Artificial pancreas
First Claim
1. Artificial pancreas of the type comprising a means for automatically and periodically withdrawing blood samples from the body of a patient (M), means for measuring a level of glucose present in the blood sample (glycemia), means (8) for injecting a dose of insulin or glucose into the body of a patient, and means (u) for calculating and data processing which determines an amount of insulin or glucose to be administered to the patient as a function of the glucose level measured by the measuring means and for controlling the injecting means (8) in a manner corresponding to the amount of insulin or glucose to be administered, characterized in that measurement of glycemia is carried out by reading a color of a reactive zone (z) of a strip (b) reactive to glycemia, the measuring means comprising to this effect:
- a) means (3) for distributing strips (b);
b) means (4) for depositing a blood droplet supplied by said withdrawing means on the reactive zone (z) of a strip (b);
c) means (5) for wiping the zone (z);
d) means (6) for optical reading of the color taken by the zone (z);
e) means (7) for removing the strip; and
f) means (1,
2) for automatically conveying the strips (b) individually from means to means (3, 4, 5, 6,
7), wherein said measuring means is mounted on a common deck (100).

Abstract
The artificial pancreas comprises a unit for automatic and periodical withdrawal of blood samples from the body of a patient (M), a unit for measuring the glycemia of this sample, a unit (8) for injecting insulin or glucose, and a unit (U) for calculation and data processing in order to determine the amount of insulin or glucose which is to be administered to the patient as a function of the glucose level measured by the measurement unit, and to control consequently the injection unit (8). This artificial pancreas is characterized in that the measurement of the glycemia is effected by reading the color of a strip reacting to glycemia, the measurement unit comprising to this effect: a) a strip distribution station (3); b) a station (4) for depositing a blood droplet on the strip; c) a station (5) for wiping the strip; d) a station (6) for optical reading of the color taken by the strip; e) a station (7) for removing the strip; f) a transportation device (1, 2) for conveying the strips individually from station to station.
