Abstract

There is provided a portable medical device for injecting insulin comprising a blood glucose meter, a first display that is capable of displaying the blood glucose content of a blood sample as determined by the blood glucose meter, means for injecting insulin in a patient comprising means for setting the amount of insulin to be injected comprising a second display that shows the amount of insulin to be injected characterized in that the device comprises a deactivation means that automatically switches off the first display.

Claims

1. A portable medical device for injecting insulin comprising

a. a blood glucose meter,

b. first display that is capable of displaying the glucose concentration of a blood sample as determined by the blood glucose meter,

c. means for injecting insulin in a patient comprising means for setting the amount of insulin to be ejected by the device, comprising a second display that shows the amount of insulin to be ejected

wherein the device comprises a deactivation means that switches off the first display when the means for setting the amount of insulin to be ejected is set to a setting that permits the ejection of insulin.

2. Device according to claim 1 where the second display is a mechanical display.

3. Device according to claim 1 where the first display is an electronic display.

4. Device according to claim 1 where the deactivation means comprises a sensor that senses when the means for setting the amount of insulin to be ejected is set to a setting that permits the ejection of insulin.

5. Device according to claim 4 where the sensor is a position sensor.

6. Device according to claim 5 where the position sensor is connected to a processing unit that controls the first display.

7. Device according to claim 1 where the drive mechanism of the means for injecting insulin is powered by the user.

8. Device according to claim 1 where the first display is automatically switched on when the means for setting the amount of insulin to be ejected is set to a setting that does not permit the ejection of insulin.

9. Device according to claim 1 where the angle between a line that is perpendicular to the surface of the first display and a line that is perpendicular the surface of the second display is at least 60°

.

10. Device according to claim 1 has a housing and the device additionally comprises a site for connecting a lancet located in one end of the housing and where the means for injecting insulin includes a cartridge housing for receiving an insulin cartridge where said insulin cartridge can be connected to an injection needle, said injection needle being located, when connected to the cartridge, in the opposite end of the housing and where an injection actuator is located in the same end of the housing as the site for connecting a lancet.

11. Device according to claim 10 where the first display is located on the housing approximately in the middle between the site for connecting a lancet and the site for connecting the injection needle on the insulin cartridge.

12. Device according to claim 10 where the angle between the lancet and the injection needle is about from 160°

to −

220°

.

13. Device according to claim 1 further comprising a site for connecting a lancet and where the blood glucose meter comprises an test strip port such that the angle between the test strip, when inserted into the test strip port, and the lancet is from 45°

to 135°

.

14. Device according to claim 1 where the blood glucose meter comprises a test strip port and where the angle between a test strip, when inserted into the test strip port, and an injection needle, when attached, is from 45°

to 135°

.
