Abstract

A portable medical apparatus including at least a sampling assembly for providing at least one sample of a fluid in an object, a detector for determining at least one parameter of the fluid, an injector for performing at least one injection of an injection medium, and which are operable independent of each other for improved self-treatment of diseases such as diabetes. The portable medical apparatus has a single common housing for these components and a switch for changing between the sampling mode, the determining mode, and the injection mode. The apparatus also includes an actuator means for individually actuating the other components. The apparatus is an all-in-one device that facilitates the medical treatment process for patients, medical professionals or others.

Claims

1-32. -32. (canceled)

33. A portable medical apparatus comprising:

at least sampling means for, in a sampling mode, providing at least one sample of a fluid in an object,

determining means for, in a determining mode, determining at least one parameter of the fluid,

injecting means for, in an injecting mode, performing at least one injection of an injection medium, wherein the recited means are operable independent of or in co-operation with each other,

a single common housing for at least the sampling means, the determining means and the injecting means,

switching means for switching between functional modes including at least a sampling mode, a determining mode, and an injection mode, and

actuation means for individually actuating at least one of the sampling means, the determining means and the injecting means.

34. The portable medical apparatus according to claim 33, which further comprises a processing unit for controlling the functionality modes of the apparatus.

35. The portable medical apparatus according to claim 33, which further comprises adjusting means for adjusting at least one of the sampling means, the determining means and the injecting means according to individual needs and choice of functionality mode.

36. The portable medical apparatus according to claim 33, wherein the switching means comprises at least one sensor for registering switching between at least the sampling mode, the determining mode or the injection mode.

37. The portable medical apparatus according to claim 33, wherein the common housing is a hollow body having a first part capped by an exterior part of the actuation means, which first part opposite the exterior part is in operative communication with a second part optionally via at least the switching means, the second part has an operating end from which any of at least the sampling means, the determining means and the injecting means can be exposed to interact with either the object or one of the other means.

38. The portable medical apparatus according to claim 37, wherein the first part is rotatable in opposite direction to the second part along a longitudinal axis of the common housing.

39. The portable medical apparatus according to claim 37, wherein the apparatus comprises a display for displaying information to the user.

40. The portable medical apparatus according to claim 39, which further comprises a rotation ring in operative communication with at least one of the sampling means, the determining means, the injecting means, the actuation means, the processing unit, the storage means or the display alone or in combination.

41. The portable medical apparatus according to claim 37, wherein the second part is closed by an end part having at least one opening for exposure of at least the sampling means, the determining means and the injecting means.

42. The portable medical apparatus according to claim 37, wherein the operating end of the second part has illumination means for illuminating at least a part of the object during operation of the portable medical apparatus.

43. The portable medical apparatus according to claim 37, wherein at least the sampling means and at least a first part of the determining means are combined in a replaceable cartridge configured to be accommodated in the second part of the common housing.
