摘要:
In an arrangement for monitoring a connection between two elements (2, 3) of a medical tubing system, preferably an artificial respiration system, a first sensor element (6) is arranged on the first of both elements (3) and a second sensor element (5) is arranged on the second of both elements (2) in the area of the connection (1). At least one sensor element (6) has at least one signal generator which generates a warning signal when both sensor elements move away from each other beyond a predetermined distance.

A heart assistance device for the pulsatile delivery of blood is provided that includes a first pump chamber, a second pump chamber, and a pump. Both pump chambers each have a fluid chamber and a blood-carrying chamber. By means of the pump, each fluid chamber can be filled with a fluid or emptied thereof in such a way that an expansion or contraction of the fluid chamber takes place. During the expansion of the fluid chamber of one pump chamber, a compression of the blood-carrying chamber of the same blood chamber takes place. The pump is designed as a roller cell pump or vane pump.

A heart support device for pulsatile delivery of blood comprising a first and a second ventricle and a pump. Both ventricles comprises a fluid chamber and a blood-conveying chamber, wherein each fluid chamber can be filled with a fluid or emptied by way of the pump in such a way that an expansion or contraction of the fluid chamber occurs. In an expansion of the fluid chamber of a ventricle, a compression of the blood-conveying chamber of the same ventricle takes place, wherein a rigid pressure plate is disposed between a fluid chamber and the respective blood-conveying chamber, said pressure plate being able to move in the direction of the respective blood-conveying chamber.

摘要:
An implantable two-chamber system is for supporting the left ventricle of the heart. Each of the two pumping chambers (1, 1′) of the two-chamber system is ventricular shaped including an inlet (11) and an outlet (12). A pressure plate (2) is rotatably mounted externally in two arms (5) which are movably retained on the output shaft (9) of a drive unit (15) such that the center of motion (8) of the arms (5), which lies on the output shaft (9), is located on the side of the pumping chamber (1, 1′) facing away from adapters (4, 4′), and thus outside the pumping chambers (1, 1′). Each of the ventricular pumping chambers (1, 1′) is provided with a bulge (13) in order to reduce the resistance to fluid flow, this bulge (13) having a length ranging from 10 to 15 percent of the length of the pumping chamber.
摘要:
A cultivar of Miscanthus sinensis called ‘Tiger Tail.’ This cultivar is characterized by its long green leaves banded by yellow portions. It is tall in stature with thick, strict culms giving it an appearance of being tall and leafy throughout the growing season. The culms are green and less visible due to its color being similar to the leaf color.
摘要:
With a method for synchronization in a redundant communication system that includes a central participant and at least one further participant, at least one of the further participants being synchronized with the central participant, and, to this end, at least two telegrams containing synchronization information being transmitted by the central participant to the at least one further participant, if there is a transmission error involving a telegram containing synchronization information, it is still possible to carry out synchronization due to the fact that, based on the synchronization information contained in the at least two telegrams, resultant synchronization information is obtained and is used to synchronize the further participants with the central participant.
摘要:
A network station for a data network for receiving external data and for transmitting device-internally prepared data has a repeater for transmitting an external data packet received at a data input to a data output, a first data preparation unit for transmitting an internal data packet generated from the prepared data via the data output, having a switching device for interrupting the data path between the data input and the data output, a control unit that is connected to the switching device in order, in a first operating mode, to block the transmission of the received external data packet via the data output if the internal data packet is currently being transmitted via the data output by the data preparation unit, and to permit the transmission of the received data packet by the repeater via the data output if no internal data packet is currently being transmitted via the first data preparation unit.
摘要:
The latch needle in accordance with the invention comprises a needle tongue with an integrated spring that is configured as the functional element on the needle tongue. No separate tongue spring, whatsoever, need be accommodated in the saw slot. This novel needle concept is robust and suitable for high operating speeds.
