, 52', 52'', 72, 72', 92, 92', 112, 112', 132, 132', 163, 222), wherein the valve elements can be moved relative to each other in the at least one direction parallel to the abutment surface in at least one first position, in which the at least one first opening and the at least one second opening are in fluid connection with each other, and at least one second position, in which the at least one first opening and the at least one second opening are not in fluid connection with each other. The invention further relates to a device (200) comprising such a valve, to a use of the valve in a device, and to a micropump (400, 900), a nebulizer system (700) and a dosing/mixing device (500) comprising such a valve.

The invention relates to a peristaltic system (50), which comprises at least two pumps (30, 30') that can be separately actuated, each pump comprising a pump chamber (14) suited for receiving a fluid, a pump element (16) suited for suctioning and displacing a fluid into and from the pump chamber (14), two check valves (12, 12'), one of which (12) is in fluid connection with an inlet of the pump chamber (14) and the other (12') is in fluid connection with an outlet of the pump chamber (14), and a valve (18) which is closed in the idle state of the pump (30, 30') and in fluid connection with the check valves (12, 12'). The peristaltic system (50) further comprises a container (40) suited for receiving a fluid, the container being in fluid connection with an inlet of the one pump (30') and with an outlet of the other pump (30) and flexibly designed at least in some regions such that the volume of the container depends on the volume of a fluid that is received. The invention further relates to a fluid delivery device (100), a pipetting device and a sleeve, which use such a peristaltic system (50), and to a method for operating such a peristaltic system (50).

The invention relates to a method for joining a first component (10) to a second component (12), wherein the second component contains a thermoplastic material. The method comprises the following steps: bringing the first component in contact with the second component; heating the thermoplastic material of the second component at least in the vicinity of the first component to a temperature above the softening temperature of the thermoplastic material but below the decomposition temperature of the thermoplastic material; displacing the heated thermoplastic material such that an at least positive connection is created between the first component and the second component; and cooling the thermoplastic material to a temperature below the softening temperature thereof.
