Automatic lancet device and method of using the same
| Details |
Inventors: Ruppert, Norbert;
Assignee:
Primary Examiner: Thaler; Michael H.
Assistant Examiner:
Attorney, Agent or Firm:
An automatic lancet apparatus stores a plurality of sterile lancet needles which are loaded one at a time into an injecting position. After use of a needle, the apparatus ejects the used needle prior to loading a fresh needle. The needles include a cover over their tip ends which is automatically removed during loading. The loading operation also serves to reset the apparatus in preparation for injection. Once the needles are placed in the storage chamber, they are loaded, used, and ejected without further handling. |

DETAILED DESCRIPTION OF THE INVENTION Referring first to FIGS.
1A, 1B, and 1C, there is shown a simplified elevation view of a front end of an automatic lancet device in accordance with the teaching of the present invention.
The device comprises a casing 12 preferably formed of plastic or other lightweight material and having a lower portion 14 and an upper portion 16.
Between the lower portion 14 and the upper portion 16, there is provided a spacing in which there is positioned a slide member 18.
The slide member 18 includes a first slot 20 and a second parallel slot 22.
A plurality of lancet needles 24 is stored within the housing 12.
Spring device 26 biases the needles upward toward the slide member 18.
In the operation of the illustrative device, as the needles 24 are biased upward, one of the needles enters the slot 20, FIG.
1A, where it is captured by the slide member 18.
The slide member 18 is thereafter moved to the right hand direction into the position shown in FIG.
1B to transport one of the needles 24 into the location indicated at 28.
In this injecting location, the needle is captured by an injecting device 30.
In order to utilize the needle in the injecting position 28, the slide member 18 must be moved to the position indicated in FIG.
1C.
In so doing, the slide member rides upward over the needle in the injecting position by means of the inclined plane 32 formed on the slide member between the slots 20 and 22.
The slide member 18 is moved to the left until the slot 22 overlays the needle in the position 28.
In this position, the needle can be driven forward, i.
e.
, in a direction out of the plane of the paper, in order to puncture a finger of a person whose blood is to be tested.
Once the needle has been used, the slide member 18 is again moved towards the right hand edge into the position shown in FIG.
1B such that the used needle captured in the slot 22 is pushed laterally out of the injecting position.
By tipping the device towards its front surface after pushing slide 18 to the position of FIG
