Abstract

A therapeutic treatment device, system and method for improving administration of a temperature sensitive drug into a tissue on the body of a patient at a drug injection site are disclosed. The device includes a treatment element with a controllable heating element in temperature communicative contact with the tissue adjacent to the drug injection site. The controllable heating element is configured to heat the tissue adjacent to the drug injection site to a controllable temperature but does not heat the injected drug above a predetermined limiting temperature, above which degradation of the injected drug may occur.

Claims

1-33. -33. (canceled)

34. A treatment device for effecting the adsorption of drug in tissue comprising:

a processor; and

a treatment element comprising a disposable part, a reusable part, at least one identification element configured to determine prior use of the disposable part, and an injection area for administering a plurality of injections of a drug into an injection site of a tissue at a location on the body,

wherein the treatment element is

controlled by the processor,

configured to apply a treatment to the tissue at or adjacent the injection site during at least one of before, during and after injection of the drug for a predetermined period of time, and

the treatment is configured to improve the pharmacokinetic and/or pharmacodynamic properties of the injected drug.

35. The device according to claim 34, wherein the treatment element includes a heating element controlled by the processor and the treatment comprises heat, and the tissue is heated to a predetermined temperature which is less than a predetermined limiting temperature above which the drug degrades.

36. The device according to claim 35, further comprising a temperature sensor configured to provide one or more signals corresponding to the temperature of the tissue at or adjacent the injection site, wherein based on the temperature of the tissue, the processor controls the heater to stabilize heating of the tissue to the predetermined temperature.

37. The device according to claim 34, wherein the reusable part includes the processor and an energy source for at least providing power to the treatment element, and wherein power from the energy source to the treatment element is controlled by the processor.

38. The device according to claim 34, further comprising a temperature sensor provided by the reusable part, wherein the sensor is configured to provide one or more signals corresponding to the temperature of the tissue at or adjacent the injection site to the processor.

39. The device according to claim 34, wherein the at least one identification element includes at least one of an electrically-burnable element, an EPROM chip, an RFID chip, a barcode, and a single-use mechanical attachment.

40. The device according claim 34, wherein the treatment element includes at least one marker indicating the location of the injection site.

41. The device according to claim 34, wherein the treatment element includes an identification mechanism configured to identify a time when the drug is injected, and wherein based on information provided by the identification mechanism, the treatment element is configured to automatically apply the treatment.

42. The device according to claim 34, wherein the processor is configured to control the treatment element to apply treatment according to a predetermined treatment profile.

43. The device according to claim 42, wherein the predetermined treatment profile corresponds to at least one meal type or at least one drug dose.

45. The device of according to claim 34, wherein the treatment element is configured for positioning adjacent the location.

46. The device according to claim 34, wherein the treatment element includes a detection sensor configured to detect injection of the drug into the tissue and provide one or more signals of such detection to the processor for effecting activation of the treatment element.

47. The device according to claim 41, wherein the identification mechanism comprises at least one of:

a skin sensor configured to sense folding of skin, a pressure sensor disposed on the treatment element, a pressure sensor disposed on a marker arranged on the treatment element and configured to mark a spot for placement of a finger during injection, and a proximity sensor configured to sense proximity of a device for injecting the drug into the tissue.

48. The device according to claim 34, further comprising a memory having stored thereon at least one predetermined treatment profile dependent on a dosage and a type of the drug being injected access by the processor for controlling the treatment element according to the profile.

49. The device according to claim 48, wherein the treatment device includes a measurement mechanism configured to provide one or more signals deterministic of a volume of the drug stored in the tissue at the location to the processor, and wherein the processor is further configured to adjust application of the treatment based on one or more signals.

50. The device according to claim 49, wherein the measurement mechanism comprises an impedance sensor configured to measure the impedance of the tissue at the location.

51. The device according to claim 34, wherein the treatment device further comprises an alert mechanism configured to provide an alert corresponding to a time of a next injection.
