摘要:
The present invention provides a puncture aid comprising a housing in which a lancet holder with a lancet is displaceably mounted, the lancet holder being connected to a spring element. The lancet holder has at least one bearing element and the housing has a support surface arranged such that the bearing element rests on the support surface in a first position of the lancet holder. A trigger unit is provided, actuation of which transfer the lancet holder to a second position by means of a relative rotational movement of the bearing element and the support surface, so that the bearing element falls from the support surface in the second position of the lancet holder, and the tensioned spring element at least partially relaxes and moves the lancet holder such that the tip of the lancet emerges from the opening of the housing. The puncture aid includes a blocking element which is arranged such that it blocks a relative rotational movement of the bearing element and the support surface with respect to one another after the trigger unit has transferred the lancet holder to the second position with the result that reuse of the puncture aid is prevented.

Blood withdrawal system for withdrawing blood for diagnostic purposes, comprising a housing with an outlet opening for the tip of a lancet, a lancet guide and a lancet drive. The lancet drive comprises a plural lever coupling mechanism, forming a connection between the drive element and the lancet during the puncturing movement and comprising two levers connected to each other via a first swivel joint, wherein one of the levers is coupled to the lancet with its end facing towards the lancet by means of a second swivel joint, and the second lever comprises a third swivel joint at the end facing away from the lancet. During the cocking movement, the freedom of movement of the lancet is limited in such a manner that the lancet tip does not protrude from the outlet opening.

The invention concerns a lancet system comprising a plurality of essentially needle-shaped lancets, a drive unit which has a drive element which is moved from a resting position into a lancing position in order to carry out a lancing process, a storage area to store the lancets, a withdrawal area to guide at least the tip of the lancet out of the system during the lancing process and a transport unit which can transport lancets from the storage area into the withdrawal area, wherein the drive element is arranged in such a manner that in the withdrawal area it can act on the lancet located there to carry out a lancing process and thus move the lancet from a resting position into a lancing position and wherein the system has a retraction device in the withdrawal area which can interact with the lancet located in the withdrawal area in order to move the lancet after completion of the lancing process from the lancing position into the resting position and it concerns a lancet magazine adapted to the system, a corresponding lancing device and a working process for the system.
摘要:
The delivery of fuel into the combustion chamber of a diesel engine is aided by blowing in an amount of compressed air which is small compared to the stroke volume of the diesel engine after the stream of fuel has been injected into the combustion chamber via the fuel nozzle. In this way fuel particles which would otherwise remain in the injection nozzle and considerably increase the hydrocarbon content of the exhaust are removed from the nozzle and burned, at the same time clearing the nozzle holes of any remaining fuel. The compressed air blown in after fuel injection will assist combustion of the red-hot particles of the fuel stream which have formed immediately beyond the nozzle.

摘要:
A circuit arrangement for monitoring the current supply of an electric consumer has a voltage regulator connected to an operating voltage that is variable over time and has a voltage monitor for switching on a consumer exclusively during the constant phase of the supply voltage. The voltage monitor is defined by a comparator at one input of which a reference voltage proportional to the regulator output voltage is present and at the other input of which a difference voltage picked up at the regulator output and exceeding a threshold value is present. A switch-on and switch-off signal can be take off at the comparator output.

A device for transmitting of binary data between a mobile data carrier (10) and a stationary station (11) is provided with a first resonance circuit (13) in the stationary station (11), whereby a switchable field effect transistor (25) is parallel switched to its condenser (17) by means of a switching pulse sequence, a second resonance circuit (12) in the data carrier (10) which is at least conductively coupled for a short time with the first resonance circuit (13). For the purpose of enlarging the inductively to be bridged distances between the resonance circuits (12,13) of data carrier (10) and stationary station (11) without impairing the operating safety during the data transmission the resonance circuit (13) in the stationary station (11) is designed in such a manner that its resonance frequency is about equal to the switching pulse sequence. The data transmission from the data carrier (10) to the stationary station (11) is performed by amplitude demodulation in the data carrier (10) and by amplitude demodulation in the stationary station (11). The data transmission from the stationary station (11) to the data carrier (10) is performed by frequency demodulation, whereby the frequency ratio is adjusted to 2:1.

A feed apparatus for elongated articles comprises a pair of endless helical springs having parallel spaced-apart reaches defining a generally horizontal transport path. The elongated elements are continuously displaced in a direction from an upstream end of the reaches to a downstream end thereof. Elongated articles such as gelatin capsules are loaded in random fashion onto the reaches at the upstream end so that at least some of these articles come to lie in the trough defined between these reaches, that is aligned parallel to the transport direction. The misaligned capsules fall off the upper reaches onto a return transport mechanism which automatically transports them back to the upstream end of forward transport mechanism.
