Abstract

This is a manual circular calculator for determining an appropriate insulin injection dosage to be taken with a meal. Preferably, the calculator has a pair of circular members which rotate around a single common center to allow calculation of the dosage. The front member includes a viewing panel showing an array of insulin injection dosage values that are printed on the rear circular member. The front member includes a series of measured blood glucose levels along a radius adjacent the viewing panel. The rear member typically has visible ingested carbohydrate values positioned along the outer perimeter of the member and, as noted above, a number of insulin injection dosage value arrays which become visible as one member is turned relative to the other. It is common that a physician would have a kit of these inventive devices, so that the appropriate one could be chosen depending on the insulin sensitivity, age, and size of the patient. In using the inventive calculator, a patient measures his or her blood glucose level and determines the weight of carbohydrates to be ingested at a particular meal. The carbohydrate ingestion is found on the outer perimeter of the back member of the device, the front member of the inventive device is turned so that an array of insulin values is visible, and the appropriate blood glucose level is read along the radius of the front circular member. The corresponding insulin injection dosage is seen in the window.

Claims

1. A manual circular calculator for determining an appropriate insulin injection dosage to be taken with a meal, comprising

a.) a first circular member having a center, a radius, and a viewing panel extending from said center, measured blood glucose levels along a radius adjacent the viewing panel, and

b.) a second circular member having a center, a radius larger than the radius of the first circular member radius, a multiplicity of insulin injection dosage value arrays, each array containing a number of insulin injection dosage values displayable in an area visible in said viewing panel and said displayable insulin injection dosage values corresponding to said measured blood glucose levels positioned adjacent the viewing panel, and wherein each insulin injection dosage value array further corresponds to an ingested carbohydrate amount positioned exterior to the first circular member,

wherein said first circular member center and said second circular member center generally coincide and said members are rotatable about said centers with respect to each other to display an array of insulin injection dosage values in said viewing panel corresponding to an ingested carbohydrate amount and measured blood glucose levels as said members are rotated with respect to each other.

2. The calculator of claim 1 wherein said multiplicity of insulin injection dosage value arrays are selected from the group consisting of the set of arrays provided by each of Tables 1-15.

3. The calculator of claim 1 wherein said insulin injection dosage values have values from 0-40 units.

4. The calculator of claim 3 wherein said insulin injection dosage values have values from 0-3 units.

5. The calculator of claim 1 wherein said viewing panel is wedge-shaped.

6. The calculator of claim 5 wherein said viewing panel is open.

7. The calculator of claim 5 wherein said viewing panel is a transparent material.

8. The calculator of claim 1 wherein said first circular member has a front surface having foodstuffs pictured thereon.

9. The calculator of claim 8 wherein said pictured food corresponds to the insulin sensitivity of a patient.

10. A set of the calculators of claim 1 wherein at least some of said calculators have differing arrays of insulin injection dosage value arrays.

11. The set of the calculators of claim 10 wherein at least some of said differing arrays of insulin injection dosage value arrays are selected from the group consisting of the set of arrays provided by each of Tables 1-15.

12. A method for determining an insulin injection dosage to be taken with a meal using the calculator of claim 1, comprising the steps of:

a.) aligning the first circular member by rotation with respect to the second circular member such that a chosen ingested carbohydrate amount positioned exterior to the first circular member is positioned to display an insulin injection dosage value array in said viewing panel,

b.) selecting a measured blood glucose levels from along a radius adjacent the viewing panel, and

c.) determining a corresponding insulin injection dosage value adjacent said selected measured blood glucose level.

13. The method of claim 12 further comprising the step of selecting the calculator of claim 1 from the set of claim 10.

14. The method of claim 12 further comprising the step of selecting the calculator of claim 1 from the set of claim 11.
