Abstract

A medical treatment administration system for delivering a medical treatment to a patient. The system has a medical device, an electronic processor coupled to the medical device, and a sensor coupled to the processor. The sensor receives one or more signals which it transfers to the processor. The signals can be derived from the patient'"'"'s physiological condition and/or the environment of the patient. The processor receives the signals and performs a calculation of the signal. Based on the result of the calculation, the processor regulates the distribution of medical treatment to the patient over a period of time.

Claims

1. A medical treatment apparatus for providing medication to a patient, comprising:

a medical fluid pump;

a controller in communication with the pump and having a control algorithm stored thereon;

a sensor for coupling to a patient to receive information from the patient concerning the physiological condition of the patient, the information being transferred from the sensor to the control algorithm; and

a light sensor that receives information about an ambient light environment from an environment of the patient, the information about the ambient light environment being transferred to the control algorithm,

wherein the control algorithm is adapted to process the information from both the sensor coupled to the patient and the sensor that receives the information about the ambient light environment to determine a circadian rhythm specific to the patient and control an amount and rate of the delivery of the medication to the patient based on the determined circadian rhythm of the patient by transmitting a command to the pump.

2. The medical treatment apparatus of claim 1, further comprising an input device for adjusting parameters of the control algorithm.

3. A medical apparatus for delivering a treatment to a patient, comprising:

a medical fluid pump for pumping a medical fluid to provide a medical treatment; and

a controller electrically connected to the medical fluid pump, the controller;

dynamically processing a first signal received from a first sensing device connected to the patient, and a second signal from a second sensing device, the second signal relating to information as to a temperature and light environment of the patient,

developing a feedback control based on a result of processing both the first and second signals to determine a circadian rhythm specific to the patient, and

controlling an amount and rate of the delivery of the medical treatment to the patient based on the determined circadian rhythm of the patient by transmitting a command to the pump.

4. The medical apparatus of claim 3, further comprising a control algorithm electronically connected to the controller, wherein the control algorithm processes the signals received from the sensing devices, and wherein the control algorithm develops a feedback control based on the result of processing the signals for the delivery of medication to the patient.

5. The medical apparatus of claim 4, wherein the control algorithm for the controller is downloaded to the controller.

6. The medical apparatus of claim 3, wherein the medical fluid pump pumps from a supply of medication.

7. The medical apparatus of claim 3, wherein the first signal is automatically obtained from a physiological condition of the patient without intervention from the patient.

8. The medical apparatus of claim 3, wherein the second signal is automatically obtained from the second sensing device without intervention from the patient.

9. The medical apparatus of claim 3, wherein the controller is housed with the pump.

10. The medical apparatus of claim 3, further comprising an input device coupled to the controller, the input device provided to allow an authorized user to manipulate the control algorithm.

11. The medical apparatus of claim 10, wherein the input device is a remote controller located at a second location distinct from a first location, and wherein the medical fluid pump is located at the first location.

12. The medical apparatus of claim 3, wherein the first sensing device comprises a vital signs monitor coupled to the patient, the vital signs monitor obtaining a signal from the patient.

13. The medical apparatus of claim 3, wherein the first sensing device comprises an activity sensor coupled to the patient, the activity sensor obtaining a signal from the patient.

14. The medical apparatus of claim 3, wherein the second sensing device comprises a light sensor coupled to the controller, the light sensor obtaining a signal based on the ambient light.

15. The medical apparatus of claim 3, wherein the second sensing device comprises an environmental sensor coupled to the controller, the environmental sensor obtaining a first signal based on an environmental factor of the environment of the patient and sending a second signal to the controller.

16. A medical treatment administration system for delivering a medical treatment to a patient, comprising:

a medical device for delivering a medical treatment to a patient, the medical device having a processor to regulate the distribution of medical treatment to the patient over a period of time;

a first sensor coupled to the processor, the first sensor receiving a signal from the patient concerning the patient'"'"'s physiological condition and transmitting the signal to the processor; and

,

a second sensor coupled to the processor and receiving a signal from an environment of the patient and transmitting the signal to the processor, the processor;

receiving the signals from the first and second sensors,

processing the signals to determine a circadian rhythm of the patient, and

regulating an amount and rate of the distribution of medical treatment from the medical device based on the circadian rhythm of the patient by transmitting a command to the medical device.

17. The medical treatment administration system of claim 16, wherein the first sensor is an input device that receives manual input.

18. The medical treatment administration system of claim 16, wherein the processor has a control algorithm that processes the signal from at least one of the first and second sensors.

19. The medical treatment administration system of claim 16, wherein based on the specific medical treatment to be administered to the patient, the processor processes the signal from one of the first sensor and second sensor.

20. The medical treatment administration system of claim 16, wherein based on the specific medical treatment to be administered to the patient, the processor processes signals from both of the first sensor and second sensor, and wherein the processor regulates the distribution of medical treatment from the medical device based on the cumulative result of the processed signals.
