Lancing device for taking blood

The invention relates to a lancing device for taking blood with an exchangeable one attached to the end of a spring-loaded punch Lancet.

ge lancing devices with built-in knives, needles or lancets have long been known. In practice, however, one had to experience that with lancing devices this Design often infections and pathogens (especially viruses) are transmitted. This common sequel cannot be removed with normal disinfection. Heat sterilization alone is safe but not feasible due to time constraints.

The use of lancing devices has therefore recently been abandoned with a fixed lancet completely gone and used individual lancets packed in sterile paper, which after the

Puncture (e.g. in the finger) should be thrown away as soon as possible.

With this method of piercing by hand, it largely depends on the skill of the smoker, how deep the Puncture takes place. Another disadvantage of this method is that each lancet has to be removed from the packaging by hand must remove, and the sterility can very easily be violated.

The object of the invention is to construct a lancing device which does not have the aforementioned disadvantages and provides a new sterile lancet for each lancing process.

The lancing device according to the invention is marked for this purpose through a magazine that can be inserted into the lancing device with individually sterile packed lancets and a with the driver connected to the punch, on which the respective foremost lancet in the magazine rests in such a way that when actuated of the stamp, the lancet tip pierces the sterile packaging.

In this way, any touch of the lancet by hand before the piercing process is reliably avoided, as a result of which the transmission of infections and pathogens is largely prevented,

Various solutions are conceivable for the interaction of the driver with the individual lancets in the magazine.

According to a preferred embodiment of the Ex f inäung, the driver has two claws which pull up the packaging of the adjacent lancet when the stamp is tensioned, whereby the lancet tip pierces the packaging. In the highest position of the punch, a pin of the driver engages in a notch in the lancet, so that the lancet is taken along when the punch is triggered. A magnet on the driver gives the lancet the necessary hold. After the lancing process, the lancet is withdrawn by hand or by means of an ejector.

In another from of the invention, the guide form the magazine contains a strip with individual adjacent lancets, which are each designed approximately tack-like manner with wide head. Each time the punch is tensioned, the magazine tape is conveyed by means of a friction wheel or the like so far that a new lancet lies in front of the punch. After triggering, the descending punch hits the broad head of the lancet and thereby pushes its tip through the pack and into the finger or the like.

E1.n general example of the invention is described below with reference to the drawing. Here are:

In a housing 5 there is a plunger 1 which is pressed downward by a helical spring 2. For tensioning, the punch 1 is pulled up so far that its nose k engages behind a corresponding projection of the housing; by means of a trigger bar 3, the nose k can be pressed into the housing, as a result of which the stamp jumps downwards at a considerable speed.

At the lower end of the housing 5 there is an exchangeable one Magazine 8 closed by a removable cap 11 in

its location is secured. Between the cap 11 and one front opening of the magazine 8 there is a compression spring 9, which the contents of the magazine forward against pushes the driver 6.

The magazine 8 contains a plurality of individually packaged lancets 12 which have a notch 13 at the upper end and a sharp point Ik at the lower end. Every

The arranged at the lower end of the stamp 1 driver has a pin 21 which in the upper notch 13 of the adjacent lancet 12 can engage, and two lower claws 22, which when the stamp 1 is pulled up from Place it against the stiffeners 16 of the packaging 15 at the bottom. As the punch continues to be tensioned, the claws 22 pull

the lower part of the packaging with the stiffeners 16 upwards, whereby the point Ik penetrates the thinner middle part of the packaging between the stiffeners 16. Only when the plunger has been raised so far that the lancet tip Ik is exposed does the pin 21 engage in the notch 13. As a result, the spring 9 can advance the lancet 12 until it is firmly inserted from above and below through the pin 21 and the claws 22 is held and is also fixed by a magnet 7 embedded in the driver 6.

If the punch 1 is then triggered by means of the trigger 3, it strikes downward under the action of the tensioned spring 2 and takes the lancet 12 and its packaging with it, so that the exposed tip Ik enters the patient's skin on which the lancing device is placed is penetrates.

After the lancing device has been lifted off, the used lancet can be withdrawn by hand or by means of an ejector (not shown). At the same time, the next lancet 12 located in the magazine 8 is pushed in by the spring 9, on the end face of which there is a pressure plate Zk.
