Definitions

  • UMTS/GPRS with a server, and from there to inform concerned parties with web, wap or SMS/MMS.
  • the point to point communication is done with a single another point only, a server, monitor presenting data of sensors, or pump programmer, which does not solve the complex problem of Home Care as discussed later.
  • the pump can send copy of the communication to the server (if it exists), but it can be programmed directly from a mobile terminal without using the Internet, for safety and simplicity reasons, or to inform nurse in charge directly, possibly by
  • SMS which may also make a minimal, without server network.
  • the need to a minimal network comes from the lower cost if data are small, an independent network done from a Home Care Provider on his own, fear of information stolen from Internet.
  • a connection mobile terminal to mobile terminal is a point to point connection, while server emission to many receivers is a beam. Emission from mobile phone to server is point to point.
  • the pump-diagnostic system is a different kind of server, for different contact points and different communication protocols
  • the nurse is visiting the patient kilometers far from her, to change a drug reservoir, a battery, adapt infusion rate to evolving health conditions, so that patient does not feel pain (in PCA), or restore infusion after an alarm.
  • Infusion of drugs with pumps has therapeutic and side effects. Measuring both, with implantable and extra-corporeal sensors, and monitoring therapy progress from distance, gives the opportunity to have automatic and semi-automatic infusion profile adjustment, with a doctor's digital signature, to increase therapeutic and reduce side effects.
  • An infusion titration path risk analysis ends up often on the doctor's decision need. The present invention eases the implementation of this information, decision, and immediate infusion titration process, while keeping event log record with who did what information.
  • the present invention preferably uses minimal, point to point momentary communication, between therapy/diagnostic system and monitoring personnel, but also classic communication with server, communication address book and procedure to update it, and communication priority list.
  • Communication may use means such as mobile terminal in any integration level
  • GSM box or mobile phone
  • modem and PSTN line or pager.
  • Siemens
  • At least Wavecom and Sony Ericsson have integrated TCP/IP protocol for easy GSM-GPRS /UMTS data connection with a server.
  • the service is SMS, MMS, GPRS, email, pager, or any other type of communication which arrives at the nurse on the move.
  • the waveforms of a sensor can be sent as images generated locally from raw data, and attached on an MMS message. So the doctor can receive directly from the patient's system an MMS with a cardiogram diagnosed locally as severe arrhythmia and he can decide what to do.
  • the above are working with other cellular telephony standards used in the US and Asia, 4 band cellular phones are a commodity today.
  • the communication protocols at user layer and the address book can be programmed on the microprocessor of the OEM card cellular phone with tools and operating system provided by the supplier.
  • the medical part i.e. data are provided from a serial port connection with the medical device.
  • the mobile telephone acts as a local area network server, with serial or RF connection with the pump, or be integrated in the pump, and RF connection with other sensors as referred in the art.
  • the inventive step here is in the evolution of the phone as a node of local communication with use of address book and protocol of updating them, and communication not only with one server but with many interested parties, using several communication paths (SMS, MMS, TCP/IP, email etc.)
  • Therapy system in present invention could be an infusion pump, or a pill handling system, releasing a pill at the right moment, and the diagnostic system could incorporate an ECG analyzer a pressure monitor, a pulse oximeter, a weighing scale etc.
  • the diagnostic system could be in form of a chest belt, known in the art for athletes training, having 3 conductive rubber contacts, with the difference that in the present patent the ECG is analyzed using advanced diagnostic algorithms, issuing alarms in case of tachycardia, bradycardia, and some dangerous arrhythmias. For each arrhythmia, bradycardia or tachycardia, there are one or more limits, having different medical use. Some alarm, other just record the event for a statistical use.
  • the belt incorporates means for transmission and battery in a full telemedicine system.
  • the belt can contain a reflective pulse oximeter using 2 or more LEDs and a photodiode, known in the art for measuring pressure of oxygen, and carbon dioxide; and the system so can also have limits on hypoxemia, hypercapnia.
  • the pulse oximeter sensor may have the form of a behind the ear device, with optical part on the lobe.
  • the diagnostic system can be a wrist bracelet, which measures at a time interval or on demand arterial pressure, in parallel with a pulse oximeter measuring blood flow initialization for pressure measurement as known in the art, but also saturation of oxygen, and pulse rate.
  • the tightening the wrist system can be mechanical as a belt or pneumatic. From the pulse oximeter, uninterrupted work, we measure precisely cardiac rhythm, and from this, arrhythmias; bradycardia and tachycardia can so be detected. The artifact noise is rejected with special algorithms known in the art.
  • a preferred minimal embodiment is a therapy/ diagnostic system with internal or external telemetry system, which could be part of a mobile phone, in OEM card form, or chip, which sends and receives SMS /MMS messages from other mobile phones.
