Needle insertion sensor
First Claim
1. A method of determining the quantity of medication delivered from an injection device into biologic tissue comprising:
- a) determining whether a needle is inserted into biologic tissue and if the needle is inserted into biologic tissue, measuring and recording the amount of medication injected, wherein when the needle is not inserted into biologic tissue, the amount of medication expelled through the needle is not recorded; and
b) repeating a) before medication is injected through the needle and summing the amount of medication injected through the needle into biologic tissue.

Abstract
This invention relates to a doser comprising a syringe (2) with a needle (3) which extends beyond the doser (1), which comprises an engagement face (4) in the vicinity of the needle so that the engagement face rests against the surface of the tissue into which the needle is inserted. Detector means (5) are provided on said engagement face to sample signals on the skin of the patient. The invention further provides means (13) for receiving external information related to health monitoring of a patient. This provides a doser that may record heart rate, EKG, BGM and hypo-alarm administered medicine. The doser may further be arranged to calculate an appropriate dose of medication on the basis of a number of acquired inputs.

12. A doser for determining the quantity of medication delivered from an injection device into biologic tissue, the doser comprising:
-
an injection device comprising a syringe with a needle, and an electrode, the injection device extending from the doser, an engagement face in the vicinity of the needle for engaging a surface of a tissue into which the needle is to be inserted, the engagement face comprising at least one additional electrode, wherein the electrodes are capable of detecting a physiological parameter in the tissue by generating electrical signals; electrical circuits adapted to generate and receive electrical signals and configured to measure the impedance between electrodes, and determine whether a needle is inserted into biologic tissue, such that if the needle is inserted into biologic tissue, measuring and recording the amount of medication injected, and when the needle is not inserted into biologic tissue, the amount of medication expelled through the needle is not recorded, and summing and recording the amount of medication injected through the needle into biologic tissue, wherein the electrical circuits are adapted to determine the quantity of medication delivered from the injection device into biologic tissue. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
