Description

System for infusion of medication
This invention relates to a system for infusion of medication to a patient, where the system consists of a wet part, a control part and a personal digital device. The wet part and the control part forms a infusion device, carried by a person, who has the infusion means planted on a suitable place on the body for infusion of the medication, and the personal digital device is able to radio communicate with the infusion device.
Persons who needs medico treatment .for a long period, like diabetic patient who needs infusion of insulin, can today have a portable infusion device, which will infuse the medication in small splashes at small intervals, into a suitable place in the body. This device is often refereed to as an infusion pump, and the patient refereed to as pump patients. The infusion device has a control part, which is connected mechanically to the infusion device, and which control part is used by the patient to communicate information's to the infusion device.
As the control part is connected to hoses and medication container, the patient will more or less have to expose his sickness, if he in public places has the need for communicate information's to the control part. A remote device is therefore offered together with the infusion pump, by which the patient is able to give little information like a bolus rate of infusion, if such is needed. This remote device is only capable of giving this few information's, and is as such an additional personal device to be carried. It is an object of this invention to reduce the numbers of personal devices the patient has to carry. This object is achieved by using a general digital device as the personal digital device, which in addition can radio communicate with the infusion device.
It is of advantage that the person is able, via the personal digital device, to interfere with the rate of infusion of medication the infusion device discharge. Hereby is it possible for the patient to give a bolus rate of infusion, using a common known digital device, and without anyone can notice that the person suffers from a sickness .
It is a further advantage that the personal digital device is able to receive information' s concerning the infusion of medication, and the infusion device itself, from said infusion device. Hereby is it possible to record information's about the status of the system, and about the infused rate of medication, and to document the results .
It is of particular advantage that the personal digital device is a portable device. Hereby is achieved that the patient is able to control the rate of infusion any time and any place, without the need for additional equipment.
A particular advantage is if the system further comprises a sensing device for sensing the parameter in the body, which is to be controlled by the infusion of medication.
The sensor can then communicate the value of the sensed parameter to the infusion device, whereby infusion of medication can be controlled in accordance with the value of the sensed parameter. Hereby is achieved that the infusion device with sensor is able continuously adjust the rate of infusion of medication to the need, and a more accurate rate of infusion can be obtained.
The invention will now be described in details with references to the drawings, showing:
Fig . 1 A person who needs medico treatment .
Fig . 2 An infusion device for infusion of medication.
Fig . 3 A personal digital device for control of the infusion device.
Fig . 4 Wet part of an infusion device, containing the medication.
Fig . 5 Control part of the infusion device, containing actuators, control and radio communication. - Fig. 6: A sensor for sensing parameter in the person, which is to be controlled by the medication. - Fig. 7: System for infusion of medication to a person, based on radio communication between the elements of the system.
In figure 1 is indicated a person as position 1, who needs medico treatment. This could be a diabetic patient, who needs to balance the level of glucose in the blood by infusion of insulin, but is not limited to this purpose.
In figure 2 is shown an infusion device, which is to be carried by the person 1. The infusion device consists, among others, of a medication containing part 2, build of the parts in figure 4 and 5.
The part in figure 4 is to be refereed to as a wet part 12, and consist of a housing 17 with a flexible hose 15, ending in a connection part 16. Inside the housing 17 medications are contained, indicated as position 13, and means for dosage the medication, indicated as position 14 The wet part 12 could be either a disposable part, or a rechargeable part. In case the wet part 12 is a disposable part, all basic control an actuation means are placed in a control part, 11 at figure 5. The disposable part is hereby held as cheep as possible.
The part 11 is formed as two shell parts 18 and 19, hinged together at position 20. The wet part is placed in one of the shells 18 and 19, whereby the hose 15 fits the two cutouts 21. When the wet part 12 and the control part 11 are connected to each other, they forms an infusion device which is able to infuse medication, and able to perform radio communication. The radio communication is in order to give the patient the ability of adjusts the rate of infusion of medication, or to give the infusion device needed information' s in order to perform the correct rate of infusion. Those information could be given directly on the control device 11, but for the patient it is more convenient to give the information's as radio communication, whereby the information's could be given at public places without actually showing the infusion device .
The infusion device 2 in figure 2 further consists of a connector part 5, a flexible hose part 6 and a port of entry 4. The port of entry 4 is a plaster 7, fixed to the hose 6, and a needle in which the hose ends. The port of entry part 4 is placed on a suitable place on the body, with the needle sticking through the skin, and is held in place by the plaster 7. Medication is now able to flow from the wet part 12 , under control of the control part 11, through the connector 5 and the hose 6, and into the patient through the needle 8. The connector part 5 is for the purpose of disconnecting the infusion device 2 from the port of entry 4, either during personal sanitation or during replacement of either port of entry 4 or infusion device 2.
Now having described the infusion device and the possibility of radio communication, the device, which communicate, with the infusion device is to be described. In figure 3 is shown personal digital device, like a portable electronic calendar or a mobile phone. The personal digital device 3 has a display part 9, and buttons whereby the person is able to communicate with the device 3.
The personal digital device 3 further contains the possibility of performing radio communication with the infusion device 2, and it contains soft ware fitted to the infusion device. It is hereby possible for the patient to communicate information's to the infusion device 2, and to get information's about the infusion device 2 from same. The patient have no need for an additional digital device to communicate with the infusion device, but can simply have a by him already existing digital device adopted also to be able to communicate with the infusion device.
The infusion of medication for the purpose of maintaining a certain level of a specific parameter in the body, like glucose in blood, requires at least a frequent measurement of the actual level. Information's about this frequently measured level can be communicated to the infusion device 2 by the patient 1, by using the personal digital device 3. This is indicated as figure 7, where the radio communication to the infusion device 2 from the personal digital device 3 is indicated as position 25, and the radio communication from the infusion device 2 to the personal digital device 3 is indicated as position 26. The infusion system could further comprise a sensor in or at the patient, for the purpose of measuring the level more continuously. This sensor is indicated as position 22 in figure 7, where it is able to communicate the measured level to the infusion device 2, via radio communication 27. The infusion system will then form a closed loop control system, where the personal digital device 3 will be the device from where the control parameters for the closed loop control is set, and will be the device to which information's about the closed loop control is send. The infusion device 2 will then contain a limited memory, in which information's are stored, until they are loaded to the personal digital device 3.
The sensor 22 is shown in figure 6, where position 24 indicates the sensing area, which is in contact, continuously or frequently, with the compound or tissue in which the level is to be measured. Position 23 indicates the housing of the sensor, with in case of an implantable sensor should be of a biocompatible material or have a biocompatible coating.
The personal digital device might preferably be portable, but could as well be stationary device. Only must the communication between infusion device and personal digital device occur under safe conditions, whereby is to be understood a communication which not can be interfered by other communications.