  • An infusion pump part of the said therapy/ diagnostic system in serial connection with the phone, sends through it information messages in SMS (or MMS or email) form, eventually on alarm event, or at regular intervals, or on demand as an answer to a call (unanswered) from shift nurse. Same is done from said diagnostic system, which monitors some medical health parameters. Diagnostic system connects to the said communication system, with a wireless local area network, as referred in the prior art. Low power consumption chip and special low power light communication protocol are used, some chips today have protocol in hardware (Nordic). The mobile phone of the nurse on shift to which shall be sent an eventual message, is updated in the memory of said therapeutic / diagnostic system via a call or a message from the nurse.
  • a new nurse on relaying shift sends a non answered call and the nurse phone number is stored in FIFO memory, replacing previous shift nurse phone as SMS and MMS recipient.
  • the call may be a message with a code in it.
  • the relay can also be done through the server to all patients' (communication systems) the nurse is in charge. More than one phone numbers can be put in lists, for doctor, and other interested parties.
  • the pump function and diagnostic means do not send continuously data, but on event, the connection can be momentary, as an SMS and so can be sent to more than one recipients.
  • the mobile therapy/diagnosis system can be programmed, configured and get limits to alarm/pre-alarm, get updated address book, from a PC, or SMS /MMS, email, GPRS data.
  • the server IP address and socket, APN -application server of the communication company can be stored in the system's memory, via a PC or
  • SMS mobile
  • the mobile (SMS) updating of addresses and functional characteristics has an advantage vis a vis PC use, to send update from distance, while a server is not possible to introduce a new SIM card, as on the mobile phone side, there is no information on which network to connect.
  • SMS update of info can be also automated from the server when it has no other way to "find" the therapy/diagnostic system by lack of SIM card characteristics on the mobile side. This procedure is another inventive step over prior art.
  • the system infusion pump uses two new in the art alarms as below.
  • the alarm does not sound on the pump if it is so configured.
  • the pump calculates overall basal rate plus bolus delivery as mean rate of last hours, and calculates at what time it will end the remaining in the reservoir drug. If this occurs during the night, it emits alarm at the evening, so that nurse can change the reservoir before the night, and reduce nuisance and costs of both patient and nurse.
  • the limit to alarm can be programmed in the pump as needed by the doctor, to have an indication if analgesia is achieved. Because the pump is far away, the doctor does not have an indication of the pain treatment. The alarm gives this warning, so if it is possible, to increase the dose, and achieve analgesia. The dose can be adjusted over the air.
  • TPN infusions may produce hyperkalemia, and hypermagnesemia with arrhythmias, so TPN infusion stops and an alarm to therapy watching personnel is sent. Same in Epoprostenol (Flolan) infusion to people with primary pulmonary hypertension, not adhequate infusion rate may reduce blood oxygen levels, and people with this chronic disease can die.
  • Epoprostenol (Flolan) infusion to people with primary pulmonary hypertension not adhequate infusion rate may reduce blood oxygen levels, and people with this chronic disease can die.
  • a therapy/diagnostic system When a therapy/diagnostic system receives a non answered call, it sends preferably SMS (or other communication types referred) the current infusion parameters and also diagnostic devices limits. So shift nurse can analyze data received, and may energize an application preferably Java J2ME on her mobile, with which can see and modify the infusion parameters (titration) just received from the pump, so the patient can have pain relief. New parameters can be sent in a form, which can be preferably SMS or email, as point to point to the SIM card of the pump, or TCP/IP packets initiated from J2ME application and passing through the connected server. For security, it is needed that the cycle ends by a confirmation of titration from the same or third route like watching therapy personnel or doctor, using a code.
  • SMS Short titration
  • the direct to nurse SMS in this case helps in cost assignment to one point (the SIM card of the telemedicine mobile system) and also avoid delays or discontinuities from a longer information path.
  • GSM Cellular phone service
  • GPRS Data always ON connection service on cellular phone known as 2,5 generation system
  • UMTS Service of high speed data, always connected cellular telephony, enabling also video known as 3 rd generation
  • SMS Short Messages Service over cellular telephony
  • MMS Short messages including images and other files atached
  • PSTN Standard ground based telephony
  • TCP/IP Internet data integrity protocol
  • SIM card a cellular phone interface card, which holds data and the Number of the phone used.
  • PCA Patient Controlled Analgesia

Abstract

La présente invention concerne un petit système conçu pour transmettre, à distance d'une personne chargée de la télésurveillance, des informations concernant des données fonctionnelles de dispositif permettant la mise en oeuvre d'une médecine à distance. Le système décrit dans cette invention utilise une connexion simple point à point ponctuelle (la communication s'achève après transmission du paquet et réponse éventuelle), ou également un simple message SMS, au moyen d'un carnet d'adresses pouvant être mis à jour. Selon le mode de réalisation décrit dans cette invention, les données médicales transférées sont adaptées de manière à permettre aux infirmières qui s'occupent de patients à domicile de superviser des dispositifs diagnostiques et thérapeutiques à distance, et d'éviter ainsi des visites inutiles. Cette invention concerne également des alarmes spéciales permettant de réduire les coûts de mise en oeuvre. Plus particulièrement, la pompe peut être programmée à partir d'un autre point, par exemple, un terminal mobile.
